With the introduction of the AMD Athlon™ processor, AMD has taken 3DNow!™ technology to the next level of performance and functionality. The AMD Athlon processor features an enhanced version of 3DNow! that adds 24 instructions to the existing 21 original 3DNow! instructions. These 24 additional instructions include:

• 12 instructions that improve multimedia-enhanced integer math calculations used in such applications as speech recognition and video processing
• 7 instructions that accelerate data movement for more detailed graphics and new functionality for Internet browser plug-ins and other streaming applications, enabling a richer Internet experience
• 5 DSP instructions that enhance the performance of communications applications, including soft modems, soft ADSL, MP3, and Dolby Digital surround sound processing. This DSP functionality is unique to the AMD Athlon processor and not supported by Intel's Pentium® III processor.
