Our Verdict

Logitech G915 X

Logitech G915 X LIGHTSPEED

The Logitech G915 X and the Logitech G915 X LIGHTSPEED. are low-profile gaming keyboards from the same lineup. Both offer the same build quality and raw gaming performance. The only major difference is that the G915 X LIGHTSPEED has added wireless connectivity with a 2.4GHz receiver or Bluetooth. Additionally, the G915 X LIGHTSPEED is available in Linear, Tactile, or Clicky switch options at purchase, while the wired-only G915 X only has Linear and Tactile switch options.
