# Overpower with AMD Ryzen 5 8400F + AMD Radeon RX 6600

The AMD Ryzen 5 8400F paired with the AMD Radeon RX 6600 delivers a mid-range desktop experience for the 2023 action title Overpower, with measured frame rates spanning from 44 FPS at 4K Ultra to 119.4 FPS at 1080p Low. The combination ranks 1401st out of 1744 tested configurations in this game, placing it in the lower half of the field, which suggests that while the system is playable at lower resolutions and settings, it struggles to maintain high frame rates at the most demanding presets. The data set provides a clear picture of how this CPU-GPU pairing behaves across three resolutions and four quality settings, offering a methodical view of its strengths and limitations.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor built on the Zen 4 architecture with a Phoenix codename, manufactured on a 4 nm process by TSMC. It operates at a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP and support for DDR5 memory on the AMD Socket AM5 platform. The CPU's cache structure includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 16 MB of L3 cache, while its dual-channel memory bus provides 83.2 GB/s of bandwidth. Benchmark results show a single-thread score of 951 in 3dmark and a multi-thread score of 6165 in 3dmark_max_threads, along with a Cinebench R23 multi-core score of 20851 and a single-core score of 2943.

In Overpower, the CPU's role appears secondary to the GPU, as frame rates scale more dramatically with resolution changes than with core load variations. The processor's percentile rank of 82 among all CPUs indicates it sits above average, and its nearest rivals include the AMD Ryzen 7 2700X with a deltaPct of 0, the AMD Ryzen AI 5 PRO 340 at -0.1, the AMD EPYC 9474F at -0.2, and the AMD Ryzen 5 7500F at 0.3. These rivals are all within a fraction of a percent in average benchmark score, suggesting the 8400F's compute performance is well-balanced for its class. The 12 threads handle the game's action-oriented workload without appearing to bottleneck the RX 6600, as evidenced by the relatively consistent frame rate drops from 1080p to 1440p and 4K that follow a GPU-bound pattern rather than a CPU-limited one.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with the Navi 23 chip, manufactured on a 7 nm process by TSMC, featuring 1792 shading units, 112 texture mapping units, and 64 raster operations pipelines. It includes 28 ray tracing cores and operates at a base clock of 1626 MHz with a boost clock of 2491 MHz and a game clock of 2044 MHz. The GPU comes with 8 GB of GDDR6 memory on a 128-bit bus, delivering 224.0 GB/s of bandwidth, and its 132 W TDP is complemented by a suggested 300 W power supply. The card's FP32 performance is rated at 8.928 TFLOPS, with a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s.

The RX 6600's percentile rank of 69 among all GPUs places it in the upper-mid range, and its nearest rivals include the AMD Radeon 890M with a deltaPct of 0, the AMD Radeon RX 580 2048SP at -0.2, the AMD Radeon RX 6700M at 0.2, and the NVIDIA GeForce RTX 3060 Ti at 0.5. In Overpower, the GPU's 8 GB VRAM is sufficient at 1080p and 1440p across all settings, but the measured frame rates at 4K reveal a clear limitation. The gap between Low (90.4 FPS) and Ultra (44 FPS) at 4K is substantial, indicating that the GPU's compute and memory bandwidth become increasingly strained as texture detail and effects scale up. The 128-bit memory bus and 224.0 GB/s bandwidth appear to be the constraining factors at higher resolutions, where the demand for memory throughput grows exponentially.

Resolution Scaling

The measured FPS data shows a consistent pattern of frame rate degradation as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate drops from 66.6 FPS at 1080p to 64 FPS at 1440p, a modest decrease of 2.6 FPS, but then falls to 50 FPS at 4K, representing a 21.9% reduction from the 1440p figure. At Low settings, the scaling is more pronounced: 119.4 FPS at 1080p drops to 108 FPS at 1440p (a 9.5% decrease) and then to 90.4 FPS at 4K (a 16.3% decrease from 1440p). The Medium preset shows a similar trend, with 74.7 FPS at 1080p, 67.2 FPS at 1440p, and 57.1 FPS at 4K.

These numbers indicate that the limiting component shifts from the GPU at 1080p to a more balanced constraint at 1440p, and then to a clearly GPU-bound scenario at 4K. The relatively small difference between 1080p and 1440p at High settings (66.6 vs 64 FPS) suggests that the CPU can keep up with the GPU's output at these resolutions, but the larger drop at 4K points to the RX 6600's memory bandwidth and shading capacity as the primary bottleneck. The Ultra preset amplifies this effect, with frame rates falling from 54.6 FPS at 1080p to 51.4 FPS at 1440p and then to 44 FPS at 4K, a cumulative reduction of 19.4% across the full resolution range.

FAQ

*Q: How does this system rank among all tested configurations for Overpower?*

A: The combination ranks 1401st out of 1744 total configurations, placing it in the lower 20% of tested systems. This ranking reflects the RX 6600's modest performance relative to higher-end GPUs in the benchmark database.

Q: Is the CPU or GPU more responsible for the frame rate differences between presets?

A: The data indicates the GPU is the primary driver of performance variation, as the frame rate differences between Low and Ultra at each resolution (e.g., 119.4 vs 54.6 at 1080p) are far larger than the differences attributable to CPU load. The CPU's high percentile rank of 82 supports this interpretation.

Settings Recommendations

Based on the measured FPS rows, the Medium preset at 1920x1080 offers the most balanced experience, delivering 74.7 FPS while retaining a reasonable level of visual quality. At 1440p, the Medium preset achieves 67.2 FPS, which is playable for action titles, while the High preset drops to 64 FPS. For players prioritizing smoothness over fidelity, the Low preset at 1080p provides the highest measured frame rate of 119.4 FPS, but the visual trade-off may be significant. The Ultra preset is not recommended at any resolution, as it consistently produces the lowest frame rates: 54.6 FPS at 1080p, 51.4 FPS at 1440p, and 44 FPS at 4K, all of which fall below the 60 FPS threshold commonly associated with responsive gameplay.

At 4K, the only viable option is the Low preset at 90.4 FPS, but the visual degradation likely outweighs the benefit of resolution. The High preset at 4K (50 FPS) and Medium at 4K (57.1 FPS) struggle to maintain fluid motion, making 1440p the highest resolution worth considering for this configuration.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are: Low at 119.4 FPS, Medium at 74.7 FPS, High at 66.6 FPS, and Ultra at 54.6 FPS. The gap between Low and Medium is 44.7 FPS, while the gap between Medium and High is 8.1 FPS, and the gap between High and Ultra is 12 FPS. This pattern shows diminishing returns as settings increase, with the largest performance cost occurring between Low and Medium.

At 2560x1440, the frame rates are: Low at 108 FPS, Medium at 67.2 FPS, High at 64 FPS, and Ultra at 51.4 FPS. The difference between Low and Medium is 40.8 FPS, while the difference between Medium and High is only 3.2 FPS, and the difference between High and Ultra is 12.6 FPS. This indicates that the Medium to High transition is relatively inexpensive, while the High to Ultra jump is more demanding.

At 3840x2160, the frame rates are: Low at 90.4 FPS, Medium at 57.1 FPS, High at 50 FPS, and Ultra at 44 FPS. The Low to Medium drop is 33.3 FPS, the Medium to High drop is 7.1 FPS, and the High to Ultra drop is 6 FPS. Across all resolutions, the Low preset consistently provides the highest frame rates, while the Ultra preset always yields the lowest, with the 4K Ultra figure of 44 FPS representing the weakest measured performance in the entire data set.
