Doom

Resolution Scaling

The measured FPS deltas between 1080p and 4K reveal a system that is firmly GPU-limited in Doom, but with enough CPU headroom to keep frame pacing stable even at the most demanding settings. Moving from 1920x1080 to 2560x1440 at High settings drops the average frame rate from 145.8 FPS to 91 FPS, a reduction of roughly 38%. The subsequent jump to 3840x2160 at High yields 47.7 FPS, another 48% decline from the 1440p figure. This consistent, steep scaling curve is the classic signature of a graphics card that is being pushed to its pixel-throughput ceiling; the rendering workload grows geometrically with resolution, and the AMD Radeon RX 7600's 288.0 GB/s memory bandwidth and 2048 shading units become the binding constraint.

The scaling pattern holds across all quality presets. At Low settings, 1080p produces 194.8 FPS, 1440p produces 124.2 FPS, and 4K produces 67.6 FPS. The relative drops are 36% and 46% respectively, indicating that even when the graphical workload is minimized, the GPU still cannot maintain linear scaling as resolution rises. The CPU is not the limiting factor here; the AMD Ryzen 7 5700's 8 cores and 16 threads, running at a boost clock of 4.60 GHz, provide more than enough instruction throughput to feed the Radeon at every resolution tested. The data suggests that at 1080p Low, the system approaches a CPU-imposed ceiling around 195 FPS, but the 4K results are purely a function of the GPU's rasterization and memory subsystem limits.

Notably, the gap between Low and Ultra settings widens dramatically as resolution increases. At 1080p, the spread from Low (194.8 FPS) to Ultra (116.7 FPS) is 78.1 FPS. At 4K, the same spread shrinks to 26.0 FPS (67.6 FPS Low vs 41.6 FPS Ultra). This compression indicates that at 4K Ultra, the GPU is so saturated that the additional shading and texture work from Ultra settings cannot be fully expressed; the card is already at its memory bandwidth ceiling. In practical terms, users targeting 4K will see diminishing returns from lowering settings below Medium, while 1080p users have substantial headroom to crank quality without sacrificing frame rate.

CPU Role

The AMD Ryzen 7 5700 is a Zen 3 Cezanne part with 8 cores and 16 threads, base clock 3.70 GHz and boost 4.60 GHz. Its benchmark profile places it in the 84th percentile of all CPUs, with an average benchmark score of 27220. In Doom, a title built on the id Tech 6 engine that scales well across multiple threads, this CPU provides a robust foundation. The 16 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are sufficient to keep the Radeon RX 7600 fed with draw calls and geometry data.

Comparing the Ryzen 7 5700 to its nearest rivals, the data shows it is effectively tied with the Intel Core i9-9900K (deltaPct 0.7%), the Intel Core i7-12700H (deltaPct 0.8%), and the Intel Core i7-1370P (deltaPct 0.8%). The AMD Ryzen AI 5 340 trails by 1.2%. This means that in Doom, swapping between these four CPUs would produce nearly identical average FPS; the game's engine does not heavily penalize any of these architectures. The 3dmark scores reinforce this: 8-thread score of 5585 and max-thread score of 6617 show strong scaling, but the single-thread score of 901 indicates that Doom's primary thread is not a bottleneck at any resolution tested.

The CPU's 65 W TDP and 7 nm process node mean it runs cool and consistently, but that is a thermal characteristic, not a performance one. The benchmark results show that at 1080p Low, the system reaches 194.8 FPS, which is near the practical ceiling for this CPU-GPU pairing. If the CPU were weaker, we would expect to see a plateau at 1440p or 4K where FPS stops dropping with resolution; the data shows no such plateau, confirming the CPU is not the limiting component. The Cinebench R23 multicore score of 20655 and single-core score of 2916 further indicate a balanced processor that excels at both lightly-threaded and heavily-threaded workloads.

