Fortnite

The AMD Ryzen 5 7500F paired with the Intel Arc B370 produces a highly constrained gaming experience in Fortnite, with benchmark results clearly demonstrating that the graphics processor is the primary bottleneck across all tested settings. The data indicates a system where the CPU’s substantial processing power is largely left untapped, as frame rates are consistently dictated by the GPU’s limited throughput. This analysis walks through the measured FPS data to explain how resolution scaling, GPU architecture, and settings choices interact, and where this specific component combination ranks among the 2,740 tested combos.

Resolution Scaling

The measured FPS data shows a severe drop in performance as resolution increases, which is the classic signature of a GPU-bound scenario. At 1920x1080 with Low settings, the combo achieves an average of 104 FPS. Moving to 2560x1440 at the same Low preset drops the average to 66 FPS, a reduction of 38 FPS. At 3840x2160, the average falls further to 35 FPS. This linear degradation pattern — roughly halving the frame rate when pixel count quadruples from 1080p to 4K — indicates that the Intel Arc B370 is working at its maximum capacity even at the lowest settings.

The scaling behavior becomes even more pronounced at higher quality presets. With High settings, the average FPS drops from 57 at 1920x1080 to 36 at 2560x1440, and finally to 19 at 3840x2160. The Ultra preset shows the most dramatic collapse: 37 FPS at 1080p, 24 FPS at 1440p, and just 13 FPS at 4K. This pattern reveals that the GPU’s pixel throughput and shading resources are exhausted early, and adding resolution stress disproportionately impacts performance. The data suggests that the limiting component is unequivocally the GPU, as the CPU’s 6 cores and 12 threads are more than capable of feeding frames at these rates.

Comparing the 1080p to 4K scaling factor across presets provides further insight. At Low settings, the 4K average (35 FPS) is exactly one-third of the 1080p average (104 FPS). At Medium settings, the 4K average (25 FPS) is roughly 34% of the 1080p average (73 FPS). At High settings, the 4K average (19 FPS) is about 33% of the 1080p figure (57 FPS). This consistent ~33% retention at 4K across all presets confirms that the GPU is the bottleneck; a CPU-limited system would show a much flatter scaling curve, with frame rates remaining similar as resolution increases. The data indicates that Fortnite’s rendering workload at higher resolutions overwhelms the Arc B370’s capabilities, leaving no headroom for the Ryzen 5 7500F to demonstrate its potential.

GPU Role

The Intel Arc B370 is the decisive factor in this combo’s performance, and its specifications explain why the measured FPS numbers are so low. The GPU features a base clock of 300 MHz and a boost clock of 2400 MHz, with 1280 shading units, 40 texture mapping units, and 20 raster output units. Its FP32 performance is rated at 6.144 TFLOPS, and it supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Critically, the memory configuration is "System Shared" with "System Dependent" bandwidth, meaning the GPU relies on the CPU’s DDR5 memory rather than dedicated VRAM. This shared memory setup is a fundamental limitation, as the memory bus width is also listed as "System Shared," creating a potential bandwidth bottleneck that directly impacts high-resolution performance.

The GPU’s benchmark results corroborate the FPS data. In the 3DMark Steel Nomad DX12 test, the Arc B370 scores 1184, placing it in the 5th percentile of all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570 (score 1186, deltaPct -0.2), ATI Radeon HD 5770 (score 1190, deltaPct -0.5), and AMD Radeon HD 7650M (score 1192, deltaPct -0.7). These are all older, lower-end parts, and the Arc B370’s performance relative to them is essentially flat, with deltas ranging from -0.7% to +1.4% against the AMD FirePro M2000 (score 1168). This context shows that the GPU is operating at a level comparable to hardware from a much earlier generation, which explains why Fortnite’s modern rendering demands result in sub-60 FPS averages at most settings.

The GPU’s 25 W TDP and IGP (integrated graphics processor) form factor further reinforce its limited role. With a slot width of "IGP" and no power connectors, the Arc B370 is designed for low-power, portable applications, not high-performance desktop gaming. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are modest figures, and when combined with the shared memory architecture, they produce the measured frame rates. The data shows that the GPU’s role in this combo is to act as a strict ceiling — no matter how capable the CPU is, the Arc B370 cannot push beyond roughly 104 FPS even at the lowest settings and resolution.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend heavily on the target resolution and the user’s tolerance for frame rate fluctuations. At 1920x1080, the Low preset delivers an average of 104 FPS, which is the only configuration that approaches high-refresh-rate territory. The Medium preset at 1080p yields 73 FPS average with a minimum of 62 FPS and maximum of 84 FPS, offering a playable experience with improved visuals. High at 1080p drops to 57 FPS average, which is still technically playable but notably less smooth. Ultra at 1080p falls to 37 FPS, which is below the threshold for competitive play.

At 2560x1440, the data shows that only the Low preset (66 FPS average) remains comfortably playable. Medium at 1440p produces 46 FPS average with a minimum of 39 FPS, which may be acceptable for single-player experiences but is marginal for fast-paced battle royale action. High at 1440p (36 FPS) and Ultra at 1440p (24 FPS) are not recommended for any serious gaming, as frame rates dip into ranges where input latency becomes noticeable.

