Doom

Settings Recommendations

For Doom, the measured data reveals a clear hierarchy across the four tested presets. At 3840x2160, the High preset delivers 114.5 fps, which is a substantial 24% improvement over the Ultra preset's 92.3 fps. The Low preset at this resolution reaches 155.7 fps, while Medium sits at 138.2 fps. The gap between High and Ultra is particularly noteworthy—dropping from High to Ultra costs 22.2 fps, a reduction that pushes the experience below the 100 fps threshold that many high-refresh displays target.

At 2560x1440, the pattern shifts. High produces 210.8 fps, Medium achieves 249.5 fps, and Low reaches 290.5 fps. Ultra trails at 172.4 fps. The delta between High and Medium here is 38.7 fps, meaning users can gain nearly 40 fps by stepping down one preset level. At 1920x1080, the differences become even more pronounced: High yields 328.1 fps, Medium hits 388.6 fps, Low peaks at 441.2 fps, and Ultra manages 265.5 fps.

The optimal experience per the measured rows depends on the display refresh rate. For 3840x2160 panels capped at 120 Hz, the High preset is the best balance, delivering 114.5 fps—just shy of the cap but far smoother than Ultra's 92.3 fps. At 2560x1440 with 240 Hz displays, the Medium preset's 249.5 fps nearly saturates the refresh ceiling, whereas High's 210.8 fps leaves headroom unutilized. For 1920x1080 gaming, the Medium preset's 388.6 fps provides an enormous cushion for any refresh rate, and even High at 328.1 fps is sufficient for 300 Hz+ panels. Ultra, in every resolution, represents the worst performance-per-frame tradeoff among the four presets, with the largest absolute drops relative to High: 22.2 fps at 4K, 38.4 fps at 1440p, and 62.6 fps at 1080p.

GPU Role

The NVIDIA GeForce RTX 4090 is the dominant component in this pairing, and its specifications directly explain the measured FPS trends. The GPU's 24 GB of GDDR6X memory on a 384-bit bus provides 1.01 TB/s of bandwidth. This memory configuration is crucial for Doom's texture streaming at high resolutions—the 24 GB capacity ensures that even the Ultra preset's asset demands at 3840x2160 do not cause memory pressure, as evidenced by the fact that the GPU still manages 92.3 fps at that demanding setting.

The clock behavior is equally telling. The RTX 4090's base clock of 2235 MHz and boost clock of 2520 MHz, combined with its 16384 shading units, produce a pixel rate of 443.5 GPixel/s and a texture rate of 1,290.2 GTexel/s. These raw throughput figures explain why the GPU scales almost linearly with decreasing resolution: from 92.3 fps at 4K Ultra to 265.5 fps at 1080p Ultra, a 2.88x increase in frame rate for a 4x reduction in pixel count. The FP32 throughput of 82.58 TFLOPS ensures that the GPU is never the bottleneck in Doom's Vulkan-rendered scenes, even at 441.2 fps on the Low preset at 1080p.

The GPU's benchmark data corroborates its position: a Passmark G3D score of 38194 and a 3DMark Steel Nomad DX12 score of 9223 place it in the 91st percentile among all GPUs. Its nearest rivals in average benchmark score include the NVIDIA Tesla T4 (delta -0.4%), Tesla P40 (delta +0.5%), and AMD Radeon Pro Vega 56 (delta -0.9%), though these are compute-oriented cards rather than gaming-focused counterparts. The RTX 4090's end-of-life production status and 450 W TDP indicate it is a top-tier part that remains relevant for this title's demanding frame rates.

How This Combo Ranks

The combination of the AMD Ryzen 7 7700X and NVIDIA GeForce RTX 4090 achieves rank 25 out of 1681 tested combos in Doom. This places the pairing in the top 1.5% of all configurations in the database, which is consistent with the individual component rankings. The CPU sits in the 89th percentile among all processors with an average benchmark score of 34313, while the GPU holds the 91st percentile with an average score of 66473.

