MacBook Air's processor riddle solved
Apple's new MacBook Air subnotebook raised eyebrows by using a mysterious new, ultra-compact Core 2 Duo processor. New research, however, reveals it to be a blend of old and new technology designed to make few sacrifices.
An in-depth study of the design by AnandTech founder Anand Lal Shimpi explains that the processor is actually based on Intel's 65 nanometer (65nm) Merom architecture with an 800MHz bus, first released in May of last year. All of Apple's current iMac, MacBook, and MacBook Pro models use some form of the processor at a higher clock speed. But rather than struggle to fit the hot, standard-sized processor package into the tight confines of the Air's chassis -- a feat deemed impossible by Jobs during the computer's introduction -- Apple appears to have called on Intel to accelerate the release of an extra-small chip package not scheduled to arrive until the launch of the Montevina notebook platform in mid-2008. "The MacBook Air uses the Intel Core 2 Duo Processor and Intel 965GMS chipset with integrated [graphics] using a new miniaturized package technology. This new CPU and chipset allows for approximately 60% reduction in total footprint," Intel explains in a response to the technology site. The mixture of current and next-generation parts creates an unusual blend of performance characteristics. The new Core 2 Duo slots just above the Low Voltage (LV series) variants in terms of clock speed and power use -- starting at 1.6GHz with 20 watts of thermal design power versus 1.4GHz and 17 watts -- but is considerably more efficient than the regular mobile processor, which consumes 35 watts of peak power at a minimum 1.8GHz. Apple may have been making "tradeoffs" to get the finished MacBook Air on the market in time, Lal Shimpi speculates. As for the reason behind choosing the new variant instead of stock low or ultra-low voltage Core 2 models, the report suggests only that Apple's main concern was to avoid the low speeds of these chips while compromising as little as possible on energy efficiency or heat. "Performance appears to be all but solved [for subnotebooks]," Lal Shimpi says. "The fact that Apple can cram a nearly-2GHz Core 2 Duo into the MacBook Air either means that Moore's law has caught up with our desires or Apple is going to make it so you can no longer have children." |

Hold up there Apple Insider. Anand is just speculating. There is some contradictory evidence on Apple's own developer page for the MacBook Air that suggests it may be a different chip.
"Intel Advanced Digital Media Boost accelerates data manipulation by applying a single instruction to multiple data at the same time, known as SIMD processing. SIMD technology accelerates vector math operations and floating-point calculations. Advanced Digital Media Boost supports Intel Streaming SIMD Extensions (SSE) versions 1, 2, 3, and 4 and allows the processor to execute most 128-bit instructions every clock cycle.:As far I know, Merom doesn't have and can't have the SSE4 instruction code.

Good point. Someone has made a mistake somewhere.

Can someone translate this into English for the lay user on the issues of whether it matters and if so, how (unless is it the usual inside-baseball tech b-s, which is what this AI news story sounds like)?
Thanks. (Add: One more thing. What exactly was the 'riddle' here -- see headline -- and who was flummoxed by this riddle?) |

Both chips look IDENTICAL to me, the only difference being trivial (namely, the card where they are mounted). Is this pure and sheer marketing buzz? Shocking! I WAS EXPECTING 45 NM IN ANY CASE!!!

Pbbbbbbbht
The Macbook Air reminds me of an 80's band name.... Fad Gadget. Put this one up there with the cube. Looks cool, smells cool, no buyers. Honestly, I got excited when I saw it... but let out a huge guffaw when Steve quickly announced the price before moving on. I'd buy one for sub $1000, but ffs, $1800 for slim ![]() You would think that excluding all that useful stuff like cd player, ethernet, card reader, audio out, firewire, decent processor, decent video card, swappable battery, ram upgrades... this thing should be $800. Glorified iPod. No wonder their stock took a dive. I've not talked to or heard a single person say "OMG... I'm getting one". Fad Gadget gang... nothing more then a fad gadget. ![]() ![]() ![]() |

It's still a very fair clock speed given it's size, it's going to produce less heat also.

I'm bored with the MBA, yes they should of put FW in it, its kinda of a Mac signature.
Roll on 10.5.2, I'm more excited about ... BTW 3 kids and next one due in 4-5 weeks. |

Why didn't they just throw in a ULV chip in there? The U7600 isn't slow at all, I've got one and I can do all the things that you'd be doing with the MBA. No one is going to be running games or editing video with this computer so why not get better battery life with a peppy ULV???

Comparing MacBook Air to the MacBook is not a fair comparison. Its like comparing the MacBook to one of Dells 2inch thick desktop replacement laptops. That is not its competition. You need to compare its performance to other ultralight notebooks. |

The notebooks based on ULV chips can get 10+ hours in some cases, but that trades off speed, and is more expensive. Often you need to get the optional bigger battery to do that.

I'm dying to hear how hot this thing runs, no comments on that from the guys who were at the show?
Wow, you don't really have any clue about the market for this kind of box. Take a look at other ultraportables. Comparable units are all at least as expensive. Is it really so hard to understand that making something smaller is more expensive? And the cube comparison is way tired...that was a huge mistake because nobody needs to make a desktop as small as possible. In a laptop, size and weight are huge selling points since you CARRY IT AROUND. |

The one thing that has been bothering me ever since I got the iPhone is Steve's vision of free wifi on every corner. It just isn't happening. With the Air having no cell card slot and no ethernet it is really dependent on abundant wifi. And by the way, the wifi networks and cell towers were so overloaded in SF during the show that no one was able to get on the web, not even at the Apple booth. And of course every notebook user understands that if it is going to be used for travel, you're going to need the external usb ethernet adapter, the bluetooth mouse the power brick and maybe even a usb hub because you only get one usb port on the Air. Try to fit all that in an envelope. m |

What's funny about the Cube and it's use as a comparison is that the Cube still lives in a slightly altered form. It's called the Mac Mini. The difference is that the Mac Mini doesn't seem quite as well made and costs less, but is even smaller.

Engadget blogged a Fujitsu Lifebook today. There sensationalist headline stated that it is lighter than the MacBook Air. The Lifebook has an 8.9" display, a 1.2GHz ULV Core Solo and mini-keyboard.
It escapes me how the the redeeming factors of the MBA are being so easily overlooked and how it can so easily be negatively compared to any ultra-portable. Did Jobs once call an ultra-portable? |

And none of the hotels I've stayed on business in the last few months have had wifi outside the common areas. The rooms still had a stupid ethernet port (across the room for the couch). Instead of the Ethernet adapter, though, I would recommend carrying an Airport Express around. If the hotel doesn't supply you wireless, supply it yourself. This has the advantage, too, that you can then have your iPod Touch, laptop, and whatever else using the network simultaneously. |

I think the bigger story (which everyone ignores) is Apple's ability to squeeze everything into a little board, which is smaller than any PC-on-a-board out there.
Imagine the next revision of iMac....it may well look like a regular display. LCD's are getting thinner and thinner too. Or the next eMac (education mac): 20 inch LCD w/ iSight. single USB for keyboard (then mouse). no 1394. Wifi (no Bluetooth). no optical drive. That will simplify the school labs so much, with a single power cord to plug-in (and keyboard and mouse), and that's it. Finally we go back to the simplicity of Mac 128K. |
