PhoneNews claims they can "confirm" that Apple will speed-bump the MacBook Air with a Penryn-class Intel Core 2 Duo processor, increasing the clock speed to 2 GHz and up. The story also notes that, since the processor requires more power, the Air will ship with a higher-capacity battery and 60-watt power adapter.

Engadget goes further, noting that clock speeds could (theoretically) reach 3.06GHz. Also, they speculate that the Air could feature improved integrated graphics if it adopts the Intel Centrino 2 chipset.

Alternatively, Engadget notes that Intel plans to release several flavors of low-voltage Penryn chips in September, which might indeed be slated for the MacBook Air. Using these chips, however, would decrease the power requirements noted by PhoneNews, not increase them.

PhoneNews says national retailers have been alerted "to be prepared for the upgrade." This may be part of several laptop announcements rumored to be happening in September.

OK, they didn't really try to fry an egg. But for those of us using those first searing-heat MBP's, you'll be happy to know the Penryn MacBook Pro's are a little cooler (temperature-wise anyway). On average, about 10° F cooler, and the fans run slower and quieter. Sorry if this kills any MacGuyver-esque plans of using Penryn laptops as emergency griddles.

For a much more detailed analysis of the Penryn advantages, check out the Engadget post, complete with Xbench tests and a flavorful grid with all the analysis.

We finally got the new MacBooks and MacBook Pros we've all been waiting for and now it time to dig into the fine print a little bit. As we noted earlier the new machines are shipping without the $19 Apple remote, but there are also some other subtle changes worth noting:

• The processors are confirmed to be Intel's Penryn technology.
• Only the MacBook Pro is getting the multi-touch trackpad functionality of the MacBook Air. Apparently Apple is doing this deliberately to differentiate the higher-end portables from the MacBook line.
• Only the Pros are getting LED backlights, and that's standard only on the 15". LED backlighting is a $100 BTO option on the 17" and simply not available on the MacBook. This despite Uncle Steve's assurance that the entire Mac line would transition to LED backlighting "when technically and economically feasible." I suppose that Apple would say that it's not yet economically feasible in the MacBook line.
• The Pros feature a slightly new keyboard layout missing the virtual number pad.
• The Pros also have 3 USB ports now, instead of 2. Update: Oops, lots of people have pointed out that only the 17 incher has the 3rd USB port, and it has had that forever. Nothing to see here, folks. Move along.
• Perhaps most disturbing is that the official battery life estimates have dropped noticeably. MacNN notes that "Apple's revised projections falls to a maximum of 4.5 hours versus six [on the MacBook]... from six hours to five [on the 15" MBP and]... from 5.75 hours of use to 4.5" [on the 17" MBP].

Now none of these things is that big of a deal (hence the fine print), but there is some cause for concern, especially with the reduced battery life estimates. We may hope that perhaps Apple is being more realistic in their projections and that accounts for the reductions. It's particularly confusing given that one of the supposed advantages of the Penryn processor is energy efficiency. We won't know for sure until third-party benchmarks are available.

Thanks to everyone who sent in tips!

Since the Mac Pros announced earlier today are using the "Harpertown" desktop version of the chip, it should be no surprise that Intel's Penryn family of processors are shipping and in use, as announced at CES yesterday. The full suite of chips includes 16 devices, including four for server use, seven desktop parts and five for mobile devices or laptops.

With premium laptop vendors Sony, Lenovo & Toshiba announcing products built around the new Core 2 Duo parts, it would be downright shocking if next week's Stevenote did not feature at least one Apple portable sporting the new and improved 45nm processors. With the desktop and server bumps out of the way a week ahead of time (and who can remember the last time that happened?) the way is clear for plenty of excitement a week from now.

[Update 1:15 pm -- And this is why we don't often post product rumors... indications are that this is coming from someone posing as our "reputable source," and other sites have received and debunked the rumor. We tried to reach the source for verification but were not able to do so. Our apologies if this turns out to be complete bunk. -Ed.]

We don't often post product rumors hereabouts, although we're certainly not above reporting on them and linking to them; it's just not the regular beat. That said, when an email comes in from a reputable source (thanks, Mr. X) with supposed details on Tuesday's product announcement... well, we gotta let you all know. Pile on the disclaimers (this is a rumor!) and here we go. Our source says that there are plenty of new products coming on Tuesday:

Two new iMacs, with 20 and 24 inch screens, and entirely covered in brushed metal (!) plus the previously hinted new keyboard design and a slightly slimmer enclosure. Even more surprising, our source says the iMacs are shipping with a 2.4GHz Intel Penryn chip. Intel's first 45-nm CPU was originally slated to ship at the end of the year, and it's not clear that Apple could get enough parts to actually build these puppies before October, so take this with a grain of salt. The machines might ship with the dual-core Conroe part instead.

Three new Apple Displays at 20, 24, and 32 inches. These are supposed to have an iSight camera built in.

The Mac Pro will get a speed bump as the Xeon/Woodcrest chips are swapped out for Penryn chips, running at a brisk 2.4, 3.0, and 3.33GHZ.

Lastly, the long-expected end of life for the Mac Mini may finally come around as the machine is expected to be dropped from the product matrix. *sniffle*

Again, this is all unconfirmed. We'll know for sure on Tuesday!
