# Rust with AMD Ryzen 5 4600G + NVIDIA GeForce GTX 1660 SUPER

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce GTX 1660 SUPER is a balanced mid-range combination, landing at rank 1489 out of 1717 tested combos in Rust. This places it in the lower-middle tier of tested systems, with the CPU holding a 75th percentile standing against all processors and the GPU sitting at the 55th percentile against all GPUs. The data shows a system that can handle Rust at 1080p with reasonable settings, but struggles significantly as resolution climbs.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals where the bottleneck lives. At Low settings, the system delivers 104.2 FPS at 1920x1080, drops to 75.3 FPS at 2560x1440 (a 28% reduction), and falls to 42.5 FPS at 3840x2160 (a 59% reduction from 1080p). This pattern indicates the GPU is the primary limiting factor at higher resolutions, as the pixel throughput demand outpaces what the GTX 1660 SUPER can deliver.

At Medium settings, the scaling is similar but with a steeper cliff: 71.4 FPS at 1080p, 46.7 FPS at 1440p, and 29.9 FPS at 4K. The 4K figure represents a 58% loss from 1080p Medium. High settings show 60.8 FPS at 1080p, 43.7 FPS at 1440p, and 26.4 FPS at 4K — the 1440p result is only 28% below 1080p, but 4K falls another 40% from the 1440p mark. Ultra settings are the most punishing: 48.9 FPS at 1080p, 30.1 FPS at 1440p, and 20.4 FPS at 4K.

The 1080p-to-1440p transitions are relatively gentle (15-28% drops), but 1440p-to-4K transitions are brutal (38-44% drops) across all settings. This is classic VRAM and memory bandwidth pressure — the GTX 1660 SUPER has 6 GB of GDDR6 on a 192-bit bus with 336.0 GB/s bandwidth, which gets saturated quickly as pixel count rises. The Ryzen 5 4600G's dual-channel DDR4 memory bandwidth of 51.2 GB/s is not the constraint here; the GPU's fill rate limitations show up clearly at 4K.

Settings Recommendations

The measured rows show a clear sweet spot at 1080p Medium, which delivers 71.4 FPS. That is comfortably above the 60 FPS threshold for smooth play and leaves headroom for the island's notorious performance dips during base building or radtown fights. Low settings at 1080p hit 104.2 FPS, which is ideal for competitive play or for users with 144 Hz monitors, but the visual fidelity loss is substantial.

High settings at 1080p produce 60.8 FPS — playable, but with no margin for error. Given that Rust's worst-case moments can drop frame rates by 20-30%, the High preset at 1080p is risky for consistent smoothness. Ultra at 1080p yields 48.9 FPS, which is below the 60 FPS target and not recommended for this combination.

At 1440p, Low settings are the only viable option, producing 75.3 FPS. Medium at 1440p drops to 46.7 FPS, which is borderline for a survival game where reaction time matters. High at 1440p (43.7 FPS) and Ultra at 1440p (30.1 FPS) are both below playable thresholds for most users. At 4K, every setting is below 42.5 FPS, with Ultra hitting just 20.4 FPS — this combination is not suited for 4K gaming in Rust.

The data suggests the best experience is 1080p Medium — it balances visual quality with performance headroom. For players who prioritize frame rate above all, 1080p Low at 104.2 FPS is the safer choice, while 1440p users should stick to Low.

GPU Role

The GTX 1660 SUPER's specifications explain its behavior in Rust. It operates at a base clock of 1530 MHz and boost clock of 1785 MHz, with 1408 shading units, 88 texture mapping units, and 48 render output units. The memory runs at 1750 MHz (14 Gbps effective) across a 192-bit bus, yielding 336.0 GB/s of bandwidth. The 6 GB GDDR6 frame buffer is the critical constraint at high resolutions and settings.

The GPU's pixel rate of 85.68 GPixel/s and texture rate of 157.1 GTexel/s are the hardware limits that show up in the 4K results. At 3840x2160, the GPU must push 8.3 million pixels per frame, and the fill rate simply cannot keep up with the draw calls and texture sampling Rust demands. The FP32 throughput of 5.027 TFLOPS is modest by modern standards, which explains why Ultra settings at any resolution above 1080p fall below 50 FPS.

The GPU's benchmark percentile of 55th against all GPUs, with an average benchmark score of 14286, places it just behind the AMD Radeon RX Vega 11 (which scores 14314, a -0.2% delta) and AMD Radeon RX 5500 XT (14389, -0.7% delta). This is a GPU that was competitive at launch but is now showing its age in a demanding title like Rust. The 125 W TDP and 300 W suggested PSU indicate this is not a power-hungry card, but its compute resources are simply insufficient for high-resolution gaming.

