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

General Performance at 2560x1600
We've already established that in games with CrossFire support, the Radeon HD 4870 X2 is the grand poobah of gaming performance. Along with such a title comes a general requirement: if you're dropping over $500 on a graphics card on a somewhat regular basis, you had better have a good monitor - one of many 30" displays comes to mind. Without a monitor that can handle 2560x1600, especially with 2x 4870 X2 cards in CrossFire, all that hard earned money spent on graphics hardware is just wasted.
Since the target resolution here is 2560 x 1600, let's see how the 4870 X2 stacks up in our suite of games at this resolution:
The 4870 X2 holds its own against its major competition from NVIDIA, the GTX 260 SLI, in 4 of our 7 benchmarks, while the 4870 X2 CrossFire leads the pack in all but one game (Assassin's Creed). It is always tough to pick the games we want to test, as the games we pick end up deciding what we think of performance. We try to pick games that are both interesting to the community and/or show interesting performance differences between hardware. In this case, what we have here is a pretty good picture of the general case: the 4870 X2 and GTX 260 SLI are pretty well matched.
Of course, the GTX 260 SLI option is two cards which requires an NVIDIA motherboard. This puts it at a bit of a disadvantage to a single card solution that is platform agnostic. And we also have the fact that at the target resolution of 4870 X2 CrossFire AMD does have the most powerful option that fits into two slots. These are very important factors for AMD, but as we've seen before 4-way solutions aren't the value option (you don't get the same return on your money as you might with other solutions even if you do get high performance).
Taking into account the price drops, we also see the single GPU arena looking very competitive with the GTX 260 and HD 4870 about on par. In these tests, the HD 4870 looks to have an advantage, but again we could add a few more benchmarks and see the GTX 260 do better. This is what we like to see: real competition. Of course, the tough question to answer here is whether or not the GTX 280 is worth 1.5x either the GTX 260 or the 4870.

Is anyone still waiting for ATI to get off their butts and fix/enhance their avivo encoder?Its incredibly fast but having the ability to encode high quality videos would be nice.
If ATI are not willing to develop it why dont they just open up the source code so that others can develop it?

For one, I haven't seen a 4870X2 for less than $600-650 and they don't exist now. Don't expect these to go for $550 for a while. You should print what they are being SOLD for at the time of the article.GTX260 pricing (check newegg) is off also. You can get one for $245 and it's an OC Edition (MSI)! They have quite a few at $269 retail. So where the heck do you get $300? Again quit printing suggested retail prices (or whatever they are) and PRINT ACTUAL PRICING! In the case of your GXT260 SLI price that would drop it $110 and they are both overclocked!
GTX280 isn't $450. Newegg has them for $399 if you want the cheapest, and most are $410-429. Do you guys even check the pricing before putting up your stories? You do this every time.
You state this for AMD "At the same time, AMD's literally hot GPUs have seen their prices fall; the Radeon HD 4870 is now a $270 - $280 GPU, slightly down from $299 and the Radeon HD 4850 is a $170 - $180 card. These are very slight changes in price, but at least they are in the right direction."
But you conveniently leave out that Nvidia's cards don't run $450 (GTX280 your price) or $299 (GTX260 your price). These are FAR from reality. A suggested retail doesn't matter. What matters is WHAT I WILL PAY if I buy it today! These prices haven't changed in about a week so you've had plenty of time to faq check before printing. Also the 4870 is $250/259 if you want the cheapest at newegg. So you even got the ATI pricing wrong. Newegg has some 4870X2's listed at $559+ but they won't be that by the time their auto-price-upping machine gets done with them (still higher than the $550 you state...which won't happen for a month or more likely). They'll hit $600 next week before one even sells...LOL. You need to fix the prcing in the article to reflect REALITY.

