Doom

The AMD Ryzen 7 5700X paired with the AMD Radeon RX 7600 delivers a highly playable Doom experience across most settings, but the data reveals a clear performance ceiling at higher resolutions. The benchmark results show that this combination is firmly GPU-limited at 4K, while at 1080p the CPU’s strong multi-threading keeps frame rates exceptionally high.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent across all quality presets, confirming that the RX 7600 is the primary bottleneck at higher resolutions. At High settings, the average frame rate falls from 144.5 FPS at 1920x1080 to 92.1 FPS at 2560x1440, a reduction of 52.4 FPS. Moving to 3840x2160, the average drops further to 52.3 FPS, which is a 36.3% decrease from the 1440p result and a 63.8% decrease from the 1080p figure. This pattern holds across every preset, indicating that the GPU’s rendering throughput is the limiting factor as pixel count increases.

The scaling behavior changes character between resolutions. From 1080p to 1440p, the frame rate drops by roughly 36-43% depending on settings, which is consistent with a GPU that has ample headroom at the lower resolution. However, the jump from 1440p to 4K produces an additional 43-45% reduction in frame rate, showing that the RX 7600’s 8 GB of GDDR6 memory and 128-bit bus are being saturated. At Low settings, the 4K average of 70.1 FPS is still respectable, but the gap between Low and Ultra at 4K is 26.8 FPS, which is the largest absolute spread across all resolutions. This suggests that the GPU’s compute units are heavily taxed by the higher-detail shaders at 4K, leaving less room for quality scaling.

At 1080p, the data shows a different dynamic. The difference between Low (191.9 FPS) and Ultra (114.6 FPS) is 77.3 FPS, indicating that the CPU can feed the GPU fast enough to make settings matter significantly. The fact that 1080p Ultra still exceeds 114 FPS means the Ryzen 7 5700X’s eight cores are not holding back performance at this resolution. The scaling from 1080p to 1440p at Ultra is 36.4%, which is less dramatic than the 4K drop, reinforcing that the GPU becomes the dominant constraint only when pixel count rises.

GPU Role

The RX 7600’s specifications directly explain the measured results. With 8 GB of GDDR6 memory on a 128-bit bus delivering 288.0 GB/s of bandwidth, the card has enough memory throughput for 1080p and 1440p gaming but struggles to maintain high frame rates at 4K. The boost clock of 2655 MHz and 2048 shading units provide solid raw compute, as evidenced by the 21.75 TFLOPS FP32 rating. However, the 64 ROPs and 128 TMUs are modest for a card targeting high-resolution play, which aligns with the observed 4K performance.

The GPU’s benchmark scores place it in the 63rd percentile among all GPUs, with an average benchmark score of 20258. Its nearest rival, the AMD Radeon RX 7600 XT, scores 20146, a delta of 0.6%, meaning the two cards are nearly identical in synthetic tests. The RX 7600 also trails the Intel Arc B570 by 1.5% and the NVIDIA GeForce RTX 3070 Mobile by 1.3%, showing that this is a mid-range card in a very tight performance cluster. In Doom specifically, the 4K High result of 52.3 FPS suggests the GPU is working near its limit, as the memory bandwidth and ROP count cannot sustain higher output.

The 165 W TDP and 450 W suggested PSU are consistent with the card’s positioning, but the data indicates that the RX 7600 is better suited to 1440p gaming. At 2560x1440, every preset except Ultra stays above 90 FPS, with High hitting 92.1 FPS and Medium reaching 110 FPS. The 4K results, while playable at Low and Medium, do not offer the headroom needed for consistent high-refresh-rate experiences.

How This Combo Ranks

In the database of tested combinations, this CPU-GPU pair ranks 1134 out of 1681 combos for Doom, placing it in the lower third of all configurations. This ranking reflects the fact that while the CPU is strong, the GPU holds the combo back from higher positions. The Ryzen 7 5700X alone sits in the 83rd percentile among all CPUs, with an average benchmark score of 26214, but the RX 7600’s 63rd percentile standing pulls the combined result down.

