While the release of AMD's new Radeon 300 series is quite close, at least judging from recent AMD statements and rumors, it appears that Fiji GPU will actually be the only new chip in the lineup while the rest will be based on current Graphics Core Next 1.1 and Graphics Core Next 1.2 architecture.
According to
a new report from Sweclockers.com, the codename Fiji GPU will actually be the only new chip in the upcoming AMD Radeon 300 series while the rest of the lineup will be based on either GCN 1.2 or GCN 1.1 architecture. According to recent rumors AMD's Radeon R9 390 and the R9 390X should be based on that same Fiji GPU, while it is still not clear what will happen with the rest of the lineup.
In case you somehow missed it earlier, AMD's Fiji GPU should feature 4096 Stream Processors and pack 4GB of 4096-bit High Bandwidth Memory from SK Hynix. There will be plenty of new features from the new GCN 1.3 architecture as well.
AMD will eventually launch a dual-GPU graphics card, codename Bermuda, which will most likely end up to be the R9 395X2. Earlier rumors also shed some details regarding the rest of the lineup, which include the Trinidad GPU, which will be the base for Radeon R7 360 series while it is most likely that Tonga GPU will be the base for Radeon R9 370 series. The Radeon R9 380 series will most likely be based on a Hawaii-refresh GPU, codename Grenada, which will not feature any architectural changes but rather just a clock increase.
Hopefully AMD will soon officially release at least some part of its Radeon 300 series graphics card lineup and we might have a clearer picture what to expect.
