Powercolor HD3850 Extreme PCS - AMD 3850 Performance explored

Overclocking and Power Consumption


Overclocking on the Powercolor HD3850 was performed using the excellent RivaTuner v2.06. A test run of 3DMark06 was performed after the overclock to verify stability and also if the OC was worth the time.

Note that no hard or soft mods were performed on the card apart from setting the higher clocks.


Here's what happened:


Not a bad overclock of .786/1982. I expect given time and some more mature driver that this card is capable of more as the cooler certainly keeps the card chilly.


A small rise in the 3DMark score shows that the overclock was worth it!

Power consumption

To get the power consumption of the cards listed I booted the PC with a GPU that takes up a negligible amount of power and recorded the power draw at the plug. I then compared this to the output of the exact same system with each card in turn at idle and full 100% load using RTHDRIBL.

Whilst this is not 100% accurate, it's a good measure of system power consumption.

power consumption

As we can see, the Powercolor HD3850 is very good on power consumption, easily lower than the power hungry 8800GTX and not doing too badly compared to the 8600GT, beating it at peak load power consumption.

Nice review Kemp. Performance was a little underwhelming but it all depends on the price point really. I think on the first page hard should be harm.Quote

Cheers mate. Performance was pretty damn good if you ask me, £135 for a card that nearly performs as well as an 8800GT?Quote

Nice review there, I really thought I would have to be canceling my 8800gt order! But not quite. I've never had an Ati card, but I take it the price will be around £130 and up for pre oc'ed cards. Is the powercolor a reasonably middle of the road brand for Ati?

The cooler looks pretty decent, found a link to manufactures of them:


Nice one Quote
