Rust

The AMD Ryzen 7 5800X and Intel Arc B370 combination delivers a profoundly GPU-limited experience in Rust, with performance metrics that place it near the bottom of the database’s tested configurations. The measured frame rates indicate that this pairing struggles to maintain playable fluidity even at 1080p, a bottleneck that becomes increasingly severe as resolution climbs.

Resolution Scaling

The data reveals a stark and linear penalty as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 39 FPS at 1080p to 27 FPS at 1440p, a 12 FPS reduction. Moving to 4K High yields just 16 FPS, which is less than half of the 1080p result. This pattern strongly suggests that the Intel Arc B370’s rendering capabilities are the primary constraint, as the frame rate collapses in near-perfect proportion to the pixel count increase.

The Low preset tells an even more revealing story. At 1080p Low, the system achieves 69 FPS, which is a respectable number for this hardware tier. However, at 1440p Low, the average drops to 48 FPS, and at 4K Low, it plummets to 28 FPS. The scaling from 1440p to 4K represents a 41.7% reduction in frame rate, which is remarkably close to the pixel density increase. This near-linear scaling is the classic signature of a GPU that is completely saturated at every resolution, with no headroom left for the CPU to compensate.

The Medium preset shows similar behavior, with averages of 46 FPS at 1080p, 32 FPS at 1440p, and 19 FPS at 4K. The Ultra preset, which is the most demanding, yields 30 FPS at 1080p, 20 FPS at 1440p, and 12 FPS at 4K. Across all presets, the 4K results are uniformly below 30 FPS, which indicates that this combination is not viable for 4K gaming in Rust under any settings configuration. The data implies that the Arc B370’s memory bandwidth, which is marked as "System Shared" and "System Dependent", becomes a critical weakness at high resolutions, where the demand for texture and geometry data outpaces what the shared memory subsystem can deliver.

GPU Role

The Intel Arc B370 is an integrated graphics processor based on the Xe3-LPG architecture, manufactured on Intel’s 3 nm process. Its specifications include 1280 shading units, 40 texture mapping units, and 20 raster output units, along with 10 ray tracing cores. The clock speeds are listed with a base of 300 MHz and a boost of 2400 MHz, which suggests significant dynamic range, but the measured results indicate that this does not translate into sustained gaming performance.

The GPU’s memory configuration is entirely "System Shared", with no dedicated VRAM. This means the graphics processor must compete with the CPU for access to the same DDR4 memory pool, which is a severe handicap in a game like Rust that is known for its large, persistent world and complex asset streaming. The benchmark data confirms this limitation: the GPU’s 3DMark Steel Nomad DX12 score is 1184, placing it in the 5th percentile of all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570 and the ATI Radeon HD 5770, both of which are over a decade old, underscoring the Arc B370’s position at the very bottom of the performance hierarchy.

The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are theoretically capable of handling 1080p output, but the shared memory bottleneck appears to throttle actual throughput. The FP32 performance of 6.144 TFLOPS is also modest, and the data suggests that this theoretical compute power is not being effectively utilized in Rust, likely due to driver overhead or memory latency issues. The measured FPS values at 1080p Low (69 FPS) are the only instance where the system approaches a smooth experience, and even that is marginal. At any higher preset or resolution, the GPU’s lack of dedicated VRAM and low memory bandwidth become insurmountable obstacles.

How This Combo Ranks

The combo rank for this specific pairing in Rust is 2710 out of 2953 tested combinations, placing it in the 8th percentile of all systems evaluated. This is an exceptionally poor ranking, and it aligns with the GPU’s 5th percentile standing among all graphics cards. The CPU, by contrast, is a much stronger component, with a percentile ranking of 81 among all processors.

The disparity between the CPU’s capability and the GPU’s deficiency is stark. The Ryzen 7 5800X has an average benchmark score of 29123, which is nearly identical to its nearest rivals: the Intel Core Ultra 5 135H (29093), the Intel Xeon Phi 7210 (29245), and the Intel Core i5-13500HX (29270). The delta percentages are all within 0.6% of zero, indicating that the CPU is performing exactly as expected for its class. However, the GPU’s average benchmark score of 1184 is within 1.4% of its nearest rivals, which are all legacy parts from the early 2010s.

