Thoughts on power draw equating product quality.

Hey everyone.

I've been following the graphics wars on and off with a fair amount of interest over the last year.

I've noticed AMD seems to be putting out some parts that have crazy-low power requirements compared to competitive parts.

Is the cost of power to performance an indication of good engineering in your mind? I guess I tend to equate lower power with lower thermals, which often ties to higher overclockability.

I have a few tentative theories about why AMD's lowering of power usage may be going on (and would be interested in hearing other folks' speculation).

Firstly, if you're going to start slapping GPU's on die with CPUs (as AMD has suggested in the past), then getting the wattage down is probably vital to keeping heat down as well. So, in a sense, I wonder if this is them "prepping" to make that move.

The whole "green" thing has been increasingly popular, but considering the development cycles for GPUs, I doubt the development was done on the 4670 parts with the tree huggers in mind. (What do you think their motivation was for the power to performance ratio? To simply kick ass? Where will this lead?)

Oddly, despite the pleasing looking power numbers, there is a VERY obvious dearth of low profile 4600 and 4800 parts in the US market. None, in fact (and I've been looking for a few hours most weeks).

It seems counter-intuitive that 4600 and 4800 series cards wouldn't be out in droves in low profile, passively cooled configurations for tiny living room boxes across the country. Currently, the only offerings for low profile cards that I'd also feel comfortable gaming on are NVIDIA parts, and the 9600 GT and better require an additional 6 pin power connector.

Rampant speculation and theories welcomed.

Actually, at equivalent performance levels the ATi cards are about the same as their nVidia counterparts. For example, the 4870 pulls as much power under load as the GTX 260. But the GTX 260 has two advantages: it has a more efficient cooler (quieter & cools better) and nVidia has managed to create a much better "low power" profile for their top end cards so they draw considerably less power when idle.

ah, so the higher end are higher power draw? I haven't looked into power draw on the higher ones much. I've been doing lots of research for some folks on "mainstream" cards.

Perhaps the higher power draw at higher end would indicate worse scaling of the core technology :eek:
