SCIENTISTS have created an ultra-fast computer chip which is 20 times faster than current desktop computers. Modern PCs have a processor with two, four or sometimes 16 cores to carry out tasks. But the central processing unit (CPU) developed by the researchers effectively had 1,000 cores on a single chip. The developments could usher in a new age of high-speed computing in the next few years for home users frustrated with slow-running systems. And the new 'super computer is much greener than modern machines - using far less power - despite its high speed. Scientists used a chip called a Field Programmable Gate Array (FPGA) which like all microchips contains millions of transistors - the tiny on-off switches which are the foundation of any electronic circuit.
