AMD Ryzen 9 7950X3D Slower than the Intel Core i5-13600K in Starfield, Core i9-13900K Much Faster

We recently tested Starfield across NVIDIA and AMD’s fastest GPUs and found it to be a fairly optimized title that runs considerably better on Radeon hardware. Surprisingly, the CPU performance paints a different picture. Being an AMD partner title, you’d expect Ryzen chips, most notably the 7000X3Ds, to run exceptionally well in Starfield. However, the Ryzen 7 7800X3D and R9 7950X3D are both beaten by a cheaper Intel part, the Core i5-13600K.

The Radeon RX 7900 XTX costs $600 less and is mostly slower than the GeForce RTX 4090, but both GPUs perform roughly the same in Starfield. However, when paired with the former, the Ryzen 7 7800X3D falls behind the Core i5-13600K, with the Ryzen 9 7950X3D running just as well as the Core i5-12600K. Meanwhile, the Core i9-13900K is the fastest CPU on the block, with a lead of over 26% over the 7800X3D.

The Zen 4 X3D CPUs had scheduler issues at launch wherein the application would use threads from both CCDs (V-Cache and planar), degrading gaming performance. However, a game from an AMD partner several months after the latest X3D release should be well-optimized for these chips. For the 7950X3D, the issue turned out to be the Xbox Game Bar. Apparently, it doesn’t detect Starfield as a game and must be manually added. This improves performance on the multi-die X3D chips, but the 5800X3D and 7800X3D leave much to be desired.
