Re: AMD Radeon HD 6570 & 6670 Budget GPUs

I find the differences in video quality interesting.

Did you compare it to a software rendered frame?

btw Ati drivers have a "smooth video" check-box that disables post-processing features according to load.

Optical mice probably have more complicated, advanced and powerful chips inside, so they can process the image. Ball mice on the other hand only need to process the "yes" and "no" coming from the sensor behind the wheel. So I think the "majority" of the EMF is coming from the chips. You could try to...

Thank you for posting the results.

At 106W to 180W AC the seasonic seems to be 84.5% efficient.
So this PSU could be working at 120*84.5/111=91.4%. Too many unknown variables to be sure though.

Anandtech is the best tech site out there but their power consumption numbers are always way off. They say 5850 uses 86W less power than 5870 under load. I really doubt that. That would be about 1/2 of a 5870. We will have to wait for xbitlabs to measure the 5850 before we can compare power usage. ...
