Extensions (SSE) Then Intel introduced Streaming SIMD Extensions or SSE instructions which operate on xmm registers. In 32-bit architecture, there were 8 xmm (xmm0 — xmm7) registers per logical core. In 64-bit, the number of xmm registers is increased to 16 (xmm0 — xmm15) per logical core. Each xmm
