This paper intends to validate two major points: one is to demonstrate via a benchmarking study that Dual-Core Intel processing technology for mobile multimedia network systems can achieve the best performance/cost-efficiency ratio over other CPU platforms; and, as a result of the test findings, that Dual-Core-based Advanced- MC processor platforms are more advantageous than DSP (Digital Signal Processing) modules with respect to building media servers that support new subscriber services such as multimedia messaging, among others. The benchmark study consists of multimedia performance tests conducted by Kontron partner, VoiceAge Networks, whereby Dual-Core Intel CPU technology was measured against other CPU platforms in the processing of audio/video RTP streams using MPEG4, H263 and AMR-NB codecs.
