In autumn 1995 choice of the industry was still not clear.
#Carmageddon 2 intro audio Patch
Classic texture formats cannot be mapped easily onto complex quadrilateral shapes and each surface must have it's own texture with coordinates tied with patch orientation. But it turned out to be blind way into real 3d graphics. In the console world 3DO was first with patch surfaces that required textures to be aligned with the patch isoparms, and Sega followed with Saturn. Patch surfaces evolved rather naturally from mature blitters of previous era, adding functions for sprite scaling, rotating and curving. For example, sphere can be formed with only four quadrilaterals, but such shapes are scarce in games. Overall quadrilateral patches were easier for CPU since setup would be done with less polygons compared to triangle based graphics. Differences go beyond polygon shape, NV handles not only four vertices per polygon, but also five additional points of surface to define real curving. The 3d is built for quadrilaterals rather than more standard triangles. NV1 recieves commands from applications into frontend FIFO and aligns offsets of hardware addresses to enable PCI burst.
Those are host interface with bus mastering, VGA and DOS audio, local memory interface, graphics and video engine, and audio engine. To perform various functions concurrently particular parts of the chip are connected via internal packet bus. All processing is indeed happening in one chip, however Ramdac of own design is external, digital audio needs additional I/O convertor and Saturn ports are serviced by one small chip as well.

VL-Bus and 32 bit local memory bus were planned options, but all cards I've seen used PCI and 64 bit data width. The engine is 350 MIPS, supporting in hardware 32 channels of 16 bit 48 kHz wavetable sound with several effects. Since NV integrates audio with graphics I will delve into this territory a bit as well. The design goal was to deliver the highest value multimedia solution on a single chip, optimized for concurrent acceleration of video game systems standards and multimedia content. While Nvidia continued announcing new accelerated titles, games like Daytona USA came out only with Direct Draw renderer NV did not excel in.
NVIDIA should finish the NV architecture by the summer of 1994, in May 1995 it was exposed to the world, in July support of Sega was announced and finally in November Diamond Edge 3D started selling, barely making it to market as first consumer texture mapper. Neither variant became high volume by a long shot.

Nvidia provided full HDL source for the ST chip, it is possible its memory capacity is limited to 2 MB.
Nvidia would take care of expensive, high end NV1 with VRAM and 170 MHz dac, while ST would promote supposedly cheap and high volume NV1 based STG2000 core with DRAM memory and 135 MHz dac. At that time leading-edge foundry capacity was scarce, but in Europe ST Micro answered positively and in November strategic alliance was formed to make and market NV products together. Nvidia wanted to be high end and looked for volume 0.5 micron manufacturing partner that could give birth to a 1 million transistor ASIC. The NV1 was the first "microprocessor" to integrate GUI acceleration, wave-table synthesis, video acceleration, 3D rendering, and a precision game port into a single chip. Ground design of first chip shaped up by the end of the year. In their early years Nvidia attracted many former Silicon Graphics employees. Malachowsky was Nvidia's vice-president of engineering, and Priem, architect of industry's first graphics processor, became CTO making most of the big decisions behind the design. Huang was the former director of coreware at LSI Logic in charge of SoC strategy, and also had experience designing microprocessors for AMD. Nvidia was established in the beginning of 1993 by Jen-Hsun Huang, Chris Malachowsky, and Curtis Priem.
