NVIDIA launches RTX 5070 12GB laptop
- Nvidia on Tuesday added a 12GB GeForce RTX 5070 Laptop GPU, expanding its Blackwell mobile lineup with a higher-memory option alongside the existing 8GB model. - The new version uses 24Gb, or 3GB, GDDR7 chips on the same 128-bit bus, lifting capacity 50% without changing core counts. - The move follows months of laptop listings showing 12GB variants before Nvidia made them official.

A graphics chip’s memory is its working space, and Nvidia has now expanded that space on the GeForce RTX 5070 Laptop GPU from 8GB to 12GB. (techpowerup.com) Nvidia made the new configuration official on Tuesday, April 28, 2026, saying the 12GB version will ship alongside the existing 8GB GeForce RTX 5070 Laptop GPU. (techpowerup.com) The extra capacity comes from 24Gb GDDR7 memory modules, which equal 3GB per chip, instead of the 16Gb, or 2GB, modules used in most current GeForce parts. (techpowerup.com) Nvidia said demand for GeForce RTX graphics remains strong and memory supply is constrained, so the 12GB configuration gives laptop makers access to an additional pool of GDDR7 memory. (techpowerup.com) The company’s laptop comparison page now lists the GeForce RTX 5070 Laptop GPU with 4,608 CUDA cores, 798 AI TOPS, a 50W to 100W power range, and an 8GB GDDR7 standard memory configuration. The 12GB model adds capacity, not a new tier above the 5070 name. (nvidia.com) That matters because game textures, frame generation, and creator workloads all compete for the same memory pool, and 8GB has become a visible limit in newer PC releases. The Verge described Nvidia’s new laptop SKU as its first clear response to the memory squeeze in this part of the lineup. (theverge.com) The change appears to keep the same 128-bit memory interface, which suggests Nvidia solved the capacity problem with denser chips rather than a wider bus or a different GPU die. (techpowerup.com) (notebookcheck.net) Laptop makers had been signaling this move for weeks. Lenovo listings spotted in March showed several 2026 notebooks with GeForce RTX 5070 Laptop GPUs carrying 12GB of GDDR7. (tweaktown.com) (videocardz.com) For buyers, the immediate effect is simple: RTX 5070 laptops will start appearing in two memory versions, and the fine print on the spec sheet now matters more than the badge on the lid.
