Doom

The AMD Ryzen 5 5600 and AMD Radeon RX 570 combination delivers a playable but heavily GPU-bound experience in Doom, with performance scaling that clearly identifies the graphics card as the limiting factor. The data shows a dramatic drop in frame rates as resolution increases, a pattern typical of a system where the GPU’s 4 GB memory and Polaris 20 chip are working at their limits.

Resolution Scaling

The frame rate progression across resolutions is steep and telling. At 1920x1080 with Low settings, the combo averages 94.2 FPS, which drops to 65.6 FPS at High settings—a 30% reduction just from changing quality presets. Moving up to 2560x1440, the average at Low is 57.4 FPS, and at 4K (3840x2160) it falls to 34.3 FPS on Low. The scaling from 1080p Low to 4K Low represents a 64% drop in performance, from 94.2 to 34.3 FPS.

This pattern indicates the GPU is the primary constraint. The Ryzen 5 5600, with its 6 cores and 12 threads, is more than capable of feeding frames at these rates. The CPU’s benchmark scores—like 18309 in Cinebench R23 multicore and 2584 in single-core—suggest it has ample headroom for Doom’s demands. The RX 570, however, with its 4 GB of GDDR5 memory and 224.0 GB/s bandwidth, struggles as pixel count increases. The gap between Low and Ultra settings at each resolution also widens: at 1080p, the difference between Low and Ultra is 39.8 FPS (94.2 vs 54.4), while at 1440p it is 23.2 FPS (57.4 vs 34.2) and at 4K it is 12.3 FPS (34.3 vs 22.0). This shrinking delta suggests that at higher resolutions, the GPU is so saturated that even reducing settings yields diminishing returns.

How This Combo Ranks

In the grand scheme of tested hardware, this pairing sits near the bottom. The combo ranks 1635 out of 1681 tested combinations in Doom, placing it in the bottom 3% of all systems evaluated. This low ranking is not a reflection of the CPU, which performs admirably in isolation—the Ryzen 5 5600 holds the 79th percentile among all CPUs. Rather, it is the GPU dragging the overall score down.

The RX 570’s average benchmark score of 30158 places it in the 74th percentile of all GPUs, but its nearest rivals in the data are telling. The NVIDIA GeForce RTX 5060 scores 30109, a delta of 0.2%, and the AMD Radeon RX 7700 XT scores 30097, also a 0.2% delta. These are modern, high-end cards that should theoretically be far ahead, yet the benchmark data shows them clustered together. This suggests the average benchmark score is not fully capturing gaming performance in Doom, where the RX 570’s older architecture and limited VRAM become more pronounced. The CPU’s nearest rivals—the Intel Xeon D-1746TER at 21635 (0.6% delta) and the AMD EPYC 9554P at 21899 (-0.6% delta)—are server-class parts, indicating the Ryzen 5 5600’s gaming strength is not reflected in raw multi-threaded workloads alone.

GPU Role

The Radeon RX 570 is the decisive component in this system. Its 4 GB of GDDR5 memory is the most obvious limitation, especially at 4K where the frame rates collapse to 22.0 FPS on Ultra. The memory clock runs at 1750 MHz with 7 Gbps effective speed, and the 256-bit bus provides 224.0 GB/s of bandwidth. These are modest figures by modern standards, and Doom’s texture-heavy environments can exceed the VRAM capacity at higher resolutions, causing stutter and frame drops.

Clock speeds are equally telling. The GPU has a base clock of 1168 MHz and a boost clock of 1244 MHz. These are low compared to more recent architectures, but the chip itself—Polaris 20 on a 14 nm process from GlobalFoundries—is from 2017. The shading units number 2048, with 128 TMUs and 32 ROPs, yielding a pixel rate of 39.81 GPixel/s and a texture rate of 159.2 GTexel/s. The FP32 performance of 5.095 TFLOPS is adequate for 1080p gaming but falls short at higher resolutions. The data shows that at 1080p Medium settings, the combo achieves 80.7 FPS, which is smooth, but the GPU’s 150 W TDP and 450 W suggested PSU indicate it is not designed for high-end 4K workloads.

Measured FPS Breakdown

At 1920x1080, the combo performs best. Low settings yield an average of 94.2 FPS, Medium drops to 80.7 FPS, High to 65.6 FPS, and Ultra to 54.4 FPS. These are playable numbers for most gamers, especially given that Doom is a fast-paced FPS where higher frame rates matter. The 1080p results show a range of 39.8 FPS between the lowest and highest settings, giving users flexibility to prioritize visual quality or performance.

Stepping up to 2560x1440, the averages are 57.4 FPS on Low, 51.3 FPS on Medium, 44.8 FPS on High, and 34.2 FPS on Ultra. The drop from 1080p to 1440p is significant—at High settings, the frame rate falls from 65.6 to 44.8 FPS, a 32% reduction. This suggests that 1440p gaming is only viable on lower settings, and even then, the experience is not buttery smooth.

At 3840x2160, the results are mostly unplayable. Low settings average 34.3 FPS, Medium drops to 28.1 FPS, High to 21.7 FPS, and Ultra to 22.0 FPS. The difference between High and Ultra at 4K is negligible (0.3 FPS), indicating the GPU is completely bottlenecked regardless of quality settings. Even at Low, the 34.3 FPS average is below the 60 FPS threshold most gamers desire, making 4K a non-starter for this combination.

FAQ

*Q: What is the best resolution to play Doom with this CPU/GPU combo?*

A: The data shows 1920x1080 is the only resolution where the combo consistently exceeds 60 FPS. At Medium settings, it averages 80.7 FPS, and even at High, it maintains 65.6 FPS. Higher resolutions fall below playable thresholds.

Q: How does the Ryzen 5 5600 compare to its nearest CPU rivals?

A: The Ryzen 5 5600 has an average benchmark score of 21765, which is 0.6% higher than the Intel Xeon D-1746TER (21635) and 0.6% lower than the AMD EPYC 9554P (21899). It also trails the Intel Core i7-11700F (21957) by 0.9%.

*Q: Is 4 GB of VRAM sufficient for Doom at 4K?*

A: No. The 4K results show an average of 21.7 FPS at High settings and 22.0 FPS at Ultra. The GPU’s 4 GB GDDR5 memory and 224.0 GB/s bandwidth are insufficient to handle the texture load, resulting in sub-30 FPS performance.

Q: What is the frame rate difference between Low and Ultra at 1440p?

A: At 2560x1440, Low settings average 57.4 FPS while Ultra drops to 34.2 FPS, a difference of 23.2 FPS. This indicates that visual quality settings have a substantial impact at this resolution.

Q: How does the RX 570 compare to its nearest GPU rivals in synthetic benchmarks?

A: The RX 570’s average benchmark score is 30158. The NVIDIA GeForce RTX 5060 is 0.2% behind at 30109, and the AMD Radeon RX 7700 XT is also 0.2% behind at 30097. The NVIDIA Tesla M60 trails by 0.6% with a score of 29969.

Q: Can this combo achieve 60 FPS at 1080p with Ultra settings?

A: No. At 1920x1080 with Ultra settings, the average frame rate is 54.4 FPS. To reach 60 FPS, users must drop to High settings, which average 65.6 FPS, or Medium settings, which average 80.7 FPS.