The combo rank of 1134 out of 1681 means that roughly 547 tested combinations deliver higher average frame rates in Doom. This is not surprising given that the RX 7600 is a mid-range GPU, and many higher-tier cards with more memory bandwidth and compute units will outperform it. However, within its own class, the combo is competitive. The CPU’s nearest rivals include the Intel Core i9-11900KF with a delta of 0.1% and the AMD Ryzen 5 5500GT with a delta of 0.2%, meaning the 5700X is essentially tied with these processors in synthetic benchmarks. The GPU’s nearest rivals are similarly close, with the RX 7600 XT just 0.6% ahead, so the combo’s ranking is more about the GPU class than the specific silicon.

Measured FPS Breakdown

At 1920x1080, the combo delivers excellent performance across all settings. Low settings produce an average of 191.9 FPS, Medium 169.1 FPS, High 144.5 FPS, and Ultra 114.6 FPS. These numbers show that the CPU is not a limiting factor at this resolution, as even Ultra surpasses the 100 FPS threshold. The scaling from Low to Ultra is 40.3% slower, which is a typical range for a GPU-bound scenario.

At 2560x1440, the averages are 127.5 FPS on Low, 110 FPS on Medium, 92.1 FPS on High, and 73 FPS on Ultra. The gap between Low and Ultra widens to 42.7%, indicating that the GPU is starting to feel the pressure of higher pixel counts. The 73 FPS Ultra result is still playable but below the 75 FPS threshold that many gamers prefer for smooth motion.

At 3840x2160, the results are 70.1 FPS on Low, 57.8 FPS on Medium, 52.3 FPS on High, and 43.3 FPS on Ultra. The Low setting is the only one that stays above 60 FPS, and even that is marginal. Ultra at 43.3 FPS is noticeably choppy for a fast-paced FPS like Doom. The spread from Low to Ultra is 26.8 FPS, which is the largest absolute difference across all resolutions, confirming that the GPU’s compute resources are the primary constraint at 4K.

CPU Role

The Ryzen 7 5700X provides ample processing power for this game, with 8 cores and 16 threads based on the Zen 3 architecture. Its boost clock of 4.60 GHz and 32 MB of shared L3 cache contribute to strong single-thread and multi-thread performance. In synthetic benchmarks, the CPU scores 22620 in Cinebench R23 multi-core and 3193 in single-core, placing it well above average. The 3DMark results show a 16-thread score of 6858, which indicates that the CPU can handle heavily threaded workloads without issue.

In Doom, the CPU’s role is to feed the GPU with draw calls and physics calculations. The 1080p Low result of 191.9 FPS suggests that the CPU is not bottlenecking, as this frame rate is near the practical limit for many engines. The 2-thread 3DMark score of 1821 and single-thread score of 921 show that the CPU has solid per-core performance, which is crucial for games that depend on a few fast threads. The CPU’s nearest rival, the AMD Ryzen 5 7600X, has an average score of 26272, a delta of -0.2%, meaning the 5700X is essentially equivalent in overall CPU performance.

At 4K, the CPU becomes even less relevant, as the GPU is clearly the limiting factor. The fact that frame rates drop uniformly across all settings at 4K, regardless of CPU load, confirms that the CPU is not a constraint in this configuration.

Settings Recommendations

For the best balance of visual quality and frame rate, the Medium preset at 2560x1440 is the optimal choice. The 110 FPS average is well above the 90 FPS threshold for smooth gameplay, and the visual upgrade from Low is noticeable. If a higher frame rate is preferred, dropping to Low at 1440p yields 127.5 FPS, but the visual fidelity loss is significant.

At 1080p, the High preset at 144.5 FPS is the recommended setting for most users, as it provides a strong visual experience without sacrificing performance. For competitive play, the Low preset at 191.9 FPS offers the highest responsiveness, but the data shows that even Ultra at 114.6 FPS is playable on high-refresh-rate monitors.

At 4K, the Low preset at 70.1 FPS is the only option that maintains a playable frame rate. The Medium preset at 57.8 FPS is borderline, and High at 52.3 FPS will feel noticeably less smooth. Ultra at 43.3 FPS should be avoided for fast-paced action. The data clearly indicates that this combo is not designed for 4K gaming, and users should stick to 1440p or 1080p for the best experience.
