2010 MBP processor

[vmachiel]

So I was wondering, what kind of processor is in my mbp. The new ones are called sandy bridge, but what were it's predecessors? Westmere or Nahalem?

 

[KwanMan]

depends which MBP you had

According to your sig, you have 2010 base 15" MBP. The CPU uses Nehalem micro-architecture but since it is a die shrink of original Nehalems, it has codename of Westmere. More specifically, it belongs to Arrandale family that represents mainstream mobile CPUs.

Every thing you always wanted to know about Intel Core processors but were afraid to ask.

Thanks for all the info

It is a Core i5 520M Arrendale CPU.
The most significant differences to the Dual Core Sandy Bridge in the new 13" MBP is that the Memory Controller is off DIE and even slower than with C2D and the GPU is much slower with less features. It is like a 2-2.4 Ghz Sandy Bridge Dual Core depending on the workload and how quick memory access it needs.
