GeForce RTX 3080 vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: GeForce RTX 3080 vs GeForce GTX 1660 SUPER
The GeForce RTX 3080 is dramatically faster, around 218% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the GeForce RTX 3080 is comfortable at 1440p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p. The GeForce RTX 3080 packs 8,704 CUDA cores versus 1,408 on the GeForce GTX 1660 SUPER.
Price & Value
Right now the GeForce GTX 1660 SUPER starts at $157 BRL against $4,875 BRL for the GeForce RTX 3080. Despite being slower, the GeForce GTX 1660 SUPER offers the better performance-per-dollar (~878% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 SUPER is trading below its $229 BRL MSRP — a genuine deal. The GeForce RTX 3080 still sits about $4,176 BRL above its $699 BRL MSRP.
Power & Efficiency
The GeForce GTX 1660 SUPER pulls less power (125W vs 320W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 3080 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern Ampere architecture on a Samsung 8nm process is part of why it does more with each watt.
VRAM & Future-Proofing
With 10GB against 6GB, the GeForce RTX 3080 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660 SUPER's 6GB can fall short. The GeForce RTX 3080's memory is also faster — 760 GB/s versus 336 GB/s (320-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce GTX 1660 SUPER or GeForce RTX 3080?
Choose the GeForce RTX 3080 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 SUPER stretches your money further for only slightly lower performance.
