On December 3, it was reported that Qualcomm's Snapdragon Technology Summit was on its second day, and the detailed technical parameters of Snapdragon 888 were officially announced at the event on that day.

Snapdragon 888 uses Samsung's 5nm process, which is the second SoC to be announced to use Samsung's 5nm process after Exynos 1080.

In terms of CPU, the core code is Kryo 680, with a total of 8 cores. The super core is ARM Cortex-X1 architecture, with a frequency of 2.84GHz, and is equipped with 1MB secondary cache. Its performance is 20% higher than that of A78. It is also the first mass production processor equipped with X1; In addition, there are three 2.4GHz A78 cores and four 1.8GHz A55 cores. The CPU shares 4MB three-level cache and 3MB system cache; The official said that the overall performance of the CPU was 25% higher than that of the previous generation, and the energy efficiency was also 25% higher.

The GPU is the latest Adreno 660. Officially, the graphics rendering performance is improved by 35%, the energy efficiency is improved by 20%, and it supports VRS variable coloring rate. This technology can bring 30% improvement in game performance, and the game touch response is also said to be improved by 20%; In terms of screen, it supports up to QHD+144Hz or 4K 60Hz.

The ISP is upgraded to Spectra 580, which can process 2.7 billion pixel information per second, and the processing capacity is increased by 35%. The sensor supports up to 200 million pixels; At the same time, three ISP architecture is adopted for the first time, which supports taking three 28 megapixel photos or recording three 4K HDR videos at the same time; Support taking 10 bit HEIF photos; Support 4K 120fps, 8K 30fps video recording.

Upgrade the sixth generation AI engine, and the computing power reaches 26TOPS. The main processor responsible for AI operations is the Hexagon 780 processor, whose scalar accelerator performance is 50% higher than that of the previous generation, and the tensor accelerator performance is doubled.

The previous generation 865 adopted an external baseband scheme. This time, the Snapdragon 888 is integrated with the Snapdragon X60 5G modem, which supports 5G Sub-6GHz and millimeter wave frequency bands, FDD and TDD 5G carrier aggregation, downlink peak rate 7.5Gbps, and uplink peak rate 3Gbps; The FastConnect 6900 connection system supports WiFi 6 and 6GHz WiFi 6E, and supports Bluetooth 5.2.

In other aspects, the memory supports up to 16GB LPDDR5 3200MHz and QC5 fast charging scheme of 100W level.

Overall, the theoretical performance of Snapdragon 888 has improved significantly, but the actual performance will have to wait until the end of the year to the beginning of next year for the first batch of new machines to be launched.
