If Ryzen was a polite, if firm way of telling the world that AMD is back in the processor game, then Threadripper is a foul-mouthed, middle-finger-waving, kick-in-the-crotch “screw you” aimed squarely at the usurious heart of Intel. It’s an olive branch to a part of the PC market stung by years of inflated prices, sluggish performance gains, and the feeling that, if you’re not interested in low-power laptops, Intel isn’t interested in you.

Where Intel charges $1,000/£1,000 for 10 cores and 20 threads in the form of the Core i9-7900X, AMD offers 16C/32T with Threadripper 1950X. Where Intel limits chipset features and PCIe lanes the further down the product stack you go—the latter being ever more important as storage moves away from the SATA interface—AMD offers quad-channel memory, eight DIMM slots, and 64 PCIe lanes even on the cheapest CPU for the platform.

Threadripper embraces the enthusiasts, the system builders, and the content creators that shout loud and complain often, but evangelise products like no other. It’s the new home for extravagant multi-GPU setups, and RAID arrays built on thousands of dollars worth of M.2 SSDs. It’s where performance records can be broken, and where content creators can shave precious minutes from laborious production tasks, while still having more than enough remaining horsepower to get their game on.

Sure, dive deep into the technicalities and Intel’s Skylake-X is still the absolute fastest when it comes to pure instructions-per-clock performance and high-frame-rate gaming. But the sheer daring of AMD Threadripper and accompanying X399 platform is nothing short of astonishing. Its performance, particularly in content creation tasks and production workloads, wipes the floor with the Intel equivalent. Taken as a whole, there really is no competition—Threadripper is the High End Desktop (HEDT) platform to beat.

Double trouble

When AMD unveiled its Zen architecture, which finally morphed into a product as Ryzen, much was said about Infinity Fabric, the company’s new interconnect designed for maximum scalability. The 14nm FinFET Zen core is designed as a four-core-complex (CCX), with Infinity Fabric used to bind two CCX together to create the eight-core CPUs of Ryzen 7. What many didn’t quite realise at the time is just how well Infinity Fabric would work (after a few teething troubles were resolved, at least) and just how far AMD could push it.

Threadripper 1950X is effectively two eight-core Ryzen 1800X CPUs placed onto the same package joined together by Infinity Fabric. The result is a CPU measuring a mammoth 72mm by 55mm, which slots into the even larger TR4 motherboard socket. Threadripper is, physically at least, the biggest consumer CPU released since the cartridge slot format of the Pentium 2—and even then the CPU itself was just a small part of the cartridge.

The retail experience

AMD has embraced Threadripper’s ample frame with aplomb. It comes in ludicrously ostentatious retail packaging that’s as oversized and dramatic as the CPU itself. Opening it is a multistage process of tearing through paper seals, twisting a latch to “unlock the power,” and removing steel clamps and protective windows.

Yes it’s over-the-top, and yes, it’s a little bit silly. But the eye-catching packaging and involved unboxing experience is as much as testament to AMD’s bullish bid to woo the enthusiast as it is to an over zealous marketing team.

The advantages and disadvantages of AMD’s Infinity Fabric design are well documented at this point—and I’d advise taking a look at Peter Bright’s excellent deep dive into the Zen architecture to learn more—but many of the quirks that arose from it have since been patched out or tweaked. Do note, however, that Infinity Fabric performance still depends greatly on memory speed. Thankfully, running 3200MHz memory with a Threadripper CPU is as simple as loading an XMP profile—a far cry from the memory issues that plagued Ryzen at launch.

Indeed, with Threadripper being based so heavily on Ryzen, it’s a pleasingly stable platform. The only real difference is the memory configuration—which is now quad-channel with ECC support, thanks to the two dual-channel controllers present on each eight-core die—and the PCIe lane configuration, which now features 64 lanes, four of which are reserved for connection to the new X399 chipset.

With Threadripper, you can run two graphics cards at X16 PCIe speeds, two at X8, and still have enough lanes left over for three X4 NVMe SSDs connected directly to the CPU. Intel’s i9-series offers a mere 44 PCIe lanes on the CPU by comparison, but does make up the difference with a further 24 lanes on the motherboard (they do, however, share a single X4 PCIe link to the CPU).

