Rust

The AMD Ryzen 7 5700X3D and Intel Arc B570 combination delivers a playable 1080p experience in Rust, but struggles significantly at higher resolutions. This pairing, ranked 2349th out of 2953 tested combos, demonstrates a clear GPU bottleneck at 4K while showing balanced performance at 1080p.

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

The AMD Ryzen 7 5700X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer. It operates with a base clock of 3.00 GHz and a boost clock of 4.10 GHz, drawing 105 W TDP. The chip features 96 MB of shared L3 cache, which is substantial and beneficial for games like Rust that rely heavily on repetitive memory access patterns. Its 7 nm process node from TSMC houses 8,850 million transistors on a 74 mm² die.

Benchmark data shows this CPU performs strongly in multi-threaded workloads. In Cinebench R23, it scores 22,366 points multi-core and 3,157 points single-core. Geekbench results show 11,086 multi-core and 1,849 single-core. The 3DMark 16-thread test yields 6,764, while 2-thread and single-thread scores are 1,575 and 804, respectively. PassMark multithread score reaches 26,318, with single-thread at 2,970. These figures place the CPU in the 77th percentile of all CPUs.

The CPU's nearest rivals include the AMD Ryzen 5 7600X3D with an average score of 24,728 (0.1% higher), the AMD Ryzen 9 5900HX at 24,822 (0.5% higher), the Intel Core i5-12450HX at 24,576 (0.5% lower), and the Intel Core i5-11600 at 24,563 (0.6% lower). The Ryzen 7 5700X3D sits within 0.6% of all these processors, indicating near-identical synthetic CPU performance.

For Rust specifically, the data suggests the CPU is not the primary limiting factor at 1080p. At 1920x1080 with Low settings, the combo achieves 118 FPS average. The jump from Low to Medium at 1080p drops the average to 79 FPS, a 39 FPS reduction. This scaling pattern indicates that the game becomes more demanding on the GPU as settings increase, but the CPU maintains sufficient headroom. The 3DMark 8-thread score of 5,357 and max-thread score of 6,755 suggest the processor handles the multi-threaded nature of Rust's simulation and entity updates effectively.

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

The Intel Arc B570 is built on the Xe2-HPG architecture, codenamed Battlemage (Arc 5), using TSMC's 5 nm process. The chip, designated BMG-G21, contains 19,600 million transistors on a 272 mm² die. It operates at a fixed clock speed of 2500 MHz for both base and boost, with memory running at 2375 MHz (19 Gbps effective).

The GPU features 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s bandwidth. It has 2,304 shading units, 144 TMUs, and 80 ROPs, along with 18 ray tracing cores.

Geekbench OpenCL score reaches 83,514, while Vulkan score is 96,844. The GPU's average benchmark score is 20,556, placing it in the 65th percentile of all GPUs.

The GPU's nearest rivals are the NVIDIA GeForce RTX 3070 Mobile (0.1% higher), Intel Arc A750 (0.1% lower), NVIDIA Quadro M4000M (0.4% higher), and AMD Radeon R9 M390X (0.5% lower). These deltas are extremely tight, showing the Arc B570 performs comparably to these cards in aggregate benchmarks.

In Rust, the GPU's role becomes evident when examining frame rate scaling across resolutions. At 1080p Low, the system hits 118 FPS average, but at 4K Low, it drops to 48 FPS. This 70 FPS decline highlights the GPU's memory bandwidth and compute constraints at higher pixel counts. The 10 GB VRAM capacity is sufficient for Rust's texture requirements, but the 160-bit bus and 380 GB/s bandwidth limit performance at 4K where pixel throughput demands are highest.

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

The measured data shows a clear pattern of frame rate degradation as resolution increases, which reveals the bottleneck characteristics of this combo. At Low settings, the average FPS drops from 118 at 1920x1080 to 81 at 2560x1440, then to 48 at 3840x2160. This represents a 31.4% drop from 1080p to 1440p, and a further 40.7% drop from 1440p to 4K. The cumulative reduction from 1080p to 4K is 59.3%.

For Medium settings, the progression is 79 FPS at 1080p, 54 FPS at 1440p, and 32 FPS at 4K. The min FPS at 1080p Medium is 67, and at 1440p Medium it is 46, while at 4K Medium it drops to 27. These minimum frame rates indicate that even the lowest dips remain above 60 FPS only at 1080p Medium, but fall below playable thresholds at higher resolutions.

High settings show 67 FPS at 1080p, 46 FPS at 1440p, and 27 FPS at 4K. The drop from 1080p to 1440p is 21 FPS (31.3%), and from 1440p to 4K is 19 FPS (41.3%). Ultra settings follow the same trend: 51 FPS at 1080p, 35 FPS at 1440p, and 21 FPS at 4K.

