It's 22 nanometers. 1. Since the e31220 is a processor, the number of nanometers refers to the process process, that is, the process technology used to make the chip.
22nm process refers to the minimum component size of the chip is 22 nm, indicating that the processor uses advanced process technology and has high integration and performance. 2. At present, 22nm processes are widely used in many chip manufacturing fields, including central processing units (cpus), graphics processing units (Gpus) and system chips.
This process technology can provide high performance and low power characteristics, allowing the processor to perform more computing tasks in a relatively small volume.
Therefore, the process technology used by the e31220 processor is 22 nm, which has advanced process technology and high performance.
