MacBook Air (January 2008 edition) is a version of Intel’s Core 2 Duo shrink that adopted the use of 45-nm process using Penryn and many people have the wrong idea. In fact, 65 nm using a version of the Merom.

Apple, which uses technology, and more, if you do not publish, but some information from the public, it can determine.

The 1: Apple’s own version of 45 nm and is using it as I did not say a word

Mac Pro is the core of eight to 45 nm version using the Mac Pro site, and so it is written, the MacBook Air referral process is not written in the rules. Apple’s own version of 45 nm and is also said not a word.

The 2: shrink version compared to the same die size of the object

Macworld 2008 chip size

LE80537 written and normal size compared to the Core Duo 2, but this is Core 2 Duo T7400. That is the version of 65 nm Merom T7400.
And the same die size.Rules in the process, if it is smaller die size, die size change.

Intel 45nm and 65nm chip

45 nm version of the left and right are 65 nm version of the Quad-core products.

The 3: SSE3

Immediately after the public announcement, the MacBook Air SSE4 Developer Note has been written response. It also adopted Penryn reason was mistaken, but later modified SSE3.
Penryn is incidentally from the corresponding SSE4.

So let’s use what it is

4MB L2 cache, a 800 MHz FSB specification has been published and can say at this point is the ultra-low-voltage version is not. Version or normal voltage and low-voltage version can be expected.

This article is expected to be low-voltage version.

This article is in some greater detail.

The CPU is used MacBook Air, Penryn used ahead of the technology package, Penryn (Santa Rosa Refresh) or Montevina version of the main board is almost the same stuff used, such as body weight is almost unchanged . Instead, the battery life or performance either, or both things will improve in the coming six months or so may be.

And decrease development time, Intel and Apple’s recent honeymoon after considering the competitors ahead of Intel’s latest processor is the first to appear and will be Apple’s MacBook series that have the potential to become.
