POWERLOGIX ANNOUNCES WORLD'S FASTEST POWERMAC UPGRADES

AUSTIN, TEXAS --June 12, 2002 -- 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."

"We are excited to be the first manufacturer to market upgrades with speeds up to one gigaHertz," said Robert Jagitsch, President. "Adding a PowerForce G4 card to a PowerMac G4 can provide performance surpassing a new machine for a lot less money."

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 L2 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 'AGP Graphics'       350, 400, 450, 500 MHz