GPU Role

The AMD Radeon RX 7600 is the clear performance driver in this pairing. Its 8 GB of GDDR6 memory on a 128-bit bus delivers 288.0 GB/s of bandwidth, which is adequate for 1080p and 1440p but becomes strained at 4K. The GPU's base clock of 1720 MHz, game clock of 2250 MHz, and boost clock of 2655 MHz allow it to maintain high utilization across all four quality presets. The 64 ROPs and 128 TMUs are responsible for the pixel and texture fill rates, and the 21.75 TFLOPS FP32 throughput handles the shader work in Doom's Vulkan and OpenGL paths.

The GPU's benchmark profile shows a 63rd percentile ranking among all GPUs, with an average benchmark score of 20258. Its nearest rivals are telling: the AMD Radeon RX 7600 XT scores 0.6% higher, the AMD Radeon RX 460 scores 0.8% higher (an anomaly from benchmark variance), while the NVIDIA GeForce RTX 3070 Mobile scores 1.3% lower and the Intel Arc B570 scores 1.5% lower. This places the RX 7600 in a tight performance cluster, meaning that in Doom, the measured FPS differences between these GPUs would be negligible at most settings.

The GPU's 165 W TDP and dual-slot cooler are relevant for system integration, but the performance data is what matters. At 1080p Ultra, the RX 7600 produces 116.7 FPS, which is playable but not massively above the 144 Hz refresh rate that many monitors support. At 1440p Ultra, the 74.7 FPS figure is smooth for single-player but may not satisfy competitive players. At 4K Ultra, the 41.6 FPS result is below the 60 FPS threshold, confirming that this GPU is not designed for 4K Ultra in modern titles. The 8 GB VRAM capacity is sufficient for Doom at all settings, as the game's textures fit within that allocation, but the memory bus width limits the GPU's ability to scale to higher resolutions.

Measured FPS Breakdown

At 1920x1080, the RX 7600 delivers excellent performance across all presets. Low settings produce 194.8 FPS, Medium produces 171.9 FPS, High produces 145.8 FPS, and Ultra produces 116.7 FPS. The step from Low to Ultra costs 78.1 FPS, a 40% performance penalty, but even Ultra remains comfortably above 100 FPS. This resolution is where the pairing shines; the CPU and GPU are balanced, and users can run Ultra with high refresh rate monitors.

At 2560x1440, the performance drops are more pronounced. Low settings yield 124.2 FPS, Medium 110.4 FPS, High 91 FPS, and Ultra 74.7 FPS. The delta from Low to Ultra is 49.5 FPS, a 40% penalty that mirrors the 1080p scaling. The 74.7 FPS at Ultra is still playable, but users seeking 144 Hz will need to drop to Medium or Low. The 91 FPS at High is a good middle ground for 1440p, offering solid visual quality without sacrificing smoothness.

At 3840x2160, the GPU hits its limits. Low settings produce 67.6 FPS, Medium 60.5 FPS, High 47.7 FPS, and Ultra 41.6 FPS. The drop from Low to Ultra is 26.0 FPS, a 38% penalty. Only Low and Medium maintain 60 FPS or above, and even then, the margin is thin. High and Ultra fall below the 60 FPS threshold, making them unsuitable for smooth gameplay at 4K. The 47.7 FPS at High and 41.6 FPS at Ultra are playable with adaptive sync, but they represent a compromise between resolution and frame rate.

FAQ

Q: Can this system run Doom at 4K 60 FPS?

A: Only at Low settings (67.6 FPS) or Medium settings (60.5 FPS). At High (47.7 FPS) and Ultra (41.6 FPS), the frame rate drops below 60 FPS, so 4K 60 FPS is not achievable at higher quality presets.

Q: What is the best resolution for competitive play?

A: At 1080p Low, the system reaches 194.8 FPS, which is ideal for high refresh rate monitors. Even at 1080p Ultra, 116.7 FPS is well above the 60 FPS threshold, so 1080p is the recommended resolution for maximum frame rates.

Q: How does the CPU compare to its nearest rivals?

