1. Which systems does the Sun XVR-1200 graphics accelerator support?
2. What is the maximum number of Sun XVR-1200 graphics accelerators that can be supported in a system?
3. Am I limited to just two supported displays in a Sun Blade 2000 workstation (due to there being a maximum number of two Sun XVR-1200 graphics accelerators in a Sun Blade 2000 workstation)?
4. Who should upgrade from other frame buffers like the Sun Expert3D, Sun XVR-500, or Sun XVR-1000 graphics accelerators?
5. Does the Sun XVR-1200 graphics accelerator provide 256 MB of texture memory storage at the highest supported resolutions?
6. Will I need to modify my applications in order to use the Sun XVR-1200 graphics accelerator?

1. Which systems does the Sun XVR-1200 graphics accelerator support?

The Sun XVR-1200 graphics accelerator is a full-size, dual-slot width, 64 bit, 33 or 66 MHz PCI board that supports Sun Blade 2000 workstations. and the Sun Fire 6800 server.

2. What is the maximum number of Sun XVR-1200 graphics accelerators that can be supported in a system?

Up to 2 Sun XVR-1200 graphics accelerators are supported in the Sun Blade 2000 workstation and up to 4 Sun XVR-1200 graphics accelerators in the Sun Fire 6800 server.

3. Am I limited to just two supported displays in a Sun Blade 2000 workstation (due to there being a maximum number of two Sun XVR-1200 graphics accelerators in a Sun Blade 2000 workstation)?

No, you can support four separate displays by using the Sun XVR-1200 graphics accelerator's dual display model. The four displays can be used as independent displays or they can be synchronized to support one very large logical image.

4. Who should upgrade from other frame buffers like the Sun Expert3D, Sun XVR-500, or Sun XVR-1000 graphics accelerators?

Any user with applications requiring higher resolution, faster geometry, or texture mapping performance should upgrade. Sun Expert3D or Sun XVR-500 graphics accelerator users who require 3-D acceleration at very high resolutions (up to 2048 x 1152 @ 75 Hz or 1920 x 1200 @ 75 Hz) or stereoscopic video support (up to 1280 x 1024 @ 112 Hz) should consider upgrading.

5. Does the Sun XVR-1200 graphics accelerator provide 256 MB of texture memory storage at the highest supported resolutions?

Yes, unlike many other graphics cards where texture memory is shared with frame buffer memory, the Sun XVR-1200 graphics accelerator has 256 MB of dedicated texture memory at all resolutions. And unlike other unified memory designs, this dedicated texture memory means that texture memory requirements will not impact frame buffer memory.

6. Will I need to modify my applications in order to use the Sun XVR-1200 graphics accelerator?

No, there is no need to modify the code if your applications have been written to the standard graphics APIs: OpenGL and X-Windows. However, in order for some applications to take full advantage of all of the Sun XVR-1200 graphics accelerator's new capabilities, an application update may be required.
