I think this is pretty relevant. XO-1.75 is roughly similar CPU-performance wise to a XO-1.5, will be a bit faster with a fully optimized toolchain and compiler, which we don't have for 11.3.0 (but plan to have for 12.1.0). The solid state disk storage is much faster on XO-1.75. The GPU is currently slower, but potentially a bit faster. You can think about it as a bit faster than XO-1.5, with much lower power draw, and lower price. As any generalization, it's only valid if you don't look into the details... cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- Software Architect - OLPC - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
