Doom

The AMD Ryzen 7 5800X and AMD Radeon RX 6600 combination ranks 1323rd out of 1681 tested combos in Doom. That places this pairing in the lower 21% of all configurations tested, a surprisingly modest position given the hardware's individual capabilities. The ranking reflects a system that delivers playable frame rates across most settings but lacks the headroom to compete with top-tier combos, particularly at higher resolutions where the GPU becomes the decisive factor.

How This Combo Ranks

The combo's rank of 1323 out of 1681 tested combinations places it in the 79th percentile from the bottom — a clear signal that while this pairing can run Doom, it does so without distinction. The CPU sits in the 84th percentile among all CPUs, while the GPU lands in the 69th percentile among all GPUs, yet their combined performance in this title underperforms what those individual percentiles might suggest.

The data indicates this is a case where the GPU limits overall system potential. At 1080p Ultra, the combo produces 108.1 FPS, which is respectable, but the gap between the CPU's strong synthetic benchmarks and the actual in-game results points to the RX 6600 as the bottleneck. The Ryzen 7 5800X's 3DMark max threads score of 7578 and Cinebench R23 multi-core score of 23571 demonstrate substantial processing power, but Doom's frame rates at higher settings show the GPU cannot fully exploit that CPU capability.

CPU Role

The AMD Ryzen 7 5800X brings 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.80 GHz and boost clock of 4.70 GHz. These specifications provide ample processing headroom for Doom, a title that does not heavily stress multi-threaded workloads. The CPU's single-thread performance, reflected in its Cinebench R23 single-core score of 3327, ensures that game logic and physics calculations are handled efficiently.

In this combo, the CPU is not the limiting factor. The measured frame rates show that even at 1080p Low, where CPU load is proportionally higher, the system reaches 177.3 FPS, indicating the processor can feed frames well beyond what the GPU can render at higher settings. The Ryzen 7 5800X's nearest rivals include the AMD Ryzen 7 5800 with an average score of 27535 (0.3% higher) and the Intel Core i5-12600KF at 27827 (0.8% higher), showing this CPU performs competitively within its class. The 32 MB of L3 cache and dual-channel DDR4 memory support contribute to consistent frame delivery, but the game's results suggest that even a less powerful CPU would produce similar FPS in this pairing.

GPU Role

The AMD Radeon RX 6600 features 8 GB of GDDR6 memory on a 128-bit bus with 224.0 GB/s bandwidth. Its boost clock reaches 2491 MHz with a game clock of 2044 MHz, and it contains 1792 shading units, 112 TMUs, and 64 ROPs. The GPU's 69th percentile ranking among all GPUs places it in the mid-range tier, and the measured results confirm this positioning.

The GPU's role becomes increasingly dominant as resolution rises. At 1080p Ultra, the combo generates 108.1 FPS, but at 1440p Ultra that drops to 69.1 FPS, and at 4K Ultra it falls to 40 FPS. This scaling pattern reveals that the RX 6600's 8 GB VRAM and 224.0 GB/s bandwidth are sufficient for 1080p but struggle to maintain high frame rates at 4K. The GPU's nearest rival, the AMD Radeon RX 580 2048SP, scores 25287 in average benchmarks, just 0.2% higher, while the NVIDIA GeForce RTX 3060 Ti scores 25120, 0.5% lower — indicating the RX 6600 sits in a tightly contested performance band.

FAQ

Q: What is the best resolution for this combo to achieve 100+ FPS?

A: At 1080p, the combo achieves 130.7 FPS on High and 156.1 FPS on Medium, while at 1440p Medium it hits exactly 100 FPS. For 100+ FPS consistently, 1080p with High settings is the safest choice.

Q: How does the CPU compare to its closest rival?

A: The Ryzen 7 5800X has an average benchmark score of 27606, which is 0.3% higher than the AMD Ryzen 7 5800's 27535 and 0.4% higher than the AMD Ryzen 5 8500GE's 27708. It trails the Intel Core i5-12600KF by 0.8%.

