AMD's Navi GPUs has been approved to maintain the GCN design

AMD has already begun developing drivers for Navi on the Linux platform. The last code of the code shows that Navi continue the trend of GPU-based GPUs.

Phoronix recently discovered Navi references while monitoring various Git reservoirs. AMDGPU LLVM back-end is now seeing GFX1010, and with the GFX900 being a Vega, the GFX1010 can only be Navi.

The code snippets that indicate the use of the Google content network are as follows.


Phoronix claims Navi support is likely to be seen in the upcoming Linux 5.2 Kernel and may be held until Linux kernel 5.3 release. The current advertising windows for Linux 5.3 is stable and the September release. Linux kernel 5.3 may be the first Linux core to support Maini Navi, and assuming that Navi releases sometime between May and July, we may not see much support for these GPU units until Linux 5.3 is released. Until then, Linux users may be required to jump through a few hoops to get their shiny new GPUs working properly.

We've seen Navi in ​​the past as a post-GCN design, which means that it may override the GCN 4096 SP limit, but not so. Previously, claims were raised that the GCN architecture would require significant tweaks to allow for additional SPs, to the point where a completely new architecture would have increased appeal. The GCN was designed when 28nm was cut, and was not adjusted to exploit the benefits of 7nm.

The GCN is also a memory-hungry design that requires expensive HBM for performance gains, although Navi is reported to take advantage of GDDR6. This can be seen when comparing Radeon RX Vega 64 and Radeon VII. Both GPUs are based on the Vega architecture, with Radeon VII clock slightly higher, but with double doubling of memory bandwidth.

Currently, rumors indicate an option to reveal at Computex, followed by the full launch with Ryzen 3000 at 7/7, referring to 7nm.

At this point in time, we do not know much about AMD's next-generation microarchitecture, but what we know is that GPU naming programs will come back in a simpler and more familiar way, similar to the way in which P9 referred to R9 Fury GPUs and Hawaii referred to R9 290 GPUs. Arcturus is believed to be based on 7nm +.
