However, these features are generally not a direct result of 64-bit registers or address or data bus design. hyper-threading and fast data exchanges. faster system clock speeds and bus speeds.What's the difference between a 32-bit and 64-bit processor?Ħ4-bit processors may include and support the following advanced technologies: Processors also include signaling for a third control bus, but this bus is typically a unique collection of discrete, or individual, digital signals and does not operate like an address or data bus. The data bus is the pathway used to exchange data with the intended address. The address bus is the pathway of electrical signals used to determine the device or memory address that the processor is attempting to access. This typically corresponds to an address bus and data bus that are also 64 bits wide. This has become a de facto way of classifying or categorizing modern processors.Ī 64-bit processor uses internal registers - temporary storage locations within the processor - that are 64 bits wide. Thus, microprocessors are tied to memory where applications and data are executed, and the number of bits available on a processor define the memory size and space, as well as the volume of data that a processor can handle per unit of time. Typical variations of the term include 64-bit CPU, 64-bit computing and 64-bit microprocessor.Įvery microprocessor handles two key criteria: memory addresses and the corresponding data or instruction present at each memory address. Microprocessors that can handle 64 bits perform a larger number of calculations per second compared to 32-bit processors. What is a 64-bit processor (64-bit computing)?Ī 64-bit processor refers to a microprocessor that can process data and instructions in chunks of 64 bits.
