VIA's C3 Hits 1 GHz

Heat Down! Intel, AMD And VIA In Detail

I am not going to start a general discussion about the processors that are currently available. Instead, we will take a look at the thermal and electrical data of the common models - which is what is most important with respect to VIA's new C3:

Intel Celeron0.18 µmCoppermine1.75 V1100 MHz33 W
Intel Celeron0.13 µmTualatin1.5 V1400 MHz35 W
Intel Celeron0.18 µmWillamette1.55 V1700 MHz64 W
Intel Pentium III0.13 µmTualatin1.45 V1400 MHz31 W
Intel Pentium 40.18 µmWillamette1.75 V2000 MHz75 W
Intel Pentium 40.13 µmNorthwood1.5 V2533 MHz59 W
AMD Duron0.18 µmMorgan1.75 V1300 MHz60 W
AMD Athlon0.18 µmThunderbird1.75 V1400 MHz72 W
AMD Athlon XP0.18 µmPalomino1.75 V1733 MHz(2100+)73 W
VIA C30.13 µmEzra-T1.35 V1000 MHz12 W

The majority of processors sold currently run at least 1.2 GHz, but hardly anybody takes the time to look at what's behind the clock speed. VIA's C3 at 1 GHz comes with a maximum heat dissipation of as little at 12 Watts.

Here's some background on this number: 12 Watts is used by hard drives running on idle, energy-saving bulbs and portable radios or CD players. In contrast, the 70 Watts of a Pentium 4 or Athlon XP are enough to illuminate a small room, run a huge ventilator or even power a small television! Did you ever notice your workroom getting warmer in winter after working with a computer for several hours?

What if I told you that processors produce more heat per square inch than a hot plate, going back since the Pentium II? Yes, it's true: Modern processors are the most advanced heating systems around. Think about computer cases that are specifically built to heat up the surrounding area... but let's get back on topic. It's time to stop this waste of energy - one way or the other. VIA went the obvious way and reduced the power output.
