Further, a "cumulative clock rate" measure is sometimes assumed by taking the total cores and multiplying by the total clock rate (e.g. a dual-core 2.8 GHz processor running at a cumulative 5.6 GHz). There are many other factors to consider when comparing the performance of CPUs, like the width of the CPU's data bus , the latency of the memory ...
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.

As of 2018, many Intel microprocessors are able to exceed a base clock speed of 4 GHz (Intel Core i7-7700K and i3-7350K have a base clock speed of 4.20 GHz, for example). In 2011, AMD was first able to break the 4 GHz barrier for x86 microprocessors with the debut of the initial Bulldozer based AMD FX CPUs. In June 2013, AMD released the FX ...

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 .
A 3 GHz model of the Intel Pentium 4 processor that incorporates Hyper-Threading Technology [7]. Hyper-Threading Technology is a form of simultaneous multithreading technology introduced by Intel, while the concept behind the technology has been patented by Sun Microsystems.
