Assetto Corsa

The AMD Ryzen 7 7700 paired with the Intel Arc B370 presents a peculiar combination in Assetto Corsa, a racing simulation from 2014. The processor is a modern 8-core, 16-thread Zen 4 part, while the graphics solution is an integrated-class chip based on the Xe3-LPG architecture. The measured frames per second across resolutions and settings reveal a system that is firmly constrained by its graphics component, with the CPU’s substantial multi-threaded capabilities remaining largely underutilized in this title.

Resolution Scaling

The data shows a steep and consistent decline in average FPS as resolution increases, a pattern that points directly at the Intel Arc B370 as the limiting factor. At 1920x1080 with Low settings, the combo produces 106 FPS. Moving to 2560x1440 at the same Low preset drops that figure to 74 FPS, a reduction of 32 FPS or roughly 30%. Scaling further to 3840x2160 at Low yields 45 FPS, which is 61 FPS below the 1080p result and represents a 42.5% drop from the 1440p figure. This linear degradation with pixel count is characteristic of a GPU-bound scenario, where the rendering workload scales directly with the number of pixels being processed.

The pattern holds across other settings. At Medium quality, the average FPS goes from 75 at 1080p to 52 at 1440p, then down to 32 at 4K. The deltas are 23 FPS and 20 FPS respectively. At High settings, the sequence is 56, 39, and 24 FPS. The step from 1440p to 4K at High costs 15 FPS, while the step from 1080p to 1440p costs 17 FPS. Even at Ultra, the lowest playable tier, the numbers fall from 46 at 1080p to 32 at 1440p and finally to 19 at 4K. The proportional losses are similar at each quality level, reinforcing that resolution, not settings complexity, is the dominant variable.

This behavior indicates that the Arc B370’s fill rate and memory bandwidth—both tied to system shared memory—are saturated well before the Ryzen 7 7700’s processing power becomes relevant. The CPU, with a boost clock of 5.30 GHz and a 32 MB shared L3 cache, can feed frames far faster than this GPU can render them. The benchmark results suggest that even at 1080p Low, the graphics chip is working near its ceiling, as the 106 FPS figure is modest for a 2014 racing title on modern hardware. If the Ryzen 7 7700 were the bottleneck, we would expect to see much higher FPS at lower resolutions, with a plateau forming as the CPU limit is reached. Instead, the FPS falls almost perfectly with pixel count, which is the signature of a pure GPU constraint.

The implication for users is straightforward. The Intel Arc B370 is the component that dictates performance in Assetto Corsa, and any attempt to improve frame rates must target the graphics side. Reducing resolution offers the most predictable gains, as the data shows a near-linear relationship between pixel count and FPS. Meanwhile, the Ryzen 7 7700’s 8 cores and 16 threads remain idle, as the game’s simulation logic does not appear to stress the processor in this configuration.

FAQ

Q: What is the best average FPS achievable with this CPU and GPU combo in Assetto Corsa?

GPU Role

The Intel Arc B370 is the decisive component in this pairing. Its specifications show a chip designed for integrated use, with a base clock of 300 MHz and a boost clock of 2400 MHz. The memory is marked as "System Shared," meaning it relies on the host system’s DDR5 RAM rather than dedicated VRAM. Bandwidth is described as "System Dependent," which introduces variability based on the platform’s memory configuration. In this case, the Ryzen 7 7700 supports dual-channel DDR5 with a theoretical bandwidth of 83.2 GB/s, but the Arc B370’s shared memory architecture means it competes with the CPU for the same memory resources.

The GPU’s compute resources are modest: 1280 shading units, 40 texture mapping units, and 20 raster output units. The pixel rate is 48.00 GPixel/s and the texture rate is 96.00 GTexel/s. Floating point performance is rated at 6.144 TFLOPS for FP32 and 12.29 TFLOPS for FP16. These figures place the Arc B370 in the bottom tier of graphics processors, as evidenced by its 5th percentile ranking among all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570, which scores 1186 in 3DMark Steel Nomad DX12 versus the Arc B370’s 1184, a difference of -0.2%. This is not a chip built for high-refresh gaming; it is an integrated part meant for basic display output and light workloads.

