Benchmarks "Earlier this week Apple released updated Mac Pros that use Intel's new Penryn processors. Also new is the fact that the standard Mac Pro configuration now comes with eight (instead of four) cores. Of course, what I've been wondering (as I sit here and think about getting a new Mac Pro) is how does the new standard eight-core Mac Pro perform compared to the old high-end Mac Pro? I've gathered Geekbench 2 results for both Mac Pros to find out."

That is an interesting perspective you put this into, but I'd say it still is bigger than zero, which is what you get when you shut off your computer.

This is also true for all the other millions of electric devices people keep running on stand-by for no other reason as to be able to switch it on without getting out of the armchair. Which might add another perspective to your's.

I actually have "normal" switches that don't leave devices in stand-by for other appliances in my house. I'm conscious about energy savings and this is more important than laziness not wanting to move one's ass to unplug the TV after watching television. Same for the radio, the modem, etc...

Actually, unless you use a power bar with a switch or unplug your electronics, then they are using almost as much power turned off as a laptop uses in sleep mode. Your pc has power running through it all the time, waiting for the signal that you pushed the button to power it on. Thats how we are able to have software power ups and power downs. Still, I wouldnt mind seeing some part of the OS being written to a semi permanent memory on the motherboard. It could just be flashed during updates then. Or if buggered, wiped from the bios and then you could boot completely off the HDD.

Who cares if it's not precise zero? It's close enough to zero that it has no measurable impact on the environment.

"Every little bit counts" is a mantra that might make people feel good, but it's not one that is sound from an engineering point of view. If something you do to save energy has no measurable impact, it doesn't matter, and no, the thought doesn't count.

Another bit of perspective for you. You use as much energy in the couple of minutes you wait for your laptop to boot as it takes to keep it in sleep mode for a couple of hours. If you factor in the high energy usage of bootup/shutdown sequences (thanks to hitting the disk so hard), you might not even come out ahead!

I, for one, do and maintain it is not equal to zero, which it should be.

Well, improve your measuring capabilities then. The switch to Becquerel from Curie was probably only a "feel-good" excercise, too. Or along other lines, setting the scale obviously dictates what leaves a measurable impact. Compared to the tons of kerosine dropped by a single airplane before every landing the fuel consumption of a SUV is neglible. It certainly has no measurable impact, don't you agree?

And so we go full circle. You know, this little argument of ours started because someone actually asked for improved boot-procedures?
