Doom

The AMD Ryzen 5 7600X and AMD Radeon RX 6750 XT combination delivers a strong performance profile in Doom, with frame rates that scale predictably across resolutions and settings. The data indicates a system that is well-balanced at 1080p and 1440p, with 4K remaining playable at most quality presets. This analysis breaks down the measured results, examining how the components interact and what users can expect from this pairing.

Resolution Scaling

The measured FPS data shows a clear and consistent scaling pattern as resolution increases from 1920x1080 to 3840x2160. At 1080p with High settings, the combo achieves 178 FPS, which drops to 115 FPS at 1440p and further to 62 FPS at 4K. This represents a 35.4% performance decrease when moving from 1080p to 1440p, and a 46.1% decrease from 1440p to 4K. The pattern indicates that the GPU becomes the primary limiting factor at higher resolutions, as the pixel throughput demand increases substantially.

The scaling behavior across settings reveals important insights. At Low settings, the 1080p result is 242 FPS, dropping to 156 FPS at 1440p and 85 FPS at 4K. The percentage drops are 35.5% and 45.5% respectively, which is nearly identical to the High settings scaling. This consistency suggests that the resolution scaling is primarily driven by the GPU's rasterization throughput rather than CPU-bound scenarios, even at lower quality presets where the CPU could potentially become a bottleneck.

At Ultra settings, the scaling is more pronounced. The 1080p result is 145 FPS, dropping to 94 FPS at 1440p (35.2% decrease) and 51 FPS at 4K (45.7% decrease). The 4K Ultra result at 51 FPS is the only measured point that falls below the 60 FPS threshold, indicating that this combination requires a reduction in settings to maintain smooth gameplay at 4K. The similarity in scaling percentages across all settings suggests that the game's rendering workload scales uniformly with resolution, regardless of the quality preset.

The frame time data for Medium settings provides additional context. At 1080p Medium, the average FPS is 210 with a minimum of 179 and maximum of 242. The spread of 63 FPS between minimum and maximum indicates some variability, but the minimum remains well above playable thresholds. At 1440p Medium, the average is 136 FPS with a range of 116 to 157, showing a tighter spread of 41 FPS. At 4K Medium, the average drops to 74 FPS with a range of 63 to 85, where the minimum still stays above 60 FPS.

Settings Recommendations

The measured data suggests that the High preset provides the best balance of visual quality and performance across all three resolutions. At 1080p High, the combo achieves 178 FPS, which is 22.7% higher than the 145 FPS at Ultra. This headroom allows for smooth gameplay even in demanding scenes, and the visual difference between High and Ultra is often minimal in fast-paced FPS titles. At 1440p High, the 115 FPS result remains well above the 60 FPS threshold, providing a comfortable margin for competitive play.

For 4K gaming, the Medium preset is the recommended starting point. The 74 FPS average at 4K Medium is 45.1% higher than the 51 FPS at Ultra, and the minimum of 63 FPS ensures consistent frame delivery above the 60 FPS baseline. The High preset at 4K produces 62 FPS average, which is technically playable but leaves less headroom for frame time spikes. Users prioritizing frame rate stability should select Medium, while those wanting maximum visual fidelity can consider High with the understanding that performance will be closer to the threshold.

The Low preset offers the highest frame rates but comes with significant visual compromises. At 1080p Low, the 242 FPS result is 36% higher than High settings, which could benefit users with high refresh rate monitors. However, the diminishing returns from Medium to Low are less substantial, with 1080p Medium at 210 FPS only 15.2% lower than Low. The data indicates that Medium provides the best performance-per-visual-quality trade-off for users seeking maximum frame rates without sacrificing too much detail.

Ultra settings are only recommended for 1080p gaming, where the 145 FPS result remains highly playable. At 1440p, Ultra produces 94 FPS, which is still smooth but represents a 18.3% reduction from High. The 4K Ultra result of 51 FPS falls below the 60 FPS threshold, making it unsuitable for most gaming scenarios. Users should reserve Ultra for 1080p or short sessions at 1440p when visual fidelity takes priority over frame rate consistency.

The 2560 shading units, 160 texture mapping units, and 64 render output units provide the raw compute throughput needed for the game's rendering tasks.

The GPU's clock speeds are a key factor in its performance. The base clock is 2150 MHz, with a game clock of 2495 MHz and a boost clock of 2600 MHz. The boost behavior allows the GPU to increase its clock speed under load, which helps maintain frame rates in demanding scenes. The memory clock runs at 2250 MHz, translating to 18 Gbps effective, which works in conjunction with the 192-bit bus to deliver the 432.0 GB/s bandwidth.

The GPU's compute capabilities are substantial, with FP32 performance rated at 13.31 TFLOPS. This raw compute power is directly relevant to Doom's rendering workload, which relies on traditional rasterization techniques. The pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s indicate the GPU's ability to fill the screen with pixels and apply textures efficiently. These specifications explain why the GPU can maintain high frame rates at 1080p and 1440p, while the 4K results show the expected decrease as pixel throughput demands increase.

The GPU's position in the broader market is reflected in its percentile ranking of 71 among all GPUs.
