Overpower

The AMD Ryzen 7 5700 paired with the Intel Arc B390 delivers a playable but constrained experience in Overpower, with benchmark data showing a system that is fundamentally limited by its graphics component. Across all tested resolutions and settings, the combo ranks 2638th out of 2980 tested configurations, placing it in the lower 12th percentile of all combos. The measured frame rates reveal a clear pattern: the Arc B390’s performance ceiling is reached well before the Ryzen 7 5700’s processing headroom is exhausted, making this a GPU-bound pairing in nearly every scenario.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and consistent across all settings, indicating that the Intel Arc B390 is the primary bottleneck. At Low settings, the average frame rate falls from 72 FPS at 1920x1080 to 64 FPS at 2560x1440, a reduction of 11.1%, and then to 54 FPS at 3840x2160, a further 15.6% drop from 1440p. This scaling pattern—where 1440p retains 88.9% of 1080p performance and 4K retains 75% of 1080p performance—shows a GPU that degrades predictably as pixel count increases, with no sudden cliff that would suggest a memory or bandwidth failure.

At Medium settings, the same trend holds but with slightly steeper drops. The average FPS moves from 45 at 1080p to 40 at 1440p (an 11.1% decrease) and then to 34 at 4K (a 15% decrease from 1440p). High settings tell a similar story: 42 FPS at 1080p, 37 at 1440p (11.9% down), and 32 at 4K (13.5% down from 1440p). The most telling data point is at Ultra settings, where the frame rate falls from 35 FPS at 1080p to 31 at 1440p (11.4% down) and then to 26 at 4K (16.1% down from 1440p). The slightly larger percentage drop at Ultra/4K suggests that the higher pixel count combined with heavier shading load pushes the Arc B390 closer to its raw compute limits.

The resolution scaling pattern points to a GPU that is bandwidth-constrained rather than core-limited. The Arc B390 uses System Shared memory, meaning its performance is tied to the system’s DDR4 bandwidth. As resolution increases, the demand for memory bandwidth grows faster than the demand for shading operations, which explains why the FPS drops are relatively linear but accelerate slightly at Ultra settings. If the CPU were the limiting factor, we would expect to see much smaller FPS deltas between 1080p and 4K, since higher resolutions offload work from the processor. Instead, the data shows a GPU that is consistently overwhelmed by pixel throughput, with the Ryzen 7 5700’s 8 cores and 16 threads sitting largely idle in wait.

GPU Role

The Intel Arc B390 is the defining component in this configuration, and its specifications explain the measured results. Built on Intel’s 3 nm process with the Xe3-LPG architecture, this integrated GPU runs at a base clock of 300 MHz and boosts to 2500 MHz. The 1536 shading units, 48 texture mapping units, and 24 raster output pipelines provide a theoretical pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. These figures translate to 7.680 TFLOPS of FP32 compute, which is modest by discrete GPU standards but respectable for an IGP.

The GPU’s percentile ranking of 9 versus all GPUs places it in the bottom 10% of graphics processors. Its nearest rivals in the benchmark database are all legacy 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). This clustering shows that the Arc B390 performs at roughly the level of a 2011-era entry-level discrete GPU, which aligns with the measured FPS in Overpower. The 3DMark Steel Nomad DX12 score of 1482 confirms this positioning, and the GPU’s average benchmark score of 1482 is identical, indicating that this single test dominates its profile.

The memory configuration is critical to understanding the performance ceiling. With System Shared memory, the Arc B390 has no dedicated VRAM, no dedicated memory bus width, and system-dependent bandwidth. This means the GPU competes with the CPU for DDR4 memory access, and the effective bandwidth is limited by the Ryzen 7 5700’s dual-channel configuration, which delivers 51.2 GB/s. In a game like Overpower, where texture streaming and framebuffer operations are memory-intensive, this shared arrangement creates a bottleneck that no amount of CPU headroom can overcome. The boost clock of 2500 MHz helps mitigate this somewhat, but the fundamental lack of dedicated memory bandwidth caps the GPU’s ability to feed its 1536 shading units efficiently.

Measured FPS Breakdown

At 1920x1080, the configuration shows its best performance across all settings. Low settings produce an average of 72 FPS, which is the only measured result that reaches the 60 FPS threshold typically considered smooth for action games. Medium settings average 45 FPS, with a minimum of 38 and maximum of 52 FPS, indicating some frame pacing variability. High settings average 42 FPS, and Ultra settings average 35 FPS. The spread between Low and Ultra is 37 FPS, showing that settings have a significant impact at this resolution.

Moving to 2560x1440, the performance drops across the board. Low settings average 64 FPS, which remains playable but shows an 11.1% reduction from 1080p. Medium settings average 40 FPS, with a minimum of 34 and maximum of 46 FPS. High settings average 37 FPS, and Ultra settings average 31 FPS. The gap between Low and Ultra narrows to 33 FPS at this resolution, suggesting that the GPU’s compute resources are becoming more saturated as pixel count increases.

At 3840x2160, the Arc B390 struggles to maintain playable frame rates. Low settings average 54 FPS, which is borderline for action gameplay. Medium settings average 34 FPS, with a minimum of 29 and maximum of 39 FPS, showing that the GPU is hitting its limits. High settings average 32 FPS, and Ultra settings average 26 FPS. The 4K Ultra result is the lowest measured score in the entire dataset, representing a 63.9% reduction from the 1080p Low result. The Medium settings at 4K show a 9-FPS spread between minimum and maximum, indicating significant frame time variance under load.

