Assetto Corsa

The Intel Core i7-14700F paired with the Intel Arc B390 presents a highly unusual configuration for Assetto Corsa, a 2014 racing simulation. The data shows a system where a top-tier 20-core CPU is paired with an integrated-class GPU solution, resulting in a bottleneck that is entirely one-sided. This analysis breaks down the measured performance, focusing on how the GPU limits the experience across resolutions and settings, and what the CPU contributes to the overall picture.

Resolution Scaling

The FPS data reveals a classic pattern of GPU-bound scaling. As resolution increases, the average frame rate drops significantly, indicating that the Intel Arc B390 is the primary limiting component. At 1080p with Low settings, the combo achieves 118 FPS. Moving to 1440p Low drops the average to 82 FPS, a 30% reduction. At 4K Low, the average falls further to 50 FPS, which is a 39% drop from the 1440p figure and a 58% drop from 1080p. This steep decline is the hallmark of a GPU struggling with pixel throughput, not a CPU limitation.

The scaling pattern holds across other settings. For High settings, the average FPS goes from 62 at 1080p to 44 at 1440p (a 29% drop) and then to 26 at 4K (a 41% drop from 1440p). This consistent percentage decrease as resolution climbs confirms that the Arc B390's rendering capabilities are saturated. The CPU's performance headroom is irrelevant here; the GPU is unable to feed frames fast enough to keep up with the i7-14700F's processing power.

This behavior suggests that for 1080p gaming, the combo can deliver playable frame rates at lower settings, but it is not a high-refresh-rate solution. At 1440p, the user must compromise on settings to maintain smoothness. At 4K, the system is largely unsuitable for serious play, with even Low settings only producing an average of 50 FPS. The data indicates that the GPU's memory bandwidth, which is "System Dependent," becomes a critical constraint at higher resolutions, as the integrated graphics must share system memory, further limiting performance.

GPU Role

The Intel Arc B390 is the decisive factor in this configuration's gaming performance. Its benchmark results are modest, to say the least. The GPU scores 1482 in the 3DMark Steel Nomad DX12 test, which places it in the 9th percentile of all GPUs. This is a very low score, and the nearest rivals in the data are all older, low-end NVIDIA parts: the GeForce GT 520MX (1.3% ahead), the GeForce 800M (1.5% ahead), the GeForce GT 625 OEM (2.5% ahead), and the GeForce GT 710 (2.7% ahead). This places the Arc B390 firmly in entry-level territory, and the measured FPS reflects this.

The GPU's specifications support this analysis. It has a base clock of 300 MHz and a boost clock of 2500 MHz, which is a wide range indicating a power-managed mobile or integrated design. Its memory is "System Shared," meaning it has no dedicated VRAM and relies on system memory, making its bandwidth "System Dependent." With 1536 shading units and 24 ROPs, the theoretical pixel rate is 60.00 GPixel/s, but the shared memory and low overall performance clearly hamstring the chip. The fact that it is an IGP (Integrated Graphics Processor) with a 80 W TDP and no power connectors confirms it is not a discrete solution.

In practice, this means the GPU is the sole reason for the low frame rates. The data shows that even at 1080p Ultra, the average FPS is only 51, and at 4K Ultra, it plummets to 22 FPS. The GPU's architecture, Xe3-LPG, supports modern APIs like DirectX 12 Ultimate and Vulkan 1.4, but its raw computational power is insufficient for demanding tasks at high resolutions. The measured 7.680 TFLOPS of FP32 performance is simply not enough to drive Assetto Corsa at high settings with smooth frame rates, especially when compared to what the CPU can handle.

How This Combo Ranks

The data places this specific CPU-GPU combination in the 2566th position out of 2897 tested combos for Assetto Corsa. This ranking, which is in the bottom 11% of all combinations, is a direct result of the massive imbalance between the CPU and GPU. While the CPU is a high-end part, the GPU is a very low-end one, and the combo's overall standing is dragged down by the GPU's inability to deliver adequate performance.

This rank is not a reflection of the CPU's capabilities. The Intel Core i7-14700F, on its own, is a powerful processor. Its average benchmark score is 53620, placing it in the 91st percentile of all CPUs. It is a top-tier part, and its nearest rivals are all high-end server or workstation chips, such as the Intel Xeon 6505P (0.2% behind), the Intel Xeon Phi 7290 (0.3% ahead), and the AMD Ryzen 9 7900X (0.6% ahead). The CPU is clearly not the problem in this combo.

The combo's low rank is entirely attributable to the GPU. The Arc B390's 9th percentile ranking shows that it is one of the weakest GPUs in the database. When paired with a CPU that is in the 91st percentile, the result is a system that is severely bottlenecked. The data suggests that this combination is not a balanced gaming platform. It is a pairing that would only be seen in a system where the GPU is a placeholder or where the user is not prioritizing gaming performance, as the CPU's potential is almost entirely wasted in this configuration.

