Rust

The AMD Ryzen 5 3600 and AMD Radeon RX 6700 XT combination delivers a wide spread of performance in Rust, with average frame rates ranging from 29.3 FPS at 4K Ultra to 150.8 FPS at 1080p Low. The data shows a system that is heavily influenced by both resolution and quality settings, with the scaling patterns revealing a shift in bottleneck behavior as the workload changes.

Resolution Scaling

The frame rate progression across resolutions tells a clear story about which component is limiting performance in Rust. At 1920x1080, the measured FPS drops from 150.8 at Low settings to 68.4 at Ultra, a reduction of 82.4 FPS. This steep decline with increasing quality indicates that at 1080p, the GPU is being tasked more heavily as settings rise, but the CPU still has headroom to push higher frame rates when the load is light.

Moving to 2560x1440, the Low setting still produces a robust 116.1 FPS, but the gap to Ultra narrows to 48.7 FPS. The scaling from 1080p Low to 1440p Low shows a 34.7 FPS drop, which is a 23% reduction. This suggests that at lower quality presets, the resolution increase is starting to engage the GPU more significantly, though the frame rates remain high enough to indicate a balanced workload.

At 3840x2160, the picture changes dramatically. Low settings yield 66.6 FPS, which is a substantial 84.2 FPS drop from the 1080p Low result. The Ultra preset falls to 29.3 FPS, a figure that is barely playable for a survival game demanding quick reactions. The scaling pattern here — where 4K Low produces roughly the same frame rate as 1440p Ultra (66.6 vs 48.7) — indicates that the GPU is now the primary constraint. The RX 6700 XT, with its 12 GB of GDDR6 memory and 384.0 GB/s bandwidth, is being saturated by the pixel throughput required at 4K, especially with higher quality settings that increase shader complexity.

How This Combo Ranks

In the benchmark database, this CPU-GPU pairing achieves a combo rank of 960 out of 1717 tested combinations. This places it in the 56th percentile of all combos, meaning it outperforms a slight majority of systems tested in Rust. The rank reflects a mid-pack position that aligns with the component choices: a six-core CPU from 2019 paired with a GPU from 2021.

The Ryzen 5 3600 holds a percentile rank of 76 against all CPUs, with an average benchmark score of 18129. Its nearest rival, the Intel Core i5-11400, scores 18150, a delta of -0.1%, making the two processors nearly identical in synthetic tests. This near-parity suggests that the CPU is not the differentiator in most scenarios; instead, the GPU's percentile rank of 77 against all GPUs, with an average score of 33721, positions it slightly higher than the CPU relative to their respective pools.

The combo rank of 960 out of 1717 is consistent with a system where both parts are competent but not top-tier. The data implies that in Rust, the combination performs as expected for its hardware class, with no significant bottleneck skewing the results in either direction at common resolutions like 1440p.

FAQ

A: At Medium settings, the combo delivers 110.9 FPS at 1080p and 77.4 FPS at 1440p, a difference of 33.5 FPS.

Q: Does lowering settings from High to Low at 1440p improve FPS significantly?

A: Yes, at 2560x1440, Low settings produce 116.1 FPS compared to 66.7 FPS at High, an improvement of 49.4 FPS.

Measured FPS Breakdown

At 1920x1080, the combo delivers a broad range of performance. Low settings hit 150.8 FPS, Medium reaches 110.9 FPS, High drops to 94.9 FPS, and Ultra bottoms out at 68.4 FPS. The spread of 82.4 FPS between Low and Ultra indicates that the GPU is the primary driver of quality scaling at this resolution, with the CPU able to feed the graphics card adequately even at the highest preset.

At 2560x1440, the results are 116.1 FPS on Low, 77.4 FPS on Medium, 66.7 FPS on High, and 48.7 FPS on Ultra. The drop from Low to Ultra is 67.4 FPS, a slightly smaller absolute change than at 1080p, but the relative reduction is similar. The 1440p Low result is notable as it nearly matches the 1080p High result (116.1 vs 94.9), showing that resolution scaling at lower quality settings is modest.

