Some exclusive information has been shared by the guys over at VideoCardz about AMD’s upcoming Tonga GPU. Rumors had first surfaced about AMD’s Tonga GPU about a year ago when it was listed in a BETA Catalyst driver along with Hawaii and Vesuvius. Of course we know that both Hawaii and Vesuvius are already here, but we are still waiting on Tonga.
Tonga will be a mainstream processor, most likely being manufactured by Global Foundries. It will introduce some major changes to the AMD’s GPU architecture, but don’t expect a 20nm fab process or high-bandwidth memory. Tonga is most likely going to be a direct competitor to NVIDIA’s Maxwell GM107 chip. Tonga should bring a dramatic change in terms of power consumption. The Tonga architecture would also a new PowerTune Boost, which would operate at a much lower hardware level.
Tonga-based graphics cards should arrive in two to three months. It is being understood that Tonga-powered graphics cards will only feature 2GB of memory (at least on the reference model). So these cards will most likely be Pitcairn (Curacao) replacements.
Looking at AMD’s naming scheme the card will most likely be called the Radeon R9 275X, but from what we know the codename has not been finalized yet.
AMD is likely to talk more about this GPU around Computex time, which of course is coming up! Stay tuned!
