Meet the red Maxwell 😀

280X specs but new and shiny tonga.

Lets see how well will 285 do vs 7970/280x as it has very similar internal block structure but newer architecture. I mainly wonder about 256bit vs 384bit bus. And if AMD implemented new HW level compression which will make memory more efficient from space and bandwidth point of view.

Did you even read the article? "The initial consumer graphics card based on Tonga will be the Radeon R9 285 which is expect to have 1792 activated stream processors making it perform at GeForce GTX 760 and Radeon HD 7950 level performance"

We'll see how good this thing overclocks. Tahiti was a beast.

To me this might replace the r9 280 considering the 280 competed against the 760.

I apparently did and for me "expect" means rumor. And it hardly matters if it is 285 vs 7950 or 285x vs 7970. And it does not matter if I paid 25% more for 7970 than someone other for 7950 since their performance per watt/heat/tdp is as close as 2-5%. Therefore it is not that hard to compare them based on other than performance per clock metric.

You know this speculation was not really take any risk : 7950 = 1792SP ... Ofc are we speaking about the 7950 ( 850mhz ) or the 7950v2 ( 925mhz). The question remain to see what is the clockspeed of this one. Lets be honest, i dont expect much about the performance of the 285 - 258XT version, i think thoses gpu's are more here for complete the lineup with the features you can find on Hawaii and Bonnaire: XDMA Crossfire, TrueAudio, same features level. Mostly maybe for OEM version, and this will be available in shop before the new line up is here. With this core used on the small cheap Firepro W7100 ( under 2000$ ) it was logical they release thoses parts too for consumer market.

In few days we will learn new details about Tonga graphics processing unit, as AMD is holding a special event celebrating 30 years of graphics innovation. AMD Radeon R9 285 and R9 285X This event will be the first place where AMD officially introduces Tonga GPU. Unfortunately, it is just a paper launch. First is R9 285, equipped with Tonga PRO, which will be available early September. Faster Tonga XT-based Radeon R9 285X will arrive few weeks later. So yes, there are two cards coming, both replacing Tahiti R9 280 series. Looking at the graphic above, you may find it disappointing that this event is just about Tonga. It is unclear, whether AMD is planning to show more than just a mid-range GPU. There are some rumors that AMD may give us a peak at a new roadmap, or maybe even first samples with HBM memory. AMD is currently working on Hawaii XTX, Maui and Iceland GPUs, all of them could be shown at the event, however we find it highly unlikely. The only processor that is confirmed to be shown at the event is Tonga.
