How do i find my cpu id

In this table, each brand index is associate with an ASCII brand identification string that identifies the official Intel family and model number of a processor. Software can then use this index to locate the brand identification string for the processor in the brand identification table.

The first entry brand index 0 in this table is reserved, allowing for backward compatibility with processors that do not support the brand identification feature. Use brand string method instead. Table shows brand indices that have identification strings associated with them. EAX Reserved. EBX Reserved.
