Pentium III technology brief

Tech Review heeft een Pentium III Technology brief in elkaar gezet met wat technische info over de PIII. Hier een stukkie:

ther than the 71 new Streaming SIMD Instructions or KNI, the Pentium III is basically a Pentium II, for now. When AMD released 3DNow!, people were amazed that such a boost in Quake II performance from a few new instructions could be accomplished. But Quake II is a special case. The reason Quake II saw such an improvement from 3DNow! was because of its FPU (Floating Point) dependence. 3DNow! basically improved the way AMD CPU's handled FPU instructions, which gave Quake II a nice performance boost. The reason why this was so important to AMD was because of the fact that their CPU's have a somewhat weak FPU. Unfortunately not all software benefits so greatly from 3DNow!, but FPU intensive software does. When Intel saw this, they knew they had to do something to combat it. 3DNow! gave AMD a great marketing strategy similar to Intel's MMX campaign. Now, KNI is Intel's answer to 3DNow!. Oh, and under normal conditions AMD's K6-2 processors are significantly slower in Quake II performance than Intel processors at the same MHz.
