Hi, 

I have an Inspiron B120 that has served me well over the years & am looking to upgrade the processor from a Celeron M 360 1.4 GHz to a Celeron M 450 2GHz.  The User manual says:

Processor
Processor type Intel ® Pentium ® M or Intel Celeron ® M
L2 cache 2 MB (Pentium)
1 MB (Celeron)
External bus frequency (front side
bus) 400 MHz or 533 MHz

�

The 360 & 450 both support socket PPGA478 , the processing die size on the 360 is 87 mm2 & the die size for the 450 is 90 mm2.  Should I be concerned about that?

Voltages look pretty close.  The Max TDP on the 450 is 27W (360 is 21W) - I suppose that means the fan will just have to work a little harder to cool the 450.

The 360 FSB = 400MHz whereas the 450 FSB = 533 but it looks like according to the manual specs both are supported.

�

Can I swap out the 360 in favor of the 450?

Here are the specs for both:

Intel® Celeron® M Processor 360

Intel® Celeron® M Processor 450

Thank you
