The PGX32 is Sun's rebranding of the TechSource Raptor GFX graphics card, and the OpenFirmware logo for it still says 'Raptor GFX', even on Sun-branded cards. It is a 32-bit, 33MHz PCI card, based on a 3DLabs Permedia2 chipset, with 8MB of SGRAM. It supports 8+24-bit overlay visuals, double-buffered, at up to 1280x1024, or single-buffered 24-bit modes at 1600x1200. The PGX32 is generally regarded as better card than the marginally newer PGX64, though it's still outclassed by the XVR-100. The Permedia2 chip does support rather weak hardware-accelerated 3D, but Sun's OpenGL doesn't support it for that, probably for much the same reason as with the XVR-100. Its 2D performance is rather good, however.
This was a very common card in Sun Enterprise 250 servers, but was also available in Ultra 5, 10, 30, 60 and 80 workstations, and in the Sun Blade 100. It works in any PCI-equipped SPARC system using Solaris 2.5.1 or later, however. A common use of the PGX32 is to provide a second head on Ultra workstations. Used PGX32s can be had very inexpensively nowadays, and even new, they were never especially expensive.
