Snapdragon 765G Detailed Evolution
Qualcomm officially released two new 5G flagship mobile platforms in Hawaii, the annual flagship Snapdragon 865 and the unexpected Snapdragon 765 / 765G. Among them, the Snapdragon 765, as the highest-end new platform of the 7 series, is not only the first 5G integrated SoC of Qualcomm, but also the largest upgrade since the release of the 7 series. The GPU performance has increased by 40% and the AI computing power has increased by 100%. The Redmi K30 series will become the world’s first Snapdragon 765G mobile phone and will be officially released on December 10.
The most advanced 7nm EUV process
35% lower power consumption than 8nm
The Snapdragon 765 series uses the current top 7nm EUV process, which reduces power consumption by 35% compared to the 8nm process.
EUV is an extreme ultraviolet lithography technology with a wavelength of 13.5nm. It can perform more precise lithography on the SoC silicon substrate to achieve smaller channels. Compared with the mainstream 193nm wavelength light source, the lithographic resolution is improved by about 3.3 times. Allows the processor to integrate more transistors, or a smaller chip area for the same number of transistors, while having lower power consumption and better performance.
The latest generation of integrated 5G solutions
Support SA / NSA dual mode
The Snapdragon 765G uses the most advanced 5G SoC solution at present, integrating the Snapdragon X52 modem and RF system, which is an important milestone in the global 5G commercial road.
This complete modem and RF system is designed to achieve an outstanding 5G experience through many advanced technologies including Qualcomm 5G PowerSave, Smart Transmit technology, broadband envelope tracking technology and Signal Boost.
5G modules are integrated inside the SoC. Compared with earlier discrete 5G solutions, it has higher integration, smaller size, and power consumption. 5G integrated chip solution, AP and Modem are directly connected through the system bus, the data exchange rate between them is faster and more efficient. In the traditional separated 5G solution, an additional interface is required between the AP and the modem to transmit data, and the power consumption performance is not as good as the integrated solution.
In terms of chip size, thanks to the most advanced 7nm EUV process, 765G is more precise than the traditional 7nm discrete 5G solution. At the same time as the integration level is improved, the overall chip size is smaller, truly achieving 1 + 1 <2 high efficiency integrated.
7 Series maximum time performance upgrades
GPU performance has improved by nearly 40%
In terms of performance, the Snapdragon 765 inherited the 2020 flagship Snapdragon 865 architecture on many modules, including: Adreno 620 graphics processor, as well as HVX and tensor accelerator HTA in DSP.
In terms of CPU, Kryo475 has the same architecture as Snapdragon 855. It adopts a new eight-core Kryo475 processor and a 1 + 1 + 6 three-cluster architecture. It is equipped with a 2.4GHz super large core, a 2.2GHz performance core, and six 1.8GHz efficiency cores.
The Snapdragon 765G graphics processor uses the new Adreno 620. Thanks to the same architecture as the new flagship Snapdragon 865, the Snapdragon 765G improves graphics performance by nearly 40% compared to the Snapdragon 730.
In GFXBench, the Snapdragon 765G has improved significantly in both the low-load T-Rex Tyrannosaurus scene and the high-load Manhattan 3.1 and Car Chase scenes.
The actual measurement shows that in the 3.0 off-screen test in Manhattan, the Snapdragon 765G is 38% higher than the Snapdragon 730. In Manhattan’s 3.1 off-screen test, it increased by 35%. In the Car Chase off-screen test with a larger load, the Snapdragon 765G increased by 34%.
The new level of Snapdragon Elite Gaming features helps create a high-quality mobile gaming experience, including game-specific expansions and optimization, a smoother gaming experience, and richer details and colors with true 10-bit HDR.
Same fifth-generation AIE as the Snapdragon 865
Improve AI performance by 100%
With the joint support of the new fifth-generation AIEngine and the new 5G modem and RF system, almost every mobile experience such as shooting, audio, voice, and gaming has been improved.
A multi-core heterogeneous AI computing solution consisting of Kryo 475 CPU, Adreno620 GPU, HVX and Tensor Accelerator HTA. It is worth mentioning that the Snapdragon 765G uses the same AI hardware accelerator HTA 220 as the flagship 865. The frequency is up to 700MHz. With the 1.4GHz HVX, the overall AI performance of the Snapdragon 765G is doubled compared to the fourth-generation AIE, up to 5.5 trillion operations per second (5.5 TOPS).
The Snapdragon 765G has huge improvements in CPU, GPU, AI capabilities and network connectivity. It is almost the largest upgrade of the Qualcomm 7 Series since its introduction. With the NSA / SA dual-mode 5G, the comprehensive capabilities are much higher than in the past. The Qualcomm 7 series chip can be called the “5G God U”. In daily use, the Redmi K30 5G equipped with Qualcomm 765G, whether it is a 5G high-speed experience, gaming performance, or photo effects, can get a flagship-level experience.
