GeForce RTX 3070 vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: GeForce RTX 3070 vs GeForce GTX 1660 SUPER
The GeForce RTX 3070 is dramatically faster, around 145% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the GeForce RTX 3070 is comfortable at 1440p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p. The GeForce RTX 3070 packs 5,888 CUDA cores versus 1,408 on the GeForce GTX 1660 SUPER.
Price & Value
Pricing has the GeForce GTX 1660 SUPER at $1,250 BRL, $1,250 BRL under the GeForce RTX 3070's $2,500 BRL. Because it's both faster and competitively priced, the GeForce RTX 3070 wins on performance-per-dollar by about 23%. The GeForce GTX 1660 SUPER still sits about $1,021 BRL above its $229 BRL MSRP. The GeForce RTX 3070 still sits about $2,001 BRL above its $499 BRL MSRP.
Power & Efficiency
At 125W vs 220W, the GeForce GTX 1660 SUPER is the gentler load on your system. The GeForce RTX 3070's extra power draw buys more performance per watt, not just more heat — worth it if your PSU has the headroom. Its more modern Ampere architecture on a Samsung 8nm process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 3070 carries 8GB versus 6GB on the GeForce GTX 1660 SUPER. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 3070's memory is also faster — 448 GB/s versus 336 GB/s (256-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 3070?
The GeForce RTX 3070 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce GTX 1660 SUPER if you find it at a steep discount.
