Technical Info

Image of exploded view of Silicon Graphics Octane2 The unsurpassed crossbar switch design of the Silicon Graphics® Octane2™ system provides excellent levels of interactivity with critical data transfers, such as loading a 3D model from memory to the screen. The 1.0GB per second peak main memory bandwidth and 1.6GB per second peak bandwidth between subsystems ensure that you experience smooth, fluid operations while completing even the most complex tasks. The Octane2 workstation's 8GB memory capacity gives you increased power to handle bigger data sets for more accurate analysis in less time. Configured with single or dual MIPS® processors, Octane2 delivers the power to quickly complete one task or simultaneously tackle multiple tasks such as design and analysis or motion modeling and behavior scripting. You can perform more tasks on more data than ever before at the desktop level. The exceptional system responsiveness means that you can focus completely on the problem you are solving, while working intuitively to get the job done better and faster.
