PC Stats posted a PowerColor X1600 XT PCI Express Videocard review
The powerfull little Radeon X1600 XT VPU is built on TSMC's 90 nm manufacturing process, and contains 157 million transistors, slim by today's standards. The Radeon X1600 XT core has a total of 12 pixel pipelines and 5 vertex pipelines to keep the triangles flowing along smoothly. At stock settings, we're looking at a videocard core which runs along at about 587 MHz, with 256MB of GDDR3 memory clocked at 1.3GHz (effective: 693 MHz).PowerColor X1600 XT PCI Express Videocard Review
