Question: Name the series ^ when the CPU clock is 1500 and the model is t-52r
SQL: SELECT "series" FROM cpu_specs WHERE "cpu_clock_mhz" = '1500' AND "model" = 't-52r'

Question: Name the average DDR3 speed for model e-350
SQL: SELECT AVG("ddr3_speed") FROM cpu_specs WHERE "model" = 'e-350'

Question: Name the CPU clock for L2 cache of 2*512 and series ^ of e-series and DDR3 speed of 1066
SQL: SELECT "cpu_clock_mhz" FROM cpu_specs WHERE "l2_cache_kib" = '2*512' AND "series" = 'e-series' AND "ddr3_speed" = 1066
