The First Carbon Nanotube Computer
A carbon nanotube computer processor is comparable to a chip from the early 1970s, and may be the first step beyond silicon electronics.

WHY IT MATTERS
For progress in computer power to continue, new materials will be needed for the most basic components.
For the first time, researchers have built a computer whose central processor is based entirely on carbon nanotubes, a form of carbon with remarkable material and electronic properties. The computer is slow and simple, but its creators, a group of Stanford University engineers, say it shows that carbon nanotube electronics are a viable potential replacement for silicon when it reaches its limits in ever-smaller electronic circuits.
The carbon nanotube processor is comparable in capabilities to the Intel 4004, that company’s first microprocessor, which was released in 1971, says Subhasish Mitra, an electrical engineer at Stanford and one of the project’s co-leaders. The computer, described today in the journal Nature, runs a simple software instruction set called MIPS. It can switch between multiple tasks (counting and sorting numbers) and keep track of them, and it can fetch data from and send it back to an external memory.

Как всегда в таких статьях, в комменты прибежал болельщик за ARM и начал агитировать за любимую архитектуру, не понимая, что 1) ARM и MIPS - обе RISC-архитектуры, возникшие примерно в одно и то же время; 2) 4004 не имеет никакого отношения к MIPS; 3) представлять эволюцию компьютерных архитектур как "4004 -> 8088 -> ARM" - это

How long until an 8088? That will bring us from the 70s to the 80s.
However, going after an ARM type of design might bypass all of that.

@sanman You are obviously got confused by the reference to 4004. 4004 is used in this article to compare 1) the relative complexity of the chip 2) the fact it is first of its kind.
This nanotube chip is using a subset of MIPS architecture, not 4004 architecture. MIPS architecture has nothing to do with 4004. In fact MIPS and ARM are siblings - both are RISC architectures that emerged at the same time - early 1980s.
Both MIPS and ARM are used in modern gadgets like digital TVs, routers etc. ARM is more popular because of its use use in cell phones. But MIPS has certain advantages over ARM (hardware multithreading in some cores, better handling of 32->64 bit compatibility) and MIPS proAptive core beats ARM Cortex A15 on benchmarks.
