Rust

The AMD Ryzen 7 3700X paired with the NVIDIA GeForce RTX 4070 SUPER delivers a solid 1080p and 1440p experience in Rust, but the data shows that 4K Ultra settings push this combination beyond its comfort zone. This analysis breaks down the measured frame rates, settings scaling, and what the CPU brings to the table.

Resolution Scaling

The measured FPS data reveals a clear pattern of diminishing returns as resolution increases, with the most dramatic drop occurring at the highest settings. At 1080p Ultra, the combo produces 109.9 FPS, which falls to 75.4 FPS at 1440p Ultra, and then plummets to 43.3 FPS at 4K Ultra. That represents a 31% loss from 1080p to 1440p, and another 43% loss from 1440p to 4K. These steep declines at Ultra settings point to the GPU becoming the primary bottleneck as pixel count rises, since the RTX 4070 SUPER’s 12 GB of GDDR6X memory and 192-bit bus are being taxed heavily at 4K.

The scaling story changes when you drop to Low settings. At 1080p Low, the system hits 155.6 FPS, which only falls to 139.5 FPS at 1440p Low (a 10% reduction), and then to 103.7 FPS at 4K Low (a 26% reduction from 1440p). The much gentler curve at Low settings suggests the CPU is doing more of the heavy lifting in these scenarios. The Ryzen 7 3700X’s 8 cores and 16 threads are sufficient to keep frame rates high even at 4K when graphical load is minimal, but the RTX 4070 SUPER’s raw throughput becomes the limiting factor once you raise the quality presets.

Medium settings show an intermediate behavior. From 1080p to 1440p, the drop is only from 135.9 FPS to 118.1 FPS (13%), but moving to 4K Medium brings a larger 42% reduction to 68.1 FPS. High settings follow a similar trajectory: 123.7 FPS at 1080p, 98.5 FPS at 1440p, and 59.8 FPS at 4K. The data indicates that for this game, the RTX 4070 SUPER starts to hit its limits around 1440p on higher presets, while the CPU remains capable of feeding frames well beyond what the GPU can render at 4K.

Settings Recommendations

Based on the measured rows, the sweet spot for this combination is 1440p with High settings. The 98.5 FPS average at this preset is smooth for a survival game where quick reactions matter, and it keeps visual quality high without the steep performance penalty seen at Ultra. Pushing to 1440p Ultra costs 23 FPS (from 98.5 down to 75.4) for what is typically a marginal visual gain in Rust, which is a poor trade-off given the game’s art style.

At 1080p, the recommendation shifts to Medium or High. Medium delivers 135.9 FPS, which is well above the refresh rate of most standard monitors, while High still offers 123.7 FPS. Ultra at 1080p drops to 109.9 FPS, which is playable but not worth the extra GPU load when the visual differences between High and Ultra are often subtle in Rust. For players targeting high refresh rates, 1080p Low at 155.6 FPS is the only preset that approaches 144Hz-class performance, but the visual downgrade is significant.

The 4K options are more limited. High at 4K produces 59.8 FPS, which is borderline for a smooth experience, while Medium at 68.1 FPS is playable but not ideal. Ultra at 4K is effectively unusable at 43.3 FPS. The data suggests that 4K gaming with this combo requires sticking to Medium or High, and even then, frame pacing may suffer in busy scenes with many players or complex bases.

FAQ

Q: Can this combo handle 4K gaming in Rust?

A: Yes, but only at Medium or High settings. The measured data shows 68.1 FPS at 4K Medium and 59.8 FPS at 4K High, which are playable. Ultra at 4K drops to 43.3 FPS, which is too low for smooth gameplay.

Q: What is the best preset for competitive play?

A: For maximum responsiveness, 1080p Low delivers 155.6 FPS. If you prefer a balance, 1440p Medium at 118.1 FPS or High at 98.5 FPS are strong options that still respect the game’s visual depth.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: At 1080p Low, the 155.6 FPS figure suggests the Ryzen 7 3700X is keeping up well, but as you raise settings to Ultra (109.9 FPS), the GPU takes over as the bottleneck. The CPU’s 8 cores and 16 threads are not holding back performance at this resolution.

Q: How does the RTX 4070 SUPER compare to its nearest rivals in raw benchmarks?

A: The GPU’s average benchmark score is 42576, which is within 0.3% of the NVIDIA RTX A6000 and AMD Radeon RX 7650 GRE. It sits 1.4% above the AMD Radeon Pro 580X, showing it is a mid-range performer relative to these comparison points.

Q: What does the combo’s rank in Rust tell us?

A: This combination ranks 434 out of 1717 tested combos, placing it in the top 25% of all systems tested for this game. That is a strong showing, but it indicates there are many faster configurations for Rust specifically.

