Overpower

The AMD Ryzen 5 4600G and Intel Arc B390 combination delivers a playable but hardly luxurious experience in Overpower, with performance that lands firmly in the lower percentile of tested systems. The pairing of a 2020-era six-core APU with an integrated-class Intel GPU produces frame rates that are workable at 1080p with reduced settings, but the data shows a rapid falloff as resolution and quality demands increase. This is a combo built for esports-level tweaking rather than high-fidelity immersion.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, fabricated on a 7 nm process at TSMC. Its base clock of 3.70 GHz can boost up to 4.20 GHz, and it carries an 8 MB shared L3 cache alongside 512 KB of L2 per core. In the context of Overpower, an action title released in August 2023, this CPU provides a solid logical foundation. With a 65 W TDP and support for dual-channel DDR4 memory, the processor is not the primary bottleneck in most of the measured scenarios, but its capabilities do set a ceiling for how much performance the system can extract when the GPU is less stressed.

The CPU’s benchmark scores paint a picture of a competent mid-range part. Its Cinebench R23 multicore score of 13593 and single-core score of 1919 indicate that it can handle the game’s threading requirements without major issue. The Geekbench multicore result of 6637 and single-core result of 1460 further support this. In the Passmark suite, the multithread score of 15992 and single-thread score of 2653 show balanced performance. The processor’s percentile ranking of 71 among all CPUs means it outperforms the majority of installed processors, which is notable for a chip launched in July 2020. When compared to its nearest rivals, the Ryzen 5 4600G sits in a tight cluster: it is 0.1% faster than the AMD Ryzen 3 PRO 5355GE and 0.6% faster than the Intel Core 7 150U, while trailing the AMD Ryzen 3 8300GE by 0.6% and the Intel Core i3-14100T by 0.8%. These deltas are negligible in real-world gaming terms, meaning the CPU is effectively on par with its direct competitors.

In Overpower, the CPU’s role is to feed the GPU with draw calls and handle game logic. Given that the lowest measured average FPS at 1080p is 35 (Ultra settings) and the highest is 72 (Low settings), the CPU is clearly capable of pushing well beyond the GPU’s limits at lower resolutions. The 3DMark single-thread score of 726 and 2-thread score of 1430 suggest that the processor has enough single-core grunt for the game’s primary thread, while the 16-thread score of 4863 and max-thread score of 4889 indicate that multi-threaded workloads are handled with ease. The processor’s memory bandwidth of 51.2 GB/s over a dual-channel bus is adequate for this title, but it is not a strength. The data implies that the Ryzen 5 4600G is not the limiting factor in this combo; it is the integrated GPU that holds the system back.

GPU Role

The Intel Arc B390 is the dramatic weak link in this pairing. It is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, built on Intel’s 3 nm process. Its core clocks are listed at a base of 300 MHz and a boost of 2500 MHz, but the memory configuration is the critical detail: it uses "System Shared" memory, meaning it borrows from the main system RAM rather than having its own dedicated VRAM. This has profound implications for gaming performance, as the GPU must compete with the CPU for memory bandwidth.

The GPU’s benchmark results are damning. Its only listed 3DMark Steel Nomad DX12 score is 1482, which places it in the 9th percentile of all GPUs. This is a staggeringly low ranking, indicating that the Arc B390 is outperformed by the vast majority of discrete graphics cards. The nearest rivals are all ancient or entry-level NVIDIA parts: the GeForce GT 520MX (1.3% slower), GeForce 800M (1.5% slower), GeForce GT 625 OEM (2.5% slower), and GeForce GT 710 (2.7% slower). The fact that this Intel IGP is only slightly faster than a GT 710, a card from over a decade ago, underscores its limited capabilities. The GPU’s shading units number 1536, with 48 TMUs and 24 ROPs, and it has 12 ray tracing cores. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are modest, and the FP32 throughput of 7.680 TFLOPS is not enough for demanding modern titles.

In Overpower, the Arc B390’s lack of dedicated VRAM and low raw compute power means it is the dominant bottleneck in every measured configuration. The performance scales almost linearly with resolution and settings, which is a classic sign of a GPU that is saturated. At 1080p Low, the GPU manages 72 FPS, but this drops to 42 FPS at High and 35 FPS at Ultra. These numbers are consistent with a GPU that is maxed out on fill rate and memory bandwidth. The 80 W TDP for the IGP is low, but that is irrelevant when the performance is this constrained. The data clearly shows that any attempt to increase graphical fidelity is met with severe frame rate penalties, making the Arc B390 the sole arbiter of this system’s gaming experience.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, and this pattern is directly attributable to the GPU’s limitations. Starting at 1920x1080 with Low settings, the system achieves 72 FPS. Moving to 2560x1440 at the same settings drops the frame rate to 64 FPS, a reduction of 8 FPS or approximately 11%. Pushing to 3840x2160 at Low settings yields 54 FPS, a further drop of 10 FPS from 1440p. This scaling is steep but manageable at the lowest quality preset.

