ATi 4870X2(R700) PCB Debut

[Mr.BSEL]

An article on Nordic Hardware says that there is indication out there that the 4870x2 will outperform 4870 crossfire by an average of 15%.

I think that the pc in the photo isn't working and that is only for demonstration. Just look at the cpu fan. It isn't working !!! So, they only had 2x6-pin cables and so they put them, because if it isn't working, it doesn't matter. All of the above of course is pure speculation.

Or it could be off . Occam's razor.

Why on earth would they show a mock up card? If it is a mock up card and is actually just light plastic, it looks very impressive. Its the real deal. What you can argue is that they could change the design from an ES version.

I think you misunderstand me, anyway maybe it's my fault cause my english ain't that good. Of course it's the real deal an not just plastic and of course is a working sample. I meant that maybe, and I'm just guessing here, that wasn't working and wasn't mean to work at the exhibition and maybe their psu had only 6-pin cables and so they put them even if it wasn't enough for the card to work. Anyway i'm saying all these only to mention that maybe 2x6-pin aren't enough for this card to work.

[ripken204]

um, look at the 6pin plug on the right. isnt that an 8pin socket but it has a 6pin plug in it?
would you even need the 8pin with a pci-e 2.0 board?

15% more than the 512mb 4870's?? or 1gb 4870's??

i want to chuck a 4870x2 in my lan and rig and im hoping a 620w is enough to run this.

Well a 4870 draws about 160 watts max I believe. So factor in say 80% more draw for another GPU, and it's nearly 290 watts. Ouch, I hope that is not true that's too damn much for a single card. Unless my numbers are wrong somewhere.

Uh, no, for the fan to be a 'blur' it must be moving faster than the camera's exposure time can snap it at. That's why most pictures will have the fan looking like it isn't moving. Even mine turn out that way. You have to lengthen the exposure time for the fan to become a 'blur'

[eddieobscurant]

hmm... i didn't think that, probably you're right

[annihilat0r]

With 4850's clocks, 4870x2 performs %15 better than 4870 Crossfire? I won't believe it until I see it

[Caveman787]

We don't know the clocks yet so far like everything else it's just speculation.

But considering it's 2 chips on one card it being faster then crossfire by a little bit would make a lot of sense.

[zerazax]

Well this PR slide that was leaked for the R700 in CFX shows 750Mhz clock. Not sure if they backed it down for release due to TDP or power draw or whatever, but this is what we had a few weeks ago that was leaked:

[annihilat0r]

WOW, then the cooler must be really awesome

If the score is true, then it looks like 4870x2 in crossfire scale very well since a single 4870 gets around 3600 on the extreme preset so theoretically, 4 of the 4870 would give 14400. The test shows 12515 which means about 87% efficiency, at least on 3d mark vantage.

[Caveman787]

Well as amazing as that sound's and wonderful as that would be I feel that is somehow optimistic.

Unless of course since the 2 chips act as one card and therfore the second double card acts as crossfire. It would then have scaleing similar to crossfire but with effectively cards that are double the performance of 1 4870.

Yeah that came out very confusing eh

[annihilat0r]

Let's see

Single 4870: 3,600
CF'ed 4870 (1.7x scaling for extreme preset): Around 6,100
Plus %15 for 4870x2 = 7,100
CF'ed 4870x2 (again 1.7x) = 12,100

Reported score: 12,500

Not too bad, eh

[Hu1kamania]

That is some damn good scaling! Very nice!

[emuexport]

I'll be waiting on one of these by the looks of it as it should save me upgrading my motherboard etc.

Cant wait to see some numbers and reviews, roll on August!

Settle down there Shirlock!
In case you havent ever noticed, cameras take pretty quick snaps. I havent seen a photo of cpu fan moving?? ever!

I have a bad case of the wants.

TDP is ~160w, realworld max power consumption is ~140w.
140x2=280w, which is why I brought up that they only need to cut 40-50w.

x12515 in Vantage x mode.

[Eson]

Does GPU-Z show 1GB memory on the HD3870x2?

[zerazax]

Good catch... no it doesn't

[xlimit]

I think this stuff only had one backward, the heat problem ....http://www.xtremesystems.org/forums/...lies/frown.gif

If it can go max 80 C under full load......i will grab it

Not too bad, eh

When you look at it that way the rumored score of 7K makes perfect sense. If this is truly only at 4850 core clocks then that is very impressive.
