Re: Fashion Wearable

I'm running a k6-2+ 500 (2 volt) at 400mhz, and 1.9V core.  I can just
get away without a fan, and I'm using quite a small heatsink.   The
350mhz versions of this chip run at 1.5V, and uses 5.6w at full speed.  
This table is from the k6-2+ 450 datasheet (low power version)

Core voltage            operating frequ         Active power
1.7v                    450-200mhz              8.7-4.9w
1.6v                    400-200mhz              6.9-4.2w
1.5v                    350-200mhz              5.6-3.7w
1.4v                    300-200mhz              4.3-2.95w       

The normal k6-2+ 500 is 13.9w @ 2V 100% cpu use, 4.5w in idle mode.  I
think it works out to less than  @ 400mhz.  (66mhz bus speed, 6x
multiplier - the m/b I'm using can only do 66mhz bus)

The k6-2+ also has 128kb of L2 cache built into the chip, which speeds
things up a lot.
