What it measures
Apple's description of the Neural Engine's history, from the first generation in the A11 chip of the iPhone X (2017) to the 2021 generation. The figure is peak throughput, the maximum the hardware can reach.
What it does not show
A theoretical peak, not a measured speed. The article does not say what the 15.8 figure measures in detail, and it gives no benchmark for dictation.
