Overpower

The Intel Core i5-9400 paired with the AMD Radeon RX 570 delivers a playable but constrained experience in Overpower, with the GPU acting as the clear performance ceiling at every resolution. The data shows a system that can hit smooth frame rates only when graphical demands are minimized, and the overall combination ranks in the bottom 5% of tested configurations.

Resolution Scaling

The frame rate drop from 1080p to 4K is severe and consistent across all settings, confirming that the Radeon RX 570 is the limiting component in this pairing. At Low settings, performance falls from 62.6 FPS at 1920x1080 to 48.6 FPS at 3840x2160, a reduction of 22.4%. The scaling becomes more punishing at higher presets. At High settings, the average drops from 37.0 FPS at 1080p to 33.1 FPS at 1440p, then further to 25.5 FPS at 4K. This represents a 31.1% loss from 1080p to 4K.

The pattern is similar for Medium and Ultra presets. At Medium, the system produces 39.4 FPS at 1080p, 35.9 FPS at 1440p, and 28.5 FPS at 4K. At Ultra, the numbers are 33.1, 28.0, and 21.1 FPS respectively. The relatively small performance gap between 1080p and 1440p at every setting, compared to the larger gap when moving to 4K, indicates that the GPU's 224.0 GB/s memory bandwidth and 256-bit bus are being saturated. The RX 570 has only 4 GB of GDDR5 memory, and the data suggests that at 4K resolution, the combination of memory capacity and bandwidth becomes a hard wall.

The 1080p to 1440p scaling is notably mild. At Low settings, the drop is only 10.7% (62.6 to 55.9 FPS). This suggests that at these resolutions, the CPU can still feed the GPU sufficiently, but the GPU is already near its architectural limits. The 4K results are uniformly below the 30 FPS threshold for playability, even at Low settings, making 4K a non-viable target for this combo.

GPU Role

The AMD Radeon RX 570 is a Polaris 20 chip built on a 14 nm process at GlobalFoundries, featuring 2,048 shading units, 128 texture mapping units, and 32 ROPs. It runs at a base clock of 1168 MHz and a boost clock of 1244 MHz. The memory operates at 1750 MHz, effectively 7 Gbps, across a 256-bit bus, yielding 224.0 GB/s of bandwidth. The card's 4 GB VRAM capacity is the primary constraint in Overpower.

The benchmark results show the GPU's compute capabilities: 5.095 TFLOPS FP32 performance and a texture rate of 159.2 GTexel/s. Despite these specifications, the measured FPS reveals that the card is struggling. The gap between Low and Ultra settings at 1080p is 29.5 FPS (62.6 vs 33.1), showing that the GPU is heavily taxed by higher-quality textures and effects. The VRAM capacity is likely the culprit at higher presets, as 4 GB is insufficient for Ultra textures at 1080p in this title.

The GPU's nearest rivals in the benchmark database have nearly identical average scores. The NVIDIA GeForce RTX 5060 scores 30,109 (0.2% higher), the AMD Radeon RX 7700 XT scores 30,097 (0.2% higher), and the NVIDIA Tesla M60 scores 29,969 (0.6% higher). This places the RX 570 in a very tight performance band, but the 4 GB VRAM limitation is a differentiator in games like Overpower that scale heavily with memory. The card's 74th percentile ranking among all GPUs indicates it is above average in synthetic benchmarks, yet the game-specific data shows its real-world limits.

How This Combo Ranks

This specific pairing of the Intel Core i5-9400 and AMD Radeon RX 570 ranks 1653 out of 1744 tested combinations in Overpower. This places it in the bottom 5.2% of all combos, indicating that it is one of the weaker configurations for this particular title. The rank reflects the combined limitations of a mid-range CPU from 2018 and a GPU from 2017.

The CPU itself has a 50th percentile ranking among all CPUs, with an average benchmark score of 2305. Its nearest rivals are very close: the Intel Core i3-10305 scores 2300 (0.2% higher), the Intel Core i3-1125G4 scores 2299 (0.2% higher), and the Intel Xeon E-2134 scores 2295 (0.4% higher). The Intel Core i7-8809G scores 2319, which is 0.6% higher. This shows the i5-9400 is a solidly average processor, but it is not the bottleneck here.

