Hi, Intel just showed up 100 MHz version about 80486 in some conference at California. Does anyone have a little bit more information about that processor, when it might be finally 'released' aso... -- --------------------------------------------------------------- Matti Joutkoski, mattij@yj.data.nokia.fi, tel. + 358-0-5673866. ---------------------------------------------------------------

Intel has said several times that they do not intend to release the 100mhz version of the 486. The confrence (ISSACS?) is intended to show off 'mostly working' technologies that may/maynot be actualy released. It was important for Intel to show this technology since it demonstrates that the CISC design can keep up with the RISC designes. It is interesting to note that the 100mhz 486 is 1/4 the size of the 33 mhz part-- which IMPLIES that chips will soon be holding 4 million transistors. - David K -- David Kessner - david@kessner.denver.co.us | do { 1135 Fairfax, Denver CO 80220 (303) 377-1801 (p.m.) | . . .

They announced that they will release a 50 MHz version later this year, based on technology developed as a result of the 100 MHz excercise, and that future chips would make similar use of the technologies.

The conference was the International Solid State Circuits Conference (ISSCC); I saw the tail end of the paper. The part barely made it to 100MHz under ideal conditions. In practice, that would translate to 60MHz or so in a live system, with extensive cherry picking (sorting parts for best performance) and careful control of temperature and power supply. Those parts would have to be mounted in a multi-chip module with the second stage cache memory to go at that speed. I imagine such a unit won't appear for at least a year, and be damnably expensive. Right after the paper, the author went off to a press conference, rather than to the author interviews. The session chairman said Intel may not get a chance to give any papers next year with bad behavior like that. There is an interesting three-way battle going on right now, with Microsoft forming alliances with MIPS, and Sun licensing the Sparc to other companies. Intel fights back with a fast CISC. Whoever wins, it oughta mean some fast, cheap computing iron in the next few years. -- Keith Lofstrom keithl@loop.uucp ...!sun!nosun!loop!keithl (503)628-3645 KLIC --- Keith Lofstrom Integrated Circuits --- "Your Ideas in Silicon" Design Contracting in Bipolar and CMOS - Analog, Digital, and Power ICs

A sideline to the i486/100MHz topic is the VELOX ICECap.
They have pushed an Everex 25MHz 486 to 50MHz using a Peltier
effect device (piezo electric cooling) to cool the chip to
0 degrees Celcius.
_Rumor_ has it that when the 50MHz 486 arrives the ICECap could
push it close to 100MHz.
