Doom

Resolution Scaling

The measured frame rates across 1080p, 1440p, and 4K reveal a clear and expected scaling pattern for this combination. At 1080p with Low settings, the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 3070 Ti deliver 270.2 FPS. Moving to 1440p Low drops that to 174.5 FPS, a reduction of roughly 35%. At 4K Low, the average falls further to 93.2 FPS. This steep decline as resolution climbs indicates that the GPU is becoming the primary limiting factor, even at the lowest settings where the CPU has less geometry and draw-call overhead to manage.

The pattern becomes more pronounced when examining the High and Ultra presets. At 1080p High, the pair produces 200 FPS, while 1440p High yields 127.4 FPS and 4K High settles at 71.6 FPS. The Ultra preset shows the most dramatic scaling: 164.9 FPS at 1080p, 105.4 FPS at 1440p, and only 54.8 FPS at 4K. The gap between 1080p and 4K Ultra represents a 66.7% performance drop, which strongly suggests that the RTX 3070 Ti's 8 GB of GDDR6X memory and 256-bit bus are being saturated by the higher resolution's increased pixel and texture demands.

Interestingly, the delta between Low and Ultra at each resolution is substantial. At 1080p, the spread is 105.3 FPS (270.2 vs 164.9). At 1440p, the spread narrows to 69.1 FPS (174.5 vs 105.4). At 4K, the spread tightens further to 38.4 FPS (93.2 vs 54.8). This compression indicates that as resolution increases, the GPU's raw shading and memory bandwidth become the bottleneck, leaving less headroom for settings to matter. The data points to a system that is well-balanced for high-refresh 1080p and 1440p gaming, but the 4K Ultra result of 54.8 FPS suggests that this combo is not ideally suited for maxed-out 4K play in Doom.

How This Combo Ranks

The combination of the Ryzen 9 5900X and RTX 3070 Ti ranks 677th out of 1,681 tested combos in Doom. This places it in the upper portion of the field, roughly in the 60th percentile of all tested pairings. While not a top-tier elite configuration, a rank of 677 out of 1,681 indicates that this setup delivers above-median performance in this specific title. The data shows a system that is competitive but not dominant, likely due to the RTX 3070 Ti being a mid-high-range GPU rather than a flagship.

Looking at the individual component rankings provides context. The CPU sits at the 90th percentile among all processors, which is a strong showing. The GPU, however, is at the 74th percentile among all graphics cards. The disparity between these two percentile figures suggests that the GPU is the weaker link in this pairing for Doom's workload. The combo's overall rank of 677 out of 1,681 reflects this imbalance — the CPU is capable of feeding the GPU well, but the GPU's absolute performance ceiling limits the final output.

The nearest rival data for the CPU shows it trading blows with other high-end parts. The Ryzen 9 5900X is 0.2% ahead of the AMD EPYC 4245P and 0.9% ahead of the Intel Core i7-13700F in average benchmark scores. It trails the AMD Ryzen 7 PRO 8845HS by 0.7% and the Intel Core i7-13700 by 1%. These tiny margins indicate that the CPU is performing exactly as expected for its class. For the GPU, the RTX 3070 Ti is 0.3% ahead of the AMD Radeon RX 590 GME and 0.9% behind the NVIDIA Quadro M5000, with similar small deltas against the RX 6700 and GRID M60-1Q. These negligible differences reinforce that the GPU's performance is firmly within its expected band.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture with a GA104 chip manufactured on Samsung's 8 nm process. It houses 17,400 million transistors on a 392 mm² die, giving a transistor density of 44.4M per mm². The card operates with a base clock of 1575 MHz and a boost clock of 1770 MHz. Memory runs at 1188 MHz, translating to 19 Gbps effective on the 8 GB GDDR6X frame buffer. The 256-bit memory bus provides a bandwidth of 608.3 GB/s, which is critical for Doom's texture-heavy environments at high resolutions.

The GPU's compute resources are substantial: 6,144 shading units, 192 texture mapping units, and 96 raster output units. It also includes 48 ray tracing cores and 192 tensor cores, though Doom (2016) does not leverage ray tracing. The pixel rate is 169.9 GPixel/s, and the texture rate is 339.8 GTexel/s. Floating point performance is rated at 21.75 TFLOPS for both FP32 and FP16 (1:1). These specifications place the card in a solid mid-to-high tier, and the benchmark results bear this out — the GPU holds a 74th percentile rank among all GPUs, with an average benchmark score of 30,849.