This combination represents a massive mismatch. The CPU is a high-end desktop part from 2020, while the GPU is an integrated solution designed for portable devices, released in early 2026. In the context of the database’s 2953 tested combos, this pairing ranks 2710th, meaning it outperforms only 243 other configurations. The data suggests that any system builder pairing this CPU with even a modest discrete GPU would see dramatically better results, as the current bottleneck is entirely on the graphics side.

Measured FPS Breakdown

At 1920x1080, the system delivers its best results, though they remain underwhelming. The Low preset achieves an average of 69 FPS, which is the only setting that crosses the 60 FPS threshold. The Medium preset follows at 46 FPS, with a minimum of 39 FPS and a maximum of 53 FPS, indicating noticeable frame drops during intense scenes. High preset yields 39 FPS, and Ultra drops to 30 FPS. None of these values are smooth for a competitive survival game, but Low is at least playable.

Moving to 2560x1440, the performance falls off sharply. Low preset averages 48 FPS, Medium averages 32 FPS (minimum 27, maximum 37), High averages 27 FPS, and Ultra averages 20 FPS. The gap between Low and Ultra at this resolution is 28 FPS, which is a 58% reduction in performance, showing that the GPU’s limited resources are quickly exhausted as quality settings increase.

At 3840x2160, the results are uniformly poor. Low preset averages 28 FPS, Medium averages 19 FPS (minimum 16, maximum 22), High averages 16 FPS, and Ultra averages 12 FPS. The Ultra preset at 4K is effectively unplayable, and even Low is below the threshold for smooth motion. The data shows a consistent pattern: each step up in resolution or preset costs roughly 5-10 FPS, and the system never recovers from the initial deficit at 1080p.

CPU Role

The AMD Ryzen 7 5800X is a Zen 3 architecture processor with 8 cores and 16 threads, running at a base clock of 3.80 GHz and a boost clock of 4.70 GHz. It is manufactured on a 7 nm process with 4,150 million transistors and features 32 MB of L3 cache. Its memory support is DDR4 with a dual-channel bus and 51.2 GB/s of bandwidth, and it uses the AMD Socket AM4 interface.

In terms of raw processing power, the CPU is well-equipped for gaming. Its Cinebench R23 multicore score is 15476 and single-core score is 1574.5, while its Geekbench multicore score is 11036 and single-core score is 2032. The PassMark multithread score is 27732, and the single-thread score is 3445. These numbers place the 5800X in the 81st percentile of all CPUs, which is a strong showing for a desktop part from late 2020.

However, in the context of this Rust benchmark, the CPU’s capabilities are largely irrelevant. The measured FPS values are so low that the CPU is never the limiting factor; even at 1080p Low, where the GPU is producing 69 FPS, the 5800X is likely operating well below its potential. The 3DMark 16-thread score of 7586 and the 8-thread score of 6035 indicate that the CPU can handle heavy multi-threaded workloads, but Rust’s frame rate is constrained by the GPU’s output. The data implies that if the Arc B370 were replaced with a more capable graphics card, the 5800X would have ample headroom to push much higher frame rates, as its nearest rivals with similar scores are used in systems that achieve far better gaming results.

Settings Recommendations

Given the measured data, the only viable path to a playable experience is to use the 1920x1080 resolution with the Low preset, which produces an average of 69 FPS. This is the sole configuration that breaks the 60 FPS barrier, and it is the only setting that provides a smooth enough frame rate for a fast-paced survival game where reaction time matters.

For users who prioritize visual quality over frame rate, the 1080p Medium preset at 46 FPS is a compromise, though the minimum of 39 FPS indicates that stuttering may occur during heavy load. The High preset at 1080p (39 FPS) and Ultra preset at 1080p (30 FPS) are both below the threshold for comfortable play, but they offer progressively better visuals. At 1440p, the Low preset (48 FPS) is the only option that approaches playability, while all 4K presets are firmly in the field of slideshow territory.

The data suggests that this system is fundamentally unsuited for Rust at higher resolutions or quality settings. The best experience, per the measured rows, is unambiguously 1080p Low at 69 FPS. Any attempt to increase quality or resolution results in a disproportionate loss of frame rate, confirming that the Intel Arc B370’s limitations cannot be overcome through settings adjustments. Users seeking better performance would need to upgrade the GPU, as the CPU is clearly not the bottleneck in this configuration.
