The Intel Streaming SIMD Extension 3 (SSE3) is a set of multimedia extension instructions included in the new HT technology Intel Pentium4 produced with 90 nm techniques. Compared to previous versions, software optimized for the SSE3 realize better process performances and efficiency.
The new TMPGEnc 3.0 XPress currently in development (first release planned for Summer 2004) is optimized for the latest Intel Pentium 4 processor with HT Technology and also the previous Pentium4.
TMPGEnc 3.0 XPress uses the new memory access instructions in the latest Intel Pentium 4 processor with HT Technology and also optimize the MPEG-1/2 encoder. According to Intel, the SSE3 shows especially spectacular results in movement search routine acceleration. Moreover, software optimized for previous version of the Intel Pentium 4 processor with HT Technology will also take advantage of the new performances, providing an overall acceleration.
