The original system sucked down 175W just at idle and peaked at 220W under hard use. The new system goes from 82W at idle to just over 90W under heavy load including the monitor - and it's faster. Not by a longshot, but marginally. It certainly multi-tasks better with the dual cores, but much more noticeable is the improvement in hard drive performance. The new drive technology absolutely smokes what the previous RAID could do. And the GMA graphics seem to perform on par with the aged GeForce.
Clearly, the new machine is no gaming or number crunching powerhouse. It is however plenty fast for everything else that I do, noticeably faster in many ways, and more importantly, something I have far less guilt about leaving on all day for streaming radio or tv.
Other highlights are virtually instantaneous sleep mode response going in and coming out, and ultra low power use in that state, plus the entire motherboard is barely larger than a CD case and requires only one fan for the chipset. The CPU heatsink is fanless, and now I don't even run a case fan, letting the power supply handle airflow instead.
Essentially I have built what many are now marketing as a 'Nettop' computer. I think I built mine better for less money however, spending $169 on everything.
Oh, and in case people think I'm silly for swapping out of one computer for one that is barely faster in some respects, the Asus motherboard was becoming increasingly unreliable and needed to go. I should have ditched it 2 years ago when the onboard RAID controller crapped out (which I replaced with a PCI card), but now even the power regulator is in the midst of going as well.
I know I could have gotten more speed for the money, but that wasn't the goal.
What OS did you have, and what OS do you have now?
I think you'll find your speed has improved more than your first impressions show. If you're not doing gaming or heavy graphics rendering, CPU is less important than most people think; what is far more important is quantity of RAM, which you've quadrupled. Also important is hard drive speed, the improvement of which you've already mentioned.
But I can literally put a hamster wheel inside of mine. :P
I finally got a replacement Silenx fan for the noisy stock northbridge fan today, and now unless it is absolutely dead quiet in the house, I can't hear anything from it. It's even quieter than our laptop.
Just out of curiosity, and because the cable/modem service was restored days before the power company restored the electric (service was out for 10 days, 12 hours!), I connected one laptop computer's power to a spare car battery (12 volts) with an inline fuse of 1 amp, pulled the laptop's on board battery and booted up. The 1 amp fuse lasted about 15 seconds before popping. I think the pcmcia wireless card was the last straw. I changed the dead fuse for a 1.5 amp and tried again with success. The current draw for that laptop, with wireless network card, is between 1 and 1.5 amperes. The car battery was actually 13.2 volts with no load. At 1.5 amperes that'd be 19.8 watts. So that laptop is somewhere under 20 watts.
Toshiba Satellite, 40GB, 96 MB, PIII, 133mhz. It's OK, I don't type fast enough to need more speed than that.
Oh! The OS is Win98SE, and that's only because the older OS don't support USB.
I forgot to mention this earlier, but over the summer I bought a new Dell Inspiron laptop with a Core 2 Duo processor. It uses ~ 50 or 60 watts total. I stopped using my Pentium 4 desktop with a 22" CRT monitor. I think that system used 600 - 800 watts total. I'm using about 1/10th of the energy as I was before.
