We all had some laughs when the two-bladed razor was
improved with the
addition of a third blade. Late-night comedians joked about
razors coming with four or even five blades.
Then, we all had a few more chuckles when the four-bladed Schick
Quattro actually made it to market, soon followed by the five-bladed
Gillette Fusion. This led to speculation about the natural
The same thing is happening inside our computers. For the
first couple of decades, they had one video card. Then two:
And of course, four, at least on the bench:
Need I say that this is getting to be ridiculous?
reports that for a two-card system with their leading product
(two 8800GTX cards), you need a lot of power:
For the NVIDIA GeForce 8800 series, the power
requirements to run in single card mode aren’t all that much different
then running any other high end card. NVIDIA recommends a 450W power
supply for GTX-based cards or a 400W power supply for GTS-based cards.
For the 8800GTX card you’ll require 2 available PCI-E power connectors,
the 8800GTS only requires 1. If you’re a hearty soul who likes to live
life to the fullest and can afford to super-size it by running dual
8800 cards, you’re going to need to find a power supply in the 850-1000
watt range. This is roughly the equivalent of running an extra
refrigerator in your house.
So a four-card system will be like running an extra
having an extra teenager in your house.
What is far more interesting, not to mention practical, is the
system they concocted at Tom’s Hardware recently.
This is a system designed to run off power from solar panels.
The cost was about $1000, for the computer itself.
(Solar panels are extra.)
If that seems like a high price, consider that a single nVidia 8800GTX
will set you back >= $550.
The power required for this thing is a stark 61 watts,
at peak. It has an AMD Athlon 64 X2 BE-2350 CPU, 2GB RAM, and
uses onboard graphics from the Gigabyte GA-MA69GM-S2H motherboard.
They are all off-the-shelf components, although the href="http://www.tomshardware.com/2007/09/13/hardware_components/page3.html">power
supply is a specialty item, since it runs on DC.
That 61 watt
power requirement includes the monitor, by the way.
The monitor accounts for 23 watts.
It runs Vista acceptably well. As a bonus, it has
HDMI and DVI with HDCP output capability.
The authors cheated a little bit: they stated by saying they wanted a
system that could play high-definition video. This system
will, but they did not include speakers. It can run 5.1
audio, but obviously you’d need speakers for that.
