Detailed explanation-1: -Clock speeds This means that a dual-core processor can run 14% faster. So, if you have a single-threaded program, the dual-core processor is indeed more efficient. On the flip side, if your program can use all 4 processors, then the quad-core will then be about 70% quicker than the dual-core processor.
Detailed explanation-2: -With every tick of the clock, the CPU fetches and executes one instruction. The clock speed is measured in cycles per second, and one cycle per second is known as 1 hertz. This means that a CPU with a clock speed of 2 gigahertz (GHz) can carry out two thousand million (or two billion) cycles per second.
Detailed explanation-3: -The different types of processors are microprocessor, microcontroller, embedded processor, digital signal processor and the processors can be varied according to the devices.
Detailed explanation-4: -A quad-core processor is a chip with four independent units called cores that read and execute central processing unit (CPU) instructions, such as add, move data and branch. Inside the chip, each core operates in conjunction with other circuits, such as cache, memory management and input/output ports.
