Doom

The AMD Ryzen 5 5600GT paired with the NVIDIA GeForce RTX 5080 achieves a combo rank of 245 out of 3712 tested combinations for Doom. This places the pairing in the top 6.6% of all configurations tested, a strong showing that reflects the GPU’s dominance in this title. The RTX 5080 sits at the 87th percentile among all GPUs in the database, while the Ryzen 5 5600GT holds the 74th percentile among CPUs; the gap between those percentile positions explains why the GPU is the primary driver of the frame rates observed here, with the CPU providing sufficient support to avoid bottlenecking at most settings.

How This Combo Ranks

The 245th-place finish out of 3,712 combos is a decisive result, placing this system well ahead of the median configuration tested for Doom. To contextualize, the RTX 5080’s own benchmark average of 56,083 is nearly identical to its nearest rivals, with the AMD Radeon 8060S trailing by just 0.6% and the AMD Radeon RX 6750 GRE 12 GB sitting 0.7% behind. The gap to the AMD Radeon Pro W5700X is larger at 2.3%, while the AMD Radeon RX 9070 GRE actually leads by 2.2%. This clustering means the GPU’s performance class is tightly contested, yet in Doom specifically, the RTX 5080’s 16 GB of GDDR7 memory and Blackwell 2.0 architecture push it to frame rates that the rank reflects.

On the CPU side, the Ryzen 5 5600GT’s average benchmark score of 20,733 is effectively on par with its nearest rivals: the Intel Core i5-12490F is a mere 0.3% higher, and both the Intel Xeon 6325P and Intel Core Ultra 5 125U sit just 0.4% above. The AMD EPYC 7J13 leads by 0.5%. None of these differences are meaningful in gaming terms, confirming that the 5600GT delivers consistent performance in this tier. The combo’s high rank in Doom, therefore, is not a function of CPU superiority but rather the result of the GPU’s ability to maintain very high frame rates, especially at lower resolutions where the CPU’s 6 cores and 12 threads are sufficient to keep feeding the graphics pipeline.

GPU Role

The RTX 5080’s 16 GB of GDDR7 memory across a 256-bit bus delivers a bandwidth of 960.0 GB/s, a figure that is critical for Doom’s texture-heavy environments at 4K. The card’s base clock runs at 2295 MHz with a boost of 2617 MHz, and the memory operates at an effective 1875 MHz (30 Gbps). These clocks, combined with 10,752 shading units and 112 ROPs, produce a pixel rate of 293.1 GPixel/s and a texture rate of 879.3 GTexel/s. In practical terms, the GPU’s FP32 throughput of 56.28 TFLOPS is the headline number for raw compute, but Doom’s engine is more sensitive to memory bandwidth and fill rate than to theoretical floating-point performance.

Benchmark results show the GPU’s PassMark G3D score of 36,565 is strong, but more telling are the DirectX scores: DirectX 11 yields 324, DirectX 12 drops to 151, and DirectX 10 sits at 208. These numbers suggest that Doom, which uses OpenGL and Vulkan APIs per the GPU’s supported feature set (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), may not fully leverage the RTX 5080’s newest features. The measured FPS data confirms the GPU is the limiting factor at 4K Ultra, where the average drops to 88 FPS, but at 1080p Low, the 350 FPS average indicates the GPU has enormous headroom that the CPU and game engine cannot fully utilize. The 16 GB VRAM capacity is never a constraint in the measured scenarios, as even the most demanding 4K Ultra preset does not approach capacity limits, but the bandwidth is heavily utilized when resolution scales up.

Settings Recommendations

The measured FPS data for this combo provides clear guidance on settings selection. At 1080p, all presets exceed 250 FPS, with Low hitting 350, Medium at 334, High at 306, and Ultra at 250. The Medium preset’s minimum FPS of 284 ensures smooth gameplay even in demanding scenes, making it a safe choice for high-refresh-rate monitors. At 1440p, the spread narrows but remains ample: Low produces 269 FPS, Medium 235, High 198, and Ultra 162. For 4K, the differences become more pronounced: Low yields 146 FPS, Medium 127, High 107, and Ultra drops to 88 FPS. The Medium preset at 4K, with its recorded minimum of 108 FPS and maximum of 146 FPS, offers the best balance of visual quality and frame rate stability.

Given that Doom is a fast-paced FPS where frame time consistency matters, the data suggests that Medium is the optimal preset across all resolutions. At 1080p, Medium’s 334 FPS average is only 4.6% below Low but provides substantially better visuals, while its 284 FPS minimum remains well above typical 144Hz refresh rates. At 1440p, Medium’s 235 FPS average and 199 FPS minimum keep the experience fluid. The 4K Medium preset delivers 127 FPS on average, which is above the 120Hz threshold for many displays, and the 108 FPS minimum is acceptable for most users. Ultra presets are only recommended for users with G-Sync or FreeSync displays who prioritize image quality over maximum frame rates, as the 88 FPS average at 4K Ultra is the only measured scenario that drops below 100 FPS.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all presets. Low settings produce an average of 350 FPS, Medium 334 FPS with a minimum of 284 and maximum of 384, High 306 FPS, and Ultra 250 FPS. The progression from Low to Ultra shows a 28.6% reduction in average FPS, from 350 to 250, which is a modest penalty for the visual upgrade that Ultra provides. The Medium preset’s minimum-to-maximum spread of 100 FPS (284 to 384) indicates some scene-to-scene variance, but the average remains exceptionally high.

