Doom

Resolution Scaling

The measured frame rates for Doom with the AMD Ryzen 7 7700X and AMD Radeon RX 6600 show a clear pattern of GPU-bound scaling as resolution increases. At 1080p with Low settings, the combo delivers 176.4 FPS, which drops to 115.4 FPS at 1440p and further to 61.6 FPS at 4K. This represents a 34.6% reduction from 1080p to 1440p and a 65.1% reduction from 1080p to 4K. The scaling curve is steep, indicating that the Radeon RX 6600 is the limiting component at higher resolutions.

Moving through Medium settings, the pattern holds: 152.6 FPS at 1080p, 98.4 FPS at 1440p, and 55.8 FPS at 4K. The drop from 1080p to 1440p is 35.5%, while the drop to 4K is 63.4%. High settings follow a similar trajectory with 126.6 FPS at 1080p, 85.9 FPS at 1440p, and 44 FPS at 4K — a 32.1% reduction to 1440p and a 65.2% reduction to 4K. Ultra settings show the most dramatic scaling: 107.4 FPS at 1080p falls to 71.1 FPS at 1440p (a 33.8% drop) and then to 36.9 FPS at 4K (a 65.6% drop).

The consistency of these percentage drops across all four settings presets is notable. Regardless of whether the game runs at Low or Ultra, the frame rate loss from 1080p to 4K hovers around 63-66%. This uniformity suggests that the rendering workload scales linearly with pixel count, and the RX 6600's memory bandwidth of 224.0 GB/s and 8 GB GDDR6 frame buffer become the decisive factors. The CPU's role diminishes at higher resolutions; the Ryzen 7 7700X, with its 8 cores and 16 threads, has ample headroom to feed the GPU at any resolution tested.

How This Combo Ranks

In the database of tested CPU-GPU combinations for Doom, this pairing sits at rank 1338 out of 1681 combos. That places it in the 20.4th percentile of all tested configurations, meaning roughly four out of five combos deliver higher average frame rates in this game. The ranking reflects the RX 6600's position as a mid-range GPU — its percentileVsAllGpus score of 69 indicates it outperforms most individual GPUs in synthetic benchmarks, but the combo rank shows that pairing it with the high-end Ryzen 7 7700X does not boost the overall standing dramatically.

The CPU itself is a top-tier part; its percentileVsAllCpus score of 89 and average benchmark score of 34,313 place it well above most processors. Its nearest rivals in synthetic benchmarks include the Intel Core i5-13500 (avg score 34,175, delta 0.4%), the Intel Core i7-12800HX (avg score 34,136, delta 0.5%), the Intel Core Ultra 7 165H (avg score 34,584, delta -0.8%), and the AMD EPYC 4244P (avg score 34,599, delta -0.8%). The Ryzen 7 7700X is effectively tied with these parts, all within a 1% band of each other.

The GPU's nearest rivals in synthetic testing are similarly close: the AMD Radeon 890M (delta 0%), the AMD Radeon RX 580 2048SP (delta -0.2%), the AMD Radeon RX 6700M (delta 0.2%), and the NVIDIA GeForce RTX 3060 Ti (delta 0.5%). The RX 6600's average benchmark score of 25,235 puts it in a tight cluster with these parts, none of which separate themselves by more than half a percent. This explains the modest combo rank — the GPU, not the CPU, determines where this pairing lands in Doom's performance hierarchy.

FAQ

Q: What is the best resolution for this combo in Doom?

A: The 1080p resolution provides the most headroom across all settings, with frame rates ranging from 107.4 FPS at Ultra to 176.4 FPS at Low. At 1440p, the combo remains playable with 71.1 FPS at Ultra and 115.4 FPS at Low, making it a viable option for high-refresh monitors.

Settings Recommendations

For a balanced experience, the Medium preset at 1440p delivers 98.4 FPS, which comfortably exceeds the 60 FPS target while maintaining visual quality over Low. At 1080p, Ultra settings at 107.4 FPS are entirely playable and offer the full visual experience without sacrificing smoothness. The High preset at 1080p (126.6 FPS) is a strong middle ground for players who want a margin of safety over the Ultra preset.

