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 Cooler Master MasterMouse MM520 and Razer Abyssus V2, 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, 7 years old, being released in the 2017, while Abyssus V2 is older, 8 years old, being released in the 2016. The production age difference is 1 year(s). This makes the MasterMouse MM520 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 Abyssus V2 mouse, MasterMouse MM520 is ~1.00 mm (or ~0.04 in) Longer, ~14.50 mm (or ~0.57 in) Wider and ~8.50 mm (or ~0.33 in) Lower, which makes it, overally, 7 mm (or 0.28 in) slightly bigger and better suiting greater hands.
Considering the weight, Cooler Master MasterMouse MM520 is 21% heavier, a difference of 21.00 g (0.05 lbs), which can be considered quite 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, MasterMouse MM520 is meant to be Right-handed while Abyssus V2 is Ambidextrous. They offer different grip, Claw grip by MasterMouse MM520 while Abyssus V2 has Claw grip, Fingertip grip; this last one can be considered more adaptable, with a number of grip possibilities equal to 2 instead of the 1 offered by the other one.
• Sensor and Latencies 🐭⏱️
Let's now compare Cooler Master MasterMouse MM520 sensor with the one of Razer Abyssus V2. The two mice share the same sensor technology, that is Optical, but different sensor model: PMW3360 equipped by MasterMouse MM520 and PMW3329 used by Abyssus V2. 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 MasterMouse MM520 provides 11900 DPI/CPI, while Abyssus V2 offers 4900 DPI/CPI, meaning that the first one has way 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, MasterMouse MM520 is offering 58% better Max Resolution, 7000 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, MasterMouse MM520 shows a better value, 50 G, a moderate difference of 20 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, MasterMouse MM520 shows a preferable value, 250 IPS, a significant difference of 150 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, the Lift Off distance of Abyssus V2 shows an higher value, 2.5 mm, a moderate difference of 0.50 mm. Anyway, MasterMouse MM520 offers adjustable lift off distance through software.
Click and Shift Latencies
Cooler Master MasterMouse MM520 has lower click latency than Razer Abyssus V2, a small difference of 0.20 ms, 2% 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 MasterMouse MM520 and Abyssus V2 shift latency. Contact us to request priority data update.
• Other Features 📎
Let's now have a look, finally, to the general features of the two mice. They are equipped with different Switch Technology, MasterMouse MM520 has Omron (20 million clicks) while Abyssus V2 has Unknown; The Feet Material is different, MasterMouse MM520 (PTFE) and Abyssus V2 (Unknown). Considering the available Number of Buttons, 6 offered by first mouse and 4 offered by the second one, a small difference of 2 that can be considered important or not depending on the utilization purpose. In the end, the features offered by Cooler Master MasterMouse MM520 are On board Memory, DPI Indicator, RGB Lighting, Customizable RGB, while Razer Abyssus V2 is giving DPI Indicator, RGB Lighting, Customizable RGB.
