I'll teach you a simple method. 1. Use cpu-z software motherboard, and the serial number, product id, manufacturer information, factory date and so on can be seen in cpuz software. 2. There are no fakes in CPU, but the difference between boxed bulk es can also be detected by cpuz. Now, some profiteers can sell single-core 4+ dual-core

3. Graphics cards can be viewed by gpu-z with reference to the graphics card parameters published online and the comparison on CPU-Z. Otherwise, the authenticity can be distinguished.
