i740
The i740 (code name Auburn ) is the first graphics processor from Intel and appeared in 1998. It was developed by Real3D, then a subsidiary of Lockheed Martin . Its performance compared to other graphics chips from NVIDIA or 3dfx that were current at the time was satisfactory, but not dominant. However, as the development in the area of 3D acceleration progressed rapidly, the chip very soon became obsolete without leaving any major mark on the market. Production stopped in 1999. Its successor is the i752 .
The i740 is the only graphics processor from Intel so far that is intended for discrete graphics cards.
technology
The chip of the i740 was manufactured in 0.35 μm by Intel and runs with a core clock of 66 MHz. The chip has 4 or 8 MB SDRAM or SGRAM with a memory clock of 100 MHz and a 64-bit data bus. However, he can also access the system memory via AGP x2 at a speed of 520 MByte / s. The graphics chip also supports backface culling , bilinear texture filtering, MIP mapping , highlights, alpha blending, fog, color and chroma keying, and subpixel correction.
The integrated RAMDAC chip runs at a pixel clock of 190 MHz, which results in a maximum resolution of 1600 × 1200 at 75 Hz. The image is output through a single VGA connection .
