That was once true, but it seems Moore has run out of steam.

'cmon Keith, you _know_ Moore isn't about clock. His observation
was just that number of transistors per chip doubled every
18 months. I don't think anybody has any "Law" about clock.

While that was Moore's original hypothesis, the corollaries extend
to everything from clocks to processing power.

Moore's Law hasn't run out of steam. Processes keep shrinking.
Our ability to use those transistors constructively _has_.

Processes keep shrinking, but a 50% transistor shrink no longer
equates to doubling the number of transistors. Wires aren't
scaling.

Gigabyte RAM is a waste for most people until software sloth and
gluttony catch up.

I don't think that's so true anymore. 1GB is about the minimum
these days, particularly at the price. This system only has 512MB
and I can see it.

Cache is a steep curve of diminishing returns.
Double core is brute force. So is bringing much of the Northbridge
on the CPU die. But has significant efficiency [latency] benefits.

I certainly agree with the above. Nothing inherently wrong with
"brute force" though. Bringing the memory controller onto the
processor wasn't about transistors though, it was all about latency
(and admitting that memory doesn't change as fast as processors).

And enables a move to HT-SRAM if gluttony continues slothful.

How is SRAM going to help when "gluttony continues [to be]
slothful"?
