? No, I was just looking at it from the user perspective. At some level, the Mac is a black box performing a function. Now, if you said you had an alternative video encoder that can change formats for me, paid or free, to go from any format to either one compatible with my iTunes/iPad or TiVo, that would have been interesting. A lecture on AltiVec, not so much. > a 1 gig intel > processor does a billion floating-point operations per second, while a > 1 gig PPC does one billion 64-bit vector operations per second. it is > theoretically 64 times faster than an intel CPU with the same clock > speed, but only if you have programmers smart enough and industrious > enough to exploit its full power. 64 times? Well, actually, I am unfamiliar enough with Intel to not speak to it. AltiVec is a 128bit SIMD, so 4 simultaneous 32 bit operands, but this is a tangent. I guess going from 2 x 1.25GHz to 4 x 2.8GHz gave me the 10X improvement, but for the wrong reason? I'm ok with that. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
