AMD readies three new GPUs: Greenland, Baffin and Ellesmere

“Greenland” will be AMD’s first graphics processing unit based on the all-new micro-architecture. While the architecture is currently known as another iteration of GCN, the new ISA [instruction set architecture] will be so considerably different compared to the existing GCN that it has every right to be called “post-GCN”, the source said. It is likely that the “Greenland” will retain layout of the contemporary AMD Radeon graphics processing units, but there will be significant changes in on the deeper level.

The only official thing currently known about the new architecture, which Mark Papermaster, chief technology officer of AMD, calls the next iteration of GCN, is that it is projected to be two times more energy efficient compared to the current GCN. Essentially, this means means major performance enhancements on the ISA level. Thanks to the fact that the “Greenland” graphics processing unit will be made using either 14nm or 16nm FinFET process technology, expect it to feature considerably larger number of stream processors than “Fiji”.

The “Greenland” graphics processor will rely on the second-generation high-bandwidth memory (HBM), so expect ultra-high-end graphics cards and professional solutions with up to 32GB of DRAM onboard with bandwidth of up to 1TB/s. Consumer-class “Greenland”-based products will likely come with 8GB – 16GB of memory. Due to usage of HBM, expect the “Greenland” chip and upcoming graphics cards on its base to resemble the currently available AMD Radeon R9 Fury-series adapters.

The number of transistors inside the “Greenland” as well as its die size are unknown. Since 14nm/16nm FinFET manufacturing technologies have considerably (up to 90 per cent) higher transistor density than contemporary TSMC’s 28nm fabrication process, it is logical to expect that the new flagship product will feature 15 – 18 billion of elements if it retains around 600mm² die size from the “Fiji”.

It is believed that AMD has already taped-out its “Greenland” graphics processing unit and is about to get the first silicon in the coming weeks.

Not a lot of information is known about the “Baffin” and the “Ellesmere”. The source stressed that both GPUs are brand-new and will be designed from scratch. Since the “Baffin” and the “Ellesmere” are named after bigger and smaller islands in Canada, it is likely that the former is a mainstream graphics chip with moderate die size, whereas the former is a small entry-level GPU. AMD began to work on “Ellesmere” about a year ago.

Expect AMD to begin talking about its next-generation graphics architecture in the coming months.

Boffins working on Baffin.
 
:D just as the rumours mentioned. AMD doing a full lineup of 14/16nm parts with HBM2.

They must have had these in the works for a while and were waiting on 14/16nm as i mentioned before. :)
 
These are the 2016 range.

I would expect they'll be like the 6000 series and replaced as soon as yields get good enough for a decent-sized GPU. The foundries cannot get to grips with finfets. They'll be quite a bit faster than Fiji but we're not talking anything like GeForce 7 -> 8.

Unless they have something special up their sleeve.
 
I just couldn't resist upgrading the 7970 any longer. One more year I said! Dam upgrade bug I knew something else would be lurking :D .
 
I don't think we will see any of this until the end of next year but AMD need to get off of 28nm and start again with new designs to compete with NVidia in all areas.

NVidia need to enjoy their market share on 28nm as they are going to lose a lot of it once we are away from 28nm.
