I bought a new Thinkpad T460s laptop from Lenevo online store. I ordered a Intel i7-6600U CPU at 3.4GHz processor, but they sent me a 2.8GHz processor. When I asked them they replied it is 3.4GHz but not showing due to power saving.
But I do not agree with their response. So Lenevo please provide me a valid answer. Thank you.

There is only one kind of i7-6600U processor. The CPU has a base frequency and uses TurboBoost to generate speeds up to 3.4 gHz. CPU documentation is not consistent on how this information is displayed. Here are the full specs:

Thnak you for the reply. Previosly I got the same reply from Lenevo online store.
But my concern is even when I am using 100% CPU, it is only 2.98GHz. Please find a acreen shot in the attachment. What that would mean?https://drive.google.com/open?id=0B2iC43qYsdcARU5TU2tqY1NBNFE

It is impossible to drive all the logical threads at the maximum speed. Even if you are running a burn-in utility to drive all the threads, there are tasks related to the operating system that won't drive a thread that fast. If you have a process that uses one thread, task manager will show 25% CPU usage plus the overhead
