Re: R6450: too slow for Aero @ 1600 x 1200?

Wow 32bit ddr3 memory what a disaster. The ddr3 versions of the HD 6450 are pretty bad to begin with, and this one has only 1/3 the bandwidth of the reference ddr3 version, which should pretty much directly translate to only 1/3 the performance. Any half-current IGP will easily beat this (intel hd, ...

Re: Antec Kühler H20 620 & 920 CPU Water Coolers

There's also the issue the cpu will draw more power if it's hotter hence another reason why ambient temperature matters. I don't know how pronounced that effect is with the cpu in question though (but it could be easily measured). Given the relatively small ambient temperature difference (10 degrees...

Re: AMD A8-3850 Quad Core Desktop APU

ht4u did some undervolting (the only site I've seen doing this so far for Llano): http://ht4u.net/reviews/2011/amd_llano_apu_desktop_a8/index31.php They got the 1.4V sample to work stable at 1.16V (!).

Re: AMD Radeon HD 6570 & 6670 Budget GPUs

I think there's mostly two reasons for the lower power draw of the HD6670: - first, both cards seem to use the same voltage range - usually the lower clocked ones have lower voltage but for some reason this doesn't seem to be the case with the HD6570/HD6670 reference cards.

3x the performance of HD2000. Which would make it more like 2x that of HD3000. Though the comparison to HD2000 seems fair at least on the desktop, since intel only ships HD3000 with the high-end models (at least for the quad-core models, intel could easily ship the faster version if they wanted as a...
