Doom

The AMD Ryzen 7 5700X paired with the AMD Radeon RX 580 presents a classic study in bottleneck dynamics when running Doom. The data shows a system where the GPU is the clear limiting factor at higher resolutions, while the CPU’s strong multi-threading capabilities ensure it never becomes the primary constraint. This combination delivers playable frame rates at 1080p, but struggles to maintain smooth performance as resolution scales upward.

Resolution Scaling

The measured FPS data reveals a steep performance cliff as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate drops from 78.3 FPS at 1080p to 47.3 FPS at 1440p, and finally to 25.3 FPS at 4K. This represents a 68% reduction in performance from the lowest tested resolution to the highest, a pattern that strongly indicates the GPU is the limiting component. The RX 580’s 256-bit memory bus and 256.0 GB/s bandwidth are simply not sufficient to feed the pixel throughput demanded by 4K rendering in Doom.

The scaling behavior across settings at each resolution reinforces this conclusion. At 4K, the difference between Low and Ultra settings is substantial: 36.4 FPS versus 20.4 FPS, a 44% performance gap. Interestingly, the step from Medium to High at 4K yields only a 3.2 FPS difference (28.5 to 25.3), suggesting that the GPU is already saturated and additional graphical fidelity has diminishing returns. At 1080p, the same settings spread is much wider—105.7 FPS at Low versus 64.2 FPS at Ultra—indicating that the GPU has more headroom to work with when pixel count is lower.

The resolution scaling data shows that this combo is best suited for 1080p gaming. At 1440p, the frame rates dip into the 37-64 FPS range depending on settings, which is playable but not ideal for fast-paced FPS action. The 4K results are uniformly below 40 FPS, making them unsuitable for competitive play. The pattern is consistent: as resolution increases, the RX 580’s 6.175 TFLOPS of FP32 compute and 32 ROPs become increasingly overwhelmed.

CPU Role

The Ryzen 7 5700X brings substantial processing power to this pairing, and the benchmark results indicate it is more than capable of keeping up with the RX 580 in Doom. With 8 cores and 16 threads based on the Zen 3 architecture, this CPU delivers strong multi-threaded performance. The Cinebench R23 multicore score of 22620 and Passmark multithread score of 26612 demonstrate its capability to handle multiple concurrent tasks, which is relevant for Doom’s rendering pipeline that can utilize multiple threads.

The CPU’s clock speeds range from a 3.40 GHz base to a 4.60 GHz boost, with a 65 W TDP that keeps thermal demands modest. The 32 MB of shared L3 cache provides ample fast-access storage for game data, and the dual-channel DDR4 memory support with 51.2 GB/s bandwidth ensures the GPU receives data without significant CPU-side delays. The 3DMark 16-thread score of 6858 and max-thread score of 6850 show consistent scaling across thread counts, meaning the CPU maintains efficiency even under heavy multi-threaded loads.

In the context of this specific game, the CPU’s single-thread performance is also solid—the Cinebench R23 single-core score of 3193 and Passmark single-thread score of 3385 indicate that even scenarios relying on fewer threads will not bottleneck the GPU. The CPU’s percentile rank of 83 among all tested CPUs places it well above the median, and its average benchmark score of 26214 is nearly identical to the Intel Core i9-11900KF (26196, 0.1% delta) and AMD Ryzen 5 7600X (26272, -0.2% delta). This near-parity with newer and more expensive processors suggests the 5700X is not the weak link in this combo.

GPU Role

The AMD Radeon RX 580 is the primary performance limiter in this configuration, and the data makes this clear. Built on the Polaris 20 chip with GCN 4.0 architecture, this GPU features 2304 shading units, 144 texture mapping units, and 32 ROPs. Its 8 GB of GDDR5 memory on a 256-bit bus provides 256.0 GB/s of bandwidth, which is adequate for 1080p but becomes a constraint at higher resolutions. The base clock of 1257 MHz and boost clock of 1340 MHz are modest by modern standards, and the 185 W TDP reflects the older 14 nm manufacturing process from GlobalFoundries.

