An AMD employee mistakenly confirmed the engravings of the upcoming RDNA 3 graphics cards through his Linkedin account.
RDNA 3 will indeed use 5nm and 6nm from TSMC.
With RDNA3, AMD should make a leap forward in the field of graphics cards, with the first consumer GPUs using MCM technology (already used on processors with chiplets). This generation, which is planned for 2022 (whose CEO Lisa Su reaffirmed the date a few days ago) would come more than double or even triple the performance compared to RDNA 2, with up to a maximum of 15360 shaders (against 5120 currently) accompanied by 32 GB of GDDR6 in 256 bits and an Infinity Cache of 256 or 512 MB. In parallel to its rumors, we had also been entitled to the engravings, namely 5 nm for the GCD and 6 nm for the MCD, which have just been confirmed by an AMD employee on his Linkedin profile.
Indeed, on the profile of an AMD engineer working on the Infinity Fabric (which has since removed the entire tab experience), we could see projects with the Navi 31, 32, 33 with the mention of the engravings used, including N31/32 in 5 nm and 6 nm (MCM) and N33 in 6 nm (monody).
