Intel's plans for the workstation market with its Sapphire Rapids-WS are taking shape as a well-known hardware leaker published preliminary specifications for the new CPUs. Intel's lineup of next-generation Xeon products for workstations and high-end desktops will include overclockable CPUs with up to 56 cores, eight memory channels, and 112 PCIe lanes if the information revealed by reputable hardware leaker Enthusiastic Citizen (ECSM_Official) is correct. Intel's family of next-generation Xeon W processors for W790-based workstations will reportedly consist of two families of products that will offer slightly different capabilities. The Xeon W 3400-series CPUs will be derived from a multi-chiplet Sapphire Rapids design and will feature up to 56 cores, eight DDR5 memory channels, and 112 PCIe lanes. In addition, CPU cores used by these processors will be Golden Cove-derived cores with AVX-512 and AMX instructions enabled. By contrast, the Xeon W-2400-series processors will use a single-die design with up to 24 cores, four DDR5 memory channels, and 64 PCIe lanes. Intel's Xeon W-2400 and W3400-series processors are expected to come in LGA4677 packaging and use W790-based workstation motherboards. One of the first W790 mainboards leaked last week, which suggests that some of Intel's partners are getting ready to ship these products sooner rather than later. Meanwhile, a rumor suggests that Intel only intends to roll out its W790 platform next April, so it is too early to ship appropriate motherboards. Then again, Intel has never officially confirmed the launch timeframe for its W790 platform and only confirmed that this one is designed for workstations. Intel's Xeon W-3400-series lineup will allegedly include nine models, four of which will be overclockable. Even the flagship Xeon W9-3495X is expected to come with an unlocked multiplier making for overclocking support. Linux boot logs unearthed earlier this year essentially confirm the existence of Intel's Xeon W-3400-series CPUs (which come with AVX-512 and AMX enabled). Still, they also mention the Xeon W9-3495 (non-X) CPU clocked at 1.80 GHz base, which Enthusiastic Citizen does not list. We have no idea whether Intel changed its plans concerning its Sapphire Rapids-WS lineup in July, but we are dealing with preliminary information, so some details may be inaccurate. Intel's Xeon W-3400-series relies on Sapphire Rapids silicon, which will offer AVX-512 support and AMX instructions for artificial intelligence and machine learning applications. Advanced Matrix Extensions is a tiled matrix multiplication accelerator, a grid of fused multiply-add units supporting BF16 and INT8 input types that can be programmed using only 12 instructions and perform up to 1024 TMUL BF16 or 2048 TMUL INT8 operations per cycle per core.
