Doom

The AMD Ryzen 5 5600GT paired with the NVIDIA GeForce RTX 3080 Ti delivers a wide range of frame rates in Doom, from 315.1 FPS at 1080p Low to 69.2 FPS at 4K Ultra. The measured data, drawn from a 1681-combo database, places this pairing at rank 422, indicating a strong but not top-tier configuration for this title. The following analysis breaks down how resolution, GPU, and CPU characteristics shape the observed performance.

Resolution Scaling

The measured FPS values show a clear and consistent drop as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate falls from 315.1 FPS at 1080p to 201.5 FPS at 1440p, and further to 112.5 FPS at 4K. The same pattern holds for every preset: High goes from 231.1 to 148.1 to 82.8; Medium from 271.6 to 177.8 to 98.1; Ultra from 189.6 to 119.9 to 69.2. The magnitude of the drop between 1080p and 1440p is roughly similar to the drop between 1440p and 4K, though the absolute numbers shrink at higher resolutions.

This scaling behavior indicates that the GPU becomes the dominant limiting factor as pixel count rises. At 1080p, the frame rates are high enough that the CPU’s ability to feed the graphics card is likely the ceiling; at 4K, the GPU’s raw throughput is the primary constraint. The fact that even at 4K Low the system still produces 112.5 FPS suggests the RTX 3080 Ti has ample headroom for this game, but the Ultra preset at 4K drops to 69.2 FPS, which is still playable but not high-refresh territory. The data does not show any resolution where the CPU becomes a bottleneck severe enough to cap performance below the GPU’s capability.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is built on the Ampere architecture with a GA102 chip, featuring 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. Its boost clock is 1665 MHz, and it contains 10240 shading units, 320 TMUs, and 112 ROPs. The card’s average benchmark score is 41224, placing it in the 83rd percentile of all GPUs. Its nearest rival, the RTX 3090, has an average score of 41441, a delta of -0.5%, meaning the 3080 Ti trails by half a percent. The RTX 5070 sits 1.1% higher, and the Tesla M40 is 1.6% higher, but those differences are small in absolute terms.

In Doom, the GPU’s memory bandwidth and capacity are more than sufficient. At 4K Ultra, the 12 GB VRAM and 912.4 GB/s bandwidth handle the game’s textures without issue, as evidenced by the 69.2 FPS result. The card’s pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s contribute to the high frame rates at lower resolutions. The measured FPS at 1080p Low (315.1) and 1440p Low (201.5) show that the GPU is not the limiting factor at those settings; the CPU or game engine likely caps the output. The RTX 3080 Ti’s position relative to the RTX 3090 (0.5% lower average score) is consistent with the observed performance, which is strong but not the absolute fastest.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on Zen 3 (Cezanne) architecture, with a base clock of 3.60 GHz and a boost clock of 4.60 GHz. It has 16 MB of L3 cache and supports DDR4 memory in dual-channel mode. Its average benchmark score is 20740, placing it in the 78th percentile of all CPUs. The nearest rival, the Intel Core i7-10700, has an identical average score (20746, delta 0%), while the Core i5-12490F is 0.3% higher and the Ryzen 5 5600X is 0.3% lower. The CPU’s single-thread performance is strong, as shown by a Cinebench R23 single-core score of 2438 and a Geekbench single-core score of 2035.

In Doom, the CPU’s role is most evident at 1080p, where frame rates exceed 300 FPS on Low settings. The 315.1 FPS result at 1080p Low suggests the CPU can feed the GPU well beyond typical display refresh rates. At 1440p and 4K, the GPU becomes the bottleneck, so the CPU’s impact diminishes. The 5600GT’s 6 cores and 12 threads are sufficient for this game, which is not heavily multithreaded. The CPU’s launch MSRP is $140, but that figure is not relevant to the performance analysis. The data shows that the CPU is not a limiting factor in any of the measured configurations, as the frame rates scale consistently with resolution and settings.

Settings Recommendations

Based on the measured FPS, the optimal preset depends on the target resolution and desired frame rate. At 4K, the High preset delivers 82.8 FPS, which is above the 60 FPS threshold for smooth gameplay, while Ultra drops to 69.2 FPS. Medium offers 98.1 FPS, providing a comfortable margin. For players prioritizing visual fidelity at 4K, High is a balanced choice; for higher frame rates, Medium is preferable. At 1440p, Ultra achieves 119.9 FPS, which is excellent for high-refresh monitors, and High reaches 148.1 FPS. At 1080p, even Ultra produces 189.6 FPS, so any preset is viable; Low reaches 315.1 FPS for competitive play. The data suggests that the RTX 3080 Ti can handle Ultra at 1440p and 1080p without issue, while 4K Ultra is the only setting that dips below 70 FPS.
