Today, most consumers are already familiar with the manufacturer’s pricing strategy. The most direct way is through the core hardware device of the mobile phone-the chip. To distinguish between different products of the same flagship series. In chip-related fields, Qualcomm, as the industry leader, has been influencing the entire mobile phone industry through its own technological iterations. This year, Qualcomm is even rarer to officially put two flagship chips into the market, providing mobile phone manufacturers and users with more choices. One is the Snapdragon 888 flagship that officially debuted with Xiaomi Mi 11 at the beginning of this year. The other is the Snapdragon 870 flagship chip officially released on January 19.
As we all know, the new chips that usually begin with “8” are the latest products of the Snapdragon flagship series, which means that these two chips meet the industry’s requirements for flagship products. In addition, these two chips represent Qualcomm’s mature control capabilities and exploration of new technologies in all aspects. The two chips seem to be connected during the entire transitional era. While carrying past experience, they also enlighten the future direction.
In terms of process technology, no matter which field the trend of evolution from 7nm to 5nm is overwhelming, as the Snapdragon 870 is equipped with 7nm process technology, we may not be able to say that this will be the “last climb” of the world’s advanced chips on 7nm, but the Snapdragon 870 It has indeed become the “ceiling” of 7nm process chips on the market. At the same time, the 3.2 GHz A77 main core used by the Snapdragon 870 is paired with three 42GHz A77 large cores and four 1.80GHz A55 small cores, allowing the ultra-high performance achieved by the mature technology in terms of processing speed and power consumption. The extreme achieved so that this chip still has good strength.
As Snapdragon’s first 5nm process chip, Snapdragon 888 far exceeds the 7nm process in terms of transistor density. At the same time, Snapdragon 888 uses the main core 2.84GHz Cortex-X1 in the architecture, with three 2.42GHz Cortex-A78 large cores, and four 1.8Ghz Cortex-A55 small cores. The official said that the performance is improved compared to the previous generation Snapdragon 865. 25%, with more impressive performance than similar products, it can be said that it is the king of the strongest performance in the Snapdragon chips that have been officially listed. It is worth noting that this is also the first chip to officially use the ARM Cortex-X1 design.
Its decoding bandwidth has been increased from 4 channels of Cortex-A78 to 5 channels, an increase of 25%; NEON floating-point has been increased from two 128b to Four 128b lines are equivalent to double the floating-point performance; in terms of cache, the L1 cache of Cortex-X1 is 64KB, the L2 cache is 1MB, and the L3 cache can reach up to 8MB, which is twice that of Cortex-A78. The peak performance of Cortex-X1 is 30% higher than that of Cortex-A77, and it has a 22% performance advantage over the latest Cortex-A78, and its machine learning capability is twice that of Cortex-A77 and A78. Through excellent adaptation to the characteristics of the Cortex-X1 “customizable” mobile platform, Snapdragon 888 has finally achieved a comprehensive improvement in process, cache, architecture, NPU, and ISP.
The above mentioned are the basic configuration of these two chips. It can be seen that there are obvious differences in technology between the Snapdragon 870 and the Snapdragon 888.
