Rust

The AMD Radeon RX 6800 XT paired with the Intel Core Ultra 9 290K Plus delivers a performance curve in Rust that is heavily dictated by resolution, with the data showing a clear transition from a CPU-bound state at 1080p to a GPU-bound one at 4K. At 1920x1080 with Low settings, the combo reaches an average of 209 FPS, which drops to 144 FPS at 2560x1440 and 85 FPS at 3840x2160, representing a 59% reduction from 1080p to 4K. This scaling pattern indicates that at lower resolutions, the 24-core processor is able to feed frames faster than the graphics card can render them, while the higher pixel counts shift the bottleneck firmly to the GPU.

Resolution Scaling

The measured FPS data reveals a predictable yet telling degradation as resolution increases across all four settings presets. At High settings, the average frame rate falls from 119 FPS at 1080p to 82 FPS at 1440p, then to 48 FPS at 4K, showing a 60% loss from the lowest to highest resolution tested. The Medium preset follows a similar trajectory, starting at 140 FPS at 1080p, dropping to 97 FPS at 1440p, and settling at 57 FPS at 4K, with the 1440p result showing a minimum of 82 FPS and a maximum of 111 FPS, while the 4K result has a tighter band of 49 to 66 FPS.

Low settings produce the highest raw numbers, with 209 FPS at 1080p, 144 FPS at 1440p, and 85 FPS at 4K, but the percentage drop from 1080p to 4K is still 59%, indicating that even at minimal graphical load, the GPU becomes the limiting factor at higher resolutions. Ultra settings push the system hardest, yielding 90 FPS at 1080p, 62 FPS at 1440p, and just 37 FPS at 4K, which is a 59% decline as well, showing that the relative performance scaling is remarkably consistent across presets.

The consistency of this ~60% drop across all settings suggests that the RX 6800 XT's 16 GB of GDDR6 memory and 512.0 GB/s bandwidth are sufficient for Rust's data demands, but the raw compute throughput of 20.74 TFLOPS begins to struggle as pixel count rises. At 1080p, the gap between Low and Ultra is 119 FPS (209 vs 90), while at 4K, that gap narrows to 48 FPS (85 vs 37), further confirming that resolution, not settings, drives the performance delta at higher pixel densities.

GPU Role

The Radeon RX 6800 XT, built on the RDNA 2.0 architecture with a Navi 21 chip, brings 16 GB of GDDR6 memory across a 256-bit bus, delivering 512.0 GB/s of bandwidth. The GPU's boost clock of 2250 MHz and game clock of 2015 MHz, with a base clock of 1825 MHz, provide the compute foundation for these results. With 4608 shading units, 288 TMUs, and 128 ROPs, the card produces a pixel rate of 288.0 GPixel/s and a texture rate of 648.0 GTexel/s, which are the key spec figures that correlate with the observed frame rates.

The GPU's 72 ray accelerators (RT cores) and 12 Ultimate API support are present in the specs, though Rust's rasterization-heavy workload means these features see minimal direct impact on the measured averages. The 4K Low result of 85 FPS shows that even with reduced graphical fidelity, the card's compute capacity of 20.74 TFLOPS FP32 is the ceiling, as the 1440p Low result of 144 FPS is over 40% higher. The 4K Medium result of 57 FPS with a minimum of 49 FPS indicates that the card's memory subsystem and bandwidth are handling the increased texture loads without stutter, but the average frame rate drops predictably as the shading units take on more work.

Comparing to its nearest rivals, the RX 6800 XT's average benchmark score of 48477 places it 1.5% ahead of the NVIDIA RTX A1000 Mobile and 2.5% behind the Intel Arc A550M, while the GeForce RTX 5070 Ti and Radeon RX Vega 64 both sit 3% higher. These marginal deltas in synthetic benchmarks do not translate directly to Rust's real-world results, where the 16 GB frame buffer and 512.0 GB/s bandwidth prove adequate for all tested presets, from Low to Ultra, without hitting memory capacity limits.
