Snapdragon 865, the chipset to be used in the highly anticipated new flagships of 2020, will be one of the strongest chipsets of the Android side in 2020.
First of all, let’s look at the differences in core parameters between Snapdragon 865 and Snapdragon 855. There are “Three Main Factors” that we all know about performance like CPU, GPU and RAM size. Snapdragon 865 has improved significantly in these directions.
In addition to the CPU and GPU upgrades, the Snapdragon 865 is also the first SoC to support LPDDR5 (also compatible with LPDDR4x).
CPU: New A77 Architecture – 25% More Performance
From the perspective of the CPU, although the frequency of the super-large core, large core and small core is not different from the previous Snapdragon 855, but the super core and large core of the Snapdragon 865 are deeply customized based on Cortex-A77. This is also the most powerful CPU core of the Android side, and it is also the latest product of ARM. Compared with the Snapdragon 855 and Cortex-A76 used in mainstream mid-to-high-end products on the market, it is much stronger in single-core performance. In addition, the Snapdragon 865 also has twice the shared L3 cache of the Snapdragon 855.
According to official data of ARM, Cortex-A77 performs 20% more than Cortex-A76 with the same process and same frequency. The Snapdragon 865 is exactly the same frequency as the Snapdragon 855.
When we compare the Snapdragon 865 with the previous generation of Snapdragon 855/855+ with the same frequency, there is a performance improvement of 25% in single core performance and approximately 29% in multi core performance.
GPU: Still the Strongest Graphics Processor
With the rapid development of mobile games, large-scale games with high picture quality and high frame numbers place higher requirements on the overall performance of mobile phones, especially graphics processing performance. Qualcomm’s flagship SoC has always been the industry leader in this regard, and the Snapdragon 865 uses the Adreno 650 graphics processor.
Although there is almost no increase in frequency (Adreno 650 frequency is 587MHz), the increase in graphics performance from Adreno 640 to Adreno 650 is still considerable. Qualcomm officially claims to have 25% graphics performance improvement and 35% energy efficiency improvement.
After upgrading your Android version, we usually see updates on the GPU driver. GPUs can bring performance improvements after updating a new driver. However, due to differences in the development progress of different manufacturers, some models may not have the latest GPU driver upgrades. In order to solve this problem, Qualcomm and Google exclusively cooperated to develop an online driver update function for the Adreno 650. Users can manually upgrade the latest version of the Adreno GPU driver directly in the software market of manuely.
In GFXBench’s off-screen test, although the frequency is “only” 587MHz, the GPU performance of the Snapdragon 865 is still significantly higher than that of the Snapdragon 855+ with a frequency of 675 MHz.
In the more stressful GFXBench 5.0 test scenario, the situation is similar to the previous old scenarios.
Take Better Photos: The number of Pixels processed per unit has been increased 4 times
Nowadays, the camera performance of mobile phones is getting stronger and stronger, and high-pixel, multi-camera, and multi-focus cameras have become the development direction, which puts new requirements on the ISP performance of mobile phones. Snapdragon 865’s new Spectra 480, which can process 2 billion pixels per second, supports 4K HDR video shooting of 64MP photos at the same time. The powerful ISP allows the mobile phone to still have fast imaging speed in 108MP mode, HDR and night scene mode, which is crucial for the mobile phone’s camera experience.
The new ISP has a dedicated noise reduction module with motion compensation. The Snapdragon 865’s mobile phone reduces power consumption by 16%, improves texture by 18%, and can process 40% more pixels. In addition, the Snapdragon 865 also supports the HEIF format, which can save more image information, which is more efficient than traditional formats, and even supports saving depth of field information.
AI Performance: Doubled Performance, 15TOPS Computing Power
As our phones become more and more intelligent, they require stronger AI performance in the processors. Snapdragon 865 has 2 times better AI performance than Snapdragon 855. This AI Engine can give you better experience in various scenarios such as video blur, image recognition, automatic scene optimization in photos and speech recognition.
LPDDR 5 Memory
New LPDDR5 as standard, and it starts with 8GB capacity. The frequency is increased to 2750MHz, the bandwidth is 29% stronger than the previous LPDDR4x 2133MHz, and the bandwidth has reached 44GB/s. At the same time, it can also reduce the power consumption of the entire machine by about 20%.
5G network is one of the hottest topics in the mobile phone industry today. With the further improvement of LAN broadband and more and more access devices, the upgrade of Wi-Fi technology is also a top priority. The emergence of Wi-Fi 6 (802.11ax) has solved the user ’s problem of broadband and multi-device connection. It has a higher bandwidth than the common 802.11ac on mobile phones (The theoretical peak of Snapdragon 865 is 1774Mbps, which is common. Mobile phones are 833Mbps), and can better meet the needs of multi-device connection.
