Doom

The AMD Ryzen 7 7800X3D paired with the NVIDIA GeForce RTX 5080 delivers exceptionally high frame rates in Doom, establishing this combination as a top-tier performer for the 2016 title. The data shows a system that is overwhelmingly GPU-bound at higher resolutions, with the CPU’s architecture providing a robust foundation that prevents bottlenecks even at 1080p. This analysis breaks down the measured performance across resolutions, component roles, and settings to determine the optimal configuration for this hardware pairing.

Resolution Scaling

The measured frame rates reveal a clear and predictable scaling pattern as resolution increases, though the magnitude of the drop is significant. At 1080p with High settings, the combo produces 315.3 FPS, which serves as the baseline for this analysis. Moving to 1440p, the average frame rate falls to 204.2 FPS, representing a 35.2% reduction from the 1080p figure. The jump to 4K further compounds this, with the High preset delivering 110.1 FPS, a 65.1% drop from the 1080p result. This steep decline indicates that the rendering workload scales dramatically with pixel count, which is expected for a game from this era that lacks modern upscaling technologies.

The scaling pattern across all four presets reinforces the GPU-bound nature of this configuration. For the Low preset, the system achieves 397.1 FPS at 1080p, 275.5 FPS at 1440p, and 146.5 FPS at 4K. The relative performance retention from 1080p to 4K is 36.9% for Low settings, compared to 34.9% for High settings. This consistency across presets suggests that the limiting component is the GPU’s rasterization throughput, not the CPU or memory subsystem. The RTX 5080’s 960.0 GB/s memory bandwidth and 56.28 TFLOPS FP32 compute are the primary drivers of these results, and the data indicates that even at 4K, the GPU is still delivering playable frame rates.

Interestingly, the gap between 1080p and 1440p is smaller in absolute terms than the gap between 1440p and 4K. For High settings, the 1080p to 1440p drop is 111.1 FPS, while the 1440p to 4K drop is 94.1 FPS. This suggests that the GPU’s pixel throughput scales sub-linearly with resolution, likely due to the fixed overhead of geometry processing and draw calls. The 4K results, ranging from 88.2 FPS on Ultra to 146.5 FPS on Low, indicate that the RTX 5080 is capable of maintaining high refresh rates at this resolution, though the Ultra preset dips below the 90 FPS threshold that many high-refresh displays target.

CPU Role

The AMD Ryzen 7 7800X3D provides the computational backbone for this system, and its specifications align well with the demands of Doom. The processor features 8 cores and 16 threads based on the Zen 4 architecture, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. The 96 MB of shared L3 cache is a notable asset for gaming workloads, as it reduces memory latency and improves data locality for frequently accessed game assets. The CPU’s benchmark scores corroborate its strength: a Cinebench R23 multi-core score of 29149 and a single-core score of 4115 indicate balanced performance that excels in both threaded and lightly-threaded scenarios.

In the context of Doom, the CPU’s role is primarily to feed the GPU with draw calls and game logic updates. The measured frame rates at 1080p Low, which reach 397.1 FPS, suggest that the 7800X3D is not a limiting factor at lower resolutions where GPU load is lighter. The CPU’s 3DMark scores further contextualize its capability: a 16-thread score of 7980 and a single-thread score of 959 demonstrate strong per-core performance that is essential for games that rely on a main game thread. The processor’s percentile ranking of 87 among all CPUs places it in the upper tier, and its nearest rivals—the Intel Core i7-12700F (0.1% ahead) and AMD Ryzen 9 5980HX (0.3% ahead)—show that the 7800X3D is competitive with, but not dramatically superior to, other high-end desktop parts.

The data indicates that the CPU’s contribution to frame rates is largely indirect, enabling the GPU to operate at full utilization. At 4K Ultra, where the GPU is heavily loaded, the CPU still manages to deliver 88.2 FPS, which is above the 60 FPS threshold that most players consider acceptable. The 7800X3D’s 120 W TDP and 5 nm process node from TSMC suggest efficient power delivery, but the benchmark results are what matter: the processor’s ability to maintain high instruction throughput without becoming a bottleneck is evident from the consistent scaling across resolutions.

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this system, and its specifications directly explain the measured performance. The GPU features 10752 shading units, 336 texture mapping units, and 112 render output units, operating at a boost clock of 2617 MHz. The 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is crucial for feeding the high pixel throughput required at 4K resolution. The GPU’s FP32 compute of 56.28 TFLOPS and texture rate of 879.3 GTexel/s are substantial, and the benchmark results reflect this capability: a Passmark G3D score of 36565 and a 3DMark Steel Nomad DX12 score of 8637.

The GPU’s percentile ranking of 89 among all GPUs places it in the upper echelon, though its nearest rivals in the database are notably lower-tier parts. The Intel Arc A570M is 1.6% behind, the Intel Arc Pro A60 is 1.9% ahead, and the Intel Arc A580 is 2.5% behind. This clustering is unusual; it suggests that the benchmark database’s scoring methodology may weight certain workloads differently than the measured FPS in Doom. The RTX 5080’s raw specifications, such as its 293.1 GPixel/s pixel rate, are more indicative of its real-world gaming performance than these aggregate scores.

In Doom, the GPU’s role is paramount. The frame rate differences between presets at the same resolution highlight the GPU’s sensitivity to rendering quality. At 4K, the Ultra preset produces 88.2 FPS, while the Low preset reaches 146.5 FPS—a 66.0% increase. This differential is consistent with the GPU being the primary bottleneck, as reducing settings lowers the pixel shading workload and allows the GPU to process frames faster. The RTX 5080’s 84 RT cores and 336 tensor cores are largely irrelevant for this 2016 title, which predates widespread ray tracing adoption, but the raw rasterization throughput is what drives these results. The GPU’s 360 W TDP and suggested 750 W PSU indicate a high-power component, and the data confirms that this power is translated into exceptional frame rates across all tested configurations.

Settings Recommendations

The measured data provides a clear hierarchy for optimizing the experience on this hardware. At 1080p, all presets exceed 257 FPS, making the choice purely about visual fidelity versus headroom. The Ultra preset’s 257.1 FPS is more than sufficient for any display refresh rate, so players should prioritize image quality at this resolution. The 1080p High preset at 315.3 FPS offers a balance, but Ultra’s visual improvements justify the 58.2 FPS reduction.

At 1440p, the High preset at 204.2 FPS emerges as the recommended configuration. This frame rate comfortably exceeds 144 Hz displays and provides 39.4 FPS more than Ultra’s 164.8 FPS. The Medium preset at 238.2 FPS offers additional headroom for competitive play, but High’s visual quality upgrade over Medium is worth the 34 FPS cost. Ultra at 1440p remains playable at 164.8 FPS, but the margin over High is marginal for the performance hit.

At 4K, the recommendation shifts to Medium settings, which deliver 127.7 FPS. This provides a 17.6 FPS advantage over High (110.1 FPS) and a 39.5 FPS advantage over Ultra (88.2 FPS). The 4K Medium preset is the best choice for high-refresh displays, as it stays above 120 FPS while maintaining acceptable visual quality. The Low preset at 146.5 FPS is viable for esports-focused players, but the visual degradation is significant. Ultra at 4K, while producing 88.2 FPS, should only be used for slower-paced gameplay where frame rates above 60 FPS are sufficient. Across all resolutions, the data consistently shows that the High and Medium presets offer the best balance of visual fidelity and performance, with Ultra reserved for players who prioritize image quality over frame rate.
