Nvidia quietly launches 12GB RTX 5070 laptop GPU — midrange mobile gaming gets more VRAM amid the RAMpocalypse
Nvidia has quietly launched a 12GB version of the RTX 5070 laptop GPU, offering 50% more VRAM than the 8GB model while maintaining the same memory bandwidth. The new GPU uses 3GB GDDR7 memory modules on a 128-bit interface, aligning with current supply constraints. It slots between the 8GB RTX 5070 and the 12GB RTX 5070 Ti in the mobile lineup. This move provides better performance for AAA gaming and content creation despite ongoing memory shortages.
