Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 7 5700X and NVIDIA GeForce RTX 5080 shows a clear and predictable resolution scaling pattern. Moving from 1920x1080 to 2560x1440 at High settings, the average frame rate drops from 310.4 FPS to 202.2 FPS, a reduction of roughly 35%. The subsequent step to 3840x2160 at High settings yields 108.2 FPS, which is approximately 46% lower than the 1440p result. This steepening decline as resolution increases is a classic indicator that the rendering load is shifting progressively onto the GPU.

At the Low preset, the scaling behavior is even more pronounced. The 1080p result of 356.4 FPS falls to 278.2 FPS at 1440p, and then drops sharply to 148.7 FPS at 4K. The gap between 1440p and 4K at Low settings is a 46.5% reduction, which is larger than the corresponding drop at High settings. This suggests that at lower graphical loads, the CPU becomes a more significant factor at 1080p and 1440p, allowing the GPU to stretch its legs; but at 4K, the GPU's raw pixel-pushing capability becomes the dominant constraint regardless of preset.

The Ultra preset shows the most dramatic scaling. From 253.9 FPS at 1080p, the frame rate drops to 166.8 FPS at 1440p (a 34.3% decrease) and then to 89.2 FPS at 4K (a 46.5% decrease from 1440p). The 4K Ultra result is the lowest measured value in the entire dataset, confirming that this combination of components is pushed to its limits at the highest resolution and quality settings. The data indicates that the RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are sufficient to handle 4K textures without catastrophic frame drops, but the sheer computational load of Ultra settings at 4K still exacts a heavy toll.

CPU Role

The AMD Ryzen 7 5700X provides the computational foundation for this combo. With 8 cores and 16 threads based on the Zen 3 architecture, the processor operates at a base clock of 3.40 GHz and a boost clock of 4.60 GHz. Its 32 MB of shared L3 cache and 4,150 million transistors on a 7 nm TSMC process node position it as a capable mid-range desktop part. The data shows that in Doom, a game originally released in 2016, the CPU's role is primarily to feed the GPU with draw calls and game logic.

The CPU's benchmark results reveal its multi-threaded capability. The Cinebench R23 multicore score of 22620 and the 3DMark max threads score of 6850 indicate strong parallel performance. However, the single-thread scores are more telling for this genre: the 3DMark single-thread score of 921 and Cinebench R23 single-core score of 3193 suggest that the processor can handle the primary game thread without becoming a bottleneck at most settings. The PassMark physics score of 1337 further corroborates this, as physics calculations often rely on single-thread performance.

At 1080p with Low settings, the combo achieves 356.4 FPS, which is remarkably close to the theoretical ceiling imposed by the CPU. The fact that the 1080p Low result is only 46.2% higher than the 4K Low result, despite the 4K resolution requiring four times the pixel throughput, indicates that the CPU is not the limiting factor at lower resolutions. Instead, the data suggests that the Ryzen 7 5700X has sufficient headroom to drive the RTX 5080 even at high frame rates. The CPU's percentile ranking of 83 against all processors, with an average benchmark score of 26214, places it within striking distance of rivals like the Intel Core i9-11900KF (deltaPct 0.1%) and the AMD Ryzen 5 7600X (deltaPct -0.2%).

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing. Built on the Blackwell 2.0 architecture with the GB203 chip, the GPU features 10,752 shading units, 336 texture mapping units, and 112 raster output units. Its 84 RT cores and 336 tensor cores provide dedicated hardware for ray tracing and AI workloads, though Doom's traditional rasterization path primarily exercises the shading units and ROPs. The GPU's boost clock of 2617 MHz and base clock of 2295 MHz drive its 56.28 TFLOPS of FP32 compute.

The memory subsystem is particularly relevant for Doom at high resolutions. The 16 GB of GDDR7 memory on a 256-bit bus delivers 960.0 GB/s of bandwidth, which prevents memory bandwidth from becoming a constraint even at 4K Ultra settings. The pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are the specifications that directly influence fill-rate-bound scenarios, and the measured FPS data reflects this capability. The GPU's 3DMark Steel Nomad DX12 score of 8637 and PassMark G3D score of 36565 place it in the 89th percentile of all GPUs, with an average benchmark score of 59188.

