Qualcomm's 5nm chip Snapdragon 875 structure decrypted: using Cortex X1 super core

According to foreign media reports, Qualcomm's 5nm flagship processor Snapdragon 875 will use the Cortex X1 super core for the first time. It is reported that Qualcomm Snapdragon 875 adopts a "1+3+4" eight-core design, of which "1" is the super-large core Cortex X1. In the past, Qualcomm Snapdragon flagship processors also used a three-cluster eight-core architecture of "1+3+4" such as "super-large core + large core + energy-efficient core", but the difference between the super-large core and the large core lies mainly in the CPU frequency.

Qualcomm Snapdragon chips have always been the first choice for many mobile phone manufacturers. As time goes by, the new generation of flagship chips Snapdragon 875 has gradually come into everyone's view. On September 19, foreign media reported that Qualcomm's 5nm flagship processor Snapdragon 875 will adopt an eight-core design of "1+3+4", of which "1" is the super-large core Cortex X1. This is the first time that the series uses the Cortex X1 super-large core. Previously, the super-large core used in Qualcomm Snapdragon 865 was the 2.84GHz Cortex A77, and the large core was the 2.42GHz Cortex A77.

Specifically, Qualcomm Snapdragon 875 will use a combination of Cortex X1 super core + Cortex A78 large core. The peak performance of Cortex X1 will be 23% higher than that of Cortex A78, so it is not an exaggeration to call it "super big and".

At present, the AnTuTu score of Qualcomm Snapdragon 865 has exceeded 650,000 points. It should be no problem for the Qualcomm Snapdragon 875 chip with Cortex X1 super core to break through 700,000 points.

According to the previous timeline, Qualcomm Snapdragon 875 will be unveiled at the end of this year and officially put into commercial use in the first quarter of next year. This means that next year, the Samsung Galaxy S21 series and Xiaomi 11 series will be the first flagship phones to use Snapdragon 875.
