The latest details on the refreshed Xeon Workstation CPUs come from SKYWALKERAMD at Hwbot who has shared the full-on test results of both the Xeon W9-3575X and the Xeon W7-2595X CPUs. Let's start with the specifications, the Xeon W9-3575X is a 44-core chip with 88 threads, a clock of 2.2 GHz base and 4.6 GHz boost, 97.50 MB of L3 cache, and 88 MB of L2 cache. The chip features a TDP of 340W and also gets 8-channel memory support, demonstrated by the eight 32 GB memory modules (DDR5-7000), the chip was tested with. The CPU was tested on the ASUS PRO WS W790E-SAGE SE motherboard.

The second chip to be tested is the Xeon W7-2595X CPU which is a 26-core part with 52 threads, a clock speed of 2.8 GHz base, and 4.8 GHz boost, 48.75 MB of L3 cache, and 52 MB of L2 cache. This CPU is configured with a 250W TDP and was running quad-channel memory with four 16 GB sticks clocked at DDR5-6000 on the ASUS PRO WS W790-ACE motherboard.

Compared to their predecessors, the Xeon W9-3575X CPU offers 8 additional cores, 16 additional threads, 15 MB more L3 cache, and slightly lower clock speeds which can be attributed to the ES nature of this chip. For the Xeon W7-2595X, you will get 2 additional cores, 2 additional threads, and a 3.75 MB
