Daystar iMac upgrades
Daystar has expanded its iMac Flat Panel CPU upgrade line, which was first announced last month. The upgrade previously was limited to 1.35 GHz for the earlier iMac 700/800 MHz systems. The is now offering for owners of the later model 1.0 and 1.25 GHz iMac Flat Panel systems. In additional to nearly double the CPU cylces, the upgrades also double the high-performance L2 cache size from 256 KB to 512 KB. The result is a "more than 2x real-world performance" gain. Daystar is using the latest Freescale 7457 and 7447 processors. "The CPU outperforms any 745x shipped by Apple, and boasts a large 512 KB internal L2 cache. The large cache allows the iMac G4 to perform at full speed, even without an external L3 cache." The 1.35GHz upgrade (iMac 700 / 800) is $550, while the 1.92GHz upgrade (iMac 1.0 / 1.25) is $590.
