It looks like Samsung will be changing the games with microprocessors again. They recently announced their newest processor, using the new GAA, or Gate All Around, technology. Essentially, they will change the way transistors inside microprocessors are made; making them smaller and tighter packed, which allows for an increase in effective power while decreasing the energy needed to operate it.
Set to begin testing in 2020, with mass-production in 2021, GAA will mean that modern technology will get more powerful, and operate faster, while not putting such a drain on the batteries in cellphones, cars, and other things that have a computer telling them what to do. While it will mean that the technology using these processors will be more expensive for the first few years due to the increased price of production, it seems like the performance will outweigh the cost. Faster phones, with better battery life, sounds like an awesome thing to come.
Transistors are a crucial key to any modern technology. The invention of the transistor is what opened the door for microchips and digital memory. Transistors act as an amplifier for power and as a gate to tell the microchip, or processor, what they are supposed to be doing. As transistors turn on and turn off, it directs power to particular locations, and that acts as the instruction. Think of binary; on, off, on, off.
The key to the new processors will be the proximity of the transistors within the processors. Right now, Samsung's transistors are 7nm(nanometers) apart. The closer the transistors are to one another, the faster energy travels from one to the next, and the greater the performance of the processor is. The GAA transistors are going to be 3nm apart, which will be revolutionary to the current technology. With them being placed so closely, the size of each processor can be reduced. That will allow for smaller, more powerful devices; or, will allow for even more powerful devices utilizing the existing chassis'.
