Overpower

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

The measured data for Overpower shows a clear pattern of GPU-bound scaling as resolution increases. At Low settings, the frame rate drops from 122.7 FPS at 1920x1080 to 107.9 FPS at 2560x1440, then further to 93.3 FPS at 3840x2160. That represents a 24% reduction from 1080p to 4K, which is a relatively modest drop for a 4X pixel count increase. This indicates that at Low settings, the Intel Core i5-13400F and Intel Arc B580 combination is still somewhat CPU-limited even at higher resolutions, as the frame rate does not scale down proportionally with the pixel workload.

The picture changes dramatically at Ultra settings. Here, the average FPS falls from 61.0 at 1080p to 50.7 at 1440p, and then to 48.0 at 4K. The total drop from 1080p to 4K is only 21.3%, which is even smaller than the Low settings drop. This is a strong signal that the graphics card is fully saturated at Ultra settings across all resolutions, and the bottleneck shifts almost entirely to the GPU's rendering capabilities rather than the CPU's ability to feed frames.

At Medium settings, the scaling pattern is more conventional: 74.4 FPS at 1080p, 70.5 FPS at 1440p, and 61.7 FPS at 4K. The 1080p-to-4K reduction of 17.1% sits between the Low and Ultra extremes. High settings show a similar trend: 73.5 FPS at 1080p, 67.2 FPS at 1440p, and 53.3 FPS at 4K, a 27.5% reduction. The High setting at 4K lands at 53.3 FPS, which is just above the 48.0 FPS Ultra result, suggesting that the GPU's raw throughput is the limiting factor.

The key takeaway from the resolution scaling data is that this combo behaves differently depending on the preset. At Low and Medium, the performance gap between 1080p and 4K is compressed, meaning the CPU or some other system component is preventing the GPU from being fully utilized. At High and Ultra, the GPU is clearly the bottleneck, as evidenced by the smaller absolute FPS differences between resolutions. The data indicates that players targeting 4K should stick to Medium or High settings to stay above 60 FPS, while 1080p and 1440p players have more headroom.

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

The Intel Core i5-13400F is a 10-core, 16-thread processor based on Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. It features a 20 MB shared L3 cache and supports dual-channel DDR4 or DDR5 memory. The CPU's benchmark scores place it in the 82nd percentile among all tested CPUs, with an average benchmark score of 25236. Its nearest rival, the Intel Core i7-13620H, scores 25201, a delta of just 0.1% — essentially identical performance.

In Overpower, the CPU's role is most evident at lower settings and lower resolutions. At 1080p Low, the combo achieves 122.7 FPS, which is the highest measured result across all configurations. The fact that this drops only to 93.3 FPS at 4K Low (a 24% reduction) suggests that the CPU is capable of sustaining high frame rates, but the GPU begins to take over as the primary limiter at higher resolutions. The i5-13400F's 10 cores and 16 threads provide ample parallel processing for modern action games, and its single-thread performance (3dmark single-thread score of 960) is strong enough to avoid becoming a bottleneck at 1080p.

The CPU's multi-threaded capabilities are also relevant. The 3dmark 16-thread score of 7314 and max-threads score of 7307 indicate that the processor scales well with additional threads, which helps in games that utilize multiple cores for physics, AI, and world streaming. The Cinebench R23 multi-core score of 21279 further confirms this. However, the fact that Overpower's frame rates do not improve dramatically when moving from 1440p to 4K at High settings (67.2 to 53.3 FPS) indicates that the GPU is the limiting component in most realistic gaming scenarios.

Compared to its nearest rivals, the i5-13400F is statistically tied with the AMD Ryzen 5 5600X3D (delta -0.5%) and the AMD EPYC 9474F (delta 0.5%). This means that for Overpower, the CPU is not a differentiator — the GPU choice matters far more. The data shows that the i5-13400F provides enough headroom to push the Arc B580 to its limits at 1080p and 1440p, but at 4K, no amount of CPU power can overcome the GPU's rendering ceiling.

How This Combo Ranks

The Intel Core i5-13400F + Intel Arc B580 combination ranks 1363 out of 1744 tested combos in Overpower. This places it in the bottom 22% of all configurations tested, which may seem surprising given the individual component scores. However, the ranking reflects the fact that Overpower appears to be a demanding title at higher settings, and this mid-range GPU/CPU pairing is not designed to compete with top-tier hardware.

