GPU Role

The Intel Arc B390 is the dominant constraint in this system. Built on Intel's 3 nm process with Xe3-LPG architecture, this integrated GPU operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The memory configuration is System Shared, meaning the GPU draws from the same DDR4 pool as the CPU, with bandwidth described as System Dependent rather than a fixed figure.

The GPU's compute resources are modest: 1536 shading units, 48 texture mapping units, 24 render output units, and 12 ray tracing cores. The pixel rate is 60.00 GPixel/s and texture rate is 120.0 GTexel/s, with FP32 performance at 7.680 TFLOPS. The 80 W TDP and IGP slot width confirm this is an integrated solution rather than a discrete card.

Benchmark results place the Arc B390 at the 9th percentile among all GPUs, with a 3DMark Steel Nomad DX12 score of 1482. The nearest rivals in GPU performance are the NVIDIA GeForce GT 520MX (1463, 1.3% ahead), GeForce 800M (1460, 1.5% ahead), GeForce GT 625 OEM (1446, 2.5% ahead), and GeForce GT 710 (1443, 2.7% ahead). This places the Arc B390 in the company of entry-level discrete GPUs from over a decade ago.

The GPU's impact on Assetto Corsa is immediately visible in the measured FPS. At 1080p Low, the system produces 118 FPS, but dropping to Medium reduces the average to 83 FPS, High to 62 FPS, and Ultra to 51 FPS. The scaling from Low to Ultra at 1080p represents a 57% performance reduction, illustrating how quickly the Arc B390's limited shading and texture throughput is overwhelmed by increasing visual complexity.

Settings Recommendations

The measured data points to Low settings as the only preset that consistently delivers high frame rates across all resolutions. At 1080p Low, the system achieves 118 FPS average, which is the only configuration in the entire test matrix that approaches high refresh rate territory. Moving to Medium at 1080p drops to 83 FPS, which remains playable but shows a 30% performance penalty.

For users prioritizing smooth gameplay over visual fidelity, Low at 1080p is the clear choice. The 118 FPS average provides headroom for racing scenarios where frame drops can occur during multi-car battles or complex track sections. The Medium preset at 1080p (83 FPS) offers a middle ground, and it is the only preset with recorded min/max values (70-95 FPS) at this resolution, suggesting relatively stable frame delivery.

At 1440p, Low settings produce 82 FPS average, which is nearly identical to the 1080p Medium result. This suggests that at Low settings, the system has sufficient headroom to handle the resolution increase without significant penalties. However, 1440p Medium drops to 58 FPS (min 49, max 67), which may be borderline for racing simulation where consistent frame delivery matters.

The 4K results are only viable at Low settings, where the system achieves 50 FPS. All other 4K presets fall below 35 FPS, with Ultra producing just 22 FPS. Given that the minimum frame rates at 4K Medium are 30 FPS, the experience would likely feel stuttery during intense moments. The data suggests that users should stick to 1080p or 1440p with Low or Medium settings for the best balance of visual quality and responsiveness.

How This Combo Ranks

This specific combination of AMD Ryzen 7 5800XT and Intel Arc B390 ranks 2566 out of 2897 tested combos for Assetto Corsa, placing it in the bottom 11.4% of all configurations. The ranking reflects the fundamental imbalance between the CPU and GPU components in this pairing.

The Ryzen 7 5800XT is a strong processor that sits at the 81st percentile among all CPUs. Its Cinebench R23 multi-core score of 23794 and single-core score of 3359 demonstrate solid computational capability. The PassMark multi-thread score of 28053 and single-thread score of 3535 further confirm the CPU's strength. In contrast, the Arc B390's 9th percentile GPU ranking creates a situation where the processor is vastly underutilized in gaming workloads.

The nearest CPU rivals to the 5800XT all show similar average scores, with the Ryzen 7 7840H matching at 29868 (0% delta), the Ryzen 7 8845HS and 7840HS both at 29955 (-0.3% delta), and the Ryzen 5 9600X at 29713 (0.6% delta). This cluster of results indicates that CPU performance is not the differentiator in this combo's low ranking; rather, the GPU holds the entire system back.

