Depends on the density, which depends on the cell size, which to a large
degree depends on the mask size, and ultimately its bandwidth/latency. May
be that instead of using it as main memory, they stick in just enough to
store all information necessary to do instant restarting. The main problem
with "instant on" currently isn't the memory, it's the OS. ACPI 2.0 is
supposed to help a lot, but you'll still have old peripherals and old apps
that'll go screwy cos they were never written to fully allow for suspension
and power off modes. Windows is still a bit away from flawless "no power"
resumption as well.

As for MRAM, I'm not familiar with it's performance characteristics, but
it'll have to be at least up to current DRAM, with comparable room to scale up.

I've heard about this disk. What I'm concerned about is whether they'll
sell it to the highest bidder in which case it'll be hamstrung like DVD,
which suffers from the "too many CEOs, not enough engineers" scenario. The
CD was invented to facilitate Digital music. The DVD was invented to
protect company profits. And it shows. No rewritable version, discs that
only work in certain countries and so on.

PCI was the saviour of the PC, IMHO. Genuine high speed PnP even on
pre-Win95 systems. I used to debug them, lovely system. Good to see
they've been keeping it current. They've also created a High speed serial
PCI standard from what I hear, fully backward compatible. Then again,
motherboards have had what was essentially Serial PCI for a few years now.

I'm not too surprised to see a GPU that fast. Graphics cores tend to have
small and highly optimized instruction sets, as well as architectures that
can be better optimized as the type of work they do is pretty consistent in
its nature. Since large caches don't provide the same kinds of performance
gains that they do in CPUs, plus you can dump a lot of the
predictive/predicative hardware, you've got much more die space for more
hardwired functions and processing pipelines. Not to mention the very high
speed dual ported RAM they slap on.

Excellent summation, Samantha. I've been out of the game for a while, so
this is a great snapshot of the current state of affairs.
