Rust

The AMD Ryzen 7 3700X paired with the NVIDIA GeForce RTX 4070 delivers a robust 1080p and 1440p experience in Rust, though 4K Ultra presents a significant challenge. This combination ranks in the 68th percentile of tested combos, with the benchmark data revealing a system that is well-balanced at lower resolutions but becomes GPU-limited as pixel count and graphical fidelity rise.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate drops from 126 FPS at 1080p to 88 FPS at 1440p, a reduction of 38 FPS, and then further to 52 FPS at 4K, another 36 FPS decline. This progression indicates that the RTX 4070 is the primary bottleneck at higher resolutions, as the performance cost of rendering more pixels directly impacts the frame rate.

At Low settings, the scaling is even more pronounced in absolute terms. The system achieves 156 FPS at 1080p, 137 FPS at 1440p, and 91 FPS at 4K. The drop from 1080p to 1440p is only 19 FPS, while the jump to 4K costs 46 FPS. This suggests that at 1080p Low, the CPU is able to keep the GPU well-fed, but the 4K workload overwhelms the graphics card, causing a steeper performance cliff than seen at higher settings where the GPU is already under more strain.

The Medium settings data, which includes min/max FPS values, provides additional insight into frame time consistency. At 1080p Medium, the average is 134 FPS with a minimum of 114 FPS and maximum of 154 FPS, showing a tight 40 FPS spread. At 1440p Medium, the average is 104 FPS with a minimum of 88 FPS and a maximum of 120 FPS. At 4K Medium, the average falls to 61 FPS, with a minimum of 52 FPS and maximum of 71 FPS. The relative stability of these ranges suggests that the game is not experiencing severe stuttering, but the overall headroom diminishes significantly at 4K.

Interpreting these results, the limiting component shifts with resolution. At 1080p, the system is likely CPU-bound in certain scenarios, as the 156 FPS Low result is close to what the Ryzen 7 3700X can push in this title. As resolution increases, the GPU becomes the clear limiting factor, particularly at 4K Ultra where the average FPS falls to 39. The data indicates that for smooth 4K gameplay, users would need to rely on lower settings or accept sub-60 FPS averages, as even Medium settings only achieve 61 FPS.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with a 5 nm process node and features 12 GB of GDDR6X memory on a 192-bit bus, providing a memory bandwidth of 504.2 GB/s. The GPU operates at a base clock of 1920 MHz with a boost clock of 2475 MHz. This memory configuration is sufficient for Rust at 1080p and 1440p, as the measured FPS values suggest the 12 GB frame buffer is not a limiting factor at those resolutions.

However, at 4K resolution, the GPU's role becomes more critical. The benchmark results show that the RTX 4070 struggles to maintain high frame rates at 4K Ultra, averaging only 39 FPS. This is not necessarily a VRAM capacity issue, as Rust is not typically a VRAM-heavy title, but rather a raw compute limitation. The GPU's 5888 shading units and 64 ROPs are tasked with rendering over 8 million pixels at 4K, which explains the significant performance drop from 1440p.

The GPU's benchmark scores place it in the 81st percentile of all GPUs, with an average score of 37648. Its nearest rivals include the NVIDIA Tesla P4, which scores 37628 (a 0.1% delta), and the AMD Radeon RX Vega 56, which scores 37507 (a 0.4% delta). Notably, the RTX 4080 Mobile scores 38135, which is 1.3% higher, indicating that the desktop RTX 4070 is slightly behind its mobile sibling in raw compute despite its higher power envelope. The GPU's PassMark G3D score of 26927 and DirectX 12 score of 103 reflect its strong overall performance, but Rust's engine appears to be more sensitive to raw rasterization throughput than to specific feature sets.

The data shows that the RTX 4070 is a capable 1440p card for Rust, delivering 88 FPS at High settings, but 4K gaming requires significant settings reductions. The transition from 1440p High (88 FPS) to 4K High (52 FPS) represents a 41% performance drop, highlighting the GPU's limitations at higher pixel densities.

How This Combo Ranks

This specific combination of AMD Ryzen 7 3700X and NVIDIA GeForce RTX 4070 ranks 1179 out of 3723 tested combos in Rust, placing it in the 68th percentile of all tested systems. This ranking reflects the balance between the CPU and GPU, as the Ryzen 7 3700X is an older Zen 2 architecture processor that may not fully unlock the RTX 4070's potential in all scenarios.

