    This is a cheaper version of the Arduino Uno R3. To lower costs the in-line package of the ATMEGA328P has been changed to a flat package and the ATmega16U2 has been replaced with the CH340G USB-Serial Converter chip. The USB connector has also been replaced with a Mini-USB Socket. This version is 100% compatible with the original Arduino Uno R3.

    CH340 is a USB bus conversion chip, it can realize USB to UART interface or USB to printer interface. In serial UART mode, CH340 provides common MODEM liaison signal, used to expand UART interface of computer or upgrade the common serial device to USB bus directly

    there is no real difference between Arduino with ch340 or Arduino with 16u2 the only difference that you need to Click Here for Arduino Driver  with Ch340 whereas 16u2 doesn't need any drive because it's embedded with Arduino IDE installer

    this pic will clarify the difference between ch340 and 16u2 :
