One of the most famous leakers for NVIDIA GPUs has just confirmed a key detail about the upcoming next-generation Ada Lovelace GPUs from the company. The brand new architecture will be built on TSMC's 5nm process. This is massive news if true - and let's talk about that for a second. Kopite has leaked pretty much all the details of the Turing and Ampere architectures and has historically been extremely accurate. That said, as always with leaks and before multiple confirmations, a grain of salt never hurt anyone.

Kopite had already previously confirmed that the Ada Lovelace architecture would be built on the 5nm process, but it was assumed that this would be a Samsung node. NVIDIA had made the (correct) decision to transition to Samsung for foundry services because it had (accurately) forecasted the demand that would be hitting TSMC. Having to share resources with Apple and AMD was a gamble and NVIDIA's decision to go with Samsung appears to have been mostly validated.
