Extropic is not a common company, but these times are not. The company is developing a radical computer chip that takes advantage of thermodynamic fluctuations to perform very efficient calculations based on probabilities. These random variations occur naturally in electronic circuits and, usually, are a headache for engineers.
The chip promoted by the Startup I could find followers at a time when technological giants are increasingly looking for computer power to build AI models that perform artificial reasoning, and in which we all care about the incredible energy demand for artificial intelligence.
Extropic shared with Wired more details about his hardware Probabilistic, as well as the results that show that they are in the process of building something that could offer an alternative to conventional silicon in many data centers. The objective of the company is to manufacture a chip that is between three and four more efficient orders than the hardware current, A feat that would significantly reduce future emissions.
A close look at Extropic technology
A document provided by Extropic includes a sign of an oscilloscope, an instrument that measures the electrical voltage over time, which shows a probabilistic bit or ‘P-bit ‘ in action. A conventional bit is fixed as one or a zero. A P-bit has a certain probability of being in one or another state, and the image of the oscilloscope shows a P-bit oscillating between 1 and 0. The crucial thing is that Extropic can control the probability that the bit is in one or another state at any time. Through interactions engineering between several of these P-Bits, it is possible to perform more complex calculations.
“At first glance, this signal in the oscilloscope may seem simple, but shows a key construction block that represents the birth of the first scalable probabilistic computer platform, mass manufacturing and energetically efficient in the world,” says Guillaume Verdon, Extropic CEO and the man behind the popular, provocative already controversial online character, Beff Jezos.
