It could also be an issue with what ASUS said was included in the laptop.

Try update it and see if it still says 280X after. GPU-Z might need an update to update its database (they are on 2.10 now, 0.8.2 is 3yrs old now). Check GPU-Zs database, the only R9 M2XX chip with 768 shaders is the 270X.

The big issue with mobile chips is that they are all adapted to suit the laptop manufacturer's requirements, but that laptop has a Saturn Pro in it based on the PCI ID and the number of shaders. They don't have a listing for an M270X (Saturn Pro) with 4 GB VRAM as you have, so they likely defaulted to the M280X, even though that's a Saturn XT chip. That aligns with GPU-Z's description of the M270X ( ), as the M280X has 896 shaders ( for 2GB and for 4GB). Note that there are 768 shaders reported.
