AMD Announces Ryzen Threadripper PRO 9000 "Shimada Peak" HEDT Processors
AMD at Computex 2025 announced the Ryzen Threadripper PRO 9000 series processors targeting high-end desktops (HEDT) and workstations. These processors are codenamed "Shimada Peak," and are based on the "Zen 5" microarchitecture. "Shimada Peak" is a variation of the EPYC "Turin" MCM, designed for Socket TR5, with slightly modified I/O. The chip puts out up to 128 PCIe Gen 5 lanes but lacks CXL capability on these lanes, and the memory I/O is set to 8-channel DDR5 (16 sub-channels), down from 12-channel DDR5 on "Turin" (24 sub-channels).
The top SKU, the Ryzen Threadripper PRO 9995WX, comes with a 96-core/192-thread configuration, a 128-lane PCIe Gen 5 I/O, and an 8-channel DDR5 memory interface. The chip comes with a maximum boost frequency of 5.40 GHz, and a total of 384 MB of L3 cache (12x 32 MB). AMD claims a significant 10-20% gain in Cinebench 2024 nT performance over the previous generation 7995WX "Zen 4" processor, and nearly 220% gain over the Intel Xeon W9-3595X processor. Across a wide segment of media, design, architecture, science, and LLM inferencing use-cases, the 9995WX is shown posting performance leads ranging anywhere from 44% to 145% over the W9-3595X. The Threadripper PRO 9000 series will be an OEM-exclusive launch through workstation partners such as Lenovo.Much like the Ryzen Threadripper 7000 series "Storm Peak," the Threadripper 9000 "Shimada Peak" series is categorized into two processor model classes, the X-series for HEDTs, and the WX-series for workstations. The Threadripper 9000X series comes with 4-channel DDR5 (8 sub-channels) memory interface, along with 48 PCIe Gen 5 lanes from the processor, whereas the Threadripper PRO 9000WX series comes with 8-channel DDR5 (16 sub-channels) memory interface, along with 128 PCIe Gen 5 lanes.The Threadripper 9000X series targeting HEDTs comes in three SKUs, the 9980X with a 64-core/128-thread configuration with 3.20 GHz base frequency, up to 5.40 GHz boost, and 256 MB (8x 32 MB) L3 cache. This is followed by the 9970X, with its 32-core/64-thread configuration, 4.00 GHz base frequency, up to 5.40 GHz boost, and 128 MB (4x 32 MB) L3 cache. Lastly, there's the 9960X, with its 24-core/48-thread core-config, 4.20 GHz base frequency, up to 5.40 GHz boost, and the same 128 MB (8x 32 MB) L3 cache configuration as the 9970X. All three models come with a TDP of 350 W.The Threadripper PRO 9000WX family is more extensive, with six SKUs. All six boost up to 5.40 GHz, and come with 350 W rated TDP. The lineup is led by the Threadripper PRO 9995WX, with its 96-core/192-thread configuration, 2.50 GHz base frequency, and 384 MB (12x 32 MB) L3 cache. This is followed by the PRO 9985WX, with its 64-core/128-thread configuration, 3.20 GHz base frequency, and 256 MB (8x 32 MB) L3 cache. Next up, is the 9975WX with 32-core/64-thread config, 4.00 GHz base frequency, and 128 MB (4x 32 MB) L3 cache. Then there's the 9965WX with 24-core/48-thread, 4.20 GHz base frequency, and the same 128 MB L3 cache configuration as the 9975WX. Stepping below this is the 9955WX, with its 16-core/32-thread configuration, 4.50 GHz base frequency, and 64 MB (2x 32 MB) L3 cache. Lastly, there's the 9945WX, with its 12-core/24-thread configuration, 4.70 GHz base frequency, and 64 MB (2x 32 MB) L3 cache. The only reason anyone would opt for the 9955WX or 9945WX over desktop Ryzen 9 9000X series processors would be the 8-channel DDR5 and 128-lane PCIe Gen 5 I/O.
Both the 9000X and 9000WX share a common AMD Socket TR5 infrastructure, and when a Threadripper 9000X series processor is used on a motherboard with 8-channel memory and PCIe slots or onboard devices utilizing 128 lanes, half its DDR5 slots and some of those PCIe lanes will be disabled.

I don't understand this decision..
Three SKUs again, 9960X (24c), 9970X (32c) and 9980X (64c).

The 12-core Pro variant sounds interesting, and should also have been released as a non-Pro variant... where it'd have made even more sense.
They've had the final versions in testing since last year, when are they going to launch them? Absolutely, they need both more cut-down boards (without gimmicks) and boards that have the socket in the correct orientation for excellent air-coolers like Noctua NH-U14S TR5-SP6. Enthusiasts may want water coolers, but workstation users want reliability. If there is a market for a 12-core PRO variant, then there is certainly a market for a 12-core HEDT variant. I don't get why they keep repeating this mistake; A greatly priced 12-core Threadripper and some decent motherboards would sell like hot caces and be much more appealing than Ryzen 9 9900X to "prosumers".
(I say, while only having my 2x3090s that I bought out of my pocket :laugh:)
Hopefully those Epyc systems will be cheap enough in the used market.
My guess would be in the same ball park as the current lineup, hopefully a little lower.
Idly, it'd also be neat if they could have included 3D cache at least on the lower end too; if only to be able to pass-through a core complex alongside a GPU for offloading some light to moderate gaming over ethernet to a thin PC, or plainly just to have a gaming-capable hybrid build. But granted, such use cases are niche at the HEDT level.
