Geekbenchmark runs it tests in bursts with short delays between them to allow for the SoC to dissipate heat. They implemented that so laptops and cellphones wouldn't overheat, or thermally throttle while running the benchmark.

I get that Geekbenchmark is extremely accessible, but it is not rigorous.

Citing a benchmark that's designed to avoid thermal issues, as proof a chip doesn't have thermal issues is just bad.

My tests do not show this, but show that putting the CPU under load alone is enough to get rather disheartening results: https://imgur.com/a/ehtleu4

He tested the i7, not sure if that is comparable.
