Doom

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 7900 XT delivers a remarkably strong showing in Doom, with the measured data indicating that this combination is capable of high refresh rate play across all tested resolutions. The pairing of a 6-core, 12-thread Zen 3 CPU with a high-end RDNA 3.0 GPU produces results that are consistently smooth, though the choice of settings has a significant impact on the final frame rates.

Settings Recommendations

The benchmark results for this combination in Doom show a clear hierarchy across the four tested presets: Low, Medium, High, and Ultra. At 1920x1080, the Low preset achieves an average of 334.4 FPS, which represents the absolute ceiling for this pairing. However, this setting likely sacrifices visual fidelity for marginal gains. The Medium preset is the better recommendation for competitive play, as it delivers an average of 295.3 FPS, a substantial figure that is only 39.1 FPS lower than Low while offering improved image quality.

For those prioritizing visual quality without sacrificing the high-refresh experience, the High preset is the optimal choice. At 1920x1080, High produces an average of 251 FPS, which is still far beyond the refresh rate of most monitors. The Ultra preset, while visually demanding, still manages an average of 203.1 FPS at this resolution, indicating that even the highest settings remain playable. The data suggests that at 1080p, the GPU is so powerful that the CPU becomes the limiting factor, and the difference between presets is less pronounced than at higher resolutions.

At 2560x1440, the recommendations shift slightly. Here, the High preset is the clear winner for the best balance of performance and fidelity, delivering an average of 160.5 FPS. This is well above the 144Hz threshold, making it ideal for high-refresh 1440p monitors. The Medium preset offers a more substantial performance buffer at 190.6 FPS, but the drop in visual detail may not be worth the extra 30 FPS. The Ultra preset, at 134.6 FPS, is still viable, but it dips below the 144Hz mark, making High the more consistent choice for a smooth experience.

At 3840x2160, the data indicates that the High preset is again the best recommendation. It achieves an average of 89.3 FPS, which is the only 4K preset that stays comfortably above the 60 FPS playability threshold. The Medium preset reaches 104.7 FPS, but the visual difference between Medium and High is often significant, and the 15.4 FPS gain may not justify the loss of detail. The Ultra preset drops to 71.1 FPS, which is still playable but leaves less headroom for demanding scenes. For a stutter-free 4K experience, High is the definitive choice, while Low at 119.3 FPS is only for those who prioritize frame rate above all else.

GPU Role

The AMD Radeon RX 7900 XT is the dominant component in this pairing, and the benchmark results clearly show its influence. The GPU’s 20 GB of GDDR6 memory on a 320-bit bus provides a massive 800.0 GB/s of bandwidth, which is more than sufficient for Doom’s texture-heavy environments at any resolution. This memory capacity ensures that even at 4K Ultra settings, there is no risk of running out of VRAM, as the game's assets are easily accommodated.

The GPU’s clock speeds are also a key factor. With a base clock of 1387 MHz and a boost clock of 2394 MHz, the RDNA 3.0 architecture is able to maintain high frequency under load. The game clock of 2025 MHz is a more realistic indicator of sustained performance during gaming. The data shows that as resolution increases from 1920x1080 to 3840x2160, the average FPS drops by roughly 64% across all settings, which is a direct result of the GPU’s pixel and texture processing limits. The pixel rate of 459.6 GPixel/s and texture rate of 804.4 GTexel/s are the primary drivers of performance at higher resolutions.

Interestingly, the GPU’s role becomes more pronounced at higher resolutions. At 1920x1080 Low, the CPU is likely the bottleneck, as the 334.4 FPS figure is more dependent on the Ryzen 5 5600G’s single-thread performance. However, at 3840x2160 Ultra, the 71.1 FPS result shows the GPU is working near its limit, as the CPU has more time to feed it frames. The 84 ray tracing cores on the RX 7900 XT are not directly relevant to Doom, as this title does not use ray tracing, but they do not hinder performance either. The GPU’s 5376 shading units and 192 ROPs are the workhorses for this game’s rendering pipeline, and their efficiency is evident in the consistent frame rates.
