A central processing unit (CPU), also called a central processor, main processor, or just processor, is the most important processor in a given computer. [1] [2] Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations.
In computing and computer science, a processor or processing unit is an electrical component (digital circuit) that performs operations on an external data source, usually memory or some other data stream. [1]
The following is a partial list of Intel CPU microarchitectures. The list is incomplete, additional details can be found in Intel's tick–tock model, process–architecture–optimization model and Template:Intel processor roadmap.
CPU may also refer to: Science and technology. Carboxypeptidase B2, a human enzyme; Critical Patch Update, software updates in Oracle products such as Oracle ...
Includes CPU cores, GPU and Northbridge in the same chip. Llano was the first design which implemented it. Fusion was later re-branded as the APU. AMD Bobcat Family 14h – a new distinct line, which is aimed in the 1 W to 10 W low power microprocessor category. Ontario and Zacate were the first designs which implemented it.
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
Intel Haswell Core i7-4771 CPU, sitting atop its original packaging that contains an OEM fan-cooled heatsink. This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings. Concise technical data is given for each product.
CPU-Z is more comprehensive in virtually all areas compared to the tools provided in the Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.
