Compatible replacement for n11p-ge1-w-a2

[G.Beard]

Can anyone tell me what GPU IC(s) can be used to replace an n11p-ge1-w-a2?
Is there any resource online that lists compatible replacement chips?

Thank you.

These almost never die, C9560. But if there is garbage on the screen directly on power on, replace GPU + VRAM. Just use regular N11P-GE1-A2, the W is an Apple custom BS addition.
