Can anyone tell me about Intel processors?

There are a number of processors out in the market now,

I notice some are marked 45nm and some are 65nm. What is the meaning of 45nm and 65nm? What are they for?

Can someone please tell me?

Those are how big the microscopic circuit traces on the silicon chip are.

45nm uses smaller circuits than 65nm, i.e. 45nm is more miniaturized. Each circuit trace on the silicon trace is only 45 nanometers wide (that's 45 billionths of a meter).

The more miniaturized a circuit is, the less electrical power is needed to operate it, which means it runs faster and runs cooler (generates less waste heat).

Is that so? So they should just scrap the 65nm technology then.. What processors already use 45nm chips?

I guess at the end of the day, its business as usual my friend.

Hey! I didn't know about that til now. Do you guys know any good company selling with that 45 size? I'm interested with what you guys said.

45nm chips are cheaper... Its not like everyone has money you know.

Mmmm 45nm. I still have the 65nm e4500 under my rig. Smaller can have less power comsumption but with the new trend of new hardware coming out ever 6 months, I'll stick with my 65nm for now.

Smaller the better. There is a new Video card in the market called HD4770 that has 40nm process, Gotta love those smaller ones.

820 is a part number go to Laptop, Notebook, Desktop, Server and Embedded Processor Technology - Intel for information.

what is a CPU Ghz, Ghz = 1 billion Hertz, ( 1,000,000,000 )
or cycles per second in simpler terms.The bigger the number the faster it can execute a set of instructions.
Slower speed CPU's will take long to execute the same set of instructions.
Also CPU speed is only one part that determines the speed of a computer.
Other factors like
FSB ( Front side Bus )
How much memory ( L2 and DDR )
Hard drive speed
