Hmm, I picked up a Palit 8800GT about 6 months ago that came with a non reference cooler that was just RUBBISH (very loud, constantly on, no PWM), I replaced it with a nice zalman one in the end.
Anyway, it left kind of a bad taste in my mouth as far as Palit are concerned, nice to see their ATI side is looking good.

Was it one similar to this one on the 9600 GT Sonic we used in our £400 gaming PC? Linky: http://www.bit-tech.net/hardware/2008/06/11/building-a-400-gaming-pc/2

Any chance you can let me know how loud the card was?

The heatsink design is not a familiar one, but it combines a 70mm variable speed fan with an array of aluminium fins that are connected to a copper base via two nickel plated heatpipes. It's a dual slot design and for the most part the fan remains quiet, spinning slowly even under extended 3D load in games like Crysis.

I don't think it's as quiet as the HIS/Powercolor at idle, but at load it's easily quieter than the HIS and probably a dead heat with the Powercolor.

Hm... Is the reference design 4-phase or 2-phase? From the pictures of it it seems like it's a 4-phase design but there are a couple of websites which says the reference is a 2-phase design?
Quote Tim S 15th October 2008, 07:07
I am fairly sure that it is four phases with two 'fets per phase, but I will ask for confirmation again...

So...no "normal - analogue" TV out?
Svideo or Component?
Quote Frido 15th October 2008, 08:54
My guess is S-video, since Tim stated that there was no dongle with this card. (Just correct me if I'm wrong)
Quote Tim S 15th October 2008, 09:12
you can connect S-video directly to the card, but there's no Component (because of the lack of the dongle), but you can use one that you got with a previous purchase if you have one.

Ok, that's covered, now roll on the 4870's with good cooling.

Reference card have 2-phase power supply for GPU not four. It's uses uP6201 - Dual-Phase Synchronous-Rectified Buck Controller.
It's have two chokes per phase in parallel.
SONIC is with much better power supply (3-phase).

Thanks for signing up to post this information. I've also had confirmation back from AMD and the reference design is indeed two chokes per phase - I've updated the review to reflect this fact.
