HoloDust said: Not sure he did - 800MHz * 2bytes (16bits) * 4 modules = 6.4GByte/s. I think you calculated in Gbits: 800MHz * 16bit = 12.8Gbits/s (*4 modules = 51.2Gbits/s = 6.4GBytes/s) I might be wrong though, not completely sure if this is correct calculus. |
I think the right maths is...
800Mhz (the clock) * 2 (bits/line, DDR have 2) * 16bits (bus width) * 4 (modules) = 102,400 Mbits/s = 12,800 MBytes/s = 12.8 GByte/s
