Qualcomm Snapdragon 865 replaces Snapdragon 855 for 2018 as Qualcomm’s latest mobile application processor. It comes with an important increase in the hottest trends in the smartphone, gaming and photography industries.
Qualcomm Snapdragon 865 is designed on 7nm TSMC FinFET process. Overall performance increase from the 855 is around 25%. Energy efficiency is in the range of 25% also, and Qualcomm has redesigned both AI and imaging processors. Snapdragon 865 doesn’t have a 5G modem built into it, though this isn’t necessarily a big problem. This might be overlooked, considering how many other improvements were made in the 865.
Of course at the heart of every smartphone chipset is a combined CPU and GPU. You won’t find a duo that is more powerful than the Snapdragon 865 Kryo 585 CPU and the Adreno 650 GPU.
Like Snapdragon 855,the 865 also uses the Prime, Performance, Efficiency octa-core CPU configuration.
Its biggest core is the Arm Cortex A-77 clocked at 2.85 GHz, which is paired with a 512 KB L2 cache for maximum performance.
Three larger cortex A77 cores fill the core and provide a peak clock speed of 2.4 GHz and a smaller 256K L2 cache. Cortex-A77 is the most powerful CPU arm design ever. It offers more than enough power to run the heaviest mobile applications and games.
Neither Kirin 990 nor Exynos 990 have this core – they are based on the older Cortex A-77 (and M4 core specifically on M4 in the case of Exynos).
The essence of smaller energy efficiency is similar to last year’s. These are four Cortex-A55 cores with 128 KB L2 cache and 1.8 GHz clock rate.
That’s generally the same as last year’s attitude. Overall, Qualcomm promises a 25% increase in productivity and energy efficiency for this generation.
