Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_74038 ( "Model" text, "Launch" text, "Model Number" text, "Code name" text, "Fab ( nm )" real, "Bus interface" text, "Memory ( MiB )" text, "Core ( MHz )" text, "Memory ( MHz )" text, "Config core 1" text, "Pixel ( GP /s)" text, "Texture ( GT /s)" text, "Bandwidth ( GB /s)" text, "Bus type 2" text, "Bus width ( bit )" real, "Processing Power GFLOPs" text, "DirectX" text, "OpenGL" text, "TDP (Watts) GPU only" text )

### Question ###
What was the model's DirectX if it has a Core of 700 700 mhz?

### Accurate SQL ###

SELECT "DirectX" FROM table_74038 WHERE "Core ( MHz )" = '700 700'
