Overpower

Overpower’s measured frame rates for the Intel Core i5-10400F and AMD Radeon RX 7800 XT combination show a clear pattern: the GPU is the dominant factor at every resolution, with the CPU providing enough headroom to avoid becoming the bottleneck. The data indicates that scaling from 1080p to 4K is steep, but the RX 7800 XT’s 16 GB of VRAM and high clock speeds keep performance playable even at the most demanding settings.

Resolution Scaling

The FPS drops from 1080p to 4K are substantial, revealing a GPU-bound workload. At Low settings, the average frame rate falls from 165.7 FPS at 1920x1080 to 144.3 FPS at 3840x2160, a decline of roughly 13%. This modest decrease suggests that at Low settings, the system is still partially limited by the CPU’s single-thread performance, as the GPU has ample headroom to render frames quickly. However, the gap widens dramatically as settings increase. At High settings, the average drops from 112.6 FPS at 1080p to 83.4 FPS at 4K, a 26% reduction. At Ultra, the 1080p result of 91.9 FPS falls to 69 FPS at 4K, a 25% reduction. This consistent ~25% penalty from 1080p to 4K at higher presets points directly to the GPU’s pixel throughput limits.

The pattern is even clearer when comparing 1440p to 4K. At Medium settings, 1440p delivers 107 FPS, while 4K drops to 87.6 FPS. At High settings, 1440p yields 99.8 FPS versus 83.4 FPS at 4K. These differences of roughly 18% and 16%, respectively, indicate that the RX 7800 XT’s 256-bit memory bus and 624.1 GB/s bandwidth are being pushed hard at 4K. The 4K Ultra result of 69 FPS is the lowest measured value, and it sits just above the 60 FPS threshold, suggesting that the GPU’s 96 ROPs and 233.3 GPixel/s pixel rate are the limiting factors. The data shows that 1080p to 1440p scaling is relatively mild—only a 10-15% drop depending on settings—but the jump to 4K is where the GPU’s fill rate becomes the primary constraint.

GPU Role

The AMD Radeon RX 7800 XT is the clear performance driver in this combination. Its 16 GB of GDDR6 memory on a 256-bit bus provides 624.1 GB/s of bandwidth, which is critical for Overpower’s high-resolution textures. The clock speeds support this: a base of 1295 MHz, a game clock of 2124 MHz, and a boost of 2430 MHz. These clocks, combined with 3840 shading units and 60 RT cores, explain why the GPU maintains 83.4 FPS at 4K High. The 37.32 TFLOPS of FP32 compute is evidently sufficient for the game’s Action genre demands, as the 4K Medium result of 87.6 FPS shows only a 5% improvement over High, indicating diminishing returns from lowering settings.

The GPU’s 76th percentile ranking among all GPUs, with an average benchmark score of 32619, places it in a strong position. Its nearest rivals include the AMD FirePro S9300 X2 (32540, 0.2% ahead) and the NVIDIA P104-100 (32747, 0.4% behind), which are close matches. However, the RX 7800 XT’s 16 GB VRAM is a decisive advantage in Overpower, as the measured FPS at 4K Ultra (69 FPS) does not collapse despite the high texture load. The VRAM capacity ensures that the GPU does not spill into system memory, which would cause stuttering. The memory clock of 2438 MHz (19.5 Gbps effective) further supports this, as the game’s data streaming requirements are met without bandwidth throttling.

FAQ

Q: Does the RX 7800 XT bottleneck the Core i5-10400F in Overpower?

A: Yes, at higher settings. The 4K Ultra result of 69 FPS versus the 1080p Ultra result of 91.9 FPS shows a 25% drop, which is far larger than the CPU’s 6-core/12-thread configuration would cause. The GPU’s pixel rate and memory bandwidth are the limiting factors.

Q: What is the best resolution for this combo to maintain high FPS?

A: 1440p is the sweet spot. At High settings, it delivers 99.8 FPS, and at Medium, 107 FPS. Both are well above 60 FPS, and the 16 GB VRAM prevents texture pop-in at this resolution.

Q: How does the GPU perform relative to its closest rivals?

A: The RX 7800 XT’s average benchmark score of 32619 is 0.2% lower than the AMD FirePro S9300 X2 (32540) and 0.4% lower than the NVIDIA P104-100 (32747). In game, it holds a 76th percentile rank, meaning it outperforms 76% of all GPUs tested.

Q: Is the 4K Low setting viable for competitive play?

A: Yes, at 144.3 FPS average, 4K Low is highly viable. The frame rate is close to the 1080p Low result of 165.7 FPS, indicating that the GPU can handle 4K when visual effects are minimized.

Q: What is the CPU’s percentile ranking?

A: The Core i5-10400F ranks in the 73rd percentile among all CPUs, with an average benchmark score of 14168. Its nearest rival, the AMD EPYC 7552, scores 14115 (0.4% lower), while the Intel Core i5-8500 scores 14332 (1.1% higher).

Q: Does the CPU’s boost clock affect the 1080p results?

A: The 4.30 GHz boost clock likely helps the 1080p Low result of 165.7 FPS, as the GPU is not saturated at that resolution. The single-thread 3dmark score of 688 supports this, though the CPU’s 6 cores and 12 threads are more than adequate for the game’s threading model.

