Assetto Corsa

Assetto Corsa is a racing simulation that scales heavily with GPU load, and the combination of the Intel Core i5-12600KF and the Intel Arc B370 shows a clear performance ceiling. The data indicates that this system is viable for playable frame rates at lower resolutions and settings, but it struggles to maintain smooth gameplay as resolution and graphical fidelity increase. The benchmark results show a predictable pattern of performance degradation, with the most significant drops occurring at 4K Ultra settings.

Resolution Scaling

The measured FPS data reveals a steep performance curve as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate drops from 56 FPS at 1080p to 39 FPS at 1440p, and finally to 24 FPS at 4K. This represents a 31% decrease from 1080p to 1440p and a further 38% decrease from 1440p to 4K. The scaling indicates that the GPU is the primary limiting factor, as the performance penalty for additional pixels is severe.

The pattern is consistent across all settings levels. At Low settings, the system achieves 106 FPS at 1080p, which drops to 74 FPS at 1440p and 45 FPS at 4K. The 1080p to 1440p drop is 30%, while the 1440p to 4K drop is 39%. At Medium settings, the system delivers 75 FPS at 1080p, 52 FPS at 1440p, and 32 FPS at 4K. This shows that even when the CPU has less work to do, the GPU's rendering capabilities are exhausted quickly as pixel count increases.

The most telling data point is at Ultra settings, where the system manages only 46 FPS at 1080p, 32 FPS at 1440p, and 19 FPS at 4K. The 4K Ultra result is below the threshold for smooth, playable performance in a racing game, suggesting that this combination is not suited for maximum quality at high resolutions. The resolution scaling pattern confirms that the Arc B370 is the bottleneck, as the consistent percentage drops across settings indicate a GPU-bound scenario rather than CPU limitations.

GPU Role

The Intel Arc B370 is a low-power integrated GPU with a 25 W TDP, operating at a base clock of 300 MHz and a boost clock of 2400 MHz. It features 1280 shading units, 40 texture mapping units, and 20 render output units, along with 10 ray tracing cores. The memory configuration is system shared, with bandwidth described as system dependent, meaning the GPU relies on the host system's memory rather than dedicated VRAM. This architecture explains the performance limitations observed in the measured data.

The GPU's compute capabilities are modest, with a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The FP32 performance is rated at 6.144 TFLOPS, which is a moderate figure for a modern integrated solution. The 3DMark Steel Nomad DX12 benchmark score of 1184 places the Arc B370 in the 5th percentile of all GPUs, indicating that it performs near the bottom of the tested pool. Its nearest rivals in the benchmark database include the ATI Mobility Radeon HD 5570 with a score of 1186 and a deltaPct of -0.2%, and the AMD Radeon HD 7650M with a score of 1192 and a deltaPct of -0.7%. These comparisons show that the Arc B370 is performing at a level comparable to older, low-end mobile graphics solutions.

The lack of dedicated VRAM means that the GPU's performance is tied to the system's memory bandwidth and latency. In Assetto Corsa, this manifests as a sharp drop in frame rates at higher resolutions, where the GPU must fetch more texture data and geometry from shared system memory. The data shows that the GPU can handle 1080p Low settings with 106 FPS, but at 4K Ultra, the frame rate collapses to 19 FPS, a 82% reduction. This indicates that the shared memory architecture is a significant constraint for higher-resolution gaming.

How This Combo Ranks

The combination of the Intel Core i5-12600KF and Intel Arc B370 ranks 2669 out of 2897 tested combos in Assetto Corsa. This places it in the bottom 8% of all tested configurations, reflecting the GPU's low performance ceiling. The ranking is heavily influenced by the Arc B370's limited capabilities, as the CPU is a relatively strong performer with a 79th percentile ranking among all CPUs.

