Intel Xeon W "Sapphire Rapids" Workstation Processor Lineup Leaked
Ahead of its launch, the SKU table of Intel's Xeon W "Sapphire Rapids" HEDT/Workstation-class processor lineup was leaked to the web. The lineup is horizontally split between the Xeon W-3400 series, and the Xeon W-2400 series. The W-2400 series come in rather modest CPU core-counts ranging between 6-core/12-thread and 24-core/48-thread. These chips are characterized by a 4-channel DDR5 memory interface (8 sub-channels); and a 64-lane PCIe Gen 5 I/O. The W-3400 series, on the other hand, ranges between 12-core/24-thread and 56-core/112-thread, nearly maxing out the core-count of the "Sapphire Rapids" MCM. These chips feature a massive 8-channel (16 sub-channel) DDR5 memory interface, and a 112-lane PCIe Gen 5 I/O. Prices for the lineup start at a surprisingly low $360 for the base W-2400 series SKU; while the top W-2400 series SKU is priced at $2,189. The W-3400 series ranges between $1,189 for the base 12-core/24-thread part, and goes all the way up to $5,889 for the top 56-core part. All models feature ECC memory support.

Workstation class chips with ECC, eight channel DDR5 support, four to five times the PCIe lanes, and other accelerators are indeed great value for these prices.
Edit: Looks priced competitively against Ryzen Threadripper Pro 5000 series and equivalent core count Zen 4 Epyc 1P products. But its gotta kill Intel that they were able to sell 28 core Cascade Lake Xeon W’s for $7,453 back in 2019.
For actual use. w5-3435X - $1589 is a good choice. It will still OC "some" and probably match a stock 13900K, but also has 112 PCIe 5 lanes. That's the important part here.
Intel has a lot to prove - mainly in the efficiency department.
The W5-3425 looks promising with 8-channel RAM at that price, could be a decent base for large-dataset GPU compute nodes.
