Rust

The AMD Ryzen 7 5700G paired with the Intel Arc B370 produces a limited performance profile in Rust, with measured frame rates that place this combination near the bottom of the tested pool. The data shows a system that can handle the game at lower resolutions and settings, but one that struggles significantly as graphical demands increase. This analysis breaks down the measured FPS across resolutions and settings, examines the CPU and GPU contributions, and provides recommendations based solely on the benchmark results.

Resolution Scaling

The measured FPS data reveals a steep performance decline as resolution increases, indicating that the Intel Arc B370 is the primary limiting component in this configuration. At 1080p with Low settings, the combo achieves an average of 69 FPS. Moving to 1440p Low drops that to 48 FPS, a reduction of 21 FPS (approximately 30%). At 4K Low, the average falls to 28 FPS, which is less than half of the 1080p Low result. This pattern is consistent across all settings presets.

For High settings, the scaling is equally pronounced. The 1080p High average of 39 FPS drops to 27 FPS at 1440p High, and then to 16 FPS at 4K High. The delta between 1080p and 4K High is 23 FPS, representing a 59% loss. Medium settings show a similar trajectory: 46 FPS at 1080p, 32 FPS at 1440p, and 19 FPS at 4K. Ultra settings produce the lowest overall numbers, with 30 FPS at 1080p, 20 FPS at 1440p, and just 12 FPS at 4K.

These results indicate that the GPU’s rendering capability scales poorly with pixel count. The Arc B370’s 6.144 TFLOPS FP32 throughput and 20 ROPs are simply insufficient for the demands of 4K rendering in Rust. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are modest figures that align with the observed frame rates. The fact that even Low settings at 4K only achieve 28 FPS suggests that the GPU is heavily saturated at that resolution.

The scaling pattern also shows that the CPU is not the bottleneck at higher resolutions. Since frame rates drop consistently with resolution, the workload is shifting to the GPU. The Ryzen 7 5700G’s eight cores and sixteen threads provide ample processing headroom, as evidenced by its benchmark scores, but the GPU cannot keep pace. At 1080p Low, the 69 FPS result may still be CPU-limited in certain scenes, but the overall trend points to GPU limitation dominating the experience.

How This Combo Ranks

The combo rank in Rust places this configuration at 2710 out of 2953 tested combinations. This means it sits in the bottom 8% of all tested combos, which is consistent with the low measured frame rates. The GPU’s percentile ranking of 5 against all GPUs further underscores its position at the lower end of the performance spectrum. In contrast, the CPU’s percentile ranking of 79 against all CPUs shows that the processor is not the weak link in this pairing.

Looking at the GPU’s nearest rivals, the Arc B370’s average benchmark score of 1184 is nearly identical to that of the ATI Mobility Radeon HD 5570 (1186, deltaPct -0.2) and the ATI Radeon HD 5770 (1190, deltaPct -0.5). This places the Arc B370 in the company of older discrete GPUs from over a decade ago, which explains why Rust performance is so constrained. The AMD Radeon HD 7650M scores 1192 (deltaPct -0.7) and the AMD FirePro M2000 scores 1168 (deltaPct 1.4), all within a narrow band of each other.

For the CPU, the Ryzen 7 5700G’s average benchmark score of 27051 is closely matched by its nearest rivals. The Intel Core i9-9900K scores 27097 (deltaPct -0.2), the Intel Core i5-14400T scores 27166 (deltaPct -0.4), the AMD Ryzen AI 7 445 scores 26936 (deltaPct 0.4), and the Intel Core i7-1370P scores 26900 (deltaPct 0.6). These deltas are all within 0.6%, meaning the CPU performance is essentially comparable to those parts. However, the GPU’s low standing drags the entire combo down to the 2710th position.

The rank of 2710 out of 2953 indicates that the vast majority of tested combinations deliver higher frame rates in Rust. This is not a surprise given the GPU’s 5th percentile ranking. The data suggests that users seeking playable Rust performance should look toward combinations with more powerful GPUs, as the CPU is capable of supporting higher frame rates if paired with a stronger graphics solution.

