C|Net has posted an article talking about AMD's upcoming K8 processor, which according to the article is a competitor to Intel's upcoming Merced chip (thanks Duane Pemberton). Both are expected to be discussed at next week's Microprocessor Forum in San Jose. There's not much in the way of detail, but there is this quote:

Although little is known about the K8, sources close to AMD have said that it will be a 64-bit processor, which means it can process 64 bits per clock cycle, double the current rate of current Intel and AMD microprocessors. Merced, due by mid-2000, will be Intel's first 64-bit processor. Fred Weber, vice president of engineering at AMD, is slated to speak at the conference on Tuesday.
