Starting at the top, the Xeon W-3400 series (Sapphire Rapids-112L) will vary from 12 to 56 cores, and all will include 112 PCIe 5.0 lanes, support for up to 4 TB of DDR5-4800 memory across eight memory channels, ECC memory (RDIMM-only), Intel vPro, and Intel Standard Manageability (ISM). Meanwhile compared to Intel’s existing desktop processor lineup, these are all features that were pioneered on Alder Lake (12 th Gen Core) back in late 2021, the workstation-focused Xeon W parts are going to be building things out to a much larger degree. All of which is a significant upgrade over the mix of Cascade Lake and Ice Lake parts that make up Intel’s previous product stack. Based on the same Sapphire Rapids silicon as Intel’s recently-launched server parts, the new Xeon W SKUs will bring down many (but not all) of the features that have come to define Intel’s leading-edge server silicon, along with a new chipset (W790) and motherboards that are more suitable for use in high-performance workstations.Īs with the new Xeon Scalable Parts, the big three additions here are the shift to Intel’s Golden Cove CPU architecture – with all the IPC and clockspeed benefits that brings – along with the addition of support for DDR5 memory and PCIe 5 for I/O connectivity. Aimed at what Intel is broadly classifying as the Expert Workstation and Mainstream Workstation markets respectively, these chip lineups are intended for use in high-performance desktop workstation setups, particularly those that require more CPU cores, more PCIe lanes, more memory bandwidth, or a combination of all three elements. This morning Intel is announcing their first top-to-bottom refresh of workstation parts, the Xeon W-3400 and Xeon W-2400 series. But now that Sapphire Rapids for servers has finally launched, the logjam in Intel’s product roadmap has at last cleared out, and Intel is finally in a position to resume cascading their latest silicon into new workstation parts.
Between the de facto retirement of Intel’s desktop-grade Xeon W-1x00-series lineup, and the repeated delays of Intel’s current-generation big silicon parts for servers, the Sapphire Rapids-based 4 th Generation Xeon Scalable series, there hasn’t been much noise from Intel in the workstation space in the last few years. For all of the singular focus that Intel has placed on its consumer Core desktop CPU parts in the last few years, you could be forgiven for thinking that Intel has forgotten about their Xeon premium processor lineups for workstations.
