Doom

Resolution Scaling

The benchmark data for Doom with the AMD Ryzen 5 7600 and AMD Radeon RX 7800 XT reveals a clear progression of performance as resolution increases, with the game remaining highly playable even at the most demanding settings. At 1920x1080 with Low settings, the combo delivers an average of 279.9 FPS. Moving to 2560x1440 with the same settings drops this to 180.7 FPS, a reduction of roughly 35%. At 3840x2160 with Low settings, the average falls to 100.8 FPS, which is about 64% lower than the 1080p result. This pattern shows that the GPU is the dominant scaling factor, as the frame rate penalty from increasing pixel count is substantial.

The scaling behavior across settings tells a more nuanced story. At High settings, the frame rate drops from 206.9 FPS at 1080p to 133.5 FPS at 1440p, then to 72.2 FPS at 4K. The percentage drop from 1440p to 4K is roughly 46%, which is steeper than the drop from 1080p to 1440p at about 35%. This suggests that at 4K, the RX 7800 XT is increasingly bound by its raw rendering throughput, with the memory bandwidth of 624.1 GB/s and the 256-bit bus becoming more critical. The data indicates that the CPU, with its 6 cores and 12 threads, has ample headroom at lower resolutions, but the GPU’s pixel rate of 233.3 GPixel/s becomes the limiting factor as resolution climbs.

At Ultra settings, the scaling is even more pronounced. The 1080p average is 167.4 FPS, dropping to 110.1 FPS at 1440p and 57.8 FPS at 4K. The 4K Ultra result is only 34.5% of the 1080p Ultra figure, showing that the most demanding preset imposes a severe penalty at high resolutions. This indicates that the combination of higher pixel count and the additional graphical workload of Ultra settings saturates the GPU’s capabilities. The data strongly suggests that for 4K gaming, users should consider Medium or High settings to maintain smooth frame rates, as the jump from High to Ultra at 4K costs 14.4 FPS, a 20% reduction.

The data shows that the GPU is the limiting factor at higher resolutions. At 1080p, the frame rates are high enough that the CPU may have some impact, but as resolution increases, the GPU’s rendering workload dominates. The pixel rate of 233.3 GPixel/s and texture rate of 583.2 GTexel/s are critical for filling the screen at 4K, and the performance drop from 1080p to 4K at any given setting highlights the GPU’s role. The 16 GB VRAM is more than sufficient for Doom’s requirements, and the memory bandwidth ensures that texture streaming is not a bottleneck. Overall, the RX 7800 XT provides excellent performance for this game, with the caveat that Ultra settings at 4K push it to its limits.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user’s resolution and frame rate targets. For 1920x1080, all settings presets deliver well above 100 FPS, with even Ultra averaging 167.4 FPS. This means that gamers with 1080p displays can confidently select Ultra settings for the best visual quality without sacrificing smoothness. The High preset at 206.9 FPS offers a good balance, but the data shows no reason to compromise at this resolution.

At 2560x1440, the Ultra preset averages 110.1 FPS, which is still excellent for most monitors. However, users with high-refresh-rate displays (144 Hz or above) may prefer the High preset at 133.5 FPS or even Medium at 160.5 FPS to maximize frame rates. The difference between High and Ultra at 1440p is 23.4 FPS, which is a noticeable improvement for competitive play. For the best balance of visual quality and performance, the High setting at 1440p is recommended, as it maintains a strong frame rate while offering superior graphics compared to Medium.
