It occurs toyself that most dual core, core 2 duo, core 2 quad and multicore core i series are probably based on something like pentium pro (with mmx) architecture. This would be fine on a two core and maybe even a four core. By the time eight cores (or more) becomes inherent, the additional instruction sets such as mmx based technology would literally provide hardware bloat in a larger multi core cpu where serial processing is inherent and required. If a 16 core cpu had 16 cores with additional instruction sets that would literally only be required on one of those cores in order to be effective, then an Intel based cpu that had eight or sixteen cores where and if each single core had additional instruction sets for multimedia (especially in consideration of modern GPUs) that this phenomen would be quite explificary as perhaps microhard, the Microsoft of hardware. Bloated system resource hogware.
