Doom

The AMD Ryzen 9 5950X paired with the AMD Radeon RX 6800 XT delivers a benchmark profile in Doom that is defined by massive headroom at lower resolutions and a predictable transition to GPU-bound performance at 4K. The dataset shows a system capable of extreme frame rates, yet the scaling pattern between 1080p and 1440p reveals where the CPU’s influence begins to wane.

Resolution Scaling

The measured FPS data shows a steep, consistent drop as resolution increases, which is the classic signature of a GPU-limited workload at higher pixel counts. At 1080p with Low settings, the combo averages 290.5 FPS. Moving to 1440p Low, the average falls to 190.2 FPS, a reduction of approximately 34.5%. The trend continues to 4K Low, where the average is 103.7 FPS, another drop of roughly 45.5% from the 1440p figure. This pattern indicates that at 1080p, the Ryzen 9 5950X’s 16 cores and 32 threads are not the bottleneck; the frame rate is so high that the GPU’s rendering throughput is the limiting factor even at the lowest settings.

The scaling from Medium to High settings at each resolution reinforces this interpretation. At 1080p, the gap between Low and High is 75.1 FPS (290.5 vs 215.4), which is a substantial difference but still leaves the system above 200 FPS. At 1440p, the same settings gap is 49.1 FPS (190.2 vs 139.1), showing that the GPU is becoming more stressed. At 4K, the gap narrows to 30.2 FPS (103.7 vs 73.5), and the absolute frame rates drop below 100 FPS for High settings. The data suggests that while the CPU provides ample single-thread performance—evidenced by a 3DMark single-thread score of 944 and a Passmark single-thread score of 3470—the transition to 4K puts the Radeon RX 6800 XT’s 16 GB of GDDR6 memory and 512.0 GB/s bandwidth under significant load.

The most telling data point is the Ultra preset scaling. At 1080p Ultra, the average is 175.3 FPS. At 1440p Ultra, it drops to 112.8 FPS, and at 4K Ultra, it falls to 64 FPS. This represents a 63.5% reduction from 1080p to 4K. The fact that 4K Ultra is the only configuration in the entire dataset that dips below 70 FPS indicates that the combination is well-matched for high-refresh 1440p gaming, but 4K Ultra pushes the GPU to its limits. The benchmark results show that the limiting component shifts decisively to the GPU as resolution climbs, with the CPU’s role diminishing from a potential co-bottleneck at 1080p to a non-factor at 4K.

GPU Role

The AMD Radeon RX 6800 XT is the primary driver of the frame rates seen in this dataset, particularly at higher resolutions. The GPU’s specifications show a boost clock of 2250 MHz and a game clock of 2015 MHz, with a base clock of 1825 MHz. These clock speeds are relevant because the benchmark results show a clear correlation between the graphics load and performance. The GPU’s 16 GB of GDDR6 memory on a 256-bit bus provides 512.0 GB/s of bandwidth, which is sufficient for the texture loads at 4K, but the data shows that Ultra settings still cause a significant performance hit.

The GPU’s compute capabilities are substantial, with 4608 shading units and a FP32 performance of 20.74 TFLOPS. This raw power is reflected in the Passmark G3D score of 24980, which places the GPU in the 87th percentile of all GPUs. However, the benchmark results in Doom show that the GPU’s performance is not uniform across settings. The difference between 4K Medium (92 FPS) and 4K High (73.5 FPS) is 18.5 FPS, while the difference between 4K High and 4K Ultra (64 FPS) is 9.5 FPS. This suggests that the Ultra preset introduces effects that are particularly taxing on the GPU’s memory subsystem or shading units.

