Doom

Resolution Scaling

The measured frame rates for Doom with the AMD Ryzen 7 7700 and AMD Radeon RX 580 reveal a steep performance cliff as resolution climbs. At 1080p with Low settings, the combo averages 103 FPS, but that drops to 74.4 FPS at High and 61.5 FPS at Ultra, showing that even at the lowest resolution, the GPU is already the dominant constraint. Moving to 1440p, the decline continues: 68.4 FPS at Low, 60 FPS at Medium, 50.2 FPS at High, and 39.9 FPS at Ultra. The gap between Low and Ultra at 1440p is 28.5 FPS, which is a significant spread that indicates the graphics card's fill rate and memory bandwidth are being taxed heavily by the higher preset details.

At 4K, the picture becomes much harsher. The RX 580 manages only 36.3 FPS at Low, 29.3 FPS at Medium, 24.8 FPS at High, and 22.3 FPS at Ultra. The drop from 1080p Low to 4K Low is 66.7 FPS, a 64.8% reduction in performance. This pattern strongly suggests that the Radeon RX 580, with its 256-bit memory bus and 8 GB of GDDR5, is the limiting component in this pairing. The Ryzen 7 7700's strong single-thread performance, as evidenced by its 3dmark single-thread score of 1049, is not the bottleneck here; the GPU simply cannot keep up with the pixel throughput demanded at higher resolutions.

The scaling from 1440p to 4K is particularly telling. At High settings, the average FPS falls from 50.2 to 24.8, a 50.6% drop. This halving of performance is characteristic of a GPU that is saturated at 1440p and completely overwhelmed at 4K. Even the most favorable comparison — 1080p Low versus 4K Low — shows a 64.8% loss, which indicates that the RX 580's architecture, based on GCN 4.0 and manufactured on a 14 nm process, lacks the raw compute headroom for 4K gaming in Doom. The data points to a clear verdict: this combination is viable for 1080p gaming, acceptable for 1440p at lower presets, and not suitable for 4K beyond the lowest settings.

GPU Role

The AMD Radeon RX 580 is the clear performance limiter in this pairing. Its specifications paint a picture of a mid-range card from 2017: 2304 shading units, 144 texture mapping units, and 32 ROPs. The GPU clock speeds are listed at 1257 MHz base and 1340 MHz boost, with memory running at 2000 MHz (8 Gbps effective). The 8 GB of GDDR5 memory on a 256-bit bus provides 256.0 GB/s of bandwidth, which is adequate for 1080p but proves insufficient for 4K in Doom. The card achieves a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s, figures that explain the frame rate collapse at higher resolutions.

In the benchmark data, the RX 580's Passmark G3D score is 8813, and its overall average benchmark score is 13559. This places it at the 53rd percentile of all GPUs, which is a modest standing. Its nearest rivals include the NVIDIA GeForce GTX 570 with an average score of 13564 (a 0% delta), the GTX 950 at 13549 (0.1% delta), and the AMD Radeon Pro 455 at 13416 (1.1% delta). These comparisons show that the RX 580 is essentially on par with older or lower-tier NVIDIA cards, which is consistent with the frame rates observed in Doom. The card's DirectX 12 Passmark score of 43 and Vulkan score of 45173 (from Geekbench) indicate that while it supports modern APIs, its execution throughput is limited.

The VRAM amount of 8 GB is not the issue at 4K in Doom, as the frame rate drops are more attributable to compute and fill rate limitations. The memory bandwidth of 256.0 GB/s is the same figure as the texture rate, suggesting a balanced but constrained design. At 1080p, the card delivers playable results — 90.4 FPS at Medium and 74.4 FPS at High — which aligns with its 53rd percentile ranking. However, the 4K results, with a maximum of 36.3 FPS at Low, demonstrate that the RX 580's GCN 4.0 architecture, despite its 14 nm process node, cannot handle the workload of Doom at that resolution. The card's TDP of 185 W and dual-slot design are typical for its era, but the performance data shows it is firmly outclassed by modern requirements.

CPU Role

The AMD Ryzen 7 7700 is a high-end desktop processor that is not the bottleneck in this configuration. With 8 cores and 16 threads, it offers substantial parallel processing capability, and its Zen 4 architecture, codenamed Raphael, is built on a 5 nm process by TSMC. The CPU's base clock is 3.80 GHz with a boost clock of 5.30 GHz, and it has a 65 W TDP, which is remarkably efficient for the performance it delivers. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3, providing ample fast memory for game logic and physics.

Benchmark scores for the Ryzen 7 7700 are strong. In Cinebench R23, it scores 29302 in multicore and 4136 in single-core, while in 3dmark, it achieves 8484 with 16 threads and 1049 with a single thread. Its Passmark multithread score is 34470, and it reaches 4063 in Passmark single-thread. These numbers place it at the 91st percentile of all CPUs, with an average benchmark score of 40468. Its nearest rivals include the AMD Ryzen 9 7940H at 40431 (0.1% delta), the AMD Ryzen AI 9 365 at 40262 (0.5% delta), and the Intel Core i9-13905H at 40712 (-0.6% delta). This shows the 7700 is competitive with mobile flagship parts, though slightly behind the Intel offering.

In Doom, the CPU's role is to feed the GPU with draw calls and handle game simulation. Given that the frame rates drop dramatically from 1080p to 4K — from 103 FPS at 1080p Low to 36.3 FPS at 4K Low — the data indicates that the GPU is saturated well before the CPU reaches its limits. The CPU's single-thread performance, as measured by the 3dmark single-thread score of 1049 and Cinebench R23 single-core score of 4136, is more than sufficient for Doom's engine, which was released in 2016 and is optimized for modern processors. The Ryzen 7 7700's memory support for DDR5 with a bandwidth of 83.2 GB/s also ensures that data can be fed to the GPU without stalling. The conclusion is that the CPU provides a stable foundation, but the RX 580's 53rd percentile ranking means the graphics card dictates overall performance.

How This Combo Ranks

The AMD Ryzen 7 7700 and AMD Radeon RX 580 combination ranks 1557 out of 1681 tested combos in Doom, placing it in the bottom 7.4% of all configurations. This low ranking is almost entirely attributable to the GPU, as the CPU is in the top 9% of processors. The RX 580's average benchmark score of 13559 is modest, and its 53rd percentile standing among GPUs means it is outclassed by most modern graphics cards. The nearest rival GPU, the GTX 570, scores nearly identically, which puts this combo in the same performance tier as systems built around graphics cards from 2010.

The ranking reflects the measured FPS data: at 1080p Ultra, the combo achieves 61.5 FPS, which is playable but not exceptional, and at 1440p Ultra, it drops to 39.9 FPS. The 4K results are all below 36.3 FPS, even at Low settings, which is a significant handicap. The CPU's strong performance — 29302 in Cinebench R23 multicore and 4136 in single-core — cannot compensate for the GPU's limitations in a graphically demanding title like Doom. The data suggests that while the Ryzen 7 7700 is a future-proof component, the RX 580 holds this pairing back, resulting in a ranking that is near the bottom of the database. For users seeking higher frame rates, upgrading the GPU would yield far more benefit than upgrading the CPU, given the latter's already high percentile ranking.
