Apple MacBook White 1.83GHz Intel Core 2 Duo/512MB/60GB/Combo Laptop With its 64-bit processor architecture, the Intel Core 2 Duo can manipulate data and execute instructions in chunks that are twice as large (64 bits versus 32 bits), delivering advanced computational power to MacBook. That adds up to a 6x performance boost over the iBook and 12-inch PowerBook before it(1) — speed and agility you’ll notice when working with photos in iPhoto, creating Keynote presentations, or editing podcasts in GarageBand.

The Intel Core 2 Duo — based on Intel’s advanced Core microarchitecture — offers a second-generation chip born of Intel’s new 65-nanometer process. That process lets Intel create incredibly small transistors — small enough, in fact, to fit a hundred inside a single human cell. With two powerful processors designed to share resources and circuitry so unimaginably small, the Intel Core 2 Duo achieves far higher levels of performance while actually consuming less power.

4MB of shared L2 cache augments the advanced Core 2 Duo processor on the 2.0GHz madels.(3) That’s double the amount previously available, and it really lets MacBook fire on all cylinders. With such substantial L2 cache, data and instructions can be kept close to those two processor cores, greatly increasing performance and allowing the entire system to work more efficiently. And, because the processor cores share the L2 cache, either can use the entire amount if the other happens to be idle.

The Intel Core 2 Duo’s enhanced, 128-bit SSE3 vector engine handles 128-bit computations in a single clock cycle, accelerating data manipulation by simultaneously applying a single instruction to multiple data. That means you can get more done in less time. So, the next time you use iMovie HD or Final Cut Express to render effects, you can thank the SSE3 vector engine for the snappier performance.

Helpful consumer’s review
I have the 1.83Ghz model upgraded to 1Gb RAM and 120GB Hard Drive, and from my old 1.3Ghz Windows laptop the improvement is amazing. The Macbook is very slim and fast and the OSX interface is in my opinion far easier to use than its Windows rival. The only quarrel I have with this laptop is the weight- it’s heavier than most laptops, but for the specs and the amount of hardware crammed into such a small space it seems no wonder. A great laptop for any student, and especially good when connected through a mini-dvi-VGA/DVI adapter to an external monitor. A quality laptop.
