Bjorn3D posted a review on the PowerColor X1650 PRO Video Card
The card I have today is a PowerColor X1650 PRO. It's not a high-end product, more like a middle class GPU with newer / lower price tag. Just as X1600 XT it's got the same pipeline configuration, 10 MHz higher core clock / memory and is manufactured using 80 nanometer process. No GDDR4 that we've seen on X1950 although it's technically possible. This RV535 uses 128-bit GDDR3 modules and supports the same technology back from Q1 2006. I will reveal more details as you read this article.PowerColor X1650 PRO Video Card Review
