Hardware, Embedded Systems The first laptops to make use of the SpursEngine, a multimedia co-processor derived from the Cell chip that powers the PlayStation 3, will go on sale in Japan in July. Toshiba will launch its Qosmio G50 and F40 machines with the chip, which contains four of the "Synergistic Processing Elements" from the Cell Broadband Engine processor. The Cell chip used in the PlayStation 3 has eight of the SPE cores plus a Power PC main processor. The SPE cores perform the heavy number-crunching that makes the console's graphics so stunning. The SpursEngine SE1000 will work in much the same way in the laptops. The operating system will run on an Intel Core 2 Duo chip and the SpursEngine will be called on to handle processor-intensive tasks, such as processing of high-definition video. This arrangement means the laptop should be capable of some tricks that haven't been seen on machines until now.

Obviously whoever wrote this summary knows very little about processors...lol. The SPEs do very little for the system's graphics, video decompression at best probably. NVidia's RSX GPU is to thank for PS3's graphics. The SPEs only do vertex math, so they may not even be useful for heavy number crunching if we're just talking ints or floats ;) The Cell and it's SPEs have proven to do a very poor job of living up to the hype they were marketed with years back. The Cell is a joke.


You obviously know very little about Cell and the SPEs yourself. And SIMD. And fast local RAM. And RAM access through the PCI/PCI-e bus. I guess googling for "Cell benchmarks" might give you some more ideas about Cell performance.
