Doom

The AMD Ryzen 7 5700 and NVIDIA GeForce RTX 5080 combination delivers exceptional performance in Doom, but the data reveals a fascinating shift in system dynamics as resolution increases. This pairing is clearly capable of producing extremely high frame rates, yet the bottleneck analysis changes dramatically depending on whether you are gaming at 1080p or 4K. The measured FPS data provides a clear picture of where each component's strengths lie and how they interact under different graphical loads.

Resolution Scaling

The most striking observation in the data is the dramatic FPS progression as resolution decreases. At 4K Ultra, the combo averages 91.5 FPS, which jumps to 166.1 FPS at 1440p Ultra, and further climbs to 256.2 FPS at 1080p Ultra. This scaling pattern reveals the GPU's dominance as the primary limiting factor at higher resolutions. The RTX 5080's workload increases substantially with pixel count, and the 4K results show a significant performance cost relative to lower resolutions.

When examining the Low settings across resolutions, the picture becomes even clearer. At 1080p Low, the system achieves 348.1 FPS, but this only rises to 277.9 FPS at 1440p Low and 149.5 FPS at 4K Low. The gap between 1080p and 1440p at Low settings is relatively modest (about 25%), while the jump from 1440p to 4K is much more severe (roughly 46% drop). This suggests that at 1080p, the CPU is beginning to exert more influence on performance, as the GPU has ample headroom to render frames quickly.

The data implies that this system is balanced for high-refresh-rate 1440p gaming, where it can push past 240 FPS on Medium settings. At 4K, the GPU becomes the clear bottleneck, with performance scaling closely tied to graphics complexity rather than resolution alone. The FPS drops from 1080p to 4K are not linear, indicating that the RTX 5080's memory bandwidth and compute capabilities are being stretched at higher pixel densities.

CPU Role

The AMD Ryzen 7 5700 brings 8 cores and 16 threads to the table, running at a base clock of 3.70 GHz and boosting to 4.60 GHz. This Zen 3 architecture processor, built on a 7 nm process, demonstrates strong multi-threaded capabilities in synthetic benchmarks, with a Cinebench R23 multicore score of 20655 and a single-core score of 2916. The CPU's 16 MB of L3 cache and dual-channel DDR4 memory support at 51.2 GB/s provide a solid foundation for gaming workloads.

In the context of Doom, the CPU's role becomes more apparent at lower resolutions. The 1080p Low setting yields 348.1 FPS, which is only about 12% higher than the 1080p High result of 309.3 FPS. This relatively small difference suggests that the CPU is capable of feeding the GPU with enough frames, but the rendering pipeline is not entirely CPU-bound even at these high frame rates. The processor's 3DMark single-thread score of 901 and multi-thread score of 6617 indicate balanced performance that can handle the game's physics and logic threads without becoming a severe constraint.

Compared to its nearest rivals, the Ryzen 7 5700 holds its own. It edges out the Intel Core i9-9900K by 0.7% in average benchmark score, and leads the Intel Core i7-12700H by 0.8%. This competitive positioning suggests the CPU is not a weak link in this combo, even when paired with a high-end GPU like the RTX 5080. However, the data cannot definitively isolate the CPU's contribution to gaming performance, as the measured FPS reflects the entire system's capabilities.

GPU Role

The NVIDIA GeForce RTX 5080 is the clear performance driver in this system, featuring 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth. Its Blackwell 2.0 architecture includes 10752 shading units, 336 texture mapping units, and 112 raster output units, with boost clocks reaching 2617 MHz. The GPU's compute capabilities are substantial, with FP32 performance rated at 56.28 TFLOPS.

The GPU's impact on Doom performance is most evident in the Ultra settings scaling. At 1080p Ultra, the system achieves 256.2 FPS, but this drops to 166.1 FPS at 1440p Ultra and 91.5 FPS at 4K Ultra. This represents a 64% reduction in frame rate from 1080p to 4K, highlighting the GPU's workload intensification at higher resolutions. The RTX 5080's 16 GB VRAM capacity is more than sufficient for Doom at any setting, but the compute demands of 4K rendering push the GPU to its limits.

The GPU's percentile ranking of 89 versus all GPUs indicates it is a high-end part, though its nearest rivals in the benchmark database show some interesting comparisons. The Intel Arc A580 trails by 2.5%, while the AMD Radeon Pro W5500X is 2.6% behind, suggesting the RTX 5080's performance is well above average. However, the Intel Arc Pro A60 actually leads by 1.9%, which is notable given the RTX 5080's positioning as a flagship product.

Measured FPS Breakdown

At 1920x1080, the system's performance is exceptional across all settings. Low settings produce 348.1 FPS, Medium reaches 328.6 FPS, High achieves 309.3 FPS, and Ultra still delivers 256.2 FPS. The consistency of these numbers suggests the CPU can maintain high frame delivery, with the GPU handling the rendering efficiently. The gap between Low and Ultra is only about 26%, indicating that even at maximum settings, the system has substantial headroom.

Moving to 2560x1440, the performance remains strong but shows more variation. Low settings yield 277.9 FPS, Medium reaches 240.2 FPS, High achieves 205 FPS, and Ultra drops to 166.1 FPS. The scaling here is more pronounced, with Ultra being 40% slower than Low. This suggests the GPU is becoming more of a limiting factor, though the frame rates remain highly playable for competitive gaming.

At 3840x2160, the GPU workload becomes dominant. Low settings still produce a respectable 149.5 FPS, Medium hits 129 FPS, High manages 111.8 FPS, and Ultra falls to 91.5 FPS. The difference between Low and Ultra at 4K is about 39%, showing that graphical complexity has a significant impact at this resolution. The 4K results indicate that while the system can handle 4K gaming, the frame rates are more modest compared to lower resolutions.

How This Combo Ranks

This specific combination of AMD Ryzen 7 5700 and NVIDIA GeForce RTX 5080 ranks 84th out of 1681 tested combos for Doom, placing it in the top 5% of all configurations. This ranking reflects the system's ability to deliver high frame rates across all resolutions and settings. The percentile positioning suggests that this pairing is well-matched for the game, with neither component severely bottlenecking the other in most scenarios.

The rank of 84 out of 1681 indicates that while this is a strong performer, there are 83 other combinations that achieve better results in Doom. This could be due to more powerful CPUs or GPUs in other systems, or more balanced pairings. However, the data shows that this combo significantly outperforms the vast majority of tested configurations, making it a viable choice for high-refresh-rate gaming.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's target resolution and refresh rate. For 1080p gaming, even Ultra settings provide 256.2 FPS, which is sufficient for any high-refresh-rate monitor. The performance difference between High and Ultra at 1080p is only 17%, so users with 144Hz or 240Hz displays can comfortably select Ultra for maximum visual quality.

At 1440p, the choice becomes more nuanced. High settings deliver 205 FPS, which is excellent for competitive play, while Ultra drops to 166.1 FPS. For users with 144Hz monitors, either setting works well, but High offers a 23% performance boost over Ultra with only a modest visual compromise. Those with 240Hz displays would need to use Medium settings (240.2 FPS) to fully utilize their monitor's capabilities.

For 4K gaming, the settings have a more pronounced impact on playability. Medium settings provide 129 FPS, which is smooth for most players, while High drops to 111.8 FPS and Ultra to 91.5 FPS. The data suggests that High settings offer the best balance for 4K, providing a substantial visual upgrade over Medium while maintaining frame rates above 100 FPS. Low settings at 4K (149.5 FPS) are only recommended for users prioritizing maximum frame rates over visual fidelity.