In Assetto Corsa, the GPU’s limitations become apparent immediately. The highest average FPS across all tested configurations is 106 at 1080p Low. The Ultra preset at 4K produces just 19 FPS. These numbers reflect a GPU that cannot keep pace with the CPU’s ability to deliver draw calls and simulation data. The Ryzen 7 7700, with its 5.30 GHz boost clock and 87th percentile ranking among all CPUs, is more than capable of handling the game’s physics and AI. The bottleneck is the rendering pipeline, where the Arc B370’s 20 ROPs and shared memory bandwidth struggle to fill the screen at higher resolutions and settings.

The lack of dedicated VRAM is particularly impactful in a racing game with detailed tracks and car models. At 4K Ultra, the system must store texture data in system memory, and the bandwidth limitations of shared memory become a severe constraint. The measured FPS at 4K Ultra is 19, which is only slightly above a slideshow. Even at 1080p Medium, the average FPS is 75, with a minimum of 64 and a maximum of 86. These frame times suggest inconsistent performance, likely due to memory contention between the CPU and GPU.

For users, the takeaway is that the Arc B370 is the component to upgrade if higher frame rates are desired. The Ryzen 7 7700 has ample headroom, as shown by its strong synthetic benchmarks and the fact that FPS scales with resolution rather than CPU-bound logic. The GPU’s 3 nm process node and Xe3-LPG architecture are efficient for its class, but they do not compensate for the fundamental lack of dedicated graphics memory and raw throughput.

How This Combo Ranks

The combination of the AMD Ryzen 7 7700 and Intel Arc B370 ranks 3427 out of 3712 tested combos in Assetto Corsa. This places it in the 92nd percentile from the bottom, meaning only 285 combinations performed worse. The rank is a direct reflection of the Arc B370’s low graphics capabilities, as the CPU is a high-end part that would typically rank much higher in gaming tests. The discrepancy between the CPU’s 87th percentile standing among all processors and the combo’s near-bottom ranking highlights how severely the GPU drags down the overall result.

The GPU’s own percentile is 5, which is consistent with the combo’s poor ranking. The nearest rivals to the Arc B370 in the GPU benchmark database are all legacy or low-end parts. For instance, the ATI Mobility Radeon HD 5570 has an average score of 1186, a mere 0.2% higher than the Arc B370’s 1184. The AMD Radeon HD 7650M scores 1192, 0.7% higher. These are not modern gaming GPUs by any stretch, yet they are the closest peers to the Arc B370 in terms of raw compute performance.

In the context of Assetto Corsa, this ranking means the combo will struggle to deliver a smooth experience at most settings. The game itself is a 2014 release, but it still requires a reasonable GPU to render modern tracks and car models at high resolutions. The measured FPS data confirms that the combo is only viable at 1080p with Low or Medium settings, and even then, the frame rates are not exceptional. At 1440p and 4K, the experience degrades to the point of being unplayable for most users.

The CPU’s synthetic benchmarks show it is a capable part, with a Cinebench R23 multi-core score of 18760 and a single-core score of 1930. The Geekbench multi-core score is 15371, and the single-core score is 2525. These numbers indicate that the Ryzen 7 7700 is not the source of the combo’s poor ranking. Instead, the Arc B370’s 5th percentile GPU score is the primary driver. The rank of 3427 out of 3712 is a stark illustration of how a weak GPU can neutralize a strong CPU in gaming workloads.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average FPS of 106, which is the only triple-digit score in the entire dataset. Medium settings drop to 75 FPS, with a minimum of 64 and a maximum of 86. High settings yield 56 FPS, and Ultra falls to 46 FPS. The gradient from Low to Ultra at 1080p is a 60 FPS swing, demonstrating that the GPU’s fill rate is severely taxed by higher quality presets.

