Quandt claims that Qualcomm is currently testing a Snapdragon 7 chip with codename SM7475, which has a tri-cluster design similar to the original Snapdragon 7 Gen 1.
However, if you look closer at the specs the new chip has different clock speeds. The Snapdragon 7 Gen 1 has the prime Cortex-A710 core clocked at 2.4 GHz, while the three Cortex-A710 performance cores run at 2.36 GHz, and the four Cortex-A510 efficiency cores run at 1.8 GHz. According to Quandt, the unreleased Snapdragon 7 chip would get better clocks, as the prime and performance (gold) cores run at 2.4+ GHz, while the efficiency (silver) silver cores run at 1.8 GHz.
If Qualcomm replaces the prime A710 core with a new X3 and switches to TSMC 4nm instead of Samsung 4nm and starts the chip uphill with the wind behind it, it could get performance levels close to a Snapdragon 8 Gen 1.
The new premium mid-range Snapdragon 7 Plus Gen 1 chip is expected to be announced together with the Snapdragon 8 Gen 2 on November 15.
