I would like to know how much watts used for non-AVX loads at both cpu speeds: maximum turbo, and without turbo (set cpu max in windows power options to 99%)

to do non-AVX stress, you need an old version of prime95, like this:

(the source of the above link is the official site: http://www.mersenneforum.org/showthread.php?t=12155 )

You need also 'hwinfo' to see "cpu package" watt reading.

would really appreciate this, thanks :)
