Audio and Video Encoding

Audio and video encoding tasks are far not the strengths of the mobile Core Duo processor working at the nominal speeds. It was defeated by the desktop products during encoding of all types that we used in this test session. Its slow results in applications of this type are determined by slow processing of FPU and SSE instructions that are actively used for streaming operations on multimedia data.

However, once we overclock it, the situation changes dramatically. At 40% higher clock speed Core Duo processor managed to improve its performance in encoding tasks by practically the same percentage. As a result, the 3GHz Intel Core Duo processor easily outperforms Athlon 64 FX-60 and Pentium XE 965.
