One of our most reliable sources, SweClockers,com has reported that the AMD Tonga GPU will actually be poised to replace the R9 280 and R9 280X respectively. That means that when we learned of the existence of this class a few days back thanks to our friends over at Videocardz.com the exact tier was speculated to be mid-range at best. However this new information seems to suggest that Tonga is actually the Early-High End Lineup of AMD.
AMD Tonga GPU could have 265 Bit Bus Width and 7Ghz vRam – Potential Nomenclature is Radeon R9 285
So basically, AMD Tonga GPU will replace the now aged Tahiti core, it also means that performance wise, it will be faster than the current Maxwell cards; namely the Geforce GTX 750 and GTX 750 Ti. According to the same source, the circuit actually looks like a scaled down variant of Hawaii albeit with a 256 Bit memory bus. AMD will probably compensate for this by using faster Memory Modules so 7 GHZ GDDR5 RAM is definitely on the table. We also no have word on pricing though the expected launch date is third quarter of 2014, probably August or September.
