Will be interesting if Intel's new chipsets that are coming 2017 will integrate PCI 4... would be nice...Or maybe AMD could steal a march and include it with their new Zen chipset...
This idea that pci 4 would support 300watt graphic cards is not realistic. that would put a strain on the motherboard manufacturers cause they would have to implement a mosfet array the way way its done for cpus. this would drive the cost of motherboards up and have more things on the board prone to failure

Really? You know something that all those very intelligent people designing this new standard don't?This idea that pci 4 would support 300watt graphic cards is not realistic. that would put a strain on the motherboard manufacturers cause they would have to implement a mosfet array the way way its done for cpus. this would drive the cost of motherboards up and have more things on the board prone to failure
My thoughts, too. The power still has to come from somewhere. The article implies that the power will be delivered through the connector which may imply that they are adding extra traces or using some that are currently unused - if any. Still, though, the extra traces implied by this article have to handle the power that wires are handling now. If you add an extra power layer and an extra ground layer, then it might be relatively easy from a MB maker standpoint, but those extra layers cost money.My guess would be the GPU connectors will be adapted and moved to the motherboard, Initially. Then the PSU connection will be altered to accommodate the extra 1500W's the PCIe slots may or may not need. If you ask me, I think things are fine the way they are. Power delivery is fine for the mass majority, no need in changing anything.
I forgot to mention the added capacitors a motherboard would need in conjuction with the pci express controller to deliver 300wattsWhy? The CPU needs these FET arrays to regulate 12v down to more like 1.2v!
PCI-e power would still need to be delivered to the card at 12v - no voltage regulator circuits needed on the motherboard.
If there is no voltage regulation between the PSU and the card slot, there will be no need in additional capacitors. The voltage regulation is for the motherboard components not the card slots. Cards will have their own voltage requirements and therefor their own voltage regulation circuit.I forgot to mention the added capacitors a motherboard would need in conjuction with the pci express controller to deliver 300watts
Do you really think that all of the people designing this new standard haven't thought of these "problems"?
Let's give them some credit, and assume they HAVE... then we can wait for it to actually be implemented on a motherboard and slam them then....
Yes... a power cable is a really nice thing... and for anything requiring more than the 300-500 watts, one will still be needed.... but let's keep an open mind as to whether it's needed for less than that... a bunch of REALLY smart people think it won't be... I'm inclined to have a bit more faith in them...I'm not slamming anybody. Just expressing my concerns with my own experience as a reference.
And the laws of physics is hard to bend. More power requires more copper to conduct.
Yes they might have solved the issue some way, but in my opinion, a power cable from PSU to graphics card is a safe and proven way of delivering the required power.
BOARD revision... not standard revision...Yep and that is why we often need board revisions. They don't always get it right the first time around.
Wow 300-500watt
what is that going to do for power consumption of the motherboard itself?
An interesting article appears at Tom's on this. Apparently, 225W will come from "supplemental connectors." http://www.tomshardware.com/news/pcie-4.0-power-speed-express,32525.html
