ATI Radeon HD 3870 & 3850: A Return to Competition

Power Consumption
Dramatically improved is the Radeon HD 3800's power consumption over its predecessor, for obvious reasons. Despite being on a smaller manufacturing process however, the Radeon HD 3870 consumes slightly more power than the GeForce 8800 GT under load. At idle however, the 3800's smaller manufacturing process and new PowerPlay features give it the definite advantage. HTPC users will really appreciate that aspect of the Radeon HD 3800 series power consumption.
Moving to load power use, the difference between the new NVIDIA and AMD offerings is negligible. When you include the fact that the 8800 GT is faster, the Radeon HD 3870 actually has worse performance-per-watt than the competition. Under normal usage (e.g. not in a super hot case), both the 3870 and 3850 ran very quiet. We didn't have time to test how the coolers behaved under high heat conditions.

I don't see a noise slide...But actually, Anand, noise may be a deciding factor for me. I'd really like to know what the cards sound like vs. the GT8800, particularly the 3870, if you guys could come back to it.

What about testing with updated drivers? I understand that the HIS HD3870 cards are shipping with catalyst 8.43 drivers.Comdrpopnfresh - Thursday, November 15, 2007 - link
How do you guys decide the intermediate slopes of the graphs between them? Some of them look like cubic regressions...Bram van der Heijden - Thursday, November 15, 2007 - link
Just one thing i want to add.I think the last year AMD is really screwing up... dunno what there doing, but they aren't able to beat Intel, they aren't able to beat nVidia. Something went totally wrong over there. Marketing, Financial, Corporate launching strategies whatever... their screwing up.

Anand,How about the image quality? Some reviews claim its marginally better on the ati card than the 8800gt. Whats your take?

Best Anand, and other readers.I find it startling to see you making an assumption that's already a fact: "The Radeon HD 3870 becomes even more attractive the more expensive the 8800 GT is and the opposite is true the cheaper it gets; if the 8800 GT 512MB was available at $219, then the 3870 doesn't stand a chance."
I'm allready able to order Club3D 8800GT's 512MB for 208,- EURO's and even XFX's for about 212,45 EURO's... so thats even less in dollars. CLub3D is a company that builds good quality reference cards, so no suprises afterwards and XFX you all know.
So... for such a good site as Anand's i find it a bit strange you are not aware of this, and living by the quote stated above... this allready blows away the 3870... though luck again AMD.
Anyone interested in these cards haha, check out BEE-CT

There are rumors that in my country the ATI 3850 256MB version will cost 140€.160€ for the 512MB and around 200€ for the 3870.
So this is in line with what you say.
(all values have VAT)
About the good luck, I think even with the slightly slower card the DX10.1 capabilities will be a selling point.
Just ask the guys that bought the faster X800 over the 6800 and now can’t play some SM3 games.

One Euro is worth about 1.46 USD these days, no?So the 208 Euro card would cost about 304 USD, right?

Hmmm. back to school...That would mean 208/1.46 = 142 something...

but it's not like that... damn.. ur right... that's pretty expensive...I was wrong... sry.
