Doh! But yes. And like the 7D2, the 80D predecessor also used the same older fab process. Again I think this is probabaly going to be more a function of the new ADC (the more I think about it) because the multiple channels could (I suppose) be segregated via a firmware switch to read out each sub-pixel independently, whereas the older ADC designs (even with the DPAF) perhaps can not.
that's not entirely known for sure .. as an example the 70D and 7D Mark II QE jumped significantly, and dual pixel itself requires the splitting of the PD in half, which means that it probably required a tighter geometry.
keep in mind that canon didn't get it's ADC sensor patents approved until 2014-15 that really is independent of the fab process.
