Today, Xiaomi introduced the budget devices Redmi 9A and Redmi 9C. The first is based on the SoC MediaTek Helio G25, the second is Helio G35. These platforms were also announced today, so let's figure out what it is.
So SoC are very similar to each other. Both are manufactured using a 12-nanometer process technology, both contain an eight-core CPU with old Cortex-A53 cores, both received a PowerVR GE8320 GPU.
The first difference is the frequencies. The Helio G25 processor runs at 2 GHz, the Helio G35 at 2.3 GHz. The GPU in the first case has a frequency of 650 MHz, in the second – 680 MHz.
The second difference is the supported screen resolution. For the younger platform it is HD +, for the older one – Full HD +, but this is clearly an artificial separation, because it is technically not justified.
Otherwise, there are no significant differences. Both platforms are capable of encoding 1080p / 30fps video, both support LPDDR3 RAM, LPDDR4x up to 6 GB and eMMC 5.1 flash memory, both have an LTE Cat4 modem. At the same time, which is also important, both support Wi-Fi 5.
There is no direct data on performance yet, but there is one caveat, which, of course, is not officially indicated anywhere. The fact is that Helio G25 in terms of parameters is a complete copy of Helio P22. There is not a single difference in the specifications on the site. And the capabilities of Helio P22 are familiar to us. And Helio G35 differs only in slightly higher frequencies. That is, look at the tests, for example, Realme C2 or Nokia 3.1, and you will understand what Xiaomi new products are capable of. Unless, perhaps, some proprietary "gaming" technologies of MediaTek will allow new platforms to show themselves a little better in games, but this is not accurate.
