- NVIDIA is releasing a 12GB VRAM RTX 5070 Laptop GPU variant alongside the existing 8GB model, with first partner laptops from ASUS, Lenovo, and MSI shipping in June.
- The 12GB model uses 24Gb G7 memory (3GB modules) instead of the 16Gb G7 memory (2GB modules) used in most 50-series GPUs, tapping into a supply pool that Samsung and Micron have produced more consistently at scale.
- NVIDIA cited constrained memory supply as the reason for the new variant, telling partners it provides 'an additional pool of memory' beyond the 16Gb G7 supply that currently ships with most GeForce GPUs.
- Unless NVIDIA redesigned the 5070 with a wider 192-bit bus — which seems unlikely — the 12GB variant will not access memory as quickly as the 5070 Ti, meaning more VRAM doesn't translate to 5070 Ti-level speed.
- NotebookCheck reports 12GB 5070 laptops could cost as much as 5070 Ti counterparts; for reference, a 5070 Ti-equipped Acer Predator Helios Neo 16S AI is priced up to $2,650, though new 12GB 5070s will likely ship with less RAM.
Why it matters: Laptop shoppers will see a new 12GB RTX 5070 option starting in June, but the extra VRAM likely won't deliver 5070 Ti-level performance unless NVIDIA widens the memory bus. With NotebookCheck reporting 12GB 5070 laptops could match 5070 Ti pricing — and a 5070 Ti Acer Predator Helios already at $2,650 — buyers shouldn't equate more VRAM with more speed or a lower price tag.
