From ExtremeTech: AMD’s Navi has been of interest to AMD fans since it first popped up on roadmaps, with hints of a next-generation memory subsystem and a “scalability” option that might be similar to the modular GPU designs that Nvidia is supposedly considering for its own products. First, the hints. As Hot Hardware reports, some driver notes for a Linux driver update back in July that were recently discovered reported:
[WARNING]: Should use –pci when using create_asic_from_script()
new_chip.gfx10.mmSUPER_SECRET => 0x12345670
new_chip.gfx10.mmSUPER_SECRET.enable[0:0]
GFX10 is a Navi reference, and there are plenty of other hints to ongoing Navi work at AMD, from a job opening for a senior ASIC design and layout engineer (Shanghai, China) to various statements from AMD that it’s working on 7nm ramps already (the remarks date to May of this year). A Navi tape-out now or in the next few months would clear the way for a professional product introduction late next summer or fall, with consumer cards arriving a few months later.
