Computer hardware

I built a new computer last week to replace my old one. My computer is running 24h a days, so I focused on low power hardware with good peak performance. Next to a low-power computer I have a computer built for performance (gaming and heavy development). Because the low power computer is always on, I tend to use it for some quick development as well. Switch on the display, change a few lines of Bluefish code and compile.

The old low power computer, an Athlon X2 2700MHz, idles at about 55W. Compiling Bluefish takes 43s. The performance computer, a Core2 duo 3.3GHz idles at about 83W. Compiling Bluefish takes 25s.

The new computer, a Haswell core i5 3.2Ghz with turbo to 3.6GHz idles at about 20W (if I stop a few services I can get it to 16W!). Compiling Bluefish takes 11s. This basically means I can replace two computers at once! It’s much lower power than my low-power computer, but much faster than my performance computer!

For those interested in building a low-power/high-performance computer the build specs:

  • Intel Core i5 4570
  • ASRock B85M Pro4 (see this review for low power haswell boards, text in Dutch, but the graphs speak for themselves)
  • WD Red SATA 6 Gb/s WD30EFRX, 3TB
  • 16Gb Crucial Ballistix Sport DDR3-1600
  • be quiet! Pure Power L8 300W (see this and this review for power supplies that are efficient in the very low power ranges.)
  • Crucial M500 2,5″ 240GB
  • Gelid Solutions Tranquillo Rev.2
  • Fractal Design Core 1000 USB 3.0
