GPU Role

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, built on Intel's 3nm process node. It carries 1536 shading units, 48 texture mapping units, and 24 ROPs, along with 12 ray tracing cores. The GPU operates at a base clock of 300 MHz and boosts to 2500 MHz, producing a pixel rate of 60.00 GPixel/s, a texture rate of 120.0 GTexel/s, and 7.680 TFLOPS of FP32 compute. Memory is system-shared, with bandwidth listed as system dependent — meaning the GPU relies on the host system's DDR5 memory rather than dedicated VRAM.

In Overpower, the Arc B390's performance profile is consistent with its hardware specifications. The GPU's percentile rank of 9 versus all GPUs indicates it performs better than only about 9% of the graphics cards in the database. Its sole benchmark score, 1482 in 3DMark Steel Nomad DX12, places it in direct competition with decade-old NVIDIA parts like the GT 520MX (1463) and GT 710 (1443). This positions the Arc B390 as an entry-level solution that can run modern games at lower settings but lacks the headroom for demanding configurations.

The GPU's integrated nature means it shares system memory bandwidth with the CPU. This explains why frame rates scale steeply with resolution changes: the system-shared memory architecture becomes a bottleneck as pixel count increases. At 1080p Low, the combo achieves 72 FPS, but at 4K Low that drops to 54 FPS — a 25% reduction. The GPU's 24 ROPs and 48 TMUs are sufficient for 1080p rendering but struggle to fill 4K frames, as evidenced by the 26 FPS Ultra result at 3840x2160.

The Arc B390's ray tracing cores (12) and DirectX 12 Ultimate support are present in the hardware, but the measured FPS data shows the GPU is primarily compute-bound in Overpower. The game's action genre likely benefits from the GPU's 7.680 TFLOPS FP32 throughput at lower resolutions, but the integrated design's lack of dedicated VRAM and system-dependent bandwidth cap performance well below discrete GPU territory.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor from the 8000 series, built on the Zen 4 architecture with the Phoenix codename. It operates at a base clock of 4.20 GHz and boosts to 4.70 GHz, with a 65W TDP. The CPU features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. It supports dual-channel DDR5 memory with a bandwidth of 83.2 GB/s and connects via PCIe Gen 4 with 20 lanes. The processor is manufactured on TSMC's 4nm process node with 25,000 million transistors on a 178 mm² die.

The Ryzen 5 8400F's benchmark performance shows strong multi-threaded capability relative to its peers. In Cinebench R23, it scores 20851 multi-core and 2943 single-core. Its average benchmark score of 25005 places it in the 77th percentile of all CPUs, with nearest rivals including the Ryzen 5 7500F (0.2% ahead), Core i7-11850H (0.3% ahead), and Core i7-13620H (0.4% ahead). The CPU's 3DMark scores scale well from 2 threads (1874) to 16 threads (6091), indicating efficient thread utilization.

In Overpower, the CPU's role appears secondary to the GPU bottleneck. At 1080p Low, the combo produces 72 FPS — a result that aligns with the GPU's capabilities rather than the CPU's. The Ryzen 5 8400F, with a passmark multithread score of 24389 and single-thread score of 3685, is more than capable of feeding frames to the Arc B390 at these settings. The 4.70 GHz boost clock and 12 threads provide ample headroom for the game's action genre, which typically demands responsive single-thread performance and background task handling.

The CPU's 83.2 GB/s memory bandwidth is shared with the integrated GPU, creating a potential contention point. However, the measured FPS data shows the CPU is not the limiting factor at any resolution. The consistency of frame rates across settings — for example, 42 FPS at 1080p High versus 45 FPS at 1080p Medium — suggests the GPU's rendering pipeline, not the CPU's instruction throughput, determines the final output. The CPU's 25,000 million transistors and 4nm process give it enough computational headroom to handle Overpower's physics and AI without becoming a bottleneck.

How This Combo Ranks

The AMD Ryzen 5 8400F + Intel Arc B390 combination ranks 2638th out of 2980 tested combos in Overpower, placing it in the bottom 11.5% of all configurations. This ranking reflects the severe imbalance between a high-percentile CPU and a low-percentile GPU. The CPU sits in the 77th percentile of all processors, while the GPU sits in the 9th percentile of all graphics cards. This 68-percentile gap is one of the largest mismatches possible in a tested combo.

The combo's rank of 2638 means there are 2637 configurations that perform better in Overpower, and only 342 that perform worse. This places the combo in the company of systems using entry-level or integrated graphics, despite the Ryzen 5 8400F being a modern desktop processor. The GPU's 1482 Steel Nomad score, which rivals the GeForce GT 520MX (1463) and GT 710 (1443), anchors the combo's performance to the bottom of the GPU hierarchy.

The CPU's nearest rivals — the Ryzen 5 7500F (0.2% ahead), Core i7-11850H (0.3% ahead), Core i7-13620H (0.4% ahead), and EPYC 9474F (0.4% behind) — all have similar average scores around 25000. This indicates that swapping the 8400F for any of these CPUs would have a minimal impact on Overpower performance, as the GPU remains the dominant constraint. The combo's rank is therefore determined almost entirely by the Arc B390's capabilities.