The CPU's average benchmark score of 27799 is close to its nearest rivals, with the Intel Core i9-10900K scoring 27872 (a deltaPct of -0.3%) and the AMD Ryzen 7 5800X3D scoring 27896 (a deltaPct of -0.3%). This indicates that the i5-12600KF is competitive with older high-end processors, but the GPU's 5th percentile ranking drags the overall combo rank down. The data suggests that pairing the i5-12600KF with a more capable GPU would yield a significantly higher ranking, but as configured, the system is limited by its graphics solution.

In practical terms, the combo rank of 2669 out of 2897 means that most other tested combinations deliver better performance in Assetto Corsa. The system can handle the game at lower settings and resolutions, but it is not a configuration that would be recommended for users seeking a high-quality racing experience. The ranking underscores the importance of GPU selection in this title, as the CPU's strengths are largely negated by the GPU's weaknesses.

CPU Role

The Intel Core i5-12600KF is a 10-core, 16-thread processor based on the Alder Lake architecture, with a base clock of 3.70 GHz and a boost clock of 4.90 GHz. It has a 20 MB shared L3 cache and supports dual-channel DDR4 or DDR5 memory. The CPU's benchmark results show strong multi-threaded and single-threaded performance, with a Cinebench R23 multicore score of 23391 and a single-core score of 3302. In 3DMark, the CPU scores 7956 in the 16-thread test and 1016 in the single-thread test.

In Assetto Corsa, the CPU's role is to handle physics calculations, AI, and game logic, which are typically less demanding than GPU rendering. The data shows that the CPU is not the bottleneck in this combination, as frame rates scale consistently with resolution changes. At 1080p Low, the system achieves 106 FPS, which indicates that the CPU can feed the GPU with enough data to sustain high frame rates at lower resolutions. The CPU's 79th percentile ranking and its competitive benchmark scores against rivals like the Intel Core i9-10900K and AMD Ryzen 7 5800X3D suggest that it is more than capable for this game.

The CPU's 10 cores and 16 threads provide ample processing power for Assetto Corsa's simulation aspects, and the high boost clock of 4.90 GHz ensures responsive single-threaded performance. The measured FPS data shows that the CPU is not limiting performance even at 1080p Low, where the system hits 106 FPS. If the GPU were weaker, we would expect to see frame rates plateau at lower resolutions, but the data shows a clear GPU-bound scaling pattern. This indicates that the i5-12600KF is a solid foundation for this system, and any performance limitations are attributable to the Arc B370.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system's performance across three resolutions and four settings levels. At 1920x1080, the system delivers 106 FPS at Low settings, 75 FPS at Medium, 56 FPS at High, and 46 FPS at Ultra. The Medium setting has a minimum of 64 FPS and a maximum of 86 FPS, showing a 22 FPS variance. These results indicate that 1080p is the most viable resolution for this combination, with playable frame rates at all settings except perhaps Ultra, which dips close to the 40 FPS range.

At 2560x1440, the performance drops significantly. Low settings yield 74 FPS, Medium yields 52 FPS with a minimum of 44 FPS and a maximum of 60 FPS, High yields 39 FPS, and Ultra yields 32 FPS. The Medium setting's minimum of 44 FPS suggests that there may be occasional stuttering in demanding scenes. High and Ultra settings are below the 60 FPS threshold, making them less suitable for smooth gameplay. The 1440p resolution is playable only at Low settings, where the frame rate remains above 70 FPS.

At 3840x2160, the system struggles to maintain playable performance. Low settings achieve 45 FPS, Medium achieves 32 FPS with a minimum of 27 FPS and a maximum of 36 FPS, High achieves 24 FPS, and Ultra achieves 19 FPS. The Medium setting's minimum of 27 FPS indicates that the system will experience noticeable frame drops during races. None of the 4K settings reach 60 FPS, and even Low settings fall below the 50 FPS mark. This makes 4K gaming impractical for this combination, particularly at higher quality presets. The data clearly shows that the Arc B370 is the limiting factor, with the CPU's performance remaining sufficient across all tested configurations.
