NVIDIA launched its Geforce 7 range this month -- the month after ATI finally stole a lead on the green company by launching its X1900 series. The X1900 launch was big for ATI as it gave it the kudos of the fastest card on the market and re-established ATI as a graphics force. NVIDIA’s new 7900 GTX is little more than an updated 7800 GTX 512MB. The principal difference is that the fabrication process has seen architecture shrunk from a 110nm process to 90nm. This makes the card more power efficient and means that clock speeds can be raised: the core clock us is up 100MHz to 650MHz though memory speed has dropped from 850MHz to 800MHz..
