Doom

The AMD Ryzen 5 5600GT pairs a 6-core, 12-thread Zen 3 design with a 4.60 GHz boost clock, placing it in the 78th percentile of all CPUs tested. Its average benchmark score of 20740 is virtually identical to the Intel Core i7-10700, which scores 20746, and the AMD Ryzen 5 5600X, which scores 20680, with deltas of 0% and 0.3% respectively. In Doom, this CPU is more than sufficient; the game’s demands are met comfortably by the 5600GT’s 16 MB of L3 cache and architecture built on the 7 nm process. The data shows that at 1080p with Low settings, the system achieves 316.8 FPS, a figure that far exceeds what the display pipeline can typically present, indicating the CPU is not a bottleneck even at the lowest resolution where CPU load is proportionally highest. The single-thread performance, evidenced by a Geekbench single-core score of 2035, is robust enough to handle the game’s main thread logic, while the multi-threaded score of 7986 ensures background tasks do not interfere with frame pacing. The 65 W TDP and DDR4 memory support are consistent with a mid-range platform that does not constrain this game’s performance.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 is the dominant component in this pairing, built on the Ada Lovelace architecture with a 5 nm process. Its 12 GB of GDDR6X memory on a 192-bit bus delivers 504.2 GB/s of bandwidth, which is ample for Doom’s texture-heavy environments at all tested settings. The GPU’s boost clock of 2475 MHz and 5888 shading units provide the raw compute necessary to drive the frame rates observed. The data indicates that the RTX 4070 is the primary scaling factor: as resolution increases from 1920x1080 to 3840x2160, the average FPS drops proportionally, which is the signature of a GPU-limited scenario. For instance, at High settings, the card produces 231.3 FPS at 1080p, 150.5 FPS at 1440p, and 78.6 FPS at 4K. This pattern holds across all settings, with the GPU’s 29.15 TFLOPS FP32 performance being the decisive factor. The RTX 4070 sits in the 81st percentile of all GPUs, with an average benchmark score of 37283, placing it near the AMD Radeon RX Vega 56, which scores 37507, a delta of -0.6%. The card’s 200 W TDP is a secondary consideration; the benchmark results confirm that the GPU is consistently the limiting component, especially at Ultra settings where 4K drops to 63.6 FPS, a 37% reduction compared to High settings at the same resolution.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the database of tested combinations, this specific pairing of the AMD Ryzen 5 5600GT and NVIDIA GeForce RTX 4070 achieves a rank of 443 out of 1681 combos for Doom. This places it in the top 26% of all systems tested, which is a strong showing given that the CPU is a budget-oriented part while the GPU is a high-end offering. The rank reflects that the RTX 4070 carries the system’s performance, as the CPU’s average benchmark score of 20740 is only 0.3% above the AMD Ryzen 5 5600X, yet the combo’s in-game results are driven by the GPU’s capabilities. Compared to other combos in the database, this system is positioned well for high-refresh-rate 1440p gaming, as the measured FPS at that resolution exceeds 119.8 FPS even at Ultra settings. The gap between this combo and the top-ranked systems is primarily due to CPU-bound scenarios at lower resolutions; however, the data shows that at 4K, the GPU becomes the sole bottleneck, and the CPU’s rank becomes irrelevant to the final FPS. The 443rd rank is a composite measure, and the breakdown by resolution reveals that the system’s relative standing improves as resolution increases, since the RTX 4070’s raw throughput is what matters most.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of performance across three resolutions and four quality presets. At 1920x1080, the system delivers 316.8 FPS on Low, 275.7 FPS on Medium, 231.3 FPS on High, and 190.5 FPS on Ultra. These numbers indicate that even at the highest quality setting, the frame rate is more than double the refresh rate of a typical 144 Hz monitor, making the CPU’s 6 cores sufficient to avoid any limitations. Moving to 2560x1440, the averages are 201.1 FPS on Low, 174.4 FPS on Medium, 150.5 FPS on High, and 119.8 FPS on Ultra. The transition from 1080p to 1440p results in a 36.5% drop in FPS at Low settings, which is consistent with the GPU handling more pixels. At 3840x2160, the performance curve steepens: 111.6 FPS on Low, 97.1 FPS on Medium, 78.6 FPS on High, and 63.6 FPS on Ultra. The drop from 1080p Low to 4K Low is 64.8%, demonstrating the RTX 4070’s limits at 4K. The data shows that the system is capable of 4K gaming at playable frame rates, but only on Low and Medium settings, where it stays above 97 FPS; High and Ultra dip below 80 FPS, which is acceptable for a single-player title but not ideal for competitive play. The variance between settings at each resolution is also telling: at 1080p, the difference between Low and Ultra is 126.3 FPS, while at 4K, the same difference is only 48 FPS, reinforcing that the GPU is the scaling factor.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The resolution scaling analysis reveals a clear GPU-bound behavior. From 1920x1080 to 2560x1440, the average FPS across all settings drops by a factor of approximately 1.5, which aligns with the pixel count increase of 1.78 times, indicating that the GPU is being utilized more efficiently at higher resolutions. The data shows that at Low settings, the system goes from 316.8 FPS at 1080p to 201.1 FPS at 1440p, a 36.5% reduction, and then to 111.6 FPS at 4K, a further 44.5% reduction from 1440p. This non-linear drop is typical of a GPU that becomes more saturated as resolution increases. At High settings, the progression is 231.3 FPS to 150.5 FPS to 78.6 FPS, with the 4K figure representing a 66% decrease from 1080p. The limiting component is unequivocally the RTX 4070, as the CPU’s performance headroom is evident from the fact that the 5600GT’s multi-threaded score of 17272 in Cinebench R23 is more than sufficient for this game’s engine. If the CPU were the bottleneck, the frame rates would plateau or drop more severely at 1080p, but the data shows a steady decline across all resolutions. The 4K Ultra result of 63.6 FPS is the lowest observed, and it underscores that the GPU’s 12 GB VRAM and bandwidth are adequate, but the compute throughput is the limiting factor. The scaling pattern indicates that for users targeting 4K, reducing settings from Ultra to High yields a 23.6% FPS increase, while dropping to Medium yields a 52.7% increase, which are actionable adjustments based on this data.
