Doom

The AMD Ryzen 9 5900X pairs a 12-core, 24-thread Zen 3 architecture with a 3.70 GHz base clock and a 4.80 GHz boost clock. For a 2016-era FPS like Doom, this configuration is overwhelmingly sufficient. The CPU’s single-thread performance, reflected in a 3DMark single-thread score of 941 and a Cinebench R23 single-core score of 4680, ensures that game logic and draw calls are processed with minimal latency. The 64 MB of L3 cache further reduces memory access delays, which is critical for maintaining consistent frame pacing in fast-paced combat scenarios.

The data shows that the CPU’s multi-threaded capabilities are largely underutilized in this title. While the processor posts a Cinebench R23 multi-core score of 33150, Doom’s engine does not scale linearly with thread count beyond a certain point. The benchmark results indicate that the 5900X sits in the 90th percentile among all CPUs, with an average benchmark score of 39453. Compared to its nearest rivals, the processor is virtually tied with the AMD EPYC 4245P (0.2% delta) and the Intel Core i7-13700F (0.9% delta), while trailing the AMD Ryzen 7 PRO 8845HS by 0.7% and the Intel Core i7-13700 by 1%. This near-parity suggests that in Doom, the CPU is never the limiting factor; its job is to feed the GPU efficiently, and it does so without breaking a sweat.

GPU Role

The NVIDIA GeForce RTX 4070 Ti is the dominant component in this pairing. Built on the Ada Lovelace architecture with a 5 nm process, the GPU features 12 GB of GDDR6X memory on a 192-bit bus, delivering a bandwidth of 504.2 GB/s. Its boost clock of 2610 MHz, combined with 7680 shading units, provides the raw compute necessary to push high frame rates at demanding resolutions. The GPU’s 40.09 TFLOPS of FP32 performance is the engine driving Doom’s rendering, and the benchmark results confirm its strength.

The RTX 4070 Ti ranks in the 85th percentile among all GPUs, with an average benchmark score of 44900. Its nearest rivals show a tight cluster: the NVIDIA GeForce RTX 5090 Mobile is 0.6% ahead, while the Intel Arc A730M trails by 1.5% and the AMD Radeon Pro 580 is 1.6% behind. This positioning indicates that the 4070 Ti is a high-end part, but its performance in Doom is more about the game’s optimization for NVIDIA hardware than about raw benchmark scores. The GPU’s 12 GB VRAM is ample for Doom’s textures, even at 4K, and the memory bandwidth ensures that texture streaming does not cause hitches. In this context, the GPU is clearly the primary driver of FPS, as the CPU is more than capable of keeping up.

Resolution Scaling

The FPS data reveals a classic GPU-bound scaling pattern. Moving from 1920x1080 to 2560x1440 and then to 3840x2160 shows a consistent drop in average FPS across all settings, which is expected when the GPU becomes the bottleneck. At 1080p, the CPU and GPU work in tandem to produce extremely high frame rates, but as resolution increases, the pixel fill rate and shading demands grow, shifting the load entirely onto the GPU.

At Ultra settings, the drop from 1080p to 1440p is a reduction of 79.2 FPS (from 223.9 to 144.7), and the further drop from 1440p to 4K is 65.7 FPS (down to 79). This steep decline indicates that the RTX 4070 Ti, while powerful, is not sufficient to maintain high refresh rates at 4K with maximum settings. Conversely, at Low settings, the 1080p average of 363.3 FPS is so high that the CPU’s single-thread performance becomes more relevant, but even then, the 4K Low average of 127.1 FPS shows that the GPU still dominates the frame time budget. The pattern is clear: the limiting component at higher resolutions is the GPU, while at 1080p, the system approaches a balanced state where both components are near their limits.

Measured FPS Breakdown

The measured FPS data provides a detailed picture of performance across resolutions and settings. At 1920x1080, the RTX 4070 Ti delivers exceptional frame rates. Low settings yield an average of 363.3 FPS, Medium drops to 320.9 FPS, High to 268.6 FPS, and Ultra to 223.9 FPS. These numbers indicate that at 1080p, the system is capable of driving high-refresh-rate monitors (240Hz or above) even with maximum settings, though the gap between Low and Ultra is significant, showing a 139.4 FPS difference.

Moving to 2560x1440, the averages are still impressive but show a clear performance tax. Low settings produce 240.2 FPS, Medium 205.5 FPS, High 177.6 FPS, and Ultra 144.7 FPS. The Ultra setting at 1440p is the first point where the frame rate drops below the 144Hz threshold, indicating that users seeking maximum visual fidelity at this resolution may need to accept lower refresh rates. At 3840x2160, the GPU’s limits become apparent. Low settings average 127.1 FPS, Medium 111.8 FPS, High 93.3 FPS, and Ultra 79 FPS. These numbers show that 4K gaming is viable but not at high refresh rates; even at Low settings, the average FPS is below 130, and Ultra settings dip below 80 FPS.

The scaling between settings is also informative. At 1080p, the difference between Low and Ultra is 139.4 FPS, which represents a 38.4% reduction in performance. At 1440p, the same comparison yields a 95.5 FPS drop (39.8%), and at 4K, it is 48.1 FPS (37.9%). This consistency suggests that the relative cost of increasing settings is stable across resolutions, reinforcing that the GPU is the primary constraint.

How This Combo Ranks

In the database of tested combinations, this pairing of the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 4070 Ti ranks 213th out of 1681 combos for Doom. This places it in the top 12.7% of all tested systems, which is a strong result for a high-end desktop configuration. The rank reflects the overall balance of the system: the CPU is not a bottleneck, and the GPU provides substantial headroom for the game’s requirements.

The combination’s rank is influenced by the fact that Doom is a well-optimized title that favors high clock speeds and strong single-thread performance, which the 5900X provides, alongside the raw pixel-pushing power of the 4070 Ti. The data indicates that this system outperforms the vast majority of tested combos, but it is not at the absolute top, where configurations with more powerful GPUs (like the RTX 5090 Mobile, which is a close rival) or newer CPUs might edge it out. The 213th rank suggests that while this is a capable gaming rig, there is headroom for improvement, particularly at 4K Ultra settings where the GPU’s limitations are most evident. For users targeting 1080p or 1440p with high refresh rates, this combo is exceptionally well-suited, as the measured FPS data confirms. The rank, combined with the FPS breakdown, provides a clear picture: this is a high-performing system that excels at mainstream resolutions but shows its limits at 4K with maximum settings.
