Meh...
So the Panther Lake 'high end' has a 'b390' iGPU with unknown 'Xe3' GPU cores and
the Panther Lake 'medium end' has a 'b370' iGPU with 10 'Xe3' GPU cores followed by the APU THIS article is about that has an unknown iGPU with a mere FOUR (4) 'Xe3' GPU cores.
At introduction Panther Lake APU's might of been broken into TWO distinct groups, those with 'X' in the name that have GOOD iGPU's (ie: the b390) and those WITHOUT the 'X' in the name that have blah/meh iGPU's.
Please try to HELP decode the scrambled Intel Marketing nonsense rather than make it more confusing. Some Panther Lake APU's are far more interesting than others.
