Overpower

The AMD Ryzen 5 8400F and Intel Arc B580 combination delivers a solid 1080p and 1440p experience in Overpower, but the data reveals a clear performance ceiling as resolution climbs. At 1080p High settings, the pair averages 72 FPS, which scales to 65 FPS at 1440p and drops further to 55 FPS at 4K. The frame rate curve is steep, indicating that the GPU becomes the dominant bottleneck at higher resolutions, while the CPU maintains a stable baseline across all tested configurations.

Resolution Scaling

The measured FPS data shows a predictable decline as resolution increases, but the rate of that decline tells a compelling story about system balance. Moving from 1080p to 1440p at High settings reduces average FPS from 72 to 65, a drop of approximately 10%. However, scaling from 1440p to 4K at High settings is more punishing, falling from 65 to 55 FPS, a 15% reduction. This steeper falloff at 4K suggests the Intel Arc B580’s 12 GB VRAM and 456.0 GB/s bandwidth are being pushed harder, while the CPU’s headroom is not the limiting factor.

At Ultra settings, the scaling pattern is even more pronounced. The combo manages 60 FPS at 1080p, 54 FPS at 1440p, and only 46 FPS at 4K. The 1080p-to-1440p transition costs 6 FPS, while the 1440p-to-4K transition costs 8 FPS, reinforcing that the GPU’s raw throughput is the primary constraint. Low settings provide the clearest view of the CPU’s capability: 125 FPS at 1080p, 111 FPS at 1440p, and 95 FPS at 4K. The relatively small gap between 1440p and 4K at Low settings (16 FPS) indicates that even at reduced graphical loads, the Arc B580 cannot fully saturate the Ryzen 5 8400F’s potential at higher resolutions.

Medium settings offer the only complete min/max data in the pack, showing 78 FPS average at 1080p (min 66, max 90), 70 FPS at 1440p (min 59, max 80), and 59 FPS at 4K (min 50, max 68). These ranges demonstrate consistent frame pacing without severe drops, suggesting the system handles moderate graphical loads without stuttering. Overall, the resolution scaling analysis points to a GPU-bound system: the 8400F has ample compute headroom, but the Arc B580’s performance degrades noticeably as pixel count increases.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Phoenix, built on TSMC’s 4 nm process. Its base clock of 4.20 GHz and boost clock of 4.70 GHz provide strong single-thread performance, which is critical for Overpower’s action gameplay. Benchmark scores support this: the CPU achieves 951 in 3DMark single-thread and 2943 in Cinebench R23 single-core, placing it in the 77th percentile versus all CPUs.

Multi-threaded performance is equally robust, with Cinebench R23 multicore scoring 20,851 and 3DMark max threads reaching 6,165. The 16 MB shared L3 cache and 83.2 GB/s dual-channel DDR5 memory bandwidth ensure the CPU can feed the GPU efficiently. In Overpower, the CPU’s role is evident from the Low settings results: at 1080p Low, the combo hits 125 FPS, and even at 4K Low it maintains 95 FPS. This indicates the 8400F is not the bottleneck, as frame rates remain high even when graphical load is minimized.

Compared to its nearest rivals, the 8400F’s average benchmark score of 25,005 is within 0.4% of the AMD Ryzen 5 7500F (24,964) and the Intel Core i7-13620H (24,911), while trailing the AMD EPYC 9474F (25,103) by 0.4%. These tight deltas suggest the 8400F is a competent mid-range CPU that holds its own against comparable chips. However, the 65W TDP and 4 nm process node are not directly reflected in gaming performance; rather, they indicate efficiency that allows sustained boost clocks during extended sessions.

GPU Role

The Intel Arc B580 is the clear driver of Overpower’s visual output, featuring 12 GB of GDDR6 memory on a 192-bit bus, delivering 456.0 GB/s bandwidth. Its Xe2-HPG architecture, built on TSMC’s 5 nm process, includes 2,560 shading units, 160 TMUs, and 80 ROPs, with a boost clock of 2670 MHz. The GPU’s 13.67 TFLOPS FP32 performance and 213.6 GPixel/s pixel rate are substantial, but the data shows they are insufficient for 4K Ultra, where the combo only manages 46 FPS.

The GPU’s percentile ranking of 68 versus all GPUs places it slightly below mid-tier, and its average benchmark score of 23,021 is remarkably close to rivals: the AMD Radeon RX 580 2048SP (23,061, -0.2% delta), NVIDIA GeForce RTX 2080 (22,895, +0.6% delta), and NVIDIA GeForce RTX 3080 (23,172, -0.7% delta). This clustering indicates the Arc B580 performs at a level comparable to older high-end cards, but its 12 GB VRAM and modern feature set give it an edge in texture-heavy scenes.

In Overpower, the GPU’s VRAM capacity becomes relevant at 4K, where High settings use more memory. The 55 FPS average at 4K High versus 46 FPS at 4K Ultra shows a 9 FPS penalty for the highest visual quality, suggesting memory bandwidth or shading unit limitations rather than VRAM exhaustion. The 2670 MHz boost clock is consistent across all scenarios, as the GPU’s thermal design (190W TDP) allows sustained performance without throttling.
