So far, the Snapdragon 7 Gen 1 has only been used in a few phones, falling far short of the popularity of the 700-series chips. The SM7475 is Qualcomm’s new 7-series chip, but its place in the Snapdragon family is still unclear.
It could be the Snapdragon 7 Gen 2 or the Snapdragon 7+ Gen 1. It will have a tri-cluster design with 1x Prime, 3x Gold, and 4x Silver cores. According to Roland Quandt, these clusters’ peak core frequencies have been revealed.
It is expected that the Prime core will run at around 2.4GHz, the Gold cores will peak around the same frequency, and the Silver cores will run at around 1.8GHz. This sounds very similar to the 7 Gen 1: 2.4GHz Prime, 2.36GHz Gold, and 1.8GHz Silver.
The hardware details aren’t available yet – if it’s a Gen 2 chipset, it should use the new core designs. For Prime and Gold cores, the Cortex-A715 is used, and for Silver cores, the improved Cortex-A510. In the 7 Gen 1, Prime and Gold use the Cortex-A710 and Silver uses the Cortex-A510.
This means we can expect only a small performance bump but a substantial improvement in efficiency – the A715 is 5% faster and 20% more efficient than the A710. There was also a small redesign to the core of the A510, not enough for a new model number, but it is 5% more efficient.
We will see the Snapdragon 8 Gen 2 at this year’s Snapdragon Summit in just over a month. Qualcomm is likely to unveil its 7-series chip at a separate event, but we should know more soon.
