NH: PCI-SIG reviderar – PCIe 4.0 ligger kvar på 75 W via moderkortet

Den rapporterade ökningen för brandbredd mellan PCIe 3.0 och 4.0 stämmer dock. Men de som hade hoppats på ett nytt Fury eller Titan-kort helt utan strömsladdar kommer tyvärr att få fortsätta vänta. Även om den kommande PCIe-standarden förmodligen skulle kunna leverera mer än dagens 300 W så kommer merparten av den kraften inte att komma ifrån moderkortet.

 

Tom's: PCI Express 4.0 Brings 16 GT/s And At Least 300 Watts At The Slot (Update: Not Quite)

Update, 8/24/16, 2:06pm PT:PCI-SIG reached out to tell us that the power increase for PCI Express 4.0 will come from secondary connectors and not from the slot directly. They confirmed that we were initially told incorrect information. We have redacted a short passage from our original article that stated what were originally told, which is that the slot would provide at least 300W, and added clarification:

  • PCIe 3.0 max power capabilities: 75W from CEM + 225W from supplemental power connectors = 300W total
  • PCIe 4.0 max power capabilities: TBD

New value “P” = 75W from CEM + (P-75)W from supplemental power connectors.
