The IT Stuff

A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations.
Level 1 cache actually resides in the processor core and runs at [...]

“Double Data Rate, Two” or simply, DDR2, is an extension of a system’s standard DDR memory. Like DDR, DDR2 transfers data on both edges of the system clock, which allows the bandwidth of the memory to equal twice that of Single Data Rate memory, or SDRAM. DDR2’s architecture is intended to increase efficiency and performance [...]

Intel introduces 32nm process technology with second generation high-k + metal gate transistors. This process technology builds upon the tremendously successful 45nm process technology that enabled the launch of the Intel® microarchitecture codename Nehalem and the Intel® Core™ i7 processor.

It Incorporates multiple processor execution cores in a single package in order to deliver full parallel execution of multiple software threads
It put  multiple execution cores into a single processor as well as continuing to increase clock frequency
By incorporating multiple cores, each core is able to run at a lower frequency, dividing among them the power [...]

The terms 32-bit and 64-bit refer to the way a computer’s processor (also called a CPU), handles information.
The 64-bit versions of Windows can utilize more memory than 32-bit versions of Windows.
By using 32 bits your processor can represent numbers from 0 to 4,294,967,295 while a 64-bit machine can represent numbers from 0 to 18,446,744,073,709,551,615.
64 bit  [...]
