ATI R680 PCB Design and Cooling Early Pics

Here are some leaked pictures from ATI R680, courtesy of ChipHell. What you'll see on the PCB are 2x RV670XT GPUs and one PLX chip for communication between the two cores. All the sixteen memory chips (8 on the front and 8 on the back side) are missing from the board, probably because of the early development stage (that's not a finished product). Source said the card is using 0.7ns GDDR4 memory.

only that this one sports 2 dies, and the gtx just one ;)

I think ATI can be allowed that one

Question is, could they run 4 of these in CrossfireX? Imagine harnessing the power of 8 GPUs! I'm sure support for something like that is far off and distant, but I'm pretty sure if properly usable, that would be quite a performance feat.

Looks interesting for sure, but I'm waiting to see what the actual product is capable of.

Hay guys.... from what i know.. that u can run only 2 of this card in crossfire.... because there only one crossfire bridge slot.....:rockout:

Hope it come with 1 or 2 Gb of GDDR4:banghead:

Look at the comedy:

NVidia's best cards have two SLI bridge extensions. This card being the best one from ATI has only one. The AMD Spider got pwned even before it took off.:laugh:

Where the hell are the memory banks??? Please don't tell me it's going to be AMD Cockroach (an evolution from HyperMemory + AMD's weird naming shemes).:roll:

EDIT: the card still is in the development stage and so no memory banks. I guess you can make a guess on how it performs right now.

1. Take two HD3870 cards, strip them across a x8,x8 lane Crossfire on a board like the Gigabyte GA-790X-DS4. Voila! benchmarks ready. I really don't think the PCI Express lane arbiter made by PLX does anything but to assign tasks for the GPUs. Well, that's what arbiters are meant for.

2x RV680 cards === 4x HD3870
AMD Crossfire X === Good as dead.

i am curious if 3x 7950x2 can be installed in SLI :)

Instead of wasting money on developing niche products that may never see the light of day (Spyder anyone?), ATI should be trying to fix the R600 series' crappy AA performance - or even better, pushing to get R700 out the door before nVidia releases their next monster GPU.

I thought they would put 2 cores in the same die, like CPU's, or even 4 cores!!

The R680 aka RV670 x2 is a 2 gpu, single PCB video card using a PLX switch. So far it appears that it will use a total of 16 ICs (8 in the front, 8 in the rear of the video card) and it is suppose to total Samsung 1 gig of GDDR4 at .7ns ram at 1400MHz (however nothing confirmed as of yet).

The PLX chip is unknown for the RV670 x2 but we do know that the HD 2600 X2 used a PLX PEX 8547 which is a Multi-Purpose, PCI Express Express Lane Switch. This chip has a latency of 110ns (x16 to x16), uses 48 lanes and 3 port PCI Express Switch. Here is a review of the HD 2600 X2 here. My only issue with this review is that AA should have been used. Using only AF only tells 1/2 the story at higher resolution. Here is another review

If a guess was made, the PLX chip on the RV670 x2 should be a gen 2 also using 48 lanes which would make it a PEX 8648 but there is still no confirmation on this yet. Only time will tell if this is true or not. Ultimately this video card will be very dependent on how profiled and tuned for multi-GPU usage each game is. This can be worrisome if you look at past CF and SLI gaming compatibility.

This product will last not more than a week, I've been screaming in so many threads now, ATI should work on a powerful GPU and not this. How much time does it take for NVidia to slap two 8800 GT cores onto a board and roll out a 8800 GX2?? What's going to happen to this two headed jerk then.


Increase ROP count!!!

^ An acronym that ATi got blind at.


@EastCoastHandle

Dude, just because I used a non-technical term "arbiter" doesn't mean I was getting to something other than what you highlighted. Contextually the word arbiter means switch. PLX is not the only company that made these for the HD2000 X2. Some cards even used one made by IDT.

ATI is the new 3dfx



This killed 3dfx.

EXACTLY MY FRIEND


This is exactly what 3DFX went thru before it collapsed. The AMD ATi merger had a lot of its top Canadian engineers quit to protest the merger. Look what it lead to.

Which is why I didn't quote you. No malice.

BTW, this is the IDT switch I was talking about

You'll need liquid cooling or a four slot cooler to keep 4 RV670s in operational conditions.
