Overpower

The AMD Ryzen 5 7500X3D paired with the Intel Arc B390 presents a stark contrast in component tiers. The CPU is a high-end desktop processor, while the GPU is an integrated mobile-class part. This combination produces a heavily GPU-limited system for Overpower, where the processor’s capabilities are largely left on the table. The measured frame rates across all resolutions and settings consistently reflect this bottleneck, making the Arc B390 the definitive limiting factor in this pairing.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 7500X3D is a 6-core, 12-thread processor from the 7000 series, built on the 5 nm process. It operates with a base clock of 4.00 GHz and a boost clock of 4.50 GHz, drawing a 65 W TDP. The processor features a substantial 96 MB of shared L3 cache, a hallmark of the X3D line, alongside 64 KB of L1 and 1 MB of L2 per core. This cache configuration is designed to benefit gaming workloads by reducing memory latency, but its impact here is masked by the GPU’s performance ceiling.

The CPU’s benchmark data shows it is a formidable part in isolation. It holds an 89th percentile ranking among all CPUs, with an average benchmark score of 44573. Its nearest rivals in synthetic testing include the Intel Core i9-13950HX (avgScore 44342, deltaPct 0.5) and the AMD Ryzen AI Max 385 (avgScore 44309, deltaPct 0.6), placing it just ahead of those parts. In contrast, it is 0.7% behind the Intel Core i5-14600 (avgScore 44889, deltaPct -0.7). These scores indicate that the Ryzen 5 7500X3D has ample processing headroom for a game like Overpower, with strong single-thread and multi-thread capabilities.

However, the measured game data tells a different story. At 1080p, the difference between Low and High settings yields only a 30 FPS spread (72 vs 42), which is modest. If the CPU were the limiting factor, we would expect to see frame rates plateau regardless of resolution, but that is not the case. The fact that FPS drops consistently as resolution increases points directly to the GPU being the primary constraint. The CPU’s role in this system is to feed frames as fast as the Arc B390 can render them, and it does so without breaking a sweat. The data suggests that the Ryzen 5 7500X3D is vastly overqualified for this GPU, and its performance potential is effectively untapped in this configuration.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, manufactured on Intel’s 3 nm process. It has a base clock of 300 MHz and a boost clock of 2500 MHz. Critically, its memory configuration is entirely system-shared, meaning it has no dedicated VRAM. The memory type, bus width, and bandwidth are all listed as "System Shared" or "System Dependent," which means it relies on the host system’s DDR5 memory. This is a fundamental limitation for gaming.

The GPU’s performance metrics confirm its low-end positioning. It holds a 9th percentile ranking among all GPUs, with a single benchmark score of 1482 in 3DMark Steel Nomad DX12. Its nearest rivals in that benchmark are all older, low-power NVIDIA parts: the GeForce GT 520MX (avgScore 1463, deltaPct 1.3), GeForce 800M (avgScore 1460, deltaPct 1.5), GeForce GT 625 OEM (avgScore 1446, deltaPct 2.5), and GeForce GT 710 (avgScore 1443, deltaPct 2.7). The Arc B390 is only 1.3% ahead of the GT 520MX, which is a decade-old entry-level mobile GPU. This context makes it clear that the Arc B390 is not designed for modern gaming at competitive frame rates.

In Overpower, the GPU’s limitations are immediately apparent. The highest measured average FPS is 72 at 1080p Low settings. At 1080p Ultra, this drops to 35 FPS. The GPU’s 1536 shading units and 24 ROPs are simply insufficient to handle the pixel fill rate and shading demands of higher settings and resolutions. The pixel rate is 60.00 GPixel/s, and the texture rate is 120.0 GTexel/s, but these are theoretical maximums that the shared memory bandwidth cannot sustain in practice. The result is a system that is entirely GPU-bound, where the Arc B390 is working at its absolute limit while the CPU idles.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The resolution scaling data is the clearest indicator of a GPU bottleneck. Looking at the Medium preset, which has the most complete data, the average FPS drops from 45 at 1920x1080, to 40 at 2560x1440, and finally to 34 at 3840x2160. This is a progressive degradation that correlates directly with the increase in pixel count. At 1080p, the GPU is managing 45 FPS, but at 4K, it falls to 34 FPS, a 24% reduction in performance. This pattern is consistent across all presets.

