Doom

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 5080 delivers exceptional performance in Doom, placing this combination at rank 47 out of 1681 tested configurations. The data shows a system capable of extreme frame rates, even at 4K, though the scaling patterns reveal distinct bottlenecks depending on resolution and settings.

Resolution Scaling

The frame rate progression from 1080p to 4K demonstrates classic GPU-bound behavior, but with a twist unique to this title's optimization. At 1080p with Low settings, the system produces 426.2 FPS, which drops to 274.9 FPS at 1440p and further to 152.2 FPS at 4K. This represents a 64% reduction from 1080p to 4K at Low settings, indicating the GPU is the primary limiter even at lower resolutions. The RTX 5080's 56.28 TFLOPS of FP32 compute and 960.0 GB/s memory bandwidth are being taxed heavily by Doom's Vulkan renderer.

Moving to High settings, the scaling becomes steeper. The 1080p result of 315.3 FPS falls to 203.2 FPS at 1440p (a 36% drop) and then to 111 FPS at 4K (a further 45% drop). The total 4K penalty versus 1080p sits at 65%, which is nearly identical to the Low preset's 64% penalty. This consistency suggests that resolution scaling is largely independent of quality preset, a hallmark of a well-optimized engine where pixel count dominates the workload.

Ultra settings tell a different story. The 1080p score of 257 FPS drops to 167.5 FPS at 1440p (35% reduction) and then to 89.8 FPS at 4K (46% reduction). The 4K Ultra result is the only one in the entire dataset that dips below 100 FPS, suggesting that at this extreme quality level, the combination of pixel throughput and shader complexity begins to overwhelm the GPU's 112 ROPs and 336 TMUs. The relative consistency of percentage drops across presets (64-66% from 1080p to 4K) indicates the RTX 5080 maintains its efficiency curve regardless of settings, with no sudden cliff or unexpected collapse.

GPU Role

The RTX 5080's specifications are central to interpreting these results. With 16 GB of GDDR7 memory on a 256-bit bus delivering 960.0 GB/s, the card has ample bandwidth for Doom's texture-heavy environments at any resolution. The 10752 shading units and 84 RT cores provide substantial compute headroom, though Doom's 2016 engine primarily relies on traditional rasterization rather than ray tracing.

The clock behavior is notable: base clock of 2295 MHz with a boost of 2617 MHz. The measured FPS suggests the GPU sustains high clocks under load, as even the most demanding 4K Ultra scenario produces 89.8 FPS, which would require consistent boost operation. The pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are directly relevant — at 4K Ultra, the system needs to fill 8.3 million pixels per frame, and the 89.8 FPS result implies the GPU is processing roughly 745 million pixels per second, which is well within its theoretical pixel rate.

The GPU's benchmark scores corroborate its strength. The 3DMark Steel Nomad DX12 score of 8637 and Passmark G3D score of 36565 place it at the 89th percentile of all GPUs. Its nearest rivals in the database are notably different products — the Intel Arc A570M (1.6% lower), Arc Pro A60 (1.9% higher), Arc A580 (2.5% lower), and AMD Radeon Pro W5500X (2.6% lower) — but these comparisons reflect synthetic averages rather than Doom-specific performance. The data shows the RTX 5080 decisively outperforms these rivals in this game based on the measured FPS.

FAQ

Q: Can this system maintain 60 FPS at 4K Ultra in Doom?

A: Yes, with significant headroom. The measured 4K Ultra average is 89.8 FPS, which is 50% above the 60 FPS target.

Q: What is the fastest preset at 1080p?

A: Low settings produce the highest frame rate at 426.2 FPS, followed by Medium at 373.2 FPS, High at 315.3 FPS, and Ultra at 257 FPS.

Q: How does the RTX 5080 compare to its nearest GPU rival in this game?

A: The RTX 5080's average benchmark score of 59188 is 1.6% higher than the Intel Arc A570M's 58239, but this is a synthetic comparison. In Doom specifically, the measured FPS at 4K High (111 FPS) demonstrates real-world capability that far exceeds what the deltaPct suggests.

Q: Is the CPU or GPU the bottleneck at 1440p High?

A: The data suggests GPU limitation. The 1440p High result of 203.2 FPS is 36% lower than 1080p High, indicating that resolution-dependent GPU work dominates. The CPU's 12 cores and 24 threads are sufficient to feed the GPU at these rates.

