The speed listed by the CPU is the stock clock speed. This is the highest speed the processor should maintain when not under load, provided it is not overheating.
 
The Maximum speed it lists is likely the highest speed that Turbo can apply to all cores (although that's just in this case). This speed will only be seen if there is a sufficient load on both cores of the 4510U, and only for the duration of the load.
 
The Speed by the utilization percentage is the highest speed of a single core, which it can go up to 3.1GHz. This speed is usually seen if there is more load on a single core than the others.
 
Turbo speeds depend on load, thermal headroom, and power draw headroom.

actually, from top to down, left to right I'd say:
- base frequency of the CPU
- overclock frequency of the CPU (current CPU frequency)
- maximum (boost) frequency of the CPU

We mostly know what to expect from intel, but zen is probably still one of the biggest question marks.
 
Whatever you do, at this time i recommend against anything AMD that is pre-zen, we'll wait and see for the benchmarks if zen will be something to recommend.

look at Cryorig's coolers
stuff like the H7 and R1, since they both have zero issues with RAM clearance whatsoever

I got the H110i GT and love it. If your case says it supports radiators then you will have clearance.

I've got an H7 personally, and it has no issues with super tall vengeance modules 

neither does the R1 universal (not ultimate)
