Doom

The AMD Ryzen 9 5900X and NVIDIA GeForce RTX 5070 Ti combination delivers exceptionally high frame rates in Doom, with performance scaling predictably as resolution increases. The data shows a system that is overwhelmingly GPU-bound at lower resolutions, transitioning to a more balanced load at 4K where the GPU's capabilities are fully exercised.

Resolution Scaling

The frame rate progression across resolutions reveals a classic GPU-limited scenario. At 1920x1080, the combo achieves a staggering 363 FPS on Low settings, which drops to 245 FPS at 2560x1440 and further to 133 FPS at 3840x2160. This represents a 63% reduction in frame rate from 1080p to 4K on Low settings, indicating that the GPU is the primary bottleneck even at lower resolutions where the CPU could theoretically push more frames.

The scaling pattern becomes more nuanced at higher quality presets. On Ultra settings, the frame rate goes from 227 FPS at 1080p to 147 FPS at 1440p and finally to 80 FPS at 4K. The percentage drop from 1080p to 4K on Ultra is 65%, nearly identical to the Low preset drop. This consistency suggests that the RTX 5070 Ti's rendering pipeline is being saturated uniformly across all quality levels, with the 16 GB GDDR7 memory buffer and 896.0 GB/s bandwidth handling the increased pixel count without introducing memory-related stutters.

The gap between Low and Ultra settings widens as resolution decreases. At 4K, the difference between Low and Ultra is 53 FPS (133 vs 80), while at 1080p it expands to 136 FPS (363 vs 227). This behavior indicates that at lower resolutions, the GPU has spare compute headroom that quality settings can consume, but at 4K the pixel fill rate becomes the limiting factor regardless of how many shading units are active. The 43.94 TFLOPS FP32 throughput and 235.4 GPixel/s pixel rate are the key metrics driving this scaling.

GPU Role

The RTX 5070 Ti's memory configuration plays a critical role in Doom's performance. With 16 GB of GDDR7 memory on a 256-bit bus, the GPU delivers 896.0 GB/s of bandwidth. This is particularly relevant because the measured FPS data shows no min FPS values below the average for most presets, suggesting the memory subsystem is not causing frame time spikes. The Medium preset at 4K shows a min FPS of 98 and max of 133, perfectly matching the Low preset average, which indicates consistent memory throughput even when texture detail increases.

The GPU's clock behavior is equally important. The base clock of 2295 MHz and boost clock of 2452 MHz are relatively close, which implies the card maintains stable performance under sustained load. The 300 W TDP and dual-slot cooling solution allow these clocks to persist during extended gaming sessions, as evidenced by the consistent average FPS numbers across repeated measurements. The Blackwell 2.0 architecture's 96 ROPs and 280 TMUs provide the texture and pixel processing necessary for Doom's fast-paced rendering demands.

The GPU's percentile ranking of 86 among all GPUs, with an average benchmark score of 49957, places it in the upper tier of graphics cards. Its nearest rival, the AMD Radeon RX Vega 64, scores 50001 with a deltaPct of -0.1%, while the AMD Radeon RX 6900 XT scores 50951 with a -2% delta. This statistical proximity to older flagship cards underscores that the RTX 5070 Ti's advantage in Doom comes from its architectural efficiency rather than raw compute superiority.

Settings Recommendations

Analyzing the measured FPS data, the Medium preset emerges as the optimal balance between visual fidelity and performance. At 4K, Medium delivers 115 FPS, which is 18% higher than High and 44% higher than Ultra. The min FPS of 98 at Medium 4K ensures that even the most demanding scenes stay above 60 FPS, making this preset ideal for high-refresh-rate 4K displays. The jump from Medium to High costs 17 FPS at 4K, while the jump from High to Ultra costs an additional 18 FPS, showing diminishing returns at the top end.

At 1440p, the Medium preset's 213 FPS average with a 181 min FPS provides a smooth experience for 144 Hz monitors. The Low preset at 245 FPS offers minimal visual benefit over Medium for competitive play, while the Ultra preset's 147 FPS still exceeds most 1440p display refresh rates. The 1080p results show that even Ultra settings at 227 FPS are far above any current monitor's refresh rate, so users with 1080p displays can safely max out all settings without concern.

The data suggests that the sweet spot for this combo is Medium at 4K or Ultra at 1440p, depending on display capabilities. The Medium preset's consistent min/max FPS spread (98-133 at 4K, 181-245 at 1440p, 280-379 at 1080p) indicates stable frame pacing, whereas the High and Ultra presets lack reported min/max values, potentially hiding more variance.

Measured FPS Breakdown

At 3840x2160, the performance hierarchy is clear: Low delivers 133 FPS, Medium 115 FPS (with a min of 98 and max of 133), High 98 FPS, and Ultra 80 FPS. The progression from Low to Ultra represents a 40% reduction in frame rate, with each step up in quality costing roughly 15-18 FPS. The Medium preset's max FPS matching the Low average suggests that the GPU can occasionally hit lower-preset performance even with higher settings, indicating headroom in certain scenes.

The 2560x1440 results show a similar pattern with higher absolute numbers: Low at 245 FPS, Medium at 213 FPS (min 181, max 245), High at 180 FPS, and Ultra at 147 FPS. The Medium preset's max FPS again equals the Low average, reinforcing the observation that Doom's quality settings primarily affect average load rather than peak capability. The 35% gap between Low and Ultra at 1440p is slightly smaller than at 4K, reflecting the GPU's increased compute headroom at this resolution.

At 1920x1080, the combo produces exceptional numbers: Low at 363 FPS, Medium at 329 FPS (min 280, max 379), High at 278 FPS, and Ultra at 227 FPS. The 1080p Medium max FPS of 379 actually exceeds the Low average, which is the only instance across all resolutions where this occurs. This anomaly suggests that at 1080p, the CPU's 12 cores and 24 threads are sufficient to feed the GPU even with higher settings, and the frame rate is genuinely GPU-limited rather than CPU-bound.

How This Combo Ranks

The AMD Ryzen 9 5900X + NVIDIA GeForce RTX 5070 Ti combination ranks 388th out of 3712 tested combos in Doom, placing it in the top 10.5% of all configurations. This ranking reflects the CPU's 87th percentile score among all processors, with an average benchmark score of 41376, paired with the GPU's 86th percentile score of 49957. The combination of two top-decile components yields a result that is better than either component's individual percentile, suggesting synergistic performance in this title.

The CPU's nearest rivals show how close the 5900X is to its competition. The Intel Core Ultra 7 366H scores 41263 with a deltaPct of 0.3%, while the Intel Core i7-14650HX scores 41576 with a deltaPct of -0.5%. This means the 5900X is statistically tied with these processors in synthetic benchmarks, yet the overall combo ranking in Doom benefits from the GPU's strong showing. The GPU's nearest rivals tell a similar story: the RX Vega 64 is 0.1% faster, the Arc A550M is 0.4% slower, and the RX 6900 XT is 2% faster in average score.

The rank of 388 out of 3712 is particularly impressive considering that Doom is a 2016 title that favors high clock speeds and strong single-thread performance. The 5900X's boost clock of 4.80 GHz and the RTX 5070 Ti's high pixel rate combine to produce frame rates that exceed what most modern systems achieve in this game.
