CPU Role

The AMD Ryzen 7 7800X3D is built on the Zen 4 architecture using a 5 nm process, featuring 8 cores and 16 threads. Its base clock of 4.20 GHz and boost clock of 5.00 GHz are paired with a substantial 96 MB of shared L3 cache, a configuration that excels in gaming workloads. The processor's benchmark results show strong single-thread performance with a 3DMark single-thread score of 959 and a Cinebench R23 single-core score of 4115.

In Doom, the CPU's role is predominantly about maintaining high frame rates at lower resolutions where the GPU is not the limiting factor. The data shows that at 1080p Low, the system produces 274.5 FPS, which is 39% higher than the 197.6 FPS at 1080p High. This suggests that even at 1080p High, the CPU is capable of feeding the GPU sufficiently, as the frame rate drops are more attributable to GPU load than CPU limitations. The processor's 3DMark 16-thread score of 7980 and Cinebench R20 multicore score of 12242 indicate robust multi-threaded capabilities that prevent bottlenecking in this well-optimized title.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is an Ampere-architecture GPU built on an 8 nm process, featuring 6144 shading units, 192 texture mapping units, and 96 ROPs. It operates at a base clock of 1575 MHz with a boost clock of 1770 MHz, and its 8 GB of GDDR6X memory on a 256-bit bus delivers 608.3 GB/s of bandwidth. The GPU's FP32 performance is rated at 21.75 TFLOPS, and it supports DirectX 12 Ultimate and Vulkan 1.4.

The GPU's role in Doom becomes increasingly dominant as resolution scales. At 4K Ultra, the average FPS drops to 54.6, which is exactly 66% lower than the 1080p Ultra result of 162.4 FPS. This dramatic scaling indicates that the GPU is the primary constraint at higher resolutions. The RTX 3070 Ti's pixel rate of 169.9 GPixel/s and texture rate of 339.8 GTexel/s are substantial but not sufficient to maintain high frame rates at 4K with maximum settings. The data suggests that 1440p is the GPU's sweet spot for this game, with all settings producing frame rates above 103 FPS.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across three resolutions and four settings levels. At 1920x1080, the system delivers 274.5 FPS on Low, 234.5 FPS on Medium, 197.6 FPS on High, and 162.4 FPS on Ultra. These results show a consistent 17-18% reduction in FPS when moving from Low to Medium, and a further 15-16% reduction from Medium to High. The step from High to Ultra costs another 18% performance.

At 2560x1440, the frame rates are 176.8 FPS on Low, 152.5 FPS on Medium, 128.5 FPS on High, and 103.5 FPS on Ultra. The scaling between settings follows a similar pattern to 1080p, with each step up in quality reducing FPS by approximately 14-16%. At 3840x2160, the results are 92.4 FPS on Low, 82.8 FPS on Medium, 67.6 FPS on High, and 54.6 FPS on Ultra. The gap between Low and Ultra at 4K is 69%, compared to 41% at 1080p, highlighting the increased GPU pressure at higher resolutions.

How This Combo Ranks

The combo ranks 686 out of 1681 tested combinations, placing it in the 59th percentile of all tested combos. This ranking reflects the balanced nature of the pairing: the Ryzen 7 7800X3D sits at the 87th percentile among all CPUs with an average benchmark score of 31580, while the RTX 3070 Ti sits at the 74th percentile among all GPUs with a score of 30849. The CPU's nearest rival is the Intel Core i7-12700F with a deltaPct of 0.1%, indicating near-identical average performance. The GPU's closest competitor is the AMD Radeon RX 6700 with a deltaPct of -0.8%, meaning the RTX 3070 Ti is slightly ahead. This data suggests the combo's rank is more constrained by the GPU than the CPU, as the processor is relatively stronger in its percentile ranking.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For 1080p gaming, the High preset at 197.6 FPS offers an excellent balance of visual quality and performance, easily exceeding the 144 Hz refresh rate common in modern monitors. The Ultra preset at 162.4 FPS still provides a high-refresh experience. At 1440p, the High preset at 128.5 FPS is the recommended choice for smooth gameplay, while the Medium preset at 152.5 FPS is preferable for those prioritizing higher frame rates. The 4K resolution presents a more challenging scenario: the Medium preset at 82.8 FPS is the best compromise, as it maintains a frame rate above 60 FPS while providing better visual fidelity than Low settings. The Ultra preset at 54.6 FPS is only suitable for players who prioritize visuals over smoothness and have a 60 Hz display.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals important insights about the limiting component. At High settings, the frame rates are 197.6 FPS at 1080p, 128.5 FPS at 1440p, and 67.6 FPS at 4K. This represents a 35% drop from 1080p to 1440p and a 66% drop from 1080p to 4K. The scaling is approximately linear with pixel count, which indicates the GPU is the primary bottleneck across these resolutions. At Low settings, the frame rates are 274.5 FPS at 1080p, 176.8 FPS at 1440p, and 92.4 FPS at 4K. The 1080p to 1440p drop is 36%, and the 1080p to 4K drop is 66%, nearly identical to the High settings scaling. This consistency suggests that even at Low settings, the CPU is not the limiting factor at any resolution. The data indicates that the RTX 3070 Ti's performance ceiling is reached at 4K, and the Ryzen 7 7800X3D provides ample headroom to avoid bottlenecking the GPU in Doom.
