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 Corsair M55 RGB Pro and Thermaltake Tt E-sports Iris, 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, 5 years old, being released in the 2019, while Tt E-sports Iris is older, 6 years old, being released in the 2018. The production age difference is 1 year(s). This makes the M55 RGB Pro 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 Tt E-sports Iris mouse, M55 RGB Pro is ~1.40 mm (or ~0.06 in) Longer, ~11.45 mm (or ~0.45 in) Narrower and ~1.00 mm (or ~0.04 in) Lower, which makes it, overally, 11.05 mm (or -0.44 in) moderately smaller and better suiting tinier hands.
Considering the weight, Corsair M55 RGB Pro is 30% lighter, a difference of 37.00 g (0.08 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, M55 RGB Pro is meant to be Ambidextrous while Tt E-sports Iris is Right-hand. 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 Corsair M55 RGB Pro sensor with the one of Thermaltake Tt E-sports Iris. The two mice share the same sensor technology, that is Optical, but different sensor model: PMW3327 equipped by M55 RGB Pro and PMW3325 used by Tt E-sports Iris. 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 M55 RGB Pro provides 12200 DPI/CPI, while Tt E-sports Iris offers 4600 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, M55 RGB Pro is offering 60% better Max Resolution, 7400 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, M55 RGB Pro shows a better value, 30 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, M55 RGB Pro shows a preferable value, 220 IPS, a significant difference of 120 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.
M55 RGB Pro has a Polling Rate of 1000 Hz, in other words it reports data to computer 1 time every 1.00 ms, while Tt E-sports Iris is characterized by 2000 Hz or an input every 0.50 ms, making this last one having 50% better Polling Rate. Lastly, the Lift Off distance of M55 RGB Pro shows an higher value, 2.5 mm, a moderate difference of 0.50 mm. Anyway, they do not offer adjustable lift off distance through software.
Click and Shift Latencies
Corsair M55 RGB Pro has higher click latency than Thermaltake Tt E-sports Iris, a consistent difference of 4.30 ms, 40% worse Click Latency, which can be evaluated 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 M55 RGB Pro and Tt E-sports Iris 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 the same Switch Technology, Omron; moreover, the Switch lifespan of first mouse is 50 millions clicks while the second is 20 millions clicks, 60% better Lifespan, a difference of 30 millions clicks that can be evaluated very significant. The Feet Material is the same, 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. In the end, the features offered by Corsair M55 RGB Pro are On board Memory, DPI Indicator, RGB Lighting, Customizable RGB, while Thermaltake Tt E-sports Iris is giving On board Memory, DPI Indicator, RGB Lighting, Customizable RGB.
