The PowerLogix PowerForce47 G4/7447 Series Cube Processor Upgrade is one of the most advanced Processor Upgrades ever for your G4 Cube PowerMac!
In 2002, PowerLogix was the first to ship G4 processor upgrades for PowerMac G4 AGP and Cube models. Later, PowerLogix was the first to ship the new 7457 processor upgrades for these same machines.
Now, in 2005, PowerLogix is the first to ship Dual 7447 and 7457 Processor Upgrades for your G4 Cube, setting a new performance benchmark.
A Perfect Complement to your Cube
The PowerForce47 Cube Upgrade provides a great performance boost while also generating less heat than 7451 and 7455 based processor upgrades.
The Coolest Running Cube Upgrade
It's all about experience. PowerLogix has more experience with more Cube Upgrades installed than any other manufacturer.
Power Management:
Additional features, such as CPU temperature monitoring and Energy Saving 'Dynamic Frequency Control' are also available for this processor upgrade via the CPU Directory software application. CPU Director is currently offered free of charge and works exclusively with PowerLogix upgrade products. Use of this software is optional and does not provide any additional speed performance benefit. Specific OS X version support is required for CPU Director and you can click here to view the current release notes and OS X versions supported.
The PowerForce G4 '47 has unique hardware features that, when combined with the new CPU Director 2.1, result in the ultimate in power management. This results in significantly lower power draw and operating temperature than any competing product.
A thermal sensor is built onto the circuit board of all PowerForce G4 '47 single and dual CPU models. This sensor is centrally located between the CPU(s) and the power supply, so as to provide a useful temperature reading. This sensor provides temperature data to CPU Director, Powerlogix's proprietary software utility.
CPU Director includes a thermal pane which appears when used with any PowerLogix CPU card that has an embedded thermal sensor. This pane shows instantaneous real time temperature, as well as a graph of temperature over time. This way the user can see the temperature change as the CPU is exercised. It can also help to diagnose problems (a fan that has failed for example.)
In addition to the reporting capabilities, CPU Director includes exclusive power management software code that allows the CPU to run as efficiently as possible.
Dynamic Frequency Switching(OS 10.3.5 to 10.4.x, not applicable to 10.5.x) :
CPU Director now also supports DFS, or Dynamic Frequency Switching. DFS allows the operating system to dynamically choose either full or half CPU speed depending on the software load. The user can set the parameters for this via the Energy Saver System Preference. Since the majority of tasks do not need full throttle CPU power at all times, when set for 'Automatic,' the operating system increases clock speed as needed, and decreases it as needed, on the fly - all without user intervention.
We have produced this Quicktime video showing how DFS works. The computer is running CPU Director, Safari, TextEdit, iTunes, and SnapzPro X is running in the background (to record the movie.) Despite running all those applications at the same time, the computer runs at half speed the majority of the time.
The video shows how Energy Saver increases the CPU speed on the fly, per the CPU demand. For example, clicking on a link on a webpage will boost CPU speed to 1.8 GHz, but once the page loads, the computer drops back down to 900 MHz.
The user can select 'Automatic' (whereby the operating system sets CPU speed); or 'Highest', which sets the CPU to full speed at all times; or 'Reduced', which sets the CPU speed to half-speed at all times.
