I hope they found the magic button and pushed it but i am skeptical. If they fixed the specter meltdown things with hardware, that alone is 20-30% boost on some read and write SSD speed. If they upped the fairly slow rated memory speed Intel CPU´es have to something like 4000, that could be another 5% speed boost, but people already use faster mem then rated, so no real world boost. Together with the 1GHz lower clocks, the 18-40% IPC boost could fade away to no real world performance boost. One could hope that the lower clocks at least gave a lower power usage.
