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.

If this is true ASRock is going to sell a shitload of boards because of it. Posted on Jul 18th 2011, 8:41 Reply

Power User Damn_Smooth I'm betting on "standards compliant". I'm gonna have to agree. I don't see most video cards saturating 16x 2.0 in the near future. I'm gonna have to agree. I don't see most video cards saturating 16x 2.0 in the near future. Posted on Jul 18th 2011, 9:38 Reply

The only use for PCI-E 3.0 will be for things like pci-e SSD which are the few things that actually use that bandwidth. Posted on Jul 18th 2011, 9:53 Reply

I'm guessing the dual-GPU 7xxx series might need more bandwidth, and the top single-GPU might suffer from x8 PCIe 2.0, but otherwise it's pretty much just another feature on the list. Posted on Jul 18th 2011, 11:03 Reply

My comment was directed at the people who still use it as their main OS and refuse to upgrade. Hey, I use it for legacy stuff. The machine barely gets turned on.My comment was directed at the people who still use it as their main OS and refuse to upgrade. Posted on Jul 18th 2011, 11:21 Reply

Graphic cards use far more bandwidth than any SSD available at the moment. Even the Revo thingies. Posted on Jul 18th 2011, 11:21 Reply

Performance Enthusiast RejZoR Graphic cards use far more bandwidth than any SSD available at the moment. Even the Revo thingies. yeah but pci-e 3.0 will allow pci-e SSD's to use fewer pci connectors and still get bulk bandwidth, for example fitting in a 4x @ 3.0 slot instead of 8x @ 2.0 yeah but pci-e 3.0 will allow pci-e SSD's to use fewer pci connectors and still get bulk bandwidth, for example fitting in a 4x @ 3.0 slot instead of 8x @ 2.0 Posted on Jul 18th 2011, 11:34 Reply

Any "extras" like this will be welcomed by me with open arms. Anything that helps it stay competitive with nvidia is fine by me. I just hope that there's a use for this and not just a pure gimmick to sell cards. But I'm sure the top end dual-card solution will be able to use a good chunk of the new bandwidth provided by the 3.0 interface. Posted on Jul 18th 2011, 12:07 Reply

Aleksander Dishnica Who said nvidia wont have pci-e 3.0??? btarunr It isn't a big deal. Kepler could be Gen 3, too. Whether it will support it or not isn't what matters. It's when will a Nvidia PCIe 3 supporting card be released. Remember DX11 and the ATI 5 series ? The first Fermis were DX11 compliant too. But still, the red camp kept going about how AMD was the first to get there.



Personally, I don't give a damn. As long as Nvidia doesn't take the bait and rush Kepler like they did Fermi. Whether it will support it or not isn't what matters.

Big Member btarunr It isn't a big deal. Kepler could be Gen 3, too. If it wasn't going to be.....it will be now :laugh:



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)

MilkyWay Does this supply anymore power to the card than pci ex 2.0? This was one of my first thoughts when I heard of PCI-Ex3 being around the corner. There were some rumours about that, but I haven't heard anything concrete yet. Recus It's for marketing.
