"AT88SC" - Just another EEPROM.
As is "MEC25LV512" too.

I'm quite sure either of those APV7067Ns is the vGPU phase controller. As it happens the vGPU choke is the "1R0" in this pic and one of the APV7067Ns is right behind it on the backside...

Too bad no datasheet can be found using the partnumber available.
Good thing pin designation of phase controllers is usually standard...
