A closer look at Apple's Core 2 Duo MacBook Pro
Examined broadly, Apple Computer's new Core 2 Duo-based MacBook Pro notebooks are strikingly similar to their predecessors, though more careful inspection has turned up a number of notable tweaks and enhancements.
Introduced last week in 15-inch and 17-inch configurations, the new professional Apple notebooks utilize Intel Corp.'s new Core 2 Duo (Merom) dual-core processors with 4MB of Level2 cache compared to the Core Duo (Yonah) chips used in the previous version, which featured 2MB of Level2 cache. The processor The larger L2 cache means that the transistor count in the Core 2 Duo MacBook Pro has been expanded from 151 million to 291 million. This allows for an increase in cache-to-processor data transfers, maximizing main memory-to-processor bandwidth and reducing latency. Additionally, Merom sports a slightly deeper pipeline than Yonah (increased from 12 to 14 stages), which also helps to increase clock speeds. However, just like the Yonah-based MacBook Pros, the chips inside the new Merom models are soldered to the main logic board. Heat dissipation Compared to the Yonah MacBook Pro at 31 watts, the new Merom models sport a slightly higher Thermal Design Point (TDP) of 34 watts. However, the increase is not significant when viewed against the increase in performance. Thus, the new MacBook Pro can be seen as more power efficient than its predecessor. Aside from computational enhancements brought on by the Core 2 Duo, Apple has made several alterations to the design of its professional notebook line, both externally and under the hood. Hard disk noise dampener For starters, the new MacBook Pro ships with hard drives the come with a metal disk attached to their top cover to dampen hard drive noise. The disk is not removable, meaning replacement drives will need to be ordered directly from Apple until a third-party solution is developed and deployed. The MacBook Pro Core 2 Duo's hard drive noise dampener | Photo: iFixIt AirPort and Bluetooth changes Located just above the hard drive is a newly designed Apple AirPort Extreme wireless card, which utilizes a color-coded three-wire antenna solution. True to rumors, the card identifies itself as an Atheros AR5008 with an 802.11n chip-set supporting the draft 802.11n wireless protocol. The MacBook Pro's Bluetooth implementation continues to be handled by a separate component card, which in the new systems has been relocated from the bottom case near the hard drive to a position underneath the top case. Audio alterations Meanwhile, a significant design change has been made to the notebook's right audio speaker module, making it a single piece of hardware. In the previous version of the MacBook Pro, the speaker housing was mounted below the main logic board and the right speaker driver was mounted through the board into the housing with its wire running over the top of the board. With the new single piece design, the entire right speaker is installed first and the logic board placed on top of it. This means the entire logic board must be removed to access speaker. Additionally, the wires for the speaker are now routed below the logic board, under the heat sink and along the back of the system. The MacBook Pro Core 2 Duo's new AirPort Extreme Card | Photo: iFixIt New connectors for fans and thermal sensors While some operations have become slightly more challenging within the new MacBook Pro, Apple has taken measures to simplify others by utilizing the same JST wire bundle connectors used in the 13-inch MacBook. The connectors are easily plugged and unplugged like a power cord. Casing alterations Although new MacBook Pro can easily be mistaken for its predecessor, the inclusion of a FireWire 800 port on the logic board of the new model makes its bottom case incompatible with previous MacBook Pro models. Similarly, internal revisions prevent the keyboard from the new 15-inch model from being used for repairs to the previous model because the caps lock key will fail to function properly. The MacBook Pro Core 2 Duo's main logic board | Photo: iFixIt System software Both 15-inch MacBook Pro models, as well as the new 17-inch model, are shipping out of China pre-loaded with Mac OS X 10.4.8 build 8N1037, BootROM version 00A5.00, SMC firmware version 1.12f5 and infrared firmware version 110 software. They also include Trackpad v13 and Camera v184. User-installable parts (memory) The new MacBook Pro does not contain any internal user-installable parts with the exception of memory. Although the notebooks will accept up to a 2 GB SO-DIMM in each of its two memory slots, the system will only recognize 3 GB of total memory. For external shots of new MacBook Pro, please check out an earlier report published on Tuesday. |

hang on a minute, oh rite, thats how, woops
interesting about the 802.11n, nice to see apple planning ahead. i would say possible airport upgrade, but seeing as this 'standard' is still quite far away from release, ill just have to ponder...

3GB or 4GB RAM?
"Although the notebooks will accept up to a 2 GB SO-DIMM in each of its two memory slots, the system will only recognize 3 GB of total memory."
Does someone want to explain this to me? -- I can put 4GB of RAM into the MBP, but I only get 3GB out of it (because the computer will only recognise this much). |

These are nice and all, but I'd really like to see some with a shallower depth of field.

I like how the iSight indicator light has now vanished into the aluminum bezel. Go Mac!

I wonder if anyone would be interested enough to put unboxing pictures of a Dell up on the Internet.
If someone did, I wonder if anyone would actually look at them. |

I'd look, just to see how ugly the arrangement would be and laugh.
...Since, well, I'll never un-box a Dell. lol |

on each side
Quote:
That usually consists of three layers, a thin layer of aluminum or SS on each side, bonded to an equally thin layer of elastomer in the middle. This turns the vibration into a shear force. As the layers can only move so much, it is turned into a (very little) bit of heat instead, dampening the system. The material isn't expensive (in aluminum, SS is several times as much), and I use it all the time. You can get it with a layer of very tough adhesive on one side from McMaster-Carr, and others.

What I'd like to know is why you can't have twin hard drives inside the 17-inch version!

Yeah, but you'd think there's enough space INSIDE!

Despite undestanding the 3GB limit its still kind of odd. youd think that they wouldve addressed this. I mean these numbers are just too crazy!

Jeez, there's hardly anything to these machines nowadays.
I'm constantly amazed at how much power they can pack in to such a small space.

new keyboard caps lock?

What's changed with the new keyboard caps lock on the core 2 duo? Please tell me they didn't bring back the ADB keyboard! Last edited by ericm; 10-31-2006 at 10:05 PM.. |

PC's are the same, they advertise 4GB, but if you read the small print they usually mention that "some ram may not be accessible" or something like that.

I agree with others regarding the 3GB memory limit, maybe it is a firmware upgrade? It would be great if it were only a firmware issue that could be resolved.
Also, it would have been nice to have a user installatble hard drive like the MacBook has. Maybe next rev. will see that. It would be nice if Apple would maybe change the connector for Firewire and call it Firewire 2 so that it will support either 400 or 800 and use only one cable connector much like USB 1.0 and 2.0. Other than that, the laptop looks GREAT! It is hard to improve on a good design, but I am sure Apple will always figure out a way to make it better as they come out with updated models. It is only a matter of time when the 4 core models will be shipping....... We'll probably have to wait another year or two. Ah, the life and times of an Apple user. We are always going to be dreaming of the next model. When will it stop? HOPEFULLY NEVER. Go Apple!! |

They could use the Firewire 800 connector couldn't they? It still supports Firewire 400 does it not?

They could just use a Firewire 400 to Firewire cable couldn't they? It would sure free up some connector space on the laptop. I think that is a small price to pay for convienence.

Oops. FIrewire 400 to Firewire 800, I mean.
