Difference between the AVX instructions vxorpd and vpxor

According to the Intel Intrinsics Guide,

• vxorpd ymm, ymm, ymm: Compute the bitwise XOR of packed double-precision (64-bit) floating-point elements in a and b, and store the results in dst.


• vpxor ymm, ymm, ymm: Compute the bitwise XOR of 256 bits (representing integer data) in a and b, and store the result in dst.

What is the difference between the two? It appears to me that both instructions would do a bitwise XOR on all 256 bits of the ymm registers. Is there any performance penalty if I use vxorpd for integer data (and vice versa)?
