Intel could be bringing its 56-core CPUs to workstations

2 min read

In context: Intel initial declared the Sapphire Rapids line of Xeon processors in late 2019 and has introduced info about them at a trickle ever due to the fact. With up to 56 cores and in-bundle memory, they will be Intel’s most highly effective and huge processors to date.

Intel has been steadily updating the applicable organization software program in planning for Sapphire Rapids for more than a year. Some of that software program is open source and the supply of small leaks. Last 7 days, a trawler identified a reference to an unfamiliar processor in the boot log of a Linux kernel, the Intel W9-3495.

Very first, the name: Intel uses “W” for its workstation CPUs, for instance, the W-3375. It has not put quantities soon after the “W” nonetheless, so that could mean a several points, but it appears to be a large amount like the nomenclature utilised by the Core sequence — i5, i7, i9. It may well suggest the existence of related W7 or W5 CPUs with reduced core counts.

Next, the specs. The boot log suggests that the W9-3495 has 56 cores / 112 threads and a base clock of 1.8 GHz (that most likely is not ultimate). It lists AMX and AVX-512 guidelines as features of the CPU.

Nevertheless, it will not say regardless of whether or not the W9-3495 has the 64 GB of in-bundle HBM2e memory that Sapphire Rapids has garnered infamy for, and I would wager that it will never. It really is prohibitively costly, and also a thing that Intel would reserve for its flagship data middle processors as a providing place.

Intel’s workstation CPUs do ordinarily have most of the features of their server-aspect counterparts, even though. If the W9-3495 is no exception, then it will have eight lanes of DDR5 and a blend of PCIe 5. and PCIe 4. lanes summing to 80. It will unquestionably use the Willow Cove architecture and Intel 7 node (a rebrand of the 10nm Improved SuperFin Mouthful node) and the new LGA4677-X socket.

It will also be a mile above Intel’s current choices. Modern workstation flagship is the W-3375, which has only 38 cores / 76 threads and works by using the Ice Lake architecture from late 2019 and the very first-gen 10nm node. It truly is also trapped with DDR4 and PCIe 4.. It costs a whopping $4,499 – ouch – and is only truly readily available by way of OEMs, a fate that ideally the W9-3495 can keep away from.