CPU Role

The AMD Ryzen 7 5700G is a Zen 3 architecture processor built on a 7nm process, featuring eight cores and sixteen threads. Its base clock is 3.80 GHz with a boost clock of 4.60 GHz. The 16 MB L3 cache and 512 KB L2 per core provide adequate cache hierarchy for gaming workloads. The CPU’s benchmark results show strong multi-threaded performance: Cinebench R23 multicore scores 12830.5, while the single-core score is 1494. Geekbench multicore reaches 9950 with a single-core score of 1894. Passmark multithread scores 24419, and the 3DMark 16-thread test yields 6629.

In Rust, the CPU’s role is to handle game logic, physics, and entity updates. The measured FPS at 1080p Low (69 FPS) suggests that the CPU can push beyond this level if the GPU allowed it. The fact that 1080p Low is the only preset reaching near 70 FPS indicates that the GPU is the bottleneck at higher settings. The CPU’s single-thread performance, as shown by the 3DMark single-thread score of 899 and Passmark single-thread score of 3283, is adequate for Rust’s typical threading model, which often relies on a few heavily loaded threads.

The CPU’s nearest rivals all have similar average benchmark scores, with deltas under 1%. This means the 5700G’s processing power is on par with parts like the Intel Core i9-9900K. Yet, in this combo, the CPU’s potential is largely untapped due to the GPU constraint. At 4K resolutions, the CPU is almost certainly idle waiting on the GPU, as frame rates drop to 12-28 FPS regardless of settings.

The memory bandwidth of 51.2 GB/s for DDR4 dual-channel is another factor. Rust can be memory-sensitive, but with the GPU as the primary limiter, memory performance is not the constraining factor in these measurements. The CPU’s 65W TDP and unlocked multiplier suggest it could be overclocked to improve performance, but the benchmark data does not include overclocked results, so any gains would be speculative.

Overall, the CPU is a capable mid-range part that performs well above the GPU in this pairing. The data shows that upgrading the GPU would yield significant FPS improvements, while the CPU would remain a solid foundation for 1080p and 1440p gaming.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings presets (Low, Medium, High, Ultra). At 1080p, the results are as follows: Low averages 69 FPS, Medium averages 46 FPS with minimum 39 and maximum 53, High averages 39 FPS, and Ultra averages 30 FPS. The spread from Low to Ultra is 39 FPS, showing that settings have a substantial impact at this resolution.

At 1440p, the averages drop: Low 48 FPS, Medium 32 FPS (min 27, max 37), High 27 FPS, and Ultra 20 FPS. The spread from Low to Ultra is 28 FPS, indicating that settings still matter but the overall performance ceiling is lower. The Medium preset’s minimum of 27 FPS is notable, as it shows the frame rate can dip below the average in demanding scenes.

At 4K, the results are severely limited: Low 28 FPS, Medium 19 FPS (min 16, max 22), High 16 FPS, and Ultra 12 FPS. The spread from Low to Ultra is 16 FPS, and even the best case (Low) falls below 30 FPS. The Medium preset’s minimum of 16 FPS suggests that playability is questionable even at lower settings.

The data shows that only 1080p Low achieves a frame rate above 60 FPS. 1080p Medium and 1440p Low are the only other presets that break 45 FPS. Everything else falls below 40 FPS, with 4K presets all under 30 FPS. For a smooth gaming experience, typically 60 FPS or higher, only 1080p Low comes close, and it still falls short by 9 FPS.

The lack of min/max FPS data for most presets limits the analysis, but the Medium preset at each resolution provides some insight. At 1080p Medium, the minimum is 39 FPS and maximum is 53 FPS, showing a 14 FPS variance. At 1440p Medium, the range is 27 to 37 FPS (10 FPS variance). At 4K Medium, the range is 16 to 22 FPS (6 FPS variance). This suggests that frame pacing becomes more consistent at lower resolutions, while higher resolutions exhibit smaller absolute variances due to lower overall FPS.