Q: Does the GPU outperform its nearest competitor?

A: The RX 6600's average benchmark score of 25235 is essentially tied with the AMD Radeon 890M at 25246 (0% delta) and the AMD Radeon RX 6700M at 25180 (0.2% higher). It outperforms the RX 580 2048SP by 0.2% but trails the RTX 3060 Ti by 0.5%.

Q: Can this combo handle Ultra settings at 1440p?

A: Yes, it produces 69.1 FPS at 1440p Ultra. This is playable but below the 100 FPS threshold many FPS players prefer. Dropping to High settings improves it to 85.8 FPS.

Q: What FPS can be expected at 4K?

A: At 4K, the combo achieves 43.3 FPS on High, 55.4 FPS on Medium, and 40 FPS on Ultra. Only the Low setting reaches 64 FPS at 4K, so 4K gaming is possible but with compromises.

Q: How much performance is lost between Low and Ultra at 1080p?

A: The 1080p Low setting yields 177.3 FPS while Ultra produces 108.1 FPS, representing a 69.2 FPS drop or approximately 39% fewer frames when moving from Low to Ultra.

Resolution Scaling

The measured data shows a clear progression of frame rates as resolution increases. At 1080p Low, the combo delivers 177.3 FPS, which drops to 114.5 FPS at 1440p Low (a 62.8 FPS decrease) and further to 64 FPS at 4K Low (a 50.5 FPS decrease from 1440p). The scaling pattern indicates the GPU becomes progressively more stressed as pixel count rises.

At High settings, the transitions are 130.7 FPS at 1080p, 85.8 FPS at 1440p, and 43.3 FPS at 4K. The percentage drops from 1080p to 1440p are 34.4% for High and 35.4% for Low, showing a consistent pattern. From 1440p to 4K, the drops are 49.5% for High and 44.1% for Low. This analysis reveals that the limiting component is the GPU, as the CPU's strong multi-threaded performance (3DMark max threads score of 7578) cannot compensate for the GPU's bandwidth and memory constraints at higher resolutions. The 8 GB VRAM capacity becomes a factor at 4K Ultra, where the combo drops to 40 FPS.

Settings Recommendations

The optimal balance between visual quality and frame rate occurs at 1080p with High settings, delivering 130.7 FPS. This provides the smooth gameplay FPS players require while maintaining good visual fidelity. At 1440p, High settings at 85.8 FPS offer a reasonable experience, though competitive players may prefer Medium at 100 FPS.

For 4K, the data shows that only Low settings achieve 64 FPS, which is playable but visually compromised. Medium at 4K produces 55.4 FPS, which may be acceptable for slower-paced play but is not ideal for Doom's fast action. The Ultra preset at any resolution above 1080p results in frame rates below 70 FPS, making it the least recommended option. The measured rows indicate that Medium settings at 1440p provide the best compromise for users prioritizing frame rate over maximum detail, while High at 1080p is the overall sweet spot.

Measured FPS Breakdown

At 1920x1080, the combo achieves 177.3 FPS on Low, 156.1 FPS on Medium, 130.7 FPS on High, and 108.1 FPS on Ultra. These figures demonstrate that the RX 6600 can comfortably handle 1080p with high refresh rates across all settings.

At 2560x1440, the results are 114.5 FPS on Low, 100 FPS on Medium, 85.8 FPS on High, and 69.1 FPS on Ultra. The 1440p resolution shows a steeper drop-off at higher settings, with Ultra falling below the 70 FPS threshold.

At 3840x2160, the combo produces 64 FPS on Low, 55.4 FPS on Medium, 43.3 FPS on High, and 40 FPS on Ultra. The 4K results highlight the GPU's limitations, with only the Low preset achieving 60 FPS or higher. The progression across resolutions confirms that the RX 6600 is best suited for 1080p gaming, with 1440p being a viable secondary option at medium settings.
