A closer look at the Qualcomm Snapdragon 865 chip



Yesterday, at its annual technology summit Qualcomm announced the name of its next flagship mobile processor – the Snapdragon 865 – and today we finally get a bit more details on all the new enhancements and improvements Qualcomm has in its shining new chip.

By the beginning of 2020, 5G is a clear focus for upcoming mobile devices. As a result, the Snapdragon 865 naturally supports both mmWave and sub-6Ghz networks in both stand-alone networks (SA). and non-standalone modes (NSA), along with a number of key power-saving features and enhanced carrier aggregation techniques.

Unlike the Snapdragon 765 and 765G (Qualcomm's new midrange mobile processors based on the same general architecture as the 865), the Snapdragon 865 does not have a 5G modem built directly into the chip. Instead, Qualcomm combines the SD 865 with its X55 5G Modem RF System .

Typically, integrating a modem into a processor results in a slightly lower total power consumption than using two separate components. Using the faster X55 5G modem in conjunction with the SD 865, Qualcomm maintains peak data speeds of up to 7.5 Gbps versus the 765G (G stands for 5G support) via an integrated Qualcomm X52 5G Modem has reached only 3.7 Gbps.

Before you deal with these fat data speeds, you will not be all that After my experience testing 5G phones and networks the currently highest 5G data rate reached about 1.5 Gbps. It will take some time to actually use 7 Gbps or even 3Gbps of wireless bandwidth.

One of the general goals of the SD 865, which goes beyond 5G performance, is better wireless performance across the board. The SD 865 not only supports Wi-Fi 6, but according to Qualcomm, the chip is also the first mobile platform to offer Bluetooth SuperBand (SWB) voice for better-sounding calls when using wireless headsets with Fast Connect 6800 ( for faster BT coupling) and aptX Adaptive and Qualcomm True Wireless Stereo Plus for reduced latency, longer battery life and overall better sounding audio.

In terms of overall performance, the SD 865 is equipped with a Cryo 585 CPU and an Adreno 650 GPU, which according to Qualcomm are up to 25 percent faster than the components on last year's chip (the Snapdragon 855 [19459004)]). The SD 865 also features Qualcomm's 5th generation AI engine, which delivers twice the performance of AI learning and machine learning, as well as 35 percent more energy efficiency compared to the SD 855, according to the company.

Qualcomm even says that the SD 865 "Desktop-quality games offer", which seems a bit nebulous, although support for devices such as 144-Hz screens and the Game Color Plus feature by Qualcomm, which enhances game details and graphics, should be a welcome addition. By the way, Qualcomm, who mentions the support of 144 Hz screens, seems to believe the current rumors that Samsung plans to give the Galaxy S11 a 144 Hz display.

Finally, When It Comes According to Qualcomm, the Spectra 480 ISP of the SD 865 works at up to 2 gigapixels per second, which is an 8K video (or full HDR 4K video) or a photo shoot up to 200 megapixels Now that cell phones like the Xiaomi Mi Mix Alpha already reach the 100 MP mark, this is definitely an advantage.

While many of these upgrades may sound promising, it is largely up to phone manufacturers to integrate all of these features into new devices. Although no OEM has yet committed to using the SD 865 in future devices, the SD 865 2020 should emerge in a variety of Android phones from companies such as Samsung, LG, OnePlus, Xiaomi and more.

All we have to do now is wait for devices to launch with the Snadragon 865, so we can find out how they behave in real retail devices. This will probably happen sometime in early spring.
