you mean a gpgpu processing it can beat a CPU at parallel processing application? astounding! Especially when said program is made specifically for the PS3 and Cell. You talk about me using only one example yet you turn around an use an even worse one, good job. Dont forget that the folding@home client on the ps3 according to sony is supposed to be 10x faster than a desktop CPU. How did that turn out?
The ps3 can outperform a traditional CPU when it is doing parralell processing type of applications that graphics cards and other GPGPU chips excell at, See nvidia's CUDA. But when you are using that type of stuff you shouldnt be comparing the cell to a CPu but instead the GPU.

he said his phenom can run circles and i asked him at what, what a coincidence that he didnt provide a single example, lucky for him i did, you know - microsoft officedoing parallel processing types of applications? you mean like the type of applications "super processors" are used for?
did sony say 10x any desktop cpu or did they get that 10x by comparing it to a specific high level processor at the time? you know, like a p4?
Ok, here is how it works in laymens terms: you throw raw mathematical operations at the cell and it will excel thats what it was made to do: spit out its operations. each group ofSPUs needs to be told exactly what it needs to do at any given time by its PPE.
Now a conventional program and CPUs work off of instruction sets, and each core can use different instructions at the same time and because of the instructions each core does not need to be told what it needs to do to the extent the cell does.
So basically anything that is raw number crunching the Cell will do well like as you showed earlier with the video encoding which is just abunch of number crunching.
The cell needs a program written specifically for it for it to take advantage of its power and doesnt have nearly the flexabliity as a normal CPU.
yeah, thats kind of how cell was designedas little abstraction as possible to get in the way of raw performance
you and i both know what youre talking about when it comes cell's raw performance with it comes to programs with as little abstraction as possible that utilize the spus, thats us though, im still waiting to hear what he has to say about what his phenom runs circles around cell at
