Overpower

The Overpower combination of the Intel Core i5-10400F and the Intel Arc B390 produces a playable but constrained experience, heavily dependent on resolution and settings. The data indicates that this combo is best suited for 1080p gaming, where it achieves acceptable frame rates, while higher resolutions push the system into a GPU-bound state that severely limits performance. The overall ranking is low, placing this pairing in the bottom tier of tested configurations.

Resolution Scaling

The performance drop from 1080p to 4K is significant and reveals a clear bottleneck. At 1080p with Low settings, the combo delivers 72 FPS. Moving to 1440p at the same settings reduces the average to 64 FPS, a decrease of 8 FPS. Scaling further to 4K Low drops the average to 54 FPS, representing a 10 FPS loss from the 1440p figure. This pattern indicates that the GPU is the primary limiting factor, as the frame rate decreases consistently with each increase in pixel count.

The scaling becomes more pronounced at higher settings. At Medium settings, the average frame rate falls from 45 FPS at 1080p to 40 FPS at 1440p, and then to 34 FPS at 4K. The High preset shows a similar trend: 42 FPS at 1080p, 37 FPS at 1440p, and 32 FPS at 4K. The Ultra preset produces the lowest results, with 35 FPS at 1080p, 31 FPS at 1440p, and 26 FPS at 4K. Across all settings, the gap between 1080p and 4K is roughly 15-18 FPS, which is substantial for a game of this genre.

The data suggests that the Arc B390's rendering capabilities are overwhelmed by the 4K resolution. The percentage difference between 1080p and 4K is largest at the Low preset, where the 72 FPS at 1080p drops to 54 FPS at 4K, a 25% reduction. This is a strong indicator that the GPU's compute units and memory bandwidth are saturated at higher resolutions. The CPU, with its 6 cores and 12 threads, appears capable of feeding the GPU at 1080p, but as resolution increases, the GPU's workload grows and becomes the definitive constraint on performance.

How This Combo Ranks

In the benchmark database, this specific combination of the Intel Core i5-10400F and the Intel Arc B390 ranks 2638 out of 2980 tested combos for Overpower. This places it in the bottom 12% of all tested systems, indicating that it is a low-performing pairing for this title. The rank is a composite measure that reflects the overall capability of the CPU and GPU working together in this game.

The low ranking is driven primarily by the GPU's performance. The Arc B390 sits at the 9th percentile of all GPUs in the database, meaning 91% of tested graphics cards deliver better average benchmark scores. Its average benchmark score is 1482, which is notably lower than the scores achieved by the CPU in the same system. This disparity highlights that the GPU is the weak link in this configuration for gaming workloads. The CPU, while not a top performer, is far more capable relative to its peers than the GPU is.

The combo's ranking is a direct consequence of the GPU's limited power. Even with a mid-range CPU like the i5-10400F, the overall system performance is dragged down by the Arc B390's inability to sustain high frame rates in Overpower. The data shows that this pairing is not competitive with other tested combos, and users seeking a smoother experience would need to consider a different GPU or a lower resolution target.

GPU Role

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, built on a 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The GPU has 1536 shading units, 48 texture mapping units, and 24 raster output units, along with 12 ray tracing cores. Its peak pixel rate is 60.00 GPixel/s and texture rate is 120.0 GTexel/s, with FP32 performance rated at 7.680 TFLOPS.

The memory configuration is "System Shared," meaning the GPU uses a portion of the main system memory rather than dedicated VRAM. The memory bus width and bandwidth are listed as "System Shared" and "System Dependent," respectively. This is a critical detail, as shared memory can lead to bandwidth contention and lower effective performance compared to dedicated graphics memory. The GPU's TDP is 80 W, and it is classified as an IGP (Integrated Graphics Processor) with no power connectors required.

In Overpower, the GPU's limitations are evident in the measured FPS. The benchmark results show that the Arc B390 struggles to maintain smooth frame rates even at 1080p with higher settings. The GPU's percentile rank of 9 versus all other GPUs confirms its position at the very low end of the performance spectrum. Its nearest rivals in the database are older, low-end discrete GPUs such as the NVIDIA GeForce GT 520MX and the GeForce GT 710, which it outperforms by a small margin. This context underscores that the Arc B390 is not designed for demanding gaming workloads.

The boost clock of 2500 MHz is relatively high for an integrated solution, but the limited number of shading units and the shared memory architecture prevent it from translating into competitive gaming performance. The data indicates that the GPU becomes the bottleneck at 1440p and 4K, where the frame rates drop below playable thresholds for most users.

