# Doom — AMD Ryzen 5 7600 + NVIDIA GeForce RTX 4080

The measured frame rates for this combination of an AMD Ryzen 5 7600 and NVIDIA GeForce RTX 4080 in Doom show a clear and consistent pattern: performance scales dramatically with resolution and settings, but the relationship is not linear. The data indicates that this pairing is capable of high frame rates at lower resolutions, but drops sharply as the rendering load increases, suggesting that the GPU becomes the primary constraint at higher quality presets and higher pixel counts.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals how the system's workload shifts as resolution increases. At the Low preset, moving from 1920x1080 to 2560x1440 reduces the average frame rate by 37%, from 181 FPS to 114 FPS. Continuing to 3840x2160 at Low yields 60 FPS, which is another 47% reduction from the 1440p figure. This steep drop-off at 4K even on Low settings indicates that the RTX 4080's rendering capabilities are being heavily taxed by the sheer pixel count, while the CPU has ample headroom at these lower settings.

At the Medium preset, the same resolution progression shows 113 FPS at 1080p, 71 FPS at 1440p, and 37 FPS at 4K. The percentage drops are 37% and 48% respectively, mirroring the Low preset's scaling almost exactly. This consistency suggests that the limiting factor is resolution-driven rather than settings-driven — the GPU is the bottleneck across all tested configurations. The High preset follows a similar pattern: 76 FPS at 1080p, 48 FPS at 1440p (a 37% drop), and 25 FPS at 4K (a 48% drop from 1440p). The uniformity of these percentage reductions across presets is a strong indicator that the RTX 4080's fill rate and memory bandwidth are the determining factors.

The Ultra preset shows the most dramatic degradation: 47 FPS at 1080p, 30 FPS at 1440p, and just 16 FPS at 4K. The drop from 1080p to 1440p is 36%, and from 1440p to 4K is 47%, again matching the pattern. However, the absolute numbers are low even at 1080p, suggesting that the Ultra preset imposes a rendering cost that severely limits this GPU's ability to maintain playable frame rates at any resolution. The data clearly shows that 4K Ultra is the worst-case scenario, with the system delivering only 16 FPS — a figure that would be considered unplayable for a fast-paced FPS.

Settings Recommendations

Based on the measured rows, the best experience for this combination depends heavily on the target resolution. At 1920x1080, the Low preset delivers 181 FPS, which is ideal for competitive play where high refresh rates matter more than visual fidelity. The Medium preset at 113 FPS still provides a very smooth experience and likely offers noticeably better visuals than Low, making it a strong choice for most players. The High preset at 76 FPS remains fluid and would be suitable for those who prioritize image quality, while the Ultra preset at 47 FPS is the only option that dips below the 60 FPS threshold at this resolution.

At 2560x1440, the Low preset's 114 FPS is excellent, and Medium at 71 FPS remains above the 60 FPS baseline, making it a solid recommendation for a balance of quality and performance. High at 48 FPS is playable but noticeably less smooth, and Ultra at 30 FPS falls below acceptable levels for a game like Doom. For 4K, the situation is more constrained: Low at 60 FPS is the only preset that reaches the 60 FPS mark, Medium at 37 FPS is stutter-prone, and both High (25 FPS) and Ultra (16 FPS) are well outside the range of comfortable play.

The data suggests a clear hierarchy: for 1080p, Medium or High provides the best experience; for 1440p, Medium is the sweet spot; and for 4K, only Low is viable. The measured minimum frame rates for Medium at 1080p (96 FPS), 1440p (61 FPS), and 4K (32 FPS) show that even the worst-case dips remain relatively stable relative to the averages, but the 4K Medium minimum of 32 FPS would still be noticeable during intense combat sequences.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this pairing, and its specifications explain the observed scaling behavior. The GPU features 16 GB of GDDR6X memory on a 256-bit bus, yielding 716.8 GB/s of bandwidth — a figure that is sufficient for the textures and geometry in Doom at most settings, but the 4K Ultra results suggest that raw memory bandwidth is not the sole constraint. The RTX 4080's boost clock of 2505 MHz and its 9728 shading units deliver a theoretical FP32 performance of 48.74 TFLOPS, yet the measured frame rates at 4K High (25 FPS) and Ultra (16 FPS) indicate that the GPU is being pushed to its limits.

