Larry - Re: "Does Paul have a comment?" Compression speed is one aspect. I think Intel has added the capability - probably for only a specific range of applications - of transmitting mathematical models of 2D/3D representations - which can be very compact in their mathematical descriptions - and hence FAST in data transmission. Once received, the Pentium III then generates very quickly the screen representations by processing the mathematical models, rendering the screen images. A rather simple, but illustrative, example is the description of a circle. Two transmit a "picture" of a circle, a screenfull of pixels must be transmitted, embedded in these pixels are the pixels that delineate the circle. Each pixel may be 24 bits (3 bytes) for color. At a screen resolution of 1,024 x 768 pixels, 3 bytes/pixel, requires 2,359,296 bytes - a rather large sum. Now, a mathematical description of the circle requires simply transmitting the radius (r), pi, and 2 2pi*r plus the color of the circle - 3 bytes. The number 2 requires 1 byte, pi (3.14159) requires about 7 bytes, the radius r may require 10 bytes (floating point number) and the color 3 bytes - plus 3 bytes for the background color. Total bytes equals 25. Thus 25 bytes (mathematical model) can represent the equivalent of 2.4 million bytes of screen images - in this simple case. The time to transmit 25 bytes is MUCH shorter than the time to transmit 2.4 MILLION bytes ! This can be extended to highly complex 3D models where lighting sources and surface textures can be modeled, the descriptions transmitted, and the Pentium III renders the model. Intel's emphasis, I believe, may be in this area - mathematical descriptions and TRANSMISSION of physical models as opposed to the bit-mapped representation of the generated image. The mathematical descriptions would then be processed "on the fly" by the Pentium III after reception to generate the screen image. Paul

Larry, re: better rather than faster my interpretation is that the faster the PC, the faster the compression and decompression. This results in faster transmission, even with enhanced bandwidth. Does this sound credible to you? Why this is generally true, today's PII can easily do this much faster than the modem can send or receive the data. I doubt that the PIII will make a detectable speed difference accessing most of today's web sites. Perhaps the PIII can improve image quality however. You need more processor to encode the higher quality formats like MPEG II. Jeff
