G3 Performance
Compatibility
Sonnet brings the G3 revolution to previously
“upgrade-challenged” Power Macintosh® and Performa®
computers that were built with no processor upgrade
slot. Through innovative engineering, Sonnet has
designed the Crescendo™ G3/L2 to be a “plug-and-play”
processor upgrade card that installs into the L2 cache
slot of the computer. The Crescendo G3/L2
incorporates the revolutionary PowerPC™ G3 processor
and ultra, high-speed Level 2 backside cache.
