CREATE TABLE table_27375 ("Core" TEXT, "Processor" TEXT, "Model" TEXT, "Clock Speed" TEXT, "L2 Cache" TEXT, "Voltage" TEXT, "TDP" TEXT, "Clock Speed to TDP ratio  ( MHz/W ) " TEXT)

how many l2 cache has a clock speed to tdp ratio of 46.7?
SELECT COUNT("L2 Cache") FROM table_27375 WHERE "Clock Speed to TDP ratio (MHz/W)" = '46.7'
SELECT COUNT("L2 Cache") FROM "table_27375" WHERE "Clock Speed to TDP ratio (MHz/W)" = '46.7'
