Sun XVR-4000: 80 million polygons per second
Sun has just unveiled some details about its new Sun XVR-4000 video accelerator. According to the plan, Sun is to cooperate with software developers, testers and certifiers. This will continue for at least two quarters, so shipments of XVR-4000 may start closer to the year-end.
According to the official press release, tests show that XVR-4000 is 9 times faster than SGI IR-3 (Infinite Reality) IR-3 (Infinite Reality) at 3D objects processing and has 4 times more texture memory (should be sceptical about the former ;).
XVR-4000 features MAJC architecture, providing processing of 80 million lit antialiased polygons per second. XVR-4000 utilizes 4 antialiasing chips for polygons, stored in the frame buffer (144 MB total). Each pixel in the frame buffer is defined by up to 16 subpixel samples, randomly situated in the 64È64 matrix. Each of the 4 AA chips uses five 5È5 filters to calculate averages with weighting coefficients using 400 subpixel samples (5È5È16).
The product supports S-Video for NTSC/PAL recording and Dynamic Video Resizing; it also supports dual-monitor configurations. Sun press release mentions that visualization subsystem, based on Sun Fire V880 server with two XVR-4000 accelerators, provides up to four 1920È1200 monitor configurations.
XVR-4000 will cost about $30000.
