GeForce RTX 3070 Laptop vs GeForce GTX 1660 Laptop: In-Depth Breakdown
Performance: GeForce RTX 3070 Laptop vs GeForce GTX 1660 Laptop
The GeForce RTX 3070 Laptop is dramatically faster, around 156% ahead of the GeForce GTX 1660 Laptop. That gap is enough to move it up a tier: the GeForce RTX 3070 Laptop is comfortable at 1080p, while the GeForce GTX 1660 Laptop is better matched to entry-level 1080p. The GeForce RTX 3070 Laptop packs 5,120 CUDA cores versus 1,408 on the GeForce GTX 1660 Laptop.
Price & Value
Pricing has the GeForce GTX 1660 Laptop at $450 GBP, $140 GBP under the GeForce RTX 3070 Laptop's $590 GBP.
Power & Efficiency
At 80W vs 125W, the GeForce GTX 1660 Laptop is the gentler load on your system. The GeForce RTX 3070 Laptop'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 Laptop carries 8GB versus 6GB on the GeForce GTX 1660 Laptop. 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 Laptop's memory is also faster — 448 GB/s versus 192 GB/s (256-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 3070 Laptop is roughly 2 years newer than the GeForce GTX 1660 Laptop (Ampere vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
