Assetto Corsa

The AMD Ryzen 9 7900X paired with the Intel Arc B370 produces a remarkably constrained gaming experience in Assetto Corsa, a 2014 racing simulation that remains popular in the benchmark database. This combination ranks 2669th out of 2897 tested combos, placing it in the bottom 8% of all CPU-GPU pairings measured for this title. The data shows a system that is overwhelmingly limited by its graphics component, with the Ryzen 9 7900X’s substantial processing power largely untapped at every resolution and settings level tested.

How This Combo Ranks

The combo rank of 2669 out of 2897 tested combinations places this pairing firmly in the lower percentile of systems evaluated for Assetto Corsa. This position is not a reflection of the CPU’s capabilities but rather a direct consequence of the GPU’s performance tier. The Intel Arc B370 sits at the 5th percentile among all GPUs in the database, with an average benchmark score of 1184 from a single 3DMark Steel Nomad DX12 test. This places it in direct competition with legacy graphics solutions from over a decade ago. The nearest GPU rivals tell a clear story: the ATI Mobility Radeon HD 5570 scores 1186 (a 0.2% delta), the ATI Radeon HD 5770 scores 1190 (0.5% delta), the AMD Radeon HD 7650M scores 1192 (0.7% delta), and the AMD FirePro M2000 scores 1168 (1.4% delta). The Arc B370 is effectively trading blows with hardware from the early 2010s, which explains why this combo languishes at 2669th place.

In contrast, the Ryzen 9 7900X is a top-tier processor. Its average benchmark score of 53288 places it at the 91st percentile among all CPUs. The nearest CPU rivals are all server or high-end desktop parts: the AMD EPYC 7313P averages 53206 (0.2% delta), the Intel Xeon Phi 7290 averages 53469 (-0.3% delta), the Intel Xeon 634 averages 52974 (0.6% delta), and the Intel Core i7-14700F averages 53620 (-0.6% delta). The 7900X is within 0.6% of all these rivals, indicating that its processing power is competitive with enterprise-class silicon. The massive gulf between the CPU’s 91st percentile standing and the GPU’s 5th percentile standing creates a fundamental imbalance that defines every benchmark result in this pairing.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Panther Lake chip, built on Intel’s 3 nm process using the Xe3-LPG architecture. Its specifications reveal its limited nature: 1280 shading units, 40 texture mapping units, 20 render output units, and 10 ray tracing cores. The GPU operates with a base clock of 300 MHz and a boost clock of 2400 MHz, producing a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The FP32 performance is 6.144 TFLOPS, with FP16 at 12.29 TFLOPS (2:1). The thermal design power is just 25 W, and it uses no power connectors, confirming its integrated nature.

Memory is the most telling limitation. The Arc B370 uses system shared memory, with no dedicated VRAM allocation. The memory type is system shared, the bus width is system shared, and the bandwidth is system dependent. This means the GPU must compete with the CPU for access to the same DDR5 memory pool, which is a severe handicap in a game like Assetto Corsa that benefits from consistent memory bandwidth. The 7900X supports dual-channel DDR5 with a memory bandwidth of 83.2 GB/s, but this is shared across both processing units.

The Arc B370’s benchmark presence is minimal, with only one recorded test: 3DMark Steel Nomad DX12 at a score of 1184. This single data point places it at the 5th percentile of all GPUs. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, meaning it has the API feature set for modern games, but the raw throughput is simply insufficient. In Assetto Corsa, which is not a graphically demanding title by modern standards, the Arc B370 still becomes the definitive bottleneck, as evidenced by the measured FPS data across all resolutions.

Resolution Scaling

The measured FPS data for this combo shows a clear and predictable pattern of performance degradation as resolution increases. At 1080p with Low settings, the combo achieves 106 FPS average. Moving to 1440p Low, the average drops to 74 FPS, a 30% reduction. At 4K Low, the average falls to 45 FPS, which is a 58% reduction from the 1080p figure. This scaling pattern indicates that the GPU is the limiting factor, as the frame rate drops nearly linearly with the increase in pixel count.

The Medium settings data provides additional insight. At 1080p Medium, the average is 75 FPS with a minimum of 64 and a maximum of 86. At 1440p Medium, the average drops to 52 FPS with a minimum of 44 and a maximum of 60. At 4K Medium, the average falls to 32 FPS with a minimum of 27 and a maximum of 36. The consistent downward progression across all three resolutions confirms that the Arc B370’s rendering throughput is the primary constraint. The Ryzen 9 7900X, with its 12 cores and 24 threads, is not the limiting factor here, as its processing power remains largely idle.

High settings show a similar trajectory. At 1080p High, the average is 56 FPS. At 1440p High, it drops to 39 FPS. At 4K High, it falls to 24 FPS. The Ultra settings are the most demanding, with 1080p Ultra averaging 46 FPS, 1440p Ultra averaging 32 FPS, and 4K Ultra averaging just 19 FPS. The pattern across all settings is unmistakable: this combo cannot maintain playable frame rates at higher resolutions, and even at 1080p, only Low and Medium settings produce consistently smooth results.

The scaling behavior also reveals that the CPU is not a bottleneck at any resolution. If the Ryzen 9 7900X were the limiting factor, the frame rates would remain relatively constant across resolutions, as the CPU workload does not scale significantly with pixel count. Instead, the FPS drops substantially with each resolution increase, which is the hallmark of a GPU-bound scenario. The shared memory architecture of the Arc B370 likely exacerbates this, as higher resolutions require more memory bandwidth, further straining the system.

