Nowadays, there are many projectors equipped with CPU and GPU. It’s hard to classify and tell the difference of them for beginners.

What’s CPU?

CUP refers to Central Processing Unit, which is one of the main parts of electronic devices.  Its main functions are to interpret instructions and to process data.  All operations in a device are read by the CPU instructions. It is responsible for decoding instructions and executing instructions.

Plainly speaking, it is the brain that processes all the information, responsible for more than 90% of the data in an electronic device.  The speed of its work directly affects the running speed of the whole electronic equipment.  If the brain is slow, how can the system work fast, right? 

The main global suppliers of CPU are Intel and AMD. The common CPU suppliers of home projectors are Mstar and Amlogic. For example, Mstar 6A938 and Amlogic T968.

What’s GPU?

GPU is the acronym of Graphics Processing Unit. It is a microprocessor to process images and graphics.

Its purpose is to convert the display information required by the computer system to drive, and provide line scanning signals to the display, and control the correct display of the display. Mali-T450 and Mali-G71/72 are widely used in home projectors.      

What Are the Differences?

CPU just like the commander in chief of a computing system, while GPU is the assistant which is responsible for the simple but vast arithmetical operation in terms of graphics.

CPU has relatively lower computing capability while the GPU is strong.
