Overpower

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 4090 delivers exceptional frame rates across all tested configurations in Overpower, making it one of the most capable combinations in the database. The data shows that the Ultra preset at 1440p and 4K remains fully playable, while the High preset offers a balanced experience that maximizes visual fidelity without sacrificing smoothness. The Medium preset provides the widest headroom for demanding scenes, with minimum frame rates that keep the action fluid.

Settings Recommendations

The benchmark results indicate that the High preset is the optimal choice for this combination. At 1920x1080, the High preset delivers 173 FPS on average, which is only 14 FPS below the Medium preset's 187 FPS average, but the visual improvements are substantial. Moving to 2560x1440, High still maintains 155 FPS average, remaining comfortably above the 144 Hz refresh rate threshold that many high-end displays use. At 3840x2160, the High preset achieves 131 FPS average, which is still excellent for 4K gaming.

The Ultra preset is the most demanding option tested, and while it produces lower frame rates, the results remain playable across all resolutions. At 1080p, Ultra yields 144 FPS average; at 1440p, it drops to 128 FPS; and at 4K, it settles at 109 FPS. These figures confirm that even the most graphically intensive settings are viable with this hardware, though the gap between Ultra and High narrows as resolution increases, suggesting that the GPU becomes the primary constraint at higher pixel counts.

For competitive play, the Low preset offers the highest possible frame rates, reaching 244 FPS at 1080p, 235 FPS at 1440p, and 223 FPS at 4K. These numbers indicate that the combination can push well beyond 200 FPS even at 4K when visual fidelity is sacrificed. The Medium preset provides a middle ground, with minimum frame rates recorded at 159 FPS at 1080p, 142 FPS at 1440p, and 120 FPS at 4K, ensuring that even the most chaotic scenes remain fluid.

GPU Role

The NVIDIA GeForce RTX 4090 is the dominant component in this pairing, and its role becomes increasingly apparent as resolution scales upward. The GPU's 24 GB of GDDR6X memory across a 384-bit bus provides 1.01 TB/s of bandwidth, which is more than sufficient for Overpower's texture and geometry demands at any resolution. The memory clock runs at 1313 MHz, translating to 21 Gbps effective, and the GPU's base clock of 2235 MHz boosts to 2520 MHz under load.

The RTX 4090's raw compute capabilities are substantial, with 16,384 shading units, 512 texture mapping units, and 176 render output units. The GPU achieves a pixel rate of 443.5 GPixel/s and a texture rate of 1,290.2 GTexel/s, with FP32 performance rated at 82.58 TFLOPS. These specifications explain why the GPU can maintain high frame rates even at 4K resolution, where pixel throughput becomes critical.

The benchmark data confirms that the GPU is the limiting factor at higher resolutions. From 1080p to 1440p, the High preset drops from 173 FPS to 155 FPS, an 18 FPS reduction. From 1440p to 4K, the same preset falls from 155 FPS to 131 FPS, another 24 FPS reduction. This consistent scaling pattern indicates that the GPU's rendering capacity is being taxed progressively as pixel count increases, while the CPU remains capable of feeding the GPU with enough data to avoid becoming the bottleneck.

How This Combo Ranks

This combination ranks 132nd out of 3,713 tested combos in Overpower, placing it in the top 3.6% of all configurations in the database. This high ranking is driven primarily by the RTX 4090's exceptional rasterization performance, as the CPU's synthetic scores are modest relative to its GPU counterpart.

The ranking reflects the balance between the two components. While the Ryzen 5 8400F is not a flagship CPU, its 6 cores and 12 threads running at 4.20 GHz base and 4.70 GHz boost provide sufficient throughput to avoid bottlenecking the RTX 4090 in most scenarios. The data shows that the combination maintains high frame rates even at lower resolutions where CPU overhead would typically be more significant.

The combo's position in the 132nd spot suggests that there are 131 combinations that outperform it, likely featuring higher-tier CPUs paired with the same or similar GPUs. However, the margin between this combo and those above it is likely small, given the RTX 4090's dominance in the GPU hierarchy.

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. The CPU operates at a base clock of 4.20 GHz and boosts to 4.70 GHz, with a 65 W TDP. The processor features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache.

In Overpower, the CPU's role is to feed the RTX 4090 with draw calls and game logic. The benchmark results show that the CPU is not the primary bottleneck at any resolution. At 1080p with Low settings, the combination reaches 244 FPS, which is the highest frame rate recorded in the dataset. This indicates that the CPU can handle the game's single-threaded and multi-threaded demands even at very high frame rates.

The CPU's synthetic benchmark scores provide context for its performance. In Cinebench R23, the processor scores 20,851 in multi-core and 2,943 in single-core. The 3DMark scores show scaling from 1,874 in 2-thread tests to 6,165 in max-thread tests, indicating good multi-threading efficiency. The Passmark multi-thread score of 24,389 and single-thread score of 3,685 further confirm the CPU's balanced capabilities.

The CPU's memory bandwidth of 83.2 GB/s via dual-channel DDR5 support is adequate for the game's data streaming requirements, though it is substantially lower than the GPU's 1.01 TB/s bandwidth. This disparity is expected, as the CPU and GPU serve different roles in the rendering pipeline.

The Low preset achieves 223 FPS, the Medium preset reaches 142 FPS with a minimum of 120 FPS and a maximum of 163 FPS, the High preset produces 131 FPS, and the Ultra preset yields 109 FPS. The spread from Low to Ultra is 114 FPS, indicating that the GPU's workload increases more sharply at 4K.

The Medium preset is the only configuration with recorded minimum and maximum frame rates, providing insight into frame time consistency. At 1080p, the minimum of 159 FPS and maximum of 215 FPS show a 56 FPS range. At 1440p, the range narrows to 50 FPS (142 to 192). At 4K, the range is 43 FPS (120 to 163). This tightening range at higher resolutions suggests that frame pacing becomes more consistent as the GPU becomes the limiting factor.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals important information about the limiting component at each resolution. For the Low preset, the frame rate drops from 244 FPS at 1080p to 235 FPS at 1440p (a 3.7% reduction) and then to 223 FPS at 4K (a 5.1% reduction from 1440p). This relatively modest scaling suggests that the CPU is the primary constraint at low settings, as the GPU has ample headroom to render even at 4K.

For the Medium preset, the frame rate drops from 187 FPS at 1080p to 167 FPS at 1440p (a 10.7% reduction) and then to 142 FPS at 4K (a 15.0% reduction from 1440p). The increasing percentage drops indicate that the GPU is becoming more involved as settings increase, but the CPU still contributes to the overall performance.

The High preset shows similar scaling: 173 FPS at 1080p drops to 155 FPS at 1440p (a 10.4% reduction) and then to 131 FPS at 4K (a 15.5% reduction from 1440p). The Ultra preset follows the same pattern, with 144 FPS at 1080p dropping to 128 FPS at 1440p (an 11.1% reduction) and then to 109 FPS at 4K (a 14.8% reduction from 1440p).

The data reveals that the GPU becomes the dominant limiting factor at higher settings and resolutions. The percentage drops from 1080p to 4K increase from 8.6% for Low (244 to 223 FPS) to 24.3% for Ultra (144 to 109 FPS). This widening gap indicates that the RTX 4090's rendering workload scales significantly with resolution and settings, while the CPU's contribution remains relatively constant across all configurations.
