Doom

The AMD Ryzen 7 5700 paired with the AMD Radeon RX 6600 XT delivers a remarkably consistent experience in Doom, with performance scaling that clearly identifies the GPU as the primary constraint as resolution increases. This combination lands at rank 2660 out of 3712 tested combos, placing it in a solidly mid-pack position for this title. The data shows a system that is exceptionally well-suited for high-refresh-rate 1080p gaming, capable of hitting near-maximum settings, while remaining perfectly playable at 1440p with only minor compromises. At 4K, the limits of the graphics card become apparent, but the frame rates remain respectable for a single-player FPS.

Resolution Scaling

The frame rate behavior across the three tested resolutions reveals a textbook GPU-bound scaling curve. At 1920x1080 with High settings, the system produces an average of 141 FPS. Moving to 2560x1440, that average drops to 91 FPS, which represents a 35% reduction in performance. Pushing further to 3840x2160, the average falls to 49 FPS, another 46% drop from the 1440p figure. This steep decline is the clearest indicator that the Radeon RX 6600 XT is the limiting component at higher resolutions; the CPU is providing enough headroom that it is not the bottleneck in this scenario.

The scaling pattern is consistent across all quality presets. At Low settings, the frame rate drops from 192 FPS at 1080p to 124 FPS at 1440p (a 35% reduction) and then to 67 FPS at 4K (a 46% reduction). The consistency of these percentage drops—roughly one-third from 1080p to 1440p and nearly half from 1440p to 4K—is a strong signal that the workload is scaling with pixel count, which is the definition of a GPU-limited workload. If the CPU were the bottleneck, we would expect to see a much smaller frame rate delta between 1080p and 1440p, as the CPU load would remain relatively constant while the GPU load increased.

The gap between Low and Ultra settings widens as resolution increases, which is another confirmation of GPU dependency. At 1080p, the difference between Low (192 FPS) and Ultra (115 FPS) is 77 FPS. At 1440p, the difference is 49 FPS (124 vs 75), and at 4K, the difference shrinks to 27 FPS (67 vs 40). This tightening gap at higher resolutions occurs because the GPU is already saturated with pixel work, leaving fewer resources available to process the additional visual effects that Ultra settings demand. The data suggests that for users targeting 4K, upgrading the graphics card would yield significantly greater returns than any CPU change.

CPU Role

The AMD Ryzen 7 5700 is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. Its benchmark scores indicate a strong multi-threaded performer for its class, with a Cinebench R23 multi-core score of 20655 and a single-core score of 2916. The CPU's 78th percentile ranking among all tested CPUs reflects its capable all-round performance, but in Doom, the evidence points to the CPU having ample headroom to feed the GPU effectively at lower resolutions.

Examining the 1080p results provides the clearest view of CPU performance. At Low settings, the system achieves 192 FPS, which is a very high frame rate that demands substantial CPU work for game logic and draw calls. The fact that the system can maintain this average suggests the Ryzen 7 5700 is not a limiting factor at this resolution. The processor's 3DMark scores, including a 16-thread score of 6628 and a single-thread score of 901, show a balanced profile that suits modern game engines which rely on a mix of single-thread latency and multi-thread scaling.

The 16 MB of L3 cache and dual-channel DDR4 memory support provide the necessary bandwidth for fluid frame pacing in a fast-paced FPS. While the CPU's performance is more than adequate for this title, the data does not suggest it is providing any extraordinary advantage either. The frame rate scaling between resolutions is governed almost entirely by the GPU's fill rate and compute throughput. The Ryzen 7 5700 is simply a solid, dependable foundation that allows the Radeon RX 6600 XT to perform to its full potential. For this specific game, the CPU's role is to stay out of the way, and the benchmark results indicate it does exactly that.

How This Combo Ranks

Within the extensive database of 3712 tested combinations, this pairing of the Ryzen 7 5700 and RX 6600 XT achieves the 2660th position. This places it in the 28th percentile of all combos, which is a lower ranking than the individual components might suggest given that the CPU sits in the 78th percentile and the GPU in the 70th percentile. This discrepancy indicates that while the components are individually capable, their combined performance in Doom is not exceptional when compared to other high-end pairings that likely feature more powerful graphics cards.

The ranking suggests that this combo is a competent mid-range solution rather than a top-tier performer. It is important to note that the combo rank is specific to Doom and reflects the game's particular engine characteristics and optimization. The RX 6600 XT's nearest rivals in the overall GPU benchmark averages include the NVIDIA GeForce GTX 1630 with a delta of 0.7%, the Intel Arc A350M with a delta of -0.8%, the NVIDIA GeForce GTX 780 Ti with a delta of 0.8%, and the NVIDIA GeForce RTX 2080 SUPER with a delta of 1.1%. These extremely small deltas, all within about one percentage point, suggest that the RX 6600 XT performs nearly identically to a wide range of other graphics cards in general compute benchmarks, but its specific game performance can vary.

