After seeing that the CrystalMark 2004R3 results were highest on my HTC Shift when using the default Balanced power plan (as opposed to the High Performance one), one of my favorite readers asked if I could "run the same tests on the TZ to see whether [I got] the same results."
I’ve posted benchmark results and a performance review of my Sony Vaio TZ170N ultraportable notebook before, but since I never considered the impact of power plans until yesterday and the request did come from a valued commenter, how could I resist?
Windows Vista Help defines the default power plans as follows:
- Balanced. Offers full performance when you need it and saves power during periods of inactivity.
- Power saver. Saves power by reducing system performance. This plan can help mobile PC users get the most from a single battery charge.
- High performance. Maximizes system performance and responsiveness. Mobile PC users might notice that their battery doesn’t last as long when using this plan.
The CrystalMark results below were yielded this afternoon on my 8-month-old TZ (1.06GHz Core 2 Duo U7500, 2GB RAM, 100GB 4200rpm HDD, Vista Business) running 83 processes after a system restart.
As with the HTC Shift, then, the Balanced power plan generally achieves the highest numbers.
What say you, Bruno?
