Nvidia hasn't announced them yet but laptop vendors confirm that RTX 5050 and 5060 GPUs are almost here, and they'll both have 8 GB of VRAM
They've been rumoured/leaked about so much that the GeForce RTX 5050 and 5060 GPUs are almost certainly 'official', even though Nvidia itself hasn't said anything publicly. However, some of the biggest laptop vendors in the world have decided they'll just do it anyway because everyone and their grandma already knows about them.
The confirmations were spotted by Videocardz which noted that Lenovo, LG, and Razer were also listing the RTX 5050 and 5060 laptop GPUs on some of their product pages.
