Doom

The AMD Ryzen 9 9900X and AMD Radeon RX 7700 XT combination delivers a highly capable Doom experience, with the data showing a clear shift in system bottleneck from 1080p to 4K. The 12-core, 24-thread Zen 5 processor, boosting up to 5.60 GHz, provides ample headroom for this title, while the Radeon RX 7700 XT’s 12 GB of GDDR6 memory becomes the primary constraint at higher resolutions.

CPU Role — cores, clocks, and how they relate to this game's results

The Ryzen 9 9900X’s specifications suggest it is not the limiting factor in this benchmark set. With 12 cores and 24 threads based on the Zen 5 architecture, the processor offers substantial parallel processing power. Its base clock of 4.40 GHz and boost clock of 5.60 GHz provide high single-thread performance, which is often critical for game logic and frame pacing in FPS titles like Doom.

Benchmark data supports this assessment. In the 3DMark 16-thread test, the CPU scores 12552, while its single-thread score is 1286. This spread indicates strong scaling across cores, but more importantly, the high single-thread score suggests the CPU can feed the GPU efficiently. The processor’s 64 MB of shared L3 cache and 1 MB L2 cache per core further reduce latency for frequently accessed game data. Its percentile ranking of 94 against all CPUs places it in the top tier of processors, meaning it outperforms the vast majority of installed hardware.

Looking at the nearest rivals, the Ryzen 9 9900X’s average benchmark score of 54450 is nearly identical to the AMD Ryzen 9 9900X3D, which scores 54681, a delta of only -0.4%. It is also within 1.8% of the Intel Core Ultra 5 245KF, which scores 55421. These negligible differences confirm that in terms of raw processing power, the 9900X is not a performance outlier that would skew game results; rather, it provides a stable, high-performance foundation. In the context of Doom, this CPU power translates to consistent frame delivery, with the measured FPS at 1080p reaching up to 262.3 FPS on Low settings, a figure that would be impossible if the CPU were a bottleneck.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combined ranking of this CPU-GPU pairing is solidly mid-pack. The data places this combo at rank 735 out of 1681 tested combinations. This position, slightly better than the 56th percentile, indicates that while this system is very capable, there are many other configurations that achieve higher average frame rates in Doom.

This ranking is a direct result of the GPU’s performance ceiling. While the CPU is in the 94th percentile, the GPU is only in the 73rd percentile. The combination’s rank of 735 reflects a system where the GPU is the more modest component. The RX 7700 XT’s average benchmark score of 30097 is nearly identical to its closest rival, the NVIDIA GeForce RTX 5060, which scores 30109 with a delta of 0%. This means the GPU is performing exactly as expected for its class. The combo rank, therefore, is not an indication of a mismatch or a poorly performing pairing, but rather a realistic representation of what a high-end CPU and a mid-to-high-end GPU can achieve together. The system is not a top-tier 4K powerhouse, but it is far from a low-end setup, and its rank reflects a position of strength for mainstream high-refresh-rate gaming.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS data reveals a classic GPU-bound scenario at higher resolutions. At 1920x1080 with Ultra settings, the combo produces 157.2 FPS. Moving to 2560x1440 on Ultra, the frame rate drops to 100.2 FPS, a significant reduction of 36%. At 4K (3840x2160) on Ultra, the average further falls to 55.5 FPS, a 45% drop from 1440p and a 65% drop from 1080p.

This scaling pattern is the signature of a GPU bottleneck. The CPU is powerful enough to maintain high frame rates at 1080p, where the GPU is less taxed. As resolution increases, the GPU must render more pixels, and its workload grows exponentially. The RX 7700 XT’s 12 GB of VRAM and 432.0 GB/s of memory bandwidth become the limiting factors. The data shows that at 4K Low settings, the average FPS is 93.9, which is dramatically higher than the 55.5 FPS at 4K Ultra. This 41% increase in performance when lowering settings from Ultra to Low at the same resolution confirms that the GPU’s compute and memory throughput, not the CPU, are the determining factors. If the CPU were the bottleneck, lowering graphics settings would yield much smaller FPS gains.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 7700 XT is the performance anchor for this system in Doom. Its specifications, including 12 GB of GDDR6 memory on a 192-bit bus, provide a bandwidth of 432.0 GB/s. The GPU’s boost clock is rated at 2544 MHz, with a game clock of 2171 MHz. These figures are substantial, but they are the ceiling for this configuration.

The GPU’s role becomes clearer when analyzing the frame rates. At 1080p, the GPU is able to push frame rates well beyond 200 FPS on lower settings, reaching 262.3 FPS on Low. However, its performance is heavily influenced by settings and resolution. The 12 GB VRAM capacity is sufficient for 1080p and 1440p, but at 4K with Ultra settings, the demands on memory bandwidth and compute units increase, leading to the observed 55.5 FPS average. The GPU’s 96 ROPs and 216 TMUs are tasked with pixel and texture processing, and at 4K Ultra, they are saturated. This is why the 4K High preset (68.3 FPS) provides a playable experience, but the Ultra preset pushes the GPU past its comfortable limit. The GPU’s percentile rank of 73 against all GPUs confirms it is a solid performer, but not a top-tier enthusiast part, and the benchmark results directly reflect that positioning.

Settings Recommendations — which preset gives the best experience per the measured rows

For a 60 FPS target at 4K, the High preset is the only viable option, delivering 68.3 FPS. At 1440p, the data shows that Ultra settings provide an excellent experience with 100.2 FPS, which is well above the 60 FPS threshold and provides a smooth, high-fidelity experience. For players with high-refresh-rate monitors at 1440p, the Medium preset offers a substantial boost to 148.5 FPS, which is ideal for competitive play. At 1080p, the Ultra preset achieves 157.2 FPS, which is sufficient for most high-refresh-rate displays. The Low preset at 1080p, with 262.3 FPS, is only necessary for extreme competitive scenarios or 240Hz+ monitors. The optimal experience depends on the display. For a balanced 1440p setup, Ultra is the best choice, as it provides a high-quality image with frame rates that far exceed the standard 60 FPS target. The Medium preset is a strong alternative for those prioritizing maximum smoothness over visual fidelity.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured frame rates are as follows:

1920x1080:

• Low: 262.3 FPS
• Medium: 230.9 FPS
• High: 194.5 FPS
• Ultra: 157.2 FPS

2560x1440:

• Low: 171.6 FPS
• Medium: 148.5 FPS
• High: 126.0 FPS

• Medium: 77.9 FPS
• High: 68.3 FPS
• Ultra: 55.5 FPS

These figures illustrate a consistent performance hierarchy across all resolutions, with the Low setting providing the highest frame rates and Ultra the lowest. The gap between Low and Ultra widens as resolution increases, highlighting the growing pressure on the GPU. At 1080p, the difference between Low and Ultra is 105.1 FPS. At 1440p, this gap narrows slightly to 71.4 FPS. At 4K, the difference is 38.4 FPS. This trend confirms that the GPU’s rendering capabilities are the primary factor limiting performance, and the CPU is providing consistent, unchanging support across all tested scenarios.
