5 years? More like 20 years. SSE2 is supported by all 64-bit Intel/AMD CPUs released since about 2005.
SSE2 has been introduced in Pentium 4, in November 2000, then AMD has made it a standard part of x86-64, with the first Opteron launched in April 2003.
It was SSE2 which made obsolete the 8087/80387 ISA.
