ATi HD 3870 X2 (R680); Official Specifications & Images

[mascaras]

Did you read my post? I said deplorable COMPARED TO ITS SYNTHETIC SCORES.


I was just making a note that just b/c a has a higher 3dmk score, doesnt mean it will perform better IRL (gaming).

yep , 8800GT/GTS also scores higher than 8800GTX/Ultra and in games they are not better

Higher 3dmark score doesnt mean = better in games , we already know that


about HD3870X2 and 9800GX2 performance in Games will always depends of drivers support , same history like SLI/CF

Wow - hope that's true. That's a darn good dual-3870 x-fire-range number. Got 17k with a QX9650 at 3GHz stock with dual-3870s in x-fire.

Benchmark leaked

They show three DMARK06 tests to 2560 by 9573 resolution at X1600
(SM2.0: 4494分, SM3.0/HDR:4476分). 看來如果以1600X1200 或是1280X1024測試, 分數是很高的! (SM2.0: 4494 points, SM3.0/HDR: 4476). View to 1600 if the 1280 X1024 or X1200 test scores are high!

thats with a phenom aswell.... a c2d / c2q would be more no?

Google translation:

ITOCP released several photos R680, R680 and their release of the results.

從相片看來, 這張R680不似早前放出的諜照, 可能ITOCP得到的是非公板R680. It seems from the pictures, this does not seem R680 earlier release of the spy photos, may be the non-public ITOCP plate R680.
看看照片, 大家可看到2粒繪圖核心在卡上, 需要2組額外電源供應. 中間的晶片可以是否類似在X1650時代用的PLX 晶片, 安排PCI-E 頻寬給2粒核心. Look at the photo, you can see the two graphics cards, the two groups need additional power supply. Intermediate whether similar chips can be used in times of PLX X1650 chip for PCI-E bandwidth to two core.

網頁報導, 這於速度是770/2250. 在現時的驅動, 只認作HD3870. 但是在CCC 控制台中, 大家可看到它的接口是以PCI-E 2.0 X8 運作! 以及共有1024MB 記憶體. Website reported that the rate is 770/2250. In the current drive, only recognized as HD3870, but in CCC console, we can see the interface is PCI-E 2.0 X8 operation! And a total of 1024 MB of memory.

That's not the reference card, it's the Unika one.

I wonder why ATI decided to leave the switch chip as it is, it wouldn't have taken long to redesign it for 90 nm, 65, whatever, and have TSMC to make it way smaller than it is right in that picture.

[Bo_Fox]

What's that huge chip in the middle??? Is it some kind of a magical solution that makes those dual GPU's work together as a "single" GPU so that it is always scaled in everything like a magic crossfire?

Yeah its the PLX bridge chip. In other words, internal, intergrated Crossfire.

How'd you determine that?

Because AMD buys it from a 3rd party, i.e. they have no rights to the design and cannot have TSMC shrink it for them.
As to why they went 3rd party is because they are planning on integrating the PLX into R700.

How'd you determine that?

By knowing what he is talking about and doing research.

Well, it's certainly plausible, but you could at least reveal some aspects of your information source.

[Monkeywoman]

thats with a phenom aswell.... a c2d / c2q would be more no?

id say 1000 more for dual core and 1500-2000 more for quad.

[Jon Boy Deluxe]

I just don't see how this is going to be better than the GX2 if it is only 2x3870's in CF... 2x8800GT's in SLi will outperform this.

Surely?

I mean all anyone can do is speculate but from what I have seen so far, it isn't that impressive (the X2).

As ever I will reserve my judgments until I see an X2 vs GX2 shootout.

[cool_case]

True that 2x8800GTs will outpeform 2x3870s - by a little. But, the unknown is how well the onboard hardware x-fire performs vs. the hardware sli, that is, the hardware x-fire could get closer to the full power of two 3870s vs. how the GX2's onboard sli gets close to the full power of a pair of 8800s. ... or not.

That is not true...
CF HD3870 performs better than SLI 8800GT...
It scales MUCH better, as in it is pretty common to see 60-90% gains.

Its not like we haven't seen these before...

That's not the way I remember the comparative benches. I though that in most, but not all, benches 2x8800gt beat 2x3870's, but not by much.

BTW- there is a button down in the lower righthand corner named multi-quote, so you can quote more than one post in your post.

I wouldn't call that "research" - that it's like it was in earlier models. I'd call that 'as we've seen before'.

But ... I'm not disagreeing that this is what the chip is.

It is a newer model though... We have seen these before but not this particular model.

This looks more like a tie between 8800gt sli and 3870 x-fire than a clear leader: http://en.expreview.com/?p=53&page=4

If this is any indication of what to expect I can see why many are excited:

Hey, I'm going to buy two of the 3870 x2's rather than 2x Gx2s, thinking they'll be better. (And I have 2x 3870s rather than 2x 8800gt's.) But, I'm trying to be realistic. It's not completely clear which will be better. I'm betting ATI - though - for the 1st time in a while.

[Scimitar]

The performance of the 3870X2 and 8800GX2 should be pretty close to each other, but in my opinion the ATI design is much better. A single PCB versus 2 PCBs. I'll take 1 in a heartbeat, especially if you want to go subzero. Have fun making pots for that Nvidia card.

[zerazax]

Hell you could probably do 2 HR-03's on the 3870X2.... only you'll take like 5 slots up lol

[Volkswagen]

when will I be able to buy this card?
