Doom

The AMD Ryzen 5 3600 and AMD Radeon RX 570 pairing in Doom presents a clear case of GPU-bound scaling. Moving from 1920x1080 to 3840x2160 effectively halves the frame rate. At High settings, the average FPS drops from 68 at 1080p to 44 at 1440p, then plunges to 24 at 4K. This linear degradation pattern—a 35% reduction from 1080p to 1440p, followed by another 45% drop to 4K—indicates the Polaris 20 GPU is the limiting component. The CPU, with its 6 cores and 12 threads, is not the bottleneck at higher resolutions. The data shows that at Ultra settings, the 4K average of 19 FPS is unplayable, while the 1080p Ultra average of 56 FPS remains fluid. The scaling behavior confirms that this combo is optimized for 1080p and 1440p gaming, where the RX 570’s 224.0 GB/s memory bandwidth can keep pace with the render load. At 4K, the GPU’s 32 ROPs and 5.095 TFLOPS of FP32 performance are simply insufficient to maintain acceptable frame rates, even with the CPU’s headroom.

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

The measured FPS data for Doom reveals a textbook GPU-limited scenario. At 1920x1080 with Low settings, the combo achieves 92 FPS, but this drops to 60 FPS at 2560x1440 and 32 FPS at 3840x2160. The scaling from 1080p to 1440p on Low settings is a 35% performance reduction, while moving from 1440p to 4K costs another 47%. This steep decline is characteristic of a graphics card struggling to fill the increasing pixel count. The RX 570’s 4 GB of GDDR5 memory on a 256-bit bus provides a theoretical bandwidth of 224.0 GB/s, which is the primary constraint at higher resolutions. The data shows that at 4K Medium, the average FPS is 28, with minimums of 24 and maximums of 32—a narrow band that suggests the GPU is hitting its memory bandwidth ceiling. Conversely, the Ryzen 5 3600’s 32 MB of shared L3 cache and 51.2 GB/s memory bandwidth are not the limiting factors here. The pattern across all settings levels confirms that the GPU’s 14 nm Polaris 20 chip, with its 2048 shading units and 128 TMUs, cannot sustain the fill rate demanded by 4K resolutions. For 1080p High settings, the 68 FPS average is respectable, but the 24 FPS at 4K High illustrates why this combination is not suited for 4K gaming.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the comprehensive benchmark database, this specific combination of AMD Ryzen 5 3600 and AMD Radeon RX 570 ranks 3547 out of 3712 tested combos for Doom. This places it in the bottom 5% of all configurations tested, which is a surprisingly low position given the individual component benchmarks. The CPU alone sits at the 71st percentile among all processors, while the GPU ranks at the 74th percentile among all graphics cards. Yet when combined, the pairing underperforms relative to its components’ individual standings. This discrepancy suggests that the RX 570, despite its respectable percentile ranking, is not well-suited to Doom’s rendering demands at higher settings. The combo rank of 3547 indicates that most other tested pairings—even those with ostensibly weaker components—achieve better performance in this specific title. The data shows the average FPS across all measured configurations is not provided, but the rank implies that 165 other combos perform worse. This makes the Ryzen 5 3600 + RX 570 a marginal setup for Doom, particularly when compared to more balanced pairings that pair the same CPU with a faster GPU or a stronger CPU with the same GPU.

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

The AMD Radeon RX 570’s specifications directly explain the measured performance in Doom. The GPU operates with a base clock of 1168 MHz and a boost clock of 1244 MHz, with memory clocked at 1750 MHz (7 Gbps effective). The 4 GB of GDDR5 memory on a 256-bit bus yields 224.0 GB/s of bandwidth. These figures are modest by modern standards, and the benchmark results reflect this. At 1080p Ultra, the average FPS is 56, which is playable but not smooth by competitive standards. The GPU’s pixel rate of 39.81 GPixel/s and texture rate of 159.2 GTexel/s are the key metrics that determine Doom’s performance. The game’s id Tech 6 engine relies heavily on texture streaming and high-resolution assets, which stresses the 4 GB VRAM capacity. The data shows that at 4K with High settings, the average drops to 24 FPS, and at 4K Ultra it falls to 19 FPS. This dramatic falloff beyond 1080p is consistent with the GPU’s memory subsystem becoming saturated. The 32 ROPs are insufficient for 4K resolution output, as each frame requires more pixel fill operations than the GPU can deliver. The FP32 performance of 5.095 TFLOPS is adequate for 1080p, but the benchmark results indicate that the Polaris 20 chip is pushed to its limits at higher resolutions. The GPU’s 150 W TDP and dual-slot design suggest it is a mid-range part, and its 74th percentile ranking among all GPUs confirms it sits in the upper-mid tier, yet Doom’s specific requirements expose its limitations.

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

The measured FPS data provides a comprehensive picture of performance across all resolution and settings combinations. At 1920x1080, the results range from 92 FPS on Low settings to 56 FPS on Ultra. The Medium settings produce an average of 80 FPS with minimums of 68 and maximums of 93, while High settings average 68 FPS. These 1080p numbers indicate a playable experience across all quality levels, with only the Ultra preset dipping below the 60 FPS threshold. Moving to 2560x1440, the performance degrades predictably: Low averages 60 FPS, Medium averages 52 FPS with a range of 44-60, High averages 44 FPS, and Ultra drops to 36 FPS. The 1440p results show that this combo can handle lower settings at this resolution, but High and Ultra settings fall below the 60 FPS mark. At 3840x2160, the situation becomes dire. Low settings average 32 FPS, Medium averages 28 FPS (range 24-32), High averages 24 FPS, and Ultra averages only 19 FPS. None of the 4K configurations achieve playable frame rates, and the data suggests that the GPU is the primary constraint. The gap between Low and Ultra settings widens as resolution increases: at 1080p, the difference is 36 FPS (92 vs 56), at 1440p it is 24 FPS (60 vs 36), and at 4K it is 13 FPS (32 vs 19). This narrowing gap indicates that at higher resolutions, the GPU’s raw compute power becomes the limiting factor rather than the settings level.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 3600 provides a solid foundation for Doom, though its influence on the measured results is largely secondary to the GPU. The 6-core, 12-thread processor with a base clock of 3.60 GHz and boost clock of 4.20 GHz offers ample processing power for this title. The CPU’s Zen 2 architecture, built on a 7 nm process from TSMC, delivers strong single-thread performance that is essential for game logic and draw call processing. In the benchmark data, the CPU scores 696 in the 3dmark single-thread test and 4605 in the 16-thread test, indicating balanced performance. The 32 MB of shared L3 cache is particularly beneficial for Doom’s level streaming, as it reduces memory latency. The CPU’s 71st percentile ranking among all processors suggests it is not the bottleneck in this configuration. The measured FPS data shows that at 1080p Low settings, the combo achieves 92 FPS, which is likely near the CPU’s maximum frame rate for this title. However, the fact that performance scales so poorly with resolution increases confirms that the GPU is the limiting component. If the CPU were the constraint, we would expect similar FPS across all resolutions at a given settings level. Instead, the dramatic drops from 1080p to 4K indicate that the Ryzen 5 3600 is feeding the GPU as fast as it can, but the RX 570 cannot process frames quickly enough. The CPU’s dual-channel DDR4 memory support with 51.2 GB/s bandwidth is sufficient for Doom, and its PCIe Gen 4 interface (though the GPU uses PCIe 3.0) ensures no bottleneck in data transfer.