Q: Does the CPU’s single-thread performance matter for Rust?

A: Yes, the Ryzen 7 3700X scores 2694 in Cinebench R23 single-core and 2656 in Passmark single-thread, which are respectable numbers. Rust relies on single-thread performance for its physics and world simulation, so these scores help maintain high frame rates at lower resolutions.

How This Combo Ranks

The combo ranks 434 out of 1717 tested combinations for Rust, which places it in the upper quartile of all systems measured. This is a strong result, but not a top-tier one. The ranking reflects the balance between the Ryzen 7 3700X’s 85th percentile standing among all CPUs and the RTX 4070 SUPER’s 84th percentile among all GPUs. Neither component is exceptional by modern standards, but together they form a coherent mid-range-to-upper-mid-range package.

Looking at the CPU’s nearest rivals, the Ryzen 7 3700X scores 28631 on average, which is nearly identical to the Intel Core i5-12600 (28654, delta -0.1%) and the Intel Core i5-12600H (28666, delta -0.1%). It edges out the AMD Ryzen 5 5600XT (28591, delta 0.1%) and the AMD EPYC 7203P (28583, delta 0.2%). This means the 3700X is competitively positioned, but its age shows in the fact that it trades blows with newer mid-range chips rather than decisively beating them.

For Rust specifically, the 434th rank out of 1717 combos suggests that while this system is capable, there are over 400 faster configurations. Those likely include newer CPUs with higher single-thread performance and GPUs with more bandwidth. The RTX 4070 SUPER’s 84th percentile GPU ranking is solid, but its 12 GB VRAM and 504.2 GB/s bandwidth are not class-leading, which limits performance at 4K Ultra.

CPU Role

The AMD Ryzen 7 3700X is a Zen 2 architecture processor built on TSMC’s 7 nm process, featuring 8 cores and 16 threads. Its base clock of 3.60 GHz boosts to 4.40 GHz, and it carries 32 MB of L3 cache. In Cinebench R23, it scores 19087 in multi-core and 2694 in single-core, while Passmark shows 22458 in multi-thread and 2656 in single-thread. These numbers place it at the 85th percentile of all CPUs, which is respectable for a processor released in 2019.

In Rust, the CPU’s role is most evident at lower resolutions and settings. The jump from 1080p Low (155.6 FPS) to 1080p Medium (135.9 FPS) is only 13%, suggesting the GPU is still the primary driver even at 1080p. However, the fact that 4K Low (103.7 FPS) is only 33% slower than 1080p Low indicates the CPU is capable of maintaining high frame rates regardless of resolution when graphical load is light. The 3700X’s 8-core, 16-thread configuration handles Rust’s multi-threaded world simulation well, and its 2694 single-core score ensures that the game’s physics-heavy single-threaded tasks do not become a bottleneck.

The CPU’s 65W TDP and 51.2 GB/s memory bandwidth are modest, but they are sufficient for Rust’s requirements. The data shows that at 4K Ultra, the frame rate drops to 43.3 FPS, which is a GPU limitation rather than a CPU one. Even a faster CPU would not meaningfully improve 4K Ultra performance given the RTX 4070 SUPER’s bandwidth constraints. Conversely, at 1080p Low, the 155.6 FPS ceiling is likely near the CPU’s practical limit, as single-thread performance becomes the binding constraint in lightly-loaded GPU scenarios.

Measured FPS Breakdown

The complete measured FPS dataset for Rust with this combo is as follows:

At 1920x1080:

• Low: 155.6 FPS average
• Medium: 135.9 FPS average
• High: 123.7 FPS average
• Ultra: 109.9 FPS average

At 2560x1440:

• Low: 139.5 FPS average
• Medium: 118.1 FPS average
• High: 98.5 FPS average
• Ultra: 75.4 FPS average

At 3840x2160:

• Low: 103.7 FPS average
• Medium: 68.1 FPS average
• High: 59.8 FPS average
• Ultra: 43.3 FPS average

The 1080p numbers show a tight spread from 155.6 FPS down to 109.9 FPS, which means even Ultra settings remain playable. The 1440p results are more varied, with Low offering 139.5 FPS and Ultra dropping to 75.4 FPS. The 4K data is where the GPU’s limitations become obvious, with a 60 FPS average only achievable at Low settings, and Ultra falling below 45 FPS.

The scaling from Low to Ultra at each resolution is instructive. At 1080p, Ultra is 29% slower than Low. At 1440p, Ultra is 46% slower. At 4K, Ultra is 58% slower. This progressive widening indicates that the RTX 4070 SUPER’s 35.48 TFLOPS of FP32 performance and 504.2 GB/s bandwidth are insufficient for the demands of 4K Ultra in Rust, while at 1080p the card has enough headroom to absorb the additional load from higher presets.
