GeForce RTX 3060 8GB vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: GeForce RTX 3060 8GB vs GeForce GTX 1660 SUPER
The GeForce RTX 3060 8GB is dramatically faster, around 50% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the GeForce RTX 3060 8GB is comfortable at 1080p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p. The GeForce RTX 3060 8GB packs 3,584 CUDA cores versus 1,408 on the GeForce GTX 1660 SUPER.
Power & Efficiency
The GeForce GTX 1660 SUPER pulls less power (125W vs 170W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 3060 8GB 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 8GB against 6GB, the GeForce RTX 3060 8GB 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 GTX 1660 SUPER's memory is also faster — 336 GB/s versus 240 GB/s (192-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 3060 8GB is roughly 2 years newer than the GeForce GTX 1660 SUPER (Ampere vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1660 SUPER or GeForce RTX 3060 8GB?
The GeForce RTX 3060 8GB is the faster card by about 50%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
