ATI Radeon HD 4870 X2 - R700 Preview: AMD's Fastest Single Card

Power Heat and Noise
This is prerelease hardware and software, so we can't really go in depth on these issues until we have something more final. We were told that idle power is not what it will be and so not to test it at all. We did, however look at load power.
As for heat, this card doesn't get any hotter to the touch than a single 4870. The HSF is much heavier than either 4870 or 3870 X2, and is very likely the reason the heat doesn't stay in the system.
Hot surface
On the noise front, when gaming it does spin up, but it isn't any louder than the GTX 280 at max fan speed. Again, we'll want to wait until we have final hardware to do quantitative tests on this, but it is nice to see that even the prerelease hardware doesn't go crazy in terms of heat and noise.

I look forward to Anandtech testing. Other sites - some good, some biased, some illiterate, etc.I describe Anandtech testing as thorough, fearless, accurate, brutal, relentless, and uncompromising. And few typos/language issues. And this results in far fewer fanboy/junk comments as well.
If I want the real truth, I come here, and I read it slowly - it's like a feast.
Thanks Anand and company.

On page 7:It is likely that the extra 512MB of RAM available to each GPU has significantly impacted perforamnce since we are testing with all the options cranked up and 4xAA.
Anyways, I can't wait to see tests with 2x 4780X2 going! I also would have liked to see the 4780 (single) in all of the tests, but I figured the card would get roughly half of the performance of the new X2. No big deal.
The power consumption diagrams are making me realize why the 1000W+ PSUs exist. :) Good gravy, boy! A guy would have to pick up an extra shift or job just to pay the electric bill for the new cards coming out these days. Then again, most guys who buy this card likely live in their parent's basement. :p
Just joking, of course!
Game on, ATi! Nicely done.

This can't be a 1G version Derek. This has to be the 2G version everyone else has gotten. Can you confirm that?Nvidia... meet face. Age of Conan on this card is simply amazing. I think I'll trade in my 3850 512 for the X2 once it comes out. Something I said I wouldn't do for a while.

Kind of annoying you didn't include the ATI Radeon HD 4870 card in every test, as that's the most expensive one most people will care about. The $500+ stuff is ridiculous. The $299 card is a bit more worth reading about.The other thing is how you have to test at 2560x now just to show the biggest differences. Kinda shows that something like an 8800GT is still fine for 1680x and even 1920x for most games.

Let's see this is a preview about AMD's new high-end card that will directly compete with the 280. Of course most of us will never buy it, it doesn't mean it isn't important. There is already a review about the $300 card, it came out already with an indepth review.Every comparison has a nice graph and chart at the bottom showing performance at several different resolutions. If you are too lazy to THINK instead of just looking at the pretty color bars and seeing which one is longer, that's on you.
Really these complaints are just getting rediculous. If they failed to review the cheaper cards or only showed a single resolution/setting (cough...cough..(H)) then I could see your point. Fact of the matter is people shelling out >$500 for a graphics card probably DO have the screens with the resolutions in the bar graphs.

No offense to you, but it would seem to me that they were just a bit lazy on making the extra lines in the graph. I know that at Guru3D that they include different resolutions in the graphs.To me, it's not that I'm lazy, but it's a lot more difficult to compare different numbers across a range of cards and settings than it is to see which one is above and/or below others on a graph.

Put 2x 4870x2's in CF on an Intel X48 or X58 and you can kiss BOTH Nvidia's chipsets AND GPU's goodbye.Advantages:
Crossfire is fully supported on Intel chipsets with NO bridge chip required.
Crossfire won't be denied to function on Intel chipsets - the current bridge chip on Skulltrail has had 280 SLI denied by Nvidia, because they don't "feel" like enabling it.
Dual screens on Crossfire? No problem. Crossfire doesn't artificially limit dual screen use to just their workstation cards like Quadro.
4870x2 is already managing to beat SLI 280's in some places. Driver improvements will only make it a stronger beating in the future.
Don't you want a company that is committed to working WITH Intel, where it makes sense, rather than fighting them?
Support for DX 10.1 "just in case" it should end up enabled in some games.
Can you possibly imagine what the R800 is going to do? People should be considering the 4870x2 over the 280 and Crossfire of 280 SLI without a doubt. High res gaming has never looked so good.

Uh, multiple monitors are really important to a lot of people, I know it is to me, rendering SLI pointlessGriswold - Monday, July 14, 2008 - link
So, AMD needs to bring their drivers to the point where all games of the past benefit from multi-GPU? Are you sure we need to play 5-10 years old games (assuming they even run on todays systems) at 5000fps just to prove a point? :P
