Graphical Vs Comparison
Wow! The Monkeys 🐒 learnt to make Graphs!
| Physical Characteristics (mm, grams) |
|
| Sensor Characteristics (0 ➡ 100%) (worse ➡ better) |
|
| Latency Characteristics (0 ➡ 100%) (worse ➡ better) |
|
| Other Features (0 ➡ 100%) (worse ➡ better) |
| Graphs Description | The Physical Characteristics comparison is just a viewable representation of the devices' length, width, height and weight. Sensor, Latency and Other Features are, instead, computed within the range 0-->100, taking into account if the variable is getting better with the increase of its value (e.g the highest max DPI, the better it is) or vice versa (the lowest Click Latency, the better); for example, a score of 50 for both devices means they are equal, scores of 70 and 30 mean that first one better. So, the data are homogeneous to provide immediate meaning, higher bar(s) means better value(s). An empty graph means that there is not enough data to compute that comparison (one value or both are missing). |

Final Vs Words
Aiding our visitors to the final choice between the mice.
This final paragraph will help you in the decision making process, between Razer Cobra Pro and Logitech G703 Lightspeed, and in selecting the mouse that is performing better and best suits your needs. We are aware that every user has own needs and preferences, due to this each mouse could be better for some features and worse for other ones. The purpose of the text is to highlight this possibility and generate an "overall score" for a purchase decision.
First of all, both mice share the same utilization aim, Gaming mouse. The first one is younger, 1 years old, being released in the 2023, while G703 Lightspeed is older, 5 years old, being released in the 2019. The production age difference is 4 year(s). This makes the Cobra Pro kind of more attractive in terms of freshness.
• Dimensions, Weight, Ergonomy 📐⚖️🫳
When it comes to evaluate mice dimensions, you should take into consideration the size of your hand and check if it would properly fit it or not. In this case, you should check which mice would be the fittest. Compared to G703 Lightspeed mouse, Cobra Pro is ~4.40 mm (or ~0.17 in) Shorter, ~5.50 mm (or ~0.22 in) Narrower and ~4.90 mm (or ~0.19 in) Lower, which makes it, overally, 14.8 mm (or -0.58 in) moderately smaller and better suiting tinier hands.
Considering the weight, Razer Cobra Pro is 19% lighter, a difference of 18.00 g (0.04 lbs), which can be considered moderately significant. We do not express a particular preference for heavier or lighter mice, being this a completely personal objective preference. However, G703 Lightspeed offers weight personalization (addable weights or editable shape) while Cobra Pro does not.
Regarding the Ergonomy, Cobra Pro is meant to be Ambidextrous while G703 Lightspeed is Right-handed. They offer the same grip, Palm grip, Claw grip, Fingertip grip; the degree of adaptability is the same and equal to 3.
• Sensor and Latencies 🐭⏱️
Let's now compare Razer Cobra Pro sensor with the one of Logitech G703 Lightspeed. The two mice share the same sensor technology, that is Optical, but different sensor model: Focus Pro 30K equipped by Cobra Pro and Hero 25k used by G703 Lightspeed. It is very important to say that, although tech and model sometimes coincide, the assembly and composition of interior circuits might result in different specs and latencies.
Resolution, Max Acceleration and Max Tracking, Polling Rate and Lift Off
The mice offer different resolution range (DPImax - DPImin), the Cobra Pro provides 29900 DPI/CPI, while G703 Lightspeed offers 25500 DPI/CPI, meaning that the first one has larger range. Consider picking up the sensitivity range that mostly suits your needs, depending on the aim (Gaming/Business) but also the kind of game you are going to use it mostly (e.g. FPS is different than RTS or MOBA). If you need a higher precision mouse, meaning that for the same length of shift the mouse will recognize more movement, "reading" more dots per inch and, in other words, will move faster on the screen, Cobra Pro is offering 15% better Max Resolution, 4400 More DPI/CPI.As for the Maximum Acceleration, which measures the maximum pull force in G(s) that the sensor can trace before inconsistencies occur, Cobra Pro shows a better value, 70 G, a significant difference of 30 G. Going on, taking into account the Maximum Tracking Speed, the velocity (inches per second) that the mouse can move at before it starts to loose track and cause anomalies, Cobra Pro shows a preferable value, 750 IPS, a great difference of 350 IPS. Take into account that max G and max IPS mostly affect activities requiring very fast mouse shift, together with the shift latency that we will analyse further in this section.
Cobra Pro has a Polling Rate of 8000 Hz, in other words it reports data to computer 1 time every 0.13 ms, while G703 Lightspeed is characterized by 1000 Hz or an input every 1.00 ms, making this last one having 88% worse Polling Rate. Lastly, Cobra Pro and G703 Lightspeed share a Lift Off distance of 1.2 mm, above this one they will not work accurately. Anyway, they offer adjustable lift off distance through software.
Click and Shift Latencies
Razer Cobra Pro has lower click latency than Logitech G703 Lightspeed, a not so small difference of 2.45 ms, 46% better Click Latency, which can be evaluated slightly significant, in terms of compared performance. Anyway, we feel it is important to underline that the differences in latencies are often more perceptible from the machine's point of view rather than human's, reducing the real impact of these values and deviations. The Cobra Pro has lower shift latency than G703 Lightspeed, a not so small difference of 1.95 ms, 22% better Shift Latency, which can be evaluated slightly significant, in terms of comparison of values.
• Other Features 📎
Let's now have a look, finally, to the general features of the two mice. They are equipped with different Switch Technology, Cobra Pro has Optical Gen-3 while G703 Lightspeed has Omron; moreover, the Switch lifespan of first mouse is 90 millions clicks while the second is 50 millions clicks, 44% better Lifespan, a difference of 40 millions clicks that can be evaluated very significant. The Feet Material is better for Cobra Pro, being this Virgin Grade PTFE. Considering the available Number of Buttons, 8 offered by first mouse and 6 offered by the second one, a small difference of 2 that can be considered important or not depending on the utilization purpose. The first one has a declared battery time of 100h (type: Lithium polymer 420 mAh), the second one has a duration of 60h (type: Unknown) meaning a difference of 40h. In the end, the features offered by Razer Cobra Pro are On board Memory, RGB Lighting, Customizable RGB, while Logitech G703 Lightspeed is giving On board Memory, DPI Indicator, RGB Lighting, Customizable RGB.
