Last week, Xiaomi’s sub-brand Redmi successfully launched their first gaming phone, The Redmi K40 Gaming Enhanced Edition in China. The device is powered by MediaTek's latest flagship SoC, the  Dimensity 1200. Many of you would be wondering how the vanilla K40 differs from its "Gaming Edition " brother in terms of performance? 

For those who don't know, the Redmi K40 was launched last February alongside K40 Pro & K40 Pro Plus. Qualcomm's Snapdragon 870 chipset is powering the vanilla K40. Snapdragon 870 is a newly announced flagship SoC from Qualcomm and is 5G capable. In terms of power, it lies between the Qualcomm Snapdragon 865+ and 888 processors. So you might be wondering which K40 variant aka chipset will be better for gaming & overall performance? & today we will be comparing the  Dimensity 1200 ( Redmi K40 Gaming Enhanced Edition) against Snapdragon 870 (Redmi K40). 

Here is the overview of both chipsets.

Transistor Size

The Snapdragon 870 is a 7nm SoC similar to its predecessor – Snapdragon 865 Plus. On the other hand, MediaTek is utilizing TSMC's  6nm process which is indeed smaller.

It is well known that a smaller transistor size brings an improvement in performance and power efficiency, and as you can see the Dimensity 1200 SoC has a smaller transistor size, so it wins this round.

CPU Performance

Both chipsets have an 'Octa core' design and they both feature the same "1 + 3 + 4" core configuration. But they are very different in terms of the core architecture.

The Snapdragon 870 is essentially an overclocked Snapdragon 865 Plus SoC which itself is an overclocked version of  Snapdragon 865. So essentially, you can say Snapdragon 870 is a Snapdragon 865 Plus Plus. Like its siblings, you get the same core config but at a greater clock speed. It has a prime Cortex-A77 core which clocked at 3.2GHz. Its other performance cores are also the same Cortex-A77 clocked at 2.42GHz while the power-efficient cores are Cortex-A55 cores clocked at 1.8GHz.

The Dimensity 1200 has the more powerful and efficient Cortex-A78 cores for performance as the prime one being Cortex-A78, which clocked at 3.0 GHz. Additionally, 3 more Cortex-A78 cores with a frequency of 2.6 GHz and 4 energy-efficient Cortex-A55 cores operating at a frequency of 2.0 GHz. ARM claims that the Cortex-A78 flaunts a 20% improvement in performance over the Cortex-A77 at the same power consumption. This gives it a significant improvement over the Snapdragon 870 which uses the older Cortex-A77 cores.


Like Snapdragon 865 duo, the Adreno 650 is the GPU handling the graphics of Snapdragon 870. Qualcomm didn’t claim that it has increased the clock speed for the Snapdragon 870's GPU, so we will consider the GPU performance is consistent with that of the Snapdragon 865 Plus. Which is nothing to sneeze at.

The Mali-G77 MC9 (9 cores) GPU is responsible for graphics processing & game at great efficiency in The Dimensity 1200 SoC. This is not ARM’s most powerful GPU, the Mali-G78 has that crown. MediaTek states that the GPU has received a performance bump of 13% compared to that of the Dimensty 1000 Plus.

This SoC has received support for MediaTek HyperEngine 3.0 technology, which aims to boost performance in games.

The Adreno 650 is a  very commendable GPU, and it is well known that Adreno 650 is more powerful than the Mali-G77 MC9 GPU found on Dimensity 1000 Plus. However, since MediaTek insists that the GPU inside the Dimensity 1200 flaunts a 13% improvement in performance over that of the Dimensity 1000+, then the GPU performance gap between the Snapdragon 870 and Dimensity 1200 should be more inadequate or even none.

The Snapdragon 875 SoC has support for QHD+ displays at a 144Hz refresh rate and 4K displays at a 60Hz refresh rate. Where the Dimensity 1200 supports QHD+ displays at a highest refresh rate of 90Hz which can go all the way up to 168Hz for 1080p panels.


Snapdragon 870 & Dimensity 1200 both SoC are incredibly powerful. I hope my in-depth analysis is made that obvious. I covered the 3 most important aspect of an SoC, so you would understand which is better than other in what aspect. In my eyes, Dminsity 1200 is the clear winner here, traditionally, Qualcomm's chip is more expensive than MediaTek's. That means you will find Dimensity 1200 in a more well-rounded phone with a cheaper price tag. This is what the Redmi K40 Gaming Enhanced Edition compares to vanilla K40.

I hope you like this instance comparison. Hit me in the comment if you have any questions.
