The measures are based on average performance in mix typical apps in macOS and Windows: use information of, and the author own experience. For example, 50% means that the card is two times slower than ATI Radeon HD 7970 (100%/2=50%). The Relative Performance Index/Info - RPI - shows the difference between an average card performance and the performance of ATI Radeon HD 7970 = 100%. Nvidia cards that need web drivers don't have any pre-boot configuration support, Recovery support or createinstallmedia USB installer support.ĪMD cards that have native macOS drivers don't have pre-boot configuration support but have Recovery and createinstallmedia USB installer support and work after the drivers are loaded by Recovery or USB installer.

GPU OK backplane diagnostic with Apple OEM GPUs,Īny card that has native macOS drivers has Recovery support, no one has Internet Recovery - only Mac Pro late-2013 has Internet Recovery (MP6,1 has GOP pre-boot configuration support).

FileVault support (for macOS versions before Mojave),.

Startup Manager, the new name for the BootPicker/BootSelector,.

Mac Pro 1,1 to 5,1 supports UGA and a GPU that has UGA pre-boot configuration support has: No GPU besides original Apple Mac Pro GPUs from 2008 to 2012 (HD 2600XT, 8800GT, Quadro FX 5600, GT120, HD 4870/5770/5870) or 3rd party Mac EFI cards like Sapphire HD 7950 Mac Edition, eVGA GTX 680 Mac Edition, NVIDIA Quadro 4000/K5000 or self-flashed/MVC flashed cards have what are usually called boot screens - this is not the correct term and the correct denomination is pre-boot configuration support. And in many cases the only difference is special firmware, which can be easily flashed to the PC version.

original 'mac edition' cards are much expensive than PC version.

as usual GPU performance in macOS is lower than in Windows.

there are difficulties with powering GPUs (special cables, cable adapters, PSU mods).

several GPUs are compatible not with all cMP (for example - only with 1.1/2.1).

AMD/ATI GPUs are better supported by modern macOS versions.

most modern GPU are compatible with cMP, some of them - with nuances (for example - without Boot Screen).

What you may know to choose the right GPU:

GPUs which are not compatible with cMP at all.ġ.3.GPUs which can be flashed by special hardware to be compatible with cMP.GPUs which can be easily flashed to be compatible with cMP with some nuances.GPUs which can be easily flashed to be fully compatible with cMP.GPUs which are compatible with cMP out of the box with some nuances.'mac edition' GPUs (were officially made to work in cMP) which are fully compatible with cMP out of the box.They are very different in performance, power consumption, features. There are 50+ GPU types that are compatible with cMP (classic MacPro = Mac Pro 1.1-5.1/ 2006-2012).
