New details have surfaced about AMD's rumored Tonga GPU. According to SweClockers, the chip is going to power a new, higher-end member of the Radeon R9 280 series—and AMD is planning the launch for "late August to early September."
The tip comes from "Taiwanese sources," who also told SweClockers that Tonga will come in two flavors, both with a 256-bit path to 2GB of GDDR5 memory. Tonga will "primarily" power the Radeon R9 285, SweClockers says, but in the "longer term," the chip will also replace Tahiti in existing Radeon R9 280-series parts.
That jibes with another report we saw earlier this month. While that story didn't bring up the R9 285, it did outline Tonga's fate as a Tahiti replacement in existing parts. I guess we're still in for a bizarro world reverse-rebranding. (Thanks to Fudzilla for the link.)
