Rust

The Intel Core i7-13700K paired with the AMD Radeon RX 6750 XT delivers a broadly playable Rust experience across most settings, with the data showing a clear shift in system bottleneck as resolution and graphical load increase. This combination ranks 793rd out of 1717 tested combos, placing it just above the median for Rust performance.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on the Raptor Lake architecture, built on Intel's 10 nm process. It operates with a base clock of 3.40 GHz and a boost clock of 5.40 GHz, with a 125 W TDP. The CPU's cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and a shared 30 MB L3 cache, which is substantial for a game like Rust that often involves complex world simulation and entity tracking.

In synthetic benchmarks, the i7-13700K demonstrates strong multi-threaded capability with a Cinebench R23 multicore score of 39000 and a Geekbench multicore score of 17731. Its single-thread performance is also robust, scoring 5505 in Cinebench R23 single-core and 2850 in Geekbench single-core. The CPU's percentile ranking against all processors is 93, indicating it outperforms the vast majority of CPUs in the database. Compared to its nearest rivals, the i7-13700K scores 0.1% below the Intel Core i7-13700KF, 0.3% above the AMD EPYC 4364P, and 0.4% above the Intel Core i9-12900F, placing it in a tightly contested performance tier.

The benchmark results indicate that at 1080p with Low settings, the system achieves 172 FPS, suggesting that at lower graphical loads, the CPU is capable of feeding the GPU effectively. However, the CPU's influence is more pronounced at high framerates where per-frame CPU work becomes the limiting factor. The processor's 16 cores and 24 threads provide ample headroom for Rust's background simulation tasks, even when the GPU is not fully saturated, which is evident in the relatively high framerates at 1440p Low (120.2 FPS) compared to other settings.

GPU Role

The AMD Radeon RX 6750 XT is based on the RDNA 2.0 architecture, specifically the Navi 22 chip, manufactured on TSMC's 7 nm process. It features 12 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 432.0 GB/s. The GPU's clocks are set at a base of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz, with memory running at 2250 MHz (18 Gbps effective). The card includes 2560 shading units, 160 TMUs, and 64 ROPs, along with 40 ray tracing cores, delivering 13.31 TFLOPS of FP32 compute performance.

In the context of Rust, the GPU's VRAM capacity is a significant factor. At 4K resolution with Ultra settings, the system drops to 29.4 FPS, which is well below playable thresholds. The 12 GB frame buffer is sufficient for most scenarios, but the data shows that the GPU struggles significantly at higher resolutions with increased graphical fidelity. The GPU's percentile ranking against all GPUs is 79, and its average benchmark score of 35327 places it near the AMD Radeon RX 5600M (0.2% higher), the NVIDIA GeForce RTX 5070 Ti Mobile (0.3% lower), and the AMD Radeon 880M (0.9% lower).

The performance scaling from Low to Ultra settings at 1080p shows a drop from 172 FPS to 74.5 FPS, indicating that the GPU becomes increasingly taxed as settings rise. At 4K, the gap widens dramatically, with Low settings achieving 70.9 FPS but High settings only 42.1 FPS and Ultra falling to 29.4 FPS. This pattern suggests that while the CPU is capable of maintaining high framerates, the RX 6750 XT is the primary limiter at higher resolutions and quality presets, particularly in Rust's demanding rendering environment.

Resolution Scaling

The measured FPS data reveals a consistent decline as resolution increases from 1080p to 4K, which is expected, but the magnitude of the drop varies significantly by settings. At Low settings, the system goes from 172 FPS at 1080p to 120.2 FPS at 1440p and 70.9 FPS at 4K. This represents a 30% drop from 1080p to 1440p and a 59% drop from 1080p to 4K, indicating that even at Low settings, the GPU is being pushed harder at higher resolutions, though the framerates remain playable.

At High settings, the decline is steeper: 95.6 FPS at 1080p, 69.9 FPS at 1440p, and 42.1 FPS at 4K. The drop from 1080p to 1440p is 27%, and from 1080p to 4K is 56%. This suggests that at High settings, the GPU's workload increases more rapidly with resolution, and the system becomes more GPU-bound. At Ultra settings, the framerates fall from 74.5 FPS at 1080p to 54.2 FPS at 1440p and 29.4 FPS at 4K, with a 27% drop to 1440p and a 61% drop to 4K, making 4K Ultra effectively unplayable.

The scaling pattern indicates that at 1080p and 1440p, the system is reasonably balanced, with the CPU able to keep up with the GPU's output. However, at 4K, the GPU becomes the clear limiting component, as the framerate drops are more pronounced than what would be expected from pixel count alone, particularly at higher settings. This suggests that for 4K gaming, the RX 6750 XT does not have sufficient compute or memory bandwidth to maintain high framerates in Rust, regardless of the CPU's capabilities.

How This Combo Ranks

The combination ranks 793rd out of 1717 tested combos, positioning it in the 46th percentile of all tested systems. This rank reflects a mid-tier placement, indicating that while the CPU is top-tier (93rd percentile), the GPU's more modest ranking (79th percentile) drags the overall combo down. The data shows that this pairing is not optimized for maximum performance, as the CPU is capable of driving a more powerful GPU, but it still delivers playable framerates at most settings.

Compared to other combos, the i7-13700K's nearest CPU rivals show minimal performance deltas, with the i7-13700KF being 0.1% faster and the AMD EPYC 4364P being 0.3% slower. This suggests that the CPU choice has little impact on the overall ranking relative to similarly priced alternatives. The GPU's nearest rivals also show small deltas, with the RX 5600M being 0.2% faster and the RTX 3080 being 1.3% faster, indicating that the RX 6750 XT is closely matched with its immediate competitors in raw benchmark scores.

The combo's rank of 793 suggests that there are many systems with either faster GPUs or more balanced pairings that achieve higher framerates in Rust. However, the data shows that this combo is capable of exceeding 60 FPS at 1080p High and 1440p Medium, which are common gaming targets. At 4K, the combo struggles to maintain 60 FPS even at Low settings (70.9 FPS), but falls below 60 FPS at Medium (49.9 FPS) and High (42.1 FPS), making 4K a challenging resolution for this hardware.
