Fortnite

The Intel Core i5-12600KF paired with the Intel Arc B390 presents a highly specific performance profile in Fortnite, characterized by a stark contrast between the CPU's strong synthetic scores and the GPU's limited measured output. The data indicates a system where the graphics processor is the primary constraint at every resolution and settings level, with the CPU demonstrating ample headroom that is never fully utilized.

Resolution Scaling

The measured FPS data shows a classic pattern of GPU-bound scaling, where performance degrades sharply as resolution increases. At 1920x1080 with Low settings, the combo achieves an average of 115 FPS. Moving to 2560x1440 at the same Low preset, the average drops to 73 FPS, a reduction of 42 FPS. At 3840x2160 Low, the average falls further to 39 FPS. This trajectory—from 115 to 73 to 39—shows that doubling the pixel count from 1080p to 4K roughly halves the frame rate, indicating that the rendering workload is overwhelming the graphics solution.

The scaling pattern is consistent across all settings presets. At High settings, the averages are 63 FPS at 1080p, 40 FPS at 1440p, and 21 FPS at 4K. The Medium preset follows the same trend, with 81 FPS at 1080p, 51 FPS at 1440p, and 27 FPS at 4K. The Ultra preset is the most demanding, producing 41 FPS at 1080p, 26 FPS at 1440p, and only 14 FPS at 4K. In every case, the step from 1080p to 1440p costs roughly 35-40% of the frame rate, and the step from 1440p to 4K costs an additional 45-50%.

This data strongly suggests that the Intel Arc B390 is the limiting component. The consistent proportional drops with increasing resolution are the signature of a GPU that is saturated. If the CPU were the bottleneck, we would expect to see frame rates remain relatively flat across resolutions, particularly at lower settings where the GPU has less work to do. Instead, the steep declines confirm that the graphics processor is working at its maximum capacity even at the lowest tested settings. The i5-12600KF, with its substantial multi-threaded capabilities, is effectively waiting on the GPU to deliver frames, never becoming the constraining factor in this configuration.

How This Combo Ranks

In the broader context of all tested combinations for Fortnite, this pairing ranks 2417 out of 2740 combos. This places the system in the lower percentile of tested hardware, specifically in the bottom 12% of all configurations. The rank is a direct reflection of the GPU's performance, as the combo's position is overwhelmingly determined by the graphics card's ability to render frames.

The CPU alone would suggest a much higher ranking. The Intel Core i5-12600KF holds a percentile of 79 against all CPUs, meaning it outperforms 79% of processors in synthetic benchmarks. Its average benchmark score of 27799 places it nearly even with rivals like the Intel Core i9-10900K (27872, delta of -0.3%) and the AMD Ryzen 7 5800X3D (27896, delta of -0.3%). This positions the CPU as a solid mid-to-high-tier performer. In contrast, the GPU's percentile is a mere 9, meaning it outperforms only 9% of all GPUs. Its benchmark score of 1482 is nearly identical to the NVIDIA GeForce GT 520MX (1463, delta of 1.3%) and the NVIDIA GeForce 800M (1460, delta of 1.5%). This massive discrepancy between the CPU's high standing and the GPU's low standing is why the combo ranks so poorly overall.

The data indicates that this is a severely imbalanced pairing for Fortnite. The system is held back entirely by its graphics solution. While the CPU offers performance comparable to a Ryzen 7 5800X3D in synthetic tests, the GPU delivers frame rates on par with entry-level discrete GPUs from over a decade ago. The resulting combo rank of 2417 is a direct consequence of this bottleneck, making the system unsuitable for competitive play at most settings.

Settings Recommendations

Based on the measured FPS rows, the most playable experience is achieved at 1920x1080 with Low settings, which produces an average of 115 FPS. This is the only configuration that breaks the 100 FPS barrier, making it the recommended choice for a smooth experience. The 1080p Medium preset, at 81 FPS average, is also viable, providing a balance between visual quality and performance, though it falls short of high-refresh-rate targets.

At 2560x1440, the situation becomes more difficult. The Low preset yields 73 FPS, which is acceptable for casual play but not ideal for fast-paced competitive scenarios. The Medium preset at 1440p drops to 51 FPS, and High falls to 40 FPS, both of which may feel sluggish in a Battle Royale setting. The Ultra preset is not recommended at any resolution, as it produces sub-60 FPS averages even at 1080p (41 FPS) and drops to 14 FPS at 4K.

