The next Weiteks? |
|
|
With so much heat generating in the gaming segment this holiday
season(like in
the past few years), it seems that GPUs are becoming standard bundles
in
desktops.
So, are we likely to move to a co-processor approach with GPUs and are
NVIDIA and ATI the new Weiteks in the industry? |

Seems like heat is at least in the top 3 problems for what's keeping
CPUs below 4GHz. I remember people, back in the day, getting 800MHz
AMD CPUs going up to 2GHz, with liquid nitrogen.
So massively cooling can give massive performance gains, tho obviously
something a bit more practical than liquid N2.

The wiring in my apartment is a bit dodgey. If I ran a high power
system the water cooling would be from the local fire department.

Most of the heat from my 1.3 Ghz P3 system is from the power supply.
In fact the processor has a passive heat sink and is only 5 to 10 degrees
F above room temp. And I haven't heard of them water cooling power
supplies yet.

tasks (or threads) going at once, so it's only a small tweak to one's
source code. But where are we going to be in years to come? How are
the NSA going to spy on us, for god's sake?

It's probably more than a small tweak. The big problem is somebody
actually has to go out and multi-thread or parallelize the software.
It's not going to happen by itself.

The power supply efficiency is just a matter of cost. Power supplies could
have efficiencies of 98% for the primary part (transforming AC to buffered
400V DC), and at least 96% for the 12V rail. The main problem: You need low
drop switches for that (expensive ;-), and especially air-core coils (no
ferromagnetic core allowed). With the high voltages in the primary system
(until you get to 12V), you don't need that big coils (2.5A for 240V, 5A
for 110V), but the secondary system at 12V needs quite big coils (20A).

They do. One of my coworkers bought one for a system to be used in
a sound studio. |
