Overpower

The Intel Core Ultra 7 265K paired with the Intel Arc B390 (integrated graphics) is a configuration defined by extreme asymmetry. The CPU is a 20-core desktop flagship, while the GPU is an integrated solution with system-shared memory. Benchmark data for Overpower shows this combo ranking 2638 out of 2980 tested combinations, placing it in the bottom 11.7% of systems. This page analyzes the measured FPS across resolutions and settings, breaking down what the data reveals about the limiting components.

Resolution Scaling

The measured frames per second (FPS) for this combo in Overpower show a clear and consistent drop as resolution increases, but the magnitude of the drop is modest compared to what a discrete GPU would typically exhibit. At High settings, the average FPS falls from 42 at 1920x1080 to 37 at 2560x1440, and then to 32 at 3840x2160. This represents a degradation of 11.9% from 1080p to 1440p, and a further 13.5% from 1440p to 4K, for a total drop of 23.8% from the lowest to the highest resolution.

The relatively small performance penalty from resolution scaling is a strong indicator that the system is severely bottlenecked by the GPU at all resolutions. When a GPU is the primary constraint, increasing pixel count usually causes a dramatic FPS reduction. Here, the reduction is relatively linear and shallow, meaning the Intel Arc B390 is already operating at its performance ceiling even at 1080p, and the additional pixel workload at higher resolutions does not proportionally increase the bottleneck because the GPU is already saturated.

Looking at Low settings, the same pattern emerges. FPS averages 72 at 1080p, drops to 64 at 1440p (an 11.1% reduction), and then to 54 at 4K (a 15.6% reduction from 1440p). The fact that the delta remains in the 11-15% range across settings and resolutions suggests that the integrated GPU's compute and fillrate limits, rather than memory bandwidth or CPU processing, are dominating the frame rate. If the CPU were the bottleneck, we would expect to see a plateau in FPS at lower resolutions, where the GPU has less work to do; the data shows no such plateau.

The data suggests that the Intel Core Ultra 7 265K is not the limiting factor in this configuration for Overpower. At 1080p Low, the system achieves 72 FPS, but this is still a low absolute number for a modern action game, even with a top-tier CPU. If the CPU were limiting, we would expect to see similar FPS across all resolutions at Low settings. Instead, the FPS scales downward consistently, indicating the GPU is the sole constraint. The shallow scaling curve implies that users upgrading from 1080p to 1440p or 4K will experience a noticeable but not catastrophic performance loss, which is atypical for discrete GPU configurations.

GPU Role

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture and built on a 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. Critically, its memory is "System Shared," meaning it uses a portion of the main system DDR5 memory rather than dedicated VRAM. Its bandwidth is listed as "System Dependent," and its memory bus width is also "System Shared," which is a fundamental limitation for gaming performance.

In Overpower, the GPU's role is the primary performance limiter. The 3DMark Steel Nomad DX12 benchmark score for the B390 is 1482, which places it in the 9th percentile of all GPUs. Its nearest rivals are all legacy NVIDIA parts, including the GeForce GT 520MX (score 1463, 1.3% slower), the GeForce 800M (score 1460, 1.5% slower), and the GeForce GT 625 OEM (score 1446, 2.5% slower). This indicates the B390's raw rendering performance is comparable to entry-level discrete GPUs from over a decade ago.

The measured FPS in Overpower reflects this low standing. At 3840x2160 Ultra settings, the combo averages only 26 FPS, which is below playable thresholds for an action game. Even at 1080p Low, the average is 72 FPS, which is acceptable but far from high-refresh-rate territory. The GPU's clock speeds of 300 MHz base and 2500 MHz boost do not compensate for the lack of dedicated memory bandwidth. The system-shared memory architecture means the GPU contends with the CPU for memory access, which is a severe bottleneck in a game like Overpower that likely requires frequent texture streaming.

The 12 ray tracing cores and 1536 shading units are present, but the data shows they do not deliver playable performance at higher settings. The 24 ROPs and 48 TMUs give a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s, but these figures are insufficient for 4K Ultra rendering in this title. The FP32 performance is rated at 7.680 TFLOPS, yet the benchmark results show that this theoretical compute capability is not translating into practical frame rates. The GPU's percentile rank of 9 versus all GPUs is a stark indicator that this is a very low-performance part, and the measured FPS in Overpower confirms this analysis.

How This Combo Ranks

In the database of tested combinations for Overpower, the Intel Core Ultra 7 265K + Intel Arc B390 combo ranks 2638 out of 2980 configurations. This places it in the bottom 11.5% of all tested systems, which is a poor result for a CPU that is in the 94th percentile of all processors. The combo's rank is a direct consequence of the GPU's limitations, as the CPU's high benchmark scores are not able to manifest in gaming performance when paired with such a weak integrated graphics solution.

The CPU itself performs well in synthetic benchmarks. It scores 35850 in Cinebench R23 multi-core and 2020 in single-core. Its average benchmark score is 70879, which is comparable to the Intel Xeon 6511P (71051, 0.2% higher) and the Intel Xeon Platinum 8270 (71370, 0.7% higher). It is also 1% ahead of the Intel Core i7-14700KF and 1.3% ahead of the AMD Ryzen 7 9700F. However, these CPU strengths are entirely irrelevant to the gaming frame rate when the GPU is this slow. The combo rank of 2638 reflects the total system performance, and the B390 drags the entire configuration down to near the bottom of the chart.

