Rust

The data for Rust with the AMD Ryzen 5 7600X and NVIDIA GeForce RTX 4090 shows a configuration that is heavily skewed towards GPU performance. The RTX 4090 is an exceptionally powerful graphics card, while the Ryzen 5 7600X is a capable mid-range processor. The measured frame rates reveal how this imbalance plays out across different resolutions and settings, indicating where the system's limits truly lie.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly demonstrates the shifting bottleneck between the CPU and GPU. At 1920x1080 with Low settings, the system achieves an average of 242.5 FPS. Moving to 2560x1440 Low drops this to 213.8 FPS, a modest reduction, but jumping to 3840x2160 Low yields 132.1 FPS. This pattern shows that at lower resolutions, the GPU has ample headroom, and the CPU is likely the limiting factor, preventing higher frame rates. The relatively small performance hit moving from 1080p to 1440p suggests the CPU is already near its limit.

The situation changes significantly at higher settings. At 1080p Ultra, the average is 138.9 FPS. At 1440p Ultra, it falls to 93.4 FPS, and at 4K Ultra, it drops to 54.7 FPS. This steeper decline indicates that as the graphical load increases, the GPU becomes the primary constraint. The difference between the Low and Ultra settings at 4K is stark: 132.1 FPS versus 54.7 FPS. This 77.4 FPS gap demonstrates that the RTX 4090 is being pushed to its limits at 4K with higher settings, while the CPU's role diminishes as resolution increases. The data suggests that for maximizing frame rates, the CPU is the bottleneck at 1080p, but at 4K, the GPU's raw power is the deciding factor.

FAQ

Q: What is the frame rate at 1440p with High settings?

A: The measured average frame rate for the AMD Ryzen 5 7600X and RTX 4090 combination at 2560x1440 with High settings is 125.3 FPS.

Q: How does the performance at 1080p Low compare to 4K Low?

A: At 1080p Low, the system achieves 242.5 FPS, while at 4K Low, it drops to 132.1 FPS. This represents a significant performance reduction of 110.4 FPS when moving to the higher resolution.

Q: Is the RTX 4090 the primary bottleneck at 4K Ultra settings?

A: Yes. The 4K Ultra average is 54.7 FPS, compared to 138.9 FPS at 1080p Ultra. The large frame rate drop with increased resolution and settings indicates that the GPU's rendering capabilities are the primary limiting factor in this scenario.

Q: What is the best performance achieved in this test set?

A: The highest average frame rate recorded is 242.5 FPS, which occurs at 1920x1080 with Low settings.

Q: Does the CPU hold back performance at 1080p?

A: The data suggests this is the case. At 1080p Low, the frame rate is 242.5 FPS. The relatively small drop to 213.8 FPS at 1440p Low, compared to the larger drop to 132.1 FPS at 4K Low, implies that the CPU is limiting performance at the lower resolution, preventing the GPU from pushing even higher frame rates.

Q: How much faster is 1080p Medium compared to 4K Medium?

A: The 1080p Medium average is 209.3 FPS, while the 4K Medium average is 85.8 FPS. This shows a 123.5 FPS difference between the two resolutions.

GPU Role

The NVIDIA GeForce RTX 4090 is a dominant force in this configuration. Its specifications are impressive: 24 GB of GDDR6X memory on a 384-bit bus provides a massive 1.01 TB/s of bandwidth. This high bandwidth is critical for high-resolution textures and complex scenes common in a survival game like Rust. The GPU's boost clock is rated at 2520 MHz, and it features 16,384 shading units, which contribute to its 82.58 TFLOPS of FP32 performance. The 128 RT cores and 512 tensor cores also provide hardware acceleration for ray tracing and DLSS, though their impact on the measured average FPS is not directly quantified in this data.

The benchmark results show the RTX 4090's raw power. It scores 38,194 in Passmark's G3D test and 9,223 in 3DMark Steel Nomad. Its percentile ranking of 91 among all GPUs confirms its high-end status. In the context of Rust, the GPU's role becomes more critical as settings and resolution increase. The frame rate data shows a clear trend: when the graphical load is light (Low settings), the GPU can render frames quickly, but the CPU may not be able to feed it data fast enough. When the load is heavy (Ultra settings at 4K), the GPU's processing power is the limiting factor, and the frame rate drops to 54.7 FPS. The transition point appears to be around 1440p with High settings, where the system balances at 125.3 FPS.

