As a gamer? None of them really, the features table is also inaccurate on several rows. "AES" and "AES-NI" are the ame thing, and so are "Intel 64" and "AMD64". So it is a bit confusing to read because the features intersect more but the names are different on each row.

As a data analyst if you're using optimized libraries (numpy, Fortran or C/C++ compiled for your machine, manually written libraries), then you may care about AVX (advanced vector extensions), AVX2, and FMA (fused multiply add) operations.