There are two Threadripper CPUs available at launch: the 16C/32T 1950X, and the 12C/24T 1920X. Both feature the same 512K of L2 cache per core (8MB total), 16MB per die (32MB total) of L3 cache, and 4.0GHz boost clock across four cores. They can both boost as far as 4.2GHz across the same four cores thanks to AMD’s XFR (extended frequency range) enhancements, which offer increased clock speeds for those with suitably robust cooling setups. The only difference between them is the slight base clock bump to 3.5GHz on the 1920X, versus the 3.4GHz of the 1950X. Like the rest of the Ryzen line-up, both Threadripper CPUs are fully unlocked for overclocking.

At $1,000/£1,000, the 1950X offers 16C/32 where Intel offers just 10C/20T. While Intel’s superior IPC performance and clock speeds do make up some of the difference, to get the same core count with an i9 costs $1,700, while the the top-end 18C/36T i9-7980XE costs an eye-watering $2,000. The 1920X fares even better, offering 12C/24T for $800. Intel doesn’t have an equivalent chip for the price, only the more expensive i9-7900X, or the $600 i7-7820X, which features a mere 28 PCIe lanes and just eight cores. Simply put, AMD offers a lot more for a lot less.

The AMD Ryzen Threadripper 1950X and 1920X Review: CPUs on Steroids

In the early 2000s, we had the battle to high frequencies. The company that could force the most cycles through a processor could get a base performance advantage over the other, and it led to some rather hot chips, with the certain architectures being dropped for something that scaled better. Move on 10-15 years and we are now at the heart of the Core Wars: how many CPU cores with high IPC can you fit into a consumer processor? Up to today, the answer was 10, but now AMD is pushing the barrier to 16 with its new Threadripper processors. We got both of the launch CPUs for review and put them on the grill.

Henrik Fisker interview: the EMotion EV, and a ‘game-changer’ charging method

In Torrance, Calif., a Danish-born designer-cum-CEO is putting his own name behind a car company he’s building. It’s not the first time

Henrik Fisker

has done this, but perhaps it’ll go a little more smoothly this time around. The timing seems better for what he wants to do, which is launch a high-end, long-range

electric vehicle

.

It’s not settled where

Fisker

will build its first car, the $129,900

EMotion EV

, yet. The company is looking to buy an existing factory but hasn’t chosen one yet. Henrik Fisker tells us they’ve looked at a few, but with no hint of pressure in his voice, says, “We don’t have to make a decision until the end of the year.” Fisker expects to begin producing the EMotion in 2019.

FISKER EMOTION: THE BASICS

The Fisker EMotion is powered by two electric motors, one in the front and one in back, giving it all-wheel drive. Fisker told us the EMotion has “a new type of electric motor that we are working on together with a very large supplier.” He said it’s efficient, light, and compact, but declined to offer up other details, including output. That announcement will come later.

In terms of aerodynamics, Fisker says there’s a limit to what you can do and still make the vehicle look nice. “You can make a pretty

ugly car

that’s very aerodynamic. You probably remember the

GM

EV1 that was super aerodynamic, but not necessarily a very pretty car. The Fisker brand is about good-looking cars.”

Fisker says, though, that there are aero benefits that an electric powertrain makes possible. He was able to lower the front of the EMotion, which he says really makes this four-door look evolved compared to the traditional sedan. With no gasoline engine up front, that lowered cowl also improves the view of the road ahead. Because of its electric layout, The EMotion is able to have its wheels at the very corners, with minimal front and rear overhang. The car features what Fisker calls a “very, very dramatic” functional rear diffuser, which takes advantage of the EV’s flat underside. The EMotion also has a small integrated rear spoiler, and airflow around the wheels was optimized without disrupting the car’s sculptural look.

With the EMotion, Fisker wants to blend sport with luxury. Again, thanks to the packaging of the electric powertrain, the company is able to create a roomy interior by pushing the windshield forward and the rear window back. Fisker even goes so far as to compare the rear legroom to that of a

BMW

7 Series. We’ll have to wait for full interior details, as Fisker plans to make further announcements later in the year (which is hard to imagine, looking at the EMotion’s exterior, until you notice how far back the rear doors are placed in comparison with the rear wheels).

With more people living and using cars in big cities, low-speed comfort is becoming more important. Fisker intends to deliver on that with the EMotion. As we spend more time driving in a different environment than we did 10 or 20 years ago, Fisker told us, “We have to emphasize in different things [than just driving dynamics] how to have fun driving a vehicle. Part of that will be a whole different interface in our vehicle, which we are working on in-house, to create more excitement, more entertainment.” He adds, “In autonomous driving, specifically in stop-and-go traffic, you need to have something else to do.” The car should also be fun to drive, and because EVs are so quiet, Fisker is working on ways to “engage the senses” while driving.

