G645 or e5200 cpu are all from Inter Milan.

G645 is a process of about 32 nanometers, with Sandybrige architecture.

E5200 is a series of meat buckles with ~45nm technology.

Although it's all porn.

But the architecture of G645 is more advanced than E5200 ~

Even the performance of G620 at low frequency is slightly better than that of e8400.

So G645 must be better than E5200 ~
