不好意思...在我的印象中...
SB700好像沒有內建PCI-E喔...
所以這片的X16跟X4應該都是從780G裡拉出來的
不知道是我記錯還是大大手誤？
回應主題...
話說780G的PCI-E不是已經支援到2.0了嗎？
就這次電腦王的測試
PCI-E 2.0 X4基本上已經可以餵飽一張高階卡(8800GT)八成左右
所以理論上這張主機板的X16+X4應該是不至於會拖累太多性能阿
怎麼感覺山豬馬克的總分沒有提昇多少阿... 
以上如有說錯請指正  |

We've spent a lot of time on integrated graphics, but it's not the only element of the 780G's new hotness. The north bridge also gets 26 lanes of second-generation PCI Express connectivity, should you want to add a discrete graphics card of your own. 16 of those lanes are reserved for an x16 link, while six are distributed across x1 links meant for expansion slots and onboard peripherals. The remaining four links are reserved for the chipset's north bridge-to-south bridge interconnect.
Follow the interconnect south, and you're greeted by AMD's eagerly-anticipated SB700 south bridge chip, which ultimately arrives with a bit of a whimper. The SB700 may be new silicon, but in many ways, it's just more of the same. Take the chipset interconnect, for example. The 780G has four lanes of PCIe 2.0 reserved for its chipset link, and while the SB700 can match its northern neighbor's lane count, those PCI Express lanes come from the previous 1.1 generation. This caps north-south bridge interconnect bandwidth at 2GB/s—half of what it could have been with a top-to-bottom PCIe 2.0 implementation.

另，3dmark05/06是很依靠CPU，Phenom雖然是原生四核，但效能的提升畢竟沒有CORE 2 QUAD好。 |
