Doom

The AMD Ryzen 5 7600 paired with the NVIDIA GeForce RTX 5080 delivers a performance profile in Doom that is dominated by the GPU at higher resolutions, while the CPU’s strong single-thread capabilities keep frame rates exceptionally high at 1080p. The measured data shows a clear and predictable scaling pattern that highlights where each component’s headroom lies.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial, revealing the expected shift in bottleneck. At 1080p with High settings, the combo produces 306 FPS on average. Moving to 1440p reduces that to 198 FPS, a 35% decrease. At 4K, the average falls to 107 FPS, which is 65% lower than the 1080p result. This steep decline indicates that the GPU is the limiting factor as resolution increases, with the RTX 5080’s raw throughput being taxed more heavily at higher pixel counts.

The scaling pattern across all settings tells a similar story. At Low settings, the frame rate goes from 409 FPS at 1080p to 269 FPS at 1440p and 146 FPS at 4K. The 4K Low result is 64% lower than the 1080p Low result, which is nearly identical to the drop seen at High settings. This consistency suggests that even when graphical load is minimized, the GPU still becomes the primary constraint at 4K, rather than the CPU or memory subsystem.

Medium settings show the same trend with slightly different magnitudes. The 1080p Medium average is 363 FPS, dropping to 235 FPS at 1440p and 127 FPS at 4K. The 4K Medium result includes a measured minimum of 108 FPS and a maximum of 146 FPS, indicating some variance in demanding scenes. Ultra settings produce the lowest frame rates across the board: 250 FPS at 1080p, 162 FPS at 1440p, and 88 FPS at 4K. The 4K Ultra figure is 65% below the 1080p Ultra figure, again confirming the GPU-bound nature of the game at high resolutions.

The data also shows that resolution scaling is not perfectly linear. From 1080p to 1440p, the average drop across all settings is roughly 36%, while from 1440p to 4K, the average additional drop is about 46%. This non-linearity is typical of GPU-bound scenarios where pixel count grows faster than frame rate can compensate. At 4K, the RTX 5080 is clearly working near its limits in this title, while at 1080p, the Ryzen 5 7600’s single-core performance allows frame rates to climb well beyond what most displays can even show.

How This Combo Ranks

Among the 3,712 tested CPU-GPU combinations in this database, this pairing ranks 190th for Doom. That places it in the top 5% of all tested combos, which is an impressive showing for a mid-range CPU paired with a high-end GPU. The rank reflects the combined capability of both components working together in this specific title, and the data indicates that the RTX 5080 is doing most of the heavy lifting at higher resolutions while the Ryzen 5 7600 provides enough processing power to avoid becoming a serious bottleneck at 1080p.

The CPU’s individual benchmark performance supports this interpretation. The Ryzen 5 7600 has an average benchmark score of 26,324, which places it in the 78th percentile against all CPUs. Its nearest rivals include the AMD Ryzen 9 6900HX with a score of 26,274 (0.2% lower), the AMD Ryzen 7 7435HS with 26,402 (0.3% higher), the Intel Core i9-11900KF with 26,212 (0.4% lower), and the AMD Ryzen 5 8540U with 26,187 (0.5% lower). These deltas are all under 1%, meaning the Ryzen 5 7600 sits in a very tight performance cluster among its peers.

For the GPU, the RTX 5080 achieves an average benchmark score of 56,083, placing it in the 87th percentile against all GPUs. Its nearest rivals show a wider spread: the AMD Radeon 8060S scores 55,757 (0.6% higher), the AMD Radeon RX 6750 GRE 12 GB scores 55,698 (0.7% higher), the AMD Radeon Pro W5700X scores 54,828 (2.3% higher), and the AMD Radeon RX 9070 GRE scores 57,367 (2.2% lower). The fact that the RTX 5080 is sandwiched between older AMD cards and a newer AMD card in these aggregate benchmarks suggests that its raw compute power is competitive, but the measured FPS in Doom shows it pulling ahead more clearly than the aggregate scores might imply.

The combo rank of 190 out of 3,712 indicates that this pairing outperforms the vast majority of tested systems despite the CPU being relatively modest. This is largely because Doom’s engine scales well with GPU resources, and the Ryzen 5 7600’s 6 cores and 12 threads are sufficient to feed the RTX 5080 at most settings. The data shows that only 189 other combinations deliver higher frame rates in this game, which is a strong endorsement of this specific pairing for anyone targeting high-refresh-rate gameplay.

