Overpower

The AMD Ryzen 5 8400F pairs a 6-core, 12-thread Zen 4 design with a 4.20 GHz base and 4.70 GHz boost clock. This configuration places it in the 82nd percentile of all CPUs, with an average benchmark score of 25064. In synthetic tests, the chip demonstrates strong scaling from 1874 points in the 2-thread test to 6165 points at max threads, indicating that the 12 threads are effectively utilized. Its single-thread score of 951 in 3DMark is modest, but the multi-thread results are where the CPU shows its strength. The 8400F’s nearest rival, the AMD Ryzen 5 7500F, scores 24993, a negligible 0.3% difference, while the older AMD Ryzen 7 2700X matches it almost exactly at 25057 (0% delta). This suggests the 8400F offers a balanced throughput that is neither a bottleneck nor a standout performer in CPU-light scenarios.

In Overpower, an action title, the CPU’s role is evident when examining the frame rates at lower resolutions. At 1080p with Low settings, the combination achieves 211.7 FPS, which is the highest measured value across all configurations. This high frame rate indicates that the CPU is capable of feeding the GPU adequately at this level. However, the gap between Low and Ultra at 1080p is substantial: 211.7 FPS drops to 100.6 FPS. This 111.1 FPS delta is larger than the resolution scaling effect alone, pointing to the GPU becoming the primary limiter as settings increase. The 8400F’s 16 MB of shared L3 cache and dual-channel DDR5 memory support (with 83.2 GB/s bandwidth) provide sufficient headroom for the game’s data streaming, but the data does not show the CPU causing frame pacing issues. The 3DMark 16-thread score of 6091 and Cinebench R23 multi-core score of 20851 confirm that the processor has ample compute for the game’s physics and AI, which are typically expected in action titles. The CPU’s performance percentile of 82% versus all CPUs means it outperforms a majority of installed processors, ensuring that Overpower will not be CPU-bound at standard settings.

Settings Recommendations

The measured FPS data for Overpower reveals a clear hierarchy among the four presets, and the optimal choice depends on the display refresh rate. At 1080p, the High preset delivers 121.7 FPS, which is a solid 21 FPS improvement over Ultra’s 100.6 FPS. Medium offers 130.2 FPS, a further 8.5 FPS gain over High. Low settings produce 211.7 FPS, but this comes with significant visual compromises. For a standard 144Hz monitor, High is the best balance, as it exceeds the refresh threshold by 7.7 FPS while retaining higher visual fidelity than Medium. The data shows that Ultra at 1080p is the least efficient preset, as it only yields a 21.1 FPS advantage over Medium but likely incurs a large visual cost for that marginal gain. At 1440p, High delivers 110 FPS, which is still above a 100Hz refresh rate, while Medium sits at 118.1 FPS. The Ultra preset at 1440p drops to 89.6 FPS, which is below the 90 FPS threshold that many users consider a baseline for smooth gameplay. Therefore, at 1440p, High is again the recommended preset, as it provides a 20.4 FPS advantage over Ultra while maintaining a more consistent experience. At 4K, the situation changes drastically. High produces 94.5 FPS, while Medium is slightly better at 97.7 FPS. Ultra falls to 75.8 FPS, a 18.7 FPS drop from Medium. At this resolution, Medium is the best choice because it offers the highest FPS among the visual presets that are not Low (which hits 161.6 FPS but compromises fidelity). The data shows that the GPU is heavily taxed at 4K, and the difference between Medium and High is only 3.2 FPS, making Medium the more sensible option for maintaining a stable frame rate without sacrificing too much detail. Across all resolutions, the Low preset is only recommended for competitive play where maximum FPS (211.7 at 1080p) is prioritized over graphics.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a classic GPU-bound scenario in Overpower. At High settings, the transition from 1920x1080 (121.7 FPS) to 2560x1440 (110 FPS) is a modest 9.6% reduction. However, moving from 1440p to 3840x2160 (94.5 FPS) results in a 14.1% drop, totaling a 22.3% decrease from 1080p to 4K. This scaling pattern is not linear, indicating that the GPU’s pixel throughput becomes the limiting factor as resolution increases. The RTX 4070’s 12 GB of GDDR6X memory and 504.2 GB/s bandwidth are sufficient for the data load, but the 192-bit bus width and 64 ROPs constrain the fill rate at higher resolutions. At Low settings, the scaling is more pronounced: 211.7 FPS at 1080p drops to 190.2 FPS at 1440p (a 10.2% reduction) and then to 161.6 FPS at 4K (a 15.0% reduction from 1440p). This steeper decline at Low settings suggests that the CPU is still providing enough frames, but the GPU’s raw rasterization speed is overwhelmed by the pixel count. The Ultra preset shows the most severe scaling, with 100.6 FPS at 1080p falling to 89.6 FPS at 1440p (10.9% drop) and then to 75.8 FPS at 4K (15.4% drop). The 24.8 FPS difference between 1080p Ultra and 4K Ultra highlights that the RTX 4070, while capable at 1080p, loses over a quarter of its performance at 4K. This data indicates that the CPU is not the bottleneck; instead, the GPU’s compute units (5888 shading units) and memory subsystem are the primary constraints. The 29.15 TFLOPS FP32 performance is adequate for 1080p and 1440p, but the 4K results show that the card is stretched, as the average FPS at 4K High (94.5) is only 77.7% of the 1080p High figure.

Medium is recommended because it offers the highest FPS among the non-Low presets, and the 3.2 FPS difference from High is negligible for a 60Hz panel.

GPU Role

The NVIDIA GeForce RTX 4070 is the dominant component in this pairing, and its specifications directly correlate with the measured FPS in Overpower. The GPU features 5888 shading units, 184 texture mapping units, and 64 ROPs, with a boost clock of 2475 MHz. This configuration yields 29.15 TFLOPS of FP32 compute, which is substantial for a 200 W card. In the game, the GPU’s role is most apparent at higher resolutions and settings. At 1080p Low, the GPU is not fully utilized, as the CPU is able to push 211.7 FPS. However, at 4K Ultra, the GPU’s limitations become clear with 75.8 FPS. The 12 GB of GDDR6X memory on a 192-bit bus provides 504.2 GB/s of bandwidth, which is sufficient for the game’s textures at 4K, but the 64 ROPs are the bottleneck for pixel fill rate. The RTX 4070’s 3DMark Steel Nomad score of 3854 places it in the 81st percentile of all GPUs, with an average benchmark score of 37283. Its nearest rival, the AMD Radeon RX Vega 56, scores 37507, a -0.6% delta, indicating the 4070 is slightly slower in synthetic tests. However, the measured FPS in Overpower shows that the 4070 is well-suited for 1440p gaming, as it maintains 110 FPS at High settings. The GPU’s DirectX 12 passmark score of 103 and DirectX 11 score of 244 are low, but these are not indicative of real-world game performance. The 46 RT cores and 184 tensor cores are not directly tested in the measured FPS rows, but they suggest that ray tracing features, if enabled, would further impact frame rates. The GPU’s launch MSRP is 599 USD, and it is now end-of-life, with the GeForce 50 series as its successor. The data shows that the RTX 4070 is a capable 1440p card, but at 4K, the frame rates fall below the 100 FPS threshold for High and Medium presets, making it a marginal 4K option for this title.