I just bought a Sapphire 4870X2 from Newegg for $559 an hour ago so the pricing is correct. Obviously on launch day they are going to be sold out as people like me have been waiting for them for months now...the same was true of the 280GTXs as well. It will take a couple weeks before they become readily available and then the price will start coming down eventually to around $500.00.Aberforth - Tuesday, August 12, 2008 - link
I am studying business models of different tech companies - from the core architectures to marketing, it helps me to understand how these products actually sell, basically the crux of the tech industry.We've seen GTX 280, which was priced at $650 when it was released, but even after months of research NV comes up with a GPU that is just too large and bloated- redesign is what they actually do. Yet, it gets a good review and market hype. When you look at some of the early 260 reviews, they actually say "it's reasonably priced".
So these self proclaimed geeks write articles based on comparison- which is a childish thing to do. You cannot compare one design with another nor you can judge it's merits only looking at the performance factor. There cannot be one single outcome of a review, there are different types of customers with different requirements. So at the end of the review if someone favors either AMD or NV are biased. A unbiased review cannot contain suggestive material that hampers the customer's decision but instead it should contain information on how it affects customers with different requirements.

Thanx for that - good post.I have been thinking similar thoughts; but my ability to say it as you have done, was clouded by my own reaction of disgust at this shit-on-a-stick socalled report.
This site is seriously biased against AMD.
I used to think it was thorough testing - but issues found here, are not reported elsewhere, and are simply not experienced by users that post to forums. I expect config issues with new releases - but this site uses any excuse.
Anandtech BIAS is out of the bag.
I thought I was the only one seeing this; but I am glad to see general rejection of bullshit by many others.
Very unprofessional that we have no idea what 486-box you used to skew these results - YOUR RESULTS DON'T MATCH OTHER SITES - and they aren't shuffling dx9 and dx10 to fudge it all.
If you have to change the game midstream,
u r cheating.

I'm surprised that the 9800 GX2 wasn't included in the benchmarks...Seeing that the 4870 X2 is ATI's most powerful single card solution and as this article states the 9800 GX2 is still Nvidias's most powerful single card solution. Not to mention they are very similarly priced and they are both dual GPU cards...

The 9800GX2 would get smoked in higher resolutions with it's much lower bandwidth and smaller frame buffer. Anything above 1600x1200 especially with AA and the GX2 would choke. That's where the 4870x2 really shines is above those resolutions. That's why.Spacecomber - Tuesday, August 12, 2008 - link
I was wondering the same thing: why leave out nvidia's dual core card? I know that it is not as powerful as the 4870 GX2, but it is nvidia's most powerful single card solution. And, the pricing seems to make it a fairly competitive option. It is selling for less than $300, which positions it well against the 4870 single core card as well as the GTX 280.It's not a big deal, but it has struck me as odd that this card hasn't been included in recent video card reviews. I know that not every available card can be rounded up for benchmarking; however, I think this is one that many consumers would be interested in knowing about, especially if they are thinking of spending around $300 on a video card.

Mr. Anand Lal Shimpi:you have a writer working for you that has a bias towards a particular IHV. How do I know this? Because he makes it apparent in EVERY piece he writes. Derek Wilson, the constant pot-shots against ATi are pathetic. You are incapable of keeping your bias out of your articles, and therefore should not be writing. I will not read another Derek Wilson article again. In fact, I will not read another Anandtech article until something is done about this matter.
I'm not the only person aware of Mr. Wilson's bias, all of my tech enthusiast friends are aware and feel the same way. It is sad what has become of Anandtech in recent years. It used to be easy to trust Anandtech and take your writers' word on any issue, but no more. Derek Wilson is dragging this site's name through the mud.
Dismayed,

Keys also goes overboard to find trouble.And lack of followup articles - as promised - where are they? Trouble only reported here with 780G has not been followed up as mentioned it would be - since last May. But the damage was done. Do we believe it or no?
Credibility? nah.
Bias? haha
the ntel fanboys seem to like it - or employboys.
And the ultimate recently 16 pages of praise for non-existent theoretical 2yrs out larrabeee rehash trash. Preceded by - we don't know anything about it at all. as dictated by ntel bs div.
Biased much? haha
This is dangerous market influence. How far does this go? How long has this been happening?
Violating trust is pretty sad.
