S3 Trio

Based on the Vision 868, the 64V+ card was able to perform YUV image conversion to RGB and scaling, but its capabilities were limited to horizontal bilinear filtering (an improved version was labeled Trio64V2 and also supported vertical filtering). Subsequently, the capabilities of video adapters based on the Vision 868 were used in VIRGE/DX and VIRGE/GX cards. Being a relative of VIRGE, Trio64V2 also existed in modifications /DX and /GX, which supported more modern video memory - SDRAM and SGRAM, respectively. The budget version had half the index (Trio32) and had a 32-bit DRAM interface...One of the manufacturers of cards based on S3 Trio was Diamond. The host controller interface for cards of this brand was AGP-2x, the RAMDAC frequency was 230 MHz, the chip frequency was 100 MHz, the internal bus width was 128 bits, there were 4 megabytes of SGRAM on board, operating at a frequency of 100 MHz. In 16-bit mode it supported all resolutions up to 1600x1200@85 Hz. It was a good thing for its time, and even now in many office computers that process electronic accounting and reporting tables, these video cards successfully cope with their duties.
According to Wikipedia, from prehistoric times to the present day, S3 cards have been one of the most successful solutions for personal computers, the main task of which is drawing 2D graphics. S3 Trio was the first integrated graphics accelerator. This was in those days when “video card” and “video accelerator” were different terms, people raved about the word “Voodoo” and were proud of the presence of 3Dfx support, driving the third part of NFS on their simple computers.
