Hi all, forgive the long winded windup and question... 😬
My current setup is a 2015 15" MBP connected to a pair of apple thunderbolt displays. As I understand it, the MBP does not have a separate graphics card/processor, so the work of connecting to the external displays falls onto the CPU.
My physical setup is such that the MBP is not in an air conditioned space (although the external monitors are) - this is a small home recording studio. The MBP is outside the room to decrease the fan noise while recording.
On hot days, and even some medium days, which are frequent here in LA, the MBP is slow, sometimes to the point of not being usable. The internal fans are spinning like crazy. If I unplug one of the monitors, this seems to help. Occasionally I also get green flashes in OBS studio while streaming live video, which I understand is also a CPU limitation issue. In this case, unplugging one of the monitors seems to help too, but it's not night and day.
I normally have the MBP clamshelled so that it's processor doesn't have to think about graphics for its built in display. (although I imagine the cooling might be better if it were open...)
Now, all that being said, I have two questions:
1. Is my assumption right, that MBP doesn't' have a separate graphics processor, and the external monitors are working the CPU harder? Is there anything else I can do to alleviate this? (I'm already using a circular fan blowing across the MBP to help get the air moving...)
2. I'm looking at a new machine in the near future. 2020 iMac i9 most likely, but I'm thinking about what I want to do with the graphics card. Will one of the upgrade options on the graphics card help with this problem?
Thanks all
Geoff