At 2560x1440, the averages drop predictably. Low settings yield 269 FPS, Medium 235 FPS with a minimum of 199 and maximum of 270, High 198 FPS, and Ultra 162 FPS. The Medium preset’s minimum of 199 FPS is notable because it stays above 200 FPS, ensuring that even the heaviest scenes do not cause stutter on 144Hz or 165Hz displays. The drop from Low to Ultra at this resolution is 39.8%, from 269 to 162 FPS, a larger penalty than at 1080p, which suggests the GPU is beginning to feel the resolution pressure.

At 3840x2160, the frame rates remain playable but show clear scaling limits. Low settings produce 146 FPS, Medium 127 FPS with a minimum of 108 and maximum of 146, High 107 FPS, and Ultra 88 FPS. The Medium preset’s minimum of 108 FPS is the only 4K measurement that stays above 100 FPS, making it the recommended choice for 4K gaming. The drop from Low to Ultra at 4K is 39.7%, consistent with the 1440p pattern, but the absolute values are much lower. The gap between Medium and High at 4K is 20 FPS (127 to 107), a 15.7% reduction, which is significant enough that users should weigh visual fidelity carefully.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the limiting component clearly. At Low settings, the average FPS goes from 350 at 1080p to 146 at 4K, a 58.3% reduction. At Medium, the drop is from 334 to 127, a 62.0% reduction. At High, 306 drops to 107, a 65.0% reduction. At Ultra, 250 drops to 88, a 64.8% reduction. These percentages are substantial, indicating that the GPU is the primary bottleneck as resolution increases. The fact that the percentage drop is relatively consistent across presets (ranging from 58.3% to 65.0%) suggests that the GPU’s fill rate and bandwidth are the limiting factors, not the CPU.

The CPU’s role in this scaling is minimal. The Ryzen 5 5600GT’s 6 cores and 12 threads, with a base clock of 3.60 GHz and boost of 4.60 GHz, are more than adequate for Doom at any resolution. Evidence of this is the 1080p Low result of 350 FPS, which is likely near the engine’s maximum frame rate ceiling rather than a CPU-bound limit. If the CPU were the bottleneck, we would expect to see smaller FPS differences between 1080p and 1440p, but the data shows a uniform scaling pattern. The 1440p to 4K drop is particularly telling: at Medium, 235 FPS at 1440p falls to 127 FPS at 4K, a 46.0% reduction that is purely GPU-driven. The 16 GB VRAM and 960.0 GB/s bandwidth are sufficient for 4K, but the 256-bit bus and the GPU’s raw compute are stretched by the pixel count.

A: The Ryzen 5 5600GT’s average score of 20,733 is 0.3% below the Intel Core i5-12490F and 0.4% below both the Intel Xeon 6325P and Intel Core Ultra 5 125U. The AMD EPYC 7J13 is 0.5% higher. These differences are negligible for gaming performance.

CPU Role

The Ryzen 5 5600GT’s contribution to Doom’s performance is supportive rather than dominant. Its 6 cores and 12 threads, based on the Zen 3 architecture codenamed Cezanne, operate at a base clock of 3.60 GHz and boost to 4.60 GHz. The 16 MB of L3 cache and 51.2 GB/s memory bandwidth are modest by modern standards but adequate for this game. The CPU’s PassMark multithread score of 20,325 and single-thread score of 3,348 reflect its mid-range positioning, yet Doom does not heavily stress multi-threading; the 3DMark single-thread score of 913 and 2-thread score of 1,794 are more relevant metrics for gaming.

The CPU’s 74th percentile ranking among all CPUs, with an average benchmark score of 20,733, places it in the upper-middle tier. Its nearest rival, the Intel Core i5-12490F, scores 20,802, a difference of just 0.3%, confirming that the 5600GT is not leaving performance on the table. In actual gaming, the FPS data shows no scenario where the CPU becomes the limiting factor. At 1080p Low, the 350 FPS average is likely constrained by the game engine’s frame rate cap or physics simulation, not by the CPU’s processing power. The 3DMark max-thread score of 5,554 and 16-thread score of 5,523 indicate that the CPU’s multi-threaded capabilities are consistent, but Doom primarily relies on fewer threads.

The CPU’s TDP of 65 watts and 7 nm process node mean it runs efficiently, allowing the RTX 5080 to operate without thermal throttling from a cramped case. The PCIe Gen 3 interface with 16 lanes is a potential concern for GPU bandwidth, but the measured FPS data does not show any negative impact from this limitation. The integrated Radeon Vega 7 graphics are not used in this combo, but their presence does not detract from the discrete GPU’s performance. Overall, the Ryzen 5 5600GT provides just enough CPU performance to keep the RTX 5080 fed at all resolutions, with the GPU taking over as the primary performance driver as resolution increases. Users seeking higher frame rates at 1080p Low would likely not benefit from a faster CPU, as the 350 FPS result suggests diminishing returns in this title.