Measured FPS Breakdown

The measured performance data provides a detailed view of the combo's capabilities across different resolutions and settings. At 1920x1080, the system achieves its best results. With Low settings, the average frame rate is 72 FPS, which is smooth and responsive. Medium settings produce 45 FPS on average, with a minimum of 38 FPS and a maximum of 52 FPS. High settings yield 42 FPS on average, and Ultra settings drop to 35 FPS on average. These figures show that 1080p is the only resolution where the combo can deliver a consistently playable experience, particularly at Low settings.

At 2560x1440, performance decreases across the board. Low settings average 64 FPS, which remains acceptable, but Medium settings fall to 40 FPS (minimum 34 FPS, maximum 46 FPS). High settings average 37 FPS, and Ultra settings average 31 FPS. The drop from 1080p to 1440p is noticeable, and the frame rates at High and Ultra settings approach the lower edge of what is considered playable for an action game.

At 3840x2160, the system is severely challenged. Low settings average 54 FPS, which is the only setting at this resolution that approaches playability. Medium settings average 34 FPS with a minimum of 29 FPS and a maximum of 39 FPS, while High settings average 32 FPS. Ultra settings produce an average of just 26 FPS, which is too low for a smooth gaming experience. The data shows that 4K is not a viable resolution for this combination in Overpower, regardless of the settings used.

The minimum frame rate data for the Medium settings provides insight into frame pacing. At 4K Medium, the minimum FPS is 29, which is a significant drop from the average of 34 FPS. Similarly, at 1440p Medium, the minimum is 34 FPS versus an average of 40 FPS. These dips indicate that the GPU can stutter during demanding scenes, which can negatively affect the gaming experience even when the average frame rate seems acceptable.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture, built on a 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz. The CPU features 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 12 MB of shared L3 cache. It supports dual-channel DDR4 memory with a bandwidth of 42.7 GB/s and uses PCIe Gen 3 with 16 lanes.

In terms of CPU benchmarks, the i5-10400F performs adequately. Its Cinebench R23 multicore score is 10283, and its single-core score is 1451. The Geekbench multicore score is 6257, with a single-core score of 1420. The Passmark multithread score is 12115, and the single-thread score is 2541. These scores place the CPU at the 68th percentile of all CPUs in the database, indicating that it is a solid mid-range processor.

The CPU's role in Overpower is to feed the GPU with data and handle game logic. Given the benchmark results, the i5-10400F appears to be sufficiently powerful for this task. The data shows that at 1080p Low settings, the system can achieve 72 FPS, which suggests that the CPU is not a limiting factor at this resolution. However, the CPU's performance becomes less relevant as resolution increases, because the GPU's workload grows and becomes the dominant constraint.

The nearest rivals to the i5-10400F in the database include the Intel Xeon 6756E, which scores 0.2% higher, and the AMD Ryzen 3 7320C, which scores 0.6% lower. These small deltas show that the CPU is competitive with other processors in its performance class. For Overpower, the CPU's 6 cores and 12 threads are likely sufficient to handle the game's demands, as the bottleneck is clearly on the GPU side.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combination in Overpower depend on the user's resolution and performance preferences. At 1920x1080, the Low preset is the clear best choice for a smooth experience, delivering an average of 72 FPS. This is the only setting at any resolution that breaks the 70 FPS barrier, providing a responsive and fluid gameplay experience. The Medium preset, at 45 FPS, is a playable alternative for users who want better visuals but are willing to accept a lower frame rate.

At 2560x1440, the Low preset is again the recommended choice, with an average of 64 FPS. This is a significant step down from 1080p but remains within the playable range. The Medium preset at 40 FPS is borderline, and the High and Ultra presets at 37 and 31 FPS respectively are likely to feel less smooth, especially in fast-paced action sequences.

At 3840x2160, the data suggests that this resolution should be avoided unless the user is willing to accept very low performance. The Low preset averages 54 FPS, which is the only playable option, but the visual quality will be significantly reduced. The Medium preset at 34 FPS and High at 32 FPS are marginal, and Ultra at 26 FPS is not recommended for a playable experience.

The analysis indicates that the best overall experience is achieved at 1080p with Low settings, which provides the highest frame rate and most consistent performance. For users who prioritize visual quality over frame rate, the Medium preset at 1080p offers a balanced compromise, with an average of 45 FPS and a minimum of 38 FPS. The data clearly shows that the Arc B390 is not capable of delivering high frame rates at higher resolutions or settings, so users should tailor their expectations accordingly.
