Doom

Resolution Scaling

The measured FPS data for Doom with the Intel Core i5-13400F and AMD Radeon RX 7600 XT reveals a clear pattern of GPU-bound performance scaling as resolution increases. At 1920x1080 with Ultra settings, the combo produces 120.3 FPS. Moving to 2560x1440 at the same preset drops this to 75.6 FPS, a reduction of 44.7 FPS. The jump to 3840x2160 Ultra yields 43.9 FPS, which is 31.7 FPS below the 1440p result and 76.4 FPS below the 1080p figure.

This scaling behavior indicates that the Radeon RX 7600 XT becomes the limiting component at higher resolutions. The GPU's 128-bit memory bus and 288.0 GB/s bandwidth constrain pixel throughput as the pixel count climbs. The CPU, with its 10 cores and 16 threads, is not the bottleneck here — even at 1080p Ultra, the frame rate of 120.3 FPS is well within what this processor can feed, given its Cinebench R23 multi-core score of 21279 and single-core score of 3004.

Looking at the Low preset across resolutions, the scaling steepens. At 1080p Low, the combo reaches 199.5 FPS. At 1440p Low, it drops to 131 FPS. At 4K Low, it falls to 67.8 FPS. The percentage drop from 1080p to 4K at Low settings is roughly 66%, whereas at Ultra settings the drop from 1080p to 4K is about 64%. This similarity suggests that even at lower settings, where the CPU could theoretically become more relevant, the GPU still dominates the frame time budget.

The Medium preset shows 176 FPS at 1080p, 110.5 FPS at 1440p, and 58.6 FPS at 4K. The High preset delivers 147.6 FPS at 1080p, 93.9 FPS at 1440p, and 48.6 FPS at 4K. Notably, the gap between 1440p and 4K is larger in absolute terms for the Medium and High presets than for Low, which further confirms that the GPU's fill rate and memory bandwidth are the primary constraints as resolution increases.

GPU Role

The AMD Radeon RX 7600 XT carries 16 GB of GDDR6 memory on a 128-bit bus, yielding 288.0 GB/s of bandwidth. Its boost clock reaches 2755 MHz, with a game clock of 2470 MHz and a base clock of 1980 MHz. The GPU's 2048 shading units and 64 ROPs produce a pixel rate of 176.3 GPixel/s and a texture rate of 352.6 GTexel/s. These specifications directly influence the measured frame rates in Doom.

At 4K Ultra, the combo averages 43.9 FPS. This is below the 60 FPS threshold that many users target, and it indicates that the GPU is working near its practical limit. The 16 GB VRAM allocation is more than sufficient for Doom's texture workloads, even at 4K Ultra, so memory capacity is not the limiting factor. Instead, the 128-bit bus width and the resulting 288.0 GB/s bandwidth restrict how quickly texture data can be streamed to the shading units.

The GPU's benchmark scores place it in context. Its PassMark G3D score is 17132, with a DirectX 11 score of 167 and a DirectX 12 score of 65. The Geekbench Vulkan score of 88301 and OpenCL score of 83114 show strong compute capabilities. Compared to its nearest rivals, the RX 7600 XT sits within 0.6% of the RX 7600 (which scores 20258), and 1.9% above the RTX 2060 SUPER (19774). The RX 460, at 20088, is 0.3% behind. These margins are small, meaning the 7600 XT's performance tier is well-established.

In Doom specifically, the GPU's role is most visible in the 4K results. The 4K Low preset produces 67.8 FPS, while 4K Medium produces 58.6 FPS, 4K High produces 48.6 FPS, and 4K Ultra produces 43.9 FPS. The progression from Low to Ultra at 4K shows a 23.9 FPS spread, which is a direct consequence of the GPU's shading and memory throughput limits. At 1080p, the same spread from Low (199.5 FPS) to Ultra (120.3 FPS) is 79.2 FPS, indicating that at lower resolutions the GPU has more headroom and the settings have a larger relative impact.

In absolute terms, the combo's rank of 1115 out of 1681 means it is not positioned for top-tier performance in Doom. The measured FPS at 1080p Ultra (120.3 FPS) is respectable, but at 4K Ultra (43.9 FPS) it falls below the standard 60 FPS target. Users seeking higher 4K performance would need a GPU with more bandwidth and shading throughput, as the data shows the CPU is not the limiting factor.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and frame rate goal. For 1080p, the Ultra preset delivers 120.3 FPS, which is above 120 FPS and suitable for smooth gameplay on most monitors. The High preset at 1080p yields 147.6 FPS, offering a 27.3 FPS improvement over Ultra while still maintaining high visual quality. For users prioritizing frame rate over fidelity, the Low preset at 1080p reaches 199.5 FPS, which is near the 200 FPS mark.

At 1440p, the High preset provides 93.9 FPS, which is close to 100 FPS and offers a good balance. The Medium preset gives 110.5 FPS, while Ultra drops to 75.6 FPS. The Low preset at 1440p hits 131 FPS, but the visual trade-off may not be worth it for a game like Doom. The data suggests that 1440p High is the sweet spot, as it stays above 90 FPS while maintaining reasonable quality.

For 4K, the situation is more constrained. The Low preset averages 67.8 FPS, which is the only 4K setting that clears 60 FPS. The Medium preset at 58.6 FPS is borderline, and the High preset at 48.6 FPS and Ultra at 43.9 FPS both fall well short of 60 FPS. If 4K is the target, the Low preset is the only measured option that provides a consistently playable frame rate. Otherwise, dropping to 1440p with High or Ultra settings will yield a better experience.
