- I think the internal speed on chip is not the issue. The DEC Alpha is
- 200Mhz on chip!
-
- I also read that the initial silicon runs of the 486 REALLY ran at 50Mhz,
- but the problem was designing a backplane and/or motherboard that wouldn't
- "make like an antennae" at those frequencies. Even though the digital
- clock rate is 50Mhz, all kinds of frequencies up into the gigahertz are
- being generated, and microwave simulations are required just to run
- traces correctly on a motherboard. Has anyone heard the same thing?
