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)" " =E2=80=98btver1=E2=80=99 CPUs based on AMD Family 14h cores with x86-64 i= nstruction set support." " btver1 is a SSSE3/SSE4a only CPU - it doesn't have AVX and doesn't support XSAVE."
