AMD RDNA3 GPUs confirmed to be based on the 5nm and 6nm process nodes

AMD has already confirmed we'll get RDNA3 graphics cards later this year, but we still don't know anything official when it comes to specifications or performance. Slowly but surely, those details are beginning to come to light, with one AMD engineer confirming that the upcoming GPUs will be based on the 6nm and 5nm process nodes. 

The engineer's LinkedIn profile, found by @blueisviolet (via VideoCardz), shows that RDNA3 GPUs will be based on the 6nm and 5nm process nodes, most likely manufactured at TSMC. According to the profile, the Navi 31 and the Navi 32 will be based on both nodes simultaneously, giving more credibility to the rumours surrounding AMD's use of an MCM (Multi-Chip Module) design. On the other hand, the supposedly monolithic Navi 33 GPU will only use the 6nm node.

this why on some my previous twit
i said rdna3 will probably start with 5nm

As for the MI300 GPU listed in the profile description, this one is expected to be AMD's first MCM-based product. However, unlike the Navi 31 and 32 GPUs, it will be solely based on the 6nm process node (probably also TSMC).

The AMD engineer has since removed the information about the unannounced GPUs. Besides RDNA3 graphics cards, AMD also plans to launch the first Zen 4 products later this year.

KitGuru says: This information isn't a complete surprise for many of us, but it's still enough to confirm some reports we've heard. Hopefully in the months to come, we'll start to see and hear more about performance and the improvement we can expect over RDNA2.
