AMD Zen5-based Threadripper "Shimada Peak" CPUs have been spotted in shipping manifests, revealing 64-core, 16-core, and 12-core variants.
AMD's Shimada Peak CPUs to Feature An Extensive Range of SKUs, Including a Surprising 12-Core Model
Well, in the server CPU segment, Team Red has yet to integrate their Zen5 architecture into Threadripper and Threadripper Pro series CPUs, and interestingly, details about AMD's next lineup are confined. Based on what we know now, it is claimed that the Threadripper 9000 series is to be labeled as "Shimada Peak", and we did get some information about the flagship offering in the lineup, coming in with 96 cores, and now, shipping manifests have revealed details (via @Olrak_29) about new variants as well.
The manifests have revealed three new variants, starting with the 64-core Ryzen Threadripper 9985WX. We have seen this particular model in the past, and while we are unaware of the specifics, such as clock speeds, the Threadripper 9985WX would likely feature an eight CCD layout. given that each CCD will hold an 8-core configuration. The TDP for this model is set to be at 350W, and when it comes to the previous-generation Threadripper 7985WX counterpart, there isn't much of a difference apart from the architectural advantage.
Next up is the Threadripper 9955WX, a 16-core model, an entry-level SKU likely designed for low-to-mid-intensity workloads. This version will use a dual-CCD layout, 64 MB of L3 cache, and a 350W TDP. The last is rather a new model, the Threadripper 9945WX, which is said to feature a 12-core configuration, and this is the first time we have seen this configuration surface up in Shimada Peak. As for the CCD layout might be configured as four CCDs with three cores each, and as for the TDP, this model is also rated at 350W.
So far, the Threadripper 9000 series is said to come in 12,16, 24, 32, 64 and 96 core configurations, so the lineup will be extensive. Both the Threadripper 9000 and PRO 9000 SKUs are expected to launch on the same TRX50 and WRX90 chipsets, respectively, and are also rumored to feature 3D V-Cache technology, although we aren't certain much about it. As for the release date, we can expect an announcement at Computex, with the official unveiling coming in H2 2025.
