Schwerter zu Prozessoren
Die Abteilung "Optical Microscopy" des US-amerikanischen "National High
Magnetic Field Laboratory" befaßt sich auch mit Trivialem. Auf dem PPC 750 von Motorola/IBM, landläufig auch G3 genannt, befindet sich das hier abgebildete Schwert. Der Web-Page ist auch zu
entnehmen, welche Deutungsansätze es für diese Abbildung gibt. Am
mystischsten und dem Motiv sicherlich angemessen, ist der Verweis auf den
ursprünglichen Codenamen des Prozessors: Arthur. Der G3 als Gralshüter der
PowerPC-Technologie und in Konsequenz des MacOS, ...kein übler
Deutungsansatz! (md)

We spotted this medieval sword near the scribe line on a Motorola/IBM
PowerPC 750, the microprocessor that is behind the wave
of new "Pentium Killer" Macintosh G3 computers. At first we thought the
sword represented the fact that the chip is on the cutting
edge of RISC processor technology, but we now believe it to be a concealed
weapon to keep the processor competitive in the
life-threatening chip wars. Another reason for the presence of the sword
icon may be that the G3 chips were code-named "Arthur"
as in Camelot and Excalibur. In a massive international advertising
campaign, Apple boasted this processor to be three to four times
as fast as a comparable Intel microprocessor, meaning that a routine task
requiring 30 seconds G3 Mac would take at least a minute
and a half on a Pentium II 400. Regardless of whether these sensational
claims are true, the PowerPC 750 microprocessor has
most certainly breathed new life into a struggling, but very popular platform.
The PowerPC 750, built in a joint collaboration between IBM and Motorola,
is a superscalar processor featuring six independent execution units and 32 Kbyte eight-way instructional and data caches. Transistor gate size is 0.17 microns, an indicator of the
advanced manufacturing process used in the fabrication of this microprocessor. Over 6.4 million transistors are crammed onto a die that is approximately a third the size of Intel's Pentium II and III and consumes only about a fourth of the power (5 watts for the PowerPC as opposed to 20 for the Pentiums).
