One of AMD’s skills in recent quarters is the ability to drip feed information about upcoming products slowly to the point where even the breath of a clock speed becomes another several column inches about an upcoming platform. Today’s announcements are as juicy as an average minute steak, giving details confirming the launch dates for the first two Threadripper processors, some in-house performance comparisons, and also information about a third cut of the ingot coming at the end of the month.

Threadripper Gets a Launch Date

The news at the top of the hour is the date at which AMD is making Threadripper and associated TR4 based motherboards available at retail: August 10th. This is expected to be a full worldwide retail launch, so don’t be surprised if your favorite retailer starts posting teaser images about how much stock they have. August 10th will see both the 1950X and 1920X with their retail packaging, along with motherboards from the main four motherboard vendors.


The image used up the top was posted on Twitter a few days ago by AMD showing the retail packaging, and a Dr Lisa Su, CEO of AMD, for scale. The base retail package does not come with a cooler, but does come with a spacer and Torx wrench, as the socket requires a full Torx screwdriver to access it. AMD has engineered an ecosystem of both closed liquid loop coolers partners, as well as a few air coolers capable of meeting the 180W TDP required. We’re looking into exactly which models will have the appropriate support.

AMD is allowing pre-orders for partner systems and boutique OEMs to start from July 31st. Dell’s Area-51 Threadripper edition has been highly covered already, and it was always a question as to why they were allowed to announce earlier than everyone else. The answer was that they secured an exclusive, but it seems only for four days, from the 27th. Nonetheless, other system integrators such as MainGear, OverclockersUK, iBUYPOWER, Origin, Velocity Micro and others will be showing systems from today.

From the motherboard vendor side, this week has seen the main four companies lift the lid on some of their AM4 designs further to what we saw back at Computex. ASRock, ASUS, GIGABYTE and MSI will all be launching motherboards on day one, making full use of the quad channel memory with two DIMMs per channel and 60 PCIe lanes for add-in cards (using another four for the chipset, which we typically do not count to some users’ chagrin). We’re planning a full overview of each board, but keep eyes out for:

ASUS X399 ROG Zenith Extreme and ASUS PRIME X399-A

ASRock X399 Professional Gaming and ASRock X399 Taichi

GIGABYTE X399 Gaming 7 and MSI Gaming PRO CARBON AC

At present all the boards being shown are ATX or E-ATX. We’re unlikely to see any mini-ITX due to the size of the socket however microATX might be possible further down the line. No word on pricing for these yet, except that one of the system integrators has priced the ASUS X399 Zenith at +$227 over the GIGABYTE X399 Gaming 7 in their configurator, which suggests the boards will range in price from $300 to $600 pretty easily (add in some knowledge we already have on the BOM cost of some of these parts).

Threadripper 1950X Performance: AMD Gave A Number

Having a few threads in hand at a high frequency means that any benchmark which is thread dense and register light is going to scale very well. AMD shared one data point (which we cannot confirm) from their recent favorite benchmark, Cinebench R15.

The number given was 4122, representing a 5.2 GHz overclocked (under liquid nitrogen, so not a daily OC) Threadripper 1950X. If we scale this down to 3.5 GHz for the all-core turbo of 1950X, we get a score more around 2774. One of the scores in the screenshot above is 3099, which equates to a 3.9 GHz all-core frequency.

We have some old dual socket CB15 numbers in our database, under Windows 7. There are a fair number of old dual socket workstations around for compute tasks, and TR 1950X (if these numbers are true) beats systems such as a dual socket Ivy Bridge-EP based E5-2687W v3 when running all cores near turbo frequency, which would have retailed at launch for $4200+ just in processors and at a much lower TDP than two of the older processors combined.

Threadripper The Third: The Threadripper 1900X at $549, coming August 31st

To sprinkle some salt onto the steak today is the announcement of a third TR processor. The 1900X is an eight-core part, with a base frequency of 3.8 GHz, a turbo of 4.0 GHz, and +200 MHz of XFR.

There are some questions around why AMD would release an 8-core Threadripper, given that the Ryzen 7 1800X is also eight core and currently retails around $399 when distributor sales are factored in. The main thing here is going to be IO, specifically that the user is going to get access to quad channel memory and all the PCIe lanes required for multi-GPU or multi-add-in cards, along with a super high-end motherboard that likely contains multiple CPU-based PCIe x4 storage and/or 10G Ethernet and additional features.