The car should also be quick and handle well, especially at $129,900. Other automakers have already proven EVs can be fast, and Fisker is also working on handling. The EMotion’s all-wheel drive and low center of gravity (thanks to the battery pack) improve the car’s handling. He says the EMotion’s carbon fiber rims are 40 percent lighter than aluminum wheels, and the body uses carbon fiber as well, to help make the car light and quick.

ENERGY

The Fisker EMotion’s lithium-ion battery pack is uses 21700 cylindrical cells from

LG Chem

with NCM (nickel-cobalt-manganese) cathode chemistry. To keep the actual physical volume of the battery down, Fisker has created its own cooling system that helps increase energy density. Fisker says the battery pack will offer the highest energy density in the world. The 21 modules that make up the pack sit extremely low in the vehicle. Their thin profile helped Fisker take advantage of the space inside the vehicle, providing that roominess we discussed earlier.

There won’t be a variety of battery options in the Fisker EMotion. Every car, beginning with the $129,900 base model, will come with the same UltraPack, offering over 400 miles of driving range. “At least the plan at this point is not to offer it with a smaller battery pack. We really want to show this as the ultimate

electric car

.”

Even if people don’t normally drive 400 miles in a day, range is important to the consumer. Fisker asked, why aren’t more people buying electric vehicles? He identified range and charging time as two key solutions that would get more people into EVs. The EMotion’s 400-plus-mile range should take care of range anxiety, allowing more flexibility to travel longer distances or to own EVs in places where infrastructure is limited (and to make people feel like they aren’t giving something up by switching to an EV). That second part of the equation — charging — is where things get really interesting.

Fisker’s not happy with the idea of stopping at a destination, such as a mall, where it takes an hour or so to charge (assuming there’s a charging point available). Instead, Fisker envisions a new standard of chargers, which he calls “Ultrachargers,” located at

gas stations

. He tells us his company is in talks with big oil companies to install these Ultrachargers at their retail locations. While the Fisker EMotion will be an expensive vehicle, it’s this charging technology that he thinks will eventually get the masses into EVs. But what is it?

“We are working on this new charging, which is a different type of charging. It’s not a cable, and it’s not inductive charging. We can’t really reveal it yet — we’re working on prototypes right now — ­but I think this could be a new standard where you actually don’t even have to get out of the car to charge the vehicle.”

Boy, did our ears perk up at that. Without getting into too much detail, Henrik Fisker told us that his company is working on prototypes for this new type of charger with ABB, a European provider of fast charging infrastructure. The EMotion will still be able to use the same types of charging stations we have today (it will use the CCS charging standard), “but we also want to launch it with this new type of charger, which we think is pretty exciting,” Fisker said, “and a game-changer.”

AUTONOMOUS DRIVING

Interestingly, Henrik Fisker downplayed the idea of autonomous driving during our conversation, despite the fact that the EMotion makes use this technology.

Fisker doesn’t think customers are all that interested in sitting and doing other activities while doing 70 miles per hour on an open road. It’s the stop-and-go traffic that’s frustrating, and that’s the problem autonomous driving capabilities help to solve. “That’s when probably most people are tending to start playing with your entertainment system or picking up your phone. So, we are really looking at that space to be able to truly take your hands off the steering wheel and do something else.”

Not being able to take your hands off the steering wheel when you have autonomous capability, Fisker says, is “like having a passport, but you can’t leave the country.” Fisker thinks it makes the most sense in terms of safety to offer hands-free driving at low speeds, specifically in a traffic jam on the freeway, where there aren’t any pedestrians and any accident would have milder consequences. Like the rest of us, he’s unsure how the legislation surrounding self-driving cars will shake out, so he’s not leaning too heavily on that aspect of the vehicle to sell it.

SERVICE AND DISTRIBUTION

Fisker has

announced a partnership

with

The Hybrid Shop

— which Fisker says will be called “The EV and Hybrid Shop” –— which will service the EMotion. Currently, there are 36 Hybrid Shops. At the launch of the EMotion, Fisker said he expects there to be about 250 in the U.S. Fisker wants to revolutionize that facet of ownership, though, and make it as seamless as possible.


“You can do a lot of stuff over the air, but eventually there are tires that are going to need to be changed, or something’s going to happen with the car that needs service,” Fisker said. “When that happens, we have a predictive service where basically the car’s fully connected with The Hybrid Shop infrastructure.” So when something goes wrong, or is about to go wrong, the owner doesn’t have to do anything. The car is connected to your calendar, and knows when you won’t be using it. It will send you a notification suggesting a pickup time for you to approve. After that, technicians can pick up your car while you’re at work using a digital key, service it, and return it to you before the end of the work day.

