AMD Threadripper 9000 “Shimada Peak” Workstation CPUs to Include 12-Core Model; New SKUs Found in Shipping Documents

Shipping records have recently shed light on the upcoming AMD Zen5-based Threadripper “Shimada Peak”CPUs, showcasing a range of variants including 64-core, 16-core, and an intriguing 12-core model. This revelation highlights AMD’s commitment to diversification in their server CPU offerings.

Overview of AMD’s Shimada Peak CPUs: A New Era Begins

AMD has yet to debut the Zen5 architecture within its Threadripper and Threadripper Pro lines, and information regarding this upcoming series remains somewhat limited. However, our current understanding identifies the Threadripper 9000 series as “Shimada Peak”.Notably, details have emerged regarding a flagship model boasting an impressive 96 cores, alongside additional information surfaced through shipping manifests, courtesy of @Olrak_29.

New Variants in the Threadripper 9000 Lineup

The shipping manifests disclose three significant models within the Threadripper 9000 series. First is the 64-core Ryzen Threadripper 9985WX. We have encountered this model previously, though specific details like clock speeds remain undisclosed. It’s anticipated to utilize an octa-CCD (Chiplet Die) layout, with each CCD housing an 8-core configuration. Additionally, this model will have a thermal design power (TDP) rated at 350W, showing incremental improvements over its predecessor, the Threadripper 7985WX.

Moving on, the Threadripper 9955WX emerges as a 16-core variant tailored for entry to mid-range workloads, featuring a dual-CCD layout, a substantial 64 MB of L3 cache, and a similar 350W TDP. The most noteworthy addition is the Threadripper 9945WX, introducing a unique 12-core configuration for the first time in this series. This model is designed with a potential configuration of four CCDs, each containing three cores, while also maintaining the 350W TDP rating.

A Comprehensive Product Lineup on the Horizon

The Threadripper 9000 series is set to feature an extensive array of configurations, including 12, 16, 24, 32, 64, and the flagship 96-core offerings. Both the Threadripper 9000 and PRO 9000 WeUs are scheduled to support the TRX50 and WRX90 chipsets, respectively, and rumors suggest they may integrate 3D V-Cache technology, though specifics remain uncertain. Expect formal announcements during Computex, with an official launch anticipated in the second half of 2025.
