Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured frame rates for Rust with the Intel Core i7-12700KF paired with the AMD Radeon RX 9070 reveal a predictable but steep decline as resolution climbs. At 1920x1080 with Low settings, the combination produces 212 FPS average. Moving to 2560x1440 Low drops that to 144.9 FPS, a 31.7% reduction. At 3840x2160 Low, the average falls to 84.3 FPS, which is 60.2% lower than the 1080p figure. This scaling pattern is typical of a setup where the GPU becomes increasingly dominant as pixel count rises.

The High preset tells a similar story. At 1080p, the average is 120.4 FPS. At 1440p, it slips to 81.4 FPS, a 32.4% drop. At 4K, the average is 51.4 FPS, which is 57.3% below the 1080p result. The Ultra preset shows the heaviest burden: 93.3 FPS at 1080p, 60.6 FPS at 1440p (a 35% reduction), and 37.1 FPS at 4K, representing a 60.2% decline from 1080p.

What does this say about the limiting component? The fact that the 1080p Low result reaches 212 FPS suggests the CPU is capable of feeding the GPU at high rates. However, the consistent percentage drops across all presets as resolution increases indicate the GPU is the primary bottleneck at higher pixel counts. The RX 9070, with its 16 GB of GDDR6 memory and 644.6 GB/s bandwidth, is a strong card, but Rust's demanding rendering at 4K clearly overwhelms it at Ultra settings, where the average dips below 40 FPS.

The data also shows that the drop from 1080p to 1440p is relatively consistent across settings, hovering around 31-35%. The drop from 1440p to 4K is more pronounced, with the Low preset falling 41.8% and the Ultra preset falling 38.8%. This suggests that while the GPU is the limiting factor at 4K, the CPU still plays a role at 1440p, especially at Low settings where the frame rate remains above 144 FPS.

Settings Recommendations — which preset gives the best experience per the measured rows

Judging solely by the measured rows, the Medium preset at 1440p offers the most balanced experience. It delivers 100.7 FPS average, which is comfortably above the 60 FPS threshold for smooth gameplay, while the visual quality is a step above Low. At 1080p, Medium hits 145.5 FPS, which is excellent for high-refresh-rate monitors. The data indicates that Medium at 1440p is the sweet spot for this combination, as it maintains a high frame rate without the steep cost of High or Ultra.

For users prioritizing maximum frame rates, Low at 1080p is the clear winner at 212 FPS, but this comes at the expense of visual fidelity. High at 1440p delivers 81.4 FPS, which is acceptable for most players but not ideal for competitive play. The Ultra preset is only viable at 1080p, where it achieves 93.3 FPS; at 1440p it drops to 60.6 FPS, and at 4K it falls to 37.1 FPS, which is likely too low for a smooth experience in a survival game where quick reactions matter.

The data suggests that Medium is the "best experience" preset because it offers a significant visual upgrade over Low while maintaining frame rates that are 66% higher than High at 1080p (145.5 vs 120.4). At 1440p, Medium is 23.7% faster than High (100.7 vs 81.4). The gap between Medium and Ultra is even larger: at 1440p, Medium is 66.2% faster than Ultra (100.7 vs 60.6). Therefore, for most players, Medium at 1440p or 1080p is the recommended choice based on the measured data.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture with the Navi 48 chip, fabricated on a 4 nm process at TSMC. It features 16 GB of GDDR6 memory on a 256-bit bus, providing 644.6 GB/s of bandwidth. The GPU's boost clock is 2520 MHz, with a game clock of 2070 MHz. These specifications translate into a pixel rate of 322.6 GPixel/s and a texture rate of 564.5 GTexel/s, with FP32 performance at 36.13 TFLOPS.

In Rust, the GPU's role is most evident at higher resolutions and settings. The data shows that at 4K Ultra, the average FPS drops to 37.1, which is 60.2% lower than the 1080p Low result of 212 FPS. This steep decline indicates that the GPU's compute capabilities are the primary constraint at 4K. The 16 GB VRAM is likely sufficient for Rust's textures, but the raw shading power of 3584 shading units is taxed heavily at 4K.

The GPU's memory bandwidth of 644.6 GB/s is a strong asset, but the measured results suggest that it is not enough to overcome the computational demands of Rust at 4K Ultra. At 1440p, the GPU performs admirably, with Medium achieving 100.7 FPS. The data indicates that the RX 9070 is a capable GPU for 1440p gaming in Rust, but 4K Ultra is beyond its comfortable range. The GPU's 79th percentile ranking among all GPUs aligns with its measured performance, showing it is a solid mid-to-high tier card, but not a top-tier 4K powerhouse.
