Rust

The AMD Ryzen 9 7900X and Intel Arc B370 pairing in Rust produces a profoundly GPU-limited experience, as evidenced by the measured frame rates across all tested settings and resolutions. This combination ranks 2710th out of 2953 tested combos in the database, placing it in the bottom 8 percent of all configurations for this title. The data shows a system where a high-end 12-core processor is paired with an integrated-class graphics solution, resulting in playable frame rates only at the lowest settings and resolutions.

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

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 architecture, codenamed Raphael. It operates on the AMD Socket AM5 platform and is built on TSMC's 5 nm process node. The CPU's base clock is 4.70 GHz with a boost clock of 5.60 GHz, and it carries a TDP of 170 W. The processor includes 64 MB of shared L3 cache, with 1 MB of L2 cache per core and 64 KB of L1 cache per core, totaling 13,140 million transistors across a 2x 71 mm² die size.

In terms of raw computational throughput, the 7900X delivers strong results. Its Cinebench R23 multicore score is 29300, with a single-core score of 2016.5. The 3DMark suite shows a max-thread score of 12536, while the 8-thread test yields 7798. The Geekbench multicore result is 19267, and the single-core score is 2617. PassMark tests reinforce this profile: multithread score of 51406, single-thread score of 4238, integer math at 169273, and floating-point math at 103952. The processor's percentile versus all CPUs is 91, indicating it outperforms the vast majority of processors in the database.

The nearest rivals to the 7900X in average benchmark score include the AMD EPYC 7313P (0.2% ahead), the Intel Xeon Phi 7290 (0.3% behind), the Intel Xeon 634 (0.6% ahead), and the Intel Core i7-14700F (0.6% behind). These deltas are minimal, showing the 7900X sits in a tightly contested performance band for general CPU benchmarks.

For Rust specifically, the CPU's role is largely theoretical because the measured frame rates are so low that the processor is never the limiting factor. At 1080p Low, the system produces 69 FPS average, which is the highest result in the entire dataset. Given the 7900X's capabilities, this frame rate is almost certainly constrained by the GPU rather than the CPU. The 12 cores and 24 threads provide ample headroom for Rust's simulation and entity processing, but the data shows the graphics pipeline bottlenecks the system well before CPU saturation occurs. The 64 MB L3 cache helps with game-world data access, but this advantage is invisible in the measured results because the GPU cannot keep up with even moderate CPU-driven frame generation.

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

The Intel Arc B370 is an integrated graphics processor based on the Xe3-LPG architecture, part of the Panther Lake chip generation. It is fabricated on Intel's 3 nm process node and features a base clock of 300 MHz with a boost clock of 2400 MHz. The GPU has 1280 shading units, 40 texture mapping units, and 20 raster operation units, along with 10 ray tracing cores. Its pixel rate is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s, with FP32 performance at 6.144 TFLOPS and FP16 at 12.29 TFLOPS (2:1).

Critically, the Arc B370 uses system shared memory for both its VRAM and memory bus, with bandwidth listed as system dependent. This means the GPU's memory performance is tied entirely to the host system's DDR5 memory configuration, which for the 7900X is dual-channel with 83.2 GB/s bandwidth. The integrated nature of this GPU (slot width is IGP, power connectors are None, TDP is 25 W) means it is designed for basic graphical output rather than gaming performance.

The GPU's benchmark results reflect this positioning. Its only 3DMark Steel Nomad DX12 score is 1184, placing it at the 5th percentile of all GPUs. The nearest rivals are the ATI Mobility Radeon HD 5570 (0.2% ahead), the ATI Radeon HD 5770 (0.5% ahead), the AMD Radeon HD 7650M (0.7% ahead), and the AMD FirePro M2000 (1.4% behind). These are all legacy or low-end parts, confirming the Arc B370's performance class.

In Rust, the GPU's limitations are stark. At 1080p Low, the system achieves 69 FPS average, but this drops to 39 FPS at High settings. The scaling from Low to Ultra at 1080p shows a decline from 69 to 30 FPS, a 57% reduction. The GPU's 6.144 TFLOPS of FP32 compute is simply insufficient for Rust's rendering demands at higher settings, and the shared memory bandwidth creates additional bottlenecks. The 2400 MHz boost clock helps at lower resolutions, but the fundamental architecture limits what the system can deliver.

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

The resolution scaling data reveals a classic GPU-bound scenario. Moving from 1080p to 1440p to 4K at each settings level produces substantial frame rate drops that correlate with pixel count increases. At Low settings, the system goes from 69 FPS at 1080p to 48 FPS at 1440p and 28 FPS at 4K. This represents a 30% drop from 1080p to 1440p and a 42% further drop from 1440p to 4K. The total decline from 1080p to 4K at Low is 59%.

At High settings, the progression is 39 FPS at 1080p, 27 FPS at 1440p, and 16 FPS at 4K. The percentage drops are 31% and 41% respectively, showing a similar pattern to Low settings. Medium settings show 46 FPS at 1080p, 32 FPS at 1440p, and 19 FPS at 4K, with drops of 30% and 41%. Ultra settings follow the same trend: 30 FPS at 1080p, 20 FPS at 1440p, and 12 FPS at 4K, representing 33% and 40% declines.

The consistency of these percentage drops across all settings levels is telling. If the CPU were the bottleneck, we would expect resolution to have minimal impact on frame rates, as the CPU workload in Rust (entity updates, network handling, world simulation) does not scale with pixel count. Instead, the near-uniform 30-33% drop from 1080p to 1440p and 40-42% drop from 1440p to 4K indicates that the GPU's pixel throughput is the primary constraint. The Arc B370's 48.00 GPixel/s pixel rate and shared memory bandwidth are overwhelmed as resolution increases, and the CPU's substantial headroom remains unused.

