Yes, and while this is good news I noticed that it scores somewhere near a GTX770 in OpenGL. Compute performance will be better but...still have to mod a kext and run with csrutil trick.
460 works OOTB but is a slug.
Certainly seems a 460 variant is coming soon.

Nvidia card with similar 280X is a GTX680.
290X is a GTX780.
AMD has allowed themselves to become jokes of computer world, which explains why Apple teamed up with them.

You need a GTX 980ti. On OS X and OpenGL the 290X is as fast as the 980ti. |

If the new MacBook Pro has a discrete AMD RX 460 option, is it possible that RX 460 cards can be used OOTB in classic Mac Pros? Or will a little tweaking be required?

Looking at the specs for the RX460 vs my present HD6870, it hardly seems worth the spend performance-wise, although the former draws 76 W less power and may be quieter with one fan. Have the RX480 PC version problems been sorted for Sierra yet?

So I've got a weird issue with a recent RX 480 install. Went through the kext edit process, everything went fine. However, after the Apple boot chime, black screen, and goes nowhere. If I boot off the original 2600XT card, boots up fine, and I can just switch over the video cable to the new RX 480 inside Sierra, and it works with no issues. Only the initial boot process is a problem.
Is this somehow related to Filevault? Anyone run into a similar problem?

There's no way to enter a FileVault password without an EFI GPU, so you'll be stuck there.

I swear, every MacOS issue comes back to FileVault. I couldn't even install it with FileVault on this time around. Thanks for the response! Edit: Got it working. Just need to provide adequate enough time, and make sure your account is selected on boot. THe password field is highlighted, typing carefully and boots up! Does appear you still need to have an EFI enabled card in the machine, even though it's not the active one. |