For context, the combo's 72 FPS at 1080p Low places it in the range of systems that can handle Overpower at reduced settings, but the 26 FPS at 4K Ultra shows the ceiling of this configuration. The ranking reflects this: it is not a competitive gaming combo, but it can provide a functional experience at lower settings and resolutions.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average of 72 FPS, which is the highest frame rate recorded across all configurations. Medium settings achieve 45 FPS with a minimum of 38 FPS and a maximum of 52 FPS. High settings drop to 42 FPS, and Ultra settings fall further to 35 FPS. The 1080p results show a clear step-down from Low to Medium (27 FPS difference), followed by a smaller gap between Medium and High (3 FPS), and a 7 FPS drop from High to Ultra.

At 2560x1440, performance decreases across the board. Low settings average 64 FPS, a 12.5% reduction from 1080p Low. Medium settings average 40 FPS with a range of 34 to 46 FPS. High settings reach 37 FPS, and Ultra drops to 31 FPS. The 1440p results show a 24 FPS difference between Low and Ultra, with the step from Medium to High being only 3 FPS again.

At 3840x2160, the combo's limitations become pronounced. Low settings average 54 FPS, which is still playable but 25% lower than 1080p Low. Medium settings average 34 FPS with a minimum of 29 FPS and maximum of 39 FPS. High settings drop to 32 FPS, and Ultra falls to 26 FPS. The 4K Ultra result is below the 30 FPS playability threshold, making it unsuitable for smooth gameplay.

The complete FPS dataset shows a consistent pattern: Low settings are the only option that maintains above-60 FPS (at 1080p and 1440p), Medium and High settings cluster in the 32-45 FPS range, and Ultra settings consistently land in the 26-35 FPS range. The minimum FPS data points, available only for Medium settings, show that frame time consistency degrades at higher resolutions: 38 FPS minimum at 1080p, 34 FPS at 1440p, and 29 FPS at 4K.

Settings Recommendations

Based on the measured FPS data, Low settings at 1920x1080 provide the best experience for this combo. The 72 FPS average is the only result that comfortably exceeds 60 FPS, ensuring smooth gameplay for the action genre. At 1440p Low, the 64 FPS average is also playable, but the 12.5% frame rate reduction makes 1080p the safer choice for consistent performance.

For users who prefer higher visual quality, Medium settings at 1080p (45 FPS) or 1440p (40 FPS) are viable options. The minimum FPS of 38 at 1080p and 34 at 1440p indicates that frame drops will occur but remain within tolerable bounds. High settings offer marginal improvements over Medium (3 FPS at both 1080p and 1440p) but come with the loss of minimum FPS data, suggesting less predictable frame pacing.

Ultra settings are not recommended for this combo. The 35 FPS at 1080p, 31 FPS at 1440p, and 26 FPS at 4K all fall below the 60 FPS standard for action games, and the 4K result is below 30 FPS. The visual quality gains from Ultra do not justify the substantial performance cost, especially when the GPU's 7.680 TFLOPS FP32 throughput is already strained.

The optimal configuration is Low settings at 1080p for maximum frame rate, with Medium at 1080p as a compromise for better visuals. At 1440p, Low remains the only recommended setting, while 4K should be avoided entirely except for static scenes or screenshot purposes.

Resolution Scaling

The measured FPS data reveals a clear resolution scaling pattern for this combo. From 1080p to 1440p, frame rates drop by an average of 11-12% across settings: Low falls from 72 to 64 FPS, Medium from 45 to 40 FPS, High from 42 to 37 FPS, and Ultra from 35 to 31 FPS. This consistent percentage reduction indicates a predictable GPU-bound scaling behavior.

From 1440p to 4K, the scaling becomes more pronounced. Low settings drop from 64 to 54 FPS (15.6% reduction), Medium from 40 to 34 FPS (15% reduction), High from 37 to 32 FPS (13.5% reduction), and Ultra from 31 to 26 FPS (16.1% reduction). The larger percentage drops at 4K suggest the system-shared memory bandwidth becomes a more significant constraint as pixel count increases.

The overall scaling from 1080p to 4K shows the following reductions: Low settings lose 18 FPS (25%), Medium loses 11 FPS (24.4%), High loses 10 FPS (23.8%), and Ultra loses 9 FPS (25.7%). This remarkably consistent 24-26% reduction across all settings indicates that the limiting component scales linearly with resolution — a characteristic of a GPU that is bandwidth-bound rather than compute-bound.

The data points to the Intel Arc B390 as the primary limiting component. The CPU's 83.2 GB/s memory bandwidth is shared with the GPU, and as resolution increases, the GPU requires more memory bandwidth to fill pixels. The 24 ROPs and 48 TMUs of the Arc B390 are insufficient for 4K rendering, as evidenced by the 26 FPS Ultra result. The CPU, with its 77th percentile ranking and Cinebench R23 multicore score of 20851, shows no signs of bottlenecking — the frame rate drops are entirely attributable to the GPU's pixel throughput limitations.

The resolution scaling behavior confirms that this combo is GPU-limited at all settings and resolutions. The Ryzen 5 8400F has ample headroom to drive the Arc B390 to its maximum potential, but that potential is modest. For users of this combo, the data clearly indicates that 1080p is the target resolution, and Low-to-Medium settings are the practical ceiling for smooth gameplay in Overpower.
