# AMD Ryzen 7 5700G + NVIDIA GeForce RTX 4070 — Rust Performance Analysis

This pairing of AMD's Ryzen 7 5700G and NVIDIA's GeForce RTX 4070 delivers a mixed bag for Rust, with playability depending heavily on resolution and settings. The measured frame rates show a system that excels at 1080p and 1440p, but struggles to maintain a smooth 60 FPS at 4K on the most demanding presets. The data indicates a CPU that sits in the 79th percentile among all processors and a GPU in the 81st percentile, suggesting both components are well above average, yet Rust's demanding nature at higher resolutions exposes the limits of this combination.

Best Settings per Resolution

At 3840x2160 (4K), the most demanding preset that maintains at least 60 FPS is Medium, delivering an average of 62.8 FPS. This narrowly clears the playability threshold, leaving little headroom for demanding scenes. The High preset drops to 51.5 FPS, which falls below the 60 FPS target, while Ultra bottoms out at 41.2 FPS. Low settings at 4K achieve 91.2 FPS, but the Medium preset represents the best balance of visual quality and performance.

At 2560x1440 (1440p), the system can handle Ultra settings while staying above 60 FPS, with an average of 69.2 FPS. This is the sweet spot for this combo — all four presets (Low, Medium, High, Ultra) remain playable, with High hitting 89.2 FPS and Medium reaching 105.3 FPS. The 1440p Ultra experience provides a comfortable margin above the threshold, making this resolution the highest where visual quality doesn't compromise playability.

At 1920x1080 (1080p), Ultra settings are viable with an average of 99.6 FPS. This resolution offers the most headroom, with High at 129.5 FPS, Medium at 150.6 FPS, and Low reaching 193.8 FPS. Even the most demanding preset clears the 60 FPS target by nearly 40 frames, indicating that 1080p is where this combo truly shines for competitive play.

CPU and GPU Roles

The performance scaling across resolutions reveals how the workload shifts between components. At 1080p, the GPU is under less pressure, allowing the CPU to drive higher frame rates — Low settings produce 193.8 FPS, which is 94% higher than the 99.6 FPS at Ultra. This 94% spread between presets indicates that at 1080p, both components contribute significantly, but the GPU's rendering load is the primary variable.

Moving to 1440p, the gap between Low (157.5 FPS) and Ultra (69.2 FPS) widens to 128%, showing that the GPU's workload increases substantially. The CPU still has enough headroom to push high frame rates at lower settings, but the GPU becomes the limiting factor as quality increases. The Ryzen 7 5700G's 8 cores and 16 threads (with a 4.60 GHz boost clock) provide adequate processing power, as evidenced by the 1440p Low setting still exceeding 150 FPS.

At 4K, the GPU is clearly the bottleneck. The difference between Low (91.2 FPS) and Ultra (41.2 FPS) is a 121% swing, but even at Low settings, the frame rate drops to roughly half of what the same preset achieves at 1080p (193.8 FPS). This halving of performance from 1080p to 4K at identical settings points to the RTX 4070's pixel throughput limits — its 158.4 GPixel/s pixel rate and 504.2 GB/s memory bandwidth are strained at 4K resolution. The CPU's role diminishes at 4K, as the GPU's rendering time dominates the frame budget.

The data suggests that at 1080p and 1440p, this is a balanced pairing where both components matter, but at 4K, the RTX 4070 becomes the clear limiting factor. The CPU's 16 MB of L3 cache and Zen 3 architecture provide sufficient single-thread performance for Rust's simulation and networking, but the GPU's memory bandwidth and pixel processing capabilities determine the ceiling at higher resolutions.

How This Combo Ranks

This specific combination ranks 909th out of 3,723 tested configurations in Rust, placing it in the top 24% of all tested combos. While this percentile is respectable, it's notable that the individual components rank higher — the CPU at the 79th percentile and the GPU at the 81st percentile. This discrepancy suggests that Rust's engine doesn't fully utilize the strengths of either component, or that the pairing introduces some inefficiency.

