ARM Representatives have admitted that British holding company still feels at an advantage over Intel in the amounts of generated processor cores. If you take the architecture of the Cortex-A7 and 28-nanometer production technology, the processing core is ten times smaller than Atom Medfield generation , manufactured on 32nm technology. With 22-nm Intel processors, the gap will be reduced.
Even superior in speed Medfield core Cortex-A15 in size is half, as supplemented by ARM representatives . This is one of the main advantages of ARM designs , as soon as this processor with this architecture will be used not only in mobile devices, but also in servers, scalability is crucial. On one server can be placed more compact processors. The next year, ARM partners will exclusively use the 20-nm process technology, the specific performance per unit of electricity consumed once again increase.
Incidentally, ARM does not believe in the ability of Haswell processors to work in tablets.
