CPU Features

• Intel and AMD are CPU chipset manufacturers/brands, producing most of the CPUs available in the market. Both companies produce high-quality CPUs; however, the differences between them are that Intel CPUs have greater performance per core, are more power efficient, and have high clock tick speeds, while AMD CPUs are less expensive, stay cooler than Intel CPUs, come with larger cache, and have better onboard graphics chips.
• i7 and i9 are brand modifiers: the greater the number, the more powerful the tasks that this CPU can perform are. Similarly, Ryzen 9 is a brand and level number of the AMD CPUs.
• 4.3 GHz is the CPU's speed. "GHz" is read as "Giga Hertz", where hertz is a unit of frequency measuring the number of clock cycles per second. During 1 clock cycle, the CPU can run up to several computer instructions, so the more cycles there are, the more instructions it can run. 4.3 Giga Hertz means that the CPU can run at least 4.3 billion of instructions per second!
• Each CPU core can run instructions in parallel and independently of other cores. Some cores can run 2 sequences of instructions (= threads) at the same time, called dual-threaded or hyper-threaded cores, while those that can run only 1 sequence at a time are singly-threaded. A CPU with 20 cores and 28 threads means 28 - 20 = 8 cores are hyper-threaded, and 20 - 8 = 12 are singly-threaded. Such a device can run at least 20 programs simultaneously!
