Doom

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4080 combination delivers exceptional performance in the 2016 classic Doom, consistently exceeding the 60 FPS playability threshold across every tested resolution and preset. The measured data shows this pairing is not merely capable but overwhelmingly dominant, with average frame rates ranging from a low of 85 FPS at 4K Ultra to a staggering 401 FPS at 1080p Low.

Measured FPS Breakdown

The benchmark data provides a comprehensive view of performance across three resolutions and four quality presets, with average frame rates (avgFps) and, where available, minimum (minFps) and maximum (maxFps) values for the Medium preset.

3840x2160 (4K):

• Low: 141 avgFps
• Medium: 123 avgFps, with a minimum of 104 and maximum of 141 FPS
• High: 104 avgFps
• Ultra: 85 avgFps

At 4K, the scaling from Low to Ultra shows a steady decline of 56 FPS, representing a 40% drop in average frame rate when moving from the least to most demanding preset. The Medium preset's min/max spread of 37 FPS (104-141) indicates some frame-time variance, but the average remains well above the 60 FPS threshold.

2560x1440 (1440p):

• Low: 260 avgFps
• Medium: 226 avgFPS, with a minimum of 192 and maximum of 260 FPS
• High: 191 avgFps
• Ultra: 156 avgFps

The 1440p results show a similar pattern, with a 104 FPS gap between Low and Ultra settings. The Medium preset demonstrates a minimum of 192 FPS, which is more than three times the playable threshold. The variance between minimum and maximum at Medium is 68 FPS, suggesting the engine scales well with the hardware.

1920x1080 (1080p):

• Low: 401 avgFps
• Medium: 350 avgFps, with a minimum of 297 and maximum of 402 FPS
• High: 295 avgFps
• Ultra: 241 avgFps

At 1080p, the combination produces triple-digit frame rates even at the most demanding preset. The Low preset's 401 FPS average approaches the theoretical ceiling for many displays, and the Medium preset's minimum of 297 FPS still exceeds the High preset's average at 1440p. The scaling from Ultra to Low yields a 160 FPS improvement, highlighting the GPU's headroom at this resolution.

Best Settings per Resolution

The data shows that this system can run Doom at the maximum Ultra preset at every resolution while maintaining frame rates far above the 60 FPS playability threshold.

3840x2160: Ultra preset runs at 85 avgFps. This is the most demanding configuration tested, yet it still provides a 25 FPS buffer over the playable threshold.

2560x1440: Ultra preset achieves 156 avgFps. The performance here is more than double the 60 FPS requirement, offering smooth gameplay with substantial headroom for frame-time spikes.

1920x1080: Ultra preset delivers 241 avgFps. This is the optimal configuration for competitive play, where high refresh rates matter more than visual fidelity.

For users prioritizing maximum visual quality, the Ultra preset is viable at all three resolutions. The data indicates no scenario where a lower preset is necessary to achieve playable performance.

Similar Performance Alternatives

The nearest rivals for the AMD Ryzen 9 9900X provide context for CPU-bound scenarios. The AMD EPYC 9015 scores 57,555 in average benchmark, a 0.1% difference from the 9900X's 57,498 average. The Intel Core i9-14900 scores 58,115, which is 1.1% higher, while the AMD EPYC 7313 scores 57,399, a 0.2% margin. The Intel Xeon Platinum 8260M scores 58,323, 1.4% above the 9900X. In practical terms, these processors would yield nearly identical frame rates in Doom, as the game's engine is unlikely to be CPU-limited at the tested settings.

For the NVIDIA GeForce RTX 4080, the closest performance match is the RTX 4080 SUPER with an average score of 54,209, just 0.1% below the RTX 4080's 54,247. The AMD Radeon Pro W5700X scores 54,828, 1.1% higher, while the AMD Radeon RX 6750 GRE 12 GB scores 55,698, a 2.6% advantage. The AMD Radeon 8060S leads this group with 55,757, 2.7% above the RTX 4080. These small deltas mean any of these GPUs would produce nearly identical frame rates in Doom, with differences well within the margin of measurement error.

The Verdict

This PC configuration runs Doom with exceptional authority at every resolution and preset combination tested. The verdict data confirms that all four presets—Low, Medium, High, and Ultra—are playable at all three resolutions.

At 3840x2160, the Ultra preset delivers 85 avgFps, providing a 25 FPS margin above the 60 FPS threshold. The High preset at 104 avgFps and Medium at 123 avgFps offer even greater headroom, while Low reaches 141 avgFps. Every option clears the playability bar by a substantial margin.

The 2560x1440 results are even more emphatic. Ultra runs at 156 avgFps, which is 96 FPS above the threshold. High achieves 191 avgFps, Medium reaches 226 avgFps, and Low hits 260 avgFps. The minimum recorded frame rate at Medium is 192 FPS, which alone exceeds the Ultra preset's average at 4K.

At 1920x1080, the system is effectively uncapped. Ultra runs at 241 avgFps, High at 295, Medium at 350, and Low at 401. The Medium preset's minimum of 297 FPS is nearly five times the playable threshold. For gamers with high-refresh-rate monitors, this configuration can push frame rates that exceed most display capabilities.

The verdict is unambiguous: this PC runs Doom at maximum settings with frame rates that exceed the playable threshold by at least 25 FPS at 4K, 96 FPS at 1440p, and 181 FPS at 1080p.

CPU and GPU Roles

The benchmark data reveals how the workload shifts between the AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4080 as resolution and settings change.

At 1920x1080, the GPU is not the bottleneck. The Low preset's 401 avgFps versus Ultra's 241 avgFps demonstrates a 160 FPS swing driven almost entirely by GPU load. The CPU's 12 cores and 24 threads, with a boost clock of 5.60 GHz, provide ample processing power to feed the GPU at these high frame rates. The single-thread performance score of 1,286 in 3DMark and 2,253 in Cinebench R23 indicates strong per-core capability, which matters for Doom's engine that does not scale perfectly across many threads.

At 2560x1440, the balance shifts toward the GPU. The scaling from Low (260 avgFps) to Ultra (156 avgFps) shows a 104 FPS reduction, which is consistent with increased pixel shading and texture work. The CPU still has headroom, as evidenced by the 226 avgFps at Medium with a 192 FPS minimum. The RTX 4080's 9728 shading units and 48.74 TFLOPS FP32 performance become the primary determinant of frame rate.

At 3840x2160, the GPU is clearly the limiting factor. The 141 avgFps at Low drops to 85 avgFPS at Ultra, a 56 FPS difference. The 4K resolution demands significantly more from the RTX 4080's 16 GB GDDR6X memory and 716.8 GB/s bandwidth. The CPU's performance becomes less relevant as the GPU takes longer to render each frame, allowing the 9900X to stay well ahead of the GPU's demands.

The pattern is clear: at 1080p, the CPU's capability to issue draw calls and manage game logic matters more, while at 4K, the GPU's raw throughput dominates. The 9900X's dual 70.6 mm² dies and 64 MB L3 cache provide sufficient bandwidth to avoid becoming a bottleneck even at 401 FPS.
