May 26, 20242 yr Looking to build a completely new system. I've been following the intel vs amd in recent times, but I still can't get past one thing. Everyone seems to be recommending the 7800x3d (L3 etc.) at 4.2 base up to 5.0 ghz. The 7950x3d is at 4.2 base up to 5.7 ghz. I know the old adage was the higher the clock speed the better the performance. So it would seem the 7950x3d is the answer. Is there any upside to the 7800x3d over the 7950x3d other than price (not an issue)? Evan Hardin
May 27, 20242 yr In some game benchmarks the 7800X3D score very slightly better. But just within some %. And for most games it is equal (or the other way around). What I've seen often is that 7900X3D is behind 7800X3D and 7950X3D. This site https://www.notebookcheck.com/AMD-Ryzen-9-7950X3D-Desktop-CPU-im-Test-Neues-Gaming-Flaggschiff-mit-3D-V-Cache-auf-Sockel-AM5.704003.0.html (German) still runs the X-Plane 11.11 tests for example. https://imgur.com/IKbmBoo My theory is that having some load on the other cores let's you not reach the advertised max. speed even with very good cooling.
