QUOTE I should warn everybody now that the PCIe 2.0 bridge is actually a PCIe 2.0 to PCIe 1.1 bridge. What does this mean? Well, it means your PCIe 2.0 card will basically be bottlenecked at PCIe 1.1 speeds when communicating to the CPU. False marketing from NVIDIA. Here's a simple diagram of their "bridge": . PCIe 1.1 upstream port to HOST ..........______|_____ .........|..................| .........|...."Bridge"....| .........|..................| .........|___________| .............| | | | . PCIe 2.0 downstream ports to PCIe slots. The only improvement that you may see with this is that communicating between other GPU's through the PCIe slot will be at 2.0 speeds (which is highly unlikely because NVIDIA uses their SLI bridge connector, not the slot). AMD has TRUE PCIe 2.0 so EVERYTHING will be happening at 2.0 speeds. source: http://www.techpowerup.com/?45238 |

QUOTE(jinaun @ Nov 24 2007, 09:01 PM) Wow... nvidia also cheats in mobo chipset?? That's even more "creative" than hacking video drivers to win more FPS. What's wrong with them? |

PCIE 2.0 card bottleneck at 1.1? How is the performance margin between using 1.1 and 2.0?

according to those discussion .. i would think that 780i is an updated 680i with extra pcie 2.0 bridge thrown in
the use of pcie 2.0 bridge is meant to increase intergpu communications and at the same time, it does not need to go through the northbridge.. while pcie 1.1 from 780i is sufficient to broadcast graphics data/command to those vga cards ... right???? lol this is sample diagram i understand from it.. (dun tembak me lahhhhhh, me noob) i'm assuming the 680i's update.. whoops.. i notice that 680i has onli 1 pcie 16x 1.1 from its northbridge...

Reading up on it, but can't draw any conclusions before some pictars of the chipset itself are given with some relevant pin out data (the tracks are the easiest way to see the bus width)
Generally i can't be bothered to look for now as my exams are here  . Go ask fishy. |