Measured FPS Breakdown

The measured data provides a complete picture of performance across common gaming resolutions and settings. At 1920x1080, the system is capable of very high frame rates. Low settings produce an average of 242.5 FPS. Medium settings see a slight decrease to 209.3 FPS. High settings yield 178.3 FPS, and Ultra settings drop to 138.9 FPS. The scaling from Low to Ultra at 1080p shows a 103.6 FPS difference, indicating that the GPU is still capable of handling the increased load, though the CPU's influence is likely present at the higher frame rates.

Moving to 2560x1440, the performance remains strong. Low settings average 213.8 FPS, which is a minor drop from 1080p Low. Medium settings average 145.6 FPS, High settings average 125.3 FPS, and Ultra settings average 93.4 FPS. The gap between Medium and High at 1440p is 20.3 FPS, while the gap between High and Ultra is 31.9 FPS. This suggests that the Ultra preset is significantly more demanding.

At 3840x2160, the RTX 4090's limits start to show. Low settings still manage a playable 132.1 FPS. Medium settings drop to 85.8 FPS, High settings to 73.2 FPS, and Ultra settings to 54.7 FPS. The difference between 1080p Low and 4K Low is 110.4 FPS, while the difference between 1080p Ultra and 4K Ultra is 84.2 FPS. This data indicates that the GPU is the definitive bottleneck at 4K, especially with higher quality settings.

How This Combo Ranks

In the database of tested combinations for Rust, this specific pairing of the AMD Ryzen 5 7600X and NVIDIA GeForce RTX 4090 ranks at position 26 out of 1,717 total combos. This places it in the top 1.5% of all tested systems, a very strong result. The high ranking is primarily driven by the RTX 4090's immense power, which is among the best available. The CPU, while not a top-tier model, provides sufficient single-threaded performance to avoid being a major hindrance at most settings.

The ranking reflects the system's overall capability to deliver high frame rates. While it may not be the absolute fastest combination, it is well ahead of the vast majority of systems. The data shows that in terms of average FPS across all tested scenarios, this combo is a high performer. Its position at rank 26 suggests that only a handful of other CPU/GPU pairings can consistently beat it in Rust, likely those with even more powerful CPUs or slightly better optimized configurations.

CPU Role

The AMD Ryzen 5 7600X is a 6-core, 12-thread processor based on the Zen 4 architecture. It has a base clock of 4.70 GHz and a boost clock of 5.30 GHz. This high clock speed is beneficial for games like Rust, which often rely on single-threaded performance. The CPU's 32 MB of shared L3 cache helps reduce memory latency, which can be important for game logic and physics. Its benchmark scores are respectable, with a Cinebench R23 multi-core score of 24,128 and a single-core score of 3,406. The Passmark single-thread score is 4,135.

The CPU's role in this system is most apparent at lower resolutions and settings. The data shows that at 1080p Low, the frame rate is 242.5 FPS. This is likely near the CPU's maximum capable frame rate in Rust. The fact that the 1080p High score is 178.3 FPS and Ultra is 138.9 FPS shows that the GPU is still the main driver of performance differences at these settings, but the CPU's ability to process the game's logic is a limiting factor at the very high frame rates achieved on Low.

The Ryzen 5 7600X's performance is competitive with its direct rivals. Its average benchmark score of 26,272 is nearly identical to the AMD Ryzen 7 PRO 6850U (26,262) and AMD Ryzen 7 7735U (26,305), showing a delta of 0% and -0.1% respectively. This indicates that in CPU-bound scenarios, the 7600X offers performance on par with these processors. In the context of Rust, this means that while it is not the absolute fastest CPU for the game, it is more than capable of supporting high frame rates, particularly when paired with an RTX 4090. The bottleneck in this system is clearly the GPU at higher settings, with the CPU only becoming a limiting factor at the lowest settings where frame rates are extremely high.
