Doom

The AMD Ryzen 7 3700X and Intel Arc B580 pairing delivers a smooth 1080p experience in Doom, but the data reveals a clear shift in system bottleneck as resolution and settings scale upward. At 1080p Low, the combo hits 186 FPS, while 4K Ultra drops to 39 FPS, illustrating how the Arc B580’s graphics workload becomes the dominant constraint at higher resolutions.

Resolution Scaling

The measured FPS data shows a steep decline as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate falls from 137 FPS at 1080p to 88 FPS at 1440p, then to 48 FPS at 4K. That represents a 35.8% drop from 1080p to 1440p, and a further 45.5% drop from 1440p to 4K. The scaling pattern indicates that the GPU is the primary limiting factor at higher resolutions, as the pixel throughput requirements outpace the Arc B580’s 13.67 TFLOPS FP32 compute capability.

The Low settings preset shows a similar trajectory, with 186 FPS at 1080p falling to 120 FPS at 1440p and 65 FPS at 4K. Interestingly, the percentage drop from 1080p to 1440p under Low settings (35.5%) nearly matches the High settings drop, suggesting that even at reduced graphical complexity, the resolution burden remains consistent. At Medium settings, the average FPS values are 162 (1080p), 105 (1440p), and 57 (4K), with the 4K result showing a minimum of 48 FPS and maximum of 65 FPS.

Ultra settings produce the most dramatic scaling penalty, with 112 FPS at 1080p, 72 FPS at 1440p, and just 39 FPS at 4K. The gap between 1440p and 4K under Ultra (a 45.8% reduction) is nearly identical to the High settings drop, reinforcing that the resolution scaling is consistent regardless of quality preset. The data suggests that 1080p is the sweet spot for this combination, while 4K Ultra is only playable for users tolerant of sub-40 FPS frame rates.

GPU Role

The Intel Arc B580, built on the Xe2-HPG architecture with the BMG-G21 chip, carries 12 GB of GDDR6 memory on a 192-bit bus, yielding 456.0 GB/s of bandwidth. The GPU operates at a base and boost clock of 2670 MHz, with memory clocked at 2375 MHz (19 Gbps effective). With 2560 shading units, 160 TMUs, and 80 ROPs, the card delivers a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s.

In Doom, the GPU’s memory capacity and bandwidth play a notable role at 4K. The 12 GB frame buffer is sufficient for the game’s textures at all settings, but the bandwidth constraint becomes evident in the scaling data. At 4K Ultra, the 39 FPS average suggests the card is compute-bound rather than memory-bound, as the 13.67 TFLOPS FP32 throughput struggles to maintain higher frame rates. The 190 W TDP and dual-slot design indicate the card is operating within its thermal envelope, though the 450 W suggested PSU provides headroom for the rest of the system.

The GPU’s benchmark scores place it in the 68th percentile of all GPUs, with an average benchmark score of 23021. Its nearest rival, the AMD Radeon RX 580 2048SP, scores 23061, a delta of -0.2%, indicating near-identical synthetic performance. The NVIDIA GeForce RTX 2080 scores 22895 (0.6% delta), while the RTX 3080 scores 23172 (-0.7% delta), showing that the Arc B580 sits in a competitive band with these older and newer NVIDIA offerings respectively. In Doom specifically, the measured FPS at 1080p High (137 FPS) aligns with the card’s mid-range positioning, though the 4K results trail expectations for a GPU with 12 GB of VRAM.

CPU Role

The AMD Ryzen 7 3700X provides 8 cores and 16 threads based on the Zen 2 (Matisse) architecture, fabricated on TSMC’s 7 nm process. The CPU runs at a base clock of 3.60 GHz and boosts to 4.40 GHz, with a 65 W TDP. Its 32 MB L3 cache and 51.2 GB/s dual-channel DDR4 memory bandwidth are adequate for feeding the Arc B580, particularly at 1080p where the CPU’s performance ceiling is more likely to be tested.

