"What do you think of AGP 8X specifications calling for 512 MBit/sec sustained data transfer from memory controller with burst rates of 2.1 GBit/sec. I wonder how fast one has to clock DDR memory to get decent Quake numbers with AGP 8X video boards." What do I think? I think you need to learn how to read, what is "bit", and how to get "bytes per second". I think you need to read the spec again and comprehend that the AGP-8 is an octal-pumped 66MHz 32-bit connection, with means 533MHz data rate, times 4 bytes, = 2.1GBytes per second _peak_ bandwidth. Which accidentally is equal to an ordinary 266-MHz single-channel DDRAM. Feeling better now? - Ali
