Details on what could be the Snapdragon 7 Gen 2 surface

The Snapdragon 7 Gen 1 has been used in only a couple of phones so far, falling well short of the popularity of the 700-series chips that preceded it. Qualcomm has a new 7-series chip in the works, the SM7475, though its position in the Snapdragon family is not quite clear.

This could be the Snapdragon 7 Gen 2 or it could be labeled 7+ Gen 1. The CPU will have a tri-cluster design with 1x Prime, 3x Gold and 4x Silver cores. Leakster Roland Quandt reports on the peak core frequencies for those clusters.

The Prime core will run at around 2.4GHz, the Gold cores will peak at roughly the same frequency and the Silver cores will go up to 1.8GHz. This sounds almost exactly the same as the 7 Gen 1 frequencies: 2.4GHz Prime, 2.36GHz Gold and 1.8GHz Silver.

Unfortunately, we don’t have details on the actual hardware yet – if this is a Gen 2 chipset, it should use the new core designs. That means Cortex-A715 for the Prime and Gold cores and the improved A510 for the Silver cores. The 7 Gen 1 uses the older Cortex-A710 for Prime and Gold and A510 for Silver.

The Cortex-A715 and reworked A510 are more efficient than their predecessors, but not much faster

Assuming these are the new cores, we can expect only a small performance bump but a solid improvement in efficiency – the A715 is 5% faster and 20% more efficient than the A710. Even the A510 core got a small redesign, not enough for a new model number but it is 5% more efficient.

This year’s Snapdragon Summit starts just over a month from now and it will bring the Snapdragon 8 Gen 2. The 7-series chip will likely be unveiled at a separate venue, but we should find out what Qualcomm has planned soon enough.