The CPU itself ranks in the 82nd percentile among all CPUs, meaning it is better than 82% of tested processors. The GPU, however, ranks in the 66th percentile among all GPUs, which is more modest. The combo's overall rank of 1363/1744 suggests that the GPU is the limiting factor for this pairing's overall standing. The data shows that the combo performs best at 1080p and 1440p with Medium or High settings, where it can maintain frame rates above 70 FPS. At 4K, it falls below 60 FPS at all settings except Low.

Compared to other combos, the Arc B580's nearest rival is the AMD Radeon 760M (delta 0.1%) and the NVIDIA P106-100 (delta 0.3%), both of which are integrated or older discrete solutions. The RTX 4060 is 0.7% faster on average, which would likely translate to slightly higher frame rates in Overpower, but the differences are small enough that the i5-13400F + Arc B580 remains a competitive mid-range option.

Settings Recommendations

Based on the measured FPS data, the best experience for this combo depends on the target resolution. At 1920x1080, Medium settings deliver 74.4 FPS, which is ideal for smooth gameplay, while High settings only drop to 73.5 FPS — essentially identical. Ultra at 1080p yields 61.0 FPS, which is still playable but sacrifices 13.4 FPS compared to Medium. The data suggests that High settings at 1080p offer the best balance of visual quality and performance, as the 1.2% difference between Medium and High is negligible.

At 2560x1440, Medium delivers 70.5 FPS, which is the sweet spot. High settings drop to 67.2 FPS, a 4.7% reduction that may be worth it for improved visuals. Ultra at 1440p falls to 50.7 FPS, which is below the 60 FPS threshold and not recommended for competitive play. Low settings at 1440p reach 107.9 FPS, but the visual compromise is likely too severe for most players.

At 3840x2160, only Low (93.3 FPS) and Medium (61.7 FPS) are viable options. High settings at 4K produce 53.3 FPS, which is borderline playable, while Ultra drops to 48.0 FPS. For 4K gaming, Medium is the recommended preset, as it maintains 61.7 FPS while offering significantly better visuals than Low. The 4.6 FPS difference between Medium and High at 4K is not worth the visual upgrade, making Medium the clear choice.

The difference between Low and Medium at 4K is 31.6 FPS, while the difference between Medium and High is 8.4 FPS. The data shows that the GPU's performance scales nearly linearly with the quality preset at 4K, with each step up in settings costing roughly 12-15% performance. The full breakdown reveals that this combo is best suited for 1080p and 1440p gaming, with 4K reserved for Low or Medium settings.

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

The Intel Arc B580 is built on the Xe2-HPG architecture (Battlemage generation) with a 5 nm process from TSMC. It features 12 GB of GDDR6 memory on a 192-bit bus, delivering 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). It has 2560 shading units, 160 TMUs, and 80 ROPs, along with 20 ray tracing cores. The GPU's FP32 performance is 13.67 TFLOPS, and it offers a pixel rate of 213.6 GPixel/s.

The Arc B580's average benchmark score is 23021, placing it in the 66th percentile among all GPUs. Its nearest rival, the NVIDIA GeForce RTX 4060, scores 23181 (delta -0.7%), meaning the B580 is slightly behind but within noise. The GeForce RTX 4060 Mobile scores 22729 (delta 1.3%), and the AMD Radeon 760M scores 22999 (delta 0.1%). This places the B580 in the upper mid-range tier, capable of 1080p and 1440p gaming with high settings.

In Overpower, the GPU's 12 GB of VRAM is sufficient for all tested settings, even at 4K Ultra, where the game consumes more memory for high-resolution textures. The 456.0 GB/s bandwidth ensures that texture streaming does not become a bottleneck, as evidenced by the consistent frame rates across settings. The 2670 MHz clock speed, combined with the 13.67 TFLOPS FP32 throughput, allows the GPU to handle the game's action-heavy scenes with complex lighting and particle effects.

The data shows that the GPU is the primary limiter at High and Ultra settings across all resolutions. At 4K Ultra, the 48.0 FPS result is close to what would be expected from a GPU with this compute throughput. The fact that the B580 outperforms the RTX 4060 Mobile by 1.3% in average benchmark score, yet delivers lower frame rates in Overpower at 4K, suggests that the game may favor NVIDIA's architecture slightly, or that the B580's driver optimization is less mature. Regardless, the GPU's 66th percentile ranking indicates it is a capable performer for its class, and the measured FPS data confirms it can deliver smooth gameplay at 1080p and 1440p with the right settings.
