Overpower

The AMD Ryzen 5 8400F and AMD Radeon RX 7900 XTX combination delivers a high-refresh-rate 1440p and 4K experience in Overpower, with the GPU acting as the primary performance arbiter across all tested settings. The data shows a clear hierarchy: Ultra settings at 4K produce 92.1 FPS, while dropping to Low at 1080p reaches 244.1 FPS, indicating a system that scales predictably with both resolution and graphical load. This pairing ranks in the 87th percentile of all tested combos, placing it 213rd out of 1744 configurations.

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

The Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 (Phoenix) architecture, running on the AMD Socket AM5 platform. Its base clock is 4.20 GHz with a boost clock of 4.70 GHz, and it carries a 65 W TDP. The CPU’s cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache, which is a modest amount for feeding a flagship GPU.

Benchmark results place this CPU in the 82nd percentile of all processors, with an average benchmark score of 25064. Its nearest rivals provide context for its positioning: the AMD Ryzen 7 2700X scores 25057 (a 0% delta), the AMD Ryzen AI 5 PRO 340 scores 25099 (-0.1% delta), the AMD EPYC 9474F scores 25103 (-0.2% delta), and the AMD Ryzen 5 7500F scores 24993 (0.3% delta). This means the 8400F is essentially tied with these chips in synthetic multi-threaded workloads, showing that its 6-core/12-thread configuration is competitive but not exceptional.

In Overpower, the CPU’s role appears secondary to the GPU. At 1080p Low settings, the system achieves 244.1 FPS, which is the highest measured result. This suggests the processor can sustain very high frame rates when the graphics load is minimal. However, the scaling from 1080p Low to 4K Low (187.6 FPS) shows a 23% drop, indicating that even at low graphical settings, the resolution increase begins to shift the bottleneck toward the GPU. The 3DMark scores reinforce the CPU’s capability: 951 in single-thread, 1874 in 2-thread, 3563 in 4-thread, 5275 in 8-thread, and 6165 in max-thread tests. These figures suggest a processor that handles moderate thread counts well, which is sufficient for Overpower’s action gameplay, but the data does not show the CPU creating a notable ceiling at any resolution tested.

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

The Radeon RX 7900 XTX is the dominant component in this pairing, built on the RDNA 3.0 architecture with the Navi 31 chip. It features 24 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. The GPU’s base clock is 1929 MHz, with a game clock of 2365 MHz and a boost clock of 2498 MHz. Memory runs at 2500 MHz (20 Gbps effective). This configuration yields 6144 shading units, 384 TMUs, and 192 ROPs, with 96 ray-tracing cores.

The GPU ranks in the 85th percentile of all graphics cards, with an average benchmark score of 44019. Its nearest rivals show narrow margins: the AMD Radeon Pro 580 scores 44195 (-0.4% delta), the NVIDIA GeForce RTX 4090 Mobile scores 43667 (0.8% delta), the NVIDIA Quadro M6000 scores 43313 (1.6% delta), and the NVIDIA GeForce RTX 4070 Ti scores 44900 (-2% delta). This places the 7900 XTX in the same performance tier as these cards, though the data shows it slightly trailing the RTX 4070 Ti in average score.

In Overpower, the GPU’s impact is most visible at 4K resolution. At Ultra settings, the system produces 92.1 FPS, while at High settings it reaches 106.8 FPS, and at Medium 115.8 FPS. The 24 GB VRAM buffer ensures that memory capacity is not a limiting factor at any tested configuration, as even the highest settings do not show a disproportionate drop that would indicate VRAM pressure. The GPU’s FP32 performance of 61.39 TFLOPS and texture rate of 959.2 GTexel/s support the measured frame rates, with the system maintaining above 90 FPS even at the most demanding 4K Ultra preset.

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

The measured FPS data reveals a consistent scaling pattern that shifts from CPU-bound at low resolutions to GPU-bound at higher resolutions. At Low settings, the progression from 1080p (244.1 FPS) to 1440p (217.3 FPS) to 4K (187.6 FPS) shows a 11% drop from 1080p to 1440p and a 14% drop from 1440p to 4K. This relatively gentle decline indicates that at Low settings, the CPU and GPU are both contributing, but the frame rates remain high enough that the system is not severely constrained.