At 4K, the situation is more constrained. The Low preset at 61.6 FPS is the only setting that stays above 60 FPS, while Medium (55.8 FPS) and High (44 FPS) require a tolerance for sub-60 frame rates. Ultra at 4K drops to 36.9 FPS, which is not recommended for a game that relies on fast reaction times. Players with 4K displays should prioritize the Low preset or consider dropping to 1440p for better visual fidelity at higher frame rates.

The scaling pattern suggests that the RX 6600's 8 GB frame buffer and 224.0 GB/s bandwidth are the constraining factors at higher settings. The gap between Low and Ultra at any given resolution is consistent — roughly 39-40% — indicating that the GPU's shading units, texture units, and ROPs are being pushed harder as settings increase.

Measured FPS Breakdown

The complete measured dataset for this combo in Doom covers three resolutions and four settings presets. At 3840x2160, the average frame rates are: Low 61.6 FPS, Medium 55.8 FPS, High 44 FPS, and Ultra 36.9 FPS. The spread from Low to Ultra at 4K is 24.7 FPS, with each step up in settings costing roughly 5-9 FPS.

At 2560x1440, the average frame rates are: Low 115.4 FPS, Medium 98.4 FPS, High 85.9 FPS, and Ultra 71.1 FPS. The spread widens to 44.3 FPS, showing that the GPU has more headroom at this resolution. The step from Low to Medium costs 17 FPS, from Medium to High costs 12.5 FPS, and from High to Ultra costs 14.8 FPS.

At 1920x1080, the average frame rates are: Low 176.4 FPS, Medium 152.6 FPS, High 126.6 FPS, and Ultra 107.4 FPS. The spread is 69 FPS from Low to Ultra. The incremental costs are 23.8 FPS from Low to Medium, 26 FPS from Medium to High, and 19.2 FPS from High to Ultra. The 1080p results show the largest absolute differences between settings, confirming that the CPU is not the limiting factor here — the Ryzen 7 7700X can sustain frame rates well above 170 FPS at Low settings.

The data contains no minimum or maximum FPS values, so only average frame rates are available for analysis. All 12 measured data points are consistent with a GPU-bound workload that scales predictably with both resolution and settings.

CPU Role

The AMD Ryzen 7 7700X is a Zen 4 architecture processor built on a 5 nm process at TSMC, featuring 8 cores and 16 threads. Its base clock of 4.50 GHz boosts to 5.40 GHz, and it carries 32 MB of shared L3 cache alongside 1 MB of L2 cache per core. The processor supports DDR5 memory over a dual-channel bus with 83.2 GB/s bandwidth, and it connects via PCIe Gen 5 with 24 lanes. The launch MSRP was $399.

In Doom, the CPU's role is to feed the GPU with draw calls and game logic. The measured data shows that even the highest frame rates — 176.4 FPS at 1080p Low — do not appear to strain the CPU. The resolution scaling pattern is uniform, which would not be the case if the CPU were the bottleneck; a CPU-bound scenario would show similar frame rates at 1080p and 1440p. Instead, the frame rate drops proportionally with pixel count, indicating the GPU is saturated first.

The 7700X's synthetic benchmarks reinforce its capability. It scores 12,736 in Cinebench R20 multicore and 30,325 in Cinebench R23 multicore, with single-core scores of 1,798 and 4,281 respectively. Geekbench results are 15,538 multicore and 2,985 single-core. The Passmark multithread score of 35,686 and single-thread score of 4,190 place it in the upper tier of desktop processors. These numbers suggest the CPU can handle the demands of a 2016-era FPS like Doom without breaking a sweat.

The pairing with the RX 6600 means the CPU is likely idle much of the time in Doom, waiting on the GPU to complete rendering tasks. The 8-core, 16-thread configuration provides substantial headroom for background tasks or streaming while gaming. The 3DMark scores — 8,859 at 16 threads and 1,090 single-thread — confirm that the processor scales well with thread count, which is relevant for modern games that can leverage multiple cores, though Doom's engine appears to be primarily GPU-bound in this configuration.
