Q: Are there any settings where the frame rate stays above 60 FPS consistently?

A: Only one measured configuration exceeds 60 FPS: 1920x1080 with Low settings, which averages 65 FPS. All other settings and resolutions fall below the 60 FPS threshold, with Medium settings at 1080p averaging 41 FPS.

Q: How much does the frame rate improve when lowering resolution from 4K to 1080p at Medium settings?

A: At Medium settings, the average FPS increases from 31 at 3840x2160 to 41 at 1920x1080, a 32% improvement. This modest gain for a 4x reduction in pixel count confirms the system is heavily GPU-bound.

GPU Role

The Intel Arc B370 is the dominant component in this pairing, and its specifications explain the performance ceiling observed in Overpower. The GPU operates with a base clock of 300 MHz and a boost clock of 2400 MHz, built on Intel's 3 nm process with the Xe3-LPG architecture. It features 1280 shading units, 40 texture mapping units, and 20 render output units, along with 10 ray tracing cores.

The memory configuration is critical to understanding the results: the Arc B370 uses System Shared memory, meaning it has no dedicated VRAM. The memory type, bus width, and bandwidth are all listed as System Shared or System Dependent, which means the GPU relies entirely on the system's DDR5 memory. This architectural choice has severe implications for gaming performance, as the shared memory bandwidth cannot rival dedicated graphics memory.

The GPU's raw compute capabilities are modest: 6.144 TFLOPS of FP32 performance and a pixel rate of 48.00 GPixel/s with a texture rate of 96.00 GTexel/s. The 25 W TDP and IGP slot width further confirm this is an integrated-class solution, not a discrete graphics card. The 3DMark Steel Nomad DX12 score of 1184 places it in the 5th percentile of all GPUs, with nearest rivals including the ATI Mobility Radeon HD 5570 (scoring 1186, 0.2% higher) and the ATI Radeon HD 5770 (scoring 1190, 0.5% higher).

In Overpower, the GPU's limitations manifest directly in the measured FPS. The highest average of 65 FPS at 1080p Low is achievable only because the low-quality preset reduces the rendering load to a level the shared-memory architecture can handle. At higher settings, the GPU's fill rate and memory bandwidth constraints become apparent, with Ultra settings at all resolutions yielding average frame rates below 32 FPS.

Settings Recommendations

Based on the measured FPS data, the only configuration that provides a consistently playable experience is 1920x1080 with Low settings, which averages 65 FPS. This is the sole measured point above the 60 FPS threshold, making it the recommended preset for smooth gameplay. The Low preset at 1440p averages 58 FPS, which is close to playable but slightly below the 60 FPS target.

For users who prioritize visual quality over frame rate, Medium settings at 1080p offer a compromise at 41 FPS average, with a minimum of 34 FPS and maximum of 47 FPS. This settings tier provides better visual fidelity than Low while maintaining frame times that may be acceptable for less demanding play styles, though the 34 FPS minimum indicates potential stutter in intense scenes.

High settings are not recommended at any resolution. At 1080p High, the average drops to 38 FPS, and at 1440p High it falls to 34 FPS. The 4K High preset averages just 28 FPS, making it effectively unplayable. Ultra settings should be avoided entirely: the best Ultra result is 31 FPS at 1080p, with 4K Ultra dropping to 24 FPS.

The data suggests that the performance gap between Low and Medium is substantial at every resolution. At 1080p, moving from Low to Medium costs 24 FPS (from 65 to 41), while moving from Medium to High costs only 3 FPS (from 41 to 38). This indicates that the Medium preset is the highest tier that offers any meaningful visual improvement without a disproportionate performance penalty.

Measured FPS Breakdown

At 1920x1080, the full range of settings was tested. Low settings produce the best result with an average of 65 FPS. Medium settings average 41 FPS, with a minimum of 34 FPS and maximum of 47 FPS. High settings average 38 FPS, and Ultra settings average 31 FPS. The spread from Low to Ultra is 34 FPS, representing a 52% performance drop at the highest quality preset.

At 2560x1440, the pattern continues with lower overall performance. Low settings average 58 FPS, which is the only 1440p configuration above 50 FPS. Medium settings average 36 FPS, with a minimum of 31 FPS and maximum of 42 FPS. High settings average 34 FPS, and Ultra settings average 28 FPS. The resolution increase from 1080p to 1440p costs 7 FPS at Low settings (65 to 58) and 5 FPS at Medium settings (41 to 36).

At 3840x2160, performance degrades further. Low settings average 49 FPS, which is the only 4K configuration above 40 FPS. Medium settings average 31 FPS, with a minimum of 26 FPS and maximum of 35 FPS. High settings average 28 FPS, and Ultra settings average 24 FPS. The jump from 1440p to 4K costs 9 FPS at Low settings (58 to 49) and 5 FPS at Medium settings (36 to 31).

