Ti NE5532 - real vs fake : weekend die-shot

We have spotted yet another real/fake pair of very common microchip. This time it is Ti NE5532. NE5532 is a very fine opamp which will do just fine in 99% of audio applications. I afraid it got at bit of bad fame due to fakes which have quantitatively slower slew rate and sound objectively worse.

Genuine Ti NE5532 has die size of 2103x2154µm.
