According to your description, I suggest you refer to the following information:
AU indicates that the machine adopts AMD processor and the graphics card is an integrated graphics card; TX means that the machine uses an intel processor and the graphics card is a discrete graphics card. note:
A indicates that the machine uses amd's cpu.
T means that the machine uses Intel's cpu.
U indicates that the machine is an integrated graphics card with UMA architecture.
X indicates that the machine uses a discrete graphics card.
Therefore, generally speaking, the product names of HP home notebooks end with TU, TX, AU and AX.
I hope the above reply can help you.