The 3700X’s benchmark scores show strong multi-threaded capability, with a Cinebench R15 multicore score of 2092 and a Geekbench multicore score of 8899. Single-thread performance is comparatively modest, with a Cinebench R15 single-core score of 204 and Geekbench single-core score of 1593. In Doom, a game that relies heavily on single-thread performance for game logic and physics, this creates a potential bottleneck at high frame rates.

At 1080p Low, the 186 FPS average indicates the CPU is keeping pace with the GPU’s output, but the 137 FPS at 1080p High and 112 FPS at Ultra suggest the CPU is not the limiting factor in these scenarios. The PassMark multithread score of 22458 and single-thread score of 2656 place the 3700X in the 84th percentile of all CPUs, with an average benchmark score of 34260. Its nearest rivals include the AMD Ryzen AI 7 350 (34222, 0.1% delta) and the Intel Core i5-13450HX (34333, -0.2% delta), showing the 3700X remains competitive despite its age.

The CPU’s role becomes more critical at 1080p where the GPU has excess capacity. The measured FPS spread from 112 (Ultra) to 186 (Low) at 1080p indicates the CPU can deliver high frame rates, but the game’s engine may not fully utilize all 8 cores, leaving single-thread performance as a potential ceiling. At 1440p and 4K, the CPU’s workload diminishes relative to the GPU, and the data shows the GPU becomes the clear bottleneck.

Measured FPS Breakdown

At 1920x1080, the combo delivers playable frame rates across all settings. Low settings average 186 FPS, Medium 162 FPS (with a minimum of 137 FPS and maximum of 186 FPS), High 137 FPS, and Ultra 112 FPS. The spread from Low to Ultra is 74 FPS, representing a 39.8% performance penalty for maximum visual quality. These numbers indicate that 1080p gaming is smooth even at Ultra, with no risk of dropping below 100 FPS.

Moving to 2560x1440, the average frame rates decrease proportionally. Low settings average 120 FPS, Medium 105 FPS (minimum 89 FPS, maximum 120 FPS), High 88 FPS, and Ultra 72 FPS. The 1440p results remain playable, with only Ultra dipping below the 75 FPS threshold that competitive players might prefer. The gap between Low and Ultra at 1440p is 48 FPS, a 40% reduction, consistent with the 1080p scaling.

At 3840x2160, the performance drops significantly. Low settings average 65 FPS, Medium 57 FPS (minimum 48 FPS, maximum 65 FPS), High 48 FPS, and Ultra 39 FPS. The 4K results show that only Low settings achieve a consistently smooth experience, while Ultra falls below 40 FPS. The minimum FPS at 4K Medium (48 FPS) matches the average FPS at 4K High, indicating frame pacing consistency. The data shows that 4K gaming is possible but requires sacrificing quality presets to maintain playability.

How This Combo Ranks

The AMD Ryzen 7 3700X and Intel Arc B580 combination ranks 2786 out of 3712 tested combos in Doom, placing it in the 25th percentile of all configurations. This ranking reflects the mid-range positioning of both components, with the CPU’s 84th percentile standing offset by the GPU’s 68th percentile. The combo rank suggests that while the individual components are capable, the pairing does not push into the upper echelon of Doom performance.

The ranking is influenced by the CPU’s single-thread performance, which lags newer processors. The 3700X’s Cinebench R15 single-core score of 204 is modest compared to its multicore score of 2092, and this imbalance shows in a game like Doom where single-thread performance is critical. The GPU’s 68th percentile ranking also caps the combo’s potential, as the Arc B580’s 13.67 TFLOPS FP32 throughput limits high-resolution performance.

Relative to other combos, this pairing sits in the lower third of tested configurations. The GPU’s nearest rivals, including the RTX 2080 and RTX 3080, are typically paired with stronger CPUs in higher-performing combos, which pushes the 3700X+B580 down the rankings. The data indicates that users seeking higher combo ranks would benefit from a stronger CPU with better single-thread performance, or a higher-tier GPU, but the current pairing remains viable for 1080p and 1440p gaming.
