Doom

This combo pairs the AMD Ryzen 7 5800X with the NVIDIA GeForce RTX 5090 D for Doom, and the resulting performance data shows a system that is overwhelmingly GPU-bound at higher resolutions. The benchmark results indicate that while the CPU is a capable partner, the RTX 5090 D's massive memory bandwidth and compute resources are the primary drivers of the high frame rates observed.

How This Combo Ranks

The data places this specific CPU-GPU combination at rank 62 out of 2930 tested combos for Doom. That places it in the top 2.1% of all configurations tested, which is an exceptional result for a game released in 2016. The ranking reflects the sheer brute force of the RTX 5090 D, which can overwhelm even the most demanding titles, though the Ryzen 7 5800X ensures the system does not become a bottleneck at lower resolutions.

Looking at the CPU's individual standing, it holds the 81st percentile among all CPUs, with an average benchmark score of 29123. Its nearest rivals include the Intel Core Ultra 5 135H (avg score 29093, delta 0.1%) and the AMD Ryzen 5 5600XT (avg score 28940, delta 0.6%), showing the 5800X sits in a crowded mid-to-high-end field. For the GPU, the RTX 5090 D is in the 92nd percentile of all GPUs, with an average benchmark score of 77712. Its nearest rivals in the database are notably weaker: the AMD Radeon RX 6650M XT (avg score 76904, delta 1.1%) and the NVIDIA Tesla P100 PCIe 16 GB (avg score 79605, delta -2.4%). This suggests the 5090 D is a tier above typical gaming hardware, which is consistent with the high combo rank.

The deltaPct values show the 5800X is virtually tied with its closest competitors, meaning CPU choice between these models would not materially change Doom's frame rates. The GPU, however, has a wider gap to its rivals, reinforcing that the 5090 D is the star of this pairing. In practical terms, this combo rank is not about the CPU carrying the load; it is about the GPU being so powerful that even a mid-generation CPU like the 5800X can ride along to a top-100 finish.

GPU Role

The RTX 5090 D is a foundational component for this game's performance. It features 32 GB of GDDR7 memory on a 512-bit bus, yielding a memory bandwidth of 1.79 TB/s. This is critical for Doom, which is a fast-paced FPS that benefits from rapid texture streaming and high-resolution assets. The memory clock runs at 1750 MHz, effectively 28 Gbps, and the GPU's base clock is 2017 MHz with a boost clock of 2407 MHz.

These specifications translate directly to the measured results. At 4K Ultra, the combo still manages 102 FPS, which is only possible with the 5090 D's raw shading power (21760 shading units) and a pixel rate of 423.6 GPixel/s. The GPU's FP32 performance of 104.8 TFLOPS ensures that even the most chaotic scenes with numerous demons and particle effects do not cause the frame rate to collapse. The 32 GB VRAM is overkill for Doom, but it means the game's textures are always fully resident in memory, eliminating any potential stutter from VRAM swapping.

Comparing to its nearest rivals, the 5090 D's average benchmark score is 1.1% higher than the RX 6650M XT and 2.4% higher than the Tesla P100 16 GB. In a game like Doom, that margin translates to a tangible FPS advantage, especially at 4K where the GPU's memory subsystem is heavily taxed. The GPU's 680 TMUs and 176 ROPs also contribute to the high texture fill rates, which are essential for maintaining the 125 FPS average seen at 4K High. The data shows that the GPU is not just adequate for this game; it is overprovisioned, which is why the combo ranks so highly.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and refresh rate. At 1920x1080, the Ultra preset delivers 292 FPS, which is already well above any standard 144Hz or 240Hz monitor's capability. The Low preset only increases this to 361 FPS, so there is little reason to drop below Ultra at this resolution. The Medium preset sits at 344 FPS, and High at 324 FPS, but the visual fidelity loss from Ultra is not worth the marginal FPS gain when you are already pushing past 300 FPS.

At 2560x1440, the Ultra preset yields 189 FPS, which is still excellent for high-refresh-rate gaming. The High preset provides 231 FPS, a 22% increase over Ultra, which could benefit a 240Hz monitor. The Medium preset offers 273 FPS, and Low jumps to 312 FPS. For a competitive player with a 240Hz panel, the High preset at 1440p is the sweet spot: it offers a 42 FPS improvement over Ultra while maintaining most of the visual quality. The Low preset is not necessary unless you are chasing the absolute maximum frame rate, as the difference between High and Low is only 81 FPS.

