An AMD Infinity Data Fabric design engineer has revealed as part of his work experience on LinkedIn details about the future Navi charts of AMD of 6 and 5 nm. Brian Walters works at AMD's Austin division, and he mentioned several products that haven't been officially released yet, along with details about his manufacturing node. Specifically, Walters lists several Navi 3X GPU coming this year and a new Instinct accelerator card.
In his “Projects” section Walters says that current and past projects he has worked on for AMD include work on “Navi31 (using 5nm and 6nm processes), Navi32 (5nm and 6nm), Navi33 (6nm) and MI300 (6nm) accelerator«. The description indicates that both Navi 31 and Navi32 will be multi-chip module (MCM) GPUs that will use a mix of manufacturing nodes, so the Navi 31 and Navi 32 larger ones are hybrid architecture GPUs.
Details of the future AMD Navi 3X
Going to Navi 3X GPUs lower-end, the Navi 33 would stick to a monolithic GPU design, with a single die fabricated at 6nm. Their trade names are expected to be those of the AMD Radeon RX 7000 series.
The fact that they reach 6nm and even 5nm indicates that they would be a significant jump. It was already the RX 6400 and the RX 6500 XT, which by using a 6nm process, gained speed and reduced their size and power consumption.
AMD confirmed that both RDNA GPU 3 as Zen 4 CPU they would arrive sometime in 2022 in a presentation last summer, and several executives have reaffirmed this time scale. Hopefully AMD will make an official announcement in the coming months if those cards plan to hit the market in the second half of this year.
