Doom

The AMD Ryzen 9 5950X paired with the AMD Radeon RX 6650 XT delivers a robust performance profile in Doom, with the data indicating a system that scales predictably across resolutions. At 1080p, the combo achieves an average of 200.6 FPS on Low settings, but this drops to 117.6 FPS on Ultra, a difference of 83 FPS. This spread demonstrates that the GPU is the primary limiting factor even at the lowest resolution, as the CPU’s high thread count and boost clock are more than sufficient to feed the graphics card. Moving to 1440p, the frame rates compress slightly: Low settings yield 126.8 FPS, while Ultra falls to 76.9 FPS. The gap between Low and Ultra narrows from 83 FPS at 1080p to 49.9 FPS at 1440p, suggesting that the rendering load is shifting more heavily onto the GPU. At 4K, the trend intensifies, with Low settings producing 70.7 FPS and Ultra dropping to 39.8 FPS. The delta between Low and Ultra at 4K is 30.9 FPS, which is proportionally smaller than at lower resolutions, indicating that the GPU is now fully saturated and the CPU has ample headroom. This scaling pattern is classic for a mid-range GPU paired with a high-end CPU: the 5950X’s 16 cores and 32 threads are never the bottleneck, and the RX 6650 XT’s 8 GB of GDDR6 memory becomes the decisive factor as pixel count rises.

How This Combo Ranks

In the broader database of tested combinations, this pairing holds a combo rank of 1109 out of 1681 combos for Doom. This places it in the upper third of all tested systems, which is a strong showing given that the RX 6650 XT is a mid-range card. The CPU component, the Ryzen 9 5950X, ranks in the 93rd percentile against all CPUs, with an average benchmark score of 49062. Its nearest rival, the Intel Core i5-14600K, scores 49166, a delta of -0.2%, meaning the 5950X is essentially tied with that chip in overall CPU performance. The Ryzen 9 also holds a slight edge over the Intel Xeon Gold 5318H, which scores 48698, a delta of 0.7% in favor of the AMD part. On the GPU side, the RX 6650 XT sits in the 72nd percentile against all GPUs, with an average score of 29024. Its nearest rival, the AMD Radeon RX 6800M, scores 29011, a delta of 0%, indicating near-identical raw compute performance. The fact that this combo ranks 1109 out of 1681 is notable because the CPU is far more capable than the GPU, meaning the overall ranking is dragged down by the graphics card’s mid-tier status. In Doom specifically, which is a well-optimized title, the 5950X’s single-thread performance—evidenced by its Geekbench single-core score of 2211 and Cinebench R23 single-core score of 5450—ensures that frame pacing remains consistent, even when the GPU is pushed to its limits at 4K.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with the Navi 23 chip, featuring 2048 shading units, 128 texture mapping units, and 64 render output units. Its memory subsystem consists of 8 GB of GDDR6 on a 128-bit bus, providing a bandwidth of 280.3 GB/s. The card’s base clock is 2055 MHz, with a game clock of 2410 MHz and a boost clock of 2635 MHz. These clocks are relatively high for the segment, and they directly influence the measured frame rates. In Doom, the GPU’s performance at 1080p High (148 FPS) is strong, but the drop to 117.6 FPS at Ultra shows that the 8 GB VRAM capacity is being stressed by higher texture quality settings. The card’s pixel rate of 168.6 GPixel/s and texture rate of 337.3 GTexel/s are sufficient for 1080p and 1440p gaming, but at 4K, the fill rate becomes a limiting factor. The data shows that at 4K Ultra, the average FPS falls to 39.8, which is below the 60 FPS threshold for smooth gameplay. This is not a CPU limitation, as the 5950X’s 64 MB of L3 cache and 32 threads are more than enough; it is purely the GPU’s compute and memory bandwidth being overwhelmed. The RX 6650 XT’s FP32 performance of 10.79 TFLOPS is respectable, but it pales in comparison to what is needed for consistent 4K Ultra in a fast-paced FPS. The card’s 32 ray accelerators do not meaningfully impact Doom, which is a rasterization-heavy title, so the measured results are a pure reflection of the GPU’s raw rasterization throughput.

Settings Recommendations

Based on the measured FPS data, the optimal balance between visual fidelity and frame rate is achieved at the High preset across most resolutions. At 1080p, High yields 148 FPS, which is comfortably above the 144 Hz refresh rate common on modern monitors, while Ultra drops to 117.6 FPS, still playable but sacrificing some headroom. For 1440p, High delivers 95.6 FPS, which is ideal for a 100 Hz display, whereas Medium produces 114.4 FPS, offering a slight competitive advantage at the cost of some visual detail. The Ultra preset at 1440p falls to 76.9 FPS, which is still smooth but not optimal for high-refresh-rate play. At 4K, the situation changes dramatically. High settings produce 51.6 FPS, which is borderline playable, but Medium is a better choice at 63.1 FPS, providing a more stable experience without a significant visual downgrade. The Low preset at 4K achieves 70.7 FPS, which is a viable option for players who prioritize frame rate over visuals, but the jump from Low to Medium is only 7.6 FPS, making Medium the smarter choice for 4K. The Ultra preset at 4K is not recommended, as the 39.8 FPS average is below the 40 FPS threshold for acceptable playability in a fast-paced shooter. Overall, the data suggests that High is the sweet spot for 1080p and 1440p, while Medium is the best compromise for 4K, given that it maintains a playable frame rate while preserving most of the visual enhancements.

Measured FPS Breakdown

The measured FPS data provides a clear picture of how the combo performs at each resolution and settings tier. At 3840x2160, the averages are as follows: Low yields 70.7 FPS, Medium produces 63.1 FPS, High drops to 51.6 FPS, and Ultra falls to 39.8 FPS. The progression from Low to Ultra shows a steady decline of 8.2 FPS from Low to Medium, 11.5 FPS from Medium to High, and 11.8 FPS from High to Ultra. This consistent drop indicates that each settings tier adds a similar amount of GPU load, with the largest single step being between High and Ultra. At 2560x1440, the averages are 126.8 FPS for Low, 114.4 FPS for Medium, 95.6 FPS for High, and 76.9 FPS for Ultra. The deltas here are 12.4 FPS from Low to Medium, 18.8 FPS from Medium to High, and 18.7 FPS from High to Ultra, showing that the step from Medium to High is the most demanding. At 1920x1080, the averages are 200.6 FPS for Low, 171.8 FPS for Medium, 148 FPS for High, and 117.6 FPS for Ultra. The deltas are 28.8 FPS from Low to Medium, 23.8 FPS from Medium to High, and 30.4 FPS from High to Ultra. Interestingly, the largest absolute drop at 1080p is between High and Ultra, which is the same pattern seen at 4K. This suggests that the Ultra preset in Doom includes a specific effect or texture setting that disproportionately impacts the RX 6650 XT, regardless of resolution. The 1080p Low result of 200.6 FPS is particularly noteworthy, as it demonstrates that the CPU is capable of pushing well over 200 FPS in this title, and the GPU is the sole factor preventing higher numbers at lower settings. Overall, the data shows a system that is well-balanced for 1080p and 1440p gaming, with 4K being a stretch that requires dropping to Medium settings for a playable experience.
