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.
Perform an SMX function. The leaf function to perform is given in EAX. [t] Depending on leaf function, the instruction may take additional arguments in RBX, ECX and EDX. Usually 0 [u] Conroe/Merom, WuDaoKou, [107] Tremont: RDTSCP Read Time Stamp Counter and Processor ID. RDTSCP: 0F 01 F9: Read Time Stamp Counter and processor core ID. [v]
A CPU cache [71] is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core , which stores copies of the data from frequently used main memory locations .
If based on the von Neumann architecture, they contain at least a control unit (CU), an arithmetic logic unit (ALU), and processor registers. In practice, CPUs in personal computers are usually also connected, through the motherboard , to a main memory bank, hard drive or other permanent storage , and peripherals , such as a keyboard and mouse .
Intel A80386DX-20 CPU die image. The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture. Pre-production samples of the 386 were released to select ...
A CPU socket is made of plastic, and often comes with a lever or latch, and with metal contacts for each of the pins or lands on the CPU. Many packages are keyed to ensure the proper insertion of the CPU. CPUs with a PGA (pin grid array) package are inserted into the socket and, if included, the latch is closed.
It may have its own internal control sequence unit (not to be confused with a CPU's main control unit), some registers, [2] and other internal units such as an arithmetic logic unit, [3] address generation unit, floating-point unit, load–store unit, branch execution unit [4] or other smaller and more specific components, and can be tailored ...
