Indeed. Wonder when we still start seeing this incoporated into motherboard/graphics. Probably not till Intel Ivy Chips are released and next gen graphics?

Sandy Bridge LGA 2011 (arriving in Q3) is supposed to be using this tech.

Thing is, how clase are we to maxing out the current PCI-E 2 slots? I don't know much about this thing, but are they holding anything back? I'm not saying that this is pointless, far from it, more that it doesn't seem to be anything to get excited about just yet.
Maybe that's just me, though.

Maybe a quad chip GPU will max it...

Anyway, I can see this being handy for those with controller cards and a lot of HDDs/SSDs.

Its a good point, will next gen graphics cards reach the point where PCI-E 2 isn't enough. I guess for SSD's using PCI-E it might help

Agreed. It seems to be something that doesnt really have much of an effect yet....

It is interesting though and although i dont think we will be seeing much of it until late next year, im interested to see just exactly what its capable of.

one thing's for sure: your next graphics card is bound to murder your current one if paired with a PCIe 3.0 motherboard

what a load of crap.

Lol, indeed.


Though remember - this is from Endgaget. If its apple - it must be great, if the number is bigger then it must be had and anything older is instantly obsolete.

pci-e 2.0 is 2-4% improvement in gpu speed than pci-e 1.1 so i can't see pci-e 3.0 giving more than 1% improvement seeing as we are nowhere near maxing pci-e 2.0.

Isn't sandy bridge due in Q1 2011 now not Q3?

Indeed. Especially when a large number of crossfire/SLI motherboards have 1 x16 and 1x8 speed slot, and there is apparently not much lost from having one of the cards in the x8 speed slot? This may not be true anymore, I'm not sure, multi-card isn't something I've looked into, but if PCI-E2 x8 slots are almost fast enough, a PCI-E 3 slot seems somewhat redundant.

That said, I assume there's going to be far more than just direct speed changes, which will allow GPU manufacturers to get more power from the GPUs in other ways.
And maybe an increased wattage allowance for cards, given that there are some approaching the 300W spec limit, or is that limit written into a different spec?

yea AGP slots never got maxed out if i remember right? and the difference between pci1 and 2 is like 5% in real world gpu performance?

Yup - mainstream sandy bridge (based on the LGA 1155 socket) will be coming out on January 5th 2011. However this will only sport PCIe v2 (oh noes!).

The "enthusiast" grade sandy bridge is supposedly coming out much later - in Q3 with the magical PCIe v3.
