Carbon nanotube 16 bit CPU comes of age

More details in an arsTECHNICA article, worth reading:

"the clockspeed was only 10kHz"

"Overall, this is an impressive bit of engineering and an important validation that we can integrate carbon nanotubes with our existing chipmaking processes, as well as with the additional electronics that are necessary for a processor to function. But it doesn't go very far in terms of solving the issues that keep carbon nanotubes from reaching their full potential."

It can use the Nantero nanotube RAM!

Thanks. I missed that minor detail in my initial enthusiasm for it.

It is still impressive to get it to work at all - even if slowly.

Could 1024 of them operating in parallel, even slowly crunch down some serious processing?

If the problem is amenable to such parallellism, 1000 cores could net you a massive under 10MHz effective performance. For problems that aren't paral lel processable, you're stuck at 10kHz. Hopefully the next generation can o ptimise the structure somewhat - never know, it might even reach 0.1MHz

I do think the way of the future is to write code to max out its parallel c omputability, and have a whole pile of extra cost-cut cores.

Only very limited application can live with 100kHz speed. Speed is critical for optimal design
