Doom

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4070 combination delivers a robust performance profile in Doom, with the data indicating a system that is heavily GPU-bound at higher resolutions but capable of exceptional frame rates at 1080p. The measured results show a clear hierarchy where the CPU’s substantial multi-threaded capabilities are sufficient to keep the RTX 4070 well-fed across most settings, with the GPU’s rendering limits becoming the primary constraint as resolution and graphical fidelity increase.

Resolution Scaling

The performance scaling from 1080p to 4K reveals a classic GPU-bound progression, with frame rates dropping significantly as pixel count increases. At 1080p with Low settings, the system achieves an average of 313.1 FPS, which drops to 205.4 FPS at 1440p and further to 109.9 FPS at 4K. This represents a 64.9% reduction in frame rate from 1080p Low to 4K Low, indicating that the GPU is the limiting factor even at the lowest settings where CPU overhead would typically be more prominent.

The scaling pattern becomes more pronounced at higher settings. With Ultra settings, the frame rate falls from 190.8 FPS at 1080p to 124.4 FPS at 1440p, and finally to 63.8 FPS at 4K. The drop from 1440p to 4K at Ultra settings is particularly steep, with a 48.7% reduction, suggesting that the RTX 4070’s memory bandwidth and shading capabilities are being saturated at 4K Ultra. The data shows that the 1440p resolution is the sweet spot for this combo, where the CPU’s 12 cores and 24 threads can still push high frame rates while the GPU maintains playable performance across all settings.

The difference between Low and Ultra settings at each resolution highlights the GPU’s workload scaling. At 1080p, the gap between Low and Ultra is 122.3 FPS, while at 4K, the same gap narrows to 46.1 FPS. This compression at higher resolutions indicates that the GPU is becoming the bottleneck, as the relative cost of additional pixel shading and texture work grows faster than the CPU’s ability to feed the render pipeline. Benchmark results suggest that the Ryzen 9 9900X, with its Zen 5 architecture and boost clock of 5.60 GHz, is never the limiting factor in this game, even at 1080p Low where frame rates exceed 300 FPS.

GPU Role

The NVIDIA GeForce RTX 4070 plays a decisive role in determining the final frame rates, particularly at higher resolutions and settings. The GPU’s 12 GB of GDDR6X memory, operating at 21 Gbps effective with a 192-bit bus, provides a bandwidth of 504.2 GB/s. This memory configuration is sufficient for Doom at all tested resolutions, as the data shows no anomalous frame rate collapses that would indicate memory capacity or bandwidth exhaustion, even at 4K Ultra where average FPS remains at 63.8.

The GPU’s boost clock of 2475 MHz and base clock of 1920 MHz, combined with 5888 shading units, drive the rendering performance. The texture rate of 455.4 GTexel/s and pixel rate of 158.4 GPixel/s are key metrics that explain the performance cliff observed at 4K Ultra. The FP32 throughput of 29.15 TFLOPS is the theoretical ceiling, but the measured FPS data indicates that the GPU is consistently operating near its practical limits at 4K, with the Ultra setting resulting in a 20.6% reduction in frame rate compared to High settings at the same resolution.

The GPU’s positioning relative to its peers, as indicated by its 81st percentile ranking among all GPUs, suggests that it is a mid-to-high-tier performer. The nearest rivals, including the AMD Radeon RX Vega 56 with a deltaPct of -0.6 and the NVIDIA GeForce MX570 A at -1.9, show that the RTX 4070 is closely matched with these alternatives in synthetic benchmarks, though the measured Doom results demonstrate that its real-world performance is well-suited for high-refresh-rate gaming. The GPU’s end-of-life production status and Ada Lovelace architecture with 46 RT cores and 184 tensor cores provide the feature set necessary for modern rendering techniques, though the game’s 2016 release means these features are not fully utilized in this title.

How This Combo Ranks

The combination of the AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4070 ranks 451st out of 1681 tested combos in Doom, placing it in the 73rd percentile of all possible pairings. This ranking reflects a balanced system where the CPU’s high average benchmark score of 54450, which places it in the 94th percentile among all CPUs, is paired with a GPU that ranks in the 81st percentile. The combination’s ranking suggests that while individual components are strong, there are many pairings with faster GPUs that can achieve higher frame rates in this GPU-bound title.

The CPU’s nearest rivals provide context for its performance contribution. The AMD Ryzen 9 9900X3D has an average score of 54681, which is 0.4% higher than the 9900X, while the Intel Core i7-14700F lags by 0.7% with a score of 54097. These minor differences in synthetic benchmarks are unlikely to translate into meaningful frame rate variations in Doom, given that the CPU is not the bottleneck at any tested resolution. The GPU’s rivals show a similar pattern, with the RTX 4070’s average score of 37283 being 0.6% lower than the AMD Radeon RX Vega 56’s 37507 and 1.9% lower than the NVIDIA GeForce MX570 A’s 38008.

The 451st ranking out of 1681 combos indicates that the system is in the top 27% of all pairings tested, which is a strong result considering the GPU’s mid-tier positioning. The data shows that the combo is better suited for 1440p gaming, where it achieves frame rates above 124 FPS at all settings, rather than 4K Ultra where it dips below 64 FPS. This ranking analysis suggests that users seeking higher 4K performance would need to pair the CPU with a more powerful GPU, while those prioritizing 1080p or 1440p esports-style play would find this combination well-optimized.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all settings. Low settings produce an average of 313.1 FPS, Medium reaches 271.1 FPS, High achieves 228.5 FPS, and Ultra still maintains 190.8 FPS. The frame rate differences between settings at 1080p are substantial, with a 122.3 FPS gap between Low and Ultra, indicating that the GPU has ample headroom to accommodate increasing graphical demands without dropping below the 190 FPS threshold.

Moving to 2560x1440, the performance remains strong but shows the expected scaling. Low settings average 205.4 FPS, Medium reaches 175.7 FPS, High achieves 147.5 FPS, and Ultra drops to 124.4 FPS. The gap between Low and Ultra at 1440p narrows to 81.0 FPS, reflecting the increased GPU workload at higher resolutions. All settings at 1440p remain above 124 FPS, making this resolution the most versatile for high-refresh-rate monitors.

At 3840x2160, the GPU becomes the clear limiting factor. Low settings average 109.9 FPS, Medium reaches 98.7 FPS, High achieves 80.4 FPS, and Ultra drops to 63.8 FPS. The scaling from 1440p to 4K shows a 46.5% reduction in frame rate at Low settings and a 48.7% reduction at Ultra settings. The 4K Ultra result of 63.8 FPS is the only configuration tested that falls below the 80 FPS threshold, indicating that this combo is best suited for 4K gaming at Medium settings or lower, where frame rates remain above 98 FPS.
