Performance: GeForce RTX 4090 Laptop vs GeForce RTX 3070 Ti Laptop
The GeForce RTX 4090 Laptop is dramatically faster, around 54% ahead of the GeForce RTX 3070 Ti Laptop. Both cards sit in the same broad class, well suited to 1440p. The GeForce RTX 4090 Laptop packs 9,728 CUDA cores versus 5,888 on the GeForce RTX 3070 Ti Laptop.
Price & Value
Right now the GeForce RTX 3070 Ti Laptop starts at $1,596 GBP against $3,800 GBP for the GeForce RTX 4090 Laptop.
Power & Efficiency
The GeForce RTX 3070 Ti Laptop is the lighter draw at 125W against the GeForce RTX 4090 Laptop's 150W, making it the easier card to power and cool. The GeForce RTX 4090 Laptop draws more in absolute terms but squeezes out more performance per watt, so budget for a beefier PSU if you go that route. Its more modern Ada Lovelace architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 4090 Laptop's 16GB (vs 8GB on the GeForce RTX 3070 Ti Laptop) gives it more room for 4K textures and memory-hungry creative or AI workloads. The GeForce RTX 4090 Laptop's memory is also faster — 576 GB/s versus 448 GB/s — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce RTX 3070 Ti Laptop or GeForce RTX 4090 Laptop?
