Intel's Superchilled Test Rig
Barence writes "Last week, PC Pro issued a challenge to see whose PC could render a 3D graphics benchmark in the shortest time. The competition was won by an entrant with a rather unfair advantage: Intel. The processor giant's superchilled rig is overclocked to nearly 5GHz. As PC Pro explains: 'The rig itself uses phase-change cooling: in other words it's attached to a chuffing great freezer, which I believe is the big box on the right of the photo. That yellow meter with the readout is showing the temperature of its output: yes, that's minus 40 degrees Celcius.'"
Judging from that photo, we are still in the infancy of computing. The Millenium Falcon looks like that everywhere!

-40C is also -40F ... so -40 it is
That yellow meter with the readout is showing the temperature of its output: yes, that's minus 40 degrees celcius.
Correction, it's minus 40 degrees fahrenheit.

environment cools Intel.
According to one of the comments (about AMD winning $1B+ from Intel) they can afford a fairly substantial freezer...
Phase change cooling is not really that extreme of a cooling system for benchmarking... go to Quakecon you will see quite a few people with it.
LN2 (or even better liquid He) on the other hand could be considered an unfair advantage.
it will be the happening place for gamers.
Table-ized A.I.
Negative Kelvin is actually possible...

P.S. and compiling didn't take me hours, either, since I'm on Linux
Did you know that "FTW" ("for the win") is a direct translation of "Sieg Heil"?
Insane voltage... the 980 is rated up to 1.375V. I'm happy with a i7-860 @ 3.6 GHz running on 1.2V.
Intel's made upgrading much more fun considering you can get a 30-40% CPU speed increase in about 10 minutes of research and bios tweaking. Next fall there will be 8-core/16-threads on the desktop. I am loving Intel these days.
For extra effect, they should put Debian 6.0 "Squeeze" there; also recently frozen.

"Nearly 5GHz". The whole point here that everyone seems to be missing is that they made something go more than 1000 times as fast as the original 4.77 MHz IBM PC.
Now if they could give it 640MB of memory and a 110MB floppy drive...
My other car is a 1984 Nark Avenger.
It doesn't get to -40C very frequently in most of the populated (well, more than small villages anyway) regions of canada :). -35 happens, but its far from an average, unless you live all the way north in the middle of nowhere or in the territories.
I'm aware; I've actually invested in some 2012 call options on AMD stock. Even as-is they should be worth $10 a share. If Bobcat can make them competitive in the ultraportable market (Android on ARM is going to eat Intel's lunch in the netbook-level arena; x86's crufty instruction set can't compete at that low level), and/or Bulldozer makes them competitive in the mid- to high-end desktop market, that should go up to $13-15, easy. It is a hell of a gamble, though; they're still almost a full processor node behind Intel, and that's hard to compete with.
I am more interested a a FPU (food processing unit) than a CPU - how long to render Natalie Portman in hot grits?

There is something seriously wrong with the optimizations in his windows binary...
Ran in 36 seconds on a 4 x 8224 SE AMD opteron IBM x-server running linux (8 total cores at 3.2GHz)
The posts from users running Linux on the forum are showing times that are 4-5x faster than those posting benchmarks from Windows. What's going on there?
the growth in cynicism and rebellion has not been without cause
Here is what AMD was doing last year with liquid helium, which would put the temp at about 5 degrees Kelvin (about -450 degrees Fahrenheit) and running at 7 giga-hertz
Here is an AMD news blurb

Wherever You Go, There You Are
I had a 30 minute look at the source code. It's clearly optimized for shortness, not for speed.
There are some obvious performance no-gos, see lines 44-45, using a double variable as a loop counter.
Performance depends to a good extent on the erand48 implementation and whether OpenMP knows that erand48 is MT-safe.
Clock speed has reached the ultimate physical limit, light speed.
If you take a measuring tape to a motherboard and do some math, you'll see that once we got past a few GHz there's no way a bit can go from one chip to the other within one clock cycle.
The result of that is that chips need local caches and pipelines, etc, until the complexity starts digging into the performance. And power consumption skyrockets.
