Radeon HD 7xxx series?

I've got some questions about the upcoming ATI Radeon HD 7xxx series of graphics cards.

*Are these cards a completely new architecture or just a 28nm die shrink of the HD 69xx?

*Will they offer almost twice the performance like the HD 5000 > HD 4000 did?

*How much video memory will these cards have? More than 2GB?

*I heard that they are supposed to use GDDR5+ memory. What is GDDR5+?

*These cards are going to go along with the next-gen processors/chipsets motherboards from AMD and Intel, and will use PCIe 3.0 x16. Will they be reverse-compatible with PCIe 2.0 x16?

*Will they use a new version of DirectX?

*Are these cards due for release in 2011 or 2012?

*I've heard rumors about 2160p monitors. Will these cards support resolutions beyond 2560x1600?

  1. Based on rumors:

    *They are supposedly based on the same VLIW 4 architecture as the HD 6900 series.

    *Ideally yes considering how many more transistors they can pack into 28nm over 40nm.

    *Probably no more than 2GB, 2GB is overkill as it is in most cases.

    *No idea

    *PCI express is always backwards compatible, a PCI-E 3.0 card should work in a PCI-E 2.0 slot

    *Probably not, I don't think the specs for DX12 have even been finalized yet.

    *Supposedly we'll see a card or two by the end of the year.

    *By the time that becomes standard, you'd want a new video card anyway.
  2. Less power consumption less heat for sure, performance wise may see huge improvements maybe 100%+ lot more bang then what 5000 to 6000 series gave us, I

    Do you have anything to support that claim?
  4. No, he/she doesn't. As usual AMD is keeping everything as secret as possible. I don't think that the wait should be too long though.
  5. I wish we'd see a 100% performance improvement. but I dont want to get my hopes up too much
