The X1600 didn’t match up to the nVidia 7600GT very favourably.  HIS took the already increased GPU speed and pushed it up even further.  HotHardware puts it onto the test bench to find out if they have managed to unseat nVidia’s current best value card.
‘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.’