This is meant to make it easier to live with the car. Fisker says this new service model and self-parking are the best solutions for people who live in big cities ­— the same people who are more likely to put off

buying a car

because of the inconvenience.

When a customer buys a Fisker EMotion, either online or at one of the company’s planned “Experience Centers,” those same Hybrid Shop service centers will be the ones who prepare and deliver the

new vehicle

. Customers will be able to take a virtual or real test drive, spec and order their car, and a “concierge” will deliver it to them at their home or workplace with everything ready to go, down to installing the customer’s various preferences in the interfaces.

LOOKING DOWN THE ROAD

Fisker learned from his last venture and is applying that knowledge to this new one. He tells us that the EMotion will be a lower-volume vehicle, and that making use of advanced, lightweight materials like carbon fiber and aluminum and the like means a lower investment in tooling. “Of course,” Fisker said, “it also means the car will be more expensive.” He said he wants to use this car to showcase the company’s technology, so that it can return later with “a higher-volume vehicle for a much lower cost.”

Fisker wouldn’t tell us what that next vehicle would be, but he said it would be on a different platform from the EMotion. “We have a very clear idea what the next car will be,” he said, “but we don’t want to say it yet. But it will be a very affordable vehicle.” The costs of batteries and electrical components are a challenge, but he’s encouraged by what LG Chem is doing in that regard.

Fisker believes, though, that solid-state is the future of batteries. His company is working on graphene and solid state technology, and already has patents. He’s not sure when that tech will be ready for commercialization, but it won’t be in time for the EMotion, and probably past 2022 or 2023, he said. “At that point in time, the electric car will be fully superior to a gasoline car in any aspect — price, performance, everything.”

Of course, Fisker

isn’t the only one

who believes solid state batteries are the future.

Toyota

,

Kia

, and others are working on this technology as well. “I personally feel like we might be one of the ones that are furthest along. We have a great battery chemistry team, and that’s something that’s kind of unusual, but I really decided that that’s one of the areas where we want to spend a lot of effort in-house.” Researching and developing battery chemistry, modules, and charging are important to tackle in-house, “because those are the things we have to solve to make the electric car mass-market and superior to a gasoline car.”

Henrik Fisker believes that 10 years down the road, EVs will achieve about 20 percent market penetration in the U.S., and more than that in the parts of the world that do more to promote electrification. That’s why he’s happy to be starting anew with an all-electric vehicle. He wishes

Karma Automotive

luck with the Revero, but says, “I obviously wanted to move forward and do what I feel is innovative and something for the future.” He adds, “When we started the

Fisker Karma

way back, at that time, the battery technology was still not where we wanted it to be, which is why we chose a

plug-in hybrid

. I think today we are now far enough that we can get, like I say, that range that at least I would want. I think battery electric cars will be the future.”

And because the number of cars on the road is going to increase, they need to be environmentally friendly, Fisker said. Carsharing, ride-hailing,

autonomous vehicles

, these all transfer usage from public transportation ro smaller vehicles with fewer people in them (but on a more direct route). “We will probably have even more driven miles in the future than we have today,” Fisker said. And a lot of those miles will be in cars, whether we’re the ones controlling them or not.

That’s why electric cars are increasingly necessary for a clean environment. “But I also think,” Fisker said, “that electric cars need to be fun and cool and desirable.” And that’s where Fisker Inc. sees itself. The company wants to “make a cleaner environment, but [do] it while having fun. We’ll let other people make the boring cars, because I’m sure they’re going to be there as well.”

WHAT ABOUT VLF AUTOMOTIVE?

Fisker thinks about

VLF

as a “hobby shop,” or a “kid’s dream.” He told us, “We no aspirations of being a giant car company or anything. It’s kind of three guys —

Bob Lutz

, and Gilbert [Villarreal], and myself — having fun. We don’t have any marketing department, you know. We just make the car we think will be cool, and we hope somebody’s going to buy it.

He sees the VLF product — low-volume, high-performance, internal-combustion

supercars

— as “almost like a mechanical watch that nobody really needs anymore, but they’re still fun and cool.”

“I actually think that in the future, the boring gasoline cars are going to be unnecessary, because you might as well be driven, or drive an electric car when you do your daily commute. But, just like it’s fun to have a mechanical watch, it still will be fun to have a

sports car

where you really interact with the mechanics of the vehicle, and you may only do it on the weekend, for fun. And that’s kind of what we do at VLF.”

