ASUS Zephyrus G14 Review: AC vs Battery Performance

CPU Performance

With that out of the way, let’s check some individual CPU benchmarks under AC power and different battery profiles and see how they perform:


Clock Scaling: AC Power vs Battery

Cinebench R20

The results are pretty self-explanatory here. On direct AC power, one of the cores constantly runs at 4.3GHz while on battery (silent), it’s capped to 1.45GHz with a couple of spikes to 4.2GHz. The performance mode on battery performs very similarly to the AC power mode.

The multi-threaded benchmark is more interesting. On AC power, the multi-core boost stays between 3.7 to 4GHz. On silent mode using battery power, it drops to 2.7GHz while performance mode pushes it slightly higher to around 3GHz.


Speedometer is another benchmark that drastically changes as you shift from AC power to battery. The reason is that upon switching to battery mode (silent), all the cores are capped to 1.45GHz. Speedometer uses 2-3 cores at a time, and on AC power, two of them simultaneously peak at 4.35GHz whereas, in battery (perf) mode, they mostly stay in the 3 to 3.5GHz range with two very brief peaks to 4.35GHz.
