Our pick

Denon AVR-X6800H is the direct pick when all eleven speakers in 7.1.4 must run from the receiver. X4800H or Onkyo RZ50 can fit when a stereo power amplifier is included, with X4800H favoring seven fast HDMI sources and RZ50 including Dirac Room Correction.
Plan a 7.1.4 room by separating eleven-channel processing from built-in amplification, including any external amp the layout requires.

What matters in practice
Seven bed speakers plus four heights need eleven amplifier channels. Buy eleven inside the receiver or add a documented external pair to a nine-amplifier, eleven-processing-channel receiver.
The subwoofer is powered separately, so 7.1.4 still requires eleven full-range amplifier channels. X6800H provides all eleven internally. A receiver advertised as 9.4 can have nine amplifiers and four subwoofer outputs, which does not add up to thirteen powered main speakers. The separate amplifier and processing counts are the useful numbers.
X4800H, X3900H, CINEMA 50 and RZ50 document 7.1.4 with an external stereo amplifier. The channels assigned to that amp and the relevant menu setting vary, so choose the manual wiring diagram before running cables. Powered second zones and bi-amping can consume internal channels and are outside the simple 7.1.4 planning assumption.
One X6800H avoids another amplifier box for this layout, but its 34.4-pound chassis still needs a rated shelf and airflow. A nine-amplifier receiver plus an external stereo amp can be useful when the amp already exists. Include the second box, interconnects, trigger or power control, ventilation and license choices in the installation plan rather than comparing receiver specifications alone.
3 options

Denon, AVR-X6800H
Eleven built-in amplifiers run 7.1.4 without another power amplifier. Thirteen-channel processing, four independent sub outputs and extensive main-channel pre-outs leave room for larger installations.
Winner whenA self-powered 7.1.4 speaker layout
Thirteen-channel layouts require additional amplification and supported speaker assignments.

Denon, AVR-X4800H
A nine-amplifier, eleven-processing-channel receiver with seven fast HDMI inputs and four independent sub outputs. It suits a large source collection and an eventual external-amp expansion.
Choose instead whenAn external stereo amplifier is available and seven fast HDMI inputs or four independent sub outputs matter.
7.1.4 still requires an external two-channel amplifier.

Onkyo, TX-RZ50
Nine built-in amplifiers and eleven-channel processing support a later 7.1.4 system with an external stereo amp. Dirac Live Room Correction and a front HDMI input are included.
Choose instead whenAn external stereo amplifier is available and included Dirac plus front HDMI access are priorities.
7.1.4 needs a separate two-channel amplifier.