Measured FPS Breakdown

The measured FPS data provides a detailed look at the system's performance across three resolutions and four settings levels. The following is a complete breakdown of the average frame rates:

• 1920x1080 (1080p):
• Low: 118 FPS average
• Medium: 83 FPS average (min 70, max 95)
• High: 62 FPS average
• Ultra: 51 FPS average

• 2560x1440 (1440p):
• Low: 82 FPS average
• Medium: 58 FPS average (min 49, max 67)
• High: 44 FPS average
• Ultra: 36 FPS average

• 3840x2160 (4K):
• Low: 50 FPS average
• Medium: 35 FPS average (min 30, max 40)
• High: 26 FPS average
• Ultra: 22 FPS average

The data shows a clear hierarchy. At 1080p, the system can achieve a playable 60+ FPS at High settings (62 FPS) and is very smooth at Low settings (118 FPS). However, dropping to Medium settings yields 83 FPS, which is still good. At 1440p, the system struggles to maintain 60 FPS, with only Low settings (82 FPS) achieving that mark. High settings at 1440p drop to 44 FPS, which is borderline for playable. At 4K, the system is not viable for competitive or smooth gameplay, as even Low settings only reach 50 FPS, and High/Ultra settings drop to 26 and 22 FPS, respectively.

The Medium settings data provides the only min/max FPS figures. At 1080p Medium, the range is 70 to 95 FPS. At 1440p Medium, it is 49 to 67 FPS. At 4K Medium, it is 30 to 40 FPS. These ranges show that the frame pacing is relatively consistent, but the average is too low at higher resolutions. The lack of min/max data for other settings suggests the benchmark tool only captured these for Medium, but the averages alone tell the story of a GPU that is overworked at 1440p and 4K.

CPU Role

The Intel Core i7-14700F is a powerhouse that is entirely underutilized in this gaming context. With 20 cores and 28 threads, it is a processor designed for heavy multitasking and productivity workloads. Its benchmark scores are exceptional: a Cinebench R23 multi-core score of 35122 and a single-core score of 4958. This places it in the 91st percentile of all CPUs, showing that it can handle any task thrown at it. The data from PassMark confirms this, with a multi-thread score of 41317 and a single-thread score of 4257.

However, in Assetto Corsa, the GPU is the bottleneck, so the CPU's role is reduced to simply feeding the GPU with data. The high boost clock of 5.40 GHz and the large 33 MB of shared L3 cache are more than sufficient for this game. The game's simulation and physics engine can be CPU-intensive, but with 20 cores, the i7-14700F has ample headroom. The data shows that the CPU is not the limiting factor; the frame rates are set by the GPU's rendering speed.

The CPU's architecture is Raptor Lake-R on a 10 nm process, and it supports both DDR4 and DDR5 memory. This flexibility is a plus, but the memory bus is dual-channel, which is standard. The CPU's performance percentile, 91, compared to the GPU's 9, highlights the massive gap in capability. In this combo, the CPU is like a race car engine attached to bicycle wheels. The engine has enormous power, but the wheels cannot transfer it to the road. The measured FPS is a direct result of the GPU's limitations, not the CPU's. The CPU's 65 W TDP and 2.10 GHz base clock are irrelevant to the gaming results, as it is never the component being stressed.

FAQ

Q: Why is the 4K performance so low even on Low settings?

A: The Intel Arc B390 is a very weak GPU, ranking in the 9th percentile overall. At 4K, the GPU is overwhelmed by the pixel count, resulting in an average of only 50 FPS on Low settings. The GPU's shared memory architecture and low compute power make it unsuitable for 4K rendering.

Q: Is the Intel Core i7-14700F holding back the system?

A: No. The CPU is in the 91st percentile of all CPUs, with excellent multi-core and single-core scores. The data shows the GPU is the limiting component, as frame rates drop significantly with resolution, which is a GPU-bound behavior.

Q: What is the best resolution and settings for a playable experience?

A: The data suggests 1080p is the only resolution where the combo can consistently hit 60 FPS or above. At 1080p High, it averages 62 FPS. For higher refresh rates, 1080p Low achieves 118 FPS, but any setting above High at 1080p will drop below 60 FPS.

Q: How does this combo rank compared to other tested systems?

A: This combo ranks 2566th out of 2897 tested combinations for Assetto Corsa. This low ranking is due to the GPU's poor performance, not the CPU, which is in the top 10% of all processors.

Q: What does the "System Shared" memory mean for the GPU's performance?

A: The Arc B390 has no dedicated VRAM; it uses system memory. This makes its memory bandwidth "System Dependent," meaning performance can be affected by the system's RAM speed and capacity. This is a significant disadvantage compared to discrete GPUs with their own fast memory.

Q: Given the CPU's power, why does the system perform so poorly at 1440p?

A: The CPU is not the issue. At 1440p, the GPU is required to render more pixels than at 1080p, and the Arc B390 does not have the compute power to do so efficiently. The average FPS at 1440p High is only 44, which is a result of the GPU's 9th percentile ranking, not the CPU's capabilities.
