The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), the first personal computers (PCs) to arrive throughout the 1970s and 1980s had clock rates measured in megahertz (MHz), and in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz).

Some Xeon Phi processors support four-way hyper-threading, effectively quadrupling the number of threads. [1] Before the Coffee Lake architecture, most Xeon and all desktop and mobile Core i3 and i7 supported hyper-threading while only dual-core mobile i5's supported it.
The processor was a significant evolution in the x86 architecture, extending a long line of processors that stretched back to the Intel 8008. The 386 was the central processing unit (CPU) of many workstations and high-end personal computers of the time.
In March 2006, Dell introduced the D620 (and the D820), its first business-oriented notebook with a dual-core processor available. The D620 marked the transition from strictly 32-bit processing to opening-up the potential to run 64-bit operating systems and applications.

Upgrade CPU or GPU: If your computer's processor or graphics card is outdated or underpowered, upgrading to a faster model can improve performance, especially for CPU or GPU-bound tasks.
The most notable difference between this laptop and its predecessor is the 1520 model's dedicated graphics card, which the 1525 model did not have. Some believe that this was an attempt by Dell to appeal to a wider market of computer consumers. In a 2008 processor speed test, the Inspiron 1525 placed 14 out of the 18 tested computers. [6]
