AMD Radeon HD 7000 Series to be PCI-Express 3.0 Compliant
AMD's next generation of graphics processors (GPUs) that will be branded under the HD 7000 series, are reported to be PCI-Express Generation 3 compliant. The desktop discrete graphics cards will feature PCI-Express 3.0 x16 bus interfaces, and will be fully backwards-compatible with older versions of the bus, including Gen 1 and Gen 2. Motherboards sold today feature Gen 2 PCI-E slots, although some of the very latest motherboards launched by major vendors feature PCI-Express 3.0 slots.
The new bus doubles the bandwidth over PCI-E 2.0, with 1 GB/s of bandwidth per lane, per direction. PCI-Express 3.0 x16 would have 32 GB/s (256 Gbps) of bandwidth at its disposal, 16 GB/s per direction. AMD's next generation of GPUs, codenamed "Southern Islands" will be built on the new 28 nm process at TSMC, and will upscale VLIW4 stream processors. Some of the first PC platforms to fully support PCI-Express 3.0 will be Intel's Sandy Bridge-E. Whether AMD's GPUs have hit a bandwidth bottleneck with PCI-E Gen 2, or is AMD trying to just be standards-compliant, is a different question altogether.

85 Comments on AMD Radeon HD 7000 Series to be PCI-Express 3.0 Compliant
only thing i don't like about this new stuff is i doubt it will have xp drivers or be xp compatible :twitch::cry:
My comment was directed at the people who still use it as their main OS and refuse to upgrade.
6 months from now:
Nvidia fanboys: We got Physx !
AMD fanboys: We got PCIe 3 !
Personally, I don't give a damn. As long as Nvidia doesn't take the bait and rush Kepler like they did Fermi.
I can see the engineers over at Nvidia now.
John Nvidia: "Ok we got the PCB done now we just need to get the yields down and we will be good to go on Kepler"
Bob Nvidia: "Hey John that dick ATI Jim is on the phone. He says how you doing on Kepler because hes got PCI 3.0. What should I say?"
John Nvidia: "Tell that jerk we got PCI 3.0 too!"
Bob Nvidia: "But John we just got the PCB done.....we don't have PCI 3.0."
John Nvidia: "Is he still on the phone?"
Bob Nvidia: "Yeah?"
John Nvidia: "You are such a dip shit. Do you think he heard you?"

ATI Jim: (still on the line)