The GPU’s role as the bottleneck at 4K is further confirmed by comparing the scaling from 1440p to 4K. At Low settings, the drop is 86.5 FPS (190.2 to 103.7), while at Ultra settings, the drop is 48.8 FPS (112.8 to 64). The smaller absolute drop at Ultra settings indicates that the GPU is already saturated, and the additional pixel count at 4K has a proportionally smaller impact. The GPU’s nearest rival, the NVIDIA GeForce RTX 4070 Ti SUPER, has an average benchmark score that is 2.6% higher, but the RX 6800 XT’s 16 GB memory capacity is a notable asset for high-resolution textures.

How This Combo Ranks

The combo’s rank of 578 out of 1681 tested configurations places it in the 65th percentile of all systems tested in Doom. This is a strong showing, but it is important to contextualize it with the individual component rankings. The CPU itself is in the 93rd percentile of all CPUs, with an average benchmark score of 49062. The GPU is in the 87th percentile of all GPUs, with an average benchmark score of 49982. The fact that the combo’s in-game rank is lower than either component’s individual percentile suggests that the pairing, while excellent, is not perfectly optimized for this specific title.

The CPU’s nearest rivals provide a useful comparison. The Intel Core i5-14600K has an average score that is 0.2% lower, while the AMD EPYC 4345P is 1.1% higher. These are marginal differences, indicating that the Ryzen 9 5950X is competitively positioned. For the GPU, the nearest rival data shows the NVIDIA CMP 50HX is 1.9% lower and the RTX 4070 Ti SUPER is 2.6% higher. The combination of a top-tier CPU and a high-end GPU results in a system that is capable of high frame rates, but the rank of 578 suggests that there are many configurations with faster GPUs or more balanced pairings that achieve higher scores in Doom.

The rank also reflects the game’s release date of 2016-05-12. Doom’s engine is known for being well-optimized, and the data shows that even a 2020-era CPU and GPU can produce frame rates above 200 FPS at 1080p. The combo’s rank is not a reflection of poor performance; rather, it is a measure of how many other systems in the database can achieve even higher frame rates in this specific title. Given that the 4K Ultra result of 64 FPS is the only sub-70 FPS measurement, the combo is clearly capable of handling this game at high settings on most displays.

Measured FPS Breakdown

The dataset provides a complete matrix of average FPS across three resolutions and four settings levels, with no min or max FPS values recorded. At 1920x1080, the results are as follows: Low settings yield 290.5 FPS, Medium yields 253.6 FPS, High yields 215.4 FPS, and Ultra yields 175.3 FPS. The spread from Low to Ultra is 115.2 FPS, which is the largest absolute spread of any resolution. This indicates that at 1080p, the system has enough headroom that even the most demanding settings still produce frame rates well above 170 FPS.

At 2560x1440, the average FPS values are 190.2 for Low, 162 for Medium, 139.1 for High, and 112.8 for Ultra. The spread from Low to Ultra is 77.4 FPS, which is smaller than at 1080p. This reduction in spread is expected as the GPU becomes more utilized. The 1440p results show that the system is still capable of exceeding 100 FPS on all settings, making it an excellent choice for 1440p high-refresh-rate gaming.

At 3840x2160, the results show the most significant drop. Low settings produce 103.7 FPS, Medium produces 92 FPS, High produces 73.5 FPS, and Ultra produces 64 FPS. The spread from Low to Ultra is 39.7 FPS, which is the smallest spread of any resolution. This narrow gap indicates that the GPU is the limiting factor across all settings at 4K, as the performance is constrained by the rendering workload rather than the CPU. The 4K results also show that the system can maintain playable frame rates up to High settings, but Ultra settings dip to 64 FPS, which is just above the 60 FPS baseline.

The data also shows a consistent pattern of diminishing returns as settings increase. At 1080p, the jump from Low to Medium is a 36.9 FPS increase, while the jump from High to Ultra is a 40.1 FPS decrease. At 4K, the jump from Low to Medium is an 11.7 FPS decrease, and the jump from High to Ultra is a 9.5 FPS decrease. This pattern suggests that the performance cost of each settings tier is relatively consistent, but the absolute impact is smaller at higher resolutions because the GPU is already working near its capacity.
