What I am posting is from a M$ e-mail from their own comparitive analysis
I don't think it's from Microsoft, maybe some anonymous troll sending out fake Spam. Sure Microsoft likes to mislead, but that "email" is far over the top. I won't do a complete runthrough as I already addressed everything here on VGchartz before.
Just one for illustration:
The Cell's seven DSPs (what Sony calls SPEs) have no cache, no direct access to memory, no branch predictor, and a different instruction set from the PS3's main CPU.
Each SPE does have a tiny amount of cache, they all do have DMA units and a branch predictor is not needed with properly designed SPE code (the programmer does so manually, like shifting gears, but more efficienty than a predictor can).
Why do processors need cache to perform properly? The answer is simply, operating speed, for working on data as fast as possible. One thing you will note when looking at each SPE's memory is that it's the same kind of RAM that is used for cache elsewhere. Just because this memory does share the limitations of cache when used, does not give other CPUs an advantage.
his info certainly doesnt lie and is accurate
You wish... It's inaccurate, incomplete, biased and thus entirely useless.