For Doom, the measured FPS indicates that the combo's mid-pack ranking is not a reflection of poor playability. At 1080p and 1440p, the system delivers frame rates well above the threshold for smooth gameplay. The rank is more a measure of how many other combinations in the database achieve higher absolute frame rates, which is logical given that the database includes many systems with far more powerful and expensive GPUs. The practical takeaway from the rank is that this combo sits in the middle of the pack, offering a balanced experience that will not disappoint but also will not top any leaderboards.

Measured FPS Breakdown

At 1920x1080, the system shows excellent performance across all settings. Low settings produce an average of 192 FPS, which is an exceptionally high frame rate that would satisfy the most demanding competitive players. Medium settings reduce this to 167 FPS, with a measured minimum of 142 FPS and a maximum of 192 FPS, indicating a stable frame delivery. High settings yield 141 FPS, and Ultra settings still manage a very respectable 115 FPS. The spread from Low to Ultra at 1080p is significant, but even the lowest average at Ultra is more than sufficient for a smooth experience on a high-refresh-rate monitor.

Moving to 2560x1440, the frame rates remain highly playable. Low settings average 124 FPS, which is a substantial drop from the 1080p figure but still very smooth. Medium settings average 108 FPS with a minimum of 92 FPS and a maximum of 124 FPS. High settings produce 91 FPS, which is comfortably above the 60 FPS standard for a fast-paced game. Ultra settings drop to 75 FPS, which is still very playable and demonstrates that this combo can handle 1440p with most quality features enabled.

At 3840x2160, the GPU begins to show its limitations. Low settings average 67 FPS, which is playable but no longer high-refresh-rate territory. Medium settings average 59 FPS with a minimum of 50 FPS and a maximum of 67 FPS, putting it right at the edge of smooth gameplay. High settings drop to 49 FPS, and Ultra settings fall to 40 FPS. The 4K results clearly show that this combo is not designed for maximum quality at this resolution, but the Low and Medium settings still offer a playable experience for those who prioritize resolution over visual fidelity.

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with 2048 shading units, 128 texture mapping units, and 64 render output units. It operates at a base clock of 1968 MHz, a game clock of 2359 MHz, and a boost clock of 2589 MHz. The GPU has 8 GB of GDDR6 memory on a 128-bit bus, providing a memory bandwidth of 256.0 GB/s. These specifications make it a capable mid-range graphics card, and its 70th percentile ranking among all GPUs confirms its position.

In Doom, the GPU's performance is the defining factor in the system's overall results. The 1080p frame rates, ranging from 115 FPS at Ultra to 192 FPS at Low, demonstrate that the GPU has ample compute and memory bandwidth to handle the game's demands at this resolution. The 256.0 GB/s memory bandwidth is sufficient for the texture and geometry data at 1080p, and the 10.60 TFLOPS of FP32 compute power is more than enough to drive the rendering pipeline at high frame rates.

The GPU's role becomes more critical as resolution increases. At 1440p, the frame rates are still high, but the drop from 1080p indicates the GPU is working harder to fill more pixels. At 4K, the GPU is clearly the bottleneck, as evidenced by the significant frame rate reductions. The 8 GB of VRAM is a potential concern at 4K with high-resolution textures, but the measured results show that the game still runs, albeit at lower average frame rates. The GPU's nearest rivals in terms of average benchmark score, such as the NVIDIA GeForce GTX 1630 and the NVIDIA GeForce RTX 2080 SUPER, are within a 1.1% delta, which suggests that in general-purpose workloads, these cards perform similarly, but in Doom specifically, the RX 6600 XT's architecture appears to be well-optimized, as the measured frame rates are quite competitive for its class.

Settings Recommendations

For users with a 1920x1080 display, the Ultra preset is the clear choice. The measured average of 115 FPS is well above the threshold for smooth gameplay on a standard 60 Hz monitor and provides a great experience on a 120 Hz or 144 Hz display. The jump from High (141 FPS) to Ultra (115 FPS) is only a 26 FPS difference, but the visual quality improvements in texture filtering, shadow detail, and lighting effects are typically worth the performance cost. For competitive players who prioritize maximum frame rates, the Low preset at 192 FPS offers a significant advantage in responsiveness, but the Medium preset at 167 FPS provides a better balance of visual quality and speed.

At 2560x1440, the High preset is the recommended starting point. The 91 FPS average is smooth and provides a great balance between visual fidelity and performance. Users who want to maximize visual quality can select Ultra at 75 FPS, which is still very playable. The Medium preset at 108 FPS is an excellent option for those who prefer higher frame rates over the extra visual effects, and it offers a significant performance boost over High. The Low preset at 124 FPS is available for those who need the absolute highest frame rates, but the visual compromise is often too great for a visually rich game like Doom.

For 3840x2160 displays, the data suggests that the Low preset at 67 FPS is the only setting that provides a consistently smooth experience. The Medium preset at 59 FPS is borderline playable, with a minimum FPS of 50, which may be acceptable for slower-paced sections but could feel choppy during intense action. The High and Ultra presets at 49 FPS and 40 FPS, respectively, are not recommended for a game that demands quick reactions. Users with 4K displays should adjust their expectations and either lower the resolution to 1440p for a better experience or accept the visual compromises of the Low preset. The measured data indicates that this combo is best utilized at 1080p or 1440p, where it can deliver high frame rates with high-quality settings.
