nice, one of these 'it could work if ... ' experiments.
worthless as long as it ain't on the market and running reliable.

Gah. So many people keep misquoting or misunderstanding this article. This is NOT a 500GHz general-purpose processor. What it IS is a high-speed special-purpose chip that at that speed can decode a 500Ghz signal, for use in things like cell phones et al. Remember, not everything with a clock is a CPU. :?

They have transistors which switch at 500 Ghz or something. That's cool but not really that cool, in a CPU you need a whole PILE of transistors to switch in sequence during each clock cycle so gates which could flip at 500 Ghz would only give you like a 50 Ghz system, even without the loads of other factors which would probably prevent you making a large IC out of those things.

Indeed. The reason why the article keeps harping on its multimedia use in TVs and cell phones - specifically the line, "movie-quality video on cell phones" - is because being able to decode a 500GHz signal implies massively increased bandwidth. We already have processors that can handle movie-quality video on a cell phone as long as it's spooled off of disc media, it's a matter of actually transmitting and receiving it wirelessly or, in the case of cable TV, via coax. Funny enough, the benefits really aren't all that great, though, since you need a hell of a lot more powerful to transmit at that kind of bandwidth, so I don't see it taking off all that much unless people want to get brain tumors from their cell phones a lot faster.

Yeah, even I noticed it wasn't a normal CPU. I don't know shit about CPUs.

What about the bandwidth thing communicating through a wire or fibre optic or something? Is this applicable to that?

Sure, they will include also a "microwave-oven" feature on each cell phone! :P

And I can get a burger from Krystal and make it warm again.

I like mine with hot sauce.

...Though really, this was just an experiment. The conditions they had to put this thing under to make it do that just plain aren't applicable to consumer electronics.

Then again, they still got over 300 at room tempurature. I think.

Only 50 GHz? Well, count me out, then! :p
