System component expansion interface PCI-Express could get its next major face-lift in 2009, following which products compatible with the interface could be out by 2010. The PCI Express Special Interest Group (SIG) is in the process of devising the new interface that provides devices with twice the amount of bandwidth as that of the current PCI-Express 2.0, that's 8 Giga-transfers per second (GT/s). it is said to be backwards compatible with older versions of the interface.
Changes in specifications are being made that allow this interface to support triple-slot, 300W (from the interface), 1.5 kg (roughly 3 lbs) graphics cards. Perhaps this is the ideal interface for 'heavier' products from NVIDIA, AMD, and soon Intel.

1.5kg? frickin hell, sure if your graphics card is solid steel....
great. they're going to support the cards i really DONT want.
i want small, lightweight cards with low power usage.

Soon you'll have a graphics card "ohm nom nom" avatar.

by: Mussels;892143i totally agree with you Mussels. i mean what the hell are they trying to do? throw us back in the PC stone age when the PC parts where as big as the mobo!!! if so i wold like to create a new company called AMD (advanced MEGA devices) who wants to join me??:nutkick::nutkick::nutkick:

P.S. i am not imposing something about AMD.:respect:
I'd expect them to reinforce the substrate and the slot with carbon nanotubes at least :laugh: Geez... PCI-E ports probably will need backplates now + bolt thru screws :laugh:
Silly Crap! I mean nothing even ended up using max Bandwidth on AGP and now they just keep making the pipe bigger and bigger?? Is ANYTHING actually running out of room on PCI-1.0 16x yet?? I mean c'mon this is getting a bit silly..
so this new slot will hold current cards without screwing them down, woot
by: INSTG8R;892164That's quite wrong. The first 8800's already slowed down on x8 slots and got severely crippled by x4 slots. So a 9800GX2 or 4870x2 will be bottlenecked by a single x16 slot(1.0).

Besides, the standard needs to be ready for future cards, not for last generation. For this reason AGP kept increasing bandwidth as well. The industry keeps moving on, whether you like it or not.
by: DanTheBanjoman;892180Add GTX280/260 to that list.

what dan said is right. We might as well get ready.

Well the 8800's used bridges did they not? that alone could contribute to that couldn't it?
Yeah I get things have to move on but 2.0 has barely become standard with only this last gen of cards supporting it and already its going up another spec.
by: INSTG8R;892218No, 8800 (G80) did not use bridges of any sort, it's GPUs such as NV40 (GeForce 6800 PCI-E series) that had bridges (bus translation logic).

I believe that the max current draw from the 2.0 spec is around 75 watts. At 300 watts this could mean that graphics cards that max out around 150 watts or so could get all their power from the slot and would not need a seperate PSU cable.
This would be nice for cable management in systems that did not use the behemoth cards.

This would mean more power inputs for the motherboard. The power has to come from somewhere.
True, but the power cable for the mobo is easier to hide as it is usually on the side near the PSU.
The GC cables have to either cut across the mobo our be routed around the side.
It was just a thought. :) Now if someone can figure out a way to eliminate all of the cables to the storage devices we will all have really clean cases. :toast:

Holy shit, 8 Gigs per second, thats overkill and beyond....
by: PCpraiser100;892407Remember what forum you are on. I don't think "overkill" is in our dictionary :D

I'm a little concerned when people say PCI-E 1.1 is bottlenecking powerful cards. Do you think it's a possibility that my P35 is bottlenecking my 4870 because it's not PCI-E 2.0?
by: oli_ramsay;892434unlikely. its more the dual GPU cards that would be bottlenecked.

1.1 has more bandwidth than 1.0, its dual GPU 2.0 cards on a 1.0 slot that are the concern.
by: oli_ramsay;892434Bottlenecking not per se, but it probably would perform slightly better on a 2.0 bus. I doubt the difference will be huge though.

by: PCpraiser100;892407A system may be considered "Overkill" for about a month. Next month it's still fun. Next month it's an average system. Then next month you're window shopping all over again.

Quoting myself : "I'll buy a system and put a lot of money in it and turn it on every morning thinking 'wow, I can't believe I built this!' A year later, I turn it on thinking 'Ugh... I can't believe I built this...' "
Maybe not that drastic. If you get a 4870x2 now, you can play all games maxed with high AA (except the poorly coded game known as crysis). In 2 years, you could probably still play games on max with a little AA, and a year later it's just maxed. Same case with my X1800XT. It play UT3 admirably, and even has a decent shot at crysis. I like my card, but it won't be enough for me for very long. XD gunna give it to mom eventually.
Tom's Hardware already tested it. This is how PCIe bandwidth scales the performance:

I wouldn't say we can talk about bottlenecking, even 4x (8x on PCIe 1.1) offers very good results overall. Meaning that you probably won't NEED PCIe 3.0, just as you don't need PCIe 2.0 right know. That doesn't mean is not necesary, because it does help a bit, the more the better, and as long as it is totally backwards compatible, and seems it will be, what's the problem?
On another note, this interface's 300w are probably for Intel Larrabee, so that POS can run on a computer without requiring a nuclear plant by the side of your PC. :D

I'm all for the bandwidth...It's the 3 LBS cards that bother me a little...I not a fan of small form factor, but a 3 pound card seems rather ridiculously large.
I think the only addition needed was the 300W support (to negate the need for power plug on a lot of cards). The extra strength for heavier cards is nice, but with rising copper prices i think heavy heatsinks will be replaced with vapor chambers and watercooling.
Did anybody bother to weigh the 3870x2. Its 0.6 kg or 1.32 lb, heavy as hell for a card.
That must be one beefy slot to be able to hold a 3 lb card...something that's twice as heavy as the 3870x2. MONSTER :eek:

not with the energy crisis the world has.
by: Megasty;893021Bet if weight of a 3.0 graphics card was judged by length, the hardware girls at the booths would be jealous since they wish they had that card, for a reason LOL :laugh:

by: Megasty;893021Yeah...I agree with earlier statements that MFG's should be going smaller as they go faster...but I guess if they can slack in the smaller and lighter, they can still go faster! lol!

At 3 pounts there'll have to be either extra layers on an MB PCB, extra re-inforcements of not only the slot but integrated in the board, and maybe some sort of adjustable stabalizer bar that attatches to the card and either goes to the bottom of the case (allowing that there is clearance and no objects in the way) or towards the top or front...I just don't see 3lb vid cards practical or good on anything in the long run...that will have to lead to some serious distortion, possibly some serious damage/shorting too? Hopefully we don't have to fear something heavier than the X2's out there!
:toast:
I heard this about a year ago just was not a fixed date. Bound to happen sooner or later and with how things are going sooner is how it ends up being.
So those who hope for a system taking less power well looks like thats gone out the window lol.
