Overpower

The AMD Ryzen 5 8400F paired with the AMD Radeon RX 570 produces a highly constrained experience in Overpower, with the measured frame rates indicating that the graphics card is the primary bottleneck across all tested resolutions and settings. The data reveals a configuration where CPU headroom is abundant, but the GPU’s aging architecture struggles to maintain playable frame rates under load.

Resolution Scaling

The measured FPS data shows a clear and consistent decline as resolution increases, a pattern that confirms the GPU-bound nature of this configuration. At 1920x1080 with Low settings, the system achieves 63.6 FPS, which drops to 54.8 FPS at 2560x1440 and further to 44.7 FPS at 3840x2160. This represents a 29.7% drop from 1080p to 4K at Low settings, demonstrating that the RX 570 is being pushed progressively harder as pixel count rises.

The scaling behavior changes dramatically when moving to higher presets. At Medium settings, the frame rate falls from 36.3 FPS at 1080p to 37.8 FPS at 1440p, then collapses to 28.4 FPS at 4K. The 1440p result actually being slightly higher than 1080p suggests measurement variance or driver-level frame pacing differences, but the overall trend remains downward. At High settings, the drop is more linear: 33.6 FPS at 1080p, 29.5 FPS at 1440p, and 26.7 FPS at 4K, a 20.5% reduction across the resolution range.

Ultra settings produce the most severe scaling penalty. The configuration manages 29.3 FPS at 1080p, 25.3 FPS at 1440p, and 24.4 FPS at 4K. The relatively small gap between 1440p and 4K at Ultra (0.9 FPS) indicates that the GPU has already saturated its compute resources; additional pixel work yields diminishing returns because the card is fully utilized at both resolutions. This behavior is characteristic of a GPU operating at its absolute limit, where the shader array and memory subsystem cannot keep pace with the workload.

The data suggests that resolution scaling in Overpower is dominated by GPU fill-rate and shading capacity rather than memory bandwidth. The RX 570’s 224.0 GB/s bandwidth and 39.81 GPixel/s pixel rate are simply insufficient for 4K workloads, particularly at higher presets where texture and lighting complexity increases. The fact that Low settings at 4K (44.7 FPS) outperforms Ultra at 1080p (29.3 FPS) by 52.6% underscores how much of the performance ceiling is tied to preset complexity rather than resolution alone.

Settings Recommendations

The measured rows provide a clear hierarchy of playability. Low settings at 1080p is the only configuration that exceeds 60 FPS, hitting 63.6 FPS, which qualifies as smooth for most action titles. Medium settings at 1080p drops to 36.3 FPS, a 42.9% reduction, while High and Ultra yield 33.6 FPS and 29.3 FPS respectively. The step from Low to Medium is the largest single-settings penalty in the entire dataset, indicating that Medium enables computationally expensive effects that disproportionately impact the RX 570.

At 1440p, Low settings delivers 54.8 FPS, which is playable but not consistently smooth. Medium at 1440p falls to 37.8 FPS, and High drops to 29.5 FPS. Ultra at 1440p is effectively unplayable at 25.3 FPS, as is any preset above Low at 4K, where even Low only manages 44.7 FPS. The data indicates that the optimal experience for this configuration is Low settings at 1080p, which provides the only frame rate that comfortably clears the 60 FPS threshold.

For users prioritizing visual fidelity over frame rate, Medium at 1080p (36.3 FPS) offers a marginal improvement over High (33.6 FPS) while consuming fewer GPU resources, making it the better choice among the higher presets. The gap between Medium and High at 1080p is only 2.7 FPS, suggesting that High’s additional effects deliver minimal visual benefit for the performance cost. Ultra should be avoided entirely, as its 29.3 FPS at 1080p is 19.3% slower than Medium and offers no measurable advantage in the measured data.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. Its benchmark results position it as a strong mid-range CPU, with an average benchmark score of 25064 and a percentile ranking of 82 among all CPUs. The nearest rival, the AMD Ryzen 7 2700X, scores 25057, a 0% delta, while the AMD Ryzen 5 7500F scores 24993, a 0.3% delta. This indicates the 8400F is effectively at parity with these processors in overall compute capability.

Single-thread performance is particularly strong, with a 3dmark_single_thread score of 951 and a cinebench_r23_singlecore score of 2943. This is relevant because Overpower is an Action title that likely benefits from high IPC and responsive single-core performance. The multi-threaded results are also robust, with 3dmark_max_threads scoring 6165 and cinebench_r23_multicore reaching 20851. The 12 threads provide sufficient parallelism for modern game engines, though the measured FPS data suggests the CPU is rarely the limiting factor.

The fact that FPS scales almost entirely with resolution and settings, rather than showing CPU-related stutters or inconsistency, indicates the 8400F has ample headroom. At 1080p Low, the configuration achieves 63.6 FPS, which is likely close to the CPU’s maximum frame delivery capability for this title, but the GPU is still the bottleneck at this setting. The 4.20 GHz base clock and 4.70 GHz boost clock provide stable frequency delivery, and the 16 MB shared L3 cache is sufficient for game-level data locality. The 65W TDP and 4nm process node keep thermals manageable, allowing sustained boost clocks during extended sessions.

GPU Role

The AMD Radeon RX 570 is built on the Polaris 20 chip using the GCN 4.0 architecture, manufactured on a 14nm process by GlobalFoundries. It features 2048 shading units, 128 TMUs, and 32 ROPs, with a base clock of 1168 MHz and a boost clock of 1244 MHz. The 4 GB GDDR5 memory operates at 1750 MHz (7 Gbps effective) across a 256-bit bus, yielding 224.0 GB/s of bandwidth. These specifications, while respectable for 2017, place the card at the 74th percentile among all GPUs with an average benchmark score of 30158.

The GPU’s nearest rivals in the benchmark database include the NVIDIA GeForce RTX 5060 (30109, 0.2% delta), AMD Radeon RX 7700 XT (30097, 0.2% delta), and NVIDIA GeForce RTX 5070 Mobile (29928, 0.8% delta). This clustering suggests the RX 570’s average score is competitive with modern mid-range cards, but the Overpower measured data tells a different story. The card’s FP32 throughput of 5.095 TFLOPS and texture rate of 159.2 GTexel/s are the primary drivers of its performance, but these are insufficient for the demands of a 2023 action title at higher settings.

The measured FPS data reveals the RX 570’s limitations clearly. Even at 1080p Low, the card only manages 63.6 FPS, which is likely its ceiling for this title. The pixel rate of 39.81 GPixel/s becomes the limiting factor at 4K, where the card must process four times the pixels of 1080p. The 32 ROPs are a particular constraint, as they handle the final pixel output and are heavily taxed at higher resolutions. The 150W TDP and dual-slot design suggest the card runs at moderate temperatures, but the architecture’s age shows in its inability to scale beyond 1080p Medium settings.

The GPU’s 14nm process node and GCN 4.0 architecture lack modern features like hardware ray tracing or dedicated tensor cores, but Overpower does not appear to rely on these based on the measured data. The bottleneck is purely rasterization throughput, where the RX 570’s 5.095 TFLOPS is simply not competitive with the demands of the title’s High and Ultra presets. The 74th percentile ranking is misleading in this context; the card’s average score is buoyed by synthetic benchmarks that do not reflect real-world gaming workloads.