The data also shows that the minimum FPS values (where recorded) scale proportionally. At Medium settings, the minimum FPS drops from 39 at 1080p to 27 at 1440p and 16 at 4K, while maximum FPS drops from 53 to 37 to 22. This proportional scaling reinforces the GPU-bound analysis, as CPU-bound scenarios typically show more erratic frame time variations rather than smooth, predictable declines.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 9 7900X and Intel Arc B370 combination ranks 2710 out of 2953 tested combos in Rust. This places the combo in the bottom 8.2% of all configurations tested for this game. The rank of 2710 means there are 2709 combos that perform better, and only 243 combos that perform worse. Given the GPU's 5th percentile ranking among all GPUs, this result is expected — the CPU is in the 91st percentile, but the overall combo performance is dragged down by the integrated graphics solution.

The disparity between the CPU's high percentile (91) and the combo's low rank (2710/2953) highlights the extreme imbalance in this pairing. The 7900X is a top-tier processor that could drive much higher frame rates in Rust if paired with a discrete GPU, but the Arc B370's integrated nature caps the system's performance. The combo rank is more reflective of the GPU's capabilities than the CPU's, as the measured FPS values across all resolutions and settings are consistently low.

In the context of the database, this combo sits near the bottom of the distribution. The rank of 2710 means the system is in the 92nd percentile of worst-performing combos, which is a more useful way to interpret the data given the negative framing of rank. The 243 combos that perform worse likely feature even more limited integrated graphics or older hardware. The nearest rivals to the GPU (ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, AMD FirePro M2000) are all from an older era, suggesting the Arc B370 is competitive with roughly 15-year-old discrete graphics solutions.

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

At 1920x1080, the system produces the highest frame rates in the dataset. Low settings yield an average of 69 FPS, which is the only result above 60 FPS across all tested configurations. Medium settings drop to 46 FPS average, with a minimum of 39 FPS and a maximum of 53 FPS. High settings produce 39 FPS average, and Ultra settings yield 30 FPS average. The spread from Low to Ultra at 1080p is 39 FPS, showing a significant performance cost for higher visual quality.

At 2560x1440, the frame rates decline noticeably. Low settings average 48 FPS, Medium settings average 32 FPS with a minimum of 27 FPS and maximum of 37 FPS, High settings average 27 FPS, and Ultra settings average 20 FPS. The gap between Low and Ultra at 1440p is 28 FPS, which is a smaller absolute difference than at 1080p but a similar relative difference (58% reduction from Low to Ultra at both resolutions).

At 3840x2160, the system struggles to maintain playable frame rates. Low settings average 28 FPS, Medium settings average 19 FPS with a minimum of 16 FPS and maximum of 22 FPS, High settings average 16 FPS, and Ultra settings average 12 FPS. The Low to Ultra gap at 4K is 16 FPS, and even the best case (Low) falls below 30 FPS, which is generally considered the minimum for acceptable gameplay smoothness.

The data shows that Medium settings at 1080p (46 FPS average) is the only configuration that provides a playable experience above 45 FPS. Low settings at 1080p (69 FPS) is the only configuration that exceeds 60 FPS. All other configurations fall below 50 FPS, with the majority of 1440p and 4K results falling below 35 FPS. The minimum FPS values at Medium settings (39 at 1080p, 27 at 1440p, 16 at 4K) show that even the average frame rates hide significant dips that would be noticeable during gameplay.

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

Based on the measured FPS data, the optimal settings for this combo depend on the user's resolution and performance priorities. At 1080p, Low settings provide the best experience with 69 FPS average, which is the only configuration that fully utilizes a 60 Hz display. Medium settings at 1080p offer 46 FPS average, which is playable but requires either a 45 Hz or variable refresh rate display to avoid tearing. High and Ultra settings at 1080p (39 FPS and 30 FPS respectively) are marginal for gameplay, with Ultra dipping below the 30 FPS threshold that most players consider the minimum for acceptable smoothness.

At 1440p, Low settings (48 FPS) is the only configuration that approaches playable frame rates. Medium settings (32 FPS) and High settings (27 FPS) are borderline, while Ultra (20 FPS) is not recommended for any gameplay scenario. The minimum FPS at Medium (27 FPS) suggests that even the average of 32 FPS will involve noticeable stuttering during busy scenes in Rust, such as when multiple players are constructing bases or during radiation zone transitions.

At 4K, no settings level provides a playable experience. Low settings (28 FPS) is the best case, but even this falls below 30 FPS average, and the minimum FPS at Medium (16 FPS) indicates severe frame pacing issues. The 12 FPS average at Ultra is effectively a slideshow and should be avoided entirely.

The data suggests that users should prioritize Low settings at 1080p for the best balance of visual clarity and gameplay smoothness. This configuration provides 69 FPS average, which is more than double the frame rate of Medium settings at 1440p (32 FPS) and nearly six times the frame rate of Ultra at 4K (12 FPS). The jump from Low to Medium at 1080p costs 23 FPS (69 to 46), which is a 33% reduction in performance for a modest visual improvement. Given the GPU's limitations, the visual quality difference between Low and Medium is unlikely to justify the significant frame rate penalty. For users who require higher resolutions, Low settings at 1440p (48 FPS) is the only viable option, but it still falls short of the 60 FPS target that modern displays expect.
