Thinkpad X300 With SSD Performance Evaluation
Ninjakicks writes "Hard drives are typically one of the more significant performance bottlenecks in any system today. An evaluation of Lenovo's new ultra portable Thinkpad X300 notebook shows a fast solid state hard drive can
substantially improve the performance of a system. This is especially true of a low-end, low power processor and integrated graphics, in addition to reducing overall power consumption. Despite
its 1.2GHz CPU the Thinkpad X300 is actually able to outperform some desktop
replacement notebooks equipped with dual 7200RPM hard drives in RAID 0 in productivity benchmarks, and in data transfers. Interesting results, especially considering the X300's ultra portable form factor."
The article summary gave me an interesting idea. I have an old 1.5 GHz Pentium M notebook I was going to clean up and give to my folks. I'm wondering if replacing the existing HDD with a SSD would improve performance for it. It's a little old and clunky now, obviously.
This is true to an extent, but there are trade-offs that can't be made when using the computer. You may be able to turn off sections of a chip, but not nearly with the level of detail that you can by not adding transistors at the beginning. Trying to convert a fast, out-of-order CPU with many pipeline stages into a slower, in-order CPU with fewer pipeline stages at runtime would be effectively impossible. Additionally, the way that the chips are manufactured affects their speed: for example, fast transistors generally have higher leakage currents, so you have to compromise between high clock speeds and low static power.
