Radeon Mobility X1600 Not sure this is the correct place for this: Mods feel free to move it! Given that Apple seem to favour ATI chips for their high-end laptops I think that this is quite an interesting announcement. We may well see this chip in future PowerBooks. What is really interesting about this chip is that is supports Avivo. What is so interesting about Avivo? Avivo supports hardware H.264 decode acceleration. This could mean that next-generation PowerBooks can decode full 1080p HD content. Probably at under 50% CPU usage.
