Most laptops cannot be upgraded easily, except for a few very specific components (often just the RAM and mass storage options, and sometimes not even these). In particular, components like the CPU are usually soldered straight onto the motherboard. Laptop manufacturers do this partly because it is cheaper to mass-produce, but that is not the only reason: upgradeable sockets make the board bigger and heavier, and laptops cannot be too big and heavy, or people will complain.
Technically it is possible to remove and replace components that are soldered right onto a motherboard, but it is an extremely difficult process, and you risk ruining the motherboard if you get it wrong. You would also need to replace each component with one that is drop-in compatible with the old one, and I'm not sure that the chips you're referencing are compatible in that way. It would be easier to replace the whole motherboard, but this is more expensive, and it only works if somebody makes a motherboard in the right size and shape to fit into your laptop case.
In other words, I don't think you can upgrade your laptop in the way you've asked about. Others have suggested upgrading your RAM or replacing your HDD with an SDD, and these may be better options for making the machine faster.
