Doom

The AMD Ryzen 7 5800X3D and AMD Radeon RX 580 pairing in Doom presents a clear case of GPU-limited performance at higher resolutions, with the CPU’s substantial headroom only becoming apparent at 1080p. The data shows a system that is capable of smooth gameplay at 1080p, but struggles to maintain playable frame rates at 4K, regardless of settings. This combination ranks near the bottom of the tested combos, at 1550 out of 1681, indicating that while the CPU is a top-tier performer, the GPU holds this pairing back significantly in this title.

Resolution Scaling

The frame rate drop from 1080p to 4K is stark and reveals the primary bottleneck. At 1080p with Low settings, the combo achieves an average of 105.1 FPS. Moving to 1440p at the same settings, the average drops to 68.4 FPS, a reduction of 35%. At 4K with Low settings, the average plummets to 37 FPS, which is only 35% of the 1080p performance. This steep decline is a classic indicator of GPU saturation; the RX 580’s rendering pipeline is being overwhelmed by the increasing pixel count.

The scaling pattern is consistent across all settings. For instance, at High settings, the average FPS goes from 75.2 at 1080p, to 47.5 at 1440p, and finally to 25.8 at 4K. This near-linear drop with resolution is the signature of a graphics card that has reached its compute and memory bandwidth limits. The Ryzen 7 5800X3D, with its 8 cores and 16 threads, is not the limiting factor here; its job is to feed the GPU with draw calls, and at these resolutions, the GPU is taking far longer to render each frame than the CPU takes to prepare it.

The data suggests that the game is heavily reliant on the GPU's fill rate and memory bandwidth, which are specified at 42.88 GPixel/s and 256.0 GB/s respectively. At 4K, the demand for pixels and texture data exceeds what the RX 580 can deliver, making it the definitive performance ceiling. The transition from 1440p to 4K is particularly punishing, with the average FPS at High settings dropping by over 45%, confirming that 4K is not a viable target for this combo in Doom.

Settings Recommendations

For this specific hardware pairing, the optimal balance between visual fidelity and performance is found at 1080p with Medium settings. The data shows an average of 90.8 FPS at this configuration, which is comfortably above the 60 FPS threshold for smooth gameplay. Compared to High settings at the same resolution, which yields 75.2 FPS, Medium offers a 20% performance uplift. The jump to Low settings at 1080p provides a further boost to 105.1 FPS, but the visual cost is often not worth the extra frames when the Medium preset already provides a fluid experience.

At 1440p, the situation is more challenging. The only setting that maintains a playable average above 60 FPS is Low, which hits 68.4 FPS. Medium settings at 1440p drop to 56.2 FPS, which may be acceptable for some, but it is below the ideal target for a fast-paced FPS. High and Ultra settings at 1440p are not recommended, with averages of 47.5 and 40.8 FPS respectively, as they fall into a range where responsiveness is compromised.

At 4K, no setting provides a playable experience. Even at Low settings, the average FPS is only 37, which is below the minimum threshold for a playable experience in a game like Doom. The Ultra preset at 4K is the worst performer, with an average of 23.1 FPS, making it a slideshow. Therefore, the recommendation is clear: for a responsive experience, stick to 1080p with Medium or High settings; for 1440p, only the Low preset is viable; and 4K should be avoided entirely.

GPU Role

The AMD Radeon RX 580 is the determining factor in this combo's performance. Its specifications, including 2304 shading units, 144 texture mapping units, and 32 render output units, define its processing capacity. The GPU's boost clock of 1340 MHz and its 8 GB of GDDR5 memory on a 256-bit bus provide a bandwidth of 256.0 GB/s. In Doom, these resources are the primary constraint.

The benchmark results show that the GPU's performance is heavily taxed by the game's demands. Its PassMark G3D score of 8813 places it in the 53rd percentile of all GPUs, and its average benchmark score of 13559 is nearly identical to that of the NVIDIA GeForce GTX 570, which has a deltaPct of 0. This indicates that the RX 580 is a mid-range performer from its generation. The 8 GB VRAM is sufficient for the game's textures at 1080p and 1440p, but the sheer processing power needed to render Doom's fast-paced environments at higher resolutions is lacking.

