The 2950X and 2990WX are both ThreadRipper 2 chips but are very different beasts under the hood.  The 2950X has two active die similar to the original chips while the 2990WX has four active die, two of which utilize an Infinity Fabric link to the other two to communicate to the memory subsystem.  The W in the naming convention indicates the 2990WX is designed for workstation tasks and benchmarks support that designation.  You will have seen our results here, but there are many other sources to read through.  [H]ard|OCP offers up a different set of benchmarks in their review, with a similar result; with ThreadRipper AMD has a winner.  The 2990WX is especially important as it opens up the lucrative lower cost workstations market for AMD.

"AMD teased us a bit last week by showing off its new 2nd Generation Threadripper 2990WX and 2950X packaging and specifications. This week AMD lets us share all our Threadripper data we have been collecting. The 2990WX is likely a lot different part than many people were expecting, and it turns out that it might usher AMD into a newly created market."
