Doom

Resolution Scaling

The measured frame rates across resolutions reveal a classic GPU-bound scaling pattern for Doom with the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 3070. At 1080p High settings, the combo delivers 187.9 FPS average. Moving to 1440p High drops that to 121.3 FPS, a 35.5% reduction, and 4K High falls to 70.1 FPS, which is 62.7% below the 1080p result. This steep decline as pixel count rises indicates the RTX 3070 is the primary limiting component at higher resolutions, while the 12-core CPU has ample headroom.

The scaling pattern holds across all settings presets. At Low settings, 1080p produces 259.1 FPS, 1440p produces 168.8 FPS, and 4K produces 91.3 FPS. The 4K Low result is 64.8% lower than 1080p Low, showing that even at the lowest graphical load, resolution dictates performance. At Ultra settings, the drop from 158.0 FPS at 1080p to 101.0 FPS at 1440p is 36.1%, and 4K Ultra falls to 56.2 FPS, a 64.4% decline from 1080p.

The data indicates that the RTX 3070's 8 GB GDDR6 memory and 448.0 GB/s bandwidth are sufficient for 1080p and 1440p, but 4K pushes the GPU to its limits. The frame rate differences between resolution steps are consistent and large, confirming that Doom's rendering load scales nearly linearly with pixel count. There is no evidence of CPU bottlenecking: the Ryzen 9 5900X, with its 12 cores and 24 threads boosting to 4.80 GHz, maintains high frame rates even at 1080p where CPU overhead is typically most visible.

Settings Recommendations

The measured FPS rows show that Medium settings offer the best balance for high refresh rate gaming. At 1080p Medium, the combo achieves 222.6 FPS, which is 18.4% higher than High's 187.9 FPS and only 14.1% lower than Low's 259.1 FPS. The visual quality improvement from Low to Medium is substantial in Doom, while the performance cost is modest. At 1440p Medium, 146.4 FPS remains comfortably above 120 FPS, making it ideal for 144 Hz displays. High at 1440p still delivers 121.3 FPS, so users with 120 Hz monitors can opt for High.

For 4K gaming, Ultra settings produce 56.2 FPS, which is playable but below the 60 FPS threshold. Dropping to High yields 70.1 FPS, a 24.7% improvement over Ultra, while Medium reaches 80.4 FPS. Low at 4K hits 91.3 FPS, but the visual compromise is significant. The data suggests that High is the recommended preset for 4K, as it maintains playable frame rates while preserving most graphical fidelity. At 1080p and 1440p, Medium or High are both viable; Ultra at these resolutions still produces 158.0 FPS and 101.0 FPS respectively, so competitive players may prefer the lower presets for maximum frame rates.

GPU Role

The NVIDIA GeForce RTX 3070 features 8 GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s of bandwidth. Its base clock runs at 1500 MHz with a boost clock of 1725 MHz. The GPU's 5888 shading units and 96 ROPs handle Doom's geometry and pixel work efficiently, as evidenced by the high frame rates across all measured configurations. The 20.31 TFLOPS FP32 compute performance is the key driver for the game's lighting and particle effects.

In Doom, the GPU's role becomes increasingly dominant as resolution rises. The 4K Ultra result of 56.2 FPS shows the RTX 3070's limits when pushed to maximum settings at 3840x2160. The difference between 4K Low (91.3 FPS) and 4K Ultra (56.2 FPS) is 38.5%, indicating that the Ultra preset's additional effects tax the GPU heavily. The RTX 3070's 72nd percentile ranking among all GPUs confirms its position as a strong mainstream performer, but not a top-tier 4K card. Its nearest rivals include the AMD Radeon RX 6600 XT (0.9% faster) and the NVIDIA GeForce GTX 980 Ti (1.0% faster), showing that the RTX 3070's performance sits in a competitive mid-range bracket.

How This Combo Ranks

The AMD Ryzen 9 5900X paired with the NVIDIA GeForce RTX 3070 ranks 777th out of 1681 tested combos in Doom, placing it in the 46.2nd percentile. This mid-pack ranking reflects the GPU's mid-range positioning rather than any CPU limitation. The combo outperforms roughly half of all tested systems, which is expected given the RTX 3070's 72nd percentile GPU ranking and the Ryzen 9 5900X's 90th percentile CPU ranking.

The discrepancy between the CPU's high percentile (90) and the combo's mid-pack rank (777/1681) indicates that Doom's performance is heavily GPU-bound. The Ryzen 9 5900X's strong multi-threaded capabilities, shown by its 10075 score in 3dmark_max_threads and 33150 in cinebench_r23_multicore, do not translate to higher frame rates when the GPU is the bottleneck. The combo's rank suggests that systems with faster GPUs but weaker CPUs would likely outperform it in Doom, despite the Ryzen 9 5900X's superior processing power.

• 3840x2160 High: 70.1 FPS
• 3840x2160 Ultra: 56.2 FPS

The data shows a consistent hierarchy: Low > Medium > High > Ultra at every resolution. The gap between Low and Ultra is largest at 1080p (101.1 FPS difference) and narrowest at 4K (35.1 FPS difference), indicating that the GPU's performance ceiling compresses the range at higher resolutions.

CPU Role

The AMD Ryzen 9 5900X, built on TSMC's 7 nm process with Zen 3 architecture, provides 12 cores and 24 threads with a 64 MB L3 cache. Its boost clock of 4.80 GHz and single-thread score of 4680 in cinebench_r23_singlecore ensure that Doom's main thread has ample processing power. The CPU's 90th percentile ranking among all CPUs, with an average benchmark score of 39453, places it well above the GPU's 72nd percentile.

However, the measured frame rates demonstrate that the CPU is not the limiting factor in Doom. At 1080p Low, the system achieves 259.1 FPS, which is likely near the game engine's rendering ceiling for this GPU. The CPU's multi-threaded performance, evidenced by 33150 in cinebench_r23_multicore and 39002 in passmark_multithread, is far beyond what Doom requires. The nearest CPU rivals — the AMD EPYC 4245P (0.2% faster), Intel Core i7-13700F (0.9% faster), and Intel Core i7-13700 (1.0% faster) — all show similar performance, confirming that the Ryzen 9 5900X is not a bottleneck.

The CPU's 105 W TDP and dual-channel DDR4 memory support at 51.2 GB/s are adequate for feeding the GPU's 448.0 GB/s bandwidth. The PCIe Gen 4 interface provides sufficient data transfer rates for the RTX 3070. In summary, the Ryzen 9 5900X's role in Doom is to provide consistent frame delivery without stutters, while the RTX 3070 determines overall performance levels based on resolution and settings.
