Rust

The Intel Core i5-12600KF paired with the AMD Radeon RX 6700 XT delivers a solid 1080p and 1440p experience in Rust, but the data reveals a sharp performance cliff at 4K. This combination ranks in the 48th percentile of tested combos, indicating a balanced pairing that is more constrained by the GPU at higher resolutions than by the processor.

Resolution Scaling

The measured FPS data shows a clear and predictable drop as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate falls from 165 FPS at 1080p to 114 FPS at 1440p, a 31% reduction, and then to 67 FPS at 4K, a further 41% drop. This pattern indicates that while the CPU has ample headroom at lower resolutions, the GPU becomes the primary bottleneck as pixel count rises.

At High settings, the scaling is even more pronounced: 93 FPS at 1080p drops to 64 FPS at 1440p (a 31% decrease) and then plummets to 38 FPS at 4K (a 41% decrease from 1440p). The 4K High result of 38 FPS is below the threshold for smooth gameplay, suggesting that this combo is not suitable for 4K gaming at higher quality presets without significant compromises.

The Ultra settings tell a similar story, with 71 FPS at 1080p falling to 49 FPS at 1440p and then to 29 FPS at 4K. The gap between 1080p and 4K Ultra is 42 FPS, representing a 59% drop in performance. This steep decline at 4K across all settings strongly indicates that the RX 6700 XT’s 12 GB frame buffer and 384.0 GB/s memory bandwidth are insufficient to handle the demands of Rust’s expansive environments at that resolution.

Interestingly, the Medium settings provide the only complete min/max data across all resolutions. At 1080p Medium, the average is 111 FPS with a minimum of 94 FPS, while at 1440p Medium, the average drops to 76 FPS with a minimum of 65 FPS. At 4K Medium, the average is 45 FPS with a minimum of 38 FPS and a maximum of 52 FPS. The minimum FPS values at 4K Medium (38 FPS) align closely with the average at 4K High (38 FPS), suggesting that the GPU is consistently hitting its performance ceiling.

GPU Role

The AMD Radeon RX 6700 XT, built on the RDNA 2.0 architecture with the Navi 22 chip, features a base clock of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz. These clock speeds, combined with 2560 shading units, 160 texture mapping units, and 64 render output units, allow the card to achieve a pixel rate of 165.2 GPixel/s and a texture rate of 413.0 GTexel/s. The FP32 performance is rated at 13.21 TFLOPS.

In Rust, the GPU’s role becomes increasingly dominant as resolution increases. At 1080p Low, the 165 FPS average suggests that the CPU is still able to feed the GPU efficiently, but even here, the RX 6700 XT is nearing its limits. The 12 GB of GDDR6 memory on a 192-bit bus provides 384.0 GB/s of bandwidth, which is adequate for 1080p and 1440p but becomes a constraint at 4K, where the larger textures and draw distances require more memory throughput.

The GPU’s performance percentile of 72 against all GPUs places it in the upper mid-range, and its average benchmark score of 27425 is nearly identical to the NVIDIA GeForce RTX 3090, which scores 27565 with a deltaPct of -0.5. This comparison is noteworthy because the RTX 3090 is a much larger and more expensive card, yet the RX 6700 XT matches it in synthetic benchmarks. However, in Rust’s real-world scenarios, the 4K results show that the RX 6700 XT struggles, indicating that the game’s engine is particularly demanding on memory bandwidth and raw fill rate.

The card’s DirectX 12 Ultimate support and Vulkan 1.4 API compatibility are relevant for Rust, which has historically favored certain API implementations. The PassMark DirectX 12 score of 77 and DirectX 11 score of 173 suggest that the card performs better in older APIs, which may explain why Rust’s performance is not as strong as the synthetic benchmarks would imply.

How This Combo Ranks

The Intel Core i5-12600KF + AMD Radeon RX 6700 XT combination holds a rank of 1946 out of 3723 tested combos in Rust. This places it almost exactly in the middle of the database, at the 48th percentile. This ranking indicates that while the pairing is competent, it is not exceptional for this specific title, and many other combinations deliver higher frame rates.

The CPU’s percentile of 79 against all CPUs is notably higher than the combo’s overall ranking, suggesting that the processor is not the limiting factor. The i5-12600KF’s average benchmark score of 27799 is nearly identical to the AMD Ryzen 7 5800X3D, which scores 27896 with a deltaPct of -0.3. This means the Intel chip is essentially on par with one of AMD’s most respected gaming processors, yet the combo rank in Rust is middling.

