You will be able to find information about all Intel Processor on ark.intel.com
On the following PDF, on pag 47 is some information about power management on Ivy Brigde processors.
Thanks for you reply. Actually I have already checked the pages you mentioned. Unfortunately, there are no such information I need. I know they support Enhanced Speedstep technology. But what I need to know is how many frequency levels each processor supports.:<
Let me try to find some information for you. I will keep you post.
Thanks a lot.
I have done a lot of search.Actually I think such information may not be maintained by the company. It's not worthy.
The only possibility is that in some research papers, such information might be mentioned as they use different processors for their evaluation. And another reference I found is this :
In it there is an AMD six core Opterons processor that really supports quite some frequency levels. What I need is an CPU with at least 4 cores and better more frequency levels
