x86 Bit Test instruction equivalent in SIMD, x86 Bit Test instruction equivalent in SIMD instructions for checking individual bits?

The Bit Test instruction BT is used to check individual bits in a register by copying the least significant bit to the carry flag such as the third one in the EAX register using.

BT EAX, 3

What I wanted to know is if there is a similar way to test MMX registers or SSE registers using some SIMD instruction? Are MMX and SSE registers the same by the way?

unfortunately, there is not. but there is PTEST instruction. it's a similar to the TEST instruction.

seems remarkable idea to me is