The resolution scaling data strongly indicates a GPU bottleneck at 1440p and especially 4K. The CPU's strong multi-threaded performance, evidenced by its Cinebench R23 multi-core score of 22,366, can keep up with the game's logic at all resolutions. However, the GPU's rendering throughput, capped by its 11.52 TFLOPS FP32 and 380 GB/s bandwidth, cannot maintain high frame rates when pixel count quadruples from 1080p to 4K. The fact that Low settings at 4K (48 FPS) barely exceed 1080p Ultra (51 FPS) shows the GPU is the limiting component at high resolutions.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of AMD Ryzen 7 5700X3D and Intel Arc B570 ranks 2349th out of 2953 tested combos in Rust. This places the combo in the bottom 20.5% of all tested configurations, which is notable given the individual component rankings. The CPU ranks in the 77th percentile, while the GPU sits in the 65th percentile, yet their combined performance in Rust falls well below what those individual rankings might suggest.

The low combo rank indicates that this pairing is not well-suited for Rust's performance demands. The game appears to favor configurations with stronger GPU throughput, as evidenced by the steep frame rate declines at higher resolutions. The combo's rank suggests that many other CPU-GPU pairings, even those with individually lower-ranked components, achieve better Rust performance.

Comparatively, the CPU's nearest rivals all have average scores within 0.6% of the Ryzen 7 5700X3D, meaning CPU choice among these options would have minimal impact on Rust performance. Similarly, the GPU's nearest rivals are all within 0.5% of the Arc B570's average score. This implies that the combo's low rank is not due to an unusually weak individual component, but rather the combination's overall characteristics when running Rust.

The measured data confirms Rust is demanding on both components, but the GPU bottleneck dominates at 1440p and 4K. At 1080p, the combo achieves playable frame rates across all settings, with Low hitting 118 FPS and Ultra reaching 51 FPS. However, at 4K, even Low settings only reach 48 FPS, which is below the 60 FPS threshold many players consider acceptable. This performance profile explains the low combo rank, as Rust players often require high frame rates for competitive gameplay.

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

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and desired frame rate. At 1920x1080, the Medium preset provides the best balance of visual quality and performance. The average FPS of 79 with a minimum of 67 ensures smooth gameplay without sacrificing too much visual fidelity. The High preset at 67 FPS average is also viable, but the 12 FPS advantage of Medium makes it the safer choice for maintaining consistent frame rates.

At 2560x1440, the Low preset is the only option that maintains an average above 60 FPS, hitting 81 FPS. The Medium preset drops to 54 FPS average with a 46 FPS minimum, which may cause noticeable stuttering in fast-paced situations. For players who prioritize smoothness over visuals, Low is the recommended choice at this resolution. Those who can tolerate sub-60 FPS may consider Medium, but the minimum frame rate of 46 suggests potential judder.

At 3840x2160, all presets fail to reach 60 FPS average. The Low preset at 48 FPS is the highest achievable, followed by Medium at 32 FPS, High at 27 FPS, and Ultra at 21 FPS. For 4K gaming, the Low preset is the only reasonable option, and even then, the 48 FPS average may not satisfy players accustomed to higher refresh rates. Players at this resolution should consider lowering resolution or accepting reduced visual settings.

The Ultra preset is not recommended at any resolution. At 1080p it achieves 51 FPS, at 1440p it drops to 35 FPS, and at 4K it falls to 21 FPS. The visual improvement from High to Ultra does not justify the significant frame rate penalty across all resolutions. The data shows that High settings provide only a marginal visual upgrade over Medium while costing 12 to 14 FPS at 1080p and 1440p, making Medium the sweet spot for most users.

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

At 1920x1080, the measured average frame rates are: Low 118 FPS, Medium 79 FPS with minimum 67 and maximum 91, High 67 FPS, and Ultra 51 FPS. The Medium setting provides the only minimum frame rate data at this resolution, showing a 12 FPS difference between average and minimum, which indicates some frame time variance.

At 2560x1440, the measured average frame rates are: Low 81 FPS, Medium 54 FPS with minimum 46 and maximum 62, High 46 FPS, and Ultra 35 FPS. The Medium minimum of 46 FPS is 8 FPS below the average, while the maximum of 62 FPS shows the system can occasionally reach higher frame rates. The gap between Low and Medium at this resolution is 27 FPS, the largest jump between consecutive settings.

At 3840x2160, the measured average frame rates are: Low 48 FPS, Medium 32 FPS with minimum 27 and maximum 37, High 27 FPS, and Ultra 21 FPS. The Medium setting again provides min/max data, showing a 5 FPS spread between minimum and average. The difference between Low and Medium at 4K is 16 FPS, while Medium to High is 5 FPS, and High to Ultra is 6 FPS.

The data reveals that the frame rate scaling factor from 1080p to 4K varies by preset: Low drops by 59.3%, Medium by 59.5%, High by 59.7%, and Ultra by 58.8%. This consistent reduction across all presets confirms the GPU bottleneck is resolution-dependent rather than settings-dependent. The average FPS at 4K Low (48) is nearly identical to 1080p High (67) when accounting for the resolution difference, further emphasizing the GPU's limited high-resolution capability.
