SSE

Instruksi SSE versi pertama (SSE) memperkenalkan 70 instruksi baru yang ditujukan untuk pemrosesan grafik dan suara yang lebih baik daripada yang ditawarkan oleh instruksi MMX. Selain menambahkan kemampuan kalkulasi pemrosesan MMX yang hanya dapat menangani bilangan integer, SSE juga menambahkan kemampuan kalkulasi terhadap bilangan floating-point dan menggunakan unit SSE terpisah daripada menggunakan floating-point unit yang sama seperti yang terjadi pada MMX.
