AMD to Celebrate 30 Years of Graphics: Webcast and new product reveal.

I thought it was curious that this part has a 256-bit bus. Doesn't the 280X have a 384-bit bus? Also, 2GB?
Does this come in below the 280/280X in the AMD GPU hierarchy?

After all the fuss that was made back in the 680 vs 7970 days about 256-bit buses and 2GB ram seemed to be something AMD had moved past (I thought).

EDIT:
Personally not got the slightest bit of interest in Alien Isolation of Star Citizen.

The 7970 and 280 cards don't fully support project freesync, so a newer product that does was needed. This also sets the scene for the 290 refresh (hopefully) as they can use the same architecture and double the frame buffer + bitrate to have a very nice card, given the 285's TDP.
 
So yeah, what happened to the efficiency? And why have they even called it a different core?

From the specs (and the fact they've just called it normal GCN), it looks like they've LITERALLY taken the HD 7950 core and given it a 256-bit memory bus, and that's where any power saving comes from.

Although it's probably more accurate to say they've taken the HD 7790 core and scaled it up to HD 7950 size, again with a 256-bit bus instead of 384-bit.

Very disappointed that there's literally nothing at all new with the card (remember they mentioned ALL the GCN cards would support freesync and DX12 etc.)


EDIT: This card would make sense to me if it was meant to be built on 20nm (i.e. consume less power) and be the R9 370.

Yeah, tho they come in 2GB and 4GB variants, we will have to wait and see how they actually perform.
Going simply from the specifications it looks like its about 15% slower than the 280 given that the 384Bit Bus is 30% wider and actually adds about 15% to the performance from the 256Bit Tahiti LE to the 384Bit Tahiti Pro.

But its not Tahiti, its a smaller Hawaii which is a more powerful architecture, 8 Ace Units vs 2 and 4 Triangles per clock vs 2.

Corrected the list of the 10 reasons to get a 285. From my passing knowledge of AMD's line-up, I am fairly sure all these are available on the 280.

10. DX12 + Mantle
9. Powertune
8. GCN
7. Cool 3rd party cards.
6. Trueaudio
5. Eyefinity
4. Free sync
3. Performance
2. Price $249. So probably £239 :D.
1. Free games. Alien isolation and Star Citizen added to Never Settle.
 
NDA is gonna be lifted today i think, so we will see some review soon i hope.
im not totaly disapointed, from the rumours when i saw there was no HBM memory, i wasn't really expecting more efficiency, card didnt have anything special to put a show for it though.
the bundle is on the otherhand just great, epic ship for SC, isolation looking to be one of the best games of the year, and one of the first perfect game for VR.
still gonna change my 280X for a 285X 4Go, a crossfire should hold a 4k setup.
now waiting for Nvidia see their 800 series, if there will be anything new, or that 28nm has just been milked in every possible way already.