The CPU itself has an average benchmark score of 34260, placing it in the 84th percentile of all CPUs. Its nearest rivals include the AMD Ryzen AI 7 350, which scores 34222 (a 0.1% delta), and the AMD EPYC 4244P, which scores 34220 (a 0.1% delta). The Intel Core i5-13450HX scores 34333, which is 0.2% higher, while the Intel Core Ultra 7 165H scores 34083, which is 0.5% lower. These close scores indicate that the Ryzen 7 3700X is competitive with newer mid-range processors in synthetic benchmarks, but its gaming performance may be limited by its lower single-thread performance relative to newer architectures.

The combination ranking of 1179 out of 3723 suggests that while this setup is above average, it is not in the top tier of tested configurations. This is likely due to the CPU's age relative to the GPU, as newer processors with higher IPC and faster memory support could extract more performance from the RTX 4070. The data implies that users with this combo are getting solid performance, but there is headroom for improvement by pairing the GPU with a more modern CPU.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings levels. At 1920x1080, the system delivers an average of 156 FPS at Low settings, 134 FPS at Medium, 126 FPS at High, and 97 FPS at Ultra. The Medium setting shows a minimum of 114 FPS and a maximum of 154 FPS, indicating a stable experience even during intense gameplay moments.

At 2560x1440, the performance scales down as expected. Low settings yield 137 FPS, Medium delivers 104 FPS (with a minimum of 88 FPS and maximum of 120 FPS), High achieves 88 FPS, and Ultra drops to 67 FPS. The 1440p results show that High settings are playable for most users, but those seeking higher frame rates would need to use Medium or Low settings.

At 3840x2160, the RTX 4070 begins to show its limits. Low settings produce 91 FPS, which is playable, but Medium drops to 61 FPS (with a minimum of 52 FPS and maximum of 71 FPS), High falls to 52 FPS, and Ultra averages just 39 FPS. The 4K Ultra result is below the standard 60 FPS threshold, suggesting that this combo is not ideal for maximum fidelity 4K gaming in Rust.

The pattern across all resolutions is consistent: the gap between Low and Ultra settings narrows as resolution increases. At 1080p, the difference between Low (156 FPS) and Ultra (97 FPS) is 59 FPS. At 1440p, the difference is 70 FPS (137 vs 67). At 4K, the difference is 52 FPS (91 vs 39). This suggests that at lower resolutions, the CPU is more involved in the performance equation, while at 4K, the GPU dominates the frame rate ceiling.

CPU Role

The AMD Ryzen 7 3700X is an 8-core, 16-thread processor based on the Zen 2 architecture (codenamed Matisse), manufactured on a 7 nm process by TSMC. It has a base clock of 3.60 GHz and a boost clock of 4.40 GHz, with a 65W TDP. The CPU features 32 MB of L3 cache and 512 KB of L2 cache per core, along with 64 KB of L1 cache per core. Memory support is limited to DDR4 with a dual-channel bus, providing 51.2 GB/s of bandwidth.

In Rust, the CPU's role is significant at lower resolutions where the GPU is not the bottleneck. The 1080p Low setting result of 156 FPS suggests that the Ryzen 7 3700X is capable of feeding the RTX 4070 at this resolution, but the frame rate ceiling appears to be around this level. At 1080p Ultra, the average drops to 97 FPS, indicating that the GPU is still the primary limiter even at lower resolutions when settings are maxed.

The CPU's PassMark single-thread score of 2656 and Geekbench single-core score of 1593 are modest by modern standards, which could explain why the system does not achieve higher frame rates in Rust's CPU-bound scenarios. Rust is known to be sensitive to single-thread performance, and the Zen 2 architecture's lower IPC compared to newer processors may limit performance in certain situations. However, the multithreaded performance is solid, with a Cinebench R15 multicore score of 2092 and a Geekbench multicore score of 8899.

The CPU's percentile ranking of 84% among all CPUs indicates it is still a capable processor, but its nearest rivals include newer parts like the AMD Ryzen AI 7 350 and Intel Core i5-13450HX. The 0.1-0.5% benchmark deltas show that the Ryzen 7 3700X remains competitive in synthetic tests, but real-world gaming performance may diverge due to architectural differences. For users with this combo, the data suggests that upgrading the CPU could yield higher frame rates in Rust, particularly at 1080p where the CPU is more likely to be the limiting factor.
