ATI Radeon R600

The long awaited and hugely anticipated ATI card is finally here. We have been given access to information and media documenting ATI's first DirectX10 graphics card. The technical specifications look promising, with some features never before seen on a GPU, making these cards innovative and one of a kind.

This article is designed to run through a little bit of the technical information without confusing the hell out of you. It is a short and sweet introduction into r600 and it's architecture and is meant to cover it in an understandable way.

The HD 2900 Series has a massive transistor count of 700 million which is slightly more than nVidia's G80 which has 681 million. The R600 die is manufactured on 80nm process technology, slightly lower than nVidia's G80 which uses 90nm. There are already plans to possibly reduce this to 65nm, which will mean lower power consumption & more importantly (for the overclockers) lower temperatures.

Interesting Extra Features

Before we launch into the technical jargon let's take a look at the extra features that ATI have implemented on the 2x00 cards...each card in the 2x00 series has both HDMI connectivity as well as 5.1 Audio.

A lot of people have been questioning the 5.1 Audio, but it really makes sense if you want to build a HTPC and makes it a all-in-one solution.

Clock Speed, numbers and more

Let's take a brief overview of the actual clock speeds of the 2x00 family. ATI have entered with three initial SKU's giving quite a breadth to their releases. The 2900XT is the card that tops the range, with the 2400 and 2600 filling in the gaps. I'm sure we will see more from AMD/ATI in the future, however.

Now some tech specs in an easy to read format:

I'm sure a lot of people have already read articles about these cards aswell as seeing the current benchmarks. I think we will see an improvement on benchmarks and general performance as new drivers are released.

Well you have the Apogee (very soon we hope) so I would go for a Laing D5 (reliability and flow), though some would say different :D

As it's your GPU too you want a PA 120.3 for a RAD, but your case is tiny so perhaps you could fit a 120.2 to the back of your case

GPU = MCW60 - would fit most newer cards too so you have options

For the res I reckon those tube res look very cool and you may just be able to squeeze one in. If not then Alphacool do a sweet mini-res :)

Tubing is your choice but myself I prefer 1/2" :D

wowo just saw hams post - bargain of the week!

Just measured up and there is no way I could fit a 24mm in the top of my case, only other solutions are a 24mm on the back or a 36mm on the top.

Ok this is what I have come up with so far, I am planning on mounting a 240mm rad on the back of my case and having a 120mm rad my free cd bays.

So I would need the following:

Not sure on a pump yet and if I should have a reservoir.

Comments welcome.

I second the MCW60 for GPU, very good block.

Also I wouldn't bother w/cing the NB.

You'll need a reservoir, I like the XPSC ones which fit in the 5.25" drive bays, have a blue LED as well.

For a res i recomend the alphacool cape coolex 25, check my rig gallery for pics.
It looks nice and hold a fair bit of liquid and i have it mounted on the roof of my case. :D
Theres my input for what its worth. lol.

It looks like something that women would play with :eek:

I am just looking for something small to sit inside my case ;)

15-05-2007, 18:31:43

Micro rez?

Swiftech MCres micro :)
BTW Kempez, Laing reports that 4.3% of DDCs are breaking. 4.3 is high statistically but chances are, if you buy a DDC you will be fine. D5s break as well, just a week ago on XS someone's D5 broke :) and the majority of people there use DDC. The only pumps I would call reliable are iwaki and panworld, and even then, they still have a chance of breaking. IanY, a crazy guy on XS, says "don't trust the pump" and sticks like 7 pumps into his computer...
Oh and try to get a thermochill if you can, they're most effective. A thermochill PA120.2 keeps water temps at almost the same temps as an MCR320 or Coolrad 32t, BUT has almost 1/2 the restriction. And of course, PA120.3 mops the floor.

GoldenTiger is what I'm looking at personally, I'm using an X-Qpack which is a small-form-factor... I modded it to use normal ATX boards, so while space is tight, I think I can fit it mostly inside :eek:, I think it's about as small as you'll get for a well-performing kit.

serialk11r is what I'm looking at personally, I'm using an X-Qpack which is a small-form-factor... I modded it to use normal ATX boards, so while space is tight, I think I can fit it mostly inside :eek:, I think it's about as small as you'll get for a well-performing kit.

That will not bring you good performance no matter how much you wish it will or how much you want to think it will. The radiator is simply too small.
