[Beowulf] El Reg: AMD reveals potent parallel processing breakthrough

The game console business is a strange one, and I don't know that it has
much to bring to the HPC world (whoa, that will provoke some comment).
Sure, razzle dazzle graphics engines wind up in game consoles, but those
same engines wind up in other form factors. People DO build
supercomputers with special purpose processors (physics engines), but the
lack of availability of people to program them probably makes the original
Beowulf concept of "commodity PC with fast interconnect" very, very
attractive. Ultimately, you need to get useful work done, and that takes
fast hardware and people to program that hardware.
For every person skilled at programming nVidia, or Cell, or
whoosiewhatsit, you can probably hire 1000 people to grind out C code on a
(anyone looking for a job programming SPARC V8 or doing verilog on FPGA
or, even better, both at the same time, and interested in working at JPL
in sunny southern California, send me your resume instantly)

Nobody cares how much power a game console draws, as long as it's not more
than you can pull from a standard socket. Figure, for the US market, 7Amps
at 110V, or 770 W.
The TV you're displaying the game on draws several hundred watts. The
not-very-efficient sound system draws several hundred watts.
The only issue with power dissipation is keeping the internal temperatures
reasonable without needing a noisy fan. (quiet fan is ok)

I don't know about the market size.. It's growing, certainly, but people
eking out an existence at $30/month in a factory in Bangaladesh aren't
likely to be buying game consoles. I suspect that the total number of
people able to buy a console, of any brand, isn't rising all that fast.

I think it's more about software availability, etc.
A sampling of my kids' friends seems to rate Xbox/360 better than PS/3 for
a variety of reasons. Could be just marketing and not technical
superiority (not that Sony would know anything about that..)

I don't think anyone is still using their PS/1, or even the PS/2. Ours is
gathering dust on the shelf, long since supplanted by the Wii and Xbox/360.

Who cares how much power it draws.. Certainly not the user, except
insofar as more power means more expensive power supply which raises the
price of the overall box (slightly).
