VideoCardz (opens in new tab) has posted the potential specs for Intel’s upcoming Sapphire Rapids-WS processors. Nonetheless, it is essential to focus on that these core-heavy chips goal the workstation demographic, not like Sapphire Rapids-SP, which caters to knowledge facilities.
Sapphire Rapids makes use of the identical Intel 7 (rebranded 10nm Enhanced SuperFin) course of and Golden Cove cores as Intel’s mainstream Alder Lake lineup. The unique plan for Sapphire Rapids was to compete in opposition to AMD’s EPYC 7003 (Milan) processors. Nonetheless, Sapphire Rapids has suffered a number of delays and, by how issues look, will possible find yourself taking over the Zen 4-powered EPYC 9003 (Genoa) lineup. Then again, Sapphire Rapids-WS targets Crew Pink’s Ryzen Threadripper Professional 5000 WX-series (Chagall) military. The Zen 3-powered processors are on TSMC’s 7nm FinFET course of, whereas Sapphire Rapids is a product of a 10nm course of node.
In accordance with the doc that VideoCardz obtained, which the publication did not share, Sapphire Rapids-WS help DDR5-4800 reminiscence natively. The 10nm chips solely help 1S configurations. The doc reportedly did not affirm the variety of reminiscence slots or PCIe 5.0 lanes. Nonetheless, Sapphire Fast-WS allegedly comes with 8-channel help and 112 PCIe 5.0 lanes. If comparability, Chagall remains to be on DDR4 reminiscence and presents 128 PCIe 4.0 lanes.

*Specs are unconfirmed.
Sapphire Rapids-WS retain the identical hierarchy as Intel’s mainstream chips, however logically, substituted the Core branding for the Xeon moniker. Due to this fact, the stack consists of the W9, W7, and W5 SKUs. As at all times, we must always deal with the specs with warning since Sapphire Rapids-WS is unreleased {hardware} and we do not know they state of the workstation processors.
The Xeon W9-3495X, one of many high SKUs, wields 56 cores, 112 threads and 105MB of L3 cache. The chip reportedly has a 1.9 GHz clock pace with a 350W TDP. It is nonetheless just a few steps behind Ryzen Threadripper, although. For comparability, the Ryzen Threadripper Professional 5995WX has 64 cores, 128 threads and 256MB of L3 cache. AMD’s chip has a 280W TDP. which is decrease than the Xeon W9-3495X.
The W7 tier embrace SKUs with core counts spanning from 20 to twenty-eight Golden Cove cores. The L3 cache varies from 52.5MB to 75W with TDP ranges between 270W and 300W. The W5 class. for instance, homes chips with 12 to 16 cores. The L3 cache is extra modest with elements sporting 30MB as much as 45MB. The TDP for the Xeon W5-series ranges from 200W to 270W.
It is unknown when Sapphire Rapids-WS processors will hit the retail market. AMD’s newest desktop processor roadmap reveals the chipmaker’s plans to deliver its Zen 4 cores over to the Ryzen Threadripper household subsequent 12 months. Sapphire Rapids-WS will face some powerful competitors forward.
