Amazing. ATI soon-to-be flagship having a length shorter than 8800GTS. Provided its accurate, of course.
Notice how the R600 power circuitry is much more tightly packed than 8800s...A sign that R600 uses less power?

I think most of the R600 driver issues are due to the tester not having used a fresh installation of Vista! 🙂
That sounds pretty optimistic, given other companies history with vista drivers, and having one person testing it having issues.
Ill wait for a real review outside of NDAs, because the size of the card and the subjective amount of noise the heatsink makes are both moot points on an engineering sample.

"HI there
This is indeed the case, the ATI cooler exhaust the heat effectively out of the case in comparison to the NVIDIA design.
Its now ran 3D Mark 2005 and 2006, I am pleased with the results."

You guys are mixing some information up.
First, the R600 doesn't have 320 stream shaders. It has 64 unified shaders that have up to a 5 op per cycle frequency. That means that if all the shaders operate at optimum frequency, you'll "effectively" have 320 shaders.
The problem is, if games and driver applications aren't programmed to implement the higher op per cycle, you're likely to never see them in action. A more realistic perspective is 2 ops per cycle, thus making the R600 shader power equivalent of an 8800GTX. Which is still good for the R600XT because it's $100-150 cheaper than the 8800GTX. Think of it this way. If drivers aren't meant to utilize multiple operations per clock on shaders, you'll see the 8800GTX destroy the R600XT and R650 in that department, by a large margin I might add, somewhere around 100%. But if applications utilize the stream shaders, you could see the R600 win by about 25% performance. (Only 25% because even though the 8800GTX has 128 unified shaders versus 320 stream shaders, the Nvidia core runs at a much higher speed)
Another mistake you guys are making is thinking about the XTX. I hate to break it to you guys but ATI isn't launching the R650/XTX in May.
They're pulling another 1800XT/1900XT bait/switch. They're going to release the R600XT only and at a $399 push. But every other range of the R600 chip is going to wait for the 65nm revision model which won't be out for another 2 months. The R600XT is merely to pull sales away from the 8800GTX/GTS, because it bests the GTS in every benchmark and hangs with the 8800GTX but it's $399. This is merely to save face and start putting some reputation on their table. Don't think about over-clocking the R600XT though. As sad as it is, it's the truth that the R600XT is quiet and "warm", but it puts out nearly 200w at full load at stock speeds. You wouldn't be able to over-clock it even the slightest without some massive cooling. The 65nm versions of these cards should be faster, cooler and quieter really.
They were supposed to can the R600XT but they didn't want the bad PR from another push back. They just decided to push out the R600XT to save face and they're going to release the R650 as soon as the revision is complete.
