Overpower

The Intel Core i5-12400F and Intel Arc B390 combination lands near the bottom of the tested field for Overpower, ranking 2638 out of 2980 combos. That places it in the 12th percentile of all tested configurations, which means roughly nine out of every ten rival setups deliver higher average frame rates in this title. The pairing of a capable mainstream six-core processor with an integrated-class graphics solution produces playable but modest results, and the data indicates that the GPU is the dominant constraint across every resolution and settings preset tested.

How This Combo Ranks

The combo’s rank of 2638 out of 2980 tested combos is a clear signal that this is not a high-performance gaming configuration for Overpower. With only 342 combos ranked below it, this setup sits in the lower tier of what the benchmark database has recorded for this game. The percentile placement of roughly 11.5% means the vast majority of other CPU-GPU pairings achieve higher average FPS. This is not a surprise given the components involved: the Arc B390 is an integrated GPU (IGP) with a modest 3DMark Steel Nomad DX12 score of 1482, which places it in the 9th percentile of all GPUs tested.

Looking at the GPU’s nearest rivals in the database, the Arc B390 sits only 1.3% ahead of the NVIDIA GeForce GT 520MX, 1.5% ahead of the GeForce 800M, 2.5% ahead of the GT 625 OEM, and 2.7% ahead of the GT 710. These are all very old, low-end discrete graphics parts, which underscores how limited the Arc B390’s raw rendering power is for a modern action game like Overpower. The CPU, meanwhile, is a much stronger performer relative to its own field. The i5-12400F holds a 73rd percentile ranking among all CPUs, with an average benchmark score of 19039. Its nearest rivals include the AMD Ryzen 5 7535HS (deltaPct 0), Intel Core 3 201E (deltaPct -0.1), Intel Core i5-1335U (deltaPct 0.3), and AMD EPYC 7773X (deltaPct 0.3). All of these are within a fraction of a percent of the i5-12400F’s average score, meaning the CPU is essentially on par with those parts in general compute workloads. The bottleneck in this combo is unmistakably the GPU, as the measured FPS data will show.

GPU Role

The Intel Arc B390 is built on the Xe3-LPG architecture, specifically the Panther Lake chip, fabricated on a 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The memory configuration is entirely system-shared, with no dedicated VRAM; the size, type, and bus width are all listed as “System Shared,” and bandwidth is “System Dependent.” This means the GPU relies on the CPU’s memory subsystem, which for the i5-12400F is dual-channel DDR4 or DDR5. The practical effect in Overpower is that the GPU has no dedicated high-bandwidth memory pool, which limits texture fill and frame buffer performance.

The shading units number 1536, with 48 texture mapping units and 24 raster output units. It also includes 12 ray tracing cores. The pixel rate is 60.00 GPixel/s, and the texture rate is 120.0 GTexel/s. Floating-point performance is 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16 (2:1). The GPU’s TDP is 80 W, and it is classified as an IGP with no power connectors and a bus interface of IGP. Display outputs are listed as “Portable Device Dependent,” which suggests this is intended for mobile or compact systems. In terms of API support, it handles DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so it is modern in feature support even if raw throughput is low.

The GPU’s only recorded benchmark is the 3DMark Steel Nomad DX12 test, where it scored 1482. That score places it at the 9th percentile of all GPUs, meaning 91% of tested graphics cards perform better in that synthetic workload. The nearest rivals are all NVIDIA parts from over a decade ago: GT 520MX (1463, deltaPct 1.3), GeForce 800M (1460, deltaPct 1.5), GT 625 OEM (1446, deltaPct 2.5), and GT 710 (1443, deltaPct 2.7). The fact that the Arc B390 only narrowly edges out these legacy parts in a DX12 test indicates that its real-world gaming performance will be severely constrained. In Overpower, this translates into average FPS figures that are playable only at lower settings and resolutions, as the measured data confirms.

