Assetto Corsa

Assetto Corsa, a racing simulation from 2014, remains a demanding title at higher settings. The measured data for the Intel Core i5-9400 paired with the Intel Arc B570 reveals a system that is capable of delivering high frame rates at mainstream resolutions, but one that faces significant challenges at 4K with maximum graphical presets. This analysis breaks down the performance metrics from the benchmark database, focusing on the roles of the CPU and GPU, scaling across resolutions, and optimal settings for the best experience.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-9400 is a 6-core, 6-thread processor from the Coffee Lake architecture, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. It has a 9 MB shared L3 cache and supports dual-channel DDR4 memory. In the broader context of all CPUs, it sits at the 47th percentile, with an average benchmark score of 2254. Its nearest rivals in synthetic tests include the Intel Core i7-1068NG7 (0.2% slower) and the AMD Ryzen 5 PRO 1500 (0.4% faster), indicating that its raw compute power is solidly mid-range.

For a racing simulation like Assetto Corsa, the CPU is responsible for game logic, physics calculations, and AI opponent behavior, which are typically single-threaded or lightly threaded tasks. The i5-9400’s single-core performance, as indicated by a Cinebench R23 single-core score of 935, is adequate for this title. The data suggests that the CPU is not the primary bottleneck at most settings. At 1080p with High settings, the system produces 96 FPS, and at Low settings, it jumps to 181 FPS. This significant jump when lowering settings that primarily affect the GPU suggests that the CPU is capable of feeding frames far beyond what the GPU can render at higher quality presets.

The 6-thread configuration is sufficient for a game from this era. While modern titles might utilize more threads, Assetto Corsa's engine scales well with fewer, faster cores. The fact that the CPU's average benchmark score is nearly identical to its rivals (all within 0.4%) reinforces that this is a predictable, mid-tier performer. The data shows that the i5-9400 provides a stable foundation, allowing the GPU to be the deciding factor in frame rate at higher resolutions and settings. The processor’s 65 W TDP and 14 nm process node are part of its profile, but the measured FPS indicates that its performance headroom is not exhausted in this specific pairing.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B570 is a discrete graphics card based on the Xe2-HPG architecture (Battlemage generation), built on a 5 nm process. It features 10 GB of GDDR6 memory on a 160-bit bus, providing a bandwidth of 380.0 GB/s. The GPU is equipped with 2304 shading units, 144 texture mapping units, and 80 raster output units. Its boost clock is a static 2500 MHz. The B570 sits at the 65th percentile of all GPUs, with an average benchmark score of 20556. Its nearest rivals in synthetic benchmarks are the NVIDIA GeForce RTX 3070 Mobile (0.1% faster) and the Intel Arc A750 (0.1% slower), placing it in a competitive performance tier.

In Assetto Corsa, the GPU is the primary driver of visual fidelity, handling shadows, textures, and post-processing effects. The 10 GB VRAM buffer is more than sufficient for this 2014 title, even at 4K, where it avoids any memory-related stuttering or texture pop-in. The GPU's raw throughput is the limiting factor as resolution and settings increase. For instance, at 1440p, the average FPS drops from 127 on Low to 55 on Ultra, a clear indication of the GPU's workload scaling with graphical complexity.

The comparison to the Intel Arc A750 is notable; the B570 performs nearly identically in synthetic benchmarks. However, in actual game data, the B570 shows strong scaling. The measured FPS at 1080p Medium (127 FPS) is particularly high, suggesting good driver optimization for this specific title. The GPU's 150 W TDP and dual-slot design are physical characteristics, but the performance data shows it is a capable mid-range card, though it struggles to maintain playable frame rates at 4K Ultra, where it only manages 33 FPS. This positions the B570 as a card best suited for 1080p and 1440p gaming in this simulation.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions provides a clear picture of system scaling. At 1080p, the system is capable of very high frame rates, indicating a balanced configuration where the GPU is the primary bottleneck but has enough headroom. Moving from 1080p to 1440p, there is a predictable performance drop, and moving to 4K shows a dramatic reduction, confirming that the Arc B570 is the limiting component at higher resolutions.

For High settings, the average FPS drops from 96 at 1080p to 67 at 1440p (a 30% decrease) and then to 41 at 4K (a 39% decrease from 1440p). This pattern is consistent with a GPU-bound scenario. The scaling is not linear, with the jump to 4K being particularly punishing due to the quadruple pixel count relative to 1080p. At Low settings, the frame rates are exceptionally high: 181 FPS at 1080p, 127 FPS at 1440p, and 76 FPS at 4K. The drop from 1080p to 1440p is 30%, and from 1440p to 4K is 40%, showing that even at low graphical fidelity, the GPU is still the main constraint.

The most telling data point is the comparison between Low and Ultra at 4K. The system achieves 76 FPS on Low but only 33 FPS on Ultra. This 43 FPS difference (a 57% reduction) highlights the GPU's sensitivity to visual effects. The CPU is not the bottleneck here; if it were, the frame rates would remain more constant regardless of resolution. The fact that FPS scales inversely with resolution and settings confirms that the Intel Arc B570's rendering throughput is the definitive limiting factor in this pairing. The 1080p Medium result of 127 FPS also suggests that the i5-9400 can easily keep up, as this is a higher frame rate than the 4K Low result, which places more stress on the GPU.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. The data provides clear guidance for each resolution tier.

At 1920x1080, the system is overperforming for most presets. The High preset yields an average of 96 FPS, which is smooth and visually appealing. The Medium preset offers 127 FPS, which is excellent for high-refresh-rate monitors. The Ultra preset still delivers a playable 78 FPS. The data suggests that High is the sweet spot for a balance of visual quality and performance, but Ultra is entirely viable if maximum fidelity is preferred. The Low preset (181 FPS) is only necessary for competitive play at extreme refresh rates.

At 2560x1440, the Medium preset provides an average of 89 FPS (with a minimum of 76 FPS), which is a solid experience for most users. The High preset drops to 67 FPS, which is still playable but begins to show the GPU's limits. The Ultra preset at 55 FPS is playable but may feel less smooth in fast-paced sections. For 1440p, the Medium preset is recommended as it maintains a high average frame rate while providing a substantial visual upgrade over Low. The 76 FPS minimum ensures that there are no significant stutters.

At 3840x2160 (4K), the data shows that this combo is not suited for high or ultra settings. The Ultra preset yields only 33 FPS, which is below the threshold for a smooth experience. The High preset (41 FPS) is marginally better but still compromised. The Medium preset (54 FPS, with a minimum of 46 FPS) is the only playable option at 4K, offering a decent frame rate for a driving sim. The Low preset (76 FPS) is very playable but sacrifices most graphical enhancements. Consequently, for 4K, the Medium preset is the recommended choice, as it provides the best balance between the playable frame rate and visual quality. For any resolution above 1080p, users should avoid the Ultra preset if they prioritize a consistent frame rate.
