How would SIMD do anything to address the problem's fundamental anti-cache-friendly access patterns? You'd need to restructure the problem to be cache-friendly, but SIMD won't really be relevant to that.

You can use both at once. Usually, you'd have something like 64x64 tiles in cache and use 4x4 or 8x8 tiles for SIMD.
