Radeon 5770 or 5870?

I just replaced the graphics card in my mid-2012 Mac Pro, but now I wonder whether I had the 5770 or 5870 in my machine? There are part numbers on the card but no model number. I'd like to sell it but need to know what it is. I'm guessing the 5770 but how do I tell?


Thanks!

True, except I replaced the card before checking that and don't want to go to the trouble of reinstalling it, plus since it isn't compatible with Mojave and I upgraded to that, not sure what the machine would do.

I'm going to assume it is a 5770 since I would not likely have paid for for more graphics power since I wasn't using the machine for graphics intensive things. Thanks for your response though.

No, the port configuration is the same for both cards.


Mac Pro (Mid 2010) - Technical Specifications

"• ATI Radeon HD 5770 with 1GB of GDDR5 memory, PCI Express 2.0, two Mini DisplayPort outputs, and one dual-link DVI port

• ATI Radeon HD 5870 with 1GB of GDDR5 memory, PCI Express 2.0, two Mini DisplayPort outputs, and one dual-link DVI port

• Option to install two ATI Radeon HD 5770 cards"


Two 5770's are allowed because each uses only one auxiliary power cable. There are only two auxiliary power connectors on the motherboard, so only one 5870 is allowed since it needs both.
