GeForce RTX 3080 Laptop vs GeForce RTX 5070 Laptop: In-Depth Breakdown
Performance: GeForce RTX 3080 Laptop vs GeForce RTX 5070 Laptop
The GeForce RTX 3080 Laptop and GeForce RTX 5070 Laptop post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to 1440p gaming. The GeForce RTX 3080 Laptop packs 6,144 CUDA cores versus 5,120 on the GeForce RTX 5070 Laptop.
Price & Value
Right now the GeForce RTX 3080 Laptop starts at $1,675 CAD against $1,899 CAD for the GeForce RTX 5070 Laptop.
Power & Efficiency
The GeForce RTX 5070 Laptop sips power at 125W next to the GeForce RTX 3080 Laptop's 150W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Blackwell architecture on a TSMC 4NP process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 3080 Laptop's 16GB (vs 8GB on the GeForce RTX 5070 Laptop) gives it more room for 4K textures and memory-hungry creative or AI workloads.
Generation & Longevity
The GeForce RTX 5070 Laptop is roughly 4 years newer than the GeForce RTX 3080 Laptop (Blackwell vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
