You haven't specified what your needs are so it is impossbile to say what would meet your needs. With that said, L1, L2, and L3 refers to the memory cache that a CPU has. Each level of cache speaks to the distance the cache is located from the CPU with L1 being closest. Generally, L3 is less desirable than L2, etc.
Intel's processors each has a different amount of memory cache depending on class (all i3 and i5 haswells have 3.0MB while i7 ranges from 4MB to 8MB).

They are like small caches the CPU uses to quickly store and open tasks. The CPU cache is a lot faster than accessing RAM, so it is better to use this for specific tasks. Each level is often larger and slower than the previous. L1 being the fastest but smallest. L3 Being the slowest but largest. Some CPU's don't have an L3 cache. It is also common to see L2 or higher shared by all cores.

Correct me if I'm wrong, but I don't think you should worry too much about the cache as it is very likely to suit the intended application of the CPU.
If you want an intense CAD, rendering, video editing CPU, the cache is going to be capable of the tasks required, just as the cores and everything else involved are too.

thanks guys for replies
now I know that level 1 is faster then level 2. and level 2 is faster then level 3
but in practical, what is the different between these levels ?
I mean If you want to do some process that will consume from the CPU usage (like video editing)
how these levels will works ?
