The graphics processors will be equipped with up to 512 MByte memory, support SLI and will be built in an 110nm process by TSMC. There is no reliable information on the potential of the cards at this time. However, manufacturers claim the 7800 will "clearly" outperform the 6800.
Sources mentioned that pricing of 7800 cards should be in line with the 6800 series and come in between $550 and $600 for the GTX model. But the almost traditional short supply of the new generation processors is likely to significantly inflate the price of 7800 cards.
