Doom

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 4080 delivers an exceptionally strong Doom experience, with the data showing that frame rates remain remarkably high even at maximum settings and 4K resolution. This combination ranks 215th out of 3712 tested combos, placing it in the top 6% of all configurations evaluated for this title. The benchmark results reveal a system that is heavily GPU-bound at higher resolutions, while the processor’s capabilities become more apparent at lower settings and resolutions.

Resolution Scaling

The measured FPS data shows a clear and consistent pattern of performance degradation as resolution increases, which is typical for a game like Doom that relies heavily on the graphics card for rendering. At 1080p with Low settings, the combination produces an average of 401 FPS. Moving to 1440p Low drops this to 260 FPS, a reduction of 141 FPS or roughly 35%. At 4K Low, the average falls further to 141 FPS, which is a 65% decrease from the 1080p figure. This scaling pattern indicates that the GPU is the primary limiting component across all tested configurations, as the frame rate drop is roughly proportional to the increase in pixel count.

The scaling behavior becomes even more pronounced when examining the High settings preset. At 1080p High, the system achieves 295 FPS, which drops to 191 FPS at 1440p High—a 104 FPS reduction. At 4K High, the average falls to 104 FPS, representing a 64.7% decrease from the 1080p High result. This consistent scaling pattern across different settings presets strongly suggests that the RTX 4080’s rendering throughput is the bottleneck, rather than the CPU. If the processor were the limiting factor, we would expect to see a smaller performance gap between 1080p and 1440p, as the CPU workload remains relatively constant while the GPU workload increases with resolution.

The data also reveals that the transition from Medium to Ultra settings has a more substantial impact on frame rates than resolution changes alone. At 4K, the difference between Low (141 FPS) and Ultra (85 FPS) is 56 FPS, while the difference between 1440p and 4K at Medium settings is 103 FPS (226 FPS to 123 FPS). This indicates that both resolution and settings complexity contribute significantly to the overall performance envelope, with the GPU’s compute and memory subsystems being taxed heavily by both factors.

Settings Recommendations

Based on the measured FPS rows, the optimal balance between visual fidelity and frame rate appears to be the High preset at 1440p, which delivers an average of 191 FPS. This configuration provides a substantial performance cushion above the 144 FPS threshold commonly associated with high-refresh-rate gaming, while still offering significantly better visual quality than the Low preset. The Medium preset at 1440p, which achieves 226 FPS, represents a more performance-oriented choice for competitive play, but the visual quality difference between Medium and High is typically noticeable in Doom’s detailed environments.

For users prioritizing maximum frame rates, the Low preset at 1080p delivers 401 FPS, which is well beyond what most displays can even show. However, this comes at a significant visual cost. The Medium preset at 1080p, at 350 FPS, offers a more reasonable compromise for esports-style play, providing nearly the same performance headroom while improving visual fidelity. At 4K, the High preset at 104 FPS is the recommended starting point, as it maintains smooth gameplay while offering the higher resolution experience. The Ultra preset at 4K drops to 85 FPS, which is still playable but may not be ideal for fast-paced action sequences in Doom.

The data shows that the High preset at 1440p is the sweet spot for this combination, as it delivers 191 FPS while presumably offering most of the visual features that make the game look modern. The 1440p Medium preset at 226 FPS is the best choice for those who prioritize frame rate over visual detail, and the 4K High preset at 104 FPS is the best option for 4K display owners who want a balance of resolution and performance. The Ultra preset, while visually superior, only appears in the data at 241 FPS for 1080p and 156 FPS for 1440p, suggesting that it is best reserved for lower resolutions where the performance cost is less impactful.

GPU Role

The NVIDIA GeForce RTX 4080 plays the dominant role in determining Doom’s performance across all tested configurations. The GPU’s 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is more than sufficient for Doom’s texture and geometry demands at 4K resolution. The memory clock runs at 1400 MHz, or 22.4 Gbps effective, and the GPU’s base clock of 2205 MHz with a boost clock of 2505 MHz allows it to sustain high utilization during intense rendering scenes.

