The Snapdragon 8+ Gen 1, which was expected to improve performance and reduce power consumption and heat generation, actually came out with a benchmark result that it has not changed much from the previous Snapdragon 8 Gen 1.
The effect of changing the manufacturing fab to TSMC appears to be limited.

Snapdragon 8+ Gen 1 still consumes a lot of power

Notebookcheck used the OnePlus 10 Pro with Qualcomm’s Snapdragon 8+ Gen 1 to run benchmark apps like Geekbench and GFX Bench.
Then, especially in GFX Bench, where both the CPU and GPU are loaded, the power consumption was measured not much different from the previous generation Snapdragon 8 Gen 1, which had a problem with heat generation.

It is said that the surface temperature of the terminal while running the benchmark application increased to nearly 47 degrees.

Fab change to TSMC not contributing to lower power consumption?

The Snapdragon 8+ Gen 1 is an improved version of the Snapdragon 8 Gen 1, with a manufacturing fab change from Samsung to TSMC.
It was said that this would improve the problem of heat generation, which was a problem in the previous generation, but as far as the results this time are concerned, there seems to be no big change.
The high power consumption when using both the CPU and GPU means that there is no improvement, especially in game applications where power consumption and heat generation are a problem.
You may want to be careful when purchasing a smartphone with Snapdragon 8+ Gen 1 for gaming purposes.
