According to a forum post on tonymacx86, Apple’s latest release of Mountain Lion, the 10.8 developer preview, is able to natively support AMD Radeon HD 6950 and 6970 without the need for any tweaks or hacks. As for the 6950 and 6970 specifically, the reports originate from the netkas.org forums where several posters report a 6950 running Netkas EFI working natively in 10.8. One poster even reported the 6950 continues to be recognized in Lion with unmodified drivers after “warm booting back to Lion from Mountain Lion.”

There are still issues, as tonymacx86 posters pointed out: “It looks like the 69xx situation seems a bit immature and experimental at this point. Even in the new OS.” Another forum poster claimed NVIDIA 5xx cards also seem to run natively with mkchis claiming full support for the GTX 570 graphics card with no hacks or mods. He said it is “running at full res even smoother than a patched Lion. It’s like native.”

When it comes to booting from Mountain Lion to Lion with unmodified drivers, one poster warned it does not seem to work if you are connecting a display to the 6950. The good news is a prominent hackintosher informed us that Chimera was updated to run on both Lion and Mountain Lion with a dev release coming within days:

We’ve fixed Chimera to work with both LIon and Mtn. Lion- there was a small change necessary to boot 10.8. We’ll be releasing that in a day or 2 for devs.

As a side note for Mountain Lion support, Robservatory shared its method of getting VMware Tools to work when running Mountain Lion in VMware Fusion. According to the post, Mountain Lion “will kernel panic” when trying to install VMware Tools. Here is the fix:

It looks like Apple could (again) select the graphics giant Nvidia as the primary GPU provider for the upcoming Mac Pro hardware refresh. According to a mostly speculative story by MIC Gadget based on unnamed industry sources, new Mac Pros will feature Intel’s upcoming Ivy Bridge chipset fabbed on the chip maker’s latest 22-nanometer Trigate transistor technology (no surprise there). According to Intel, 22nm Ivy Bridge silicon claims a 37 percent speed jump and lower power consumption compared to the chip giant’s 32 nanometer planar transistors. ‘Trigate’ Ivy Bridge chips can feature up to eight processing cores and are more power-savvy, so they should help scale frequency, too. On a more interesting note, MIC Gadget speculates Apple could switch back to Nvidia as the primary supplier of next-generation GPUs for the new Mac Pros.

Nvidia has their “Kepler” platform due out around the same time as Intel is making their changes, and our sources within the company indicate that they have chosen to have Nvidia lead the charge so to speak on the graphics front.

Eagle-eyed readers could mention that AMD recently released the Radeon HD 7970 graphics card powered by the Tahiti GPU (its nearest rival is Nvidia’s GeForce GTX 590), with observes deeming it Apple’s go-to graphics card for future Mac Pros. Indeed, traces of support for Tahiti-driven AMD GPUs are found in Mac OS X Lion 10.7.3, at least indicating people might be able to upgrade their future Mac Pro with this card. Oh, and it’s great for Hackintosh builders, too.

Also indicative is a March 2011 Snow Leopard 10.6.7 update that enabled support for a bunch of AMD/ATI Radeon HD 5xxx and 6xxx cards, not all of which were in Macs at the time. On the other hand, a speculative switch to Nvidia would not be out of character as California-based Apple is known for frequently switching between Nvidia chips and those manufactured by rival AMD…

As Apple transitions its line from NVIDIA graphics cards to AMD (and opens up the OS to much more variety), we’re noting some strong words coming out of each camp on who makes the fastest graphics card in the world.  On the 8th of this month, AMD announced it had released the fastest Graphics card on the market, the AMD Radeon HD 6990.

NVIDIA fired back this week and said they had the fastest Graphics card.  Now it is getting real.

Dave Erskine, Senior Public Relations Manager for Graphics Desktop at AMD just fired this off:

We combed through their announcement to understand how it was that such a claim could be made and why there was no substantiation based on industry-standard benchmarks, similar to what AMD did with industry benchmark 3DMark 11, the latest DirectX® 11 benchmark from FutureMark.

So now I issue a challenge to our competitor: prove it, don’t just say it. Show us the substantiation. Because as it stands today, leading reviewers agree with us here, here, here, and here that the AMD Radeon HD 6990 sits on the top as the world’s fastest graphics card.