The data shows a massive disconnect between the CPU's capabilities and the system's gaming performance. While the CPU is performing at a high level relative to its rivals, the GPU is performing at a level comparable to the NVIDIA GeForce GT 520MX, which is a 1.3% difference in 3DMark score. This means the system is effectively GPU-bound in all scenarios. The combo rank is a clear indicator that this pairing is not suitable for gaming at any of the tested settings, as even the best-case scenario of 72 FPS at 1080p Low places it far behind the median system.

Measured FPS Breakdown

The measured data provides a full grid of results across three resolutions and four settings presets. The following table summarizes the average FPS for each combination:

• 1920x1080: Low 72 FPS, Medium 45 FPS, High 42 FPS, Ultra 35 FPS.
• 2560x1440: Low 64 FPS, Medium 40 FPS, High 37 FPS, Ultra 31 FPS.
• 3840x2160: Low 54 FPS, Medium 34 FPS, High 32 FPS, Ultra 26 FPS.

At 1080p Low, the system achieves its highest average of 72 FPS. This is the only configuration that approaches a comfortable playable frame rate for a fast-paced action game. Moving to Medium settings at 1080p drops the average to 45 FPS, which is a 37.5% reduction from Low. High settings yield 42 FPS, and Ultra drops to 35 FPS. The gap between Low and Medium is substantial, suggesting that Medium settings introduce significantly more GPU workload (likely shading and texture effects) than Low.

At 1440p, the frame rates are consistently lower. Low averages 64 FPS, which is still respectable, but Medium drops to 40 FPS and High to 37 FPS. Ultra at 1440p averages 31 FPS, which is below the 30 FPS threshold that many consider the absolute minimum for acceptable gameplay. The pattern holds at 4K, where even Low settings only achieve 54 FPS. Medium at 4K averages 34 FPS, High 32 FPS, and Ultra 26 FPS. The 4K Ultra result of 26 FPS is the worst measured, and it indicates that this combo is not viable for 4K gaming at high fidelity.

The min and max FPS values are only provided for Medium settings. At 1080p Medium, the range is 38 to 52 FPS. At 1440p Medium, the range is 34 to 46 FPS. At 4K Medium, the range is 29 to 39 FPS. These ranges show a spread of roughly 10-14 FPS, indicating some frame time variance, but not a severe stuttering problem. The absence of min/max data for other presets suggests that the average values are the primary metric for comparison, and the consistent step-down in averages across presets confirms the GPU bottleneck.

CPU Role

The Intel Core Ultra 7 265K is a 20-core, 20-thread processor based on the Arrow Lake architecture. It has a base clock of 3.90 GHz and a boost clock of 5.50 GHz. It includes 30 MB of shared L3 cache and supports DDR5 memory. Its performance is exceptional in synthetic benchmarks, scoring 35850 in Cinebench R23 multi-core and 2020 in single-core. It ranks in the 94th percentile of all CPUs, and its average benchmark score of 70879 puts it in the same tier as server-class Xeon processors.

However, in Overpower, the CPU's role is minimal due to the GPU bottleneck. The data shows that the FPS is consistently low across all resolutions, which would not be the case if the CPU were the limiting factor. A powerful CPU like the 265K would be able to maintain high frame rates at 1080p if paired with a capable GPU. Here, the FPS drops from 72 at 1080p Low to 54 at 4K Low, proving that the CPU is not the constraint. The CPU's 20 cores and 20 threads are more than sufficient for this game, and its high boost clock of 5.50 GHz ensures that single-threaded performance is not an issue.

The CPU's memory bandwidth of 102.4 GB/s is also not a bottleneck in this scenario, as the GPU is using system memory and is likely the primary consumer of bandwidth. The CPU's benchmark scores indicate it is operating at a high level, but this performance is wasted in this configuration. The nearest CPU rivals, such as the Intel Xeon 6511P (0.2% faster) and the Core i7-14700KF (1% slower), would likely produce identical FPS in Overpower when paired with the same B390 GPU, because the system is entirely GPU-limited. The CPU's role is to feed the GPU, and it does so without breaking a sweat, but the GPU cannot translate that feed into high frame rates.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the user's target resolution and tolerance for frame rate. For a playable experience at 1920x1080, Low settings are the only viable choice, yielding 72 FPS average. This is smooth enough for most action games. Medium settings at 1080p drop to 45 FPS, which is still playable but may feel less fluid during intense combat. High and Ultra at 1080p (42 and 35 FPS) are borderline, with Ultra approaching the edge of unplayability.

At 2560x1440, the situation is more constrained. Low settings average 64 FPS, which is acceptable. Medium settings average 40 FPS, which is on the low side for a competitive action title. High and Ultra at 1440p (37 and 31 FPS) are not recommended for a smooth experience, as frame rates below 35 FPS can feel choppy. For 3840x2160, only Low settings (54 FPS) are remotely playable. Medium at 34 FPS is just at the edge of acceptable, while High (32 FPS) and Ultra (26 FPS) are too slow for reliable gameplay.

The analysis suggests that the best experience is achieved at 1080p with Low settings. This provides the highest average FPS of 72 and avoids the frame rate drops seen at higher resolutions. If the user prioritizes visual quality over frame rate, Medium settings at 1080p (45 FPS) are a reasonable compromise. However, the data indicates that this combo cannot maintain high frame rates at higher quality presets without significant performance degradation. For users with a 1440p or 4K display, the recommendation is to run at Low settings and accept the lower visual fidelity, as the GPU lacks the bandwidth and compute power to handle higher presets at those resolutions. The system is not capable of a consistent 60 FPS experience at any resolution above 1080p, so the best course of action is to prioritize frame rate at 1080p Low.
