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 Asus ROG Spatha X and Logitech G903 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, 3 years old, being released in the 2021, while G903 Lightspeed is older, 5 years old, being released in the 2019. The production age difference is 2 year(s). This makes the ROG Spatha X a bit 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 G903 Lightspeed mouse, ROG Spatha X is ~7.00 mm (or ~0.28 in) Longer, ~22.00 mm (or ~0.87 in) Wider and ~5.00 mm (or ~0.20 in) Higher, which makes it, overally, 34 mm (or 1.34 in) way bigger and better suiting greater hands.
Considering the weight, Asus ROG Spatha X is 35% heavier, a difference of 58.00 g (0.13 lbs), which can be considered very significant. We do not express a particular preference for heavier or lighter mice, being this a completely personal objective preference. Anyway, both mice does not offer weight personalization .
Regarding the Ergonomy, ROG Spatha X is meant to be Right-handed while G903 Lightspeed is Ambidextrous. They offer different grip, Palm grip by ROG Spatha X while G903 Lightspeed has Palm grip, Claw grip, Fingertip grip; this last one can be considered more adaptable, with a number of grip possibilities equal to 3 instead of the 1 offered by the other one.
• Sensor and Latencies 🐭⏱️
Let's now compare Asus ROG Spatha X sensor with the one of Logitech G903 Lightspeed. The two mice share the same sensor technology, that is Optical, but different sensor model: PMW3370 equipped by ROG Spatha X and Hero 25k used by G903 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 ROG Spatha X provides 18900 DPI/CPI, while G903 Lightspeed offers 25500 DPI/CPI, meaning that the last one has larger range. Consider picking up the one having 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, G903 Lightspeed is offering 26% better Max Resolution, 6600 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, ROG Spatha X shows a better value, 50 G, a small difference of 10 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, they have the same spec of 400 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.
They have a Polling Rate of 1000 Hz, in other words they report data to computer 1 time every 1.00 ms. Lastly, ROG Spatha X and G903 Lightspeed share a Lift Off distance of 1.2 mm, above this one they will not work accurately. Anyway, G903 Lightspeed offers adjustable lift off distance through software.
Click and Shift Latencies
Asus ROG Spatha X has lower click latency than Logitech G903 Lightspeed, a small difference of 0.70 ms, 14% better Click Latency, which can be evaluated not really 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. At the moment there is no available data to compare the mice shift latency, since the data of ROG Spatha X is missing. Contact us to request priority data update. However, G903 Lightspeed has a shift latency of 8.5 ms which can be considered quite decent, compared to a medium quality mouse.
• Other Features 📎
Let's now have a look, finally, to the general features of the two mice. They are equipped with different Switch Technology, ROG Spatha X has ROG Micro Switch while G903 Lightspeed has Omron; moreover, the Switch lifespan of first mouse is 70 millions clicks while the second is 50 millions clicks, 29% better Lifespan, a difference of 20 millions clicks that can be evaluated very significant. The Feet Material is the same, PTFE. Considering the available Number of Buttons, 12 offered by first mouse and 11 offered by the second one, a small difference of 1 that can be considered important or not depending on the utilization purpose. The first one has a declared battery time of 67h (type: Lion), the second one has a duration of 140h (type: LiPo) meaning a difference of 73h. In the end, the features offered by Asus ROG Spatha X are On board Memory, DPI Indicator, RGB Lighting, Customizable RGB, while Logitech G903 Lightspeed is giving On board Memory, DPI Indicator, RGB Lighting, Customizable RGB.
