Graphics and crypto libraries often use CPUID and its equivalents (every
CPU I am aware of has instructions to identify its type and abilities)
in order to determine if it should use MMX/3dnow/SSE/SSE2/SSE3/SSE4,
cmpxchng, prefetch and other cache control, profile registers, etc.
None of them check /proc/cpuinfo.
