Doom

The AMD Ryzen 9 9900X paired with the NVIDIA GeForce RTX 3080 was measured in Doom, a 2016 FPS title. The dataset includes average FPS across 1080p, 1440p, and 4K resolutions, each with Low, Medium, High, and Ultra presets. This combination ranks 524th out of 1,681 tested combos, with the CPU in the 94th percentile and the GPU in the 80th percentile of their respective benchmark pools.

Settings Recommendations

The measured rows show a clear hierarchy. At 1080p, the Low preset reaches 299.9 FPS, while Medium, High, and Ultra deliver 264.2, 223.8, and 179.9 FPS respectively. At 1440p, the same presets yield 193.1, 171.8, 142.7, and 117.3 FPS. At 4K, the numbers drop to 103, 90.2, 77.5, and 65.4 FPS. The High preset offers the best balance across all resolutions. It provides a substantial FPS advantage over Ultra—at 4K, High is 77.5 FPS versus 65.4 for Ultra. At 1440p, High is 142.7 FPS versus 117.3 for Ultra. At 1080p, High is 223.8 FPS versus 179.9 for Ultra. The Ultra preset appears to impose a heavy cost for marginal visual gains. For a fast-paced FPS, the High preset is the recommended choice, as it keeps frame rates well above 60 FPS even at 4K, and above 140 FPS at 1440p. The Low preset is only useful for extreme refresh rates, hitting 299.9 FPS at 1080p, but the visual compromise is significant. Medium is a viable fallback, but High is the sweet spot for this hardware in Doom. The performance penalty scales consistently across the preset ladder, making the choice between Medium and High a straightforward trade-off of visual fidelity for frame rate.

GPU Role

The RTX 3080 is built on the Ampere architecture with a GA102 chip, fabricated on an 8 nm process by Samsung. It contains 28,300 million transistors on a 628 mm² die. The GPU operates at a base clock of 1440 MHz and a boost clock of 1710 MHz. Its memory subsystem consists of 10 GB of GDDR6X on a 320-bit bus, providing 760.3 GB/s of bandwidth. The GPU has 8,704 shading units, 272 TMUs, and 96 ROPs, along with 68 RT cores and 272 tensor cores. Its pixel rate is 164.2 GPixel/s, and its texture rate is 465.1 GTexel/s. The FP32 performance is 29.77 TFLOPS. In Doom, the GPU's role is evident in the resolution scaling. The 10 GB VRAM is sufficient for the game's textures at all tested presets, as no data suggests a memory bottleneck. The GPU's average benchmark score is 35,787, placing it in the 80th percentile. Its nearest rivals include the AMD Radeon Pro Duo (35,860, -0.2%), the AMD Radeon 880M (35,646, 0.4%), the AMD Radeon RX 7900 GRE (36,101, -0.9%), and the NVIDIA GeForce RTX 5070 Ti Mobile (35,435, 1%). The RTX 3080's score is within 1% of these rivals, indicating a tightly clustered performance tier. The boost clock of 1710 MHz is the key driver for the high FPS observed at 1080p, where the GPU is not the primary limiter. However, at 4K, the GPU's compute and memory bandwidth become the deciding factors, as the FPS drops to 77.5 on High. The 8 nm process node and 628 mm² die size contribute to the GPU's 320 W TDP, which is a significant power draw but is supported by the suggested 700 W PSU. The launch MSRP for this GPU is 699 USD.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It is manufactured on a 4 nm process by TSMC, with 16,630 million transistors across a 2x 70.6 mm² die. The base clock is 4.40 GHz, and the boost clock is 5.60 GHz. The CPU has an 80 KB L1 cache per core, a 1 MB L2 cache per core, and a 64 MB shared L3 cache. It supports DDR5 memory on a dual-channel bus, with a bandwidth of 89.6 GB/s. The CPU's TDP is 120 W, and it uses the AMD Socket AM5. In Doom, the CPU's strong single-thread performance is critical. Its Cinebench R23 single-core score is 6,555, and its Geekbench single-core score is 3,341. The multi-threaded scores are equally impressive, with Cinebench R23 multi-core at 46,438 and Geekbench multi-core at 19,827. The CPU's average benchmark score is 54,450, placing it in the 94th percentile. Its nearest rivals are the AMD Ryzen 9 9900X3D (54,681, -0.4%), the Intel Core i7-14700F (54,097, 0.7%), the Intel Core Ultra 5 245K (55,304, -1.5%), and the Intel Core Ultra 5 245KF (55,421, -1.8%). The 9900X is effectively tied with these processors, with deltas under 2%. At 1080p Low, the CPU allows the GPU to reach 299.9 FPS, indicating that the CPU is not a bottleneck at lower resolutions. The 12 cores and 24 threads provide ample headroom for the game's engine, which is not heavily threaded but benefits from the high boost clock. The 4 nm process node and 2x 70.6 mm² die size allow for a 120 W TDP, which is modest for a 12-core part. The 89.6 GB/s memory bandwidth is ample for the game's data requirements. The launch MSRP for this CPU is $499.

How This Combo Ranks

The combination of the Ryzen 9 9900X and RTX 3080 ranks 524th out of 1,681 tested combos in Doom. This places the pairing in the upper portion of the tested field, meaning a majority of the 1,681 tested combos are ranked below it. The CPU's 94th percentile ranking and the GPU's 80th percentile ranking suggest a slight imbalance, with the CPU being relatively stronger than the GPU. However, the measured FPS data shows that this imbalance does not hinder performance in Doom. At 1080p High, the combo delivers 223.8 FPS. At 1440p High, it delivers 142.7 FPS. At 4K High, it delivers 77.5 FPS. The combo's rank of 524 out of 1,681 reflects the fact that many other combos include higher-end GPUs, but the RTX 3080's performance is still strong. The data is measured, not estimated, which adds confidence to the ranking. The CPU's high single-thread score (6,555 in Cinebench R23) ensures that the GPU is fed adequately, as evidenced by the 299.9 FPS at 1080p Low. The combo's overall standing is solid, and it would be a capable system for Doom at high refresh rates. The 524th rank out of 1,681 confirms that this pairing sits comfortably in the top tier of tested configurations, with the CPU's strong multi-threaded capabilities (46,438 in Cinebench R23) providing a stable foundation for the GPU's output.

Resolution Scaling

The measured FPS shows a clear scaling pattern across resolutions. At the High preset, the average FPS drops from 223.8 at 1080p to 142.7 at 1440p, and then to 77.5 at 4K. At the Low preset, the FPS drops from 299.9 at 1080p to 193.1 at 1440p, and then to 103 at 4K. The Medium preset drops from 264.2 to 171.8 to 90.2. The Ultra preset drops from 179.9 to 117.3 to 65.4. The scaling indicates that the GPU is the limiting component at higher resolutions. The FPS drops are substantial as the pixel count increases, which is characteristic of a GPU-bound scenario. The CPU's performance is sufficient to maintain high FPS at 1080p, as shown by the 299.9 FPS at Low, but the GPU's compute and memory bandwidth become the bottleneck as resolution increases. The 10 GB VRAM and 760.3 GB/s bandwidth are adequate for Doom, but the raw shading power (29.77 TFLOPS) is what drives the 4K results. The data shows that the RTX 3080 is the primary determinant of FPS in this game, while the Ryzen 9 9900X provides a stable platform without introducing a CPU-side bottleneck. The drop from 1080p to 1440p is steep, and the further drop to 4K is equally pronounced, confirming that the GPU's 8,704 shading units are the decisive factor in this title's performance envelope.
