If every part of the I/O were inside the SoC, why would that be more expensive? Don't you think the internal busses of a 700 MHz processor can keep up with a 5 Gbps serial bus? 32 * 700 MHz is 22.4 GHz. Regardless, only the video has to run at particularly high rates. The rest of the peripherals are relatively low average rates with high burst rates. An SoC is only limited by it's memory band width. Why would the SoC be any more expensive? -- Rick