The GPU's compute capabilities, measured at 6.175 TFLOPS for FP32, are the bottleneck. As resolution increases, the amount of pixel shading and texture work grows exponentially, and the RX 580 simply cannot keep up with the Ryzen 7 5800X3D's ability to issue commands. The data confirms this; the CPU is never the limiting factor, as evidenced by the significant frame rate drops when the GPU's workload increases.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo's capabilities across all settings and resolutions.

At 1920x1080, the combo delivers its best results. The Ultra preset averages 60.6 FPS, which is just above the playable threshold. High settings improve this to 75.2 FPS, Medium to 90.8 FPS, and Low to 105.1 FPS. This is the only resolution where all presets are at least playable.

At 2560x1440, performance degrades significantly. The Low preset is the only one to break the 60 FPS barrier, averaging 68.4 FPS. Medium averages 56.2 FPS, High drops to 47.5 FPS, and Ultra falls to 40.8 FPS. The gap between Low and Ultra at this resolution is 27.6 FPS, highlighting the GPU's sensitivity to graphical load.

At 3840x2160, the combo is not viable for competitive play. Low settings average 37 FPS, Medium drops to 32.1 FPS, High to 25.8 FPS, and Ultra to 23.1 FPS. The difference between Low and Ultra at 4K is only 13.9 FPS, showing that the GPU is so saturated that even reducing settings has diminishing returns. The scaling from 1080p Low to 4K Low shows a 68.1 FPS drop, which is a 65% reduction in performance.

How This Combo Ranks

This specific combination of the AMD Ryzen 7 5800X3D and AMD Radeon RX 580 ranks 1550 out of 1681 tested combos for Doom. This places it in the bottom 8% of all configurations. This low ranking is almost entirely attributable to the GPU, as the CPU is a high-end part.

The CPU's own benchmarks show it is a top performer, with an average benchmark score of 26574 and a percentile rank of 83 against all CPUs. It is competitive with the Intel Core i9-11900K, which has a deltaPct of 0.1, and the AMD Ryzen 5 7600, which has a deltaPct of -0.2. In contrast, the GPU's average benchmark score of 13559 places it in the 53rd percentile, with its nearest rival, the NVIDIA GeForce GTX 570, having a deltaPct of 0.

The low combo rank indicates that while the CPU is capable of supporting much higher frame rates, the GPU prevents this system from achieving them. In a game like Doom, which can be CPU-intensive at high frame rates, the 5800X3D is more than adequate, but the RX 580 is a severe bottleneck. The data suggests that pairing this CPU with a more powerful GPU would yield a significantly better result in this game.

CPU Role

The AMD Ryzen 7 5800X3D plays a supporting role in this pairing, providing ample processing power that goes largely unused due to the GPU's limitations. The CPU features 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.40 GHz and a boost clock of 4.50 GHz. It has a large 96 MB shared L3 cache, which is beneficial for gaming.

In synthetic benchmarks, the CPU demonstrates its strength. Its Cinebench R23 multicore score is 24063, and its single-core score is 3397. Its Geekbench multicore score is 11061, and its single-core score is 2116. These scores indicate that the CPU is capable of handling the game's logic and physics calculations with ease. The 3DMark scores, including 7299 for 16 threads and 5906 for 8 threads, further confirm its multi-threaded prowess.

However, in Doom, the CPU's performance is not the bottleneck. The evidence is in the resolution scaling. If the CPU were the limiting factor, the frame rates would be similar across different resolutions. Instead, the frame rates drop dramatically as resolution increases, which is the definition of a GPU bottleneck. The CPU is ready to deliver more frames, but the RX 580 cannot render them fast enough. This is a clear case of a high-end CPU being held back by a mid-range GPU, resulting in a system that is not well-balanced for this particular game at higher resolutions, despite being perfectly adequate at 1080p.
