Fortnite

The Intel Core i5-12400F paired with the Intel Arc B580 occupies the 1194th position out of 1564 tested combinations in Fortnite, placing it in the lower-middle tier of the database. This rank of 1194 out of 1564 means the combo sits in the 24th percentile of all tested pairings, a position that reflects a hardware pairing capable of playable frame rates but not one that dominates the leaderboard. The data shows a significant spread in performance depending on settings and resolution, with the combo’s best result reaching 200.1 FPS at 1080p Low, while its worst measured output drops to 26.1 FPS at 4K Ultra. This wide range indicates that the pairing’s ranking is heavily influenced by the workload, as the system can shift from a high-refresh-rate machine to a barely playable one based purely on graphical demands.

How This Combo Ranks

The 1194th rank out of 1564 combos places this configuration firmly in the lower half of tested systems, yet the measured FPS data suggests this overall position masks a more nuanced story. At 1080p Low, the combo achieves 200.1 FPS, which would likely place it much higher in a ranking focused solely on competitive settings. Conversely, at 4K Ultra with 26.1 FPS, the same hardware falls to a position that would rank near the bottom of any list. The average benchmark scores for the individual components help contextualize this: the CPU’s average score of 19221 puts it in the 77th percentile of all processors, while the GPU’s average score of 23021 places it in the 66th percentile of all graphics cards. When combined, these mid-tier components produce a system that is neither a top performer nor a weak one, but rather one that sits in a crowded middle ground where settings choices matter more than raw hardware potential. The rank of 1194 out of 1564 translates to roughly 76% of tested combos performing better overall, which aligns with the component percentiles showing both parts below the 80th percentile mark.

GPU Role

The Intel Arc B580 brings 12 GB of GDDR6 memory on a 192-bit bus, delivering a bandwidth of 456.0 GB/s, which is substantial for a card in this class. Its memory clock runs at 2375 MHz, translating to 19 Gbps effective, while the base and boost clocks are both set to 2670 MHz. The GPU’s compute capabilities include 2560 shading units, 160 TMUs, and 80 ROPs, with 20 ray tracing cores, producing a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s. The FP32 throughput is 13.67 TFLOPS, and the card supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. In Fortnite, the GPU’s role becomes clear when examining the resolution scaling: at 1080p Low, the system hits 200.1 FPS, but at 4K Low, it drops to 67.9 FPS. This 66% reduction in frame rate from 1080p to 4K at the same settings indicates the GPU is the primary bottleneck at higher resolutions, as the 12 GB VRAM and 456.0 GB/s bandwidth are being saturated by the increased pixel workload. The GPU’s percentile rank of 66 and its nearest rival, the NVIDIA GeForce RTX 4060, which it trails by only 0.7%, suggest that the B580 is a capable mid-range card, but Fortnite’s demanding effects at Ultra settings push it to its limits, as evidenced by the 26.1 FPS result at 4K Ultra.

CPU Role

The Intel Core i5-12400F provides 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This Alder Lake-S architecture chip has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache, operating on a 10 nm process. Its benchmark scores show a single-thread performance of 2332 in Cinebench R23 and a multi-core score of 16518 in the same test, with the CPU achieving a 77th percentile ranking overall. In Fortnite, the CPU’s influence is most apparent at lower resolutions where the GPU is less stressed. At 1080p Low, the combo reaches 200.1 FPS, and at 1080p Medium, it achieves 141.6 FPS, suggesting the CPU can feed the GPU adequately at these settings. However, the CPU’s 6-core, 12-thread configuration may limit performance in Fortnite’s more demanding scenes, as the game’s battle royale mode often requires handling many players and build structures simultaneously. The CPU’s nearest rival, the Intel Core i7-8700K, scores nearly identically at 19210 versus the i5-12400F’s 19221, a delta of only 0.1%, indicating that the i5-12400F punches above its class in synthetic benchmarks. In actual gameplay, the 4.40 GHz boost clock helps maintain high frame rates in CPU-bound scenarios, but the data shows that at 1080p, the GPU still has headroom, as moving from Low to Medium settings only drops FPS from 200.1 to 141.6, a 29% reduction, which is less than the proportional increase in GPU load.

FAQ

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, with the severity varying by settings preset. At Low settings, the combo delivers 200.1 FPS at 1080p, 123.9 FPS at 1440p, and 67.9 FPS at 4K. This represents a 38% drop from 1080p to 1440p and a further 45% drop from 1440p to 4K, totaling a 66% reduction from the starting point. At High settings, the progression is 110.7 FPS at 1080p, 66.7 FPS at 1440p, and 35 FPS at 4K, showing a 40% drop from 1080p to 1440p and a 48% drop from 1440p to 4K. The Medium preset follows a similar trajectory: 141.6 FPS at 1080p, 88.4 FPS at 1440p, and 49.4 FPS at 4K. Ultra settings exhibit the most dramatic scaling, with 70.2 FPS at 1080p falling to 46.5 FPS at 1440p and then to 26.1 FPS at 4K. The consistency of these drops across all presets indicates the GPU is the primary scaling bottleneck, as the CPU’s workload does not increase proportionally with resolution. The fact that the relative drop from 1080p to 4K is remarkably similar across presets — around 66-68% for Low, Medium, and High — points to a GPU that is uniformly constrained by pixel throughput, with the 456.0 GB/s bandwidth and 13.67 TFLOPS compute being the limiting factors rather than any specific setting.

Settings Recommendations

The data provides a clear hierarchy for optimal settings based on the measured FPS values. For competitive play where frame rate is paramount, the Low preset at 1080p delivers 200.1 FPS, which is 41% higher than the next best option of 141.6 FPS at 1080p Medium. This makes Low the clear choice for esports-focused players. For a balance of visual quality and performance, the Medium preset at 1080p offers 141.6 FPS, which remains above the 120 FPS threshold commonly desired for smooth gameplay. At 1440p, the Low preset achieves 123.9 FPS, making it viable for high-refresh-rate monitors, while Medium at 1440p drops to 88.4 FPS, which is still playable but not ideal for fast-paced action. The High preset at 1080p produces 110.7 FPS, which is acceptable but offers only marginal visual improvements over Medium at a 22% performance cost. The Ultra preset should generally be avoided, as even at 1080p it only reaches 70.2 FPS, and at 4K it becomes unplayable at 26.1 FPS. The best experience per the measured rows is achieved by using Low settings at 1080p or 1440p, as these configurations provide the highest frame rates with the least compromise, while Medium at 1080p serves as the best option for players who prioritize visuals without sacrificing responsiveness. The data shows no scenario where High or Ultra settings are recommended given the substantial FPS penalties they incur across all resolutions.
