Higher intelligence is actually only associated with Ashkenazi Jews. Sephardim generally have IQs lower than the average European IQ. Also, high average IQ is not unique to Ashkenazis; the average IQ of northeast Asians is the same, as is the average IQ of certain areas of northwestern Europe (they all average around 115). The overall average IQ of Jews, Askhkenazi and non-Ashkenazi combined, given the large number of lower IQ Sephardim and Mizrahi, is very likely lower than the European average (which at 105 is well above the Sephardic and Mizrahi average). Given that over time, the Ashkenzi population will become increasingly mixed with non-Ashkenazis, the average intelligence of Israeli Jews in the future will be something like that of the average IQ of Yemen (about 90).
