It’s known for a while that GCN radeons are low performers on 2008 MacPro using OSX 10.9
And the reason for this is…..
Apple fucked up some CPU power management resulting in videocard not running properly. plz fix.
Just remove AppleIntelCPUPowerManagement.kext and AppleIntelCPUPowerManagementClient.kext if you like to workaround it, speedstepping still works, cpu isn’t hot/cosuming a lot, still drops the clocks.
Wanna use AMD and nvidia card in one system, AMD says no.
wanna use radeon 2600xt (uses legacy driver) and modern videocard in one system? AMD says no
AMD has the worst driver programmers I ever saw. To be able to have two different display drivers running in one system is just too hard for their small retarded minds. Every driver release gets worse. fuck you AMD!
This wednesday AMD gonna announce online their new videocards, some of them might be able to beat gtx Titan.
OSX 10.9′s amd driver seems to know something about these new cards already
Radeon HD Hawaii XT Prototype
Radeon HD Hawaii PRO Prototype
Radeon HD Hawaii Unknown Prototype
not much tho, but we might hope for osx support sooner than later.
Same post as previous, but for amd videocard, 7950, osx 10.9 vs win8+catalyst 13.8b2
OSX AMD drivers are 34% slower than windows ogl drivers and 51% slower than windows DX11 drivers
such result could be due to extreme tessellation mode and inability of osx drivers to handle it fast enough. Also 8xAA made a big hit.
According to fudzilla, sapphire has launched 7950 radeon mac card. Therefore a hunt for its bios begins!
Apple posted Mountain Lion update for new macs (new imac, macmini, 13″ rmbp), which was shipped with custom 10.8.1.
The update is 10.8.2 with very fresh video drivers.
Nvidia drivers – 304.10.20f04
AMD drivers has acceleration support for 7xxx series (in amdRadeonAccelerator.kext), but no framebuffer driver for these cards.
P.S. no good news for 6970.
Apple just released ML GM, aka what will be the rtm of ML.
Video drivers in lion was slightly updated.
More info will be posted later.
1) they have cleaned ML, there is not a single kext with 32-bit part anymore.
2) video driver support is same as in dp4: 6970 with a patch and cold boot bug( cmon apple/amd, you had it fixed in dp2 and have it now fixed in lion). Nvidia gtx670/gtx680 works, no GE/aty_init or efi(on a mac needed)
GPU drivers are exactly same version as in MBP2012′s update pkg.
At least you can use 10.7.5 beta update to get drivers installed the Apple’s way.
