GeForce RTX 4070 Laptop vs GeForce RTX 2080 Laptop: In-Depth Breakdown
Performance: GeForce RTX 4070 Laptop vs GeForce RTX 2080 Laptop
The GeForce RTX 4070 Laptop is significantly faster, around 28% ahead of the GeForce RTX 2080 Laptop. Both cards sit in the same broad class, well suited to 1080p. The GeForce RTX 4070 Laptop packs 4,608 CUDA cores versus 2,944 on the GeForce RTX 2080 Laptop.
Price & Value
Right now the GeForce RTX 4070 Laptop starts at $1,667 GBP against $2,000 GBP for the GeForce RTX 2080 Laptop.
Power & Efficiency
The GeForce RTX 4070 Laptop sips power at 115W next to the GeForce RTX 2080 Laptop's 150W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Ada Lovelace architecture on a TSMC 4N process is part of why it does more with each watt.
Memory & Bandwidth
The GeForce RTX 2080 Laptop's memory is faster — 448 GB/s versus 256 GB/s (256-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 4070 Laptop is roughly 4 years newer than the GeForce RTX 2080 Laptop (Ada Lovelace vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
