AMD's Radeon HD 4870 X2 - Testing the Multi-GPU Waters

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?
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.

... but I find a response a bit cold.It's the fastest card for God sake!

it was pretty negative. there really isn't anything negative about this card. price and power consumption (the only arguably negative things about this card) are in line with anything nVidia would have had they made a product to compete against this.Finally - Tuesday, August 12, 2008 - link
And what is this?!"When you start pushing up over $450 and into multi-GPU solutions, you do have to be prepared for even more diminished returns on your investment, and the 4870 X2 is no exception."
Man! This is a bullshit card for bullshit buyers, sry I meant: ENTHUSIASTS... What the heck do you expect? Low power consumption and reasonable price-to-power-relations? I totally don't get it...
Isn't this the "We like power supplies only if they can assure us that they will kill the rain forest single-handedly" site?
Where is the bullshit, sry again: enthusiasm?

Is it just my eyes or did they actually read the following heading on page2?"NVIDIA Strikes Back"
*sound of a Vegas-style gambling automat turning out big coin*
If there was a prize for a totally out-of-order title... this would take rank 1 to 3...

You are right; got that perception, too...Although I would never buy a dualchip cardmonster like this one (save SLI or CF...) I actually love it how they manage to take an article about an AMD product and turn around till you don't know wheter it was about the new HD4870X2 or the lackluster 280...

In my opinion this review is way too negative. It is solutions like this that have caused Nvidia to drop prices and increase competition between the competitors. Its the best card money can buy for ffs.formulav8 - Tuesday, August 12, 2008 - link
Yeps, this is one of the worst reviews Anand himself has ever done. He continues to praise nVideo who just a month or 2 ago was charging $600 for their cards.Give credit where credit is do. He even harps on a sideport feature that doesn't mean much now and AMD says it didn't provide no real benefit even when it was enabled.
I've been a member of this site since 2000 and am dissappointed how bad the reviews here are getting especially when they have a biased tone to them.
Of course, this is only my opinion.

I think Anand's initial comments has to be viewed in the light of his conclusion:"I keep getting the impression that multi-GPU is great for marketing but not particularly important when it comes to actually investing R&D dollars into design. With every generation, especially from AMD, I expect to see a much more seamless use of multiple GPUs, but instead we're given the same old solution - we rely on software profiles to ensure that multiple GPUs work well in a system rather than having a hardware solution where two GPUs truly appear, behave and act as one to the software."
I wholeheartedly agree. The software profile solution has baffled me for years. Why are they messing about with this? It was supposed to be a temporary thing. Creating unique profiles for every game title is not feasible. At the very least give the developers an API that will help them do this themselves.
Instead of messing about with the power hungry sideport nonsense, AMD should have invested some R&D time on how to get rid of software profiles.

Probably because from a design perspective it works... And based on the benchmark results it works very well indeed. Additionally we know from the early days of SLI that not all games will respond well to all modes, so it seems to be that at a HW level the task of getting the card to automatically perform amazingly with multiple GPU's is going to be difficult to say the least (perhaps feautal?).EglsFly - Tuesday, August 12, 2008 - link
I agree!It is because of ATI/AMD's release of the 4000 series cards that Nvidia had to dramatically drop the price of its GPU's.
AMD brought great performance to the masses at an affordable price point. Here they up the ante with an even higher performing solution and what do we get in return from Anandtech? A biased review full of negativity that it looks like it was written by somebody from Nvidia.