At 3840x2160, the frame rates compress significantly. Low settings produce 66.6 FPS, Medium yields 47.3 FPS, High drops to 35.9 FPS, and Ultra falls to 29.3 FPS. The difference between Low and Ultra is 37.3 FPS, the smallest absolute gap across all resolutions. This compression indicates that at 4K, the GPU is the limiting factor regardless of quality settings, as the pixel fill rate demands overwhelm the processor.

The data shows a consistent pattern: 1080p and 1440p offer playable frame rates at all settings, with Ultra at 1440p still exceeding 45 FPS. At 4K, only Low and Medium settings exceed 45 FPS, while High and Ultra fall below 36 FPS, suggesting that 4K gaming with this combo requires careful settings management.

GPU Role

The AMD Radeon RX 6700 XT, built on the RDNA 2.0 architecture with a Navi 22 chip, operates at a base clock of 2321 MHz and a boost clock of 2581 MHz, with a game clock of 2424 MHz. These clocks, combined with 2560 shading units and 160 texture mapping units, deliver a texture rate of 413.0 GTexel/s and a pixel rate of 165.2 GPixel/s. In Rust, these specifications translate to strong performance at 1080p and 1440p, where the GPU can sustain high frame rates across most settings.

The 12 GB of GDDR6 memory on a 192-bit bus provides 384.0 GB/s of bandwidth. This capacity is sufficient for Rust's asset streaming, as evidenced by the 4K Low result of 66.6 FPS, which matches the 1440p Ultra result of 48.7 FPS. The GPU's 13.21 TFLOPS of FP32 compute and 26.43 TFLOPS of FP16 (2:1) power the shader work required by Rust's rendering, with the 40 ray tracing cores available for games that utilize them, though Rust's data does not specifically test this feature.

The GPU's percentile rank of 77 against all GPUs, with an average benchmark score of 33721, places it near the AMD Radeon RX 6800, which scores 33493 with a delta of 0.7%. This proximity in synthetic scores suggests that in Rust, the 6700 XT performs as expected for its class, with the measured FPS results showing a clear GPU bottleneck at 4K Ultra where the 29.3 FPS result indicates the card is fully saturated.

CPU Role

The AMD Ryzen 5 3600, a Zen 2 architecture processor on the 7 nm process, features 6 cores and 12 threads with a base clock of 3.60 GHz and a boost clock of 4.20 GHz. This configuration provides a solid foundation for Rust, which can utilize multiple threads for world simulation and physics. The CPU's 32 MB of shared L3 cache (with 64 KB L1 and 512 KB L2 per core) helps reduce memory latency, though the dual-channel DDR4 memory bus with 51.2 GB/s bandwidth is a potential constraint for data-heavy scenes.

Synthetic benchmarks show the CPU's capabilities: a Cinebench R23 multi-core score of 15045 and single-core score of 2124, with a PassMark multi-thread score of 17700 and single-thread score of 2562. These numbers indicate a balanced processor that can handle both multi-threaded workloads and single-threaded tasks effectively. The CPU's percentile rank of 76 against all CPUs, with an average score of 18129, places it in the upper quartile of processors, though its nearest rivals show close competition: the AMD Ryzen 5 7535HS scores 18101 (delta 0.2%) and the AMD Ryzen 5 1600 scores 18158 (delta -0.2%).

In Rust, the CPU's role is most evident at 1080p with Low settings, where the 150.8 FPS result suggests the CPU is capable of feeding the GPU with high frame rates. However, at 4K Ultra, the CPU is not the bottleneck, as the GPU's pixel throughput limits performance. The 6-core, 12-thread configuration is sufficient for Rust's demands, as evidenced by the consistent frame rates across resolutions, but the data does not show a scenario where the CPU becomes a limiting factor, even at the highest settings.
