Rust

The AMD Ryzen 5 3600 and AMD Radeon RX 6750 XT combination in Rust delivers a solid 1080p and 1440p experience, but the data shows a sharp falloff at 4K. This pairing sits at rank 853 out of 1717 tested combos, placing it in the upper-middle tier of all hardware pairings for this title. The measured frames per second reveal a system that is well-balanced at lower resolutions but increasingly GPU-limited as pixel count rises.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor based on the Zen 2 architecture, built on a 7 nm process at TSMC. It runs with a base clock of 3.60 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. The CPU's cache layout includes 64 KB of L1 per core, 512 KB of L2 per core, and a shared 32 MB L3 cache. It supports DDR4 memory on a dual-channel bus, delivering 51.2 GB/s of bandwidth. The processor sits on the AMD Socket AM4 platform and uses PCIe Gen 4 with 16 lanes from the CPU.

In Rust, the CPU's multi-threaded capacity matters significantly. The 3DMark 16-thread score of 4605 and the max-threads score of 4603 show near-linear scaling from 8 threads (3844) to 16 threads, indicating that the extra threads are useful for this game's simulation and entity-processing loads. The single-thread score of 696 is modest, but Rust's workload appears to distribute well across cores. The Cinebench R23 multicore score of 15045 and single-core score of 2124 place this chip in a competitive position. Its average benchmark score of 18129 puts it at the 76th percentile of all CPUs, and its nearest rival, the Intel Core i5-11400, scores 18150 — a delta of only -0.1%, making them effectively identical in overall compute capability.

The practical implication for Rust is that the Ryzen 5 3600 provides enough headroom to avoid bottlenecking the GPU at 1080p. The 1080p Low result of 149.8 FPS is the highest measured across all resolutions and settings, suggesting the CPU can feed frames well above typical 144 Hz refresh rates when the GPU is not the constraint. However, the 2-thread score of 1361 and 4-thread score of 2579 indicate that if Rust were poorly optimized for multi-threading, the system would struggle — but the data shows it does not.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, fabricated on a 7 nm process at TSMC. It features 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The GPU operates with a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. Its memory runs at 2250 MHz, which translates to 18 Gbps effective. The card includes 2560 shading units, 160 texture mapping units, and 64 raster operation units, along with 40 ray tracing cores. It achieves a pixel rate of 166.4 GPixel/s and a texture rate of 416.0 GTexel/s, with FP32 performance of 13.31 TFLOPS.

For Rust, the GPU's 12 GB VRAM is more than sufficient for the game's textures and draw distances, even at 4K Ultra. The GPU's average benchmark score is 35327, placing it at the 79th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 5600M, scores 35264 (a delta of 0.2%), while the NVIDIA GeForce RTX 3080 scores 35787 (a delta of -1.3%). This shows the RX 6750 XT is competitive with much larger cards in overall compute, though the measured FPS in Rust tells a more nuanced story about memory bandwidth and rasterization limits.

The GPU's role becomes the dominant factor at 4K. At 4K Ultra, the system drops to 32.1 FPS, which is unplayable for a competitive survival game. Even at 4K Low, the card only manages 70.3 FPS. The gap between 1080p and 4K results is stark, indicating that the RX 6750 XT's 432.0 GB/s of bandwidth is a limiting factor at higher resolutions where fill rate demands spike.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear scaling pattern. At 1080p Low, the system produces 149.8 FPS. Moving to 1440p Low, that drops to 117.1 FPS — a 21.8% reduction. At 4K Low, it falls further to 70.3 FPS, a 53.1% drop from the 1080p Low result. This pattern holds across settings. At 1080p High, the system achieves 100.4 FPS; at 1440p High, it drops to 69 FPS (a 31.3% reduction); and at 4K High, it falls to 42.2 FPS (a 58% reduction from 1080p High).

The scaling from 1080p to 1440p is roughly linear with pixel count (2.25x pixels yields a 21-31% FPS drop), which suggests a balanced load. However, the jump from 1440p to 4K (2.25x more pixels again) produces a much steeper drop — from 117.1 to 70.3 FPS at Low settings (a 40% drop) and from 69 to 42.2 FPS at High settings (a 38.8% drop). This disproportionate loss indicates the GPU is hitting a bandwidth or memory-interface ceiling at 4K, not a raw compute limit.

