Re: Pentium M is currently available up to 2.26 Ghz. That's not good news for Intel. Dothan is a purpose designed notebook part in which some serious compromises were made to save power. It has 1/4 the register space, isn't 64-bit, and has had its floating point performance crippled to reduce power use. It's rated at 27w "typical" at 2.26ghz. The Turion is a "no compromise" part with 4 times the power hungry register space, is a true 64-bit part, and has a full power (in both senses of the word) floating point unit. It's rated at 25w "typical" at 2.2ghz. Both 90nm parts. Intel has said that it had to drop 64-bit capabilities from Dothan's faminly to save power: One of the key differences between the chips is that Yonah will not include 64-bit processing. Mooly Eden, vice president of Intel's mobility group, has said that adding that functionality boosts power consumption. news.zdnet.com Dothan also has a power saving, but limited, I/O capability. The power saving compromises in Dothan lead to some serious performance limitations - and it still don't save any power compared to Turion: investorshub.com
