Doom

The AMD Ryzen 5 5600 and AMD Radeon RX 6750 XT combination delivers a thoroughly capable 1080p and 1440p experience in Doom, with the data showing a clear performance ceiling only at 4K Ultra settings. The benchmark results reveal a pairing where the GPU’s raw throughput is the dominant factor at higher resolutions, while the CPU’s six Zen 3 cores provide ample headroom for the game’s engine at lower settings.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, running on the AMD Socket AM4 platform. Its base clock of 3.50 GHz and boost clock of 4.40 GHz are backed by a 32 MB shared L3 cache. The chip’s benchmark scores reflect a strong balance for gaming: a Cinebench R23 multi-core score of 18309 and a single-core score of 2584. In the PassMark suite, it achieves a single-thread score of 3256 and a multi-thread score of 21541. These numbers place the CPU in the 79th percentile against all tested processors.

For Doom, a game originally released in 2016, the CPU’s role is primarily to feed the GPU with draw calls and physics data. The 3DMark results are telling: a single-thread score of 882 and a 2-thread score of 1737 suggest that the game’s engine, which is not heavily multi-threaded, will rely on the processor’s strong single-core performance. The 8-thread score of 4798 and the max-thread score of 5659 indicate that even if the game scales beyond two cores, the Ryzen 5 5600 has substantial reserve capacity. The data implies that at 1080p with Low settings, where the GPU load is minimal, the CPU is likely the limiting factor, yet the measured 238.5 FPS average shows it handles this scenario without bottlenecking the experience.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the Ryzen 5 5600 and the RX 6750 XT ranks 867 out of 1681 tested combos in Doom. This places it in the upper-middle tier of all system pairings, which is a reasonable result given that the game is nearly a decade old and many newer, more powerful components exist. The ranking suggests that while this combo is not at the top end, it significantly outperforms the median system.

Looking at the CPU’s nearest rivals, the Ryzen 5 5600’s average benchmark score of 21765 is nearly identical to the Intel Xeon D-1746TER, which scores 21635, a delta of just 0.6%. It also sits within a 0.9% margin of the Intel Core i7-11700F, which scores 21957. This indicates that the CPU’s performance is highly competitive with a range of server and desktop processors. For the GPU, the RX 6750 XT’s average score of 35327 is within a 1.3% delta of the NVIDIA GeForce RTX 3080, which scores 35787. The data suggests that this combo’s rank is driven more by the GPU’s relative standing than the CPU’s, as the GPU’s rival comparisons show it is slightly behind a high-end card from the same era.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear pattern of performance degradation as resolution increases, which is classic GPU-bound behavior. At 1080p with High settings, the average FPS is 175.8. Moving to 1440p drops this to 112.6, a reduction of 36%. At 4K, the average falls to 59.3, which is another 47% drop from 1440p. This scaling indicates that the RX 6750 XT’s rendering workload is the primary constraint at higher resolutions, as the CPU’s performance headroom becomes less relevant.

The Low settings data reinforces this interpretation. At 1080p Low, the combo achieves 238.5 FPS, which drops to 156 at 1440p and 83.9 at 4K. The percentage drops are similar to High settings, showing that even with reduced graphical load, the GPU remains the bottleneck. The Ultra settings tell a starker story: 147.6 FPS at 1080p, 95.4 at 1440p, and a sharp fall to 49.7 at 4K. The 4K Ultra result is below the 60 FPS threshold, which highlights that this combo is not suited for maximum fidelity at the highest resolution. The data suggests that the 12 GB of GDDR6 memory on the GPU, with a 192-bit bus and 432.0 GB/s bandwidth, is sufficient for Doom’s textures, but the raw compute power of the 13.31 TFLOPS FP32 performance is what limits 4K output.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a complete picture of the combo’s capabilities across three resolutions and four settings presets.

At 1920x1080, the performance is consistently high. The Low preset delivers an average of 238.5 FPS, the Medium preset achieves 209 FPS, and the High preset reaches 175.8 FPS. The Ultra preset, while still impressive, drops to 147.6 FPS. The gap between Low and Ultra is 90.9 FPS, which is a significant 38% reduction, indicating that the Ultra preset’s effects are costly.

At 2560x1440, the same progression is visible. Low averages 156 FPS, Medium drops to 134 FPS, and High falls to 112.6 FPS. The Ultra preset averages 95.4 FPS. The delta between Low and Ultra here is 60.6 FPS, a 39% reduction. This resolution is clearly the sweet spot for the combo, as even Ultra maintains a frame rate well above 60 FPS.

At 3840x2160, the GPU’s limits become evident. Low averages 83.9 FPS, which is still playable. Medium averages 76.2 FPS, and High averages 59.3 FPS, which is just below the 60 FPS target. The Ultra preset averages 49.7 FPS, which is noticeably less smooth. The drop from Low to Ultra at 4K is 34.2 FPS, a 41% reduction, showing that the GPU’s fill rate and shader processing are heavily taxed at this resolution.

Settings Recommendations — which preset gives the best experience per the measured rows

Given the measured data, the optimal settings depend on the target resolution. For 1080p, the High preset at 175.8 FPS offers a smooth experience, while the Ultra preset at 147.6 FPS still provides a high frame rate with maximum visual effects. The Low preset’s 238.5 FPS is only useful for competitive play where maximum refresh rate matters. The Medium preset at 209 FPS is a balanced middle ground.

For 1440p, the High preset at 112.6 FPS is the recommended choice, as it provides a clear visual upgrade over 1080p while maintaining a frame rate that is well above the 60 FPS standard. The Ultra preset at 95.4 FPS is also viable, but the 17.2 FPS difference between High and Ultra may not justify the increased graphical load. The Low preset at 156 FPS is excessive for most users.

For 4K, the data suggests that the High preset at 59.3 FPS is on the edge of playability, and the Ultra preset at 49.7 FPS is not recommended for a consistently smooth experience. The Medium preset at 76.2 FPS offers a better trade-off, while the Low preset at 83.9 FPS is the safest choice for maintaining high frame rates at this resolution. The analysis indicates that for the best overall experience, 1440p High is the sweet spot, as it combines solid visual quality with a 112.6 FPS average.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, manufactured on a 7 nm process at TSMC. It features a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. The GPU’s 2560 shading units, 160 texture mapping units, and 64 render output units deliver a pixel rate of 166.4 GPixel/s and a texture rate of 416.0 GTexel/s. The 13.31 TFLOPS of FP32 compute power is the key driver of the measured frame rates.

The GPU’s 12 GB of GDDR6 memory operates at an effective speed of 18 Gbps across a 192-bit bus, yielding a bandwidth of 432.0 GB/s. This memory configuration is more than sufficient for Doom, as the game’s textures do not stress the 12 GB capacity. The GPU’s benchmark scores support this: a PassMark G3D score of 20700 and a Geekbench Vulkan score of 109310. The GPU ranks in the 79th percentile of all GPUs, and its nearest rival, the NVIDIA GeForce RTX 3080, scores 35787 in the average benchmark, which is merely 1.3% higher.

The resolution scaling data confirms that the GPU is the primary bottleneck at higher resolutions. At 1080p Low, the combo achieves 238.5 FPS, but at 4K Ultra, it drops to 49.7 FPS. This 79% reduction in performance is directly attributable to the GPU’s rendering load. The GPU’s DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility ensure that Doom’s rendering paths are fully utilized. The data implies that while the CPU is capable, the RX 6750 XT’s compute resources are what determine the final frame rates, especially at 1440p and 4K where the GPU’s fill rate and shader processing are fully exercised.
