I'm going to try and be one of those 8K people...hopefully PowerColor is one of the partners. If you guys got any info on where I would go to pre-order I would appreciate it.Quote:

Since I own a 780 Lightning I'm going to wait and see how it all comes out. If r290 is a beast then I might wait for the Lightning version of this too.
Fun times ahead boys
:D
I'll be damned they really are going without a crossfire bridge. Why?
Why not just redesign the crossfire bridge. Its not like sli where the bridged is packaged with the motherboard.
One of the things that I really loved about crossfire was that tri-fire works natively with Ivybridge and Haswell on motherboards like the Gigabyte UD5H. I can't imagine that this won't require more bandwith from the pci-e slots and possibly bottleneck a pci-e 2.0 x8 or pci-e 3.0 x4 slot.
Well, not that PCI-E 3.0 is any bottleneck really. Why not put the excess bandwidth in good use and at the same time shave off few cents from the board's BOM by omitting the CF link.
A lot of people use motherboards with pci-e 2.0. I can't imagine that this wouldn't bottleneck people running those boards especially since most default to x8.
Like I said about tri-fire it'll probably also cause issues at pci-e 3.0 x4 like the Gigabyte UD5H (works great for 7970 trifire) and MSI Mpower. I don't see how this has any pros for the consumer.
I agree. I think they rushed their decision a bit too much.Quote:

I guess there are two reasons to go with this: cutting costs, and they couldn't figure out how to solve all frame-pacing problems with the double-connection scheme.
Not likely.Quote:

so unless anything says different 2.0 wont have any performance hit with crossfire.
most amd boards are 2.0
most interesting is this:
Attachment 131371
AMD doesn't even have a PCIe 3.0 chipset for their CPU's, if they say there isn't a performance hit then I don't think they were relying on PCIe3 to make up for the lack of the bridge.Quote:

direct access between gpu display pipelines over pci express.
explains it all.
plus wasn't it already talked about that the crossfire bridge only has the bandwhich of a pci-e 1x slot, with lower latencies. didn't have much use in recent crossfire as it was evolving and became redundant.
surely the optimized it and now left the old method behind completely.
this new slide shows , alternate frame rendering isn't the method used anymore.
might even mean , the texture ram issues of crossfire are gone to.
How good is mantel vs DirectX 11 in terms of picture quality and dos it have tessellation for example? or is this going to be basically OpenGL but faster?
Hi All Friends.
Sorry, Please Explain To Me DMA Engine In RADEON R9 290 X OR PCI - EXP .
Thank You.
I went X1950XT > 4870 512MB > 7950 so 4 years wait isn't too far off for me :p:Quote:

ATI's X1600 and X1900xxx could CrossFire over PCI Ex. without the cable, that was before the they had bridges.

I figure it wouldn't be too hard since those two cards should outpace my 780's oc'd speed by around 40-45%, and a new chip isn't likely to be much faster than that over GK110 anyway for the initial Maxwell 20nm chips. Combine that with trucking on a 2600K oc'd still from when they first launched (literally day 1) and I may have to turn in my badge :p: !Quote:

You are right.. You had the conector wired on the DVI of the master card ( one cable was go to the slave, and the second to the monitor ). ( i have got CFX with X1800PE 512 ( huum not sure for this one, i remember have buy the X1900 only 2 months then > X1900-1950XTX > 2900XT > 4870 > 5870 > 7970 ( and SLI too at same time from the 6600GT SLI ) ( I have even still nearly all gpu here. )Quote:

Pretty sure PCI-E is already used for these purposes (for a while). The secondary physical link is just reducing the load.Quote:
