Rust

The AMD Ryzen 5 5600G paired with the AMD Radeon RX 6600 XT delivers a playable but resolution-sensitive experience in Rust. The data shows a clear progression: at 1080p the combo is capable of high refresh rates, but 4K Ultra drops below 30 FPS. This analysis breaks down the measured results to show where the bottleneck lies and how this combination stacks against other tested hardware.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and steady, indicating that the GPU is the primary limiting factor at higher resolutions. At Low settings, the combo produces 139.6 FPS at 1920x1080, but this falls to 94 FPS at 2560x1440 and further to 54.4 FPS at 3840x2160. That is a 61% reduction in performance from 1080p to 4K at Low settings, showing how heavily the RX 6600 XT is taxed as pixel count rises.

The scaling pattern is similar across all settings. Moving from 1080p to 1440p at High settings drops the average from 77.9 FPS to 51.3 FPS, a 34% decline. The jump to 4K High brings the average down to 31.5 FPS, which is a further 39% reduction. This consistent proportional decline across settings suggests that the GPU's compute and memory bandwidth are saturated before the CPU becomes a constraint.

At Ultra settings, the resolution scaling is even more punishing. The combo starts at 61.1 FPS at 1080p, falls to 42 FPS at 1440p, and collapses to 22.4 FPS at 4K. The 4K Ultra result is below playable thresholds for most users, and the data indicates that the RX 6600 XT's 8 GB of GDDR6 memory and 256.0 GB/s bandwidth are insufficient for this game's high-resolution asset streaming. The GPU's pixel rate of 165.7 GPixel/s and texture rate of 331.4 GTexel/s are simply overwhelmed at 3840x2160 with maximum settings.

How This Combo Ranks

In Rust, this CPU-GPU combination ranks 1240 out of 1717 tested combos. This places it in the lower third of all configurations, which is noteworthy given the individual components' benchmark scores. The CPU has a percentile ranking of 78 among all processors, and the GPU has a percentile ranking of 71 among all graphics cards, yet their combined performance in this specific title is middling.

The combo's rank suggests that Rust's engine does not scale well with this particular pairing. The CPU's average benchmark score is 19983, which is nearly identical to its nearest rivals. The Intel Core i7-11600H scores 19949 (0.2% lower), the Intel Core i7-11800H scores 20024 (0.2% higher), and the AMD EPYC 7713P also scores 20024 (0.2% higher). The AMD Ryzen Threadripper PRO 5995WX scores 19928, which is 0.3% lower. This tight clustering indicates the CPU is competitive but not exceptional.

The GPU tells a similar story. Its average benchmark score is 27985, with the NVIDIA GeForce GTX 980 Ti scoring 27956 (0.1% lower) and the AMD Radeon R9 M395X scoring 27883 (0.4% lower). The NVIDIA GeForce RTX 3070 scores 28238, which is 0.9% higher, and the AMD FirePro S7150 scores 28409, which is 1.5% higher. Despite these close benchmark scores, the combo's overall rank in Rust is dragged down by the game's specific demands.

GPU Role

The Radeon RX 6600 XT is built on the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process by TSMC. It has 2048 shading units, 128 texture mapping units, and 64 ROPs, along with 32 ray tracing cores. The GPU operates with a base clock of 1968 MHz, a game clock of 2359 MHz, and a boost clock of 2589 MHz. These clocks are relatively high, but the memory configuration is the limiting factor.

The 8 GB of GDDR6 memory runs at 2000 MHz with a 16 Gbps effective speed across a 128-bit bus, yielding a bandwidth of 256.0 GB/s. In Rust, this bandwidth appears insufficient for 4K Ultra settings, where the average FPS drops to 22.4. The measured data shows that at 1080p, the GPU can push 139.6 FPS on Low, but this drops to 61.1 FPS on Ultra. The gap between Low and Ultra at 1080p is 78.5 FPS, indicating that the GPU's shading and texturing capabilities are the primary differentiator at lower resolutions.

The GPU's FP32 performance of 10.60 TFLOPS and FP16 of 21.21 TFLOPS (2:1) are respectable for this class, but Rust's draw calls and object rendering seem to rely more on raw memory throughput. The 128-bit memory bus is a known constraint, and the benchmark results confirm that higher resolutions expose this weakness.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce 139.6 FPS average, Medium produces 94.2 FPS, High produces 77.9 FPS, and Ultra produces 61.1 FPS. The 1080p Low result is the only setting where the combo exceeds 120 FPS, making it suitable for high-refresh monitors only at the lowest quality preset. The drop from Low to Medium is 45.4 FPS, while the drop from Medium to High is 16.3 FPS, and from High to Ultra is 16.8 FPS. This shows diminishing returns as settings increase, with each tier costing roughly 15-20% performance.

Moving to 2560x1440, the averages are 94 FPS at Low, 64.6 FPS at Medium, 51.3 FPS at High, and 42 FPS at Ultra. The Low setting retains a playable frame rate, but Ultra dips below 45 FPS. The gap between Low and Ultra is 52 FPS, which is a 55% reduction. This resolution is the sweet spot for this combo if the user is willing to compromise on settings, but High and Ultra both fall below the 60 FPS threshold.

At 3840x2160, the results are mostly unplayable. Low settings yield 54.4 FPS, Medium yields 37.8 FPS, High yields 31.5 FPS, and Ultra yields 22.4 FPS. Only the Low preset approaches a smooth experience, and even that is marginal. The scaling from 1440p to 4K at Low settings is a 42% drop, while at Ultra the drop is 46.7%. The data indicates that this resolution is not viable for this combo in Rust, regardless of settings.

CPU Role

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture with the Cezanne codename. It has a base clock of 3.90 GHz and a boost clock of 4.40 GHz, with a 65 W TDP. The CPU has 16 MB of L3 cache, 512 KB of L2 per core, and 64 KB of L1 per core. Its memory support is DDR4 with dual-channel configuration, yielding a bandwidth of 51.2 GB/s.

In Rust, the CPU's role is less pronounced than the GPU's, based on the resolution scaling data. The fact that FPS drops consistently as resolution increases suggests that the CPU is not the primary bottleneck at higher resolutions. However, at 1080p Low, the CPU's single-thread performance becomes more relevant. The CPU scores 872 on 3dmark single-thread, 993 on Cinebench R20 single-core, and 2365 on Cinebench R23 single-core. These scores are modest for a modern CPU, and Rust's engine is known to be single-thread bound in certain scenarios.

The CPU's multi-threaded performance is stronger, with a Cinebench R23 multicore score of 16758 and a Passmark multithread score of 19717. The 3dmark 16-thread score is 5451, and the max-thread score is 5455, indicating that the CPU scales well up to 12 threads. Despite this, the combo's rank of 1240 out of 1717 suggests that the CPU's per-core performance is not sufficient to fully feed the GPU at lower resolutions. At 1080p Low, the 139.6 FPS result may be limited by the CPU's single-thread capability rather than the GPU's raw power.
