Doom

The AMD Ryzen 7 5800X3D paired with the AMD Radeon RX 7600 XT delivers a robust performance profile in Doom, with the data indicating a system that scales predictably across resolutions. The benchmark results show a clear transition from CPU-bound behavior at lower resolutions to GPU-bound behavior at 4K, with the GPU's 16 GB of VRAM providing ample headroom for the game's texture demands.

Resolution Scaling

The measured FPS data reveals a steep performance gradient as resolution increases. At 1920x1080 with Low settings, the combo achieves 203.1 FPS, which drops to 131.7 FPS at 2560x1440 and further to 71.9 FPS at 3840x2160. This represents a 35% decline when moving from 1080p to 1440p at Low settings, and a 45% decline from 1440p to 4K. The pattern indicates that at 1080p, the CPU's 8 cores and 16 threads are sufficient to feed the GPU, but the rendering load scales heavily with pixel count.

The scaling behavior shifts with higher settings. At Ultra settings, the frame rate drops from 118.6 FPS at 1080p to 79.1 FPS at 1440p (a 33% reduction) and then to 42.7 FPS at 4K (a 46% reduction from 1440p). The consistency of these percentage drops across settings suggests the rendering pipeline is uniformly stressed by resolution, rather than any single bottleneck emerging at specific quality levels.

The gap between Low and Ultra settings widens with resolution. At 1080p, Low is 84.5 FPS faster than Ultra (203.1 vs 118.6). At 4K, this gap narrows to 29.2 FPS (71.9 vs 42.7). This compression indicates that at higher resolutions, the GPU's compute resources become the limiting factor, reducing the relative impact of quality settings.

GPU Role

The Radeon RX 7600 XT is built on the RDNA 3.0 architecture with a Navi 33 chip, featuring 2048 shading units and 64 ROPs. Its clock speeds are substantial: a base clock of 1980 MHz, a game clock of 2470 MHz, and a boost clock of 2755 MHz. The memory subsystem provides 16 GB of GDDR6 on a 128-bit bus, yielding a bandwidth of 288.0 GB/s. This bandwidth is critical for Doom's texture streaming, and the 16 GB capacity ensures that even at 4K Ultra settings, the GPU does not resort to memory compression or swapping.

The GPU's pixel rate of 176.3 GPixel/s and texture rate of 352.6 GTexel/s directly influence the measured frame rates. At 4K Ultra, the system produces 42.7 FPS, which aligns with the GPU's compute throughput given the game's demands. The FP32 performance of 22.57 TFLOPS provides the raw compute necessary for the game's lighting and particle effects, though the data suggests this becomes the primary constraint at higher resolutions.

The GPU's nearest rival data shows it sits close to the AMD Radeon RX 7600, with a deltaPct of -0.6, indicating the XT variant offers marginal performance gain. Against the NVIDIA GeForce RTX 2060 SUPER, the RX 7600 XT holds a 1.9% advantage in average benchmark score. These small deltas suggest the GPU's performance class is well-matched to the CPU's capabilities, avoiding a significant imbalance in this combo.

How This Combo Ranks

In the database of tested combinations, this pairing of Ryzen 7 5800X3D and Radeon RX 7600 XT ranks 1068 out of 1681 combos for Doom. This places it in the 63rd percentile of all tested systems, indicating a mid-to-upper tier position. The CPU's percentileVsAllCpus of 83 is notably higher than the GPU's percentileVsAllGpus of 63, suggesting the processor has more headroom than the graphics card in this configuration.

The CPU's average benchmark score of 26574 places it within 0.4% of the AMD EPYC 8024P and Intel Core i9-11900K, with deltaPct values of 0.1 for both. This tight clustering indicates the 5800X3D's performance is competitive with these alternatives, though the 3D V-Cache technology (96 MB shared L3) is designed to excel in gaming workloads specifically. The GPU's average score of 20146 is within 1.9% of the RTX 2060 SUPER, showing the graphics card performs at a similar level to that older but capable competitor.

The rank of 1068 out of 1681 suggests that while this combo is not at the top tier, it is firmly in the upper half of tested systems. The combination of a high-percentile CPU with a mid-tier GPU creates a system where the processor is unlikely to bottleneck, allowing the GPU to operate at its full potential in Doom.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce 203.1 FPS, Medium settings yield 172.4 FPS, High settings achieve 145.1 FPS, and Ultra settings result in 118.6 FPS. The performance headroom at this resolution suggests the CPU is capable of driving higher frame rates, but the GPU's rendering limits become apparent as settings increase.

Moving to 2560x1440, the frame rates decrease proportionally. Low settings maintain 131.7 FPS, Medium settings drop to 113.9 FPS, High settings produce 92.9 FPS, and Ultra settings yield 79.1 FPS. The gap between Low and Ultra narrows to 52.6 FPS, compared to 84.5 FPS at 1080p, indicating the GPU is becoming more stressed.

At 3840x2160, the system operates at its lowest performance tier. Low settings achieve 71.9 FPS, Medium settings produce 61.9 FPS, High settings deliver 52.4 FPS, and Ultra settings result in 42.7 FPS. The difference between Low and Ultra is 29.2 FPS, showing that even at 4K, the GPU maintains playable frame rates across all quality presets.

The progression of FPS values across settings and resolutions shows a consistent pattern: each step from Low to Ultra reduces frame rate by roughly 15-20%, and each resolution step from 1080p to 1440p to 4K reduces frame rate by approximately 35-45%. This linear scaling indicates a well-balanced system where neither component is dramatically over- or under-powered for the other.