The rank indicates that many other combinations deliver better Rust performance, likely due to more powerful GPUs or CPUs with higher single-thread performance. However, a 909th rank out of 3,723 combos means this system outperforms roughly 75% of tested configurations, which is solid for mainstream gaming. The ranking reflects that while this combo can handle Rust well at 1080p and 1440p, it's not positioned among the elite performers that would push 4K Ultra at high frame rates.

FAQ

Q: Can this PC run Rust at 4K with maximum settings?

A: The data indicates GPU limitation at 1440p. From Low (157.5 FPS) to Ultra (69.2 FPS), there's a 128% performance drop, showing that increasing visual quality impacts the GPU heavily. The CPU maintains high frame rates at lower settings, but the GPU becomes the constraint as quality rises.

Measured FPS Breakdown

3840x2160 (4K):

• Low: 91.2 FPS average
• Medium: 62.8 FPS average
• High: 51.5 FPS average
• Ultra: 41.2 FPS average

2560x1440 (1440p):

• Low: 157.5 FPS average
• Medium: 105.3 FPS average
• High: 89.2 FPS average
• Ultra: 69.2 FPS average

1920x1080 (1080p):

• Low: 193.8 FPS average
• Medium: 150.6 FPS average
• High: 129.5 FPS average
• Ultra: 99.6 FPS average

The measured data shows consistent scaling: across all resolutions, Low settings deliver roughly 90-94% more FPS than Ultra. The pattern also reveals that resolution scaling is nearly linear — moving from 1080p to 1440p at the same preset reduces frame rate by about 18-20%, while moving to 4K reduces it by roughly 53-54% compared to 1080p. This non-linear drop at 4K underscores the GPU's pixel throughput limitations.

The Verdict

This PC can run Rust at playable frame rates across all three tested resolutions, but with important caveats. At 1920x1080, every preset — Low, Medium, High, and Ultra — clears the 60 FPS threshold, with Ultra averaging 99.6 FPS. This is the most comfortable experience.

At 2560x1440, all four presets also remain above 60 FPS, with Ultra achieving 69.2 FPS. This resolution offers the best combination of visual fidelity and performance, as the highest settings stay playable with a reasonable margin.

At 3840x2160, only Low (91.2 FPS) and Medium (62.8 FPS) meet the 60 FPS target. High (51.5 FPS) and Ultra (41.2 FPS) fall short, meaning players at 4K must compromise on visual quality to maintain smooth gameplay.

The verdict is clear: this combo is fully capable for 1080p and 1440p gaming, including at maximum settings, but 4K Ultra is not feasible. The RTX 4070's 12 GB of GDDR6X memory and 504.2 GB/s bandwidth are sufficient for 1440p Ultra, but the 4K pixel workload exceeds what the GPU can render while maintaining 60 FPS on higher presets.

Similar Performance Alternatives

For the CPU, the nearest rivals to the Ryzen 7 5700G include the Intel Core i9-9900K, which scores 27,097 (0.2% higher), the Intel Core i5-14400T at 27,166 (0.4% higher), and the AMD Ryzen AI 7 445 at 26,936 (0.4% lower). These processors would deliver virtually identical Rust performance, with differences well within measurement noise. Players upgrading from any of these CPUs would see no meaningful change in frame rates.

For the GPU, the closest competitors to the RTX 4070 are the NVIDIA GeForce RTX 4080 Mobile at 38,135 (1.3% faster), the NVIDIA Tesla P4 at 37,628 (0.1% faster), the AMD Radeon RX Vega 56 at 37,507 (0.4% slower), and the AMD Radeon PRO W6400 at 37,157 (1.3% slower). The RTX 4080 Mobile's slight edge would translate to a few extra FPS in Rust, while the RX Vega 56 would perform nearly identically. These alternatives suggest that users with any of these GPUs would experience similar gameplay quality, with the RTX 4080 Mobile offering a marginal improvement and the PRO W6400 a marginal decrease.
