    Well they aren't really interchangeable technologies so a direct comparison isn't realistic but what I'm seeing is that Mobile based LPDDR2 is more inline with PC based SDRAM or DDR in terms of speeds. They are coming out with faster products, Samsung ow boasts some new chips that "deliver a data transmission speed of 1,066Mbps, which is more than double that of today's MDDR, which operates between 333 to 400Mbps."

    That is still significantly lower than true DDR2 which starts on the low end at 3200Mbps
