The G613 has a 1 ms report rate and Bluetooth to provide multi-device connectivity.
Two AA batteries are claimed to run the keyboard for up to 18 months.
"LIGHTSPEED and POWERPLAY made the dream of untethered and uncompromised wireless performance a reality," said Ujesh Desai, vice-president and general manager of Logitech G.
The new keyboard has Logitech G's Romer-G mechanical key switches which are part of other models as well.
The company claims Romer-G switches actuate at 1.5 millimetres, 25% less than the nearest competitor.
The G613 will be available at major retailers this month at a suggested RRP of A$169.95.
