To show off the PlayStation 3's graphical brawn, Sony showed several game demos, including an Unreal 3 tech demo of what appeared to be Unreal Tournament 2007. In what must come as a relief to developers, Epic Games' Tim Sweeney was on hand to vouch for the PS3, saying it was "easy to program for" and that Epic had received its first PS3 hardware two months ago. He proved the tech demo was real time by showing it again and manipulating the camera and zooming in.

Interesting, perhaps not so hard to get games made after all?

No, it has one 3.2Ghz PPE (an IBM Power-based CPU) with 7 CELLs (or SPEs) attached to it.

The cells are not full processors.  They rely on the PPE to delegate specific tasks to them.  They are very limited in function, and because of time/manufacturing constraints, they can only do single precision FP work.  It remains to be seen how useful they'll be in the real world.

Again:  The one CPU in the PS3 is composed of 1 PPE and 7 SPEs.

The one processor is called the Cell. There is one PowerPC Processing Element (PPE), and eight Synergistic Processing Elements (SPE).

you're right. lol, it has some BIG performance differences when comparing single percision and double percision calculations.

#  Peak performance (single precision): > 256 GFlops

# Peak performance (double precision): >26 GFlops

    • Using Windows 10 past its end of support date, is it really that bad?

      By +Eternal Tempest · Posted

      Because of the EU (a good thing) newer android devices been getting 5 years worth of security patches. Except some Motorola which found the loop hole, and offer ZERO updates. In addition, Google for years have been making where it can patch some stuff by updating the core Google Play Store itself.  As echoed earlier,  you take the security risk in to your own hand beyond supported.

      Yes for me, I installed 'old calculator' (Windows 7 calculator) in its place since it is more useful to me. I think paint is the only one I left installed
