Power Consumption

The 4870 X2 is an incredible power hog. Yes, it does perform well. Yes it costs a bit less than two 4870 cards. But will we be able to afford the energy bill?

Idle Power

Load Power

In both idle and load power the 4870 X2 is near the bottom of our chart. The only thing more inane than the 4870 X2 is plugging two of them into one system. Keep in mind that this power measurement is taken running a 3dmark pixel shader test using almost no other resources. In actual game play power draw is much higher as the CPU, memory, and hard drive can come under load at the same time.

Welcome to the kilowatt era. We've been telling you these huge power supplies weren't that necessary until this generation, and we absolutely mean it. If you are thinking about a multi GPU solution involving the latest hardware you are going to want something upwards of 1KW. If you want GTX 280 SLI or 4870 X2 CrossFire you'll want to head on up to the 1200W deparment.

Oh, and, don't forget to turn it off when you aren't gaming.

    Buying a high end video card has little to no effect on the price of gasoline, seeing as very few power plants run off of oil. And are you relating electicity usage to forest fires and floods which are all natural disasters, and have been happening for milleniums? Look at what scientists are saying, and realize temperatures were actually warmer in the 1980's then they are now, and that plants even flourish with more CO2 in the atmosphere because that is what they use to make oxygen.

    Whatever makes you sleep better at night. Your approach is as if energy, despite how it is produced or distributed is an endless commodity. Where as, I am trying to take a more conservative approach towards the ideal that energy is a valuable resource because of the ways we import it and produce it. Now if energy was made via solar or wind, I would loosen up a bit with my energy spending habits because that it would then be renewable energy. I'm just saying, don't feed the pig if it's already over weight. Eventually that pig will not be able to walk, and the meat with spoil. We as a country need to completely change the way we think about our energy spending habits. If we buy these power hog cards and create a viable market for Nvidia and AMD to invest in year after year. The exuberant careless energy spending cycle continues... We are therefore feeding that pig until it will eventually collapse. WAKE UP AND SMELL THE NEWS PEOPLE!! Global warming is not even debatable anymore! It is a very real threat towards our existence as a people. I am done with this childish debate and I'm sure all of you will be happy I leave the board, but don't say you weren't all warned. Reply

    I guess SidePort will become useful on 4-way plus... in much the same way as 2 or more hypertransport links in opteron 4 and 8 way CPUs scale.

    So if you have 4 GPUs, the sideports could connect diagonal corners to reduce latency the two-hop latency and increase bandwidth.

    How the heck did you not include the 9800GX2 in your testing; I mean, that's Nvidia's only comprable card. And you said yourself it outperforms the GTX 280. When you factor in that it only cost 285 dollars on newegg it's a great buy. I'm actually amazed and sincerely confused as to why that card wasn't included in this review. Big mistake anandtech; not a small oversight but a complete disregard for common sense. Reply

    Usually, NDA dates are known well in advance for the latest and greatest tech. That means that many people are excited and looking forward to insight on release day.

    I was happy to see the 4870 X2 posted when I opened the site. I was even happier to see the authors of the review were Anand and Derek. This to me usually means a well-thought out unbiased article that would have unique industry insights.

    The article seemed rushed, incomplete, and unbalanced. What a disappointment! ATI released the current performance king in the 4870 X2, a mid-level 4850 X2, AND refreshed the 4870 and 4850 by doubling the RAM!

    So much time and effort was wasted in the article whining about AMD/ATI not using the Sideport that driver versions and system specs weren't even included.

    This post probably sounds like a broken record now that I'm number 70 something giving feedback that is not very positive. I just want this site to stay the best and I felt I owed it to you Anand and Derek to try and push you to do better. Thanks for all the great work that you have done over the years.

    I loved the article and well it shows that the new king of cards is the 4870X2, however; I think your doing a bit of extra work for a benchmark nobody will use. AOC is tanking hard, not sure if you guys are aware of that games overall lack of integrity. Since AOC is not going to be a well played or viewed game, why use that as a benchmark standard? I mean we won't care one bit about it sooner or later because the game is in it's death stages.

    Just a heads up on that. I think taking the AOC benchmark out of future reviews will be advised. Stick to what we know best and what stresses the hardware the most like Crysis etc. AOC for heavens sake doesn't even support DX10 yet.

    While I dont play AoC or plan on doing so, you just showed what a foolish idiot you are by claiming its soon demise. It has been the fastest selling MMO launch in history, I think "some" people will stick to it and even more will return when the content problem has been solved. Just because you dont like it, doesnt mean its not a good benchmark.

    I mean, I couldnt care less about all these "quake wars" and "ssassins creeds" that are, in my opinion, played by dumbass kids such as you, but hell, I wont complain about them being used as a benchmark.

    This article is a way to negative for AMD/ATIs cards. This looks like the reviewer hate ATI, dunno why

    First the negative article about 790GX-chipset, now this :(