GPU Role

The Intel Arc B370 is an integrated GPU solution based on the Xe3-LPG architecture, built on a 3nm process. It has 1280 shading units, 40 TMUs, and 20 ROPs. The base clock is 300 MHz with a boost clock of 2400 MHz. Memory is system shared, meaning it relies on the CPU’s DDR4 memory, with bandwidth described as system dependent. The GPU’s FP32 performance is 6.144 TFLOPS, with FP16 at 12.29 TFLOPS (2:1). It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The GPU’s benchmark score of 1184 in 3DMark Steel Nomad DX12 places it at the 5th percentile of all GPUs. Its nearest rivals are all older discrete GPUs from the ATI/AMD Radeon HD series, with scores within 1.4% of the Arc B370. This indicates that the Arc B370’s performance is roughly equivalent to a low-end GPU from the early 2010s, which is insufficient for modern gaming at high resolutions.

In Rust, the GPU’s limitations are evident across all measured settings. The pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are low figures that constrain fill-rate-dependent scenes. The 20 ROPs limit the number of pixels that can be written per clock, which is particularly problematic at 4K where the pixel count is over eight million. The 6.144 TFLOPS FP32 throughput is modest, and while Rust is not a compute-heavy game, the shader work required at higher settings overwhelms the GPU.

The system shared memory means the GPU has no dedicated VRAM, which can cause additional latency and bandwidth contention with the CPU. The 51.2 GB/s memory bandwidth of the CPU is shared between both components, and the GPU’s needs may exceed what is available, especially at higher resolutions. This is consistent with the severe FPS drops seen at 4K, where memory bandwidth becomes a critical factor.

The GPU’s TDP of 25W is extremely low, reflecting its integrated nature. This means it cannot sustain high clock speeds under sustained load, which further limits performance. The boost clock of 2400 MHz is only achievable under ideal conditions, and thermal or power constraints may reduce it during extended gaming sessions.

Given the GPU’s 5th percentile ranking and its performance equivalence to the ATI Radeon HD 5770, it is clear that this GPU is not designed for demanding titles like Rust at high settings. The measured FPS data confirms this, with even 1080p Low falling below 70 FPS, and all other presets failing to reach 50 FPS.

Settings Recommendations

Based on the measured FPS data, the only setting preset that provides a playable experience is 1920x1080 with Low settings, which averages 69 FPS. This is the sole configuration that approaches the 60 FPS threshold commonly desired for smooth gameplay. For users who prioritize frame rate, this is the recommended choice.

If 60 FPS is not a strict requirement, 1440p Low (48 FPS) and 1080p Medium (46 FPS) offer a balance between visual quality and performance. Both presets stay above 45 FPS, which can be acceptable for less competitive play. The 1080p Medium preset has a minimum of 39 FPS, ensuring that most scenes remain above 30 FPS.

For users who prefer higher visual fidelity, 1080p High (39 FPS) is a viable option, though it falls below 40 FPS. 1440p Medium (32 FPS) and 1080p Ultra (30 FPS) are marginal, with averages at or below 32 FPS. These presets may result in noticeable stuttering, especially in busy scenes.

The 4K presets are not recommended under any settings. The best 4K result is 28 FPS at Low, which is below the playability threshold. 4K Medium averages 19 FPS, 4K High 16 FPS, and 4K Ultra 12 FPS. These numbers indicate that the GPU cannot handle Rust at this resolution, and users should avoid 4K entirely with this combo.

In summary, the optimal experience is 1080p Low for maximum frame rate, with 1440p Low or 1080p Medium as alternatives for slightly better visuals while maintaining playable performance. Higher settings at any resolution will result in average FPS below 40, which is insufficient for a smooth experience in Rust. The data clearly shows that this system is best suited for low-resolution, low-settings gaming, and any attempt to push higher will result in significant performance degradation.
