Rust

The AMD Ryzen 7 9700X and Intel Arc B390 combination delivers a very specific, and largely GPU-limited, experience in Rust. The data indicates a system where a high-end 2024 processor is paired with an integrated graphics solution that is positioned near the bottom of the performance hierarchy. Benchmark results show this pairing ranks at 2601 out of 2953 tested combos, placing it in the bottom 12th percentile of all configurations tested in this game. This is a clear signal that while the CPU provides a robust foundation, the graphics subsystem is the primary bottleneck for gameplay.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 9700X is a powerful 8-core, 16-thread processor based on the Zen 5 architecture, built on TSMC's 4 nm process. It operates with a base clock of 3.80 GHz and can boost up to 5.50 GHz, making it a very capable part for modern gaming workloads. Its cache layout includes 80 KB of L1 per core, 1 MB of L2 per core, and a shared 32 MB of L3 cache. The processor supports DDR5 memory on a dual-channel bus, offering a memory bandwidth of 89.6 GB/s, and connects via PCIe Gen 5 with 24 lanes from the CPU itself.

In synthetic benchmarks, the 9700X shows strong multi-threaded performance. It scores 20,485 in Cinebench R23 multi-core and 17,906 in Geekbench multi-core. Its multi-threading scaling is also efficient; the gap between the 2-thread score of 2,525 and the max-thread score of 9,771 in 3DMark indicates good utilization of its 16 threads. The single-thread performance is also solid, with a Cinebench R23 single-core score of 2,211 and a Geekbench single-core score of 3,023. These numbers put the processor in the 86th percentile relative to all CPUs, with an average benchmark score of 37,943. Its nearest rivals are the Intel Core i9-14901E, AMD Ryzen AI 9 HX 370, Intel Core 5 211E, and AMD Ryzen AI Embedded P132, all of which are within a 0.4% margin of its average score. This means the CPU is performing exactly as expected for its class, offering no surprises in its compute capabilities.

However, Rust is a game that often stresses the CPU heavily, especially in complex scenes with many entities. The 9700X's strong multi-threading and high boost clocks should theoretically allow it to handle these loads well. Yet, the measured frame rates in this combo are low across the board. This suggests that while the CPU is capable, it is not the limiting factor in this configuration. The processor is effectively waiting on the GPU to produce frames, meaning its computational headroom is largely untapped in this specific pairing. The 65W TDP and unlocked multiplier indicate an efficient and overclockable part, but those features do not translate to higher FPS here because the graphics pipeline is saturated first.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, built on Intel's 3 nm process. It has a base clock of 300 MHz and a boost clock of 2500 MHz. Critically for gaming, it uses "System Shared" memory, meaning it has no dedicated VRAM; instead, it draws from the system's main DDR5 memory. The memory bus width and bandwidth are also "System Shared" and "System Dependent," respectively, which means its performance is heavily reliant on the speed and configuration of the system RAM.

This GPU is a very modest performer. It has 1,536 shading units, 48 TMUs, and 24 ROPs, along with 12 ray tracing cores. Its raw compute is rated at 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16 (2:1). In the 3DMark Steel Nomad DX12 test, it scores 1,482 points, placing it in the 9th percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce GT 520MX (1,463 points), NVIDIA GeForce 800M (1,460 points), NVIDIA GeForce GT 625 OEM (1,446 points), and NVIDIA GeForce GT 710 (1,443 points). The Arc B390 is only 1.3% to 2.7% faster than these legacy entry-level parts, which contextualizes its performance level as being akin to a very old, low-end graphics solution.

In Rust, the GPU's lack of dedicated VRAM and low compute throughput is the primary constraint. The game requires substantial graphics memory and processing power, especially for textures and draw calls. The measured FPS in this combo is consistently low, confirming that the Arc B390 is the bottleneck. The system's performance is defined by this GPU's limits, not the CPU's. The 80W TDP and "IGP" slot width confirm this is an integrated solution, not a discrete card, which explains its performance tier. The fact that it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 is irrelevant when the hardware cannot push enough pixels to make use of those APIs at playable frame rates.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear and expected pattern of performance degradation as resolution increases, but the magnitude of the drop is revealing. At 1920x1080 (1080p) with Low settings, the combo achieves 76 FPS. Moving to 2560x1440 (1440p) with Low settings, the average drops to 53 FPS, a significant 30% decrease. At 3840x2160 (4K) with Low settings, the average falls further to 31 FPS, which is a 59% drop from the 1080p result.

