Logitech G703 vs G903: Differences and Similarities


The DPI of your mouse is a measure of the sensitivity of your mouse and it stands for dots per inch.

Both the G703 and G903 have an equal range of DPI from 200 – 12,000 and so have equal sensitivity.

The performance from the use of either will be the same in terms of sensitivity and so both choices are best with respect to this.


While the weight of your mouse can give you a feeling of durability and confidence, it can also affect the maneuverability.

Lighter mice are more easily moved but can feel flimsy in the hands of a gamer and that is why a perfect balance must be maintained here.

While both mice have different weights, you have the option of adding the extra weight of 0.35oz depending on your preference.

The G703 weighs 3.77oz (107g) and the G903 weighs 3.88oz (110g). If you are a gamer who prefers lightweight mice then the G703 will be your best call.

Bear in mind that the lighter weight of G703 in no way feels flimsy but retains the feel of quality.


Over time, USB mice have had an edge over wireless mice because of responsiveness and being less prone to latency. These issues do not affect the G703 and G903 as you get a quick response rate and latency-free gameplay.

Logitech took care of these problems with their use of a PMW3366 optical sensor which provides a sensitivity range of 200 – 12,000.

The use of Lightspeed wireless connectivity ensures that gamers have a 1 ms response rate, improving response time greatly. It also takes care of the latency problem that some other mice have and all these contribute to improving your overall gaming experience.


Both mice make use of RGB lighting, providing lighting effects from 16.8 million colors. For a better gaming experience, the full spectrum lighting responds to in-game actions.

What you have to do to get the most out of this lighting setup is to combine the mouse with a G RGB keyboard and speakers for a LIGHTSYNC setup.


For gamers on a budget wanting to purchase the G series mice, the best choice for you is the G703 as it’s way cheaper than G903.

G903 is an improvement to G703 and so if you can afford it, you should get it but it doesn’t mean that G703 won’t give a wonderful performance.

Perfect Hand for Use

Most mice are made for right-handed users and the left-handed users are often neglected. Thanks to the design of G903, you could switch hands if you are ambidextrous, or use your left hand comfortably if you are left-handed. G703 is made for right-hand use only.


Both mice make use of the Pixart PMW3366 sensor which offers a minimum DPI of 200 and a maximum of 12,000.

This allows for good tracking and offers precision when taking sniper shots. You can easily choose between different DPI using the DPI toggle button.

Battery Life

The G703 and G903 both have equal battery strengths to last for 24 hours on default lighting and 32 hours on no lighting.

With POWERPLAY you do not have to connect any charger but charge wirelessly. This form of charging is supported both while you are on the mouse and off the mouse.
