Scientists Find Fundamental Maximum Limit for Processor Speeds


Silicon wafers. Quantum computing. Light-based processors. Any way you slice it, scientists say that processor speeds will absolutely max out at a certain point, regardless of how hardware or software are implemented.

Lev Levitin and Tommaso Toffoli, two researchers at Boston University, devised an equation which sets a fundamental limit for quantum computing speeds. According to their studies, a perfect quantum computer can generate 10 quadrillion more operations per second than fastest current processors. They estimate that the maximum speed will be reached in 75 years.

Pentium Prosecution

The E.U. fines Intel $1.45 billion for anti-trust violations, and for doing 3.2GHz in a 1.8GHz zone

Since 2001, the European Union's (EU) anti-trust regulators have investigated complaints that chip maker Intel engaged in anti-competitive practices. They accused Intel of of paying retailers not to sell computers with AMD chips, and for using its position as the number-one chip manufacturer to muscle around competition. Today, the EU handed down the decision in the form of a $1.4 billion fine, the largest in European history.
