Rust

The Intel Core i5-10400F paired with the Intel Arc B370 delivers a constrained experience in Rust, with the data showing a fundamental imbalance between the CPU's solid multi-threaded foundation and the GPU's limited fill-rate capabilities. Benchmark results indicate that this combination, ranked 2710th out of 2953 tested combos, is heavily bottlenecked by the graphics subsystem across all tested resolutions. The measured FPS figures reveal a system that struggles to maintain playable frame rates at higher quality presets, though it performs adequately at lower settings and resolutions. The following analysis breaks down the specific performance characteristics of this pairing in Rust, interpreting the data to explain where the limitations lie and what users can expect from the measured configurations.

Resolution Scaling

The resolution scaling data for this combo shows a steep and consistent performance drop as pixel count increases, which is the classic signature of a GPU-bound scenario. At 1920x1080 with Low settings, the combo averages 69 FPS, but moving to 2560x1440 drops that figure to 48 FPS, a reduction of 21 FPS or roughly 30%. Scaling further to 3840x2160 brings the average down to 28 FPS, which is just 41% of the 1080p result. This pattern—where performance nearly halves from 1080p to 4K—indicates that the Intel Arc B370 is the limiting component, as the workload's demand on the GPU's shading units and memory bandwidth grows disproportionately with resolution.

The scaling behavior becomes more pronounced at higher quality presets. At Medium settings, the 1080p average of 46 FPS drops to 32 FPS at 1440p (a 30% decline) and then to 19 FPS at 4K (a 59% decline from 1440p). This non-linear degradation suggests that the GPU's 20 ROPs and 40 TMUs are insufficient for the increased pixel and texture workload at 4K. The Ultra preset tells a similar story: 30 FPS at 1080p, 20 FPS at 1440p, and just 12 FPS at 4K. The gap between 1440p and 4K at Ultra is 40%, which is less severe than at Medium, but the absolute numbers are so low that the experience is unplayable regardless.

Notably, the data shows that the CPU's performance headroom is not the issue. The i5-10400F has a boost clock of 4.30 GHz and scores 10283 in Cinebench R23 multicore, which is ample for Rust's typical single-threaded server logic. The fact that FPS scales so inversely with resolution—rather than remaining flat—confirms that the Arc B370's 6.144 TFLOPS FP32 throughput and System Shared memory are the choke points. At 1080p Low, the system achieves 69 FPS, but the GPU's 3 nm Panther Lake chip with a 2400 MHz boost clock simply cannot sustain that throughput as the pixel count rises.

Settings Recommendations

Based on the measured rows, the only configuration that approaches a smooth experience is 1920x1080 with Low settings, which yields an average of 69 FPS. This is the only setting combination in the entire dataset that breaks the 60 FPS threshold, making it the clear recommendation for any playable session. The Low preset at 1080p also shows the smallest variance in the data, with no min or max FPS recorded, suggesting a more stable frame delivery compared to Medium, which has a measured range of 39 to 53 FPS.

At 2560x1440, the Low preset produces 48 FPS average, which is playable but not ideal for fast-paced combat in Rust. The Medium preset at 1440p averages 32 FPS with a range of 27 to 37 FPS, introducing noticeable stutter. For users prioritizing visual fidelity over frame rate, the High preset at 1080p offers 39 FPS, which is a compromise but still feels sluggish. The Ultra preset should be avoided entirely, as it delivers 30 FPS at 1080p, 20 FPS at 1440p, and 12 FPS at 4K, all of which are well below the threshold for responsive gameplay.

The data indicates that the optimal strategy is to prioritize resolution reduction over quality reduction. Dropping from High to Low at 1080p yields a 77% FPS increase (from 39 to 69), while dropping from High to Low at 1440p yields a 78% increase (from 27 to 48). This suggests that the Arc B370's 1280 shading units are more sensitive to texture and shadow complexity than to raw pixel count, but the resolution scaling data contradicts this. The recommendation is to run 1080p Low for competitive play, or 1080p Medium for a visual upgrade that costs 23 FPS (from 69 to 46). Anything above Medium at 1080p, or any setting above Low at 1440p, results in average FPS below 40, which is insufficient for Rust's survival mechanics where reaction time matters.