How This Combo Ranks

The combination ranks 1489 out of 1717 tested combos in Rust, placing it in the 13th percentile of tested systems. This is a low ranking, but it needs context: the combo is built around a CPU with integrated graphics (the Radeon Vega 7) that was never intended for gaming, paired with a GPU that is now end-of-life. The CPU's benchmark scores show a strong multi-threaded performer for its class — Cinebench R23 multicore of 13593 and Passmark multithread of 15992 — but its single-thread scores (Cinebench R23 single-core 1919, Geekbench single-core 1575) are modest. Rust is known to be CPU-heavy in certain areas, but the data shows the GPU is the limiting factor here.

The CPU's nearest rivals in benchmark scores include the AMD Ryzen 3 PRO 5355GE (17482 score, 0% delta), Intel Core i5-12450H (17475, 0.1% delta), and Intel Core i3-14100T (17636, -0.8% delta). The 4600G's average benchmark score of 17489 is effectively tied with these processors, meaning the CPU is not the weak link in this pairing. The GPU, however, sits in a cluster with the RX Vega 11 (-0.2% delta) and RX 5500 XT (-0.7% delta), all within a couple of points of each other — the GTX 1660 SUPER's 14286 average score is not meaningfully better than integrated graphics solutions in raw compute.

This rank of 1489 out of 1717 suggests that many other combinations deliver better Rust performance. The combination is workable for 1080p Medium, but it is far from competitive in the broader benchmark database.

FAQ

Q: Can this combo run Rust at 60 FPS at 1080p?

A: Yes, at Low settings it hits 104.2 FPS at 1920x1080, and at Medium it reaches 71.4 FPS. High settings produce 60.8 FPS, which is just above the 60 FPS target but with little headroom.

Q: What is the best resolution for this combination?

A: 1920x1080 is the only resolution where Medium and High settings remain playable. At 2560x1440, only Low settings (75.3 FPS) stay above 60 FPS, and at 3840x2160 the best result is 42.5 FPS on Low.

Q: Is the Ryzen 5 4600G holding back the GTX 1660 SUPER?

A: No. The CPU's average benchmark score of 17489 is within 0.8% of rivals like the Intel Core i3-14100T and 0.1% of the Intel Core i5-12450H. The GPU's 55th percentile ranking and the steep FPS drops at 4K indicate the GPU is the primary bottleneck.

Q: How does the GTX 1660 SUPER compare to its nearest rivals?

A: The GTX 1660 SUPER's average benchmark score is 14286. The AMD Radeon RX Vega 11 scores 14314 (-0.2% delta), Intel Iris Xe MAX Graphics scores 14315 (-0.2% delta), and AMD Radeon RX 5500 XT scores 14389 (-0.7% delta). These are effectively equivalent in compute.

Q: Is 4K gaming possible with this setup?

A: No. The best 4K result is 42.5 FPS at Low settings, with Ultra at 3840x2160 producing just 20.4 FPS. The 6 GB VRAM and 336.0 GB/s bandwidth are insufficient for 4K in Rust.

Q: Should I use Ultra settings at 1080p?

A: The data shows 48.9 FPS at 1080p Ultra, which is below 60 FPS and likely to feel stuttery in Rust's demanding moments. Medium at 71.4 FPS is the recommended ceiling for consistent smoothness.

Measured FPS Breakdown

1920x1080:

• Low: 104.2 FPS average
• Medium: 71.4 FPS average
• High: 60.8 FPS average
• Ultra: 48.9 FPS average

2560x1440:

• Low: 75.3 FPS average
• Medium: 46.7 FPS average
• High: 43.7 FPS average
• Ultra: 30.1 FPS average

3840x2160:

• Low: 42.5 FPS average
• Medium: 29.9 FPS average
• High: 26.4 FPS average
• Ultra: 20.4 FPS average

The data shows a consistent pattern: each settings tier at a given resolution costs roughly 20-30% of the frame rate. Moving from Low to Ultra at 1080p drops from 104.2 to 48.9 FPS (a 53% loss), while at 1440p the same transition costs 60% (75.3 to 30.1 FPS). At 4K, the Low-to-Ultra gap narrows to 52% (42.5 to 20.4 FPS) because the GPU is already saturated at Low settings. This saturation point is critical — once the GPU is fully utilized, raising settings has diminishing impact on FPS relative to the resolution cost.

For users seeking the best measured experience, 1080p Low offers the highest frame rate at 104.2 FPS, but 1080p Medium at 71.4 FPS provides the best balance between visual quality and smoothness. The system is not viable beyond 1440p Low, and even that setting requires accepting occasional dips below 60 FPS in heavy scenes. This is a capable 1080p gaming machine for Rust, but nothing more.
