Assetto Corsa

Assetto Corsa remains a demanding title for low-power hardware, and the combination of the AMD Ryzen 5 8400F and Intel Arc B370 produces a specific performance profile that is heavily dictated by resolution and settings. The measured data shows a system that can deliver playable frame rates at 1080p with the right settings, but which struggles significantly as resolution increases, clearly identifying the integrated-class GPU as the primary bottleneck in this pairing.

Resolution Scaling

The frame rate data reveals a steep and predictable decline as resolution scales up from 1080p to 4K. At 1080p with Low settings, the combo achieves an average of 106 FPS, which drops to 74 FPS at 1440p and further to 45 FPS at 4K. This represents a 30% decrease when moving from 1080p to 1440p, and a 39% decrease from 1440p to 4K. The trend is consistent across all settings presets, though the absolute numbers vary.

This scaling pattern is a textbook indicator of a GPU-bound scenario. The Arc B370's performance is being saturated by the increasing pixel count, and the CPU is not the limiting factor here. For instance, at 1080p Medium, the system averages 75 FPS, but at 1440p Medium it falls to 52 FPS — a 31% drop. At 4K Medium, it plummets to 32 FPS. The fact that the frame rate nearly halves from 1080p to 4K at the Medium preset (75 to 32 FPS) confirms that the graphics processor is doing the heavy lifting and is overwhelmed at higher resolutions.

The data shows that 4K is simply not a viable target for this combo in Assetto Corsa. Even at the lowest settings, the average FPS at 3840x2160 is 45, which is below the 60 FPS threshold most drivers consider smooth. At High settings, 4K yields only 24 FPS, and Ultra drops to 19 FPS, making the game essentially unplayable at that resolution. The GPU's pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are simply insufficient for the 8.3 million pixels at 4K, especially with higher-detail textures and effects.

The transition from 1080p to 1440p is more nuanced. While 1440p Low at 74 FPS is playable, 1440p High at 39 FPS is not smooth. This suggests that 1440p is only feasible with significant graphical compromises. The sweet spot for this hardware is clearly 1080p, where even the High preset (56 FPS) is borderline playable, and the Low preset provides a comfortable margin above 60 FPS. The measured data indicates that the limiting component at all resolutions above 1080p is unequivocally the GPU, as the CPU's performance headroom is not being utilized.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Xe3-LPG architecture and built on Intel's 3 nm process. Its performance in this game is extremely limited, as evidenced by its 5th percentile ranking among all GPUs and an average benchmark score of just 1184 in 3DMark Steel Nomad. The measured FPS data in Assetto Corsa aligns with this low standing, showing that the GPU struggles to maintain high frame rates even at modest resolutions.

The GPU's specifications explain its behavior. It operates with a base clock of 300 MHz and a boost clock of 2400 MHz. While the boost clock is respectable, the chip has only 1280 shading units, 40 TMUs, and 20 ROPs. This limited hardware configuration results in a FP32 performance of 6.144 TFLOPS, which is modest by modern standards. The memory situation is particularly problematic: the Arc B370 uses "System Shared" memory, meaning its bandwidth is "System Dependent." This means the GPU is reliant on the system's DDR5 RAM, which, while fast, is not dedicated to graphics and introduces latency and bandwidth sharing with the CPU.

The nearest rivals for this GPU are all legacy parts, which is telling. It performs within 1% of the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, and AMD Radeon HD 7650M. The delta percentages are minimal: -0.2% against the HD 5570 and -0.5% against the HD 5770. This places the Arc B370's raw graphics compute power in the same tier as graphics cards from over a decade ago. In a racing simulation like Assetto Corsa, which has moderate visual demands but requires consistent frame pacing, this level of performance is insufficient for high-resolution or high-detail gaming.

The GPU's 25 W TDP and "IGP" slot width confirm its integrated nature, and the lack of dedicated VRAM means that texture-heavy scenes at 4K will cause stuttering and frame drops as the system struggles to feed the GPU with data. The measured minimum FPS at 4K Medium is 27, with a maximum of 36, showing significant frame time variance. This instability is a direct consequence of the shared memory architecture, which cannot provide consistent bandwidth for high-resolution rendering. For this game, the Arc B370 is the definitive performance ceiling, and any attempt to raise resolution or settings will be met with immediate and severe FPS penalties.

How This Combo Ranks

In the aggregate database of tested hardware combinations, this pairing of the Ryzen 5 8400F and Intel Arc B370 ranks 3427 out of 3712 combos for Assetto Corsa. This places it in the bottom 8% of all tested systems, which is a poor showing for a modern CPU release. The rank reflects the GPU's severe limitations, not the CPU's capabilities.