In Doom specifically, the GPU's role is decisive. The 4K Ultra result of 54.8 FPS is the lowest measured value in the entire dataset, and it highlights the card's limitations when pushed to maximum settings at 4K. The 8 GB VRAM capacity is a potential constraint here, as Doom's Ultra settings at 2160p can consume significant memory. The measured FPS at 4K High (71.6) and 4K Medium (82.3) show that reducing settings from Ultra to High yields a 30.7% improvement, while dropping to Medium adds another 14.9% over High. This suggests that the card is memory-bandwidth or fill-rate limited at 4K Ultra, and that users can recover playable frame rates by stepping down one or two settings levels.

Measured FPS Breakdown

The complete measured FPS dataset provides a detailed picture across three resolutions and four settings levels. At 1920x1080, the combo delivers 270.2 FPS on Low, 239.3 FPS on Medium, 200 FPS on High, and 164.9 FPS on Ultra. The step from Low to Medium costs 30.9 FPS, Medium to High costs 39.3 FPS, and High to Ultra costs 35.1 FPS. These are relatively even steps, indicating that at 1080p the GPU has enough headroom that each settings tier imposes a similar incremental load.

At 2560x1440, the numbers are 174.5 FPS on Low, 154.7 FPS on Medium, 127.4 FPS on High, and 105.4 FPS on Ultra. The transition from Low to Medium is a modest 19.8 FPS drop, but Medium to High represents a more significant 27.3 FPS loss. High to Ultra costs another 22 FPS. The 1440p results show that the card remains very capable, with even the Ultra preset exceeding 100 FPS.

At 3840x2160, the data shows 93.2 FPS on Low, 82.3 FPS on Medium, 71.6 FPS on High, and 54.8 FPS on Ultra. The Low to Medium drop is 10.9 FPS, Medium to High is 10.7 FPS, and High to Ultra is 16.8 FPS. The larger penalty for the Ultra preset at 4K reinforces the earlier observation that this setting pushes the GPU past a comfortable operating point. For 4K gaming, the Low setting remains smooth at 93.2 FPS, but users targeting 60 FPS or higher will need to stay at High or below, as Ultra falls short of that threshold.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, codenamed Vermeer. It uses the AMD Socket AM4 platform and is built on TSMC's 7 nm process with 8,300 million transistors across a dual-chiplet design with a 2x 74 mm² die size. The base clock is 3.70 GHz with a boost clock of 4.80 GHz. The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a large 64 MB L3 cache. Memory support is DDR4 with dual-channel configuration and a bandwidth of 51.2 GB/s. The CPU supports PCIe Gen 4 and has a 105 W TDP.

In Doom, the CPU's role is less prominent than the GPU's, but still measurable. The 1080p Low result of 270.2 FPS is the highest in the dataset, and it is likely approaching the point where CPU limitations begin to emerge. The 12 cores and 24 threads provide ample parallelism for the game's engine, and the high boost clock of 4.80 GHz ensures strong single-thread performance, which is often more critical in older titles like Doom (released in 2016). The CPU's percentile rank of 90 among all processors confirms that it is a top-tier performer.

Benchmark scores further illustrate the CPU's capabilities. In Cinebench R23, it scores 33,150 in multi-core and 4,680 in single-core. Geekbench results show 11,877 multi-core and 2,202 single-core. The 3DMark scores scale from 941 in single-thread to 10,075 in max threads, demonstrating effective scaling across the 12-core configuration. PassMark scores include 390,002 in multithread and 3,469 in single-thread. These figures place the CPU in the 90th percentile, with an average benchmark score of 39,453.

The nearest rivals for the CPU all sit within a 1% delta of its average score. The AMD EPYC 4245P is 0.2% ahead, the AMD Ryzen 7 PRO 8845HS is 0.7% behind, the Intel Core i7-13700F is 0.9% behind, and the Intel Core i7-13700 is 1% behind. This clustering indicates that the Ryzen 9 5900X is performing exactly at its expected level. For Doom, the CPU's contribution is to ensure that frame rates remain high even at 1080p Low, where the 270.2 FPS result shows no obvious CPU bottleneck. The data suggests that this processor is more than sufficient for this game, and that the RTX 3070 Ti is the component that ultimately dictates the combo's rank of 677 out of 1,681.
