Power consumption between Agilex3 and Microchip Polarfire FPGA

Microchip claim their FPGA has lower power consumption than SRAM based FPGA ,   no matter how advanced node used for Altera. is there an official feeback to those claim ? if customer design is battary powered and really care power consumption rather than fabric or tranciever performance, what is the advantage of Agilex 3 comparting to Microchip Smartfusion and Polarfire in power consumption. has Altera done any comparision regarding power consumption ? Any comparision data availalble to share?

Microchip FPGAs and SoC FPGAs consume up to 50% lower total power than competitive FPGAs. Our nonvolatile process delivers FPGA families that are live at power-up with minimal in-rush current, and significantly lower leakage than SRAM-based alternatives
