[hardocp] HD4800 Series Power Draw

post #1 of 33

We added power draw figures to our AMD Radeon HD 4800 series article today and, from what we have seen so far, some of you planning on a video card upgrade might want to add a new PSU to your shopping list as well.

All numbers above represent the same exact systems with simply a change in video cards. So you can see this hardly represents a "wimpy" system, although I am more than sure there are a few of you surpassing these numbers on your primary box.

As I've been saying, while the 4k series from ATI destroys nvidia in terms of price to performance, it falls down when it comes to power consumption.

EDIT: That's not entirely true, it only seems to fall down when it comes to power consumption against nvidia's 200 series, against the 9 series it seems pretty reasonable IMO.

125Mhz for 64W?or is the gddr5 memory the culprit?
from what i heard gddr5 was supposed to save energy,the way gddr4 cut down on the power consumption.

edit:good to see my old 6200tc up there too,32W monster

I thought you guys on OCN know it better.

Catalyst 8.6 does not use Power Play correct on HD4850's and HD4870's.
Cat 8.7 BETA already fixes this.


Do a Search on the net or wait for 8.7 final release if you don't believe...

If it is running at the same speed at the GDDR3 that you can expect less power consumption. But when you run it at 3-4 times the speed expect a nice boost in your consumption.

Power consumption seems to be the only draw back to the 4800 series. Nvdia actually did a really good job on their power usage.

Honestly, I have never cared about power consumption. I mean, we all OC and that in itself causes higher usage. If it were an HTPC and all passive of something, then yeah.

Ye definately. I mean, saving $6 a year (Well as I calculated, at $0.14 per kWh) on electricity if you run Crysis 24/7 will definately recoup the additional cost of the GTX280 compared to the HD4870 over what... about 60 years?
