ATi has shown off their PCI Express cards on the IDF just like NVIDIA did.
However of more interest was that it appears that ATI’s future high end part R420 made a small appearance. According to Tweakers.net, in a short part discussing the GDDR-3 graphics memory, which currently has speeds in the range of 500 - 700MHz (1 - 1.4GHz effective) ATI demonstrated a demo of the upcoming, DirectX9 heavy title, Colin McRae Rally 4 on R420, which was quoted as running at 2 - 3 time faster than present DirectX9 capable hardware. We contacted ATI to verify if this was R420 and they stated that they had demonstrated the title running on their future "Next Generation Hardware" which is as good an confirmation of this being R420 as you can get.
