Doom

The AMD Ryzen 7 7700 and Radeon RX 6600 XT combination delivers a highly capable 1080p experience in Doom, but the data reveals a clear shift in bottleneck behavior as resolution climbs. At 1920x1080, the system is firmly CPU-bound at lower presets, with the Low preset hitting 193.7 FPS and Medium at 165.9 FPS. The High preset still manages a robust 141 FPS, while Ultra drops to 116.1 FPS. These figures indicate that the Ryzen 7 7700’s strong single-thread performance is keeping the pipeline fed, as the GPU has headroom to spare at this resolution.

Moving to 2560x1440, the scaling pattern changes. The Low preset averages 126.1 FPS, which is a 35% reduction from the 1080p Low result, showing that the GPU is now taking on more of the load. Medium drops to 110.2 FPS, High to 90.6 FPS, and Ultra to 76.5 FPS. The gap between Low and Ultra at 1440p is 49.6 FPS, which is narrower than the 77.6 FPS spread seen at 1080p. This tighter range suggests that the RX 6600 XT is becoming the primary constraint, though the CPU’s 8-core, 16-thread configuration still provides enough throughput to avoid severe stutters.

At 3840x2160, the GPU is unquestionably the limiting factor. The Low preset produces 66.9 FPS, Medium 61.7 FPS, High 46.3 FPS, and Ultra 39.6 FPS. The delta between Low and Ultra here is just 27.3 FPS, indicating that even at the lowest settings, the RX 6600 XT’s 256.0 GB/s memory bandwidth and 10.60 TFLOPS of FP32 performance are saturated. The 4K numbers are playable for a cinematic experience, but they fall short of the high-refresh-rate territory the CPU can support at lower resolutions. The data shows that this combo is best suited for 1080p and 1440p gaming, with 4K reserved for less demanding titles or those willing to accept sub-60 FPS.

CPU Role

The AMD Ryzen 7 7700 is a 7000-series desktop processor built on the Zen 4 architecture with a 5 nm process. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.30 GHz. Its 32 MB of shared L3 cache and 83.2 GB/s of dual-channel DDR5 memory bandwidth provide a solid foundation for gaming workloads. In synthetic benchmarks, the CPU scores 29302 in Cinebench R23 multi-core and 4136 in single-core, placing it in the 91st percentile among all CPUs. Its nearest rival, the AMD Ryzen 9 7940H, scores 40431 on average, a mere 0.1% difference, while the Intel Core i9-13905H is 0.6% ahead. This level of performance ensures that Doom’s game logic, physics, and AI threads are handled effortlessly.

In Doom specifically, the CPU’s role is most evident at 1080p, where frame rates exceed 140 FPS on High and approach 194 FPS on Low. The 16 threads allow the game to distribute its workload across multiple cores, preventing any single-thread bottleneck from capping performance. However, the benchmark results show that the CPU is not the limiting factor at higher resolutions. At 1440p, the frame rate drops by 35% from 1080p on Low, and at 4K, it drops by another 47% from 1440p. This scaling is characteristic of a GPU-bound scenario, where the CPU has ample headroom to feed the graphics card. The Ryzen 7 7700’s 5.30 GHz boost clock is particularly beneficial for maintaining high minimum frame rates, even if the average FPS is dictated by the GPU’s fill rate.

Settings Recommendations

The measured FPS data provides a clear hierarchy for optimizing the experience across resolutions. At 1920x1080, the High preset offers the best balance, delivering 141 FPS while maintaining visual fidelity. The Ultra preset still achieves 116.1 FPS, which is above the 100 FPS threshold for smooth gameplay, but the 24.9 FPS gain from dropping to High is more valuable than the marginal visual upgrade. For competitive play, the Low preset at 193.7 FPS is the obvious choice, but it sacrifices most of the game’s graphical effects.

At 2560x1440, the High preset at 90.6 FPS is the sweet spot. It provides a 14.1 FPS improvement over Ultra’s 76.5 FPS while retaining most of the visual enhancements. The Medium preset at 110.2 FPS is also viable for those who prefer higher refresh rates, but the drop from High to Medium is not as pronounced as the jump from Ultra to High. At 3840x2160, the data suggests that the Low preset at 66.9 FPS is the only setting that consistently stays above 60 FPS. The Medium preset at 61.7 FPS is borderline, but the High preset at 46.3 FPS and Ultra at 39.6 FPS are too choppy for a fast-paced FPS. For 4K, the recommendation is to use Low or Medium and rely on the game’s temporal upscaling techniques if available, though the data does not include those settings.

How This Combo Ranks

The AMD Ryzen 7 7700 and Radeon RX 6600 XT combination ranks 1183 out of 1681 tested combos in Doom. This places it in the 30th percentile of all combinations, which is a middle-of-the-pack result. The ranking reflects the GPU’s position in the broader market; the RX 6600 XT sits in the 71st percentile among all GPUs, but its nearest rivals include the NVIDIA GeForce GTX 980 Ti and AMD Radeon R9 M395X, which score nearly identically on average. The RTX 3070 is 0.9% ahead, while the AMD FirePro S7150 is 1.5% behind. This peer group suggests that the combo’s performance is consistent with mid-range hardware from previous generations.

The low combo rank is not a condemnation of the CPU, as the Ryzen 7 7700 is in the 91st percentile among all CPUs. Instead, it highlights that the RX 6600 XT is the weaker link in this pairing. In Doom, where frame rates are heavily influenced by GPU fill rate and memory bandwidth, the 8 GB of GDDR6 VRAM and 128-bit bus width limit the card’s ability to push high framerates at Ultra settings. The combo’s rank would likely be higher in CPU-bound titles, but in Doom’s optimized engine, the GPU’s ceiling is the primary constraint. For users with this pairing, the data suggests that upgrading the GPU would yield a larger performance boost than upgrading the CPU.

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with a 7 nm process, featuring 2048 shading units, 128 TMUs, and 64 ROPs. It has a base clock of 1968 MHz, a game clock of 2359 MHz, and a boost clock of 2589 MHz. Its 8 GB of GDDR6 memory operates on a 128-bit bus with 256.0 GB/s of bandwidth. The card’s transistor count of 11,060 million and die size of 237 mm² are modest by modern standards, but its 10.60 TFLOPS of FP32 performance is sufficient for 1080p and 1440p gaming. In synthetic benchmarks, it scores 16461 in PassMark G3D and 89263 in Geekbench Vulkan, placing it in the 71st percentile among all GPUs.

In Doom, the GPU’s role is defined by its scaling behavior. At 1080p, the card is able to push 193.7 FPS on Low, but this drops to 116.1 FPS on Ultra, a 40% reduction that shows the impact of increased shading and texture work. At 1440p, the same settings range from 126.1 FPS on Low to 76.5 FPS on Ultra, and at 4K, it falls to 66.9 FPS on Low and 39.6 FPS on Ultra. This trend reveals that the RX 6600 XT has enough raw power for 1080p High and 1440p Medium, but it struggles to maintain 60 FPS at 4K Ultra. The 32 RT cores are present, but Doom does not heavily utilize ray tracing, so their impact is minimal in this title. The card’s 256.0 GB/s memory bandwidth is sufficient for 1080p, but at 4K, the 8 GB VRAM capacity becomes a limiting factor, as the game’s high-resolution textures exceed the available memory, causing the frame rate to plummet on Ultra.
