GeForce RTX 3090 vs GeForce RTX 5070 Laptop: In-Depth Breakdown
Performance: GeForce RTX 3090 vs GeForce RTX 5070 Laptop
The GeForce RTX 3090 is significantly faster, around 39% ahead of the GeForce RTX 5070 Laptop. Both cards sit in the same broad class, well suited to 1440p. The GeForce RTX 3090 packs 10,496 CUDA cores versus 5,120 on the GeForce RTX 5070 Laptop.
Price & Value
Right now the GeForce RTX 5070 Laptop starts at $1,300 GBP against $1,300 GBP for the GeForce RTX 3090. The GeForce RTX 3090 is trading below its $1,499 GBP MSRP — a genuine deal.
Power & Efficiency
The GeForce RTX 5070 Laptop draws just 125W versus 350W for the GeForce RTX 3090, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Blackwell architecture on a TSMC 4NP process is part of why it does more with each watt.
VRAM & Future-Proofing
With 24GB against 8GB, the GeForce RTX 3090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 5070 Laptop's 8GB can fall short. The GeForce RTX 3090's memory is also faster — 936 GB/s versus 448 GB/s (384-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 5070 Laptop is roughly 5 years newer than the GeForce RTX 3090 (Blackwell vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 3090 or GeForce RTX 5070 Laptop?
The GeForce RTX 3090 is the faster card by about 39%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
