One technical way to check for thermal efficiency of a System-on-chip (SoC) would be to check for the thermal footprint via a thermal camera. But Qualcomm has adopted a unique way to determine the efficiency from various SoCs – the butter test!
Qualcomm has taken its Snapdragon S4 SoC with two other SoCs to see which melts the butter fast. Needless to say, Snapdragon S4 comes at the top whereas ‘Competitor B’ which looks like Samsung’s Exynos 4 Dual SoC seems to be the worse.
