Afaik Weitek VGA core was licensed from Unisys "Weitek Oral History Panel " https://archive.computerhistory.org/resources/access/text/2012/10/102746380-05-01-acc.pdf https://archive.computerhistory.org/resources/access/text/20... >Roach: ... we did make some efforts to get a VGA core. We actually licensed it from Unisys, who had it internally, so they didn't mind licensing it to a merchant chip vendor, and we did that, and I think Barry deserves credit for doing the best he could to make something out of all of this, and he gave it kind of one more generation, one and a half generations, but the fundamental approach was still, coming from a high cost core, trying to go down, whereas the other guys had it much better figured out from low cost to coming up. Whole panel is depressing to read. They had two strong products, x86 copro and SUN design win copro. Rest was losing money or not selling well. As soon as SUN moved on company started having serious problems. They were convinced Weitek was in high end graphics, but every Weitek P9000/9100 benchmark I can find puts them in the middle of common PC vendor pack losing to much cheaper chips/cards. 5186/5286 vga cores performed pretty terribly (8bit video ram access when combined with P9000?), and so did the one integrated into P9100 delivering half the performance of low end Trident PCI (not liking Doom 8bit writes pattern?). Stupid marketing gimmicks, feng shui, wasting money on bad calls like speech recognition and chasing high margin products in a market racing to commoditize everything. It looks like they might have lost best people early on with Edmund Sun starting C-Cube going into video acceleration, sold for >$2 Billion in 2000, and Chi-Shin Wang 8x8 doing conferencing and still holding on with ~2000 employees and almost a $1B revenue.
