what is the Difference between laptop CPU T8100,T8300,T9300

Hello
What is the difference between the 3% CPU T8100, T8300, T9300. I just want to have comparison to use only audio .... no games ....

for info
Intel Core 2 Duo Mobile T9300 - 2.50 GHz - 800 MHz FSB - 6MB L2 Cache
Intel Core 2 Duo Mobile T8300 - 2.40 GHz - 800 MHz FSB - 3MB L2 Cache
Intel Core 2 Duo Mobile T8100 - 2.10 GHz - 800 MHz FSB - 3MB L2 Cache

What is the difference between as cache memory 6Mb and 3Mb it plays on what?

I think you will most likely on the video & sound> audio.
I do not know if the cache much influence in cubase but power for cpu plugin is important,casts an eye on google

In theory, it is faster to get the calculations ...

I do a lot of research in google,I found that the difference between T8100 and T8300 is about 13%,T8300 and T9300 is 4%, but it is based on tests that have nothing to do with cubase ...
