AMD Launches 8-Core/16-Thread Ryzen Threadripper 1900X

A month ago AMD announced a third Ryzen Threadripper and today the 1900X has launched. This is an 8-core/16-thread HEDT CPU and has an MSRP of $549, which would make it more expensive than the 8-core/16-thread Ryzen 7 CPUs, but it has Threadriprer features the less expensive chips do not. For starters, the 1900X has 64 PCIe 3.0 lanes off of the chip, with 60 available for peripherals (the other four are reserved for the chipset). It also supports quad-channel memory and up to eight DIMM slots. The 1900X does have a higher base clock of 3.8 GHz than the higher core count 1920X (3.5 GHz) and 1950X (3.4 GHz) though, and a higher all-core boost of 3.9 GHz instead of 3.7 GHz.

The purpose of the 1900X is for content creators not wanting to or unable to spend the $799+ for the higher end CPUs, and not for people just looking to game. For that the Ryzen 7/5/3 processors are still what AMD recommends, and if you look at the source you will even find a graph that shows the R7 1800X beating the 1900X is a number of games. This difference in performance might be related to the different internal topologies. The Ryzen 7 chips are all comprised of two CCXes on a single die while the 1900X contains two dies with only one active CCX on each. That means communication from one 4-core/8-thread CCX to the other has a higher latency. You get higher inter-CCX latency but also more PCIe 3.0 lanes, more DIMM slots, and four DDR4 channels instead of two. Really comes down to what your expected workload will be.

i was doing some comparison this morning and quickly realized that the 1900x and i7-7820 are very similar quality and features wise...180watts versus 140watts means more heat heat for the 1900x but the bonus is the increased base clock....but the more i look at them the more i like to see a working comparison...
