Upgrade Your PowerMac Or Cube With Up To 1 GHz G4 Upgrades

T he upgrade wars have officially recommenced with an announcement today from PowerLogix. The company has introduced G4 upgrades for some PowerMac models along with G4 Cubes as well. The new upgrade cards will offer processor speeds from 750 MHz to 1 GHz, and will be powered by Motorolais "Apollo" G4 processor, a recent addition to the G4 processor line.

Upgrade manufacturers saw their heyday during the Clone era of Mac OS licensing. Coinciding with the return of Steve Jobs and the end of the Clone era, the speed with which upgrade manufacturers were able to offer faster upgrades plummeted. Manufacturers such as Sonnet, PowerLogix, and the once and future Newer Technology were maxed out at 550 MHz for more than two years. This announcement from PowerLogix likely heralds a return to competition in the upgrade market from all of the players. From PowerLogix:

PowerLogix today announced the fastest ever processor upgrade cards for PowerMac G4s. The new PowerForce G4 Series 100 and Series 133 processor upgrades will be available in speeds ranging from 750Mhz to 1GHz.

With the new PowerForce G4, PowerLogix continues to lead the market in new upgrade card designs. These are the first and only upgrade cards to use the latest and fastest technology from Motorola--the G4/7455 processor, code named "Apollo."

The Apollo has four integer execution units, one double precision FPU, and four 128-bit AltiVec execution units. It also has a 256KB on-chip L1 cache running at full processor speed. The PowerForce G4 will be available with varying amounts of L3 cache.

The PowerForce G4 processor upgrade simply replaces the stock processor card. The user removes the original processor card and installs the PowerForce G4 card in its place. It installs easily in just a few minutes by following the included instructions. Installation is about as simple as installing memory.

The PowerForce G4 Series 100 upgrade cards are compatible with the following PowerMac G4s running at 100 MHz bus:

Model_____________________Original Clock Speed

PowerMac G4 iAGP Graphicsi       350, 400, 450 MHz
PowerMac G4 iGigabit Etherneti   Single 400, Dual 450 or 500 MHz
PowerMac G4 Cube                 450, 500 MHz

The PowerForce G4 Series 133 upgrade cards are compatible with PowerMac G4s running at 133 MHz bus:
