PCI was 33Mhz @ 32-BIT register and has the data tansfer rate of 133MB/s AGP was clocked @ 66Mhz with trasnfer rate of twice as of PCI, so 266MB/s AGP2X =clock rate = 133Mhz, DTR= 532MB/s (Roughly) as it has capability to read on both rising and falling edges of signals. AGP 4X = 266X4 = 1064MB/s (or ~ 1GB/s), clock rated at 266Mhz AGP 8X = 266X8 ~ 2GB/s , clock rated at 533Mhz and so does PCI-E = 16X ~ 1Ghz Clock rate and DTR ~ 4.15Gb/s ~ means not equal, but equalivent. theoritically AGP8X was suppose to be twice as fast as AGP4X, but it isnt. __________________ Intel Core2Quad 2.66Ghz 12MB L2-Cache 4096MB DDR Kingston Hyper-X GigaByte GA-P35-DS3R XFX 9600GT AlphaDog Seagate 2 X 320GB SATA2 LG L246WH Flatron 24" Sony DVD-RW
