RE: " as btver1 and sandybridge are the same arch (amd64) just different
cpus "

I'm confused here:
" *Sandy Bridge* is the codename for the microarchitecture used in the
"second generation" of the Intel Core processors (Core i7, i5, i3) "

" AMD Bobcat CPU (btver1)"
" ‘btver1’ CPUs based on AMD Family 14h cores with x86-64 instruction set
support."
" btver1 is a SSSE3/SSE4a only CPU - it doesn't have AVX and doesn't
support XSAVE."