A: The AMD Ryzen 7 5700 is within 1.2% of all four nearest rivals in average benchmark score. It trails the Intel Core i9-9900K by 0.7%, the i7-12700H by 0.8%, and the i7-1370P by 0.8%, while leading the AMD Ryzen AI 5 340 by 1.2%. In Doom, these differences are negligible.

Q: Does the GPU have enough VRAM for Doom at 4K?

A: The 8 GB GDDR6 memory is sufficient for Doom at all settings tested. The game's texture requirements do not exceed 8 GB at 4K Ultra, as evidenced by the playable frame rates, but the 128-bit memory bus limits the effective bandwidth for high-resolution rendering.

Q: What frame rate can I expect at 1440p High?

A: The measured average is 91 FPS. This is a smooth experience for single-player and acceptable for most multiplayer scenarios, though competitive players may prefer 1440p Low (124.2 FPS) or 1440p Medium (110.4 FPS).

Q: Is the CPU or GPU the bottleneck at 1080p Low?

A: At 194.8 FPS, the system is approaching the practical ceiling for this pairing. The CPU's single-thread performance (3dmark single-thread score of 901) and the GPU's pixel rate (169.9 GPixel/s) are closely matched at this setting, so neither component is a clear sole bottleneck.

Settings Recommendations

For 1080p users, the Ultra preset at 116.7 FPS is the recommended choice. The 40% performance penalty from Low to Ultra is justified by the visual improvements, and 116.7 FPS remains above the 100 FPS threshold that most high refresh rate monitors can display. For 1440p, the High preset at 91 FPS strikes the best balance. Dropping to Medium (110.4 FPS) yields a 21% improvement but sacrifices noticeable shadow and texture quality; Ultra (74.7 FPS) is playable but leaves little headroom for frame drops in intense combat scenes. For 4K, the Medium preset at 60.5 FPS is the only viable option for maintaining 60 FPS, but Low (67.6 FPS) is recommended for users who prioritize frame rate stability. The data shows that the step from Medium to High at 4K costs 12.8 FPS (from 60.5 to 47.7), which is too steep a penalty for the marginal visual gain.

In all cases, the measured FPS values indicate that Doom's Vulkan renderer scales predictably with settings. The largest performance deltas occur between Low and Medium (approximately 23 FPS at 1080p, 14 FPS at 1440p, and 7 FPS at 4K), suggesting that the Medium preset is where the GPU's shading units become the limiting factor. Users with G-Sync or FreeSync displays can safely use the High preset at 1440p, as the 91 FPS average sits within the variable refresh rate window. For 4K users, no preset achieves 120 FPS, so the choice is between visual fidelity (High at 47.7 FPS) and playability (Medium at 60.5 FPS).

How This Combo Ranks

The AMD Ryzen 7 5700 + AMD Radeon RX 7600 combination ranks 1132nd out of 1681 tested combos in Doom. This places it in the 33rd percentile of all tested system configurations, meaning roughly two-thirds of the tested combos perform better in this game. This ranking is primarily dragged down by the GPU's 4K performance; at 1080p and 1440p, the combo delivers competitive frame rates, but the RX 7600's 8 GB memory and 128-bit bus limit its high-resolution capabilities.

The combo rank is consistent with the GPU's 63rd percentile ranking among all GPUs, but the CPU's 84th percentile ranking does not boost the overall position because Doom is GPU-bound at most settings. The 0.7% deltaPct to the Intel Core i9-9900K in CPU benchmarks does not translate to a meaningful FPS difference in this game, confirming that the CPU is not the limiting factor. The 1681 tested combos include many with higher-tier GPUs that achieve significantly better 4K performance, which is why the rank falls in the lower third despite strong 1080p results.

For users with 1080p or 1440p monitors, this combo's rank understates its practical performance. The measured FPS at 1440p High (91 FPS) and 1080p Ultra (116.7 FPS) are both well within the playable range, and the system handles the game's maximum settings at 1080p without issue. The low rank is a function of the test methodology that includes 4K results, where the RX 7600's limitations are most apparent. In the context of this benchmark database, the combo is a mid-tier performer that excels at lower resolutions but cannot compete with higher-end GPUs at 4K.
