Merom vs. Yonah

[OC_A64]

Erm, no

Merom is quicker, uses less power and gives off less heat than Yonah. Yonah is only a few % quicker than a equiv X2 and Merom is much much much quicker 20-60%.

Erm no. I've benched X2's and Yonah's. Yonah IS a LOT faster than X2 at the same clockspeed - 20-25% I'd say.
Merom's give off more heat than Yonah's but use a little less power afaik.. They DO run a touch hotter at the same clockspeed, but don't need to run as fast to be as quick.
