AMD's next-gen 'Super Secret' Navi GPU teased

Navi-based Radeon teased, could compete with GeForce GTX 2080

AMD might be an entire generation behind with their Vega GPU architecture, but their next-gen Navi GPU architecture is due sometime in late 2018 and has turned up as the elusive "Super Secret" ID in AMD's new driver.




In the latest AMD's drivers, there is code that reads "new_chip.gfx10.mmSUPER_SECRET.enable[0:0]". Someone spotted the new Super Secret ID in the latest Linux release of Radeon drivers, but it could be Team Red having some fun with us.


Navi could be the first GPU from AMD that would see a scalable GPU design being deployed, with many smaller Navi GPU dies interconnected through AMD's super-fast Infinity Fabric technology. This means AMD could drop GPU cores from each die, resulting in less cores per die but multiple dies added together would give us a Threadripper-like GPU design.




AMD has also said that their Navi GPU architecture would use "NextGen Memory" which we have no idea about, and could end up being HBM3 or GDDR6. Considering AMD is already using HBM2 in their current fleet of Radeon RX Vega graphics cards, the shift to GDDR6 or HBM3 would be very interesting.
