When buying a computer, the processor is also one of the important basis for us to make a choice. Currently, the common CPU models are Intel I3, I5, I7, etc., both in terms of price and performance, I7 is higher than I5 and higher than I3. But do you know that these three processors are actually from the same production line, and the production cost is almost the same, why is this?
This is to start from the manufacturing process of the CPU. The raw material of the CPU is monocrystalline silicon. The single crystal silicon is processed into a cylindrical ingot, then cut into sheets, and then subjected to photocopying, etching, layering and other processes. The CPU is made, but because the production precision of the CPU is too high, the etching process cannot be perfectly controlled, and the produced CPU has a large randomness, so the cpu produced is tested and dissipated according to the performance frequency. For classification, the best effect is I7, followed by I5 and I3, so I3, I5, and I7 are not specially produced, but are classified according to the production results.