Settings Recommendations

The measured rows provide clear guidance on which settings preset offers the best experience for this combo. At 1080p, Low settings deliver 106 FPS average, which is smooth and responsive. Medium settings at 1080p deliver 75 FPS average, with a minimum of 64 FPS, which is still playable and offers improved visual quality. High settings at 1080p drop to 56 FPS average, which is borderline for a racing simulation where consistent frame pacing matters. Ultra settings at 1080p fall to 46 FPS average, which is marginal.

At 1440p, the situation becomes more constrained. Low settings deliver 74 FPS average, which is acceptable. Medium settings deliver 52 FPS average, which is playable but not ideal for a racing game. High settings drop to 39 FPS average, and Ultra falls to 32 FPS average, both of which are suboptimal for competitive driving. At 4K, no settings preset produces acceptable results. Low settings average 45 FPS, Medium averages 32 FPS, High averages 24 FPS, and Ultra averages 19 FPS.

The best experience per the measured rows is 1080p with Medium settings. This preset balances visual fidelity with performance, delivering 75 FPS average with a minimum of 64 FPS and a maximum of 86 FPS. The minimum frame rate of 64 FPS indicates that the combo can maintain playable performance even during demanding scenes. Low settings at 1080p offer higher average FPS at 106, but the visual quality reduction may not be worth the extra performance headroom, especially since Medium already provides a stable experience. For users who prioritize frame rate above all else, 1080p Low is the safer choice, but Medium is the recommended balance.

Measured FPS Breakdown

The measured FPS data for this combo, while limited in some cells, provides a comprehensive view of performance across resolutions and settings. The dataset includes average FPS for all 12 combinations, with minimum and maximum values available for the Medium settings at each resolution.

At 1920x1080, the results are as follows: Low settings produce 106 FPS average, Medium settings produce 75 FPS average with a minimum of 64 and a maximum of 86, High settings produce 56 FPS average, and Ultra settings produce 46 FPS average. The Medium settings data shows a 22 FPS spread between minimum and maximum, indicating some scene-dependent variability but generally stable performance.

At 2560x1440, the results show a notable drop. Low settings produce 74 FPS average, Medium settings produce 52 FPS average with a minimum of 44 and a maximum of 60, High settings produce 39 FPS average, and Ultra settings produce 32 FPS average. The Medium settings spread narrows to 16 FPS, suggesting that the GPU is becoming more consistently saturated as resolution increases.

At 3840x2160, the performance becomes marginal. Low settings produce 45 FPS average, Medium settings produce 32 FPS average with a minimum of 27 and a maximum of 36, High settings produce 24 FPS average, and Ultra settings produce 19 FPS average. The Medium settings spread at 4K is 9 FPS, indicating that the GPU is nearly always at its limit. The minimum FPS of 27 at 4K Medium falls below the 30 FPS threshold commonly considered the minimum for playable frame rates.

The progression from 1080p to 4K shows a consistent halving of performance at each resolution step for most settings. For example, Low settings drop from 106 FPS at 1080p to 74 FPS at 1440p to 45 FPS at 4K. High settings drop from 56 FPS at 1080p to 39 FPS at 1440p to 24 FPS at 4K. This pattern underscores the GPU-bound nature of the combo, as the CPU’s performance headroom does not compensate for the GPU’s limitations.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture, codenamed Raphael. It operates with a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with a thermal design power of 170 W. The processor is built on TSMC’s 5 nm process with 13,140 million transistors across a dual-chiplet design with a die size of 2x 71 mm². The cache hierarchy includes 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. The CPU supports DDR5 memory with a dual-channel bus and an 83.2 GB/s memory bandwidth, and it includes integrated Radeon Graphics as a fallback.

The 7900X’s benchmark results demonstrate its high-end positioning. In Cinebench R23, it scores 29300 in multicore and 2016.5 in single-core. In Geekbench, it scores 19267 in multicore and 2617 in single-core. The PassMark multithread score is 51406, with a single-thread score of 4238. The 3DMark results show a progression from 1093 in single-thread to 2137 in 2-thread to 4151 in 4-thread to 7798 in 8-thread to 10972 in 16-thread to 12536 in max-thread. These numbers indicate a processor that excels in both single-threaded and multi-threaded workloads.

In Assetto Corsa, the CPU’s role is minimal due to the GPU bottleneck. The game is not heavily multi-threaded, and the 7900X’s strong single-thread performance, as evidenced by its 3DMark single-thread score of 1093 and Cinebench R23 single-core score of 2016.5, is more than sufficient for the game’s physics and AI calculations. The 12 cores and 24 threads are largely underutilized, as Assetto Corsa does not scale to use that many threads effectively. The CPU’s 91st percentile ranking among all CPUs, with an average benchmark score of 53288, places it in the top tier of processors, but this capability is wasted in this pairing.

The memory system also plays a role, though not a limiting one. The 7900X’s dual-channel DDR5 support with 83.2 GB/s bandwidth is shared with the Arc B370’s system shared memory. While this shared bandwidth could theoretically cause contention, the measured FPS data does not show signs of memory-related stuttering. The minimum FPS values for Medium settings at all resolutions are within reasonable ranges of the averages, suggesting that memory bandwidth is not a critical constraint. The CPU’s 64 MB of L3 cache likely helps mitigate some memory latency issues.

The Ryzen 9 7900X’s nearest CPU rivals include the AMD EPYC 7313P, which scores 53206 (0.2% delta), and the Intel Core i7-14700F, which scores 53620 (-0.6% delta). These results confirm that the 7900X is competitive with both server and desktop flagship processors. However, none of this processing power translates into higher frame rates in Assetto Corsa because the Arc B370 simply cannot render frames fast enough to utilize the CPU’s capabilities. The combo rank of 2669 out of 2897 is a direct result of this imbalance, and no amount of CPU performance can overcome the GPU’s fundamental limitations.
