Can I upgrade nvidia graphics processor?

Thanks to iFixit I have upgraded my 15” Mid 2012 MacBook Pro in several ways: 16 GB RAM, 1 TB SSD and new battery a few weeks ago.

There is one more place I’m hoping I can upgrade: The NVIDIA GeForce GT 650M which has 1 GB of dedicated VRAM.

It’s on a PCIe bus, so it might be on a plugin card that could be replaced with a higher performance video processor.

Of course even if it was upgradeable, compatible parts may no longer be available.

Chips and boards are very different! The GPU soldered to your logic board and a direct feed to your CPU & PCH chips as you can see here, The Red outlined chip is the GPU, the Orange is the CPU and the Yellow is the PCH chip:

Here’s a listing of all of the systems within this series: MacBookPro9,1 All three had NVIDIA GeForce GT 650M GPU’s so there is no logic board upgrade possible,

A PCI board is a very different animal and you can’t alter your systems logic board to support it. What you can do is get an external PCI case to install a PCI GPU and connecting via Thunderbolt to your system. There was a company that made a external PCI box that would work using a feed through to an external display. You’ll need to look for a used one as the current crop of external GPU's are Thunderbolt 3 and won’t work with your system.

FYI - This series systems are still highly sought! People who want to have a more serviceable system prefer it. And of course it offers USB-A ports and don't not have the Butterfly keyboard the new systems have.