The scaling from 1080p to 4K at each preset reveals the GPU's performance envelope. At High settings, the frame rate drops from 310.4 to 108.2 FPS, a 65.1% reduction that is proportional to the 4x increase in pixel count. This near-linear scaling indicates that the RTX 5080 is the primary bottleneck at 4K, with the CPU contributing minimal overhead. The GPU's nearest rivals, including the Intel Arc A570M (deltaPct 1.6%) and Intel Arc Pro A60 (deltaPct -1.9%), are significantly weaker in absolute terms, reinforcing the RTX 5080's position as a high-end part.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across resolutions and settings. At 1920x1080, the combo delivers 356.4 FPS on Low, 338.1 FPS on Medium, 310.4 FPS on High, and 253.9 FPS on Ultra. The progression from Low to Ultra at 1080p costs 28.8% of the frame rate, which is a modest penalty given the visual quality improvements. The 1080p results all exceed 250 FPS, making this resolution entirely GPU-bound at the highest refresh rates available.

At 2560x1440, the frame rates remain high but begin to show the GPU's workload. Low settings produce 278.2 FPS, Medium yields 242.2 FPS, High drops to 202.2 FPS, and Ultra settles at 166.8 FPS. The gap between Low and Ultra at 1440p is 40.0%, which is wider than at 1080p, indicating that the GPU's computational resources are becoming more strained. The 1440p High result of 202.2 FPS still exceeds the refresh rate of most high-end monitors, suggesting that this combo can drive 1440p at maximum visual fidelity without compromise.

At 3840x2160, the performance landscape changes dramatically. Low settings produce 148.7 FPS, Medium drops to 128.5 FPS, High yields 108.2 FPS, and Ultra falls to 89.2 FPS. The 4K results are the only ones that dip below 100 FPS, with Ultra being the sole preset that fails to maintain triple-digit frame rates. The spread from Low to Ultra at 4K is 40.0%, identical to the 1440p spread, which suggests that the GPU's resource allocation scales consistently across these resolutions.

How This Combo Ranks

The combination of the AMD Ryzen 7 5700X and NVIDIA GeForce RTX 5080 achieves a combo rank of 83 out of 1,681 tested combinations in Doom. This places the pairing in the top 4.9% of all combos, indicating exceptional performance for this title. The rank reflects the synergy between the CPU's 8-core/16-thread configuration and the GPU's massive compute resources. The data confirms that this is a high-end pairing capable of delivering excellent frame rates across all tested resolutions.

The CPU's nearest rivals provide context for its contribution to this rank. The AMD Ryzen 7 PRO 6850U and AMD Ryzen 5 7600X both have deltaPct values of -0.2% relative to the 5700X, meaning they are statistically indistinguishable in average benchmark score. Similarly, the Intel Core i9-11900KF (deltaPct 0.1%) and AMD Ryzen 5 5500GT (deltaPct 0.2%) are within a fraction of a percent. This suggests that the CPU's performance level is well-matched to the GPU, with no single component creating a disproportionate bottleneck.

The GPU's ranking further supports this analysis. With a percentile of 89 against all GPUs and an average benchmark score of 59188, the RTX 5080 is a top-tier part. Its nearest rivals in the database — the Intel Arc A570M, Intel Arc Pro A60, Intel Arc A580, and AMD Radeon Pro W5500X — all have lower average scores, with deltas ranging from 1.6% to 2.6%. This gap underscores the RTX 5080's position as a high-end GPU that pairs effectively with the Ryzen 7 5700X.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. At 1920x1080, the Ultra preset delivers 253.9 FPS, which is sufficient for even the fastest 240 Hz monitors. The drop from Ultra to High at 1080p only costs 56.5 FPS, but the visual quality difference may justify the performance hit for competitive play. For maximum visual fidelity at 1080p, Ultra is the clear choice, as the frame rate remains well above any practical refresh rate ceiling.

At 2560x1440, the High preset offers the best balance, delivering 202.2 FPS while maintaining high visual quality. The Ultra preset at 1440p still achieves 166.8 FPS, which is playable on 144 Hz displays, but the 35.4 FPS penalty over High may not be worth the marginal visual improvement. For gamers with 240 Hz 1440p monitors, the Medium preset at 242.2 FPS is the recommended choice, as it provides a substantial frame rate boost over High while still looking superior to Low.

At 3840x2160, the Medium preset at 128.5 FPS is the sweet spot for 120 Hz displays, offering a 20.3 FPS improvement over High while maintaining respectable visual quality. The High preset at 108.2 FPS is viable for 100 Hz monitors but leaves little headroom. The Ultra preset at 89.2 FPS is only suitable for 60 Hz displays, where it provides a comfortable margin above the refresh rate. The Low preset at 148.7 FPS is recommended for competitive 4K gaming on 144 Hz panels, as it maximizes frame rate while sacrificing visual fidelity. The data shows that this combo is most effective when the settings are tailored to the display's refresh rate, with Medium at 4K providing the best overall experience for most users.
