Intel hasn't issued a press release on the launch, but it did update its ARK page with listings for nine new Xeon W 3000 series processors, which run the gamut from 8 cores and 16 threads all the way up to 28 cores and 56 threads.
Cascade Lake W represents a further refinement to the manufacturing process—the new chips are built on a 14nm++ node, whereas Skylake W featured a 14nm+ node. This paves the way for more cores (and threads) to throw at workloads. The other difference is the socket. Previous generation Skylake W Xeon processors used the aging LGA 2066 socket, whereas the Cascade Lake W parts slip into socket LGA 3647 motherboards.
What the new generation of Xeon chips bring to the table is essentially a doubling of the core and thread counts. Instead of starting at 4 cores and 8 threads like Skylake W, the new Cascade Lake W chips start at 8 cores and 16 threads. Here's a look at the lineup...

These chips also feature beefier memory channel support. Cascade Lake W in non-M form supports up to 1TB of DDR4 RAM in a six-channel memory arrangement, at speeds of up to 2,933MHz. The M variants, which cost more, support up to 2TB of RAM.
