Not really Ryzen 2 (regardless of how it is marketed)... just a refresh of Zen 1 with some silicon bugfixes if we are lucky.

Zen2 is mostly likely 2019 and on 7nm.

Well, it is an improvement (from 14nm to 12) and they are getting better clock rates.

I expect that the prices will be better too.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I hope they fix the BMI2 bug.

Not sure why people are worried about the lame BMI numbers.
Don't compile for BMI, and the things roar like a rocket.

My thought exactly.
