Slow Radeons 7xxx+ on MacPro3,1

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…..

AppleIntelCPUPowerManagement.kext

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.

 

Fuck you AMD!

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!

AMD Radeons R9 29..whatever

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.

OSX vs WIN on AMD/ATI

Same post as previous, but for amd videocard, 7950, osx 10.9 vs win8+catalyst 13.8b2

OSX 10.9

Win8 OGL

Win9 DX11

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.

Sapphire launched 7950 mac card

According to fudzilla, sapphire has launched 7950 radeon mac card. Therefore a hunt for its bios begins!

10.8.3 beta has ati 7000 drivers

10.8.3 update has ati7000 drivers:

ATI7000Controller.kext
AMDRadeonX4000GLDriver.bundle

10.8.2 update for new macs

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.

Mountain lion GM and Lion new beta

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.

Interesting things:
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)

11G15 10.7.5 beta update

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.