“It’s like when you go out and just have a steak without even a salad.”

AMERICA FIRST

Henrik Fisker left us with some parting words at the end of our conversation. He told us he believes that “America is leading in electric vehicle development,” and points to startups in California as evidence of that. “Once the electric car takes off in the mass market, we want America to be the leader in that, because that’s going to be the most important technology going forward.”

Tesla developing self-driving tech for semi-truck, wants to test in Nevada

Tesla

Inc is developing a long-haul, electric semi-truck that can drive itself and move in “platoons” that automatically follow a lead vehicle, and is getting closer to testing a prototype, according to an email discussion of potential road tests between the car company and the Nevada Department of Motor Vehicles (

DMV

), seen by Reuters.

Meanwhile, California officials are meeting with Tesla on Wednesday “to talk about Tesla’s efforts with autonomous trucks,” state DMV spokeswoman Jessica Gonzalez told Reuters.

The correspondence and meeting show that Tesla is putting self-driving technology into the electric truck it has said it plans to unveil in September, and is advancing toward real-life tests, potentially moving it forward in a highly competitive area of commercial transport also being pursued by

Uber

Technologies Inc and Alphabet Inc’s Waymo.

After announcing intentions a year ago to produce a heavy-duty electric truck, Musk tweeted in April that the semi-truck would be revealed in September, and repeated that commitment at the company’s annual shareholder meeting in June, but he has never mentioned any autonomous-driving capabilities. Tesla has been a leader in developing self-driving technology for its

luxury cars

, including the lower-priced Model 3, which it is beginning to manufacture.

Several Silicon Valley companies developing autonomous driving technology are working on long-haul trucks. They see the industry as a prime early market for the technology, citing the relatively consistent speeds and little cross-traffic trucks face on interstate highways and the benefits of allowing drivers to rest while trucks travel.

Some companies also are working on technology for “platooning,” a driving formation where trucks follow one another closely. If trucks at the back of the formation were able to automatically follow a lead vehicle, that could cut the need for drivers.

Silicon Valley startup Peloton Technology, for example, is working with several truck makers including

Volvo

on its platooning system, which it sees as a precursor to autonomy.

Tesla’s high-flying shares, up almost 70 percent this year, closed down 0.5 percent at $363.53 on Nasdaq, but rose slightly after hours.

An email exchange in May and June between Tesla and Nevada DMV representatives included an agenda for a June 16 meeting, along with the Nevada Department of Transportation, to discuss testing of two prototype trucks in Nevada, according to the exchange seen by Reuters.

“To

insure

we are on the same page, our primary goal is the ability to operate our prototype test trucks in a continuous manner across the state line and within the States of Nevada and California in a platooning and/or Autonomous mode without having a person in the vehicle,” Tesla regulatory official Nasser Zamani wrote to Nevada DMV official April Sanborn. He made no reference to any dates for potential road tests.

No companies yet have tested self-driving trucks in Nevada without a person in the cab. On July 10, Zamani inquired further to the Nevada DMV about terms for a testing license, an email seen by Reuters shows.

California DMV spokeswoman Gonzalez said that Tesla had requested a meeting on Wednesday to introduce new staff and talk about Tesla’s efforts with autonomous trucks. She said that the DMV was not aware of the level of autonomy in the trucks.

Tesla declined to comment on the matter, referring Reuters to the previous statements by Musk, who has discussed the truck in tweets and at the annual shareholder meeting.

Nevada officials confirmed the meeting with Tesla had occurred and said that Tesla had not applied for a license so far. They declined to comment further.

Musk has said that potential customers are eager to get a Tesla electric long-haul truck, but he faces doubt that the company can deliver.

While established trucking companies and truck manufacturing startups have poured resources into electrifying local package delivery fleets, battery range limitations have largely kept the industry from making electric trucks that travel across swaths of the country.

Lithium ion battery researcher Venkat Viswanathan of Carnegie Mellon University said electric long-haul trucking is not economically feasible yet.

“Your cargo essentially becomes the battery,” Viswanathan said of the massive batteries that would be needed to make range competitive with

diesel

.

Diesel trucks used for cross-country hauls by United Parcel Service Inc can travel up to 500 miles (800 km) on a single tank, according to UPS’s director of maintenance and engineering, international operations, Scott Phillippi. By comparison, the company’s electric local package

delivery trucks

travel up to 80 miles on a full charge.
