Intel Releases Xeon-W Processors For Workstations
Intel today disclosed that the performance of the Intel Xeon Scalable processors is now available for next-generation workstations.
The new processors are designed to power professional workstations used for creation of 3D VR content, ultrahigh-definition (HD), 3D content or AI analytics.
Unveiled in July 2017, Intel Xeon Scalable processors deliver breakthrough dual-socket performance, offering up to 56 cores, up to 112 threads and an Intel Turbo Boost Technology frequency up to 4.2 GHz. Expert workstations will experience up to a 2.71x boost in performance compared to a 4-year-old system and up to 1.65x higher performance compared to the previous generation, according to Intel.
The single-socket Intel Xeon W processor delivers mainstream performance optimized for the needs of traditional workstation professionals. The Intel Xeon W processor features up to 18 cores and up to 36 threads, with an Intel Turbo Boost Technology frequency up to 4.5 GHz. Mainstream workstations will experience up to a 1.87x boost in performance compared to a 4-year-old system and up to 1.38x higher performance compared to the previous generation.
As a replacement for the E5-1600 series, the Xeon-W CPUs will feature parts from 4 cores up to 18 cores, support up to 512GB of ECC RDIMM/LRDIMM memory, support dual 512-bit FMAs throughout the stack, and peak turbo clocks of 4.5 GHz.

In essence, these are Xeon versions of the current Skylake-X (Core i9) processors with all the pro features enabled, such as the extended memory support, vPro, Intel's AMT, and the standard enterprise Reliability, Serviceability and Availability (RAS) features. They will require a new chipset, the C422 chipset, and despite the common LGA2066 socket, it seems unlikely that this will work with the consumer X299 chipset.
All the parts will support 48 PCIe 3.0 lanes from the processor, suitable for 2x GPU and 3x PCIe storage direct from the CPU without going out to the chipset. Every processor in the Xeon-W stack sits at 140W, except the quad cores at 120W. By contrast, Skylake-X goes up to 165W. It is also worth noting that the Xeon-W processors only support Turbo Boost 2.0 rather than Turbo Boost Max 3.0. And as with past Xeon processors, Xeon-W processors are also likely to be locked.
There are several obvious comparisons that can be made between the Xeon-W family and both the consumer Skylake-X and the server Xeon-SP platforms. Intel's goal here is to hit something in the middle: an increase in price over Skylake-X gets you more memory support, ECC, more PCIe lanes, and management features, but doesn't go the full way to six-channels of DDR4 or multi-socket support.
