Samsung received a lot of hate due to the performance disparity between last year's Exynos 990 and the Snapdragon 865 which were used in Samsung flagships. The Exynos not only lacked performance in CPU and GPU department, but also was not power efficient and had thermal issues compared to the Snapdragon 865. Even the Snapdragon model clicked better pictures due to its better Image Signal Processor (ISP).

Samsung has listened to our complaints last year and has introduced the new Exynos 2100 this year in their S21 series. The chip has the same cores and core configuration as the Snapdragon 888, but all the cores are clocked at higher frequencies than the 888. They are using the latest Mali G78 GPU from ARM for graphics processing.

In an in-depth testing of both the Snapdragon and Exynos models of the S21 ultra by Gary from SpeedTestG, the results were quite interesting. The Exynos 2100 wins in terms of CPU performance and the reason could be the higher clock speeds compared to the 888. But in mixed GPU and CPU performance the Mali G78 could only grab 27 fps while the Snapdragon model managed 35 fps. 

This continues as the Adreno 660 GPU in the Snapdragon 888 overtakes the Exynos 2100 in the GPU test by 7 seconds to complete the test faster than the Exynos 2100 model. The Snapdragon managed to complete the CPU test in 34.7s, mixed CPU and GPU tests in 18.1s and the GPU test 26.1 seconds bringing its total time to 1min and 19 s. 

The Exynos on the other hand completed the CPU test in 33.4s, mixed in 20.1s and GPU test in 33.6s. These results clearly shows that the Mali G78 is not as powerful compared to the Adreno 660.

Apple Airpods Max vs Sony wh1000-xm4

When it comes to over-hear noise cancelling headphones, Sony leaded the industry with their wh1000 series. And now, the competition just got more stiffer as Apple introduced the Airpods Max. The latest and greatest noise cancelling king the wh1000-xm4 costs $350, but can be available for around $300, but Apple just dropped the Airpods Max with a price tag of $550, which got people thinking about it. Lets compare them to see that if Sony will remain the king or does Apple take the crown? Apple AirPods Max takes it from Sony in terms of build quality. Apple uses high quality stainless steel for the body, aluminum for the earcups and memory foam for the headband. They are superior materials in every way compared to plastic used in Sony. But dont take it wrong, the xm4 is also really built well and is really comfortable to use. In terms of sound quality Apple uses custom built 40mm drivers and they sound extremely good. The H1 chip inside both earcups provide computational audio with adapt

Qualcomm and Google announced their collaboration to simplify and bring 4 years of Android updates to smartphones powered by Qualcomm Snapdragon processors. Under Project Treble devices running on Snapdragon chipsets (from SD888 onwards) will receive security updates and new android versions for the next four years.  Project Treble will enable OEMs to upgrade their devices to the latest Android versions without worrying about Qualcomm Snapdragon chipset specific software. This is a huge leap in terms of android updates which is not always guaranteed in the Android world. OnePlus provides android updates to their devices for 3 years and recently Samsung also started providing 3 years of updates for their flagship devices. This will be divert some Apple customers into Android space because from the coming year Android smartphones with Snapdragon chipsets will be getting long term software support just like iPhones and increase the longevity of Android smartphones from 1-2 years to 4+ wit
