    I think in the UK the FZ11L is 64mb dedicated ram, the FZ11S is 128mb and the FZ11Z is 256mb. Sony state dedicated ram for the FZ11S and FZ11Z but not for the FZ11L, however going by the total memory available (831mb, 895mb and 1023mb respectivly) the FZ11L has 64mb less than the FZ11S. Thats how i see it anyway!

    well, the bandwidth is supposed to be 128 bit for the gt, only the gs and below are 64 bit. If sony is shipping it with 64 bit then its shipping us different chips which is misleading marketing which u could sue for ?

    ok so given that the cards are all 128bit what is the performance difference between the amount of memory? Would the 64mb card version be half as slow as the 128mb card when it come to games?