Naturally, with the eight cores being split over two Zeppelin dies (see side note), there is going to be some extra latency between the cores on each of the dies. AMD is countering this by having a higher base frequency (due to the TDP headroom), and stating that the chip allows overclocking. Obviously, some fine-tuned crank is needed and with any luck, it should run 4.0 GHz on all cores.

That Side Note

In the last week, Caseking system builder and overclocker Der8auer (Roman Hartung) released a video de-lidding a supposed Threadripper engineering sample, to which the video was taken down at the request of AMD less than 24 hours later. In the video, he showed that underneath his engineering sample (the ones that AMD gives to system integrators like Caseking to configure systems they will make available) were four silicon dies:

Obviously with Threadripper only going up to 16 cores, and EPYC which uses a similar package going up to 32, we were expecting to see TR with only two bits of silicon, not four. Roman states that only two of the dies are enabled, which simplifies things, but there are a few caveats here to note.

First, this was a Threadripper ES and the retail chips could be quite different. Roman deliberately covered up the markings on the processor on the video (although some images got out), and it was unclear what stage ES this was – as AMD could very likely just give half-disabled EPYCs with different notches in the first ES batches. Simply put, retail Threadripper chips could only have two.

There are several reasons why there could be four though. One suggestion is that these are ‘failed’ EPYCs, although AMD would say that is not the case. If AMD were putting four die onto a chip and disabling two, that would be really bad for the price on return per die, so what is going on here? Simply put, the two ‘disabled’ die aren’t engineered silicon at all, just simple silicon that hasn’t been put through the manufacturing process and added in as spacers for package rigidity. With the Threadripper package being so large, having four places for the mass of the coolers to press onto in the socket for better contact with the socket pins, using spacers would help spread that weight around. There have been suggestions it might help with heat dissipation, but that is unlikely as any heat transfer would be through the TIM and the HS, not through the package itself which is fairly thermally insulating.

To sum up:

  • This is an early Engineering Sample, and might not be indicative of retail
  • Only 2 of the 4 dies are even active
  • If it is retail, 2 inactive dies are likely empty silicon for rigidity

If this is even indicative of a Threadripper retail sample (again, no confirmation it is), our guess is that these two extra ‘dies’ is just empty silicon used for rigidity. So anyone claiming to get 32 cores through unlocking software is not telling the truth. But consider that it should allow AMD to push 32 cores with a quad-channel memory design into the TR4 socket if they wanted in the future. That depends on how long this platform is expected to be around, likely through to Zen 2 at a minimum and perhaps Zen 3 as well. I’ll go ask AMD.

    So, AMD is only giving YOU watermarked images, while the rest of the sites get non-watermarked?

    Geez, maybe it is high time you remove that "The Most Trusted in Tech Since 1997" ;)

    Listed mobos for now at 350$ and up, this platform is DOA ,they need cheaper SKUs and cheaper mobos.
    Otherwise the not clueless folk will just get Naples.

    Isn't that actually pretty decent for workstation motherboards? They usually go upwards of $500. I guess it depends on the details and what you get onboard, but I wouldn't compare the prices to standard desktops. The Intel x299 Aorus 7 is $399. Reply

    Also keep in mind the Epyc (and comparable xeons for that matter) are in the 2.1-3.0Ghz range. So you may get even more IO at about the same price for CPU and maybe a $500 server motherboard, you lose a lot of single threaded performance. Threadripper seems to be less compromise on that front.

    There you go dropping facts and such. How dare you, sir! Reply

    If you think Threadripper and its platform are expensive then HEDT is not for you. This isn't for your gaming machine, granted yes you can game on it, its for workstations doing real work using 32 threads. This will be the cheapest 32 thread CPU to land on a consumer i.e. no server platform ever. Reply

    $549 for the 1900X is a pleasent surprise.
    $549 for the 1900 and and $599 for 1900X seemed to be the logical price points.
  • sor - Monday, July 31, 2017 - link

    The 1900X is going to be a great CPU. I was hoping they'd do this, as I don't necessarily need 12 cores but I want the PCIe lanes. Not too expensive, extra MHz, thermal headroom for overclocking, all of the IO bells and whistles. Reply

    What! No Mini-STX boards for launch? Lol Reply

    I'm holding out for the 35W models. :P Reply
