Intel Shrinks Transistor Size By 30%

pinkUZI writes "Intel will announce that it has crammed 500 million transistors on to a single memory chip, shrinking them in size by 30%. " The tech details are sadly lacking in the article - but I'm sure those will follow. Indeed, the Yahoo piece gives the details that "...has created a fully functional 70 megabit memory chip with transistor switches measuring just 35 nanometers."

Re:Heat

[Ignignot]

It is likely that the new chip doesn't produce any more heat than the old one. It is a very simple effect: smaller transistors require less power to operate. Also, if they did consume the same amount of power in a much smaller space they'd end up as slag, no matter what cooling solution used. This means that if they were to make a current chip using the new 30% smaller technology, the result would probably produce about 30% less heat and use that much less power.

I don't really understand what the big deal is comparing the heat outputs of the P4 and Opteron is anyway, it isn't like these are mobile cpu's. I do have an Athlon 64 under the hood now, but heat output has never been a real concern of mine when selecting a cpu. I'll never understand the processor tribalism that has infected some computer users. Just use what's best for the job.

35 nanometers

With the switches this small, is it safe to say that they are using nanotechnology? I know it's not the cool molecule-sized-killer-robot style nanotech but this seems to fit the description of devices on the scale of a nanometer.

Electrons move at about 3cm/s

The speed of the electron is not the speed of the signal. Think of a cardboard tube full of ping pong balls. Stick a ball in one end, it pushes a ball out the opposite end.

10 amps of current in a 1mm copper wire has a drift velocity of about 0.024cm/s. Thats how fast the electrons in the wire are moving. The thermal velocity, however, would be somewhere around 100,000 meters/sec. Thats how fast the signal is moving. And it's really close to c/3 (a third the speed of light).

The bound electron whipping around a hydrogen atom is moving pretty damned close to the speed of light.

Sometimes, electrons can move Even faster than light!

Optical computing may or may not be the future. In theory, quantum teleportation and that kind of crap could propogate even faster than a bunch of photons.
