Rust

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 3070 delivers a solid 1080p and 1440p experience in Rust, but the data reveals a steep performance cliff at 4K, particularly when settings are pushed to Ultra. This combination demonstrates classic behavior of a high-end GPU being progressively constrained by resolution, with CPU headroom that remains ample at lower settings.

Resolution Scaling

The measured FPS data shows a clear and predictable pattern of performance degradation as resolution increases, but the severity varies dramatically depending on the quality preset. At Low settings, the frame rate drops from 153.4 FPS at 1920x1080 to 128.8 FPS at 2560x1440, a reduction of roughly 16%. Moving to 3840x2160 at Low yields 74.6 FPS, which is a 42% drop from the 1440p figure. This steep decline at 4K indicates that the GPU is becoming the limiting factor, as the pixel throughput requirement outpaces what the RTX 3070 can sustain even with reduced visual fidelity.

High settings tell a similar story with a different starting point. At 1080p High, the combo produces 106.2 FPS, which falls to 74.6 FPS at 1440p High — a 30% reduction. The 4K High result of 42.6 FPS represents another 43% drop from the 1440p number. The consistency of this 42-43% penalty between 1440p and 4K across both Low and High presets suggests a hard GPU bound at that resolution, regardless of how much load is removed from the shading units.

Ultra settings amplify the scaling problem. The combo manages 77.4 FPS at 1080p Ultra, but this plummets to 57.3 FPS at 1440p Ultra and then to a barely playable 32.2 FPS at 4K Ultra. The gap between 1080p and 4K at Ultra is a 58% reduction, the largest percentage drop of any preset. Medium settings sit between these extremes, starting at 125.4 FPS at 1080p, falling to 85.7 FPS at 1440p, and reaching 52.6 FPS at 4K. The scaling pattern strongly suggests that at 1080p, the CPU is still doing meaningful work, while at 4K the RTX 3070's 8 GB frame buffer and memory bandwidth become the dominant constraints.

CPU Role

The Ryzen 5 4600G provides 6 cores and 12 threads based on the Zen 2 architecture, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its multi-threaded capabilities are demonstrated by a Cinebench R23 multicore score of 13593, while single-thread performance reaches 1919 in the same test. These figures place the processor in the 75th percentile among all CPUs, indicating it is a competent mid-range part for gaming workloads.

The CPU's role in Rust becomes evident when examining the performance deltas between settings at the same resolution. At 1080p, the difference between Low and Ultra is substantial — 153.4 FPS versus 77.4 FPS — but the CPU is not the bottleneck at either extreme. The 3DMark scores show a strong scaling from 2 threads (1430) to 8 threads (4138), suggesting the processor handles multi-threaded game logic well. The Passmark multithread score of 15992 and the data compression score of 231426 indicate that background tasks and server communication in Rust will not starve the GPU.

However, the processor's single-thread score of 2653 in Passmark, while respectable, is not exceptional. Rust's simulation and entity update loops are known to be sensitive to single-thread performance, and the 4600G's boost clock of 4.20 GHz provides reasonable but not class-leading responsiveness. The 3DMark single-thread score of 726 reinforces this characterization. The CPU's nearest rivals include the AMD Ryzen 3 PRO 5355GE with an average score of 17482 and a delta of 0%, and the Intel Core i5-12450H at 17475 with a 0.1% delta, showing that this processor sits in a tightly contested performance band.

GPU Role

The RTX 3070 is the dominant component in this pairing, equipped with 8 GB of GDDR6 memory on a 256-bit bus, providing 448.0 GB/s of bandwidth. Its Ampere architecture features 5888 shading units and 184 texture mapping units, with a boost clock of 1725 MHz. The GPU achieves 20.31 TFLOPS of FP32 compute, which is substantial for rasterization-heavy games like Rust.

The GPU's memory configuration becomes a critical factor at 4K Ultra, where the 32.2 FPS result indicates the card is overwhelmed. The 8 GB VRAM capacity is likely a limiting factor at 3840x2160 with Ultra textures, as Rust's asset streaming can exceed this allocation. The memory bandwidth of 448.0 GB/s, while generous for 1080p and 1440p, struggles to feed the pixel pipeline at 4K. The Passmark G3D score of 22214 places this GPU in the 72nd percentile of all graphics cards, with nearest rivals including the AMD Radeon RX 6600 XT (27985, 0.9% delta) and the NVIDIA GeForce GTX 980 Ti (27956, 1% delta), showing it is a strong performer in its class.

The GPU's pixel rate of 165.6 GPixel/s and texture rate of 317.4 GTexel/s explain why 1080p and 1440p results are strong. At 1080p Low, the 153.4 FPS figure suggests the card is nowhere near saturated, leaving the CPU as the potential limiter in lighter scenes. The RTX 3070's DirectX 12 Ultimate support and Vulkan 1.4 API compatibility align well with Rust's rendering requirements, though the game does not heavily leverage ray tracing or tensor cores.

Measured FPS Breakdown

At 1920x1080, the combo delivers playable frame rates across all presets. Low settings produce 153.4 FPS, Medium yields 125.4 FPS, High reaches 106.2 FPS, and Ultra drops to 77.4 FPS. The spread from Low to Ultra is 76 FPS, indicating that the GPU has significant headroom at this resolution. All four presets exceed the 60 FPS threshold, making 1080p the sweet spot for this pairing.

At 2560x1440, the performance remains respectable but the gap between presets narrows. Low achieves 128.8 FPS, Medium hits 85.7 FPS, High falls to 74.6 FPS, and Ultra settles at 57.3 FPS. The Low-to-Ultra spread here is 71.5 FPS, but the absolute values are lower, showing the GPU is working harder. Notably, Ultra dips below 60 FPS, which may require settings adjustments for competitive play.

At 3840x2160, the results are mixed and generally demand compromises. Low produces a playable 74.6 FPS, Medium drops to 52.6 FPS, High reaches 42.6 FPS, and Ultra falls to 32.2 FPS. The 4K Low result is the standout, nearly matching the 1440p High figure of 74.6 FPS. This suggests that players targeting 4K should stick to Low or Medium settings to maintain smooth gameplay, as the higher presets become increasingly unplayable. The data indicates that the RTX 3070 can handle 4K in Rust only with significant visual concessions.

How This Combo Ranks

This specific combination of AMD Ryzen 5 4600G and NVIDIA GeForce RTX 3070 ranks 779th out of 1717 tested combos in Rust, placing it in the upper-middle tier of the database. This ranking reflects the pairing's balanced but not exceptional performance profile — the CPU is competent but not top-tier, while the GPU is strong for 1080p and 1440p but falls short at 4K Ultra.

The rank position suggests that many combinations achieve higher frame rates, likely due to more powerful CPUs that can better feed the RTX 3070 at lower resolutions. The 4600G's integrated Radeon Vega 7 graphics are irrelevant in this configuration since the discrete GPU handles all rendering, but the CPU's 65W TDP and 8 MB of shared L3 cache may limit performance in CPU-bound scenarios. The data shows that the combo's strength lies in its ability to maintain high frame rates at 1080p and 1440p, where the RTX 3070's capabilities are fully utilized, rather than at 4K where the GPU becomes the bottleneck.
