Snapdragon 720G (SM7125) – successor to Snapdragon 710 and 712
The most efficient of the presented systems is Qualcomm Snapdragon 720G. This SoC made in an 8-nanometer technological process has eight cores in the 2 + 6 system. The system consists of two Kryo 465 cores based on Cortex-A76 clocked at 2.3 GHz, which are responsible for performance, and six Kryo 260 cores based on Cortex -A55 clocked at 1.8 GHz for efficient operation.
The letter G in the processor name comes from the word "gaming" and indicates that the mid-shelf system supports all Qualcomm technologies that make life more pleasant to players, including HDR and aptX Adaptive Audio codec, as well as containing appropriate optimizations designed for games.
Adreno 618 GPU known from Snapdragon 730 will take care of gaming performance. It offers support for OpenGL ES 3.2 and Vulkan 1.1 technologies. New here are the Hexagon 692 DSP and the new Spectra 350L image processing processor.
The system has a Snapdragon X15 LTE modem, Bluetooth 5.1, Wi-Fi 6 and USB 3.1 support. SoC is able to support UFS 2.1 memory and up to 8 GB RAM. For this it supports resolutions up to 2520×1080 pixels in 90 or 120 Hz with HDR. Quiack Charge 4 support is also present.
Snapdragon 662 (SM6115), or "zapchajdziura"
The new Snapdragon 662 is a system that places performance between Snapdragon 660 and Snapdragon 665. It is the first processor in the Snapdragon 6 series that is able to store images in HEIF format, which allows you to save photos in high quality, with a size reduced by up to half.
SoC made in lithography 11 nm uses eight Kryo 260 cores based on Cortex-A73 clocked at 2 GHz, in a 4 + 4 system. Adreno 610 GPU is on board.
The medium supports resolutions up to 2220×1080 pixels in 60 Hz. It offers support for UFS 2.1 and eMMC memory. The Snapdragon X11 LTE model is integrated with the chip, and the module itself offers support for Wi-Fi 6, Bluetooth 5.1 and dual-band GPS. There is no support for Quick Charge 4 – instead there is support for the QC 3 standard.
Snapdragon 460 (SM4250-AA) – a revolution in a low price shelf?
According to the announcement, Snapdragon 460 is even twice as efficient as Snapdragon 450. Could the 4 series systems finally work satisfactorily? Snapdragon 460 uses 11 nm lithography and offers eight Kryo 240 cores clocked at 1.8 GHz and Adreno 610 GPU known for more efficient SoC. In terms of GPU, performance growth can reach up to 70%.
The processor supports resolutions up to 2280×1080 pixels and image refreshment at up to 60 Hz. It can be paired with both eMMC and UFS 2.1 memories. Snapdragon 460 is also the first processor in the 4 series, which thanks to Qualcomm FastConnect 6100 is to offer not only greater efficiency and energy efficiency, but also communication modules known from more expensive systems – Wi-Fi 6, Bluetooth 5.1 and a Snapdragon X11 LTE modem with working parameters Snapdragon 662. The chipset supports Quick Charge 3.0.
It seems that this year MediaTek will have to try hard to offer a similar set of functions to those offered in Qualcomm's production systems.