Resolution Scaling

Examining the measured FPS across resolutions reveals a clear pattern: the GPU is the limiting factor at every step, but the scaling behavior shows that even dropping resolution does not unlock high frame rates. At 1920x1080 with Low settings, the combo achieves 72 FPS average. Moving to 2560x1440 Low drops that to 64 FPS, a reduction of 8 FPS or roughly 11.1%. At 3840x2160 Low, the average falls to 54 FPS, another 10 FPS drop from 1440p, or about 15.6% lower. This scaling is relatively mild compared to what a discrete GPU would show, because the system-shared memory and low fill rate create a bottleneck that persists even at lower pixel counts.

For Medium settings, the pattern is similar but with lower absolute numbers. At 1080p Medium, the average is 45 FPS. At 1440p Medium, it drops to 40 FPS, a 5 FPS reduction (11.1%). At 4K Medium, it falls to 34 FPS, another 6 FPS drop (15%). The High settings show 42 FPS at 1080p, 37 FPS at 1440p, and 32 FPS at 4K. The delta from 1080p to 4K for High is 10 FPS, or about 23.8% lower. Ultra settings yield 35 FPS at 1080p, 31 FPS at 1440p, and 26 FPS at 4K. The drop from 1080p to 4K on Ultra is 9 FPS, or 25.7%.

The resolution scaling data suggests that the GPU’s performance is not purely pixel-bound. If the GPU were completely fill-rate limited, the FPS would scale more dramatically with resolution. Instead, the relatively modest drops (roughly 10-25% from 1080p to 4K depending on settings) indicate that other factors—such as driver overhead, memory bandwidth from system RAM, and the CPU’s role in feeding the GPU—are also at play. The i5-12400F has a 3DMark 16-thread score of 5895 and a single-thread score of 909, which are not limiting for a game at these low frame rates. The CPU is likely waiting on the GPU, but the GPU’s system-shared memory creates a latency and bandwidth ceiling that prevents it from scaling efficiently with resolution changes.

Measured FPS Breakdown

The measured FPS data provides a complete picture of what this combo can deliver in Overpower. Starting at 1920x1080, the lowest preset (Low) produces an average of 72 FPS. This is the only configuration in the entire dataset that crosses the 60 FPS threshold, making it the sole clearly smooth experience. Medium settings at 1080p drop to 45 FPS average, with a minimum of 38 FPS and a maximum of 52 FPS. That minimum is below the 60 FPS target but still within a range that many players would find acceptable for a slower-paced action title. High settings at 1080p yield 42 FPS average, with no min/max recorded. Ultra settings at 1080p produce 35 FPS average, which is noticeably less fluid.

Moving to 2560x1440, the numbers decline across the board. Low settings average 64 FPS, which is still above 60 and represents the second-highest measured result overall. Medium settings at 1440p average 40 FPS, with a minimum of 34 FPS and a maximum of 46 FPS. High settings average 37 FPS, and Ultra averages 31 FPS. None of these 1440p presets except Low achieve a consistently smooth experience, and the Ultra result at 31 FPS is approaching the lower boundary of playability for an action game.

At 3840x2160, the results are marginal. Low settings average 54 FPS, which is technically playable but with noticeable dips possible. Medium settings average 34 FPS, with a minimum of 29 FPS and a maximum of 39 FPS—the 29 FPS minimum suggests occasional stutter. High settings average 32 FPS, and Ultra averages 26 FPS. The 4K Ultra result is the worst in the dataset, and even the best 4K result (Low at 54 FPS) is not smooth enough for competitive play. Across all twelve measured configurations, the spread from best to worst is 72 FPS (1080p Low) to 26 FPS (4K Ultra), a range of 46 FPS. The data shows a consistent pattern: each settings tier costs roughly 7-10 FPS at a given resolution, and each resolution step costs roughly 5-10 FPS at a given settings tier.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo is clearly at 1920x1080 with Low settings, which delivers 72 FPS average. This is the only preset that provides a comfortable margin above 60 FPS, and for an action game like Overpower, that headroom is valuable for maintaining responsiveness during combat. The next best option is 2560x1440 Low at 64 FPS, which is also above 60 but comes with a higher pixel count that may cause more frequent dips if the scene complexity increases. If a player values resolution over frame rate, 1440p Low is acceptable, but 1080p Low is the safer choice for consistent smoothness.