The CPU's nearest rivals provide context for its contribution. The Intel Core i5-13500 scores 34175 (delta +0.4% relative to the 7700X), the Intel Core i7-12800HX scores 34136 (delta +0.5%), the Intel Core Ultra 7 165H scores 34584 (delta -0.8%), and the AMD EPYC 4244P scores 34599 (delta -0.8%). These deltas are all within 1%, meaning the 7700X is effectively performance-equivalent to a broad swath of modern mid-range and high-end CPUs in synthetic workloads. For Doom specifically, however, the combo rank of 25 out of 1681 suggests that the GPU's raw power is the primary driver of the excellent placement, since the CPU's multi-threaded scores (Cinebench R23 multicore of 30325, Geekbench multicore of 15538) are strong but not class-leading.

The GPU's nearest rivals in average benchmark score show a similar clustering: the Tesla T4 at 66733 (delta -0.4%), Tesla P40 at 66127 (delta +0.5%), Radeon Pro Vega 56 at 67097 (delta -0.9%), and Quadro P6000 at 67320 (delta -1.3%). These are professional cards, not gaming GPUs, which highlights that the RTX 4090's gaming performance in Doom is measured directly rather than inferred from synthetic benchmarks. The rank of 25 confirms that this combo outperforms the vast majority of alternatives in the database, with only 24 configurations achieving higher FPS in this title.

Measured FPS Breakdown

At 3840x2160, the RTX 4090 paired with the 7700X delivers 155.7 fps on Low, 138.2 fps on Medium, 114.5 fps on High, and 92.3 fps on Ultra. The progression from Low to Ultra shows a 63.4 fps total drop, with the steepest single-step decline occurring between Medium and High (23.7 fps) and between High and Ultra (22.2 fps). The Low-to-Medium step costs only 17.5 fps, making Medium a relatively efficient upgrade from Low at this resolution.

At 2560x1440, the measured averages are 290.5 fps (Low), 249.5 fps (Medium), 210.8 fps (High), and 172.4 fps (Ultra). The step from Low to Medium costs 41.0 fps, Medium to High costs 38.7 fps, and High to Ultra costs 38.4 fps. These near-uniform deltas indicate that each preset level imposes a consistent computational burden at this resolution. The total spread from Low to Ultra is 118.1 fps, which is proportionally similar to the 4K spread when normalized to frame time.

At 1920x1080, the results scale dramatically: 441.2 fps (Low), 388.6 fps (Medium), 328.1 fps (High), and 265.5 fps (Ultra). The Low-to-Medium drop is 52.6 fps, Medium-to-High is 60.5 fps, and High-to-Ultra is 62.6 fps. This 1080p data reveals that the GPU becomes increasingly pixel-bound at lower resolutions, with the CPU's 8-core, 16-thread configuration (base 4.50 GHz, boost 5.40 GHz) providing sufficient single-thread throughput to feed the GPU even at 441.2 fps. The 3DMark single-thread score of 1090 and Cinebench R23 single-core score of 4281 confirm the CPU's strong per-core performance, which is essential for achieving these extreme frame rates.

Comparing across resolutions, the 1080p Low result (441.2 fps) is 2.83x higher than the 4K Low result (155.7 fps), while the 1080p Ultra result (265.5 fps) is 2.88x higher than the 4K Ultra result (92.3 fps). This consistent scaling factor, close to the theoretical 4x pixel-count ratio, indicates that the RTX 4090's memory bandwidth and shading resources scale efficiently across resolutions without hitting a CPU bottleneck until the very highest frame rates.

FAQ

Q: What is the best preset to use with this combo at 4K?

A: The High preset at 3840x2160 delivers 114.5 fps, which is 22.2 fps higher than Ultra's 92.3 fps. For 120 Hz displays, High provides the closest match to the refresh ceiling while maintaining significantly higher visual quality than Medium's 138.2 fps.

Q: How much performance is lost by enabling the Ultra preset?

A: Across all three resolutions, Ultra imposes a consistent penalty relative to High: 22.2 fps at 4K, 38.4 fps at 1440p, and 62.6 fps at 1080p. The percentage loss is roughly 19-24% depending on resolution, making Ultra the least efficient preset in terms of frame rate per setting step.

Q: Is the RTX 4090's 24 GB VRAM sufficient for Doom at maximum settings?

A: The measured data shows no indication of VRAM-related stuttering or frame drops. The GPU achieves 92.3 fps at 4K Ultra and 265.5 fps at 1080p Ultra, with the 1.01 TB/s bandwidth and 24 GB capacity proving more than adequate for this title's requirements.
