HIS X1650 Pro IceQ Turbo
 

ATI's reference design specs the Radeon X1650 Pro's GPU speed at 600MHz, a full 100MHz faster than the X1600 Pro which runs at 500MHz. However, HIS took things a step further, and raised the GPU clock an additional 25MHz, to a default speed of 625MHz http://www.hothardware.com/viewartic...leid=900&cid=2