The combo's rank of 2566 out of 2897 means that 88.6% of tested configurations outperform this pairing in Assetto Corsa. This is consistent with the GPU's position at the 9th percentile, confirming that the Arc B390's integrated graphics capabilities are the primary factor limiting the system's overall gaming performance.

Resolution Scaling

The FPS scaling from 1080p to 4K provides clear evidence of GPU-bound performance. At Low settings, the system delivers 118 FPS at 1080p, 82 FPS at 1440p, and 50 FPS at 4K. This represents a 30.5% drop from 1080p to 1440p and a 39.0% drop from 1440p to 4K. The total reduction from 1080p to 4K is 57.6%, which is consistent with the pixel count increase of roughly 4.5x being partially offset by the GPU's ability to maintain throughput at lower resolutions.

At Medium settings, the scaling pattern is similar but with lower absolute values: 83 FPS at 1080p, 58 FPS at 1440p, and 35 FPS at 4K. The percentage drops are 30.1% from 1080p to 1440p and 39.7% from 1440p to 4K. High settings show 62 FPS at 1080p, 44 FPS at 1440p, and 26 FPS at 4K, with corresponding drops of 29.0% and 40.9%.

The consistent ~30% drop from 1080p to 1440p and ~40% drop from 1440p to 4K across all settings reveals a linear relationship between pixel count and performance. This pattern is characteristic of a GPU that is fully saturated at every resolution tested. If the CPU were the bottleneck, we would expect to see diminishing FPS penalties at higher resolutions as the GPU becomes the constraint. Instead, the proportional scaling indicates the Arc B390 is operating at its limits across the entire resolution range.

Measured FPS Breakdown

At 1920x1080, the system produces its best results. Low settings achieve 118 FPS average, which is the highest number recorded in any test. Medium settings deliver 83 FPS with a minimum of 70 and maximum of 95, providing the only complete frame data at this resolution. High settings reach 62 FPS, while Ultra drops to 51 FPS. The spread from Low to Ultra at 1080p spans 67 FPS, showing a 57% performance range.

The 2560x1440 results show a predictable decline. Low settings produce 82 FPS, nearly matching the 1080p Medium result. Medium settings at 1440p yield 58 FPS with a minimum of 49 and maximum of 67, representing a 30% drop from the 1080p Medium figures. High settings reach 44 FPS, and Ultra falls to 36 FPS. The Low to Ultra spread at 1440p is 46 FPS, or 56% of the Low value.

At 3840x2160, the system struggles to maintain playable frame rates. Low settings achieve 50 FPS, which is the only 4K preset above 40 FPS. Medium settings drop to 35 FPS with a minimum of 30 and maximum of 40, showing tight but low frame delivery. High settings fall to 26 FPS, and Ultra produces just 22 FPS. The 4K Low to Ultra spread is 28 FPS, with Ultra delivering only 44% of the Low settings performance.

CPU Role

The AMD Ryzen 7 5800XT provides substantial computational headroom that the Arc B390 cannot utilize in gaming scenarios. This 8-core, 16-thread processor based on Zen 3 architecture (Vermeer codename) operates at a base clock of 3.80 GHz and boost clock of 4.80 GHz. The 7 nm process from TSMC houses 4,150 million transistors on a 74 mm² die, with a 105 W TDP.

The CPU's cache hierarchy includes 64 KB L1 per core, 512 KB L2 per core, and 32 MB shared L3. Memory support is DDR4 with dual-channel configuration and 51.2 GB/s bandwidth. The processor supports ECC memory and PCIe Gen 4 with 20 lanes. The multiplier is unlocked for overclocking, and the launch MSRP was $249.

Benchmark results confirm the CPU's strength. The Cinebench R23 multi-core score of 23794 and single-core score of 3359 place it well above average. PassMark results show 28053 multi-thread and 3535 single-thread scores. The 3DMark tests show scaling from 959 single-thread to 7683 for 16 threads, indicating effective multi-core utilization.

In Assetto Corsa, the CPU's capabilities are largely untapped. The game's measured frame rates are consistently limited by the GPU, as evidenced by the resolution scaling patterns. The 5800XT's nearest CPU rivals all score within 0.6% of its average benchmark score, showing that CPU-side differences are negligible in this context. The bottleneck is unequivocally the Arc B390's integrated graphics, which cannot translate the CPU's computational power into higher frame rates.
