AS THE R520 Radeon X1800XT and LE both comes with 512MB of RAM, Nvidia kind of had to do something about it. Nvidia decided to react with a 512MB version of its already existing Geforce 7800GTX. Till this point, only 256MB versions were available. We believe that Nvidia earned some money selling Geforce 7800GTX 256MB versions for $549 and earned some serous money on memory. ATI on the other hand wants and has to push with 512MB of very expensive memory.
Nvidia believes in availability and wants to send press samples shortly before the card is available but we suspect that this might happen shortly. It needs to make a new PCB in order to accommodate more memory chips and we don’t think that Nvidia will play with the card's clock. We are quite sure that GTX remains working at the original 430MHz core but there is some space for Nvidia to overclock the memory. We still don’t know whether that will take place or not.
Nvidia doesn’t plan to give up without a fight and we are sure that Nvidia plans to adjust the prices to put some additional pressure on Radeon X1800 and the rest of R520 generation.