For players who want better visual quality, the Medium preset at 1080p (45 FPS average, 38 FPS minimum) is the highest settings tier that remains within a playable range. The 38 FPS minimum is low but not catastrophic, and the average of 45 FPS is workable for a single-player action title. High settings at 1080p (42 FPS) and Medium at 1440p (40 FPS) are similar in average performance, but the 1440p Medium has a lower minimum (34 FPS) which could cause more noticeable hitches. Ultra settings should be avoided entirely; the best Ultra result is 35 FPS at 1080p, and it degrades to 26 FPS at 4K. The visual uplift from Ultra over High or Medium is not worth the frame rate penalty given the GPU’s limited resources.

The data suggests that the i5-12400F is not the limiting factor in any of these configurations. The CPU’s Cinebench R23 multicore score of 12380 and single-core score of 1680 indicate plenty of headroom for a game that is clearly GPU-bound at these frame rates. Even at 1080p Low, where the GPU is working hardest to hit 72 FPS, the CPU is unlikely to be the bottleneck. The recommendation is to prioritize frame rate over resolution or settings: 1080p Low for competitive smoothness, 1080p Medium for a balanced experience, and 1440p Low only if the display requires a higher native resolution. Anything above Medium at 1080p, or any preset above Low at 1440p, will result in average FPS below 45 and minimums that can dip into the low 30s.

CPU Role

The Intel Core i5-12400F is a 6-core, 12-thread processor from the Core 12th Gen series, based on the Alder Lake architecture with a 10 nm process node. It has a base clock of 2.50 GHz and a boost clock of 4.40 GHz, with a 65 W TDP. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. It supports DDR4 and DDR5 memory in a dual-channel configuration, with PCIe Gen 5 providing 20 lanes from the CPU. The launch MSRP is $174, and it has a production status of Active.

In terms of CPU benchmarks, the i5-12400F shows strong single-thread and multi-thread performance for its class. Its 3DMark scores are 5895 for 16 threads, 1699 for 2 threads, 3067 for 4 threads, 4779 for 8 threads, 5912 for max threads, and 909 for single thread. Cinebench R23 results are 12380 multicore and 1680 single-core. Geekbench scores are 9472 multicore and 1964 single-core. PassMark results include 19433 multithread and 3481 single-thread. The CPU’s percentile ranking is 73, meaning it outperforms 73% of all CPUs in the database. Its nearest rivals are all within 0.3% of its average score, confirming that the i5-12400F sits in a tightly contested performance band.

In the context of Overpower, the CPU’s role is to feed the GPU with draw calls, physics calculations, and game logic. Given the measured FPS range of 26 to 72, the CPU is never the limiting component. Even at 1080p Low with 72 FPS, the CPU has ample headroom; the PassMark single-thread score of 3481 and Cinebench R23 single-core score of 1680 are far above what would be needed for a game running at these low frame rates. The 3DMark single-thread score of 909 and 2-thread score of 1699 further indicate that even lightly threaded workloads are handled easily. The CPU’s 12 threads and 18 MB of L3 cache provide plenty of capacity for background tasks, but the game’s performance is entirely dictated by the Arc B390’s rendering limits.

The data shows that the i5-12400F is a well-matched partner for a low-end GPU in the sense that it will never cause the frame rate to drop further. However, it also cannot compensate for the GPU’s weaknesses. The system-shared memory architecture of the Arc B390 means the CPU’s memory bandwidth is shared with the GPU, which could introduce additional latency in memory-intensive scenes. The CPU’s memory support for DDR4 and DDR5 means the effective bandwidth is system-dependent, and the GPU’s “System Dependent” bandwidth rating reflects that. In practice, the i5-12400F’s performance is sufficient to keep the GPU fed at all tested settings, but the GPU’s low fill rate and lack of dedicated VRAM cap the overall experience. For any player considering this combo, the takeaway is that the CPU is not the problem—the GPU is the ceiling, and the measured FPS data reflects that reality across every resolution and preset.