This scaling pattern is typical of a GPU-bound scenario. When the resolution increases, the number of pixels the GPU must render rises exponentially. The Arc B390's limited fill rate and memory bandwidth are quickly overwhelmed. The 1080p Low result of 76 FPS is the only playable number in the entire dataset. The 1440p Low result of 53 FPS is borderline, but the 4K Low result of 31 FPS is not smooth.

For the Medium settings, the drop from 1080p (51 FPS) to 1440p (35 FPS) is a 31% reduction, and further to 4K (21 FPS) is a 59% reduction. The High settings show a similar trend: 43 FPS at 1080p, 30 FPS at 1440p (a 30% drop), and 18 FPS at 4K (a 58% drop). This consistent ~30% drop from 1080p to 1440p and ~58-59% drop from 1080p to 4K across all settings confirms that the GPU is the limiting component. If the CPU were the bottleneck, we would expect frame rates to be more stable across resolutions, as the CPU workload does not increase as dramatically with pixel count. The data clearly indicates that the integrated GPU is running out of steam at higher resolutions, regardless of the graphics preset.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 7 9700X and Intel Arc B390 ranks 2601 out of 2953 tested combos in Rust. This places it in the bottom 12% of all configurations, which is a very poor result. The ranking reflects the overall gaming experience, which is dominated by the GPU's performance. The CPU's high percentile (86th) is completely negated by the GPU's low percentile (9th), resulting in a combined system that is far below average for gaming.

This ranking is a direct consequence of the GPU bottleneck. The 9700X is a top-tier processor, but it is paired with a graphics solution that performs at the level of a decade-old entry-level discrete card. The data suggests that this combo would be better suited for productivity tasks or light, non-demanding workloads rather than modern gaming. The benchmark results indicate that users would see a massive improvement in frame rates by simply swapping the Arc B390 for a more capable discrete GPU, as the CPU has ample headroom to support a much faster graphics card. The rank of 2601 out of 2953 is a stark warning that this configuration will struggle to provide a satisfying experience in Rust.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive look at this combo's performance. At 1920x1080, the results are as follows: Low settings yield an average of 76 FPS, Medium yields 51 FPS with a minimum of 44 and a maximum of 59, High yields 43 FPS, and Ultra yields 33 FPS. This is the only resolution where any setting achieves a playable frame rate, and even then, only the Low preset is consistently smooth.

At 2560x1440, the performance drops significantly. Low settings average 53 FPS, Medium averages 35 FPS (with a min of 30 and max of 41), High averages 30 FPS, and Ultra averages 23 FPS. The drop from 1080p is substantial across all settings, reinforcing the GPU-bound nature of the system. The 1440p results are mostly unplayable, with only the Low preset approaching a playable threshold.

At 3840x2160, the performance is critically low. Low settings average 31 FPS, Medium averages 21 FPS (with a min of 18 and a max of 24), High averages 18 FPS, and Ultra averages 13 FPS. At 4K, no setting is remotely playable, and the frame rates are below the threshold for a consistent gaming experience. The data shows that the Arc B390 is simply not capable of handling the pixel workload at this resolution.

Settings Recommendations — which preset gives the best experience per the measured rows

Given the measured data, the only viable path to a playable experience is to use the Low preset at 1920x1080, which yields an average of 76 FPS. This is the highest frame rate recorded in any configuration and is the only one that comfortably exceeds the 60 FPS threshold for smooth gameplay. The Medium preset at 1080p, which averages 51 FPS, is the next best option, but it may feel less consistent due to the minimum FPS of 44.

For users who prioritize visual quality over frame rate, the High preset at 1080p (43 FPS) is a trade-off, but it is still playable for some. The Ultra preset at 1080p (33 FPS) and all settings at 1440p and 4K are not recommended for any serious gameplay, as the frame rates dip too low to be enjoyable. The data suggests that resolution is a more critical factor than settings for this combo. Dropping from 1080p to 1440p at the same settings incurs a ~30% performance penalty, which is a larger hit than what can be recovered by adjusting the graphics preset at the same resolution.

In practical terms, the best experience is achieved by locking the resolution to 1920x1080 and selecting the Low preset. This maximizes FPS and provides the most headroom for the game's engine. If the visual quality is too low, the Medium preset is a reasonable compromise, but users should expect some frame dips. There is no benefit to running at higher resolutions, as the GPU cannot handle the extra pixel load. The recommendation from the measured rows is clear: prioritize resolution (1080p) over settings, and use the Low preset for the best performance.
