The guy in that vid hasn't a f#ckin clue, he says SPE's in the PS3 arn't CORES, when even IBM(maker of CELL say they are).
Cell is a heterogeneous chip multiprocessor that consists of an IBM 64-bit Power Architecture™ core, augmented with eight specialized co-processors based on a novel single-instruction multiple-data (SIMD) architecture called Synergistic Processor Unit (SPU), which is for data-intensive processing, like that found in cryptography, media and scientific applications. The system is integrated by a coherent on-chip bus.
Based on the analysis of available die area, cost and power budgets, and achievable performance, the best approach to achieving the performance target was to exploit parallelism through a high number of nodes on a chip multiprocessor. To further reduce power, the team opted for a heterogeneous configuration with a novel SIMD-centered architecture. This configuration combines the flexibility of an IBM 64-bit Power Architecture™ core with the functionality and performance-optimized SPU SIMD CORES.
