Geforce 7800 GT will be indeed clocked at 400 MHz core and 1000 MHz memory and will feature 20 pipelines, no more no less. Memory of course has 256 bit interface resulting with total 32 GB/s of memory bandwidth. We are talking about 8 billion giga pixels a second fill rate capable card. It can calculate 700 million vertices a second.
Its PCIe only card and both 7800 GTX and GT are lacking its AGP brothers. It looks like that those cards will never be bridged and even today the fastest AGP cards comes from ATI and its called X850XT PE. Nvidia dont have Geforce series seven AGP to answer.
Releasing Geforce 7800GT will put some aditional preassure on ATI to have its R520 on the market and knowing the market we can expect more than one version of R520 card to match Nvidia high end offering.
