What does 8 mb cache vs 6 really mean?

[bobbykasthuri]

That is the main other difference I think between 15 " 2.4 GHz and 2.5 Ghz versions...Just curious when that makes a difference? I want a 15" for 'serious' data processing. I have about ~ 1tb of brain data that I want to analyze without being tied to a desktop and then ultimately render that data using 3d visualization software like 3d studio max (or Maya, etc.). Boss is picking up the tab and want to know if the extra 2 Mb cache will mean for me...

best and thanks in advance for helping a computer noob out

Just means you have 2MB more L3 Cache.

It's just where the CPU caches (stores frequently accessed information) ... You have 2MB more of data.

It's good but not mind blowing.

it will give you a small performance boost. L3 cache is a place where data can be stored closer to the CPU, kind of like how data stored in RAM can be accessed faster than HDD/SDD storage. L3 cache is one step closer to the CPU, providing faster access to the data.

That being said, for consumer purposes you'll never notice the difference.
