This is improved Arduino Uno R3 is one of the latest version of Arduino Uno with an on-board CH340 usb - serial converter chip. This provides you a cheaper opportunity to get started with Arduino boards. The microcontroller model of this board is the same as the original one (Atmega328). The only difference between microcontrollers is ther package. The original one has a DIP package but the clone one has SMD package microcontroller. Its more powerful as compare to dip version.
