CREATE TABLE table_26860595_2 (texture___gt__s_ VARCHAR2, tdp__watts__gpu_only VARCHAR2)

How many texture (gt/s) the card has if the tdp (watts) GPU only is 18?
SELECT COUNT(texture___gt__s_) FROM table_26860595_2 WHERE tdp__watts__gpu_only = "18"
SELECT COUNT("texture___gt__s_") FROM "table_26860595_2" WHERE "18" = "tdp__watts__gpu_only"
