ATi 4870X2(R700) PCB Debut

[bowman]

Don't really care about heat as long as it can handle the heat without throwing a hissy fit.

[tdream]

The R700 boards were clocked at 778 MHz core, while the GDDR5 memory was clocked at 980 MHz QDR (effectively 3.92 GHz).

This thing looks awesome Black is sexy

Same source I assume, how come the clocks are different?

[zerazax]

Things might have changed since then? That PR Slide was from about 2 weeks or so ago which is an eternity....

Interesting to see that GPU-Z did detect 1GB while for the 3870X2 it only detects 512MB. Does GPU-Z actually detect memory or is it just a database even for the amount of RAM? I'd think that detecting RAM on a GPU is one of th easier tasks...

[Helmore]

You do quite a bit of double posting Zerazax , you first ask thing over at Beyond3d and then here .

But to answer your question; I don't know
I'm also doubting the clocks, R700 at 750MHz. just seems way to high to me for the power figures that have been stated in some earlier articles and it's not like they have to outperform 4870 in CF. They only need the single card performance crown....

[zerazax]

Well neither has produced an answer so I'm going to keep asking

[gojirasan]

They only need the single card performance crown....

I think they will lose some market share to 4870CF if it's slower. The people who buy these sorts of things are looking to have the fastest solution possible. Only some of those people actually care about how many of their PCIe slots are taken. In my own case I am using a uATX board with only one PCIe slot. So it is more compelling. But most people with an X38, X48, or X58 should be able to run CF without much of a downside. That is unless the 4870x2 really does have some new tech in it's CF implementation.

[Helmore]

It probably will have some new tech in it's implementation and if they only price it at around 150% of the price of a single 4870 then it is justified to not perform faster/same as a 4870 CF set-up.

[adamsleath]

would be very impressive if these worked well in xfire.

churnem out baby.
and work on them drivers

power seems pretty good for such a monster (gulp)

[halo112358]

Oh man is this thing ever going to run hot :p

[adamsleath]

'support global warming(or cooling/ wtf), upgrade your graphics solution now!'


i can only game for 1 third of the time due to tdp, but oo it looks good

[disruptfam]

Oh man is this thing ever going to run hot :p

im hoping some1 comes out with a single slot air solution to cool both gpu's

[Shintai]

15000rpm fan?

[clonez]

that is actually doable.. but not with normal copper or aluminum coolers (resulting in a much too high cost)

[adamsleath]

im running out of vram at 19x12 4xAA with my 8800gt (still m2tw) - rivatuner tells me so:



@504MB vram-> big stutter/lag and fps drop.

i think im low on bandwidth aswell.... cos similar lag effect occurs when vram not maxed.

[fornowagain]

Things might have changed since then? That PR Slide was from about 2 weeks or so ago which is an eternity....

My point was its the exact same score? Higher clock, what it got slower

AMD’s team in Austin managed to use two R700 dual-GPU graphic cards (four RV770 chips) to get a score of X12515.

[halo112358]

15000rpm fan?

Just take the motor out of a 15k raptor...

[Macadamia]

nVidia's GPUs hog more RAM in general.

[YMAA]

*want*

[Helmore]

nVidia's GPUs hog more RAM in general.

Maybe not in general, but their G80 architecture and everything derived from it do compared to ATI's HD2xxx and higher series (R600 and derivatives). At least that's what testing with their HD3870 cards has so far revealed, it could be different with these cards....
Although I doubt that....

[AliG]

That's very true, and from what it seems, the 4850 doesn't lose much ground to the 4870 due to memory bandwidth either, if you factor in the clock differences the bandwidth really only gives an extra 2-3% and that's only with max details. Thus I am extremely happy with my 4850 since I only paid $150 W00TZ!!!!!!

[RPGWiZaRD]

Just wanna comment on the color as so many are "black PCB omgwtfbbq". Just cuz this sample is black doesn't have to mean retail cards will be. Same concerned early NVIDIA samples in the past, was colored black but retails appeared the usual "green". That's the first thought that popped up in my mind seeing the black PCB at least. I wouldn't count on it that it will be black that's all, but what does the color really matter anyway?

[AliG]

Well diamond's OCX Black edition has to be black for sure, but other vendors could go with the traditional red. But black just looks so much cooler with that red and black heatsink blower setup, I don't think ati would change that especially with how awesome the gtx 280 and 9800gx2 shrouds are. If anything, nvidia is great at designing shrouds and to the least ati can use a black pcb

[annihilat0r]

The R700 boards were clocked at 778 MHz core, while the GDDR5 memory was clocked at 980 MHz QDR (effectively 3.92 GHz).

Where? In the SS it shows 750 Core, 900 QDR.
