Background on AMD Ryzen CPU
AMD's third generation of Ryzen processors offer more cores and higher clock speeds than previous models. Both of those improvements are enabled by use of multiple "chiplets" built on a 7nm process together with a larger 12nm IO die to tie them all together. In addition to architecture improvements, these processors also support faster memory - but the officially supported speeds depend on how many memory modules are used and whether they are single or double rank.

William George (Puget Labs Technician) Says:
This is almost exactly the same as AMD's Ryzen 9 3900X processor, just with 100MHz higher maximum boost speed. The practical impact of that is about 1-2% higher performance in most applications, which is almost impossible to notice without actually timing things... but since the price is the same, there is really no reason not to get this model if it is available.
