3 Differences between realme C21 and realme C21Y that you need to know

realme Worldwide introduces a new smartphone for the affordable segment. The new smartphone is the realme C21Y which was officially launched in the Many countries on July 19, 2021. This cellphone had previously been on the Vietnamese market.

The momentum for the launch of the realme C21Y in Indo coincided with the opening of the new academic year 2021-2022. No wonder the Marketing Director of realme Indo, Palson Yi, stated that the realme C21Y is here for students. In this case, realme wants to provide a cellphone that is suitable for online learning activities.

If you look closely, the C21Y realm is similar to the C21 realm, which launched in Many Countries in March 2021. However, there are some minor changes that should be discussed in this article.

Techpk, has also prepared a brief review of the differences between the realme C21 and the realme C21Y which you will soon find out. Look at the specifications of the two phones as follows before entering the main discussion.

The difference between realme C21 and realme C21Y

Every new product that is launched must present something that changes. Even if the changes are not much, it is enough to make a new phone different from the previous generation. Likewise with the realme C21Y and the realme C21 whose differences we can observe below.

1. Design and Dimension

There is no striking difference in terms of design between the two phones. realme C21 and C21Y are designed with Geometric Art Design style . This design pattern is in the form of a cross line which is claimed by realme to be able to reduce fingerprint stains on the back cover of the cellphone.

The contrasting difference in the lines creates a visual effect like two triangles facing each other. You will also see the position of the buttons, ports, fingerprint sensor of both phones are exactly the same. In fact, the realme C21 and C21Y both passed the high reliability certification from TUV Rheinland.

This certification guarantees that both phones can be used in the best conditions for at least three years from the date of purchase. Well, if you look closely, it turns out that there are still things that are different from the appearance of these two phones. The difference lies in the rear camera module.

For realme C21, there are four circles that are closely spaced between circles. Three circles of which are the camera lens, while the remaining one is the flash. This flash light is located in the lower right corner circle.
Unlike the realme C21Y, the number of circles is the same as four. However, the diameter of the circle is slightly smaller. As a result, the distance between the circles becomes wider. Then, the flash is now placed in the upper right corner.

It is not known what is the reason for realme reducing the diameter of the circle and moving the flash light position on the realme C21Y. However, this change is believed to not change the quality of the shots.

The thing that is different about the physical aspects of the two phones is the dimensions. Although they have a similar shape, the size of the two is not the same. realme is slightly thinner with dimensions of 165.2 x 76.4 x 8.9 mm. It is also lighter in weight: 190 grams.

Meanwhile, the Realme C21Y is shorter and thicker with dimensions of 164.5 x 76 x 9.1 mm. It is also heavier: 200 grams. Well, this size difference makes the screen-to-body ratio of the two phones also change. Given that the embedded screen span is both 6.5 inches.

GSM Arena noted that the realme C21Y was a little more efficient at using its body to cram the screen. The screen-to-body ratio is 81.6%. While the realme C21 has a ratio of 80.8%.

2. Chipset

You may already know that the realme C21Y uses a different SoC ( System on a Chip ) from the realme C21. Yes, realme C21Y uses a SoC from UNISOC (read: UNI - SoC) named Tiger T610. While the Realme C21 uses the MediaTek Helio G35.

At first glance about UNICOC, this SoC manufacturer from China is actually not a new player. The reason is, their concoction chipsets have been used by various vendors, Samsung is one of them. People know him with Spreadtrum Communications.
However, in 2013 Tsinghua Unigroup (a kind of SOE in China) acquired Spreadtrum shares. Then there was a change in the name of the company and its products to UNISOC. The UNISOC operates fabless . That is, they design and sell the SoC themselves, but leave the manufacturing process to another company.

Back to the UNISOC Tiger T610 problem that the Realme C21Y uses. According to Wikimovel, this chipset is a mid-range SoC that was launched in 2019. The Tiger T610 has a profile as an eight-core SoC built with a 12nm fabrication process.

It contains two Cortex A75 fast cores and six Cortex A55 power efficient cores. All have a speed of 1.8 GHz. Not only that, there are many other components that are assembled in this SoC. One of them is the Mali-G52 GPU which can work at speeds up to 850 MHz.

What about the Helio G35 that realme C21 relies on? The SoCs introduced in the second quarter of 2020 are indeed both made with a 12 nm fabrication process. However, the CPU configuration and architecture it uses is older.

The Helio G35 contains four Cortex A73 fast cores and four Cortex A53 efficiency cores. The fast cores are set at a peak speed of 2.3 GHz, while the efficiency cores can run up to 1.8 GHz. For graphics, this SoC relies on the PowerVR GE8320 GPU with a frequency of 680 MHz.

3. Benchmark Score

Benchmark scores (benchmarks) can't be someone's main reference when buying a cell phone. Because, benchmark scores are measured based on the performance of an Mobile Phone at one time. While the experience of using an Mobile Phone can be felt if you try it in a short time.

Even so, benchmark scores can be used as the first indication of what kind of performance the phone provides. Let's start with AnTuTu 8 which is the most popular benchmarking app in the world.

According to Chipguider, the UNISOC Tiger T610 belonging to realme C21Y recorded an AnTuTu 8 score of 169,746 . While the Helio G35 belonging to realme C21 scored 114,486, according to nanoreview.

Head over to GeekBench 5 for a look at the specific CPU capabilities. The Tiger T610 scored 278 on the singlecore test and 917 on the multicore test . While the Helio G35 scored a singlecore score of 172 with a multicore of 988.
For GPU capabilities, let's take a look at the GPU test scores on AnTuTu 8 for each SOC. The Tiger T610 got a GPU score of 56,412, while the Helio G35 got a GPU score of 13,274.

Based on the scores above, realme C21Y has the potential to have better performance than realme C21. Whether it's for opening and closing applications (determined by singlecore score ) or playing games (GPU score).

Conclusion

The most obvious difference between the realme C21 and C21Y is in the SoC. realme C21Y uses the UNISOC Tiger T610 SoC which makes it potentially have a slightly more stable performance. In addition, this cellphone will also be more comfortable to hold because it weighs 10 grams less than the realme C21.

For those of you who haven't tried the C21 realm, it's a good idea to immediately make a choice on the C21Y realm. Because, at a similar price, you can get an increase in terms of performance and comfort.
