S3 Trio

Based on the Vision 868, the 64V+ card was able to perform YUV to RGB conversion and scaling, but its capabilities were limited to horizontal bilinear filtering (an improved version was labeled Trio64V2 and also supported vertical filtering). Later on, 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 /DX and /GX modifications, which supported more modern video memory - SDRAM and SGRAM, respectively. The budget version had an index half as small (Trio32) and had a 32-bit DRAM interface ... One of the manufacturers of cards based on the S3 Trio was "Diamond". The host controller interface of the cards of this brand was AGP-2x, the RAMDAC frequency was 230 MHz, and the chip was 100 MHz, the internal bus width was 128 bits, on board there were 4 megabytes of SGRAM operating at a frequency of 100 MHz. In 16-bit mode, it supported all resolutions up to1600x1200@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, S3 cards from prehistoric times to the present day are one of the most successful solutions for personal computers, the main task of which is to draw 2D graphics. S3 Trio was the first integrated graphics accelerator. It was in those days when "video card" and "video accelerator" were different terms, people raved about the word "Voodoo" and were proud of having 3Dfx support, driving on their simple computers to the third part of NFS.