The data reveals a consistent pattern: each settings tier at a given resolution costs roughly 5-8 FPS, and each resolution step costs roughly 5-10 FPS at the same settings. This linear degradation is characteristic of a GPU that is compute-bound rather than bandwidth-bound, as the Arc B390’s 7.680 TFLOPS of FP32 throughput is simply insufficient for higher pixel counts and detail levels.

How This Combo Ranks

The combination of the AMD Ryzen 7 5700 and Intel Arc B390 ranks 2638th out of 2980 tested combinations in Overpower. This places the combo in the bottom 11.5% of all systems tested for this game, which is directly attributable to the GPU’s low performance ceiling. The CPU’s percentile ranking of 78 versus all CPUs is in stark contrast to the GPU’s 9th percentile ranking, creating a significant performance imbalance.

The Ryzen 7 5700’s nearest CPU rivals in the database are the Intel Xeon D-2752TER (0.1% slower), AMD Ryzen 5 7640U (0.1% faster), AMD Ryzen 5 6600H (0.1% slower), and AMD Ryzen 7 5825U (0.3% faster). These are all tightly clustered around the same average benchmark score of approximately 25,500, confirming that the CPU is a mid-to-high-tier performer. The Arc B390’s nearest GPU rivals, by contrast, are all significantly older and weaker parts, reinforcing the notion that this GPU is the weak link.

The combo rank of 2638 is not surprising given the GPU’s 9th percentile standing. Even with a strong CPU like the Ryzen 7 5700, the overall system performance is dragged down by the Arc B390’s inability to keep up with the game’s rendering demands. The delta between the CPU’s percentile (78th) and the combo’s percentile (88.5th from the bottom) highlights how severely the GPU limits the system. In games that are less GPU-intensive, this combo would likely rank higher, but Overpower’s action-oriented rendering clearly favors discrete GPUs with dedicated memory.

CPU Role

The AMD Ryzen 7 5700 provides ample processing power for Overpower, though the game’s frame rates never come close to stressing it. With 8 cores and 16 threads based on the Zen 3 architecture (Cezanne codename), this CPU runs at a base clock of 3.70 GHz and boosts to 4.60 GHz. The 7 nm process from TSMC packs 10,700 million transistors into a 180 mm² die, and the 16 MB of L3 cache (in addition to 512 KB L2 per core and 64 KB L1 per core) provides solid memory hierarchy for game logic and physics.

The CPU’s benchmark scores show strong multi-threaded performance: a Cinebench R23 multi-core score of 20655 and a single-core score of 2916. The 3DMark results are equally telling, with 16-thread performance at 6628, 8-thread at 5585, 4-thread at 3382, and 2-thread at 1762. The single-thread 3DMark score of 901 indicates that even lightly threaded workloads are handled efficiently. Geekbench scores of 9959 multi-core and 1907 single-core, along with a Passmark multi-thread score of 24303, confirm this is a capable processor for gaming.

In Overpower, the CPU is never the bottleneck. The highest measured frame rate is 72 FPS at 1080p Low, which is well within the Ryzen 7 5700’s capability. Even at 4K Ultra with 26 FPS, the CPU has significant headroom, as evidenced by its 65 W TDP and 51.2 GB/s memory bandwidth. The dual-channel DDR4 support at these speeds is sufficient for the game’s data streaming needs, and the CPU’s PCIe Gen 3 interface (20 lanes) is not a limiting factor since the Arc B390 uses system shared memory rather than dedicated PCIe bandwidth.

The CPU’s nearest rivals in the database—the Xeon D-2752TER, Ryzen 5 7640U, Ryzen 5 6600H, and Ryzen 7 5825U—are all within 0.3% of its average benchmark score of 25517. This grouping shows that the Ryzen 7 5700 is a solid mid-range performer, but its potential is wasted in this configuration because the GPU cannot translate CPU horsepower into higher frame rates. The 3DMark max threads score of 6617 versus the 16-thread score of 6628 shows negligible scaling beyond 16 threads, confirming the game is not CPU-bound.

Settings Recommendations

For the best experience with this combo, the data supports prioritizing resolution over settings. At 1920x1080 Low, the system achieves 72 FPS, which is the only setting that provides a smooth, consistent frame rate above 60 FPS. This is the recommended configuration for action gameplay, as it ensures the game remains responsive during fast-paced sequences. The Medium setting at 1080p yields 45 FPS, which is playable but may introduce noticeable stutter during intense scenes, especially given the 38-52 FPS range.

If visual quality is a priority, 1080p High at 42 FPS is a reasonable compromise, offering better graphics while maintaining a playable frame rate. The Ultra setting at 1080p drops to 35 FPS, which is below the threshold for smooth action gameplay and should be avoided. At 2560x1440, Low settings at 64 FPS are the only playable option, while Medium at 40 FPS is borderline. High and Ultra at 1440p (37 and 31 FPS respectively) are not recommended for gameplay.

At 3840x2160, only Low settings at 54 FPS approach playability, and even this is marginal. Medium at 34 FPS, High at 32 FPS, and Ultra at 26 FPS are all too slow for an action game. Given the measured data, the optimal configuration is 1920x1080 with Low settings, which maximizes frame rate and minimizes the risk of frame pacing issues. The 4K resolution should be reserved for static scenes or screenshots, as the frame rates are insufficient for interactive use. The measured minimum FPS values at Medium settings (29 at 4K, 34 at 1440p, 38 at 1080p) suggest that the GPU can cause noticeable hitches when the action intensifies, further reinforcing the recommendation to use Low settings at 1080p for the most consistent experience.
