my Laptop is Sony VAIO DUO 13.3
Model : SVD132A14W
I want my laptop to be faster.
If it were that simple to go from a 4th gen to a 9th gen processor....
As your processor is soldered to the motherboard (has a BGA socket), so you will never be able to upgrade it.
If it were not soldered, you must still ask Sony what processors are compatible with THEIR BIOS. Then, you could select from those processors. Alas, you cannot do this.
An upgrade processor must be socket, chipset, and BIOS compatible.
Just for comparison purposes, here are the four processors you asked about.
I will add that, except for rare cases (not yours, however), replacement processors must come from the same processor generation. That is, i5-4xxx or i7-4xxx. Al is correct; only Sony can tell you what processor upgrades might be possible (are supported by their BIOS).
Hope this helps,
