"Do you have any hard numbers to confirm this?? RISC processors at the same speed as a CISC processor are typically SLOWER because they do LESS work per instruction than a CISC processor. "
This would be true if RISC and CISC today ment
what they used to me. In fact many of todays so
called RISC machines have more powerful instruction sets, with for example three operand
instructions with multiple addressing modes. Mean while the
major architectual inivations from risc processors
like pipe-lining and superscalar are on all modern
microprocessors. For more info see this ars-technica article.
All this, plus the AMD vs INTEL megahertz wars, leads to a curious roll reversal where so called
RISC chips do more work per MHz, while so called
CISC chips (actually only the x86 is called CISC
these days), have the highest clock rates.
The main problem with a computer display in
glasses is as discussed above eye strain.
Imagine an standard but small LCD display in
front of your eye. To focus on it, is the same
as focusing on any object 2 cm away from you
eye, downright impossible unless your extremely
short sighted. This is easy to fix you put a
lens in front of the LCD so that to correctly everything
is focused at infinity or maybe 20 feet away,
i.e. your
eye has to focus as if the image was at infinity or 20 feet. But this is still is not good enough.
The eye (and brain) is built to be continously
focusing on different objects at different depths,
and keeping it locked at in single focal depth for
very long produces eye strain. Worse still is that
if your viewing a 3d image, the parallex clues the brain gets to what distance an object is
at, have nothing to with what depth the eye has
to focus at, and this could cause further problems
with eye strain, that you wouldn't normally get
just by staring somewhere for a long period of time.
True when you look around a room you don't tend to
notice objects coming in and out of focus, but this is
in fact because the Brain uses the eye
to update the model of your surroundings and it
is this model you normally perceive.
Until someone can design a system that has
different virtual objects at different focal depths, eye strain will painfully prevent such
displays becoming popular consumer items.

Trek soft porn? What does that make Lexx then, German fetish porn.
Come on guys, all TV shows are mostly populated
by attractive actreses and actors, that does not make them porn, not even soft porn.
I would not even describe Lexx as soft porn, despite nearly half the shows be themed around sex. For a work of media/act to be porn its primary purpose is to aid masturbation. Where as
Trek and the other sci-fi shows primary purpose
(not always achived) is to engage the viewer with compelling plots and characters.
The Nforce Reference board was Benchmarked today

"Besides, as the name indicates, Desert Storm took place in a desert. Flat land, few landscape features. Afghanistan is a country of freaking mountains. The natives know the landscape, and we don't. A little troop of snipers can hold a valley against a company. They can hide in caves you don't know of. They can take those mountain paths you don't know of."
This isn't the 1800s, we have satellite maps, air

Java is no where NEAR the speed of C, java makes everything High level and must be run through in an interpreter in order to run (which is most of the slow down).
But if the interpreter is a highly advanced on
the fly optimisating JVM like in Hotspot, you
may well find its optimising your code to a native
binary than you C compiler does. Have you tried
Java 2, v 1.4 beta 2 yet?, a lot of Java slowness
was not due to the JVM but due to badly designed
I/O and String classes. Additions to Java 1.4
add a Native Input/Output libraries for much
faster access, and move powerful access such as
mapping a Buffer to a region of a file.
At present it only runs on Windows X86 and
Linux X86, thats doesn't sound very portable
to me.
The OpenGL support is nice, and might even
make it useable for 3D games.
The Virtual machine doesn't support JIT
compilation, so i can't see how this can ever be
better than advanced JVMs like Suns Hotspot. They claim there CISC VM is so fast it doesn't need a JIT, i find this very unlikely, benchmarks please.
Threading and SMP support was not mentioned can
IVM handle these yet?
A C/C++ compiler is not available, only Java
and Objective C (both missing libraries), i've never
tried Objective C (what are its pros and cons), so can't comment on it, but if your programming
in Java you might as well use the Java virtual
machine instead of this one.
All in an interesting project, that might become
a useful programming tool, but not for another
couple of years.

Also, Aircraft security, the pilots cabin should
be sealed with a code lock, the pilot should have

Possibly AMD are under marketing here, a Palomino
athlon @1400 is by most benchmarks (except quake),
about as fast as an P4 @2 GHz, see the HardOCP review.
So AMD aren't really
extending there numbers has far as they could.
I guess AMD are trying to keep the Athlon brand
image by still winning the all benchmarks.
An Athlon-4 1600 will still comfortably beat
the P4-1600 at almost all benchmarks except
quake 3 (Athlon might just win at quake 3 too given an Nforce MB) and SPEC.
Like Tom says AMD have to do this because they
just can't sell to Joe Sixpack based on true
performance only on the single performance rating.
AMD just announced that its revenues will
be down 15% this quarter, which translates to a
big loss. OEMs seem to force Athlon prices to be
slightly lower than a P4, clock for clock. Now
with Intel selling P4s from 1.3 to 1.5 at $133, AMD just can't get much over a 100 bucks for its top CPU, and at those price they just can't make any money.
If AMD do somelike.
Athlon 4 @ 1400GHz = Model 1600
Athlon 4 @ 1533GHz = Model 1750
Athlon 4 @ 1600GHz = Model 1850
Athlon 4 @ 1733GHz = Model 2000
Then assuming they can actually make these chips,
and get OEMs to buy them near P4 prices (Model
number for P4 MHz), they'll be able to make some money next quarter.
Companies "up north" will still recoverer R&D for
sales in rich countries, in North America and
Europe. Brazil couldn't afford the drugs anyway
so Roche have lost much money at all.
Actually the most popular (with physicists)
explantation of the "Quantum Mystery", is the
Everett Wheeler aka Many Worlds Interpretation.
Thanks to the sciences of Decoherence and
Quantum Computation, Many Worlds is pretty much
the only solution. Without the other universes, whats doing the computation in a quantum computer.
They are still some Slot A, Thunderbird 1GHz
Athlons, which would be your simplest ungrade.
But with anything so cheap right now, why not
get a new MB and an Athlon 1.4GHz, Or maybe
wait for a 1.5GHz Palamino on the nForce 420
MB (which should rock).
AMD are committed socket
A well into 2003 (with "Barton" Athlons on a.13
micron copper SOI process), so a new MB shouldn't
be to much of a dead end.
No AMDs license for the Alpha bus can't be
revoked.
An analyst asked the same question at the
AMD earning conference call and Jerry
Sanders gave a firm reply that the Bus license
is solid. BTW the CC is worth a listen just to
here Jerry slagging of the P4:
"
A: I think the
the P4 is a dud. The P4 is a lousy product and they have to price it cheap and
made a lot of noise that they wouldn't give up any market share in a marketplace that wants lower cost solutions.
AMD is in a very good position with the Duron to do that, with the Athlon to do that.
Pentium 4 is a loser. Intel is spending
tremendous amuont of money in 130nm
so that they can be marginally competitive.
