Assetto Corsa

Assetto Corsa, the 2014 racing simulation, remains a staple in benchmark databases due to its longevity and active modding community. For this analysis, the Intel Core i5-14600K is paired with the Intel Arc B580, a combination that yields a specific performance profile across resolutions and settings. The measured data provides a clear picture of how this hardware handles the game’s engine, with results indicating a strong balance between CPU and GPU capabilities at various graphical loads.

The data set covers four presets (Low, Medium, High, Ultra) across three resolutions (1920x1080, 2560x1440, 3840x2160), offering a comprehensive view of scaling behavior. This analysis will break down the performance metrics, interpret the limiting factors, and provide actionable recommendations based solely on the measured frames per second (FPS) data.

Resolution Scaling

The transition from 1080p to 4K reveals a predictable but significant shift in system bottleneck. At 1920x1080, the average frame rates are exceptionally high across all settings, ranging from 88.5 FPS on Ultra to 205.3 FPS on Low. These figures suggest that at this resolution, the Intel Core i5-14600K is providing ample headroom, allowing the Intel Arc B580 to operate near its full potential. The game is not heavily taxing the CPU at this level, as evidenced by the high minimum frame rates and the relatively small performance gap between the Low and Ultra presets.

Moving to 2560x1440, the frame rates drop considerably, but remain highly playable. The High preset delivers 75.3 FPS, while the Low preset still achieves 140.6 FPS. This indicates a growing reliance on the GPU, as the pixel count increases. The gap between Low and Ultra widens, with the Ultra preset falling to 60.6 FPS, a 57% reduction from the Low preset’s performance. This scaling suggests that the Arc B580 is beginning to become the primary limiting factor, though the CPU still maintains a solid baseline.

At 3840x2160, the GPU bottleneck becomes fully apparent. The Ultra preset drops to 38.4 FPS, making it marginally playable for a simulation where consistent frame pacing is critical. The High preset manages 46.9 FPS, while the Medium and Low presets return 61.0 and 83.5 FPS, respectively. The scaling from High to Ultra is a steep 18% performance loss, indicating that the Arc B580’s memory bandwidth and compute resources are saturated at this resolution. The data shows that 4K gaming with this combo is best reserved for lower presets, as the GPU’s 12 GB memory and 456.0 GB/s bandwidth are challenged by the higher resolution’s demands.

A: The average frame rate falls from 109.8 FPS at 1920x1080 to 46.9 FPS at 3840x2160. This represents a 57% reduction in performance, highlighting the heavy load placed on the GPU at 4K.

Q: Does the Ultra preset ever reach 60 FPS?

A: Yes, but only at 1920x1080, where it achieves 88.5 FPS. At 2560x1440, it drops to 60.6 FPS, just barely exceeding the 60 FPS mark. At 3840x2160, it falls to 38.4 FPS.

Settings Recommendations

Based on the measured data, the optimal experience depends on the user’s display and preference for frame rate over visual fidelity. For users with 1080p displays, the Ultra preset is the clear choice, as the 88.5 FPS average provides a fluid experience without sacrificing visual detail. The High preset is also viable, offering a 24% higher frame rate (109.8 FPS) for those who prioritize higher refresh rates.

For 1440p displays, the High preset is the recommended starting point, delivering 75.3 FPS. This strikes an excellent balance between image quality and smoothness. Users with high refresh rate monitors (144Hz+) may prefer the Medium preset, which achieves 101.9 FPS, though this comes with a noticeable reduction in graphical fidelity. The Ultra preset at 60.6 FPS is playable but sits close to the edge of what is ideal for a racing sim where consistent frame times are important.

At 4K, the recommendations shift dramatically. The Medium preset, at 61.0 FPS, is the highest setting that consistently maintains a stable frame rate above 60 FPS. The Low preset offers a much higher 83.5 FPS, which is beneficial for users who prioritize performance above all else. The High and Ultra presets are not recommended for 4K, as the sub-50 FPS averages (46.9 and 38.4 FPS, respectively) will likely result in noticeable stutter and less responsive input.

How This Combo Ranks

The Intel Core i5-14600K and Intel Arc B580 combination ranks 1344 out of 1721 tested combos in Assetto Corsa. This places it in the lower 22% of all configurations, which may seem surprising given the high frame rates observed at 1080p and 1440p. This ranking is likely influenced by the database’s inclusion of many high-end systems with more powerful GPUs, which can achieve much higher frame rates at 4K Ultra settings.

The CPU itself is a strong performer, with a percentile rank of 93 against all CPUs and an average benchmark score of 49166. It is closely matched with the AMD Ryzen 9 5950X (0.2% faster) and the Intel Core i5-14600KF (0.4% slower). The GPU, however, has a lower percentile rank of 66 against all GPUs, with an average score of 23021. It performs similarly to the NVIDIA GeForce RTX 4060, which is only 0.7% faster in synthetic benchmarks.

The combo’s rank of 1344 suggests that while the CPU is capable, the Arc B580 holds back overall performance in this specific title, particularly at higher resolutions. For users seeking a higher rank, upgrading the GPU would be the primary lever, as the CPU has significant headroom based on its benchmark scores.

CPU Role

The Intel Core i5-14600K is a 14-core processor (6 Performance-cores and 8 Efficient-cores) with 20 threads. Its base clock is 3.50 GHz, and it can boost up to 5.30 GHz. This architecture, combined with 24 MB of shared L3 cache, provides strong single-threaded performance, which is critical for a racing simulator like Assetto Corsa that relies heavily on physics and AI calculations.

The CPU’s benchmark results support its capability. It scores 32881 in Cinebench R23 multi-core and 4642 in single-core tests. In Geekbench, it achieves 15846 multi-core and 2803 single-core. This level of performance ensures that at lower resolutions, the CPU is not the bottleneck. The data confirms this, as the frame rates at 1080p scale well with GPU settings, indicating the CPU can feed frames quickly.

However, the CPU’s role diminishes at higher resolutions, where the GPU’s workload increases. The frame rate drops from 205.3 FPS at 1080p Low to 83.5 FPS at 4K Low, a 59% reduction that is almost entirely attributable to the GPU’s pixel processing limits. The CPU’s high boost clock of 5.30 GHz and robust core count ensure it remains responsive, but the Arc B580’s 13.67 TFLOPS of FP32 compute becomes the deciding factor in this game’s performance at 4K.
