As per a story from a Japanese news agency, NVIDIA might look towards Samsung and their new 7nm EUV process to fabricate the next-generation of GPU chips. Samsung started the risk production of 7nm EUV chips a few months ago and IBM has already announced that their 7nm Power Processors will leverage the Samsung node.
NVIDIA’s present Turing line of GPUs are built on TMSC’s 12nm manufacturing process. There are a lot of factors that will affect NVIDIA’s decision, from AMD’s response in the GPU segment to TMSC’s own 7nm yields. AMD is already expected to release their new Radeon Navi GPU architecture based on the same manufacturing process.
Some predict that NVIDIA might stick with TMSC’s 12nm node in 2019 and finally switch to Samsung’s 7nm EUV a year later, but the details are pretty murky and your guess is as good as mine.
Samsung was the first company to start risk production of EUV chips in October, while competitors like Intel and TMSC are still stuck on the 10nm and 12nm nodes, respectively.
