Hi, there are some incorrect readings about this GPU in AIDA64, especially the GPU clock, TMU/ROP and Shader Count. For comparison, with AIDA64, goes the screenshoot of GPU-Z that shows, i think, the correct information (minus the GPU codename, which should be Sun, not Mars)
GPU: AMD Mobility Radeon 8670M (https://www.techpowerup.com/gpudb/1950/radeon-hd-8670m), Driver: AMD Crimson Relive 17.2.1
