ATI HD 3800 Review Thread

[STaRGaZeR]

Me too!

When I tested HD2900 CF setup set @777/980 +my X2 6000+@3500Mhz 1.5V power draw from socket was reaching 720W during 3DMark06 run!!
Now with this pair of HD3870 set @877/1311 all the rest identical I can't even push over 450W!!

That is huge improvement under load, but idle is amazing too! It's better (lower) with two cards than what it was with ONE HD2900Pro(XT) !

Hehe I´m also monitoring power consumption with my Gigabyte Odin (yes I know, weird system, and inaccurate) but my system with the 2900XT idles at 150W, with an X800 at 100W, and with 3870 100W too! Impressive. And loaded, 2900XT 330W, 3870 only 235W!! More impressive. In a few days I will test 3870 CF.

Am I in the right place, sounds like I would be lost in XtremePowerSavingSystems.com?

There are many ways to be extreme dude

Then why were soooo many people ing about the R600 power draw here?

Soooo, basically, in performance wise

8800GT > 3870 > 3850 > 8800Ultra > 8800GTX > 2900XT > 8800GTS

No.

8800Ultra>8800GTX>8800GT>3870>2900XT>8800GTS>3850

in single card set ups. Xfire gives more benefit than SLI atm, however, and shifts that list more towards ATI's benefit in multi GPU set ups.

I'll agree with that for the most part, except for your last comment.

Scaling looks pretty good from the Radeon HD 3850, however it's still not as good as what NVIDIA is able to achieve with the 8800 GT. NVIDIA consistently achieves about 11% better scaling from one to two GPUs than AMD.

I could be wrong. I was relying on the following:

http://www.expreview.com/review/2007...2778d7055.html

which is more extensive than the Anand testing and seems to show the CFed 3870s more competitive against the SLI GTs than the single card comparison. Drivers and i780 could certainly change that though.

No.

8800Ultra>8800GTX>8800GT>3870>2900XT>8800GTS>3850

AA8x is faster on 3870. =>

AA8xAF16x

3870>8800GT

The Anand comparison is worthless, with Catalyst 7.10.