At 3840x2160, the Ultra preset drops to 102 FPS, which is still playable on a 120Hz TV but not ideal for competitive play. The High preset raises this to 125 FPS, a 23 FPS improvement, making it the recommended choice for 4K gaming. The Medium preset provides 148 FPS, and Low reaches 170 FPS. For 4K, the High preset offers the best balance: it stays above 120 FPS, which is the target for most high-end displays, while retaining better shadows and texture filtering than Medium or Low. The data suggests that Ultra is only worth it if you have a VRR display and can tolerate the lower frame rate for maximum fidelity.

Measured FPS Breakdown

The measured FPS data provides a clear picture of how this combo scales across resolutions and settings. At 1920x1080, the frame rates are exceptionally high, starting at 361 FPS on Low and dropping to 292 FPS on Ultra. The Medium preset shows a minimum of 293 FPS and a maximum of 396 FPS, with an average of 344 FPS, indicating that the system is heavily CPU-limited at this resolution. The High preset averages 324 FPS, which is a 37 FPS drop from Low, showing that even at 1080p, the GPU is still rendering every frame with ease.

Moving to 2560x1440, the frame rates remain high but begin to show the GPU's influence. The Low preset averages 312 FPS, which is only 49 FPS lower than the 1080p Low result. The Medium preset averages 273 FPS, with a minimum of 232 FPS and a maximum of 314 FPS, showing a wider variance as the GPU starts to work harder. The High preset averages 231 FPS, and the Ultra preset drops to 189 FPS. The delta between 1080p and 1440p for the Ultra preset is 103 FPS, which is a significant drop, but the absolute number is still very playable.

At 3840x2160, the GPU becomes the clear limiting factor. The Low preset averages 170 FPS, which is a 191 FPS drop from the 1080p Low result. The Medium preset averages 148 FPS, with a minimum of 126 FPS and a maximum of 170 FPS. The High preset averages 125 FPS, and the Ultra preset falls to 102 FPS. The resolution scaling is steep: from 1080p Ultra to 4K Ultra, the frame rate drops by 190 FPS, a 65% reduction. This confirms that the CPU is more than capable of handling the game's logic, but the GPU is being pushed to its limits at 4K, even with 32 GB of VRAM.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals the bottleneck. At 1080p Low, the combo achieves 361 FPS. At 1440p Low, it drops to 312 FPS, a 13.6% reduction. At 4K Low, it falls to 170 FPS, a 52.9% reduction from the 1080p figure. This pattern is consistent across all settings, but the magnitude increases with higher quality presets. For the Ultra preset, the drop from 1080p (292 FPS) to 1440p (189 FPS) is 35.3%, and then to 4K (102 FPS) is an additional 46.0% drop from the 1440p number.

This scaling pattern indicates that the system is CPU-bound at 1080p and progressively becomes GPU-bound as resolution increases. At 1080p, the CPU's 8 cores and 16 threads are likely saturating the game's main thread, limiting the FPS to around 361. The GPU is simply waiting for instructions. At 4K, however, the GPU's rendering workload dominates, and the CPU has ample headroom to feed the 5090 D. The fact that the 4K Low preset (170 FPS) is still higher than the 1080p Ultra preset (292 FPS) shows that the GPU can deliver more frames if the CPU is not the limiting factor, but the resolution increase overwhelms the GPU's advantage.

The measured data shows that the RTX 5090 D is not fully utilized until 4K. The memory bandwidth of 1.79 TB/s is ample for 1080p and 1440p, but at 4K, the GPU's compute units are working at a higher utilization rate. The 32 GB VRAM is never a constraint, as Doom's textures are relatively small by modern standards. The limiting component at 4K is the GPU's shading throughput, which is why the FPS drops to 102 at Ultra. This suggests that for a 240Hz 1080p monitor, the CPU is the bottleneck, but for a 144Hz 4K display, the GPU is the limiting factor, and the combo is well-balanced for the latter.

FAQ