GPU Role

The Intel Arc B370 is a mobile-oriented integrated GPU based on the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process. Its benchmark profile is extremely weak, scoring 1184 in 3DMark Steel Nomad DX12, which places it in the 5th percentile of all GPUs. The nearest rivals in the database are the ATI Mobility Radeon HD 5570 (scoring 1186, a 0.2% difference) and the ATI Radeon HD 5770 (scoring 1190, a 0.5% difference). This comparison underscores how underpowered this GPU is for modern gaming titles like Rust, which released in 2018 but has continued to receive graphical updates.

The GPU's specifications reveal why it struggles. It has 1280 shading units, 40 TMUs, and only 20 ROPs, with a base clock of 300 MHz and a boost clock of 2400 MHz. The memory is System Shared, meaning the bandwidth is System Dependent, which is a severe limitation for Rust's large open-world textures and draw distances. The pixel rate is 48.00 GPixel/s and the texture rate is 96.00 GTexel/s, but these theoretical figures are meaningless when the memory subsystem cannot feed the GPU fast enough. The 25 W TDP and IGP slot width confirm this is not designed for discrete gaming performance.

In Rust specifically, the GPU's role is to handle the rendering of terrain, building structures, and dynamic lighting. The measured FPS data shows that at 4K High, the combo averages 16 FPS, which is essentially a slideshow. The GPU's 10 ray tracing cores and DirectX 12 Ultimate support are irrelevant when the base rendering performance is this low. The fact that the Arc B370's nearest rivals are from 2010-era ATI cards (HD 5570 and HD 5770) indicates that this GPU is several generations behind modern gaming demands. For Rust, this means users must accept that the GPU will bottleneck the system at every resolution above 1080p Low.

How This Combo Ranks

The combo rank in Rust places this pairing at 2710 out of 2953 tested combinations, which puts it in the bottom 8% of all systems. This rank reflects the GPU's 5th percentile performance against all GPUs, which drags down the otherwise respectable 68th percentile ranking of the Intel Core i5-10400F against all CPUs. The CPU's average benchmark score of 14185 is within 0.5% of several rivals, including the Intel Xeon 6756E (14163, 0.2% higher) and the AMD EPYC 7552 (14115, 0.5% lower). This proximity indicates that the CPU is a mid-range performer, but its power is completely wasted when paired with the Arc B370.

The rank of 2710 out of 2953 means that 243 combos perform worse, but the vast majority of systems tested in the database outperform this pairing. The data shows that this combo is only suitable for the lowest graphical demands. The CPU's 6 cores and 12 threads with a 4.30 GHz boost clock would typically handle Rust's server-side calculations well, but the GPU cannot keep up with the frame rendering. The 3DMark results for the CPU, such as 4748 for 16 threads and 4735 for max threads, show consistent scaling, but the GPU's single benchmark score of 1184 is the anchor.

The combination's weaknesses are further highlighted by the fact that the GPU's nearest rivals are all ATI/AMD parts from over a decade ago. This means that even a modest discrete GPU from the past decade would likely outperform the Arc B370. The rank of 2710 suggests that users with this combo should expect to play Rust at the lowest settings and resolution, and even then, the 69 FPS at 1080p Low is the ceiling. The data does not support any expectation of higher performance without upgrading the GPU.

FAQ

Q: Can this combo run Rust at 4K with any playable frame rate?

A: No. The measured data shows 4K averages of 28 FPS on Low, 19 FPS on Medium, 16 FPS on High, and 12 FPS on Ultra. All of these are well below the 30 FPS minimum for acceptable playability, and the Low preset's 28 FPS is still too choppy for a survival game requiring precision.

Q: What is the best setting for 1080p gaming with this setup?

A: The 1920x1080 Low preset is the only configuration achieving an average above 60 FPS, at 69 FPS. The Medium preset drops to 46 FPS, which is playable but noticeably less smooth. High and Ultra at 1080p produce 39 FPS and 30 FPS respectively, making them poor choices.

Q: How does the Intel Arc B370 compare to its closest rivals in the database?

A: The Arc B370 scores 1184 in 3DMark Steel Nomad DX12. Its nearest rivals are the ATI Mobility Radeon HD 5570 (1186, 0.2% faster), the ATI Radeon HD 5770 (1190, 0.5% faster), and the AMD Radeon HD 7650M (1192, 0.7% faster). The AMD FirePro M2000 scores 1168, which is 1.4% slower.

Q: Is the CPU or GPU the limiting factor in Rust?

A: The GPU is definitively the limiting factor. The Intel Core i5-10400F has a boost clock of 4.30 GHz and scores 10283 in Cinebench R23 multicore, while the Arc B370 sits in the 5th percentile of all GPUs. The resolution scaling data confirms this, as FPS drops dramatically with higher pixel counts, indicating GPU saturation.

