The upcoming Intel Xeon 654 processor is an 18-core, 36-thread workstation CPU with 72MB of cache, and CPU clocks of up to 4.80GHz. We should expect the company to unveil two variants of its Granite Rapids-WS chips, with a 4-channel DDR5 memory version, and 8-channel "Expert" family. The mainstream Granite Rapids CPUs have 80 PCIe Gen5 lanes, while the Expert chips have 128 PCIe Gen5 lanes.

We will see Intel launch a much higher-end Granite Rapids-WS processor in the form of a beastly 86 cores and 172 threads, which was leaked a couple of months ago. The new Intel Xeon 654 processor with its 18C/36T was tested on a reference "GNR-WS" platform joined by 32GB of DDR5 memory.

Geekbench lists the Intel Xeon 654 processor with 18 cores, 36 threads, up to 4.60GHz clock speeds -- however actual clock speeds were closer to 4.80GHz -- 72MB of L3 cache, and 36MB of L2 cache. The single-core performance on Geekbench sat at 2634 points, with multi-core results reaching 14,743 points.
