Rust

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 2070 SUPER presents a clear picture in Rust: this is a combination where the graphics card dictates the experience at higher resolutions, while the processor’s strength becomes evident only when the GPU workload is lightened. The measured data shows a system that can handle competitive frame rates at 1080p but struggles to maintain smoothness at 4K, making it a setup that rewards users who prioritize resolution scaling over raw pixel counts.

Resolution Scaling

The transition from 1080p to 4K exposes a severe performance cliff, with the average frame rate dropping by more than half across all settings. At High settings, the average FPS falls from 87.9 at 1920x1080 to 60.6 at 2560x1440, then plummets to 36.9 at 3840x2160. This represents a 42.7% drop from 1080p to 1440p and a further 39.1% drop from 1440p to 4K. The pattern is consistent across the board: Low settings go from 149.6 at 1080p to 106.3 at 1440p and 63.8 at 4K, while Ultra plummets from 63.4 to 45.9 to 26.4.

These numbers indicate that the RTX 2070 SUPER is the limiting component in this pairing. The Ryzen 9 7900X, with its 12 cores and 24 threads, is more than capable of feeding frames; the bottleneck is the GPU’s 8 GB of GDDR6 memory and its 448.0 GB/s bandwidth. The sharpest decline occurs between 1440p and 4K, where the pixel count quadruples, overwhelming the GPU’s shading units and memory bus. At 1080p, the CPU’s high single-thread performance (PassMark single-thread score of 4238) allows the GPU to reach its ceiling, as evidenced by the 149.6 average at Low settings. This is a classic case where lowering resolution shifts the balance from GPU-bound to CPU-bound, but the CPU’s headroom means it never becomes the primary constraint.

How This Combo Ranks

In Rust, this specific CPU-GPU combination ranks 1033 out of 1717 tested combos, placing it in the 60th percentile of all possible pairings. This is a middling result, reflecting the GPU’s age relative to modern hardware. The combo’s rank is dragged down by the RTX 2070 SUPER’s performance, which sits at the 65th percentile versus all GPUs, while the CPU ranks much higher at the 93rd percentile versus all CPUs. The discrepancy is stark: the processor is a top-tier part, but the graphics card is barely above average, creating an imbalance that hurts the overall ranking.

Compared to GPU rivals, the RTX 2070 SUPER’s average benchmark score of 22206 puts it just 0.5% behind the NVIDIA RTX A400 and 2.3% behind the NVIDIA GeForce RTX 4060 Mobile, while it leads the AMD Radeon RX 5700 by 2.5%. This narrow band of performance means the GPU is competitive with its immediate peers, but none of those are particularly strong in modern titles. The CPU, meanwhile, is within 0.8% of the Intel Core i9-13980HX and 0.1% of the Intel Core Ultra 5 235, showing that the processor is not the reason for the combo’s mid-pack ranking.

GPU Role

The RTX 2070 SUPER’s 8 GB of GDDR6 memory is the defining constraint in Rust. The game’s large world and asset streaming demand significant VRAM, and the 256-bit bus width with 448.0 GB/s bandwidth is insufficient to sustain high frame rates at higher resolutions. The card’s boost clock of 1770 MHz and base clock of 1605 MHz are modest by today’s standards, contributing to its 9.062 TFLOPS of FP32 performance. The 64 ROPs and 160 TMUs are also limiting factors when rendering complex scenes.

The measured FPS data highlights this VRAM pressure. At 4K Ultra, the average drops to 26.4 FPS, which is unplayable. Even at 4K Medium, the card only manages 38.6 FPS, indicating that the memory bandwidth is saturated. The GPU’s performance relative to its nearest rivals (0.5% behind the RTX A400, 0.9% ahead of the GTX TITAN Z) shows it is a competent mid-range card from its generation, but it lacks the headroom needed for Rust’s demanding environments. The card’s 12 nm process node and 13,600 million transistors also mean it runs hotter and less efficiently than newer parts, though the data does not quantify thermal impact.

Settings Recommendations

Given the measured results, the optimal experience depends heavily on target resolution. At 1920x1080, High settings deliver a solid 87.9 FPS average, which is ideal for competitive play, while Medium offers 103.3 FPS for those who prefer smoother motion. Low settings at 1080p hit 149.6 FPS, which is excellent for high-refresh-rate monitors, but the visual quality suffers significantly.

For 2560x1440, the data suggests that Medium settings (67.7 FPS) are the sweet spot, offering a playable frame rate without sacrificing too much visual fidelity. High settings at 1440p drop to 60.6 FPS, which is borderline for fast-paced action, while Ultra at 45.9 FPS is too choppy for consistent gameplay. At 3840x2160, no setting provides a smooth experience: the best option is Low at 63.8 FPS, which is technically playable but visually poor. Medium at 38.6 FPS and High at 36.9 FPS are both below the 40 FPS threshold many consider minimum, and Ultra at 26.4 FPS is unusable. The recommendation is to stick to 1080p or 1440p with Medium or High settings, avoiding 4K unless the user accepts Low settings.

Measured FPS Breakdown

At 1920x1080, the performance ladder is steep but predictable. Low settings produce an average of 149.6 FPS, which is the highest measured value in the entire dataset. Medium drops to 103.3 FPS, a 31% reduction. High further reduces to 87.9 FPS, and Ultra bottoms out at 63.4 FPS. The gap between Low and Ultra is 86.2 FPS, showing that the GPU scales well with settings at this resolution.

Moving to 2560x1440, the averages compress: Low yields 106.3 FPS, Medium 67.7 FPS, High 60.6 FPS, and Ultra 45.9 FPS. The delta between Low and Ultra shrinks to 60.4 FPS, indicating the GPU is becoming the constraint. At 3840x2160, the values are tightly clustered and low: Low produces 63.8 FPS, Medium 38.6 FPS, High 36.9 FPS, and Ultra 26.4 FPS. The difference between Low and Ultra is only 37.4 FPS, demonstrating that the GPU is fully saturated and settings have diminishing returns.

The data reveals a consistent pattern: the percentage drop from 1080p to 4K is approximately 57% for Low, 63% for Medium, 58% for High, and 58% for Ultra. This uniformity suggests that the bottleneck is primarily memory bandwidth rather than compute, as all settings suffer similar proportional losses.

FAQ

Q: Is this combo capable of 1440p gaming in Rust?

A: Yes, but only at Medium or High settings. The measured average FPS at 2560x1440 is 67.7 for Medium and 60.6 for High, which are playable. Ultra at 45.9 FPS is marginal, and Low at 106.3 FPS is smooth but visually compromised.

Q: What is the best setting for 1080p high-refresh-rate monitors?

A: Low settings provide the highest average FPS at 149.6 at 1920x1080. If you prefer visual quality, Medium at 103.3 FPS is a strong alternative, while High at 87.9 FPS is also viable for 144Hz displays.

Q: Can this system run Rust at 4K?

A: Technically yes, but the experience is poor. The only 4K setting that averages above 60 FPS is Low at 63.8 FPS. Medium at 38.6 FPS and High at 36.9 FPS are below acceptable levels, and Ultra at 26.4 FPS is unplayable.

Q: How does the RTX 2070 SUPER compare to its closest GPU rivals in this game?

A: The GPU’s average benchmark score of 22206 is 0.5% lower than the NVIDIA RTX A400 and 2.3% lower than the RTX 4060 Mobile, while it is 0.9% higher than the GTX TITAN Z and 2.5% higher than the AMD Radeon RX 5700. This places it in a tight competitive band.

Q: Is the Ryzen 9 7900X holding back the RTX 2070 SUPER?

A: No. The CPU ranks in the 93rd percentile versus all CPUs, while the GPU ranks in the 65th percentile. The processor’s high single-thread score (4238 in PassMark) and multi-thread capability (51406 in PassMark) far exceed what Rust requires, so the GPU is the clear limiting factor.

Q: What is the combo’s overall standing among tested systems?

A: It ranks 1033 out of 1717 combos in Rust, placing it in the lower-middle portion of the field. This reflects the GPU’s age, as the CPU is a top-tier part that could support a much stronger graphics card.