The combo rank is a holistic metric that accounts for the performance at all measured resolutions and settings. Given the GPU's 5th percentile ranking, the overall system ranking is dragged down significantly. While the CPU is a capable part — ranking in the 77th percentile among all CPUs — it cannot compensate for the GPU's inability to render frames quickly. The data shows that this is a severely imbalanced pairing for gaming, where the GPU is the clear performance bottleneck.

Comparatively, the CPU's nearest rivals are the AMD Ryzen 5 7500F (0.2% faster), Intel Core i7-11850H (0.3% slower), and Intel Core i7-13620H (0.4% slower). These are all desktop or high-end mobile processors with similar average benchmark scores around 25,000. The Ryzen 5 8400F's average benchmark score of 25005 is nearly identical to these parts, confirming that the CPU is not the source of the low combo ranking. The bottleneck is exclusively the Arc B370, which is the lowest-performing component in this build. The 3427th rank out of 3712 combos is a direct consequence of pairing a mid-range CPU with an entry-level integrated GPU, and the measured FPS data confirms that the system behaves exactly as this rank suggests.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Phoenix, and manufactured on TSMC's 4 nm process. It has a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The CPU's cache configuration includes 64 KB of L1 per core, 1 MB of L2 per core, and a shared 16 MB of L3 cache. It supports DDR5 memory in a dual-channel configuration, providing a memory bandwidth of 83.2 GB/s.

Benchmark results show this is a capable processor. In Cinebench R23, it scores 20851 in multi-core and 2943 in single-core. Its Passmark multithread score is 24389, and it achieves a single-thread score of 3685. The 3DMark tests show scaling from 1874 in 2-thread to 6165 in max-thread, indicating good multi-threading efficiency. The CPU's average benchmark score of 25005 places it in the 77th percentile of all CPUs, with its nearest rival, the AMD Ryzen 5 7500F, being only 0.2% faster.

In the context of Assetto Corsa, the CPU's role is to handle the game's physics simulation, AI, and game logic. The measured FPS data suggests the CPU is not a bottleneck at any resolution. For example, at 1080p Low, the system achieves 106 FPS, which is a high frame rate that indicates the CPU can feed the GPU adequately at lower resolutions. However, because the GPU is so weak, the CPU's performance headroom is never fully utilized. The 16 MB of L3 cache and 12 threads are more than sufficient for a racing simulation that is not heavily multi-threaded. The data indicates that the CPU is performing its role effectively, but the system's overall frame rates are constrained by the Arc B370's inability to render frames quickly enough. If this CPU were paired with a more powerful discrete GPU, the frame rates in this game would be substantially higher.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this hardware depend entirely on the user's priority for frame rate versus visual fidelity. The data provides clear guidance across three resolutions.

For 1080p, the game is playable across all presets. The Low preset yields the best performance at 106 FPS, which is ideal for high-refresh-rate monitors or competitive play. The Medium preset at 75 FPS offers a good balance, providing improved visuals while maintaining a frame rate well above 60 FPS. The High preset at 56 FPS is still playable, but the Ultra preset at 46 FPS is starting to approach the lower limits of smooth gameplay. For the best experience at 1080p, the Medium preset is recommended, as it provides a significant visual upgrade over Low while keeping the average FPS comfortably high. If maximum smoothness is required, Low is the choice.

At 1440p, the options are more constrained. The Low preset at 74 FPS is the only preset that delivers a consistently smooth experience. The Medium preset at 52 FPS is borderline, and the High preset at 39 FPS is not recommended for serious play. The Ultra preset at 32 FPS is effectively unplayable. If a user insists on 1440p, the Low preset is the only viable option, and the visual downgrade is significant.

At 4K, the data shows that no preset provides a good experience. The Low preset at 45 FPS is the best case, but it is below the 60 FPS target. The Medium preset at 32 FPS, High at 24 FPS, and Ultra at 19 FPS are all too slow. The recommendation is to avoid 4K entirely with this combo, as the frame rates are too low for a racing game where consistent performance is critical for control and immersion.

The overall recommendation is to run the game at 1920x1080 with the Medium preset. This provides a playable average of 75 FPS with a minimum of 64 FPS, ensuring no major frame drops. The measured minimum FPS at this setting is 64, which means the game will remain fluid even during intense moments with multiple cars on track. For users with less demanding standards, the High preset at 56 FPS is acceptable, but Medium offers the best balance of visual quality and performance based on the measured data.
