是啊 ~~
有關這功能如果關閉的話好像會影響不少效能說
但是這應該是原本會Enable才是阿..軟體誤判?:confused:
能幫我們眾鄉民查查嘛 :PPP:

One novel feature of the HD 4870 X2 is that it has an additional direct-GPU-to-GPU interconnect called CrossFire Sideport (XSP). The XSP offers an additional 5 GB/s interlink bandwidth between the GPUs but is not enabled at this time. Yes, you read correctly. The official reason why the XSP is disabled at this time is because that much bandwidth is not required with current applications and it will be enabled at some point in the future via driver update.
One major advantage of the XSP that I see is that transfers between the GPUs would have a lower latency. The Gen2 PCI-E bridge will certainly be fast, but it will take a short time to process the incoming data and send it out to the other GPU (<140 ns). With the XSP's point-to-point interlink this delay is eliminated. So my speculation is that AMD is working on using the XSP feature but the driver support simply doesn't work as intended at this time.

的確是驅動沒推動到它...真期待開啟之後效能差多少

我朋友稍早已經敗一張MSI 4870X2 它就在問我那個SIDEPORT OFF 是怎麼回事....

還以為8.8已經完全支援 看來還要再等一等了

搞不好明年顯卡正式邁向真雙核的領域那就更嚇人了...
這麼大一張的顯卡..看起來真的霸氣十足..
