Introducing the Qualcomm Snapdragon 865 Plus mobile platform – crossing the 3 GHz barrier
Crossing the 3 GHz frequency limit for mobile processors in Snapdragon 865 Plus, although it happens for the first time in the history of this industry, it is not new for the company providing mobile processing cores, ARM, and since the introduction of Cortex-A75 cores in 2017 The possibility of reaching frequencies beyond 3 GHz was discussed theoretically and on paper. Of course, due to the consequences related to heat loss and energy consumption, this clock speed has never been used in a real product with mass distribution, and its implementation is considered a great achievement for Qualcomm. Alex Katouzian, Senior Communications and Internal Manager of Qualcomm Company in this regard at conversation with AnandTech site about the combination of aggressive physical design of the product and improvement of production efficiency as effective factors in facilitating This is the upgrade of the speaking frequency.
The internal structure of the SD865 Plus processing cores has not changed compared to the past and still consists of a Cortex-A77 core with a 512 KB cache memory at the highest level, 3 cores similar to A77 with a 256 KB cache at the middle level and 4 A55 cores. Used with 128 KB cache at low level. The main change in this, of course, as mentioned, is the increase in the frequency of the main single core, which has increased from 2.84 GHz to 3.1 GHz with a clock increase of more than 10%.
In terms of the GPU type, no changes have been made in the graphics department and Adreno 650 is still present in this SoC; However, in this case, Qualcomm has apparently increased the graphics frequency, which leads to a 10% improvement in performance. This graphics, of course, still supports screens with a maximum refresh rate of 144 Hz, and this change will probably lead to a smoother experience in this department.
CPU and GPU frequency increase are not the only changes made in SD865 Plus, and we also face new options in the communication section; Of course, these changes have nothing to do with the X55 external 5G modem, and it is still possible to use it to connect to both mmWave and sub-6GHz technologies in both SA and NSA modes. The new point in the communication part of this chipset is the use of FastConnect 6900 is hidden, which recently last May along with FastConnect 6700 were introduced. With this update, not only the Bluetooth version supported by this chipset is upgraded from 5.1 to 5.2, but more importantly, it provides access to Wi-Fi 6E at 3.6 GHz with a 2×2 connection at 6 GHz.
Passing this case, there is no other visible difference between SD865 and its plus version did not exist and everything from Spectra 480 video signal processor and Hexagon 698 digital signal processor Up to the support of a single 200 megapixel camera and Quick Charge 4 + fast charging technology, they have remained unchanged.
Snapdragon 865 Plus will soon be used in some of the flagship phones of the market, especially in the gaming category, and currently Asus ROG Phone 3 and Lenovo Legion are mentioned as the first candidates to be presented with this platform, which is supposed to It is known that both will be released to the market soon.
