However, in this specific game, the RTX 4080’s measured performance shows it is more than sufficient to drive high frame rates.

GPU Role

The NVIDIA GeForce RTX 4080 is the workhorse for frame generation in Doom. With 16 GB of GDDR6X memory on a 256-bit bus, it offers 716.8 GB/s of memory bandwidth. The GPU’s base clock is 2205 MHz, boosting to 2505 MHz, and its memory runs at 1400 MHz (22.4 Gbps effective). These specs allow it to handle the game’s texture and geometry loads without breaking a sweat.

The measured FPS data shows the GPU scaling almost linearly with settings at 1080p. At Low settings, it averages 401 FPS, which drops to 350 FPS at Medium, 295 FPS at High, and 241 FPS at Ultra. This pattern indicates that the GPU is not the limiting factor at 1080p; the CPU is capable of feeding it frames faster than it can render them, but the headroom is still substantial.

At 1440p, the GPU takes on more responsibility. The average FPS at Low is 260, dropping to 226 at Medium, 191 at High, and 156 at Ultra. The gap between Low and Ultra is 104 FPS, showing that the game is becoming more GPU-bound as resolution increases. At 4K, this trend continues: 141 FPS at Low, 123 FPS at Medium, 104 FPS at High, and 85 FPS at Ultra. The RTX 4080’s 16 GB VRAM is more than adequate for this game, even at 4K Ultra, as no VRAM-related stutters are indicated in the data.

The GPU’s compute capabilities are strong, with 9728 shading units and 48.74 TFLOPS of FP32 performance. This translates directly into the high pixel rates observed, with the GPU achieving a pixel rate of 280.6 GPixel/s. For a game like Doom, which relies on fast, fluid action, this GPU ensures that even the most intense scenes remain smooth.

Resolution Scaling

The data shows a clear progression as resolution increases, with the RTX 4080 becoming the primary bottleneck at higher settings. From 1080p to 1440p, the average FPS at High settings drops from 295 to 191, a 35% reduction. From 1440p to 4K, it drops further to 104, another 45% reduction. This scaling is typical for a GPU-bound scenario, where the number of pixels rendered quadruples from 1080p to 4K.

At Low settings, the scaling is even more dramatic: 401 FPS at 1080p, 260 FPS at 1440p, and 141 FPS at 4K. The 1080p to 1440p drop is 35%, while the 1440p to 4K drop is 46%. This indicates that even at Low settings, the GPU is being pushed harder at higher resolutions, but the CPU still has enough headroom to avoid being a limiting factor.

The game’s minimum FPS data also supports this. At 1080p Medium, the minimum is 297 FPS, while the maximum is 402 FPS. At 1440p Medium, the minimum is 192 FPS, and at 4K Medium, the minimum is 104 FPS. These figures show that the frame time consistency is excellent, with no severe dips that would indicate a CPU bottleneck. The limiting component at 4K Ultra is clearly the GPU, as the average FPS of 85 is still high but shows the most significant drop from the 1080p Ultra score of 241 FPS.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor based on the Zen 5 architecture (Granite Ridge), built on a 4 nm process. Its base clock is 4.30 GHz, boosting up to 5.70 GHz. The CPU’s standout feature is its 128 MB of L3 cache, which is critical for gaming performance. This large cache allows the CPU to store more game data locally, reducing the need to access slower system memory (DDR5) and improving frame consistency.

In synthetic benchmarks, the 9950X3D excels. Its Cinebench R23 multicore score is 42,018, and its single-core score is 2,259. These numbers are indicative of a processor that can handle both heavily threaded workloads and the single-threaded tasks that games often depend on. The 3DMark scores show a similar pattern: 17,184 in the max-thread test and 1,292 in the single-thread test.

The CPU’s role in Doom is to feed the GPU with draw calls and game logic. At 1080p Low, the system achieves 401 FPS, which is near the upper limit of what most displays can show. The fact that the FPS drops to 241 at 1080p Ultra while the CPU remains the same suggests that the CPU is not the limiting factor; the GPU is. The CPU’s high single-thread performance (PassMark single-thread score of 4,737) ensures that it can keep up with the GPU’s frame output.

Compared to its nearest rivals, the 9950X3D is only 0.1% to 0.4% faster in average benchmark scores. This means that for Doom, the choice between this CPU and the Ryzen 7 PRO 9755 or Intel Core Ultra 9 285 would result in nearly identical frame rates. The CPU’s 128 MB L3 cache is a unique advantage, but the game’s engine appears to be more GPU-limited at higher resolutions.

Settings Recommendations

At 1440p, the High preset delivers 191 FPS, which is excellent for high-refresh-rate monitors up to 165 Hz. The Ultra preset at 156 FPS is also a solid option if you prefer maximum visual quality and have a 144 Hz display. For competitive play, the Low preset at 260 FPS offers the highest frame rates, though it sacrifices visual detail.

At 1080p, the High preset at 295 FPS is more than sufficient for any monitor, and the Ultra preset at 241 FPS still provides a very high refresh rate. The data shows that Medium at 1080p (350 FPS) is a sweet spot for those seeking the highest possible frame rates without the visual degradation of Low settings. The minimum FPS at 1080p Medium is 297, ensuring that even the most intense scenes remain above 290 FPS.

In summary, the best experience per the measured rows is achieved with the Medium preset at 4K (123 FPS) or the High preset at 1440p (191 FPS). These settings provide a strong balance between visual quality and frame rate, ensuring a responsive and immersive experience in Doom. The Ultra preset is only recommended for those with lower refresh rate displays, as the performance cost is substantial across all resolutions.
