VideoCardz has provided the Sapphire Rapids-WS CPU specs. These core-heavy chips target workstations, not data centers, unlike Sapphire Rapids-SP.
Sapphire Rapids uses Intel's standard Alder Lake technology with Golden Cove cores. Sapphire Rapids was designed to compete with AMD's EPYC 7003 (Milan) CPUs. Sapphire Rapids has been delayed numerous times and will likely compete with the EPYC 9003 (Genoa) lineup. Sapphire Rapids-WS targets Team Red's Ryzen Threadripper WX-series (Chagall). Zen 3-powered processors are 7nm FinFET, whereas Sapphire Rapids is 10nm.
According to a document VideoCardz got, Sapphire Rapids-WS support DDR5-4800 natively. 10nm chips are 1S-only. The paper didn't confirm memory slots or PCIe 5.0 lanes. Sapphire Rapid-WS has 8-channel support and 112 PCIe 5.0 lanes. Chagall has 128 PCIe 4.0 lanes and DDR4 RAM. The Xeon W9-3495X has 56 cores, 112 threads, and 105MB of L3 cache. The processor is 1.9 GHz and 350W. Still behind Ryzen Threadripper. Ryzen Threadripper Pro 5995WX features 64 cores, 128 threads, and 256MB L3 cache. AMD's processor has a lower TDP than Xeon W9-3495X (280W).
The specs of course, remain unconfirmed.
