AMD video cards surpass Nvidia in Starfield thanks to architecture

When Starfield became available, many tests showed the superiority of AMD over NVIDIA equipment. Chipsandcheze decided to delve into the performance of Starfield and find out why the game works just like that. To get reliable results, Chipsandcheze analyzed the scene using NSight Graphics by NVIDIA and the Profilger of the Radeon Graphic Processor from AMD.

Chipsandcheze confirmed that in lower AMD Radeon RX 7900XTX resolutions, faster than NVIDIA GeForce RTX 4090. However, with a resolution of 4K, the high -performance NVIDIA graphic processor was able to reduce the gap.

This is mainly due to the architectural advantage of AMD (in this particular game) over the NVIDIA graphic processors. This has nothing to do with the drivers, the power of the NVIDIA graphic processors or something like that. NVIDIA graphic processors work exactly as they should, and everything is in order with them.

To simplify the task, as MikeReysalo explained to Reddit, AMD has chosen a smaller number of nuclei with large files of files for its graphic processors, which means that the graphic processor can track more flows into one core. Thus, in Starfield, this leads to an increase in filling.

On the other hand, Nvidia has chosen more nuclei with smaller file registers to use the advantages of parallelism. However, ultimately, this leads to a decrease in employment, and in this particular case, this can lead to a decrease in performance.

AMD also benefits from higher capacity of the L2 cache, since it has a smaller L2 cache. On the other hand, NVIDIA has a larger cache L2, but with less capacity.

In short, NVIDIA can not do anything to improve performance in this game. The only thing the green team was able to do is turn on Rebar, which brought a 5% performance increase. However, you should not expect any additional serious improvements in performance.
