NVIDIA next-gen GeForce RTX 40 series to use TSMC N5 process instead of Samsung

Industry insider provides confirmation on NVIDIA Lovelace architecture process architecture.

Kopite7kimi is a leaker who correctly predicted almost the whole NVIDIA Ampere lineup many months in advance. Naturally, each word the user shares on Twitter is meticulously analyzed. The same applies to his recent NVIDIA leaks.

The user now reaffirms the rumors from July, when Greymon55 (another leaker although better known for AMD content) revealed that NVIDIA is planning to use TSMC N5 process technology for their next-gen gaming architecture known as Ada Lovelace. Now both leakers now agree that NVIDIA Lovelace is using TSMC rather than Samsung.

The same leaker revealed that Lovelace GPUs will actually a bit sooner than previously expected, although no dates are given it is rumored to launch by the end of next year. NVIDIA may want to keep its 2-year cadence of new gaming GPUs, which would be around September 2022.

Unlike AMD, NVIDIA is not planning to use a multi-chip-module/chiplet design for its upcoming series. Instead, NVIDIA will keep Lovelace monolithic, at least the flagship GPU known as AD102 is. So far there hasn’t been much information on any other Lovelace GPUs such as AD104 or AD106.

The rumored specifications of NVIDIA AD102 GPU equip it with 18432 CUDA cores and performance nearly twice as high as GA102. The AD102 would be a large 600mm² die consuming 400-450W using a smaller and more efficient node.
