Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 9 5950X and AMD Radeon RX 7700 XT reveals a pronounced scaling pattern as resolution increases. At 1920x1080 with Ultra settings, the combo produces 158.3 FPS average. Moving to 2560x1440 Ultra drops this to 99.4 FPS, a reduction of roughly 37%. At 3840x2160 Ultra, the average falls further to 53.8 FPS, which is about 66% below the 1080p Ultra result. This steep decline is characteristic of a GPU-bound scenario at higher resolutions, where the rendering load on the Radeon RX 7700 XT grows faster than the CPU's ability to feed frames.

The scaling from Low to High settings at each resolution reinforces this interpretation. At 1080p Low, the combo reaches 262.7 FPS, while 1080p High yields 193 FPS. The gap between Low and High at 1080p is 69.7 FPS, but at 4K the same settings gap is only 26.8 FPS (94.8 vs 68). This compression of the settings delta at 4K indicates that the GPU is the limiting component there, as the absolute frame rate ceiling is constrained by pixel throughput rather than shader or texture workload scaling. In contrast, the larger absolute deltas at 1080p suggest the CPU has more headroom to push frames when the GPU is less burdened.

The data also shows that the 4K Low result of 94.8 FPS is higher than the 1440p Ultra result of 99.4 FPS by a slim margin, which is counterintuitive at first glance. However, this pattern is consistent with the GPU being the primary bottleneck at both resolutions: reducing settings at 4K alleviates pixel-shading overhead more than dropping resolution at fixed settings, allowing the GPU to catch up. The 1080p Medium result of 230.7 FPS versus 1440p Medium at 147.1 FPS shows a 56.8% uplift from resolution alone, reinforcing that the GPU's fillrate and memory bandwidth are the key constraints as pixel count rises.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture, with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. Its benchmark profile shows strong multi-threaded capability: Cinebench R23 multi-core scores 38607, while single-core scores 5450. The 3DMark 16-thread score of 10810 and max-thread score of 11597 indicate that the CPU scales well with thread count, but Doom's engine is not heavily threaded in a way that would fully utilize 32 threads. The 3DMark 2-thread score of 1856 and 4-thread score of 3595 suggest that the game benefits more from high single-core performance than from raw core count.

In this game's measured results, the CPU's role appears secondary to the GPU at most settings. At 1080p Low, the combo achieves 262.7 FPS, which is likely near the CPU's practical frame delivery limit for this engine. The fact that 1080p Medium (230.7 FPS) and 1080p High (193 FPS) are both lower indicates that the GPU begins to take over as the limiter even at 1080p when settings increase. The Ryzen 9 5950X's single-thread performance, as shown by the Cinebench R20 single-core score of 2289, is sufficient to avoid bottlenecking the RX 7700 XT at lower resolutions, but the data suggests that at 1080p Low, the CPU is still the primary constraint — the 262.7 FPS ceiling is far below what the GPU could theoretically produce if the CPU were not involved.

The CPU's cache hierarchy includes 64 MB of L3 cache, which helps with game-level data locality. The 3DMark 8-thread score of 6598 versus the max-thread score of 11597 shows that doubling threads from 8 to 32 yields only a 75% improvement, indicating diminishing returns for workloads that do not scale perfectly. Doom's frame generation is typically bound by a few main threads, so the 5950X's strength here lies in its high boost clock and IPC rather than its 16-core count. The percentileVsAllCpus of 93 places it in the top tier, and its nearest rival, the Intel Core i5-14600K, has a deltaPct of -0.2, meaning the 5950X is essentially equivalent in average benchmark score (49062 vs 49166). This near-parity suggests that for a game like Doom, the 5950X's extra cores do not translate into a measurable advantage over a newer 6-core part.

GPU Role

The AMD Radeon RX 7700 XT is built on the RDNA 3.0 architecture with the Navi 32 chip, fabricated on a 5 nm process. It features 12 GB of GDDR6 memory on a 192-bit bus, with a bandwidth of 432.0 GB/s. The GPU's clocks are listed as a base of 1435 MHz, a game clock of 2171 MHz, and a boost clock of 2544 MHz. Its compute capabilities include 3456 shading units, 216 TMUs, and 96 ROPs, with a pixel rate of 244.2 GPixel/s and a texture rate of 549.5 GTexel/s. The FP32 throughput is 35.17 TFLOPS, which is substantial for a mid-range card.

The GPU's benchmark scores place it at the 73rd percentile among all GPUs, with an average benchmark score of 30097. Its nearest rival, the NVIDIA GeForce RTX 5060, has a deltaPct of 0, indicating a statistical tie in average score (30109 vs 30097). The AMD Radeon RX 570 also shows a deltaPct of -0.2, which is within noise. This tells us that the RX 7700 XT's raw compute is competitive with those cards, but in Doom specifically, the measured FPS reveals how the GPU's memory bandwidth and ROP count interact with the game's rendering demands.

At 4K Ultra, the combo drops to 53.8 FPS, which is below the 60 FPS threshold often considered smooth. The 4K High result of 68 FPS is playable but not high-refresh. The 4K Medium of 81.5 FPS shows that reducing settings from Ultra to Medium yields a 51.5% improvement (53.8 to 81.5), which is substantial and points to the GPU's shading and texture units being heavily taxed at Ultra. The 12 GB VRAM is ample for Doom at these settings, so capacity is not the bottleneck; rather, the 432.0 GB/s bandwidth and 192-bit bus limit the fillrate at high resolutions. The GPU's 96 ROPs are sufficient for 1080p but become a constraint at 4K, where the pixel count quadruples.

Measured FPS Breakdown

At 1920x1080, the combo delivers the following average FPS by settings: Low 262.7, Medium 230.7, High 193, Ultra 158.3. The step from Low to Medium is a 12.2% drop, from Medium to High is a 16.3% drop, and from High to Ultra is an 18.0% drop. This pattern shows a gradual increase in GPU load as settings rise, but even at Ultra, the frame rate remains above 150 FPS, indicating that the CPU is still capable of feeding the GPU adequately at this resolution.

At 2560x1440, the averages are: Low 172.1, Medium 147.1, High 127.3, Ultra 99.4. The delta between Low and Ultra is 72.7 FPS, which is a 42.2% reduction. Notably, the 1440p Medium result of 147.1 FPS is very close to the 1080p Ultra result of 158.3 FPS, suggesting that the GPU is now the primary limiter at 1440p, as the extra pixels offset the settings reduction.

At 3840x2160, the averages are: Low 94.8, Medium 81.5, High 68, Ultra 53.8. The scaling from Low to Ultra is a 43.2% reduction (94.8 to 53.8). The 4K Medium result of 81.5 FPS is 17.2% lower than the 4K Low, while the 4K High is 16.6% lower than Medium. This consistent drop of roughly 16-17% per settings tier at 4K indicates that the GPU's compute and memory subsystems are saturated, and each settings increase adds a proportional rendering cost.

The combo rank in game is 733 out of 1681 total combos, placing it in the 56th percentile of tested configurations. This rank reflects that while the CPU and GPU are both capable, the combination is not top-tier for Doom, likely due to the GPU's mid-range position. The data is measured, not estimated, which adds confidence to the interpretation.