The GPU's 74th percentile ranking suggests it should perform better than it does in this game. The combination's poor rank is a direct consequence of the GPU's 4 GB memory limitation, which is exposed by Overpower's high memory usage at higher settings. The data indicates that this combo is best suited for Low settings at 1080p or 1440p, where it can approach playable frame rates.

Measured FPS Breakdown

At 1920x1080, the results are as follows: Low settings produce an average of 62.6 FPS, which is the only configuration that exceeds the 60 FPS threshold. Medium settings yield 39.4 FPS, High settings yield 37.0 FPS, and Ultra settings yield 33.1 FPS. The difference between Medium and High is minimal (2.4 FPS), suggesting that the High preset does not add a significant load compared to Medium.

At 2560x1440, the averages drop: Low settings produce 55.9 FPS, Medium produces 35.9 FPS, High produces 33.1 FPS, and Ultra produces 28.0 FPS. The Low preset remains playable, but the jump from Low to Medium is substantial, a loss of 20.0 FPS. This indicates that the Medium preset introduces a significant graphical feature that heavily taxes the GPU at this resolution.

At 3840x2160, all settings are below playable thresholds: Low produces 48.6 FPS, Medium produces 28.5 FPS, High produces 25.5 FPS, and Ultra produces 21.1 FPS. Even the Low preset, which is the best 4K result, is only marginally playable and would be unsuitable for fast-paced action. The scaling from 1440p to 4K is steep, confirming that the GPU's memory and compute resources are exhausted.

Settings Recommendations

The data strongly indicates that the Low preset at 1920x1080 is the only configuration that delivers a consistently smooth experience, averaging 62.6 FPS. This is the recommended setting for competitive play or any scenario where frame rate is prioritized. The Low preset at 2560x1440 also provides 55.9 FPS, which is acceptable for most players, but the 1080p option offers more headroom for frame time spikes.

For players who prefer higher visual fidelity, the Medium preset at 1080p (39.4 FPS) is the best compromise, as it is above the 30 FPS minimum and provides a more detailed image than Low. The High preset at 1080p (37.0 FPS) is nearly identical in performance to Medium, so it can be selected without a major penalty. The Ultra preset at any resolution is not recommended, as it yields 33.1 FPS at 1080p and drops below 30 FPS at 1440p.

The 4K resolution should be avoided entirely. Even the best 4K result (48.6 FPS at Low) is below the 60 FPS target, and the higher presets are unplayable. The data suggests that this combination is not suited for 4K gaming in Overpower, and users should target 1080p or 1440p with Low or Medium settings.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor from the Coffee Lake architecture, manufactured on a 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.10 GHz, with a 65 W TDP. The CPU features 9 MB of shared L3 cache, with 64 KB of L1 and 256 KB of L2 per core. It supports dual-channel DDR4 memory with a bandwidth of 42.7 GB/s.

In synthetic benchmarks, the i5-9400 scores 7,969 in Cinebench R23 multi-core and 1,125 in single-core. The data shows that the CPU is not the limiting factor in Overpower. The frame rate scaling from 1080p to 4K is consistent with a GPU-bound scenario, where the CPU can maintain frame delivery but the GPU cannot render fast enough. The CPU's 50th percentile ranking confirms it is an average performer, but it does not drag down the results.

The CPU's nearest rivals are extremely close in performance, with deltas under 1%. This indicates that swapping the i5-9400 for a comparable CPU would not meaningfully change the Overpower results. The bottleneck is clearly the GPU, specifically its 4 GB VRAM capacity and 224.0 GB/s bandwidth, which are insufficient for higher settings at 1440p and 4K. The CPU's 6 cores and 6 threads are adequate for this title, as evidenced by the fact that the frame rate drops are directly proportional to resolution and settings increases, not CPU load.