The data shows a consistent scaling pattern across all settings tiers. The difference between Low and Medium is consistently the largest gap, averaging 23 FPS across all resolutions. The difference between Medium and High is much smaller, averaging 3 FPS, while the difference between High and Ultra is also consistently 3 FPS. This suggests that the Medium preset represents a significant quality step that the GPU struggles with, while the High and Ultra presets impose incremental costs.

How This Combo Ranks

In the overall ranking for Overpower, this CPU-GPU combination sits at 2742nd out of 2980 tested combos. This places it in the bottom 8% of all configurations, reflecting the significant performance limitation imposed by the Intel Arc B370.

The GPU's individual ranking provides context for this poor showing. The Arc B370 has a percentile rank of 5 among all GPUs tested, with an average benchmark score of 1184 from the 3DMark Steel Nomad DX12 test. Its nearest rivals are all legacy or low-end parts: the ATI Mobility Radeon HD 5570 scores 1186 (0.2% higher), the ATI Radeon HD 5770 scores 1190 (0.5% higher), and the AMD Radeon HD 7650M scores 1192 (0.7% higher). Only the AMD FirePro M2000 scores lower at 1168, which is 1.4% below the Arc B370.

The CPU, by contrast, is a competent mid-range processor. The AMD Ryzen 5 8400F has an average benchmark score of 25005 and ranks in the 77th percentile of all CPUs. Its nearest rivals are closely matched: the AMD Ryzen 5 7500F scores 24964 (0.2% lower), the Intel Core i7-11850H scores 24935 (0.3% lower), and the Intel Core i7-13620H scores 24911 (0.4% lower). The AMD EPYC 9474F scores slightly higher at 25103 (0.4% higher).

The combination of a 77th-percentile CPU with a 5th-percentile GPU creates a severely unbalanced system for gaming. The combo's rank of 2742 out of 2980 reflects the GPU's dominance in determining game performance, as the CPU's capabilities are largely untapped in this workload.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Phoenix. It has a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The CPU features a 4 nm process from TSMC, with 25,000 million transistors on a 178 mm² die.

The cache hierarchy consists of 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. Memory support is limited to DDR5, running on a dual-channel bus with a bandwidth of 83.2 GB/s. The CPU uses the AMD Socket AM5 platform and supports PCIe Gen 4 with 20 lanes.

In synthetic benchmarks, the CPU shows strong multi-threaded performance. The Cinebench R23 multicore score is 20851, while the single-core score is 2943. The 3DMark tests show scaling from 951 in single-thread to 6165 in max threads, with intermediate scores of 1874 for 2 threads, 3563 for 4 threads, and 5275 for 8 threads. PassMark results include a multithread score of 24389 and a single-thread score of 3685.

In Overpower, the CPU's role is to feed the GPU with frame data. Given the GPU's severe limitations, the CPU is rarely the bottleneck. Evidence for this comes from the resolution scaling: if the CPU were the limiting factor, frame rates would remain constant across resolutions. Instead, the data shows clear FPS drops as resolution increases, confirming the GPU is the primary constraint. The CPU has sufficient headroom to handle the game's physics and logic, but this headroom is wasted because the GPU cannot render frames quickly enough to utilize it.

Resolution Scaling

The measured FPS across resolutions reveals a system that is overwhelmingly GPU-bound. From 1080p to 1440p, the average FPS across all settings drops by approximately 15%, while from 1440p to 4K, the drop is approximately 18%. These reductions are relatively modest compared to what would be expected if the system were CPU-bound, where resolution changes would have minimal impact.

At Low settings, the scaling is most pronounced: 65 FPS at 1080p drops to 58 FPS at 1440p (an 11% reduction) and further to 49 FPS at 4K (a 25% reduction from 1440p). This suggests that even at the lowest quality preset, the GPU's shared memory bandwidth cannot sustain higher pixel counts efficiently.

At Medium settings, the pattern is similar but with a smaller absolute drop: 41 FPS at 1080p falls to 36 FPS at 1440p (12% reduction) and 31 FPS at 4K (14% reduction from 1440p). The minimum FPS values also scale consistently: 34 at 1080p, 31 at 1440p, and 26 at 4K.

The scaling behavior indicates that the limiting component is the GPU's rendering pipeline rather than memory bandwidth alone. If memory bandwidth were the sole constraint, the performance drop from 1080p to 4K would be much steeper, approaching the 4x pixel count increase. Instead, the system loses only 52% of its performance from 1080p to 4K at Low settings (65 to 49 FPS), suggesting that the GPU's compute units and fill rate are also significant constraints.

The CPU's role in this scaling is minimal. With a strong multi-threaded score of 20851 in Cinebench R23 and a 77th-percentile ranking, the Ryzen 5 8400F has ample processing power to maintain frame pacing at 4K. The fact that frame rates still drop substantially at higher resolutions confirms that the Arc B370 is the definitive bottleneck, and no CPU-side optimization could meaningfully improve the results.
