AMD, IBM Announce Transistor Advances 125
Jugalator writes: "AMD announces it has built a CMOS transistor with the highest switching speed in the semiconductor history. The transistors are manufactured with .015 micron technology and allows a twenty-fold increase in transistors per chip with a ten-fold increase in performance when compared to the transistors in use today. So far, AMD has only produced a prototype and a larger scale production is not planned for until 2009 at earliest. AMD will announce further information regarding their research in the semiconductor field at the 2001 International Electron Devices Meeting today, December 4." schongo sent in a note about IBM's double-gate transistor.

I understand that it is probably tongue-in-cheek, but still, you are paying the electric bill for that heat, and that cost is significant if the heat is enough to warm your room.

Conduction through air is pretty lousy. That CPU can get pretty hot, and heat up the air nearby without heating up the air near you very much at all (the temperature gradient is steep). You need good *convection* to stir that hot air around to warm up the room as a whole, or *radiation* to pass through the air and warm the objects in the room.

My computer is right next to me on the desk. The 7200 RPM fan is enough to stir up quite a bit of heat around me. Over a few hours of being in my room with the door shut the temperature rises significantly throughout the room.
I don't use the computer just to heat the room, it's just a side effect.

The material will be heated by the light, so it will generate heats..
Light doesn't interact with light directly, so a light-based chip would be really a light - non-linear material - light chip.
Usually the interesting effect in those materials used to modulate light are only a "second order" effect, which means that you have to use quite intense lights to have something usefull.
Intense light --> heat.

The heat output negates the size advantage (Score:4, Insightful)
It is pretty obvious that AMD has some big heat issues. After all, Tom's Hardware was able to cook an AMD CPU and motherboard all at once just by removing the heatsink from the chip. Heat is a serious concern with these things.
However, I am optimistic that AMD can solve whatever problems there are with this technology and bring it to the consumer eventually. Hopefully that will happen before Intel uses their size and budget to crush AMD permanently.

Re:The heat output negates the size advantage (Score:1)
The way transistors work just happens to waste a bit of energy when conducting (and not conducting, too). New technologies, including feature size shrinkage and SOI WILL help the power dissipation issue. at this feature size they _could_ put fewer transistors per square mm and get less power density and still more transistors than today to decrease the heat output. But this won't happen since people want max performance. They will always go for max performance in their heat and power budget (which is governed by air cooling right now).
Now, reducing the power, or Vdd, will also reduce power density, but this requires tighter control over threshold voltage and thus the oxide interface and possibly thinner gate oxide. New technologies will answer these problems too.
This all takes a long time. for now just go buy one of those sun systems which runs at 50W!

And if you had a clue, you would know that the manual for an AMD Athlon chips states that, without a heatsink, the chip will fry in eight seconds. The same would happen with an Intel CPU, or a G4. Running any chip outside it's environment (say, without a heatsink), will not be good for it. This isn't due to any inherent 'heat problem'. With a heatsink, an Athlon runs at about 50K below a P3.

Well, 2009 is in 8 years, or 4 doublings if you're going by the 24 month rule. Top of the line chips now are minted at 130 nanometers. Double once, and you get 65, double again and you get 32.5, and double the final time and you get 16 nanometers... and the AMD transistor is 15. Going by the 18 month rule and you get a bit more then 5 doublings.
In other words, while its great that they haven't hit the wall yet, this is really all they're telling us. CPU speed has been improving predictably for decades and this is no exception.

Uh, I don't see why this is considered revolutionary. More's law states that chip density doubles every 18-24 months.
First, it's Moore's Law. Second, calling it a law is ridiculous, because it's entirely dependent on continuing R&D, as well as bringing such R&D into production. Taking it for granted that you'll have your 40GHz CPU in 9 years is really quite naive.
Personally, I can't wait until Moore's Law fails (either by falling short from or totally surpassing the prediction), so that people stop using it to degrade the really quite amazing research and amount of work that goes on in order to bring such results.
Thanks,

First, Moore's Law refers to the doubling of the density, not the speed of the chip. So your "40GHz" example doesn't fly.
I understand that Moore's law as he stated it applies to the number of semiconductors on a chip, but also that the general geek public accepts Moore's Law to apply to the speed of a processor, which remarkably seems to also match the 18-24 month rule.
Second, it is commonly referred to as a law, it wasn't the original poster's idea.
I haven't blamed the original poster for coining the term, but I can see how it appears so since I said it after the slightly anal spelling correction.
Third, once we get past silicon for chips, I think Moore's Law is out the window.
I agree, and getting away from silicon is just one variable that can make the whole idea useless. Others include quantum computing devices coming into play, 3D chip design, and clockless chips (referring to the speed-doubling correlary to this "law").

Ahhh... how soon they forget.
The first real wave of RISC CPUs did shatter Moore's law. Performance jumped from 4 MIPS to 12 MIPS. Prices dropped from $70,000 to $10,000. It was truly cool.
Of corse in the following years CISC have mostly died (seen any new ones launched? I have seen a lot die), except the x86, and to a lesser extent the 370/390/whatever-z-or-x-name-they-have-now, and the x86 has even caught up to the RISCs, and is almost all cases passed them (it's amazing what you can do with 10x the R&D budget...).
I think there have been a few places where there was underperform, like from the 386 to the 486 maybe, or from the 486 to the P1 (and I think that was due to the length of time between the 486 and the P1), but I forget exactly when mostly because nobody kept pointing it out like Sun did with "RISC is better, eat our dust DEC".
If you look at the SRAM market you will find similar events.
Still as a long term thing Moore's "Law" is amazingly accurate. I think because it functions as a goal for R&D managers. If they can't keep up with the "Law" they tell their bosses that they need more money or the company will die, if they have managed to keep up with it they don't fight as hard for the budget (or they do, but they have less ammo to fight with). I know R&D budget isn't everything, but it is a powerful force.

That IS pretty cool, but what I consider to be the "shattering" of a given law is when the majority no longer considers it valid, and that's unfortunately not the case.
I blame the marketing department, which creates the consumer demand by telling us that buying a 2GHz Pentium IV will make the internet faster.
No offense to Mr. Moore, who probably never anticipated his comment to be taken so seriously or adhered to, but it'd be nice if the focus was taken away from how many clocks per second or transistors there are, but what is done with each tick (or per recent news whether the ticks are necessary at all), and whether each transistor is used efficiently (FPGA's, anyone?). I hope to see a market where results from open, approved benchmarking methods based on real criteria are the main selling point. Guess I shouldn't hold my breath, eh? :o)

ALSO, consider that the photolithography tools that are supposed to support the next generation of smaller structures are already off-track. 157nm lithography tools have been delayed due to development and financial difficulties. See SiliconStrategies.com [siliconstrategies.com]). My personal guess is that the vertical MOSFETs will be the winners in the short term because, until they get other factors in line, they will have to make do with what they've got, though *again* the additional processing required for the wafer will impact yields, so it will be an expensive technology to implement either way.

Today's technology pretty much meets todays needs. 99% of the market would actually be just fine with a 500 Mhz P3 or Athlon system, with 20 Gig HD and 128 Meg of ram. Launch a 100GHz CPU and people wouldn't have the need, though if it cost marginally more than the current crop, of course they'd buy it, but only gamers (no, not in FPS, but in behind the scenes complexity) and engineers would see benefit.
