amd ryzen 9 7900x3d gaming cpu

I feel a little bad for the AMD Ryzen 9 7900X3D. This 12-core 3D V-Cache processor sits in the middle of the 8-core Ryzen 7 7800X3D (that ranks as thefastest gaming processor) and the 16-core Ryzen 9 7950X3D (that combines excellent gaming and content creation performance).

Get the Ryzen 9 7900X3D 12-core processor for $439 (was $510, MSRP $599)

It’s a sensible system that works well, although on occasion we see worse gaming performance than the simpler 7800X3D, which has just one chiplet with the 3D-Vache, so there’s no extra software component. Inmy testing for Digital Foundry, that happened in just a handful of games, so the 7900X3D is still a reliable performer that is significantly faster in games than thealready-impressive 7900X.

Otherwise, the only deficit here is that as the 7900X3D uses six cores from each chiplet, you have a smaller number of V-Cache enabled cores than the two other X3D chips, resulting in slightly lower performance in games that use up that many cores (normally between 5 and 15%). However, what you lose in terms of gaming performance versus the 7800X3D you more than make up for in improved multi-threaded performance, on account of having 50% more cores and threads - and that translates into a strong advantage in any task that can be run in parallel, from transcoding video to 3D rendering and compiling programs.

In short then, do consider the 7900X3D - especially at this reduced price.