Q: What is the FPS range for 1440p Medium settings?

A: The measured data for 2560x1440 Medium shows an average of 32 FPS, with a minimum of 27 FPS and a maximum of 37 FPS. This range indicates significant frame time variance, which can cause stuttering during gameplay.

Q: Does the combo rank reflect the CPU or GPU performance?

A: The rank of 2710 out of 2953 is driven by the GPU's poor performance. The CPU alone ranks in the 68th percentile of all CPUs, but the GPU's 5th percentile ranking pulls the combined score down. The CPU's nearest rivals in average score are all within 0.6%, showing it is a balanced mid-range part, but the GPU cannot deliver acceptable frame rates.

Measured FPS Breakdown

The dataset provides 12 measured FPS points across four resolutions and four quality settings. At 1920x1080, the Low preset delivers an average of 69 FPS, which is the highest recorded value for this combo. The Medium preset at 1080p averages 46 FPS, with a measured range of 39 to 53 FPS. High settings at 1080p produce 39 FPS, and Ultra drops to 30 FPS. These numbers show a clear linear degradation as quality increases, with a 57% drop from Low to Ultra.

At 2560x1440, the Low preset averages 48 FPS, which is 21 FPS lower than the same preset at 1080p. Medium at 1440p averages 32 FPS with a range of 27 to 37 FPS. High averages 27 FPS, and Ultra averages 20 FPS. The scaling from 1080p to 1440p at each preset is consistent: Low drops 30%, Medium drops 30%, High drops 31%, and Ultra drops 33%. This uniformity indicates a consistent GPU bottleneck.

At 3840x2160, the Low preset averages 28 FPS, Medium averages 19 FPS (with a range of 16 to 22 FPS), High averages 16 FPS, and Ultra averages 12 FPS. The drop from 1440p to 4K is more severe: Low drops 42%, Medium drops 41%, High drops 41%, and Ultra drops 40%. This suggests that at 4K, the GPU's memory bandwidth constraints become even more critical, as the System Shared memory cannot cope with the increased data transfer demand.

The only configuration with recorded min and max values is the Medium preset across all resolutions. At 1080p Medium, the range is 39 to 53 FPS, a spread of 14 FPS. At 1440p Medium, the range is 27 to 37 FPS, a spread of 10 FPS. At 4K Medium, the range is 16 to 22 FPS, a spread of 6 FPS. The narrowing range at higher resolutions indicates that the GPU becomes more consistently saturated, reducing frame time variance but also capping the maximum FPS.

CPU Role

The Intel Core i5-10400F provides the computational foundation for this combo, with 6 cores and 12 threads based on the Comet Lake architecture. Its base clock of 2.90 GHz and boost clock of 4.30 GHz give it solid single-thread performance, as evidenced by a Passmark single-thread score of 2541 and a 3DMark single-thread score of 688. The CPU's multi-threaded capabilities are also robust, with a Cinebench R23 multicore score of 10283 and a Passmark multi-thread score of 12115. These figures place the CPU in the 68th percentile of all CPUs, indicating it is a competent mid-range processor.

In Rust, the CPU is responsible for server-side simulation, including entity updates, physics calculations, and network handling. The 3DMark 8-thread score of 3929 and 16-thread score of 4748 suggest that the CPU scales well with additional threads, which is beneficial for Rust's multi-threaded server ticks. However, the benchmark results also show that the CPU's performance is not the bottleneck in this combo. The fact that FPS scales so dramatically with resolution—from 69 FPS at 1080p Low to 28 FPS at 4K Low—proves that the GPU is limiting the frame rate, not the CPU.

The CPU's nearest rivals in average benchmark score are the Intel Xeon 6756E (14163, 0.2% lower), the Intel Core 7 160UL (14232, 0.3% higher), and the AMD EPYC 7552 (14115, 0.5% lower). These comparisons show that the i5-10400F is squarely in the middle of its performance class, but its 12 MB of shared L3 cache and DDR4 memory support (42.7 GB/s bandwidth) are adequate for Rust's requirements. The CPU's 14 nm process node and 65 W TDP are dated, but they do not negatively impact gaming performance in this title. The data suggests that if the GPU were upgraded, the CPU could likely support higher frame rates, as its multi-threaded scores are not being fully utilized at the current GPU-limited frame rates.
