It's no surprise to hear that Leopard smokes on the latest Intel box, right? That's all fine and dandy for new Mac owners but what about the rest of us (the majority) who are still pumping that legacy PowerPC architecture beneath Cupertino's OS? How does Apple's OS of tomorrow run on say, an 8 year old Power Mac G4 (AGP Graphics)? We decided to find out. Our test machine sports a paltry 512MB and 1GHz clock courtesy of an after-market CPU upgrade (was 400MHz) -- just a tad better than the 867MHz / 512MB minimum requirement. While the box held up surprisingly well, there's one major problem which you old-timers should be aware of.

Most of you didn't bite on the last Mac Pro rumor from Think Secret. New Power Mac case design, sure, but the idea of them sporting Intel's Core 2 Duo (aka, Conroe) procs just didn't fly what with Intel's more flexible 64-bit Xeon (Woodcrest) chip already loosed. No sweat, enter AppleInsider whose sources claim that Intel's dual-core Xeon series processors will power those new Mac Pro desktops (and Xserves, too) which would finally give Mr. Jobs access to that elusive 3.0GHz marker, the current top-o-the-line Xeon clock speed. See, Xeon chips feature the Land Grid Array (LGA) 771 socket which allows for the multiple processor configs we've come to expect from Apple's professional desktops. According to AI, we can expect a dual-processor Xeon Mac Pro at the top-end when launched. Of course, both rumor sites could be right -- a single, high-end Core 2 Duo offered in the entry level Mac Pro with a quad-core Xeon config topping things off. Either way, they agree it's all going down at Apple's WWDC, so we'll know soon enough.

The Apple rumor-mill is all but certain that new Power Mac G5 replacements will be unveiled during Steve Jobs' WWDC keynote on August 7th. Now, Think Secret has "confirmed" that unlike the other Mactel's released to date, Apple's new top-of-the-line desktops, likely dubbed the Mac Pro, will sport a "substantially different" enclosure from their ancestry. The new boxes are also said to sport Intel's Core 2 Duo (Conroe) chips in configurations similar to the most recent Power Mac G5s; a single, dual-core proc in the low-to-mid range systems with top-end systems going 2 x dual-core for some hot, quad-core action. No word on clock speeds, unfortunately. TS' sources also claim that the MacBook Pro will also see a redesign when the mobile version of those Core 2 Duo (Merom) chips are released around August. And, uh, no we don't have any pics of the new designs -- a statement sure to incite graphic designers everywhere into a development frenzy of purported spy-shots. Of course, if you've got the real deal, well, you know where to find us.

Now that Apple has rolled out the MacBook, speculation has turned to the sole remaining PowerPC-based computer in the company's lineup: the Power Mac G5. And, as of today, there seems to be at least one thing that can be confirmed about the new computer: it will be called the Mac Pro. At least that's the assumption that can be made based on a recent Apple trademark filing, in which the company claimed the Mac Pro name for, among other things, "computers, computer hardware, computer software, computer peripherals, notebook computers, laptop computers, tablet computers, computer servers, handheld computers and mobile computers." Which means, of course, that this really doesn't confirm anything, except that Apple likes products with the words "Mac" and "Pro" in them -- which we kind of already knew. And this also raises at least one new question: if the Power Mac becomes the Mac Pro, will the iMac become -- a la MacBook/ MacBook Pro -- just the Mac?

Update: Thanks to Jeff for pointing out that there is still one other PowerPC-based computer in Apple's lineup: the Xserve. We'll have to wait a bit to see whether they decide to rename that one.

Want an Intel-based Mac but don't want to pay Apple's prices? A company called Red PCs may have what you're looking for -- if you're willing to face the wrath of Apple's lawyers. Red PC is now offering something they're calling a "PowerPC G6 Macintosh" for $499. According to the specs, the box is basically a generic Pentium-based PC running a hacked version of the Intel version of Mac OS X. For your $499, the company is also throwing in copies of Photoshop CS2 and Microsoft Office 2004, making this quite the deal, given that Photoshop alone can go for over $400. But, then, we assume you're prepared to deal with Adobe and Microsoft's lawyers as well if you're ready to buy this. Unfortunately (or fortunately, as the case may be), the Red PCs web site seems to be down, though the machine is still listed on the Alibaba.com site as available for purchase with free global shipping and a one-year warranty.
