To put that in perspective, the "lesser" Ryzen Threadripper 1920X debuted with an MSRP of $799. The same processor is currently selling for $668 on Amazon, but for the extra $50, it'd probably be prudent to just push the pedal the metal and go for the flagship processor. Amazon's deal on the Ryzen Threadripper 1950X is for a limited time only and will expire April 27th at 3AM EST (or while supplies last).
The Ryzen Threadripper 1950X has 16 physical cores and is capable of executing 32 threads. The HEDT processor features a base clock of 3.4GHz and all-core boost frequency of 3.7GHz. The Ryzen Threadripper 1950X can boost up to 4.0GHz on four cores and has an XFR frequency of 4.2GHz on four cores.
The Ryzen Threadripper 1950X's most direct competition is the Intel Core i9-7960X "Core X-Series" HEDT processor. The Core i9-7960X, like the Threadripper 1950X, has 16 physical cores (32 threads) and is aimed at the HEDT market. However, Intel's offering is priced at a whopping $1,564 at Amazon against an MSRP of $1,699. To put that in perspective, that's over twice the price of a single Ryzen Threadripper 1950X. That's a heck of a gap in pricing, and would go a long way towards paying for 32GB of DDR4 memory and X399 motherboard.
