Re: yonah vs merom
Ok, I will try to explain :hehe:
The Yonah is a complete new architecture built from the ground up (in Israel 
) and is the latest CPU from Intel. The Yonah is processor which giver better power to watt ratio then the Pentium 4 and the Althon 64 and that for a laptop cpu
The Yonah is a two-in-one cpu which means its basically two processors in one package. The main difference between the Yonah which is for sale now and the Merom is 32+64 bits CPU.
32-bit* refers to the number of bits](http://webopedia.internet.com/TERM/3/bit.html) (the smallest unit of information on a machine) that can be processed or transmitted in parallel, or the number of bits used for single element in a data format. The term when used in conjunction with a microprocessor](http://webopedia.internet.com/TERM/3/microprocessor.html) indicates the width of the *registers](http://webopedia.internet.com/TERM/3/register.html"); a special high-speed storage](http://webopedia.internet.com/TERM/R/storage.html) area within the *CPU](http://webopedia.internet.com/TERM/R/CPU.html). A 32-bit microprocessor can process data and memory addresses](http://webopedia.internet.com/TERM/3/address.html) that are represented by 32 bits. 64-bit therefore refers to a processor with registers that store 64-bit numbers. A generalization would be to suggest that 64-bit architecture would double the amount of data a CPU can process per clock cycle](http://www.webopedia.com/DidYouKnow/Computer_Science/2004/clock_tick.html). Users would note a performance increase because a 64-bit CPU can handle more memory](http://www.webopedia.com/DidYouKnow/Computer_Science/2004/memory.html) and larger *files](http://www.webopedia.com/DidYouKnow/Computer_Science/2004/file.html). One of the most attractive features of 64-bit processors is the amount of memory the system can support. 64-bit architecture will allow systems to address up to 1 terabyte](http://www.webopedia.com/DidYouKnow/Computer_Science/2004/terabyte.html) (1000GB](http://www.webopedia.com/DidYouKnow/Computer_Science/2004/gigabyte.html)*) of memory. In today’s 32-bit desktop systems, you can have up to 4GB of RAM (provided your motherboard that can handle that much RAM) which is split between the applications and the *operating system](http://www.webopedia.com/DidYouKnow/Computer_Science/2004/operating_system.html)
I hope this clears it up
But yeah you could wait, I believe the merom will be shipped out within two months or so So if you can wait…wait.
If you cant, buy the Yonah Mac. The difference between the two wont be that much