However, the story changes dramatically at higher settings. At High settings, the average FPS goes from 42 at 1080p, to 37 at 1440p, and finally to 32 at 4K. The drop from 1080p to 4K is 10 FPS, or about 24%, which is a relatively shallow decline compared to what one might expect from a discrete GPU. This shallow decline is a strong indicator that the GPU is already overwhelmed at 1080p High, and the additional resolution is not the primary factor; rather, the GPU is hitting its compute ceiling. The same effect is visible at Medium settings, where the system goes from 45 FPS at 1080p, to 40 FPS at 1440p, and 34 FPS at 4K. The Ultra preset shows the worst absolute numbers: 35 FPS at 1080p, 31 FPS at 1440p, and 26 FPS at 4K.

The pattern here is that the frame rate drops are not proportional to the pixel count increase. For instance, moving from 1080p to 4K quadruples the pixel count, yet the FPS does not drop by a factor of four. This indicates that the system is not purely pixel-bound; it is likely limited by the GPU’s shader throughput and memory subsystem. The Arc B390’s reliance on system memory, which is shared with the CPU, creates a situation where the memory bandwidth is the limiting factor rather than the raw pixel fill rate. The data suggests that the CPU is never the bottleneck at any resolution, as the FPS differences between 1080p and 4K are relatively modest in absolute terms. This combo is clearly GPU-limited across the board, and the resolution scaling behavior confirms that the Intel Arc B390 is the component that dictates the playable envelope.

Measured FPS Breakdown

The full set of measured frame rates provides a granular view of the system’s capabilities. At 1920x1080, the lowest resolution tested, the system performs best on the Low preset with an average of 72 FPS. The Medium preset drops to 45 FPS, with a minimum of 38 FPS and a maximum of 52 FPS. High settings yield 42 FPS, and Ultra settings bring the average down to 35 FPS. None of these numbers are particularly impressive, but the 1080p Low result is the only configuration that approaches what could be considered a comfortable gaming experience.

At 2560x1440, the performance degrades further. The Low preset averages 64 FPS, which is still playable, but the Medium preset falls to 40 FPS with a minimum of 34 FPS and a maximum of 46 FPS. High settings produce 37 FPS, and Ultra settings drop to 31 FPS. The data shows that 1440p is only viable at Low settings, and even then, the frame rate is not high enough for fast-paced action titles if the player prefers smoothness over visuals.

At 3840x2160, the system struggles to maintain playable frame rates. The Low preset averages 54 FPS, which is surprising given the resolution, but it is the only 4K configuration that breaks the 30 FPS threshold. Medium settings average 34 FPS with a minimum of 29 FPS and a maximum of 39 FPS. High settings drop to 32 FPS, and Ultra settings bottom out at 26 FPS. The 4K results are largely academic, as they are below the threshold for smooth gameplay in an action title. The minimum FPS of 29 at 4K Medium indicates that the system can stutter, which would be noticeable during intense scenes. The data across all resolutions shows a consistent pattern: the Intel Arc B390 is the limiting factor, and the Ryzen 5 4600G has ample headroom that is never utilized.

How This Combo Ranks

The combo of the AMD Ryzen 5 4600G and Intel Arc B390 ranks 2638 out of 2980 tested combinations in Overpower. This places it in the bottom 11.5% of all systems, which is a poor showing. The rank is a direct reflection of the GPU’s low benchmark scores. The Arc B390’s 9th percentile ranking among all GPUs is the primary driver of this poor result. In contrast, the CPU’s 71st percentile ranking is a non-factor in the overall combo rank, because the GPU is so severely underpowered that it negates any CPU advantage.

The nearest rival GPUs, such as the GeForce GT 710 and GT 625 OEM, are all significantly older and less capable in other contexts, but in Overpower, they are effectively in the same performance class as the Arc B390. This means that the combo rank is not an outlier; it is representative of a system that is built around a low-end integrated GPU. The data indicates that this combo is not suitable for modern gaming at high settings, and its rank reflects that reality. The 2638th position out of 2980 is a clear warning to users that this system will require significant compromises to run the game at all.

Settings Recommendations

Given the measured data, the optimal configuration for this combo is to prioritize frame rate over visual fidelity. The only settings that provide a consistently smooth experience are the Low presets. At 1920x1080 with Low settings, the system achieves 72 FPS, which is the best result in the entire dataset. This is the recommended starting point for any user who wants to play Overpower without significant stutter. The Medium preset at 1080p, which averages 45 FPS, is a viable alternative for users who want slightly better visuals and can tolerate a lower frame rate, but the minimum FPS of 38 suggests it may not be stable during heavy action.

For users with a 2560x1440 monitor, the Low preset at 64 FPS is the only sensible choice. The Medium preset at 40 FPS is borderline, but the minimum of 34 FPS makes it a risky proposition. At 3840x2160, the Low preset at 54 FPS is the only playable option, but users should be aware that this is a marginal experience. The High and Ultra presets are not recommended at any resolution, as they all fall below 45 FPS and often dip into the 20s and 30s. The data shows that the Ultra preset at 4K, at 26 FPS, is essentially unplayable. The best experience per the measured rows is unequivocally the 1080p Low configuration, which offers the highest frame rate and the most stable performance. Users should avoid the High and Ultra presets entirely, as the GPU lacks the necessary compute power to handle them. The system is best treated as a 1080p Low-settings machine for this game, and any attempt to increase quality will result in a poor experience.
