Powerlogix has announced an upgrade for users of the Pismo Powerbook G3, both the beige and the Blue & White Power Mac G3, and the PCI-based Power Mac G4 (Yikes!). The upgrades feature a IBM PowerPC 750GX G3 running at 1GHz, with 1MB of cache running at full CPU speed. From Powerlogix:
PowerLogix today announced two new CPU upgrade models, continuing its leadership position in the marketplace. Both products offer the fastest clock speeds for their respective platforms.
Based on the new IBM PowerPC 750 GX CPU, these user-installed upgrades deliver clock speeds up to 1.0 GHz with a full megabyte of cache also running at 1.0 GHz. These upgrades significantly extend the useful life of these computers at a very competitive price.
The low-power IBM PowerPC 750 GX is similar to the 750 FX chip of which PowerLogix has been the sole supplier since February of 2003. However the GX has twice the L2 cache of the FX, and is available in faster clock speeds. (The FX based upgrades are are also still available.)
The first product using this chip is Blue Chip G3 Pismo running at 1.0 GHz. The Blue Chip is compatible with all Pismo PowerBooks, and is two to 2.5 times faster than the clock speed of a stock Pismo. The L2 cache is also five times faster, ensuring the highest possible performance.
The Blue Chip G3 Pismo with the 1.0 GHz 750 GX also operates very cool, due to the lower power characteristics of this chip. The CPU speed is adjustable on the fly to a lower clock speed, for additional battery life. Tests show an additional 30 minutes on a full charge can be expected (all other factors equal except clock speed.)
The second product also using the 750 GX is the PowerForce G3 ZIF running at 1.0 GHz. This model is compatible with the PowerMac G3 Beige, Blue and White, and original PCI PowerMac G4, and offers up to four times the performance of the original PowerMac.
The very economical price will be sure to please many owners of these machines who have been desiring faster CPU performance for some time.
The 1GHz PowerForce G3 ZIF and 1GHz Blue Chip G3 are available now for US$349 and US$399, respectively.
