AMD's Threadripper 2 TR 2990WX will be available for retail on August 13. The CPU has 32 cores and the suggested retail price is $1,799, compared to $1,999 for Intel's 18-core i9-7980XE. A 24-core TR 2970WX will be available in October for $1,299.
The 16-core TR 2950X ($899, August 31) and 12-core TR 2920X ($649, October) replace their counterparts from the last generation of Threadripper CPUs, but have slightly improved "12nm" Zen+ cores like the other Threadripper 2 CPUs. The 16 and 12-core chips use 2 dies while the 24 and 32-core versions use 4 dies.
A benchmark leak shows the 32-core TR 2990WX outperforming Intel's 18-core i9-7980XE by 53% in the multithreaded Cinebench R15 (this is an early result, may not represent the final performance, and may be overly favorable to AMD).

AMD Ratcheting Up the Pressure on Intel
AMD's TR 1950X (16 cores) and TR 1920X (12 cores) CPUs will be released on August 10th:
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.
AMD has also announced an 8-core version of Threadripper, the TR 1900X, for $549. Why buy it instead of spending $300 on the Ryzen 7 1700 or $420 on the Ryzen 7 1800X, both of which have eight cores?
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.
AMD released Threadripper CPUs in 2017, built on the same 14nm Zen architecture as Ryzen, but with up to 16 cores and 32 threads. Threadripper was widely believed to have pushed Intel to respond with the release of enthusiast-class Skylake-X chips with up to 18 cores. AMD also released Epyc-branded server chips with up to 32 cores.
This week at Computex 2018, Intel showed off a 28-core CPU intended for enthusiasts and high end desktop users. While the part was overclocked to 5 GHz, it required a one-horsepower water chiller to do so. The demonstration seemed to be timed to steal the thunder from AMD's own news.
Now, AMD has announced two Threadripper 2 CPUs: one with 24 cores, and another with 32 cores. They use the "12nm LP" GlobalFoundries process instead of "14nm", which could improve performance, but are currently clocked lower than previous Threadripper parts. The TDP has been pushed up to 250 W from the 180 W TDP of Threadripper 1950X. Although these new chips match the core counts of top Epyc CPUs, there are some differences:
At the AMD press event at Computex, it was revealed that these new processors would have up to 32 cores in total, mirroring the 32-core versions of EPYC. On EPYC, those processors have four active dies, with eight active cores on each die (four for each CCX). On EPYC however, there are eight memory channels, and AMD's X399 platform only has support for four channels. For the first generation this meant that each of the two active die would have two memory channels attached – in the second generation Threadripper this is still the case: the two now 'active' parts of the chip do not have direct memory access.
This also means that the number of PCIe lanes remains at 64 for Threadripper 2, rather than the 128 of Epyc.
Threadripper 1 had a "game mode" that disabled one of the two active dies, so it will be interesting to see if users of the new chips will be forced to disable even more cores in some scenarios.
Intel expects to lose some server/data center market share to AMD's Epyc line of chips:
The pitched battle between Intel and AMD has spread to the data center, and while Intel has been forthcoming that it expects to lose some market share in the coming months to AMD, Brian Krzanich's recent comments to Instinet analyst Roman Shah give us some insight into the surprising scope of AMD's threat. Shah recently sat down with Intel CEO Brian Krzanich and Barron's reported on his findings:
Shah relates that Krzanich "was very matter-of-fact in saying that Intel would lose server share to AMD in the second half of the year," which is not news, but he thought it significant that "Mr. Krzanich did not draw a firm line in the sand as it relates to AMD's potential gains in servers; he only indicated that it was Intel's job to not let AMD capture 15-20% market share." (emphasis added).
Furthermore, Intel's problems with the "10nm" node could allow AMD to pick up market share with "7nm" (although it may be similar in performance to Intel's "10nm"):
Nomura Instinet is less bullish on further stock gains for Intel after talking to the chipmaker's CEO, Brian Krzanich. [...] The analyst said Intel's problems in moving to its next-generation chip manufacturing technology may be a factor in its potential market share losses. The chipmaker revealed on its April 26 earnings conference call that it delayed volume production under its 10-nanometer chip manufacturing process to next year. Conversely, AMD said on its call that it plans to start next-generation 7-nanometer chip production in late 2018.
[...] "We see Mr. Krzanich's posture here reflecting the company's inability thus far to sufficiently yield 10nm for volume production while AMD's partner TSMC is currently making good progress on 7nm; thus, setting Intel up for stiff competition again in 2019," the analyst said.
Here are a couple of post-mortem articles on Intel's misleading 28-core CPU demo and more:
Rather than 28 cores, Intel may introduce 20 and 22 core CPUs to compete with AMD's Threadripper 2, along with 8-core Coffee Lake refresh CPUs to compete with Ryzen.
Among many of Intel's announcements today, a key one for a lot of users will be the launch of Intel's 9th Generation Core desktop processors, offering up to 8-cores on Intel's mainstream consumer platform. These processors are drop-in compatible with current Coffee Lake and Z370 platforms, but are accompanied by a new Z390 chipset and associated motherboards as well. The highlights from this launch is the 8-core Core i9 parts, which include a 5.0 GHz turbo Core i9-9900K, rated at a 95W TDP.
[...] Leading from the top of the stack is the Core i9-9900K, Intel's new flagship mainstream processor. This part is eight full cores with hyperthreading, with a base frequency of 3.6 GHz at 95W TDP, and a turbo up to 5.0 GHz on two cores. Memory support is up to dual channel DDR4-2666. The Core i9-9900K builds upon the Core i7-8086K from the 8th Generation product line by adding two more cores, and increasing that 5.0 GHz turbo from one core to two cores. The all-core turbo is 4.7 GHz, so it will be interesting to see what the power consumption is when the processor is fully loaded. The Core i9 family will have the full 2MB of L3 cache per core.
[...] Also featuring 8-cores is the Core i7-9700K, but without the hyperthreading. This part will have a base frequency of 3.6 GHz as well for a given 95W TDP, but can turbo up to 4.9 GHz only on a single core. The i7-9700K is meant to be the direct upgrade over the Core i7-8700K, and although both chips have the same underlying Coffee Lake microarchitecture, the 9700K has two more cores and slightly better turbo performance, but less L3 cache per core at only 1.5MB per.