The GPU’s benchmark results show it sits in the middle of the pack, with a percentile rank of 53 among all tested GPUs. Its Passmark G3D score of 8813 and 3DMark Steel Nomad DX12 score of 1005 highlight its DirectX 12 capabilities, which are relevant for Doom’s modern rendering features. The Geekbench Vulkan score of 45173 indicates respectable API support for Vulkan, which Doom can leverage for improved performance. However, the GPU’s nearest rivals in the benchmark database—the NVIDIA GeForce GTX 570 (13564, 0% delta) and GTX 950 (13549, 0.1% delta)—are older and less capable cards, underscoring the RX 580’s dated positioning.

The GPU’s 8 GB VRAM is not the limiting factor in Doom, as the game’s texture requirements at 1080p and 1440p are well within this capacity. Instead, the bottleneck is raw compute throughput. The pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s are simply insufficient for 4K rendering, which requires processing four times the pixel count of 1080p. The FP32 performance of 6.175 TFLOPS, while respectable for its era, falls short of what modern FPS games demand at high resolutions.

How This Combo Ranks

The data places this combination at rank 1572 out of 1681 tested combos in Doom, placing it in the bottom 6.5% of all configurations. This low ranking is primarily attributable to the GPU’s modest capabilities, as the CPU performs admirably in isolation. The combo’s ranking reflects the reality that while the Ryzen 7 5700X is a strong processor, the RX 580 holds back the overall gaming experience.

This ranking becomes clearer when examining the GPU’s position among its peers. With an average benchmark score of 13559, the RX 580 is within 1.1% of the AMD Radeon Pro 455 (13416) and within 0.1% of the GTX 950 (13549). These are all older or lower-tier GPUs, and none would be expected to deliver high frame rates in modern FPS titles at high resolutions. The combo’s rank is therefore more a reflection of the GPU’s age than any deficiency in the CPU.

For context, the CPU alone ranks in the 83rd percentile, while the GPU sits in the 53rd percentile. This mismatch means the system is unbalanced, with the CPU capable of supporting a significantly more powerful GPU. The data suggests that upgrading the graphics card would yield substantial performance improvements, as the 5700X has ample headroom to feed a more capable GPU without becoming a bottleneck itself.

Measured FPS Breakdown

At 1920x1080, the combo delivers playable performance across all settings. Low settings achieve an average of 105.7 FPS, Medium settings reach 90.1 FPS, and High settings maintain 78.3 FPS. Ultra settings drop to 64.2 FPS, which is still smooth for single-player gameplay but may feel slightly less responsive in competitive multiplayer scenarios. The spread from Low to Ultra is 41.5 FPS, showing that the GPU has enough headroom at this resolution to accommodate significant graphical improvements.

Moving to 2560x1440, the performance drops become more pronounced. Low settings average 63.8 FPS, Medium settings hit 56.8 FPS, and High settings manage 47.3 FPS. Ultra settings fall to 37.8 FPS, which is below the threshold for smooth gameplay in a fast-paced FPS. The gap between Low and Ultra narrows to 26 FPS, indicating the GPU is starting to saturate. At this resolution, players would need to compromise on visual quality to maintain acceptable frame rates.

At 3840x2160, the results are largely unplayable for competitive play. Low settings achieve 36.4 FPS, Medium settings drop to 28.5 FPS, High settings manage 25.3 FPS, and Ultra settings fall to 20.4 FPS. The difference between Low and Ultra is just 16 FPS, demonstrating that the GPU is severely bottlenecked and additional settings changes have minimal impact. This resolution is clearly unsuitable for this combo in Doom, as even the lowest settings fail to reach 40 FPS.

The data across all three resolutions shows a consistent pattern: the RX 580 provides diminishing returns as resolution increases, while the Ryzen 7 5700X remains capable throughout. For 1080p gaming, this combo is a viable option, particularly at Medium or High settings where frame rates remain above 78 FPS. At 1440p, players must accept lower settings to maintain smooth performance, and at 4K, the combo falls short of playable frame rates regardless of settings.
