Radeon HD 7xxx series? Tags: Graphics Cards HD Radeon Graphics Last response: July 26, 2011 2:40 AM in Graphics & Displays Share ambam July 25, 2011 10:28:22 PM 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? More about : radeon 7xxx series turboflame July 25, 2011 10:39:44 PM 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. redeemer a b U Graphics card July 26, 2011 12:30:05 AM 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 Related resources Gtx 660 [non-ti] or Radeon HD 7850 - Forum Radeon 5850 cf vs gtx 580 - Forum [Solved] Urgent Advice needed.
