  • This is clearly a successor to the Snapdragon 7 Gen 1, and not the Snapdragon 7+ Gen 2. This can be noticed by:

    • No large core (the 7+ Gen 2 has a Cortex-X2 core)
    • An Adreno 720 GPU (7+ Gen 2 has an Adreno 725)
    • FastConnect 6700 modem, without Wi-Fi 7 or Bluetooth 5.4
    • Triple 12-bit ISPs (instead of Triple 18-bit)
    • Slow motion capture at 1080p @ 120 FPS (instead of 1080p240)

    The ISP is the most noticeable: Even the Snapdragon 7 Gen 1 has a Triple 14-bit ISP. I’m curious why only 12-bit color depth is supported in these times of computational photography.

    That said, if this chip is marketed cheaper than the Snapdragon 7+ Gen 2, it seems like a very capable chip. It is the first and cheapest 7-series chip with Cortex-A715 cores and the TSMC 4nm process is still state of the art. The AI engine supports INT4 mixed precision (in addition to INT8 and INT16), which can provide double the performance for some models with relatively little loss in precision.

    Unfortunately, hardware decoding of AV1 video is not supported.

    What is also interesting is the Triple Frequency GNSS (L1/L5/L2) support. The only other SoC that has that (as far as I know) is the Snapdragon 8 Gen 3.
