Trying to get attention back from AMD, Intel says it hopes to ship a 80-core CPU by 2010. Could be exciting, if software programmers figure out how to deal with 80 threads.
A computer that runs 80x faster! Actually, no.
In introducing the soon-to-ship 4-core CPU, Intel admitted it is only 70% faster than a 2-core CPU. I should probably look it up, but it seems to me that the 2-core is 80-90% faster than single core.
Extrapolate that downward-sloping efficiency curve to 80 cores. Add in the 80x power consumption, the 80x heat generation, and the inability of desktop software to take advantage of 80 CPU-equivalents...
This turns into a very unsexy announcement.
