No, it’s actually roughly a 60% increase. If it was just a clock frequency increase, you’d be right. However, the Pi 3 uses a different and improved CPU core (Cortex-A53), which by itself improves performance by roughly 25%. In some cases (and with recompiled code), the performance improvement should be even larger.