This discrepancy points directly to the GPU as the bottleneck. The RX 6700 XT’s percentile of 72 against all GPUs is lower than the CPU’s percentile, and in Rust specifically, the GPU’s performance is insufficient to boost the combo into the upper ranks. The data shows that at 1080p, where the CPU has more influence, the combo achieves 165 FPS on Low, which is respectable. But at 4K, where the GPU dominates, the frame rates drop to unplayable levels, dragging the overall rank down.

Compared to other combos in the database, this pairing is best suited for 1440p gaming, where it delivers 114 FPS on Low and 64 FPS on High. At these settings, the combo ranks competitively, but the 4K results are poor enough to prevent a higher overall standing. The rank of 1946 out of 3723 suggests that enthusiasts seeking maximum performance in Rust should look at combinations with more powerful GPUs, while those targeting 1080p or 1440p will find this combo adequate.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of how this combo performs across three resolutions and four quality presets.

At 1920x1080, the lowest resolution tested, the combo delivers strong performance. On Low settings, the average FPS is 165, which is exceptionally smooth and well above the refresh rate of most monitors. Medium settings yield an average of 111 FPS with a minimum of 94 FPS and a maximum of 127 FPS, indicating good frame pacing. High settings reduce the average to 93 FPS, while Ultra settings drop it to 71 FPS. The scaling from Low to Ultra at 1080p shows a 57% reduction in performance, highlighting the significant impact of quality presets on this resolution.

At 2560x1440, the performance remains playable but with noticeable reductions. Low settings produce an average of 114 FPS, which is still smooth for competitive play. Medium settings average 76 FPS with a minimum of 65 FPS and a maximum of 88 FPS, providing a good balance between visual fidelity and smoothness. High settings average 64 FPS, which is adequate for most players, while Ultra settings drop to 49 FPS, which may feel less responsive in fast-paced scenarios. The transition from 1080p to 1440p at each setting results in a 31% to 35% decrease in average FPS, consistent with the increased pixel count.

At 3840x2160, the combo struggles to maintain playable frame rates. Low settings average 67 FPS, which is the only 4K preset that approaches acceptability, though it still represents a 41% drop from 1440p Low. Medium settings average 45 FPS with a minimum of 38 FPS and a maximum of 52 FPS, indicating that frame times can spike to uncomfortable levels. High settings average 38 FPS, which is below the 40 FPS threshold for smooth gameplay. Ultra settings average 29 FPS, making the game effectively unplayable at this quality. The 4K results clearly demonstrate that this GPU is not designed for ultra-high-definition gaming in Rust.

CPU Role

The Intel Core i5-12600KF is a 10-core, 16-thread processor based on the Alder Lake architecture, manufactured on Intel’s 10 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.90 GHz, with 20 MB of shared L3 cache. The CPU supports DDR4 and DDR5 memory in a dual-channel configuration, and its 20 PCIe Gen 4 lanes provide ample bandwidth for the RX 6700 XT.

In Rust, the CPU’s role is primarily to handle game logic, physics, and draw calls, which are heavily multithreaded. The i5-12600KF’s benchmark scores reflect its strong performance: a Cinebench R23 multicore score of 23391 and a single-core score of 3302. Its PassMark multithread score is 27575, and its single-thread score is 3925. These figures place the CPU in the 79th percentile against all CPUs, indicating it is a high-performing processor.

The data from the measured FPS shows that the CPU is not the bottleneck in this combo. At 1080p Low, the 165 FPS average is likely near the GPU’s maximum output, as increasing resolution to 1440p Low only reduces the FPS to 114, a 31% drop that aligns with the GPU’s rendering load. If the CPU were the limiting factor, the FPS would remain more consistent across resolutions. Instead, the FPS scales inversely with resolution, confirming that the GPU is the primary constraint.

The CPU’s 16 threads are well-suited for Rust’s multithreaded nature, and the high boost clock of 4.90 GHz ensures strong single-threaded performance for tasks that cannot be parallelized. The L3 cache of 20 MB is generous and helps reduce memory latency, which is beneficial for the large, persistent world of Rust. While the CPU’s average benchmark score of 27799 is nearly identical to the Ryzen 7 5800X3D, the latter is often favored for gaming due to its 3D V-Cache, but the data here shows no significant advantage in this specific test scenario.

Overall, the i5-12600KF provides a robust foundation for this combo, ensuring that the GPU is fully utilized at 1080p and 1440p. The CPU’s performance headroom means that users could potentially upgrade to a more powerful GPU in the future without needing to replace the processor, as the 10-core, 16-thread configuration is likely to remain relevant for several years.