Moving to 2560x1440, the performance drops significantly. Low settings average 74 FPS, which is still playable but 30% lower than the 1080p Low result. Medium settings average 52 FPS, with a minimum of 44 and a maximum of 60. High settings produce 39 FPS, and Ultra drops to 32 FPS. None of these 1440p results reach the 60 FPS target, and the Ultra preset is borderline unplayable.

At 3840x2160, the combo struggles to maintain playable frame rates. Low settings average 45 FPS, which is the best 4K result. Medium settings average 32 FPS, with a minimum of 27 and a maximum of 36. High settings drop to 24 FPS, and Ultra falls to 19 FPS. The 4K Ultra result is less than one-fifth of the 1080p Low result, highlighting the GPU’s inability to handle high pixel counts.

The Medium settings rows are the only ones with min and max FPS data. At 1080p Medium, the range is 64 to 86 FPS, a spread of 22 FPS. At 1440p Medium, the range is 44 to 60 FPS, a spread of 16 FPS. At 4K Medium, the range is 27 to 36 FPS, a spread of 9 FPS. The narrowing range at higher resolutions suggests that the GPU is consistently saturated, with less variance in frame times as the rendering load increases.

For all other settings, only average FPS is provided. The data shows a clear hierarchy: Low > Medium > High > Ultra at every resolution. The relative gaps between settings are consistent, with Low typically delivering roughly 2.3 to 2.4 times the FPS of Ultra at the same resolution. For example, at 1080p, Low is 106 FPS and Ultra is 46 FPS, a factor of 2.3. At 1440p, Low is 74 FPS and Ultra is 32 FPS, a factor of 2.3. At 4K, Low is 45 FPS and Ultra is 19 FPS, a factor of 2.4.

Settings Recommendations

Based on the measured FPS, the only configuration that offers a smooth racing experience is 1920x1080 with Low settings, which produces 106 FPS. This is the sole preset that clears the 100 FPS mark, making it ideal for high-refresh-rate displays. The 1080p Medium preset, at 75 FPS, is also viable for users who can tolerate a slight drop in frame rate for improved visual fidelity. The minimum FPS of 64 at this setting ensures that the experience remains fluid even during intense moments.

For 1440p users, the Low preset is the only option that exceeds 60 FPS, at 74 FPS. The Medium preset at 52 FPS is playable but may feel less smooth, particularly in fast corners where frame time spikes could occur. The High and Ultra presets at 1440p, with 39 FPS and 32 FPS respectively, are not recommended for competitive racing, as the low frame rates will hinder responsiveness.

At 4K, none of the presets deliver acceptable performance. The Low preset at 45 FPS is marginally playable, but the Medium preset at 32 FPS and below will result in a stuttering, unresponsive experience. The data suggests that 4K is not a viable resolution for this combo, and users should drop to 1440p or 1080p to achieve playable frame rates.

The Ultra preset is the least recommended across all resolutions. It produces 46 FPS at 1080p, 32 FPS at 1440p, and 19 FPS at 4K. These figures are all below the 60 FPS target, and the visual improvements over High are unlikely to compensate for the reduced smoothness. The High preset offers a better balance, with 56 FPS at 1080p, but it still falls short of 60 FPS.

Given the GPU’s limitations, the optimal strategy is to prioritize frame rate over visual quality. Users should select the Low preset at their native resolution, then adjust to Medium if the resulting FPS allows. The data shows that Medium at 1080p (75 FPS) is a better experience than Low at 1440p (74 FPS) in terms of visual quality, but the frame rates are nearly identical. For users with a 1080p display, Medium is the sweet spot. For 1440p users, Low is the only acceptable choice. For 4K users, the recommendation is to lower the resolution to 1440p or 1080p, as no 4K preset delivers a consistently smooth experience.