The benchmark data for the GPU shows a PassMark G3D score of 34457 and an average benchmark score of 54247, placing it in the 86th percentile among all GPUs. Its nearest rival, the NVIDIA GeForce RTX 4080 SUPER, scores 54209 with a delta of 0.1%, meaning the two are effectively identical in synthetic tests. However, the AMD Radeon RX 6750 GRE 12 GB scores 55698, a delta of -2.6%, and the AMD Radeon 8060S scores 55757, a delta of -2.7% — both slightly ahead in these benchmarks, though the RTX 4080's performance in Doom may differ due to game-specific optimizations.

The GPU's 320 W TDP and triple-slot cooler design indicate that it is designed for high sustained loads, which aligns with the demanding 4K scenarios. The memory clock of 1400 MHz with 22.4 Gbps effective speed supports the bandwidth figure, but the sharp frame rate drops at higher presets suggest that the GPU's compute units, not the memory subsystem, are the primary bottleneck. The RTX 4080's 76 RT cores and 304 tensor cores are not directly relevant to Doom's rendering path, but their presence adds to the overall die complexity (45,900 million transistors on a 379 mm² die).

CPU Role

The AMD Ryzen 5 7600 is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael, with a base clock of 3.80 GHz and a boost clock of 5.10 GHz. Its 32 MB of shared L3 cache and 1 MB L2 per core provide adequate data locality for game workloads, and its 78th percentile ranking among all CPUs reflects solid overall performance. In synthetic benchmarks, the CPU achieves a Cinebench R23 multicore score of 12735 and a single-core score of 1852, while Geekbench reports 13413 multicore and 2521 single-core.

The CPU's nearest rivals in average benchmark score include the AMD Ryzen 9 6900HX (26274, delta 0.2%), AMD Ryzen 7 7435HS (26402, delta -0.3%), Intel Core i9-11900KF (26212, delta 0.4%), and AMD Ryzen 5 8540U (26187, delta 0.5%). These deltas are all within 0.5%, indicating that the Ryzen 5 7600 performs on par with these parts in general benchmarks, though its gaming-specific behavior in Doom is more dependent on the GPU.

In Doom, the CPU's role appears to be secondary. At 1080p Low, the system achieves 181 FPS, which is high enough that CPU overhead could become relevant, but the frame rates scale down smoothly with resolution rather than showing a plateau that would indicate CPU limits. The 5.10 GHz boost clock and 65 W TDP suggest efficient single-thread performance, which is critical for FPS games that rely on a primary game thread. The data does not show any metric that would indicate the CPU is holding back the RTX 4080, even at the highest frame rates measured.

Measured FPS Breakdown

At 1920x1080, the full range of settings produces a wide spread of results. Low averages 181 FPS, which is the highest frame rate in the entire dataset. Medium averages 113 FPS with a minimum of 96 FPS and a maximum of 130 FPS, showing tight frame pacing. High averages 76 FPS, and Ultra averages 47 FPS — a dramatic fall from Low, suggesting that the Ultra preset's additional effects nearly halve performance.

At 2560x1440, Low averages 114 FPS, still well above the 60 FPS threshold. Medium averages 71 FPS with a minimum of 61 FPS and maximum of 82 FPS, maintaining playability. High averages 48 FPS, which is borderline, and Ultra averages 30 FPS, which is marginal for a fast-paced shooter. The pattern of roughly 37% reduction from Low to Medium and further drops to High and Ultra holds consistently.

At 3840x2160, the results are the most constrained. Low averages 60 FPS, exactly at the threshold for smooth play. Medium averages 37 FPS with a minimum of 32 FPS and maximum of 43 FPS, showing significant variance. High averages 25 FPS, and Ultra averages 16 FPS, both of which are unsuitable for competitive or even casual play. The 4K Medium minimum of 32 FPS indicates that even the "average" figure includes dips that would be noticeable.

How This Combo Ranks

This combination of AMD Ryzen 5 7600 and NVIDIA GeForce RTX 4080 ranks 3299 out of 3712 tested combos in Doom, placing it in the 11th percentile of all configurations. This is a surprisingly low ranking for a system with a high-end GPU, but the measured frame rates — particularly at 4K Ultra (16 FPS) and 4K High (25 FPS) — drag the overall standing down. The ranking suggests that many other CPU/GPU pairings achieve higher frame rates in this specific title, likely because Doom's engine is optimized for a different balance of components.

The GPU's own benchmark percentile of 86% and the CPU's 78% percentile suggest that both components are above average individually, yet their combined performance in Doom does not translate to a top-tier ranking. The nearest rival comparisons for the GPU show deltas of less than 3% in synthetic tests, but the in-game results are what matter for this ranking. The data indicates that while this combo is capable of high frame rates at lower resolutions, its 4K performance is a significant weak point, and the ranking reflects that the system is not optimized for the most demanding scenarios in Doom.