GPU Role

The NVIDIA GeForce RTX 5080 is built on the Blackwell 2.0 architecture using TSMC’s 5 nm process, with 45,600 million transistors packed into a 378 mm² die. It features 10,752 shading units, 336 texture mapping units, and 112 raster output pipelines. The GPU operates at a base clock of 2295 MHz and a boost clock of 2617 MHz, with memory clocked at 1875 MHz running at 30 Gbps effective. This configuration delivers a pixel rate of 293.1 GPixel/s and a texture rate of 879.3 GTexel/s, with FP32 compute rated at 56.28 TFLOPS.

The memory subsystem consists of 16 GB of GDDR7 on a 256-bit bus, providing 960.0 GB/s of bandwidth. This is a substantial amount of bandwidth for a modern GPU, and it plays a critical role in Doom’s performance at 4K. The game’s texture-heavy environments and fast-paced action benefit from the high memory throughput, allowing the GPU to maintain consistent frame delivery even when large assets are being streamed. The 16 GB capacity is also generous for this 2016 title, ensuring that VRAM is never a limiting factor at any resolution or settings preset.

The measured results show that the RTX 5080’s performance scales predictably with settings. At 4K, the average frame rate drops from 146 FPS at Low to 127 FPS at Medium, 107 FPS at High, and 88 FPS at Ultra. This represents a 40% reduction from Low to Ultra, which aligns with the GPU’s raw compute limits. The boost clock of 2617 MHz allows the GPU to maintain high utilization across all settings, and the data suggests that the card is rarely idle due to CPU constraints at higher resolutions.

At 1080p, the GPU’s role is less dominant. The RTX 5080 produces 409 FPS at Low, 363 FPS at Medium, 306 FPS at High, and 250 FPS at Ultra. These numbers are extremely high, and the scaling from Low to Ultra shows a 39% drop, similar to the 4K pattern. However, the absolute values indicate that the GPU is not the sole bottleneck at 1080p; the CPU’s frame generation capability begins to factor in, especially at Lower settings where the GPU has more headroom. The Ryzen 5 7600’s single-thread performance, as evidenced by its 3DMark single-thread score of 999, becomes more relevant at these frame rates.

The boost clock of 5.10 GHz provides the single-thread performance needed for the game’s main game logic and physics, while the 6 cores handle background processes without causing frame dips. The L3 cache of 32 MB helps with data locality, reducing memory latency in fast-paced scenes.

At higher resolutions, the CPU’s workload remains relatively constant while the GPU’s load increases. The data shows that the frame rate drops are proportional to resolution scaling, which indicates the CPU is not introducing additional bottlenecks beyond what the GPU demands. The 65 W TDP also means the CPU can sustain its boost clocks for extended periods without thermal throttling, ensuring consistent performance across long gaming sessions. The Ryzen 5 7600’s 78th percentile ranking against all CPUs confirms that it is a competent gaming processor, even if it is not the top-tier option for heavily threaded workloads.

Settings Recommendations

For the best balance of visual quality and performance, the High preset at 1440p is the recommended starting point. The combo delivers 198 FPS on average, which is well above the refresh rate of most gaming monitors. This preset provides a significant visual upgrade over Medium while still maintaining frame rates that are smooth and responsive. The data shows that High settings at 1440p offer the largest performance margin over the next step up, with Ultra dropping to 162 FPS.

For users with 4K displays, the Medium preset appears to be the optimal choice. It achieves 127 FPS on average with a measured minimum of 108 FPS, which ensures that frame pacing remains consistent even in demanding scenes. The Low preset at 4K delivers 146 FPS, but the visual quality reduction is likely not worth the 15% performance gain over Medium. The Ultra preset at 4K drops to 88 FPS, which is below the threshold for smooth gameplay on high refresh rate displays.

At 1080p, all settings presets produce frame rates above 250 FPS, so the choice depends on monitor refresh rate and visual preference. The High preset at 306 FPS is a solid choice for 240 Hz monitors, while the Ultra preset at 250 FPS still provides excellent performance for most displays. The Medium preset at 363 FPS offers a sweet spot for competitive play, where frame rate matters more than graphical fidelity.

The data suggests that the Ultra preset is not worth the performance cost at any resolution. At 4K, the drop from High to Ultra is 19 FPS (107 to 88), which represents an 18% reduction for what is likely a marginal visual improvement. At 1440p, the drop is 36 FPS (198 to 162), and at 1080p, the drop is 56 FPS (306 to 250). In all cases, the High preset provides better frame rates with only a minor reduction in visual quality. For the most competitive experience, the Low preset at 1440p delivers 269 FPS, which is ideal for high refresh rate monitors, though it sacrifices visual fidelity.