At Ultra settings, the scaling becomes steeper. From 1080p (120.4 FPS) to 1440p (104 FPS), there is a 14% drop, and from 1440p to 4K (92.1 FPS), another 11% drop. The total reduction from 1080p Ultra to 4K Ultra is 23.5%. This pattern suggests that as resolution increases, the GPU becomes the limiting component, with the CPU maintaining sufficient headroom to feed the graphics card even at 4K.

The Medium settings show a similar trend: 151.6 FPS at 1080p, 139.8 FPS at 1440p (8% drop), and 115.8 FPS at 4K (17% drop from 1440p). The High settings follow with 143.2 FPS at 1080p, 124.7 FPS at 1440p (13% drop), and 106.8 FPS at 4K (14% drop from 1440p). The data indicates that the GPU is the primary bottleneck at 4K for all settings, while at 1080p, the CPU still has room to push frame rates higher if the GPU were more powerful.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data is presented across three resolutions and four settings levels. At 1920x1080, the system achieves 244.1 FPS on Low, 151.6 FPS on Medium, 143.2 FPS on High, and 120.4 FPS on Ultra. The spread from Low to Ultra at 1080p is 123.7 FPS, showing a significant impact from graphical settings.

At 2560x1440, the results are 217.3 FPS on Low, 139.8 FPS on Medium, 124.7 FPS on High, and 104 FPS on Ultra. The difference between Low and Ultra at 1440p is 113.3 FPS, which is a slightly smaller gap than at 1080p, indicating the GPU is beginning to assert its role.

At 3840x2160, the system delivers 187.6 FPS on Low, 115.8 FPS on Medium, 106.8 FPS on High, and 92.1 FPS on Ultra. The Low-to-Ultra gap at 4K is 95.5 FPS, the smallest of the three resolutions, confirming that the GPU becomes the dominant constraint as pixel count increases.

Settings Recommendations — which preset gives the best experience per the measured rows

For players prioritizing the highest frame rates, Low settings at any resolution provide the best results, with 244.1 FPS at 1080p, 217.3 FPS at 1440p, and 187.6 FPS at 4K. These figures are all well above the threshold for competitive play, but the visual fidelity is compromised.

The Medium preset offers a more balanced experience. At 1080p, it delivers 151.6 FPS, which is 8.5% higher than High settings (143.2 FPS) and 20.6% higher than Ultra (120.4 FPS). At 1440p, Medium produces 139.8 FPS, which is 12.1% higher than High (124.7 FPS) and 34.4% higher than Ultra (104 FPS). At 4K, Medium achieves 115.8 FPS, outperforming High (106.8 FPS) by 8.4% and Ultra (92.1 FPS) by 25.7%.

The data suggests that Medium is the optimal preset for this combo. It maintains frame rates above 115 FPS at all resolutions while providing a meaningful visual upgrade over Low. High settings offer a marginal improvement in visual quality but come with a frame rate penalty of 8-12% compared to Medium, making it less desirable for players with 144Hz or 165Hz monitors. Ultra settings are only recommended for 4K displays where the 92.1 FPS result is still playable, but the performance cost is steep relative to the visual gains.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 5 8400F with AMD Radeon RX 7900 XTX ranks 213rd out of 1744 tested combos in Overpower. This places the configuration in the 87.8th percentile, meaning it outperforms the vast majority of systems tested. The rank reflects the GPU’s strong performance, given that the CPU sits in the 82nd percentile of all processors while the GPU is in the 85th percentile.

The ranking is consistent with the measured FPS data. The combo’s ability to exceed 90 FPS at 4K Ultra and 120 FPS at 1080p Ultra demonstrates hardware that is well-matched for high-end gaming. The CPU’s nearest rival, the Ryzen 5 7500F, has an average benchmark score that is 0.3% higher, but the 8400F’s 6-core/12-thread design provides ample performance for this title, as evidenced by the frame rates.

The GPU’s nearest rivals include the RTX 4070 Ti, which has a higher average score (44900 vs 44019), but the 7900 XTX’s 24 GB VRAM and 960 GB/s bandwidth give it an advantage in memory-intensive scenarios, which may explain its top-12% ranking in this specific game. Overall, the combo’s 213rd rank out of 1744 indicates it is a high-tier configuration, though not at the absolute top, with the data showing room for improvement if a more powerful CPU were paired with the 7900 XTX.
