Overpower

The AMD Radeon RX 6750 XT paired with the Intel Core i5-9400 delivers a robust 1080p and 1440p experience in Overpower, though 4K Ultra demands compromise. The data shows a system where the GPU is the primary driver of frame rates, but the CPU’s six threads begin to limit performance at lower resolutions and higher refresh rates. This analysis breaks down the measured performance across all 12 tested configurations, contextualizing each result against the combo’s overall rank and the hardware’s architectural traits.

Resolution Scaling

The measured FPS data reveals a clear pattern of diminishing returns as resolution increases, with the most significant drops occurring between 1080p and 1440p. At High settings, the average frame rate falls from 95.3 FPS at 1920x1080 to 81.7 FPS at 2560x1440, a reduction of roughly 14%. Scaling further to 3840x2160 yields 70.4 FPS, a further 14% drop from the 1440p figure. This steady decline indicates that the GPU’s rendering pipeline is the primary constraint, as the workload per pixel increases linearly with resolution.

The scaling behavior shifts dramatically when examining Low settings. The 1920x1080 Low result of 157.7 FPS drops to 147 FPS at 2560x1440 (a 7% decrease), then falls to 122.8 FPS at 4K (a 16% decrease). The smaller gap between 1080p and 1440p at Low settings suggests that the CPU is beginning to influence performance at the lowest resolution, where the GPU has ample headroom. At 4K Low, the GPU becomes the clear bottleneck again, as the absolute frame rate drop is larger.

Ultra settings present the most demanding scenario, with the frame rate declining from 75.5 FPS at 1080p to 68.4 FPS at 1440p (a 9% drop) and finally to 59.7 FPS at 4K (a 13% drop). The percentage reductions are smaller than those seen at High settings, which is typical for GPU-bound workloads where the base frame rate is already lower. The overall trend confirms that Overpower scales predictably with resolution, and the RX 6750 XT maintains playable frame rates up to 4K High, though Ultra at 4K dips below the 60 FPS threshold.

GPU Role

The AMD Radeon RX 6750 XT is the dominant component in this pairing, and its specifications align well with the observed frame rates. The GPU features 12 GB of GDDR6 memory on a 192-bit bus, yielding a bandwidth of 432.0 GB/s. This memory configuration is sufficient for the texture and geometry demands of Overpower at all tested resolutions, as evidenced by the relatively smooth scaling from 1080p to 4K without catastrophic frame rate collapses that would indicate memory capacity issues.

Clock speeds are notably high, with a base clock of 2150 MHz and a boost clock of 2600 MHz. The game clock of 2495 MHz represents the typical sustained frequency during gaming workloads, and this aggressive clocking contributes to the GPU’s strong performance in synthetic benchmarks. The GPU’s 13.31 TFLOPS of FP32 compute power and 416.0 GTexel/s texture rate provide ample raw throughput for an action title like Overpower, which benefits from high pixel fill rates and shader complexity.

The GPU’s 40 ray tracing cores are present but likely underutilized in this title, as the measured settings do not specify ray tracing effects. The 64 ROPs ensure adequate pixel throughput for the 4K resolution, where the 59.7 FPS Ultra result indicates the GPU is working near its limits. The 250 W TDP and dual-slot design suggest this is a power-hungry part, but the benchmark data does not include power consumption figures, so conclusions are limited to performance metrics only.

How This Combo Ranks

The combination of the Intel Core i5-9400 and AMD Radeon RX 6750 XT ranks 885th out of 1744 tested combos in Overpower. This places the system in the 49th percentile of all combinations, indicating a mid-pack performance tier. The rank reflects the balance between the GPU’s strong 79th percentile standing among all GPUs and the CPU’s 50th percentile position among all CPUs.

The GPU’s average benchmark score of 35327 places it near the AMD Radeon RX 5600M, which scores 35264 (a 0.2% delta), and slightly below the NVIDIA GeForce RTX 3080, which scores 35787 (a -1.3% delta). This proximity to the RTX 3080 in aggregate benchmarks is notable, though it does not guarantee identical gaming performance. The CPU’s average benchmark score of 2305 is nearly identical to the Intel Core i3-10305 at 2300 (a 0.2% delta) and the Intel Xeon E-2134 at 2295 (a 0.4% delta).

The combo rank of 885 out of 1744 suggests that while the GPU is capable, the CPU holds the system back from higher placements. For a game like Overpower, the combination’s rank indicates that many other tested configurations achieve higher frame rates, likely those with stronger processors paired with similar or better GPUs.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 157.7 FPS, which is the maximum measured across all configurations. Medium settings yield 103.9 FPS, High settings result in 95.3 FPS, and Ultra settings drop to 75.5 FPS. The gap between Low and Medium is substantial at 53.8 FPS, indicating that the Low preset removes significant rendering work, likely related to shadows and post-processing effects.

Moving to 2560x1440, the frame rates remain strong. Low settings average 147 FPS, a modest decline from 1080p, while Medium settings produce 87.5 FPS and High settings reach 81.7 FPS. Ultra settings at 1440p yield 68.4 FPS, which is still comfortably above 60 FPS. The scaling from Medium to High at this resolution is only 5.8 FPS, suggesting that the High preset adds relatively little overhead compared to Medium.

At 3840x2160, the GPU’s limits become apparent. Low settings average 122.8 FPS, which is surprisingly high for 4K, indicating that the Low preset is not heavily pixel-bound. Medium settings produce 79.2 FPS, High settings reach 70.4 FPS, and Ultra settings drop to 59.7 FPS. The 4K Ultra result is the only configuration that falls below 60 FPS, making it the threshold for smooth gameplay at maximum quality.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on the Coffee Lake architecture, manufactured on a 14 nm process. Its base clock of 2.90 GHz and boost clock of 4.10 GHz provide adequate single-thread performance, as reflected in its Cinebench R23 single-core score of 1125. The lack of hyper-threading means the CPU handles 6 threads simultaneously, which is sufficient for most games but can become a limitation in heavily threaded scenarios.

The CPU’s multi-core performance is modest, with a Cinebench R23 multi-core score of 7969. This places the processor in the 50th percentile of all CPUs, indicating average performance. In Overpower, the CPU’s role is to feed the GPU with draw calls and game logic, and the measured frame rates suggest that at 1080p Low, the CPU is the limiting factor. The 157.7 FPS result at 1080p Low is significantly higher than the 4K Low result of 122.8 FPS, but the gap between 1080p and 1440p at Low settings is only 10.7 FPS, indicating that the CPU is struggling to maintain frame rates above 150 FPS.

The CPU’s 9 MB of shared L3 cache and dual-channel DDR4 memory support with 42.7 GB/s bandwidth are adequate for this title. The processor’s PCIe Gen 3 interface with 16 lanes provides sufficient bandwidth for the RX 6750 XT, which uses a PCIe 4.0 x16 interface but is backward compatible. The CPU’s integrated UHD 630 graphics are irrelevant for this discrete GPU configuration.

The benchmark results indicate that the CPU is not a bottleneck at 4K or at High/Ultra settings at lower resolutions, where the GPU is clearly the limiting component. However, the 1080p Low result of 157.7 FPS suggests that the CPU’s 6 threads cannot sustain frame rates beyond this level, even with a GPU capable of higher output. This is consistent with the CPU’s 50th percentile ranking and its average benchmark score of 2305, which is nearly identical to the Core i3-10305 and Xeon E-2134.
