Doom

The AMD Ryzen 9 9950X3D and NVIDIA GeForce RTX 5090 combination delivers exceptional performance in Doom, with measured frame rates that place this pairing at the top of the database. The data shows a system capable of extreme refresh rates at any resolution, but the scaling patterns reveal a nuanced story about where the bottleneck shifts between the CPU and GPU.

Resolution Scaling

The measured FPS data shows a clear progression as resolution increases, with the most dramatic drop occurring between 1080p and 1440p. At 1080p with Low settings, the combo achieves 462.3 FPS, but this falls to 300 FPS at 1440p — a substantial reduction of 162.3 FPS. The scaling continues to 4K, where Low settings produce 162.1 FPS, representing a 300.2 FPS drop from the 1080p result.

This scaling pattern indicates that at 1080p, the system is heavily CPU-limited. The Ryzen 9 9950X3D's 16 cores and 32 threads, combined with its 5.70 GHz boost clock, are pushing frame rates well beyond what most displays can show, but the GPU still has headroom. The 462.3 FPS at 1080p Low reflects the CPU's ability to feed the RTX 5090 at lower resolutions.

Moving to 1440p, the frame rates remain exceptionally high — 300 FPS at Low settings — but the drop from 1080p indicates the GPU is beginning to take on more of the workload. At 4K, the scaling becomes more pronounced, with the gap between 1080p and 4K at Low settings reaching 300.2 FPS. The 4K results, ranging from 98.5 FPS at Ultra to 162.1 FPS at Low, suggest the RTX 5090 is now the primary limiting factor, though it still delivers playable-to-excellent performance at the highest resolution.

The most telling comparison is between 1440p and 4K at High settings: 221.4 FPS versus 121.1 FPS. This 100.3 FPS difference represents a 45.3% reduction, clearly showing the increased pixel workload at 4K. The system transitions from a CPU-bound configuration at 1080p to a GPU-bound one at 4K, with 1440p serving as the crossover point where both components are heavily utilized.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant force in this pairing, particularly at higher resolutions. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is critical for 4K gaming. The GPU's 21760 shading units and 176 ROPs deliver the raw compute needed to maintain high frame rates at demanding resolutions.

The clock behavior is notable: the base clock of 2017 MHz boosts to 2407 MHz, and the memory runs at 1750 MHz with 28 Gbps effective speed. This combination of high core clocks and fast memory allows the RTX 5090 to maintain 121.1 FPS at 4K High settings and 98.5 FPS at 4K Ultra. The Ultra preset's 98.5 FPS result shows that even at maximum settings, the GPU keeps the experience smooth, though it falls below the 100 FPS threshold that many enthusiasts prefer.

At 1440p, the GPU's capabilities are more apparent. The 300 FPS at Low settings and 257.9 FPS at Medium show the RTX 5090 can handle high refresh rate 1440p gaming with ease. The 181.4 FPS at 1440p Ultra is particularly impressive, indicating that players can max out settings while still enjoying frame rates well above 144 Hz.

The GPU's benchmark scores reinforce its position. The 3DMark Steel Nomad DX12 score of 14411 and PassMark G3D score of 39650 place it in the 94th percentile of all GPUs. Its average benchmark score of 84306 is nearly identical to the RTX 5090 D, which sits just 0.1% ahead, and it leads the AMD Radeon PRO W6600 by 1.3%. The RTX 5090's performance in Doom aligns with its synthetic benchmark standing — it's a top-tier GPU that only faces competition from its closest variants.

CPU Role

The AMD Ryzen 9 9950X3D provides the foundation for this system's exceptional performance, particularly at lower resolutions. With 16 cores and 32 threads based on Zen 5 architecture, the CPU's 128 MB of shared L3 cache is substantial, and its boost clock of 5.70 GHz ensures single-threaded workloads are handled efficiently.

The CPU's impact is most visible at 1080p, where it enables frame rates like 462.3 FPS at Low settings and 340 FPS at High. These numbers exceed what most gaming monitors can display, confirming that the CPU is not a bottleneck at this resolution. Even at 4K, the CPU's role remains important; the 162.1 FPS at Low settings suggests the CPU can still push frames faster than the GPU can render them at this resolution.

Synthetic benchmarks show the CPU's strength. The Cinebench R23 multicore score of 59712 and single-core score of 8430 demonstrate excellent multi-threaded and single-threaded performance. The Geekbench multicore score of 22515 and single-core score of 3401 reinforce this picture. The 3DMark results are particularly relevant: the 16-thread score of 16374 and max-thread score of 17184 show strong scaling across cores, which benefits games that can utilize multiple threads.

The CPU's 96th percentile ranking among all CPUs is supported by its average benchmark score of 71660. It sits just 0.9% behind the Intel Xeon Platinum 8270 and 1.8% ahead of the AMD Ryzen 9 9950X. The 9950X3D's edge over the standard 9950X is likely attributable to the additional cache, which can benefit gaming workloads.

How This Combo Ranks

This pairing of the Ryzen 9 9950X3D and RTX 5090 achieves the top spot in the database for Doom, ranking 1st out of 1681 tested combinations. This is the definitive performance configuration for this game according to measured results.

The rank reflects the synergy between the two components. The CPU's ability to maintain high frame rates at 1080p and 1440p complements the GPU's strength at 4K, creating a system with no significant weak points. The 462.3 FPS at 1080p Low and 300 FPS at 1440p Low are among the highest recorded results in the database, while the 4K Ultra result of 98.5 FPS remains competitive.

The gap between this combo and the rest of the field is substantial. No other tested configuration in the 1681-combo pool outperforms this pairing, which is expected given the CPU's 96th percentile and GPU's 94th percentile rankings. The combination of the fastest consumer CPU and fastest consumer GPU produces the best possible Doom experience.

Settings Recommendations

The measured data provides clear guidance for optimal settings at each resolution. At 1080p, the High preset delivers 340 FPS, which is more than sufficient for any display. The Ultra preset at 279.4 FPS is also viable, though the 60.6 FPS difference between High and Ultra may not justify the visual upgrade for competitive players.

At 1440p, the High preset at 221.4 FPS is the sweet spot. It offers a 40 FPS advantage over Ultra's 181.4 FPS while still providing excellent visual quality. The Medium preset at 257.9 FPS is the choice for those prioritizing maximum refresh rates, though the difference between Medium and High is less pronounced than between High and Ultra.

At 4K, the High preset at 121.1 FPS is the recommended choice. It maintains a comfortable margin above 100 FPS while providing better visuals than Medium's 142.6 FPS. The Ultra preset at 98.5 FPS is playable but dips below 100 FPS, so High offers the best balance of performance and quality. The Low preset at 162.1 FPS is unnecessary at this resolution, as High already provides smooth gameplay.
