Intel Xeon W-3200 Cascade Lake processors have been announced following up on Intel's Xeon W-2100 Skylake Lake processors.

Intel Cascade Lake Xeon W-3200 Launched: Server Socket, 64 PCIe 3.0 lanes

The new Cascade Lake-based Xeon W-3200 family will be offered up to 28 cores, using Intel’s XCC 28-core die as the base for the high-end models. As a Cascade Lake processor, the new Xeon W will come with additional in-hardware fixes for some of the Spectre and Meltdown vulnerabilities, similar to the Cascade Lake Xeon Scalable Processors. Intel has also made a substantial change in the way that it intends to market its Xeon W processors, as the new models also change socket compared to the previous generation.

Historically we are afforded multiple generations of workstation CPU on the same socket, however at this time Intel has decided to forgo this application and move Xeon W from the LGA2066 socket to the LGA3647 socket, limiting users who wish to upgrade from their Xeon W-2100 processors. The new socket, combined with the new silicon, means that Intel can offer new Xeon W owners more features, although much to the chagrin of previous Xeon W owners. This doesn't exclude Intel launching another set of CPUs on the LGA2066 socket for upgrades, however given the lack of fanfare for this launch, it wouldn't seem likely that Intel has plans to do so.

The LGA3647 socket has been used in Xeon Scalable processors since Skylake-SP launch, and affords six full DDR4 memory channels. The silicon inside the new Xeon W does have six memory controllers, allowing it to take full use of this feature. (Technically the previous generation also had six memory controllers in the silicon, but the platform was limited to four, as per Intel’s product positioning strategy.)