At 3840x2160, none of the presets achieve a playable frame rate. Low delivers 35 FPS average, Medium 25 FPS (with a minimum of 21 FPS), High 19 FPS, and Ultra 13 FPS. The data suggests that 4K is simply not viable with this combo, regardless of settings. The best experience per the measured rows is clearly the 1080p Low preset, which maximizes frame rate at 104 FPS average. If visual fidelity is a priority, the 1080p Medium preset (73 FPS average) offers a reasonable compromise, but the 1080p High preset (57 FPS) represents the upper limit of playable quality settings. For competitive play, users should stick to 1080p Low, as the jump to 1440p Low (66 FPS) introduces a significant frame rate penalty without proportional visual gains.

FAQ

CPU Role

The AMD Ryzen 5 7500F is a capable processor whose potential is largely wasted in this configuration. With 6 cores and 12 threads, a base clock of 3.70 GHz, and a boost clock of 5.00 GHz, the CPU is built on TSMC’s 5 nm process with a 65 W TDP. Its cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. The CPU supports DDR5 memory with dual-channel configuration, offering a memory bandwidth of 83.2 GB/s. Benchmark results show strong synthetic performance: Cinebench R23 multicore scores 22799 and single-core scores 3218, while Geekbench multicore reaches 12362 and single-core 2374. The CPU’s average benchmark score is 24964, placing it in the 77th percentile of all CPUs.

The CPU’s nearest rivals in benchmark performance include the Intel Core i7-11850H (avg score 24935, deltaPct 0.1), AMD Ryzen 5 8400F (25005, -0.2), Intel Core i7-13620H (24911, 0.2), and Intel Core 5 210H (24872, 0.4). These deltas are all under 0.5%, indicating that the Ryzen 5 7500F performs essentially on par with these alternatives. In Fortnite, however, this CPU power does not translate to high frame rates because the GPU cannot deliver enough frames. The measured FPS data shows that even at 1080p Low (104 FPS), the CPU is likely not the limiting factor, as the GPU’s shared memory and low shading unit count create a hard ceiling. The CPU’s role is to feed the GPU with draw calls and game logic, but with a GPU that scores in the 5th percentile, the CPU is never stressed to its limits.

The data suggests that the Ryzen 5 7500F would perform significantly better in Fortnite if paired with a more powerful GPU. Its 12 threads and high boost clock are well-suited for modern games, but the current combo means the CPU idles while the GPU struggles. The CPU’s 3DMark scores — 6376 for 16 threads, 6379 for max threads, and 974 for single thread — further confirm its capability, but these numbers are irrelevant to the final FPS output in this specific pairing. The bottleneck is clear, and the CPU is not the component to upgrade if seeking better Fortnite performance in this system.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combo’s performance across three resolutions and four settings presets. At 1920x1080, the Low preset achieves the highest average at 104 FPS, followed by Medium at 73 FPS (min 62, max 84), High at 57 FPS, and Ultra at 37 FPS. The 1080p results show a clear progression: each step up in settings costs roughly 20-25 FPS on average. The Medium preset’s minimum of 62 FPS is notable, as it shows the system can maintain playable frame rates even during demanding scenes at this resolution.

At 2560x1440, the Low preset delivers 66 FPS average, which is a 38 FPS drop from the 1080p Low figure. Medium at 1440p produces 46 FPS average (min 39, max 53), High drops to 36 FPS, and Ultra falls to 24 FPS. The 1440p data shows that the Medium preset’s minimum of 39 FPS is near the edge of playability, while the Ultra preset at 24 FPS is clearly unplayable for a competitive shooter. The scaling from 1080p to 1440p is not linear — the 1440p Low average (66 FPS) is 63% of the 1080p Low average (104 FPS), while the 1440p Ultra average (24 FPS) is 65% of the 1080p Ultra average (37 FPS).

At 3840x2160, all presets produce average FPS below 40. Low achieves 35 FPS, Medium 25 FPS (min 21, max 28), High 19 FPS, and Ultra 13 FPS. The 4K data shows the GPU is completely overwhelmed, with even the lowest settings failing to reach 36 FPS average. The Medium preset’s minimum of 21 FPS highlights the instability at this resolution. The measured rows reveal a system that is only suitable for 1080p gaming, with 1440p viable only at Low settings, and 4K entirely impractical.

How This Combo Ranks

The combo of AMD Ryzen 5 7500F and Intel Arc B370 ranks 2517 out of 2740 tested combinations in Fortnite, placing it in the bottom 8% of all combos. This low ranking is a direct consequence of the GPU’s weak performance, as the CPU alone would rank much higher based on its 77th percentile benchmark standing. The GPU’s 5th percentile rank in its own benchmark category drags the entire combo down, resulting in a position that reflects the worst-case scenario for this pairing.

The rank of 2517 means that 223 combos perform worse than this setup, while 2516 combos perform better. The data suggests that the GPU is the primary driver of this ranking, as the CPU’s strong synthetic scores (Cinebench R23 multicore 22799, Geekbench multicore 12362) cannot compensate for the GPU’s inability to render frames. In practical terms, this ranking indicates that most other tested CPU-GPU combinations in Fortnite would deliver higher average FPS at the same settings and resolutions. The combo’s performance is consistent with the GPU’s nearest rivals — all of which are older or lower-end parts — confirming that the Arc B370 is the limiting factor. For users considering this combo, the ranking data shows that it is not competitive for Fortnite, and the measured FPS figures at higher resolutions make it unsuitable for modern gaming standards.
