With RAMageddon causing people to look at older DDR4-based CPUs, I tested the 5700X3D with RTX4090 in 4 RT/PT games that I had played. With CapFrameX, I took multiple one-minute runs in CPU-limited areas and then aggregated them.

All RT/PT settings were enabled at 1080p w/ DLSS Ultra Performance with the latest driver. With CapFrameX, I took 3 one-minute runs in CPU-limited areas and then aggregated them.

Compared these to the results of 9800X3D from below thread.

Results : 9800X3D was 55-80% faster than 5700X3D. Cyberpunk was the best result, with 9800X3D only 55% faster, while Oblivion was the worst with 9800X3D 83% faster. 1% lows were more than twice as fast on 9800X3D in Oblivion and Jedi Survivor.
