Of course they do. All manufacturers do this as a way to make a profit, but that is why you must educate yourself on what is better, and make an informed decision. Personally, if you are just a casual computer user, I would highly suggest looking for a dual core processor. They run seamlessly when Surfing the internet or playing games. However, if you are into extreme gaming or something of the sort that demands extremely high performance, I would recommend a quad-core processor or something of the sort. However, a quad core is not at all necessary for casual computer use.
The central processing unit (CPU) is a chip built into a computer that performs basic calculations that allow the computer to run. Processing power is a measurement of how powerful this chip is, i.e. how fast it can do the required calculations.
The first Pentium chips had a processing speed of 60-66 MHz
CPU - Central Processing Unit which performs logical calculations
It is a chip they call the central processor - it is generally connected to the other processing devices via the motherboard also uses a battery to keep it's memory the connection is via solder on the motherboard http:/encyclopedia.farlex.com/Computer+processing+chip
The CPU or Central Processing Unit.
Central Processing Unit is the main chip of computer. CPU fetches and executes instructions. CPU consists of an Arithmetic and Logic Unit (ALU), a control unit, registers and buses.
The first Pentium chips had a processing speed of 60-66 MHz
It is the main chip on a computer that is doing all the data processing and run the programs.
The A5 chip
Yes CPU is the most important chip in the computer because it is the brain of the computer. So, without brain nothing work properly.
microprocessor
That is the microprocessor, some call it the CPU (Central Processing Unit)