The RTX 4080’s Ada Lovelace architecture, built on a 5 nm process at TSMC, contains 45,900 million transistors across a 379 mm² die. The GPU’s 9728 shading units, 304 texture mapping units, and 112 render output units contribute to its 48.74 TFLOPS of FP32 performanceches. This raw compute power is what drives the high frame rates observed in the data, particularly at 1440p and 1080p where the GPU is not as heavily constrained by pixel throughput requirements.

The GPU’s average benchmark score of 54247 places it in the 86th percentile of all GPUs, and its nearest rival, the NVIDIA GeForce RTX 4080 SUPER, scores 54209, a mere 0.1% difference. This indicates that the RTX 4080 is operating at the top of its class for Doom, with the measured FPS data confirming that it is capable of producing frame rates that far exceed what most displays can show at 1080p and 1440p. The GPU’s 320 W TDP and triple-slot design suggest that adequate cooling is necessary to maintain boost clocks, but the benchmark results show no signs of thermal throttling affecting performance.

Measured FPS Breakdown

At 1920x1080, the combination produces exceptional frame rates across all settings. The Low preset delivers 401 FPS average, which is the highest measured value in the entire dataset. Medium settings achieve 350 FPS with a minimum of 297 FPS and a maximum of 402 FPS, showing tight frame pacing. High settings drop to 295 FPS, while Ultra settings still maintain 241 FPS. These numbers indicate that at 1080p, the system is almost certainly CPU-limited at Low settings, as the GPU has ample headroom to render frames faster than the processor can submit them.

At 2560x1440, the performance remains very high but shows the GPU beginning to take a more significant role. Low settings produce 260 FPS, Medium settings yield 226 FPS with a minimum of 192 FPS and maximum of 260 FPS, High settings reach 191 FPS, and Ultra settings drop to 156 FPS. The scaling from 1080p to 1440p at Medium settings shows a 35.4% reduction in frame rate, which is less than the pixel count increase of 77.8%, suggesting that the GPU still has spare capacity but is increasingly constrained by rendering workload.

At 3840x2160, the GPU is clearly the limiting factor. Low settings achieve 141 FPS, Medium settings yield 123 FPS with a minimum of 104 FPS and maximum of 141 FPS, High settings drop to 104 FPS, and Ultra settings fall to 85 FPS. The difference between Low and Ultra at 4K is 56 FPS, which is a 39.7% reduction. This shows that even at 4K, the RTX 4080 has enough performance to run the game at playable frame rates, but the Ultra preset pushes the GPU to its limits with 85 FPS average.

CPU Role

The AMD Ryzen 9 9900X3D’s role in Doom’s performance is primarily to ensure that the GPU is never starved of data, which is evident from the measured FPS data. The CPU’s 12 cores and 24 threads, based on the Zen 5 architecture (Granite Ridge), provide substantial processing capability. Its base clock of 4.40 GHz and boost clock of 5.50 GHz, combined with a 128 MB L3 cache, allow it to handle game logic and frame submission efficiently. The CPU’s dual-channel DDR5 memory support with 89.6 GB/s bandwidth ensures that data can flow quickly to the GPU, although Doom’s memory footprint is not particularly demanding.

The CPU’s benchmark scores show strong multi-threaded performance, with a Cinebench R23 multicore score of 47737 and a Geekbench multicore score of 22884. Its single-thread performance is also robust, with a Geekbench single-core score of 3041 and a Cinebench R23 single-core score of 6739. These scores indicate that the CPU can handle both the serial and parallel workloads present in Doom’s engine. The fact that the FPS scaling from 1080p to 1440p at Low settings shows only a 35.2% reduction (from 401 FPS to 260 FPS) suggests that the CPU is capable of providing frames at a rate higher than the GPU can render at 1080p Low.

The CPU’s nearest rivals in terms of average benchmark score include the Intel Core Ultra 5 245KF, which is 0.6% slower, and the Intel Core Ultra 5 245K, which is 1.3% slower. The AMD processor’s 91st percentile ranking indicates that it is among the top processors available, and its 120 W TDP is modest for the performance it delivers. The CPU’s 4 nm process node and 16,630 million transistors on a 2x 70.6 mm² die show that it is a modern, efficient design that pairs well with the RTX 4080 to achieve the high frame rates observed in Doom.
