Sapphire HD3470 Power Consumption?

Hi Guys,

Anyone know the idle/load power consumption of the ATi HD 3470 card, and if possible more specifically the passive Sapphire model?

I've been searching for a couple of days with no luck!

Thanks.

And just after posting this I find the answer

HD 3470 25W - 25W

HD 3450 7W - 10W

the 3450 at 7-10W I think I have changed my mind as to which to buy!

Where did you find them?

Thanks

I think your 3470 numbers are a little misleading. You state them as 25w-25w. (min.-max.) I doubt this is true.

All the numbers posted anywhere I can find on the 3470, even on the link you provided, only shows the The official "peak power consumption" from the manufacturer which is 25W. Your post above makes it look like the card consumes 25W at idle as well as peak. I do not have proof that this is not true but I highly doubt it. From all the info on the net, until someone physically tests the power consumtion of the card, we can only state that the official "peak power consumption" from the manufacturer which is 25W. From what the 3450 and 3650 consumes at idle in test on the net, I'd "guess" the 3470 would also be in the 7 to 8 watt range at idle.

Now I'm sure actual power consumption of the 3470 will be higher than the 7W-10W of the 3450. How much more? I'm not sure, but I definitely would not write it off in favor of the 3450 from the current 3470 numbers posted on the net unless having the least amount of power consumption is your #1 priority.

The main benefit of the 3450 over the 3470 in my book is it's ability to be a low-profile card. The benefits of the 3470 over the 3450 in my book is the extra power to do better video post processing. Both having <25W peak power consumption make them both winners in my book.

Just my .02 cents.

Hi Southpaw, you are of course correct, my bad, I read the chart as 25W both ways, which was a stupid assumption

I wonder what the 3470s idle power draw is, anyone know?

Does anyone know if there any other HD3470 silent versions out there right now or in the near future besides the Sapphire?

Just a quick question further - Would the video post-processing abilities of the HD2400XT be just as good?

I thought I had read that the 3470 was exclusive to Sapphire. I think that may have been refering to the launch but still havent spotted any others yet.

Isnt the 3470 the same GPU but with DDR3?
