Rust
A true test for system memory. Procedural maps can exhaust RAM quickly; 16GB is the minimum, and 32GB is recommended. CPUs with 3D V-Cache (AMD X3D) offer massive performance gains here.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, performance runs at around 45 FPS. At 1440p, performance is around 45 FPS. At 4K, frame rates range from 20 to 45 FPS.
The GeForce RTX 5090 is 251% above the recommended GPU (GeForce GTX 980) for Rust. The A4-3305M is 82% below minimum CPU requirement.
The A4-3305M sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 5090 still has headroom.
This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is clearly the CPU.
The largest gap appears at 1080p Low, where the A4-3305M reaches about 45 FPS, while the GeForce RTX 5090 still has headroom up to roughly 332 FPS.
That means the A4-3305M is hitting its performance ceiling first, leaving a 86% gap versus the GeForce RTX 5090's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is CPU-limited in 12 out of 12 cases, with 0 GPU-limited and 0 balanced results.
Overall, this is a clearly CPU-bound combination in this game.
The A4-3305M is consistently the limiting part in this game, so upgrading the CPU is more likely to deliver a larger FPS gain than upgrading the GPU.
This chart shows which upgrade is more likely to unlock more FPS in each tested setting. The lower line represents the part that reaches its limit first. When the CPU and GPU lines stay close together, the system is more balanced. When the gap widens, one component is more clearly holding the other back. Hover any setting to inspect it.
The lower line is the current limiter. The closer the two lines are, the more balanced the CPU and GPU are for this game.
Each line represents an estimated FPS ceiling for one component, rather than live usage alone.
To estimate the CPU ceiling, we pair the A4-3305M with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the GeForce RTX 5090 with Ryzen 9 9950X3D, our current CPU anchor.
The lower line indicates the current limiter, since that component reaches its FPS ceiling first. In most scenarios, that is also the part most likely to deliver the bigger performance uplift if upgraded first.
The percentage shown represents the gap between the two ceilings. In practical terms, it shows how much of the stronger component's potential is left unused because the weaker one becomes the bottleneck first.

The A4-3305M and GeForce RTX 5090 will struggle to run Rust at smooth framerates. At 1080p Ultra, you can expect around 45 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced - this ensures you're not overspending on one component that the other can't keep up with.
For Rust, upgrading the CPU would usually improve performance first. In the Performance Limiter Analysis, the A4-3305M is the side that most often caps the frame rate, while the GeForce RTX 5090 still has additional headroom in the tested presets. The main bottleneck appears on the CPU side. The largest gap shows up at 1080p Low, where the CPU reaches about 45 FPS while the GPU still has headroom up to roughly 332 FPS. Across all tested settings, the distribution is 0/12 GPU-limited, 12/12 CPU-limited, and 0/12 balanced.
Rust does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Rust requires at minimum a Core i7-3770 (CPU) and GeForce GTX 670 (GPU) with 10 GB RAM and 25 GB (SSD) storage. For the recommended experience, you need a Core i7-4790K and GeForce GTX 980 with 16 GB RAM. Your hardware falls below the minimum requirements for this game, which may result in poor performance.
These Rust FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
