Where Lenovo has made improvements is with the Intel processors. The ThinkPad X301 offers a pair of not-yet-released Intel ultra-low volt processors that the PC vendor lists as the U9300, which has a clock speed of 1.2GHz, and the U9400, which as a clock speed of 1.4GHz. The two chips have 6MB of L2 cache and a 1066MHz front side bus.

In addition to the new processors, the Lenovo X301 will support DDR3 (double data rate 3) memory, which consumes less power and is faster than standard DDR2 memory

The other significant improvement to the ThinkPad X301 is its data storage capacity. While the original X300 offered a 64GB SSD, the X301 offers a choice of either an 80GB or 128 GB SSD.

Other improvements include DisplayPort and VGA video ports to support multiple displays. The X300 and X301 offer the option of a ultra-thin optical DVD burner that measures 7 millimeters.

The Lenovo X301 is available Aug. 26 for a starting price of $2,599. The 128GB SSD option will be available in September.