For users prioritizing frame rate over visual fidelity, the clear choice is 1080p Low. For those who prefer better visuals at a moderate performance cost, 1080p Medium offers a playable experience. At 1440p, users should stick to Low settings to maintain a reasonable frame rate. The 4K resolution is effectively unplayable across all settings, with the highest average being 39 FPS at Low, which would be a poor experience for a competitive shooter. The data strongly suggests that this combo is best suited for 1080p gaming, where the GPU can produce playable frame rates with reduced graphical loads.

Measured FPS Breakdown

The complete measured FPS dataset provides a full picture of performance across three resolutions and four settings presets. At 1920x1080, the Low preset delivers an average of 115 FPS. Medium produces an average of 81 FPS, with a minimum of 69 FPS and a maximum of 93 FPS. High yields an average of 63 FPS. Ultra is the lowest at 41 FPS.

At 2560x1440, the Low preset achieves an average of 73 FPS. Medium produces an average of 51 FPS, with a minimum of 44 FPS and a maximum of 59 FPS. High yields an average of 40 FPS. Ultra drops to an average of 26 FPS.

At 3840x2160, the Low preset reaches an average of 39 FPS. Medium produces an average of 27 FPS, with a minimum of 23 FPS and a maximum of 31 FPS. High yields an average of 21 FPS. Ultra is nearly unplayable at an average of 14 FPS.

The frame time consistency, as indicated by the min/max values for the Medium preset, shows relatively tight ranges. At 1080p Medium, the spread between minimum and maximum is 24 FPS (69 to 93). At 1440p Medium, the spread is 15 FPS (44 to 59). At 4K Medium, the spread is 8 FPS (23 to 31). This suggests that while the average frame rates are low, the frame pacing is stable, with no severe stuttering or spikes observed in the measured data. The system appears to deliver consistent, if low, performance rather than erratic frame times.

GPU Role

The Intel Arc B390 is a GPU with specifications that clearly explain its measured performance. Its architecture is Xe3-LPG on a 3 nm process node, with a boost clock of 2500 MHz. It features 1536 shading units, 48 texture mapping units, and 24 raster operation units. The memory configuration is "System Shared," meaning it relies on the host system's RAM rather than dedicated VRAM. This is a critical factor, as memory bandwidth is listed as "System Dependent," which can severely limit performance in a game like Fortnite.

The GPU's 3DMark Steel Nomad DX12 score is 1482, placing it at the 9th percentile of all GPUs. Its nearest rivals in synthetic testing are the NVIDIA GeForce GT 520MX (1463, delta 1.3%) and the NVIDIA GeForce 800M (1460, delta 1.5%). These are extremely old, low-end mobile GPUs, which puts the Arc B390's performance in perspective. The measured FPS data aligns with this low synthetic score, confirming that the GPU is not capable of handling modern game loads at high resolutions.

The lack of dedicated VRAM and reliance on shared system memory is a major contributor to the poor results. The texture rates and pixel rates, while specified at 120.0 GTexel/s and 60.00 GPixel/s respectively, do not translate into playable frame rates due to the memory bottleneck. The GPU's TDP is 80 W, and it is an IGP (Integrated Graphics Processor) with a slot width of "IGP," indicating it is likely a mobile or integrated solution rather than a discrete card. This explains its poor standing relative to even basic discrete GPUs. The data shows that this GPU is fundamentally mismatched for a demanding title like Fortnite at 1080p or higher, with the shared memory architecture being a primary handicap.

CPU Role

The Intel Core i5-12600KF is a 10-core, 16-thread processor based on the Alder Lake architecture. It has a base clock of 3.70 GHz and a boost clock of 4.90 GHz. The CPU's cache configuration includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. This hardware, combined with a TDP of 125 W, makes it a capable processor for gaming and productivity tasks.

Its synthetic benchmark scores are strong. In Cinebench R23, it scores 23391 in multi-core and 3302 in single-core. In 3DMark, it scores 7956 in the 16-thread test and 1016 in the single-thread test. The CPU's average benchmark score is 27799, placing it at the 79th percentile of all CPUs. This places it in direct competition with the Intel Core i9-10900K (27872, delta -0.3%) and the AMD Ryzen 7 5800X3D (27896, delta -0.3%).

In this Fortnite configuration, however, the CPU's performance headroom is entirely untapped. The measured FPS at all resolutions and settings is dictated by the GPU's limitations. For example, at 1080p Low, the system produces 115 FPS, but the CPU is capable of far more in synthetic tests. The GPU's 9th percentile standing and shared memory architecture create a bottleneck that prevents the CPU from ever being the limiting factor. The CPU's high single-thread score of 3302 in Cinebench R23 would be beneficial for a game like Fortnite, which relies heavily on single-core performance, but the GPU cannot deliver frames fast enough to utilize this strength. The data clearly shows that the CPU is not the constraint; rather, it is the graphics solution that holds this combo back.
