Apple has mentioned specs but not consistently. They've said 1 Ghz processor or they will say 4 times more resolution or 9 times the graphics power of the previous models.

They certainly mention battery life and price at every unveiling.

They sometimes highlight browser benchmarks as well. The iPad SOCs have consistently been among the fastest for that year.

But they emphasize relative speed or new features, some of which would imply a certain level of performance or specs.