The CPU's influence is visible at 1080p. The 149.8 FPS Low result is likely near the CPU's practical ceiling for Rust's simulation thread, as 1080p Ultra only reaches 77.2 FPS — a 48.5% drop from Low, which is a much larger settings penalty than at 1440p (where Ultra drops to 50 from Low's 117.1, a 57.3% drop). This inverted relationship shows that at 1080p, the CPU can still push frames when the GPU is under-utilized, but the GPU becomes the hard limit at 4K.

A: Yes. The measured data shows 1080p Low at 149.8 FPS, 1080p Medium at 113.7 FPS, and 1080p High at 100.4 FPS. Even 1080p Ultra holds 77.2 FPS, which is above the 60 FPS threshold for smooth play.

Q: Can this system handle 1440p at high refresh rates?

A: Partially. At 1440p Low, it hits 117.1 FPS, and at 1440p Medium, it reaches 83.1 FPS. However, 1440p High drops to 69 FPS, and 1440p Ultra falls to 50 FPS. For competitive play, Low or Medium settings are recommended to stay above 100 FPS.

Q: What is the best resolution for this combo in Rust?

A: The data indicates 1440p with Medium settings (83.1 FPS) provides the best balance of visual quality and performance. 1080p is smoother but the visual fidelity is lower, while 4K is only playable at Low settings (70.3 FPS) with major compromises.

Q: How does the CPU compare to its nearest rival in overall performance?

A: The Ryzen 5 3600 has an average benchmark score of 18129. Its closest rival, the Intel Core i5-11400, scores 18150, a delta of -0.1%. They are statistically identical in compute performance, meaning either CPU would deliver similar results in Rust.

Q: How does the GPU compare to the RTX 3080 in this context?

A: The RX 6750 XT has an average score of 35327, while the RTX 3080 scores 35787, a delta of -1.3%. Despite the RTX 3080 having a nominal advantage, the measured Rust FPS data shows the RX 6750 XT is competitive at 1080p, where the CPU is more relevant.

Q: Is 4K gaming viable with this hardware?

A: Only in limited situations. The 4K High result of 42.2 FPS is below acceptable playability, but 4K Low at 70.3 FPS is playable if visual fidelity is sacrificed. 4K Medium (50.1 FPS) sits right at the edge of playability, while 4K Ultra (32.1 FPS) is not recommended.

Settings Recommendations

The measured FPS rows provide clear guidance for settings selection. For 1080p users, Medium (113.7 FPS) offers a significant improvement over High (100.4 FPS) with only a modest visual downgrade, while Ultra (77.2 FPS) is only worth it if you have a 75 Hz monitor. For 1440p, Medium (83.1 FPS) is the sweet spot — it provides a 20.4% FPS improvement over High (69 FPS) while maintaining most visual quality. Low (117.1 FPS) is the competitive choice for maximum frame rate.

For 4K, the data shows that Low (70.3 FPS) is the only setting that stays above 60 FPS, and even then, it is borderline. Medium (50.1 FPS) is playable but noticeably less smooth. High (42.2 FPS) and Ultra (32.1 FPS) are not recommended for any scenario. The optimal strategy across all resolutions is to favor Medium settings, as the performance gain from dropping to Low is substantial at 1440p (a 40.9% increase from Medium) but less impactful at 1080p (a 31.7% increase from Medium).

Measured FPS Breakdown

The complete measured FPS table from the data is as follows:

1920x1080:

• Low: 149.8 FPS
• Medium: 113.7 FPS
• High: 100.4 FPS
• Ultra: 77.2 FPS

2560x1440:

• Low: 117.1 FPS
• Medium: 83.1 FPS
• High: 69 FPS
• Ultra: 50 FPS

3840x2160:

• Low: 70.3 FPS
• Medium: 50.1 FPS
• High: 42.2 FPS
• Ultra: 32.1 FPS

The performance hierarchy is consistent: Low always yields the highest frame rate, and Ultra always the lowest. The gap between Low and Ultra widens with resolution — at 1080p, the difference is 72.6 FPS (149.8 minus 77.2); at 1440p, it is 67.1 FPS; and at 4K, it shrinks to 38.2 FPS. This compression at 4K confirms that the GPU is hitting a hard ceiling regardless of settings, as the pixel fill rate becomes the dominant constraint. The 1080p Low result of 149.8 FPS is the single highest measured value, indicating that the Ryzen 5 3600 can drive this GPU to near-maximum output when the resolution is low enough.