Q: What is the performance difference between Low and Ultra at 4K?

A: Low produces 152.2 FPS while Ultra produces 89.8 FPS, a gap of 62.4 FPS or roughly 41% lower performance at Ultra. This is the largest relative gap between presets at any resolution.

Q: Does the system ever exceed 400 FPS?

A: Yes, but only at 1080p with Low settings, where it reaches 426.2 FPS. No other resolution or settings combination exceeds 400 FPS.

Measured FPS Breakdown

At 1920x1080, the system demonstrates remarkable throughput. Low settings yield 426.2 FPS, which drops to 373.2 FPS at Medium (12% reduction), 315.3 FPS at High (26% reduction), and 257 FPS at Ultra (40% reduction). The step from Low to Medium is the smallest penalty at 53 FPS, while the jump from High to Ultra costs 58.3 FPS.

The 2560x1440 results show a similar pattern but with lower absolute values. Low produces 274.9 FPS, Medium reaches 239.2 FPS (13% lower), High hits 203.2 FPS (26% lower), and Ultra manages 167.5 FPS (39% lower). The consistency of these percentage deltas across resolutions — approximately 12-13% for Medium, 26% for High, and 39-40% for Ultra — suggests the engine scales quality settings uniformly regardless of pixel count.

At 3840x2160, the absolute numbers compress further. Low delivers 152.2 FPS, Medium drops to 130.8 FPS (14% lower), High reaches 111 FPS (27% lower), and Ultra falls to 89.8 FPS (41% lower). The 4K Low result of 152.2 FPS is still exceptionally high for a 4K resolution, indicating the RTX 5080's raw pixel throughput is substantial. The progression from 1080p Low to 4K Low represents a 64% reduction, while the same progression at Ultra represents a 65% reduction, showing that resolution has a near-constant multiplicative effect on frame rate.

CPU Role

The AMD Ryzen 9 7900X brings substantial compute resources to this pairing. Its 12 cores and 24 threads operate at a base clock of 4.70 GHz with a boost up to 5.60 GHz, providing the kind of single-thread performance that Doom's engine favors. The Cinebench R23 single-core score of 6168 and multi-core score of 43695 indicate strong per-thread capability, which is critical for a game engine that typically uses fewer threads but demands high IPC.

The CPU's benchmark profile shows it sits at the 93rd percentile of all CPUs, with an average benchmark score of 50556. Its nearest rivals are remarkably close: the Intel Core Ultra 5 235 is just 0.1% higher, the AMD Ryzen 9 5900XT is 0.4% lower, the Intel Core i7-13850HX is 0.5% lower, and the Intel Core i9-13980HX is 0.8% lower. This grouping suggests the 7900X is at a performance plateau where minor architectural differences matter little.

In Doom specifically, the CPU's role becomes evident at lower resolutions. The 1080p Low result of 426.2 FPS represents a frame every 2.35 milliseconds, which challenges even the fastest CPUs to feed the GPU. The 7900X's 24 threads and high boost clock of 5.60 GHz are likely the reason the system can sustain these rates without stalling. The L3 cache of 64 MB shared across 12 cores helps maintain data locality for the game's level geometry and entity state.

Settings Recommendations

For players targeting maximum frame rates, Low settings at 1080p provide the highest measured performance at 426.2 FPS, though this is likely beyond the refresh rate of most displays. The jump to Medium costs only 53 FPS at 1080p (12% reduction) while presumably offering better visual quality, making it a logical choice for competitive play where 373.2 FPS still exceeds virtually any monitor's capability.

At 1440p, the data shows High settings at 203.2 FPS as the sweet spot for high-refresh displays. This is comfortably above 144 Hz and even exceeds 200 Hz thresholds. Ultra at 167.5 FPS remains viable for 144 Hz panels, but the 35.7 FPS penalty versus High suggests diminishing returns unless visual fidelity is paramount.

For 4K gaming, High settings at 111 FPS provide the best balance of quality and performance, staying above 100 FPS. Ultra at 89.8 FPS is playable on 90 Hz displays but falls short of 120 Hz targets. Medium at 130.8 FPS offers a strong alternative for those with 120 Hz 4K panels, while Low at 152.2 FPS is the only 4K preset that clears 144 Hz. The data indicates that High is the recommended default for 4K, with Medium as a fallback for higher refresh rates and Ultra reserved for those prioritizing image quality over frame rate.
