ATI Radeon HD 3870 X2 - Fastest Yet!

The R680 designates, in reality, the Radeon HD 3870 X2, which is based on two RV670 GPUs. As we've seen, the history of multi GPU cards is pretty diverse and if this HD 3870 X2 represents a departure from the concepts behind the Voodoo 5500 (the VSA 100 having been conceived to be grouped at least in twos, from the beginning, to produce an efficient card), its goal is reminiscent of the Rage Fury MAXX in 1999; to offer a product to place in front of the high end models of its Californian competitor.

AMD has decided to integrate two RV670s on the same PCB (for more information on the chip refer to the Radeon HD 3850 and 3870 review). This is, without a doubt, to allow the installation of a imposing cooling system and to facilitate the interconnections between the two graphical sub systems. The result is a monster of 26.7 cm in length (longer than the width of a motherboard). This value is identical to what we have on a GeForce 8800 GTX and Ultra, which holds only one chip.

Still i'd prefer to see an actual multicore ( 1 die and 2 cores) scenario maybe if they can do that they'd be able to cut off half of that behemoth. when i read 26.7cm i got my ruler out and had a quick measure just to see if it'd fit but alas it does not im 4cm short ohwell crossfire x 2 HD2600xt's will have to do for now :cheeky:

I remember the time when nVidia tried to cheat on 3DMark results just to beat ATI in their Radeon scores

I am glad now to see that ATI didn't walk on that same road and instead brought something new to the market with the first multicore VGA card

I wish 3dfx was still alive to see some more competition in the market

I remember the time when ATI tried to cheat on Quake III results just to beat nVidia in their GeForce scores.

I am glad now to see that ATI didn't walk that road alone...

How?

I'm back aboard the ATI wagon these days. Maybe they're not doing so well vs. Nvidia, but it wasn't long ago when Nvidia was in the same boat. Version 8.1 of their drivers (with the hotfix ) has fixed the problem us AGP users have been having for a while now, and my HD 2600PRO that came in this morning rocks!

I was all set and ready to jump on an Intel computer with an Nvidia 88XX card, but my girlfriend's computer I bought her is just outstanding, even with a 7600GT. (Spinning around in Oblivion with 0 lag is awesome) I dunno. When I sit here and read the forums, it's very easy to get all psyched up for high-end stuff. However, when I look at my bank account, it's quite the opposite reaction.

Both AMD and Intel are good, just as ATI and Nvidia. It's all a matter of how much you want to spend and if that cost justifies the performance gain is all.

gave me the most laughs of any review ive seen on a gfx card so far....latest ati technology barely gives over a year old nvidia gfx technology some competition. ati still has a long way to go. strike 2 for them. just wait till nvidia releases the 9800x2....that should catch them up for another 2 years...and to think that have had it ready for several months now and have just been waiting...ROFL!!!

This card is HOT and Quick if you look the benchmark on Anandtech.

But it's not that hot if you look on HardOCP.

So.... Who is doing it the right way?

That's the problem: there is *no* industry accepted "right" way. AT and Tom's paint the card in a very positive way (from what I have glanced at on the net) and HardOCP paints the card in less rosy colors.

And what happens next month when the 9 series gets released and Nvidia wipes the floor with this card?

Sort of answered your own question there, but thanks for showing your colors. We were all dying to know what they were.

I think the question posed Eis, was rhetorical. Ergo, he knew the answer.

the graphics gpu is far more complex than the core2duo as it is so why would u want that or they would put them on graphics cards instead

links don't work

tom's server disallows linking to images, they need to change it to link to the pages instead.

Weird, on my PC it works (maybe because i have seen the pages already (?))

Link modified to Toms Hardware Home Page.

all we need is a core-2-duo-like equivalent architecture from nvidia or ati to see more performance gains, price drops and far less power consumption.
