All MX, T, M linecards use Freescale PQ3 family processors. MX80 control-plane
as well.
Freescale is phasing out PQ3 and MX104 uses QorIQ in control-plane and in
'linecard'.

Exact model for MX80 is 8572 and MX104 is P5021

MX104 doubles the DRAM of control-plane from MX80's 2GB to 4GB.

Agreed. JunOS is very control-plane demanding architecture, it requires lot of
power, on same CPU IOS-XE will fly, which is architecturally quite comparable.