For the Low preset, the drop is from 72 FPS at 1080p to 64 FPS at 1440p, and then to 54 FPS at 4K. That is a 25% drop from 1080p to 4K. The High preset shows a similar trend: 42 FPS at 1080p, 37 FPS at 1440p, and 32 FPS at 4K. The Ultra preset follows suit with 35, 31, and 26 FPS respectively. These consistent, resolution-dependent declines are the hallmark of a GPU-limited scenario. If the CPU were the bottleneck, the frame rates would stay flat or even increase at lower resolutions where the CPU has less overhead, but we see the opposite.

The data strongly indicates that the limiting component is the GPU. A CPU bottleneck would manifest as similar FPS across different resolutions, because the CPU’s work per frame does not scale with resolution. Here, the FPS scales inversely with resolution, meaning the GPU’s rendering workload is the deciding factor. The Ryzen 5 7500X3D is likely capable of delivering far higher frame rates in Overpower, but it is capped by the Arc B390’s ability to output frames. This pairing is a textbook example of an extreme GPU bottleneck.

Settings Recommendations — which preset gives the best experience per the measured rows

Given the GPU’s constraints, the choice of settings is about finding a playable balance between visual quality and frame rate. The data shows that the Low preset is the only one that consistently breaks the 60 FPS threshold. At 1080p Low, the system averages 72 FPS. At 1440p Low, it drops to 64 FPS, which is still above 60. However, at 4K Low, it falls to 54 FPS, which is below the 60 FPS target but still playable on a standard 60 Hz display.

The Medium preset offers a slight visual improvement over Low but at a significant performance cost. At 1080p Medium, the average FPS is 45, which is a 37% drop from Low. The 1440p Medium setting yields 40 FPS, and 4K Medium yields 34 FPS. The High and Ultra presets are even more punishing. High settings at 1080p produce 42 FPS, while Ultra produces 35 FPS. These presets are not recommended for a smooth experience, as they fall well below the 60 FPS mark.

The best experience per the measured rows is unequivocally the Low preset at 1080p. It is the only configuration that provides a frame rate above 60 FPS, which is the baseline for smooth gameplay in an action title. If a user has a 1440p monitor, the Low preset at 1440p (64 FPS) is the next best option, as it remains above 60 FPS. The Medium preset at 1080p (45 FPS) could be acceptable for users who prioritize visuals over smoothness, but the data suggests that the performance hit is too steep for the marginal quality gain. For this combo, the recommendation is to stick with Low settings and prioritize frame rate, as the GPU does not have the headroom for higher presets.

How This Combo Ranks — use comboRankInGame vs other tested combos

The overall performance of this pairing is reflected in its ranking among all tested combinations in Overpower. The combo ranks 2638 out of 2980 total combos, placing it in the bottom 12% of all tested systems. This is a low rank, but it is entirely expected given the GPU’s capabilities. The rank of 2638 out of 2980 indicates that the vast majority of other CPU-GPU pairings in the database achieve higher frame rates in this game.

The ranking is not a reflection of the CPU’s quality but rather the GPU’s severe limitation. The Ryzen 5 7500X3D’s percentile rank of 89 suggests it would be a top-tier gaming CPU when paired with a discrete graphics card. However, when matched with the Arc B390, which has a percentile rank of 9, the system’s overall performance is dragged down to the bottom quartile. The data shows that this combo is heavily imbalanced. The CPU is in the top 11% of all processors, while the GPU is in the bottom 9% of all graphics cards.

This rank should be interpreted as a warning for anyone considering this pairing. The benchmark results indicate that the GPU will be the primary obstacle to achieving high frame rates in Overpower. The CPU’s potential is wasted in this configuration, and the combo rank of 2638 out of 2980 reflects that inefficiency. For a better experience, the data suggests that a different GPU would be necessary to unlock the Ryzen 5 7500X3D’s capabilities, as this pairing yields results that are far below what the CPU alone could support.
