Updates the graphics firmware on ATI Radeon HD 4670 and 4850 graphics cards to address issues that may cause image corruption or display flickering.

Today's new hardware announcement refreshed the Mac mini and iMac lines, and at long last, the Mac Pro was also given some love. In the 14 months since the last Mac Pro refresh there have been some significant hardware changes within the microprocessor world and within Apple's own line. The result meant that the Mac Pro, while still a beast, wasn't as cutting-edge as it has been in the past. Let's look at the update and see if that story has changed.


Processor and Chipset

The big news with this Mac Pro update is the Quad-Core Intel Xeon "Nehalem" processor. Intel's "Nehalem" is the latest breakthrough in Intel's 45nm space. The Mac Pro may actually be the first commercially available computer that uses the Nehalem-based Intel Xeon. The base configuration is a Quad-Core 2.66 Ghz Intel Xeon, but you can configure a Mac Pro with two Quad-Core 2.93 Ghz Xeons, effectively meaning 8 cores. As far as I know, the 16-core option for the latest Xeon won't be available until later this year. To put it another way, this is bleeding edge.

Looking at Apple's benchmarks (obviously, the independent tests that are sure to come will probably give a more accurate overall picture), the 8-Core 2.93 Nehalem-based Xeon processor offers some significant speed increases over last generation's 8-Core Xeon 3.2 Ghz.

Aside from pure processor speed, the new chipsets include an integrated memory controller, Intel's QuickPath, Turbo Boost and Hyper-Threading technologies. The Hyper-Threading implementation is especially interesting because it means you can run two threads on each core, effectively meaning your Mac can recognize 16 virtual cores on an 8-core system. This is a virtualization nut's dream.

On the memory front, a single Quad-Core Mac Pro can take up to 8 GB of RAM. If you do the 8-core option, that capacity expands to 32 GB.

Graphics and Displays

Last October, Apple committed itself to using DisplayPort technology for its products and displays. The unfortunate side-effect of that decision meant that users wanting a Mac Pro to go with that sexy new 24" Cinema Display were out of luck, because those displays require a Mini DisplayPort, something the previous generation Mac Pros just didn't support. No more. The new Mac Pro features both Mini DisplayPort and a dual-link DVI port, so you can hook up both a 30" Cinema Display and that new 24" LED beauty.

Apple is touting the new Mac Pro as having "the fastest Mac graphics ever". Indeed, the stock NVIDIA GeForce GT 120 (note, NVIDIA changed the naming convention of its graphics chipsets recently, but the GT 120 is based on the 9500GT chipset) with 512 MB of GDDR3 RAM is a pretty decent start, especially for video professionals. You can customize the Mac Pro to include the ATI Radeon HD 4870 with 512MB of GDDR5 memory, which is one of the latest and greatest cards available from ATI.

You can put in up to four GT 120 cards in the Mac Pro, meaning you can drive as many as 8 displays off the Mac Pro. That's the video setup of my dreams.

Mac Pro users -- it's time to power up the graphics capability of your machine! ATI has announced the new Radeon HD 3870 Mac & PC Edition. Whether you're a serious gamer or a graphics designer, this new card features 256-bit 512MB GDDR4 frame buffer memory, 320 stream processors, twin dual-link DVI ports to run two 30" Apple Cinema HD displays, PCI Express 2.0 support, and more.

One of our readers pointed out that you can even use the HD 3870 in Windows running in Boot Camp on a Mac Pro. The Radeon HD 3870 runs in any Mac Pro and will be available in late June for a MSRP of $219.

Thanks to TJ & Seth for the tip!

Apple just released an update for iMacs sporting either a ATI Radeon HD 2600 Pro or a ATI Radeon HD 2400 XT graphics card. According to Apple, the update will "improve system stability" by installing a firmware upgrade on the graphics cards. This does affect the newly released iMacs.

After this update is installed, you should see ROM version: 113-B2250L-259. You can download the update by opening Software Update (Apple menu > Software Update) on the affected system, or by downloading the installer package directly from Apple.

Apple also notes: To complete the firmware update process, please follow the instructions in the updater application (/Applications/Utilities/iMac ATI Radeon HD Graphics Firmware Update.app). The updater will launch automatically when the Installer closes.

FiringSquad, a site covering all things gaming, interviewed Derek Perez, the Director of Public Relations for NVIDIA (ATI's largest competitor), about yesterday's news of the AMD and ATI merger. Mr. Perez looks at the merger as a boost to their own business, excited that NVIDIA will be the only GPU company that supports both AMD and Intel. If this is true, however, this merger could wind up being a bad thing for Mac users as Apple's machines are 100% Intel Inside (yes, I know that slogan is dead now). FiringSquad didn't get much out of Intel, their only comment was basically "we'll get back to you after we're finished reading all this legal mumbo jumbo".

It's still way too early to tell, but I hope this merger doesn't mean that Apple's customers will lose one custom build option in the online store.

AMD, the #2 CPU maker in the world, has announced a purchase of ATI, a leading graphics card manufacturer, for $5.4 billion. IMG has more details on the buyout and the business end of things, but we're more interested in finding out what exactly this means for the Mac market. ATI currently supplies the graphics hardware in a good portion of Apple's machines, including the MacBook Pro I'm typing this on and my wife's iMac, so here's hoping ATI makes enough money from working with Apple to keep AMD - an arch rival to Intel - happy. Stay tuned for more details as they develop.

Oh those enterprising hackers, whatever are we going to do with them? First they're blazing their own trail by getting Windows XP on a Mac, and now they're overclocking their GPUs. Hardmac.com posted about one forum member's discovery (in French) that, when compared to similar PC notebook hardware specs, his MacBook Pro's GPU seemed to be a bit underclocked - by over 100 MHz. However, these specs are on paper, and I haven't seen reports as to whether this is a practice exhibited by other manufacturers.

So what's a hacker to do? Why, use ATI's tools to get some overclocking action on! ATI offers a set of video card tools that unfortunately are Windows only, but if you come to the same results and just gotta have some more MHz, using Boot Camp to run these tools under Windows XP ought to do the trick for you. Just don't blame us if your MacBook Pro suddenly morphs into liquid metal form.