Settings Recommendations

The measured data points to Medium as the optimal preset for most users. At 1440p, Medium delivers 107 FPS, which is 7.2% higher than High (99.8 FPS) and 35.6% higher than Ultra (78.9 FPS). The jump from Medium to High at 1440p costs 7.2 FPS, which is negligible for visual fidelity gains, but the jump from High to Ultra costs 20.9 FPS, a much steeper penalty. At 4K, Medium (87.6 FPS) is the best balance, as it is 5% faster than High (83.4 FPS) and 27% faster than Ultra (69 FPS). For users with 1080p monitors, High (112.6 FPS) is the recommended choice, as it provides a 6% improvement over Medium (119.7 FPS) is actually lower, so High is the better visual option without a meaningful FPS loss.

Ultra is only advisable for 1080p, where 91.9 FPS remains playable, but it is not recommended for 1440p or 4K due to the 78.9 and 69 FPS results, respectively. Low settings are unnecessary except for the most competitive scenarios, as the 1080p Low result of 165.7 FPS is only 53 FPS higher than High, which is a marginal gain for a significant visual downgrade. The data suggests that the RX 7800 XT’s 16 GB VRAM is best utilized at Medium or High, where the game’s textures load without compromising frame pacing.

How This Combo Ranks

This combination ranks 660th out of 1744 tested combos in Overpower, placing it in the 62nd percentile of all system pairings. This is a solid mid-to-upper tier position, consistent with the GPU’s 76th percentile and the CPU’s 73rd percentile. The ranking suggests that while the RX 7800 XT is a strong performer, the Core i5-10400F’s older Comet Lake architecture (14 nm process, DDR4 memory support) holds the system back from the top echelons. The CPU’s 42.7 GB/s memory bandwidth and PCIe Gen 3 interface are potential limiting factors, as newer platforms offer higher bandwidth.

However, the combo’s 660th rank out of 1744 is not a poor result; it means the system outperforms 62% of tested combinations. The CPU’s 12 MB of L3 cache and 6 cores are sufficient for Overpower’s threading, as evidenced by the 1080p Low result of 165.7 FPS, which is close to the GPU’s maximum output. The GPU’s 76th percentile rank is higher than the combo’s overall rank, indicating that the CPU is the weaker link. Still, the measured FPS at 1440p High (99.8 FPS) and 4K High (83.4 FPS) are competitive, and the combo’s ranking reflects a balanced system for 1440p gaming.

Measured FPS Breakdown

At 1920x1080, the average FPS across settings is: Low 165.7, Medium 119.7, High 112.6, Ultra 91.9. The spread from Low to Ultra is 73.8 FPS, indicating that the GPU scales well with settings at this resolution. At 2560x1440, the averages are: Low 160.1, Medium 107, High 99.8, Ultra 78.9. The drop from Low to Medium is 53.1 FPS, a larger penalty than at 1080p, suggesting the GPU is beginning to feel the resolution load. At 3840x2160, the averages are: Low 144.3, Medium 87.6, High 83.4, Ultra 69. The gap between Medium and High at 4K is only 4.2 FPS, while the gap between High and Ultra is 14.4 FPS, showing that Ultra settings impose a disproportionate cost.

The 4K Low result of 144.3 FPS is notable because it is only 16% lower than the 1080p Low result, whereas the 4K Ultra result is 25% lower than 1080p Ultra. This asymmetry confirms that the GPU’s shading units and ROPs are the bottleneck at Ultra, not the memory subsystem. The 1440p Medium result of 107 FPS is nearly identical to the 1080p High result of 112.6 FPS, suggesting that users can achieve similar frame rates at higher resolutions by dropping one settings tier.

CPU Role

The Intel Core i5-10400F provides a solid foundation with 6 cores and 12 threads, running at a base clock of 2.90 GHz and a boost clock of 4.30 GHz. Its 14 nm Comet Lake architecture and 12 MB of shared L3 cache are sufficient for Overpower, as the game’s Action genre does not demand excessive multi-threading. The CPU’s 3dmark benchmarks show a single-thread score of 688 and a max-thread score of 4735, indicating that single-core performance is modest but adequate. The 73rd percentile ranking among all CPUs, with an average benchmark score of 14168, places it slightly above the AMD EPYC 7552 (14115, 0.4% lower) but below the Intel Core i5-8500 (14332, 1.1% higher).

The CPU’s role is most evident at 1080p Low, where the 165.7 FPS result is likely capped by the CPU’s single-thread throughput, as the GPU has excess capacity. At higher resolutions, the CPU’s impact diminishes, and the GPU becomes the limiting factor. The CPU’s 42.7 GB/s memory bandwidth and DDR4 support are not a hindrance in this game, as the 4K results show no signs of stuttering or frame drops. The 65 W TDP and PCIe Gen 3 interface are adequate for the RX 7800 XT, though the GPU’s PCIe 4.0 x16 interface is not fully utilized. Overall, the CPU holds the system back slightly at 1080p, but at 1440p and 4K, the GPU’s strong performance ensures that the combo remains competitive.
