AMD Prepping Post-GCN Greenland, Baffin and Ellesmere GPUs
Samuel Wan / 5 years ago
According to multiple sources, AMD is working on 3 new GPUs as part of their 2016 lineup. Likely part of the Arctic Islands release, the 3 chips all fit the theme being called Greenland, Baffin and Ellesmere. Greenland is set to be the flagship product while Baffin and Ellesmere will probably target other segments like performance and mainstream.
While we’ve already gotten some information about what Greenland will look like, we’re also learning that the ISA (Instruction Set Architecture) is undergoing major changes. Since 2011, AMD has been working with GCN, or Graphics Core Next. There have been several iterations from the original GCN 1.0 like 1.1 which powers the R9 290/290X and GCN 1.2 which is found in the R9 285 and Fury/Fiji. With this latest ISA change, AMD is moving beyond GCN to “post-GCN” on a radically new architecture. In some ways, the time spent with GCN highlighted how AMD has a slower cycle than Nvidia but also showcased the staying power of the architectures, which is finally seeing AMD’s early invest pay off with DX12.
This new ISA is also set to net AMD massive gains in the power efficiency department. While Nvidia showed strong gains moving from Kepler to Maxwell, AMD is reporting that their new ISA will double power efficiency. This should leapfrog Maxwell and will likely be a strong competitor to Pascal. Given the use of either 14nm or 16nm FinFETs as well, we may well see even more massive power savings. Combined with up to 32GB of HBM2 which is also pretty power efficient, 2016 looks to be a pretty big year.
Both Baffin and Ellesmere are also expected to be entirely new cards as well. This will bring a much-needed refresh to the AMD lineup which largely consists of rebrands at this point. Hopefully, these new cards and Zen will bring enough to the table and turn things around for the beleaguered firm.
