What's new in the MTECH M860TU and the M570TU? Plenty. The most important feature to the customer is the new lower watt usage of the Intel Montevina CPU's. In some platforms it is now reduced to a mere 25W. The other really significant improvement is the system RAM is now DDR3 as compared to other laptops that use DDR2.

What is DDR3?

In electronic engineering, DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is a random access memory technology used for high speed storage of the working data of a computer or other digital electronic device.
DDR3 is part of the SDRAM family of technologies and is one of the many DRAM (dynamic random access memory) implementations. DDR3 SDRAM is an improvement over its predecessor, DDR2 SDRAM.
The primary benefit of DDR3 is the ability to run its I/O bus at four times the speed of the memory cells it contains, thus enabling faster bus speeds and higher peak throughput than earlier memory technologies.DDR3 memory promises a power consumption reduction of 30% compared to current commercial DDR2 modules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V.
