In the world of highly portable, business-oriented notebooks, Apple's PowerBook notebook is a true standout. Included in its 5.3-pound, 1-inch-high case is a PowerPC G4 chip clocked at 550 MHz, 256 MB of RAM (expandable to 1,024 MB), and a 20 GB hard disk. This notebook also boasts a 6x DVD-ROM drive, a 56K modem, a 10/100 Mbps Ethernet NIC, and a 15.2-inch, active-matrix LCD with 1,152 x 768 resolution. The system comes with both the classic Mac OS 9 and the slick new Mac OS X operating systems installed.
Product Description
Take a high-performance PowerPC G4 processor, add a wide-screen display, and enclose it all in a lightweight titanium case. Apple has just created the PowerBook G4 - and redefined portable computing. If you need the utmost power for creative design, education, or business, the PowerBook G4 is ready to provide it wherever you go. Making a notebook computer the slimmest and lightest in its category shouldn't have to mean making compromises in performance and functionality. What makes a supercomputer "super" is its ability to execute at least one billion floating-point operations per second. It's a staggering measure of speed known as a "gigaflop". In addition, the PowerPC G4 can perform four (in some cases eight) 32-bit floating-point calculations in a single cycle - two to four times faster than traditional processors. The PowerPC G4 with Velocity Engine works with the PowerPC architecture to accelerate the data-intensive processing required by next-generation video, voice and graphics applications.Among the G4 key features is a vector permute function capable of rearranging data in the registers - a priceless benefit when converting data from one format to another (often necessary with voice, video and graphics applications, which typically need to save data in a number of different formats). These vector-processing acceleration advantages give the G4 microprocessor a significant edge when it comes to fast visualization of large data sets and intensive math for real-time simulations, making the PowerPC G4 perfect for everything from digital video, graphics and 3D games to astronomy, the biosciences and predictive modeling.
