TSMC and GlobalFoundries Report 3GHz ARM Processors on the Way
The fastest ARM chip currently available is 2.3GHz, though the majority of high-end parts are in the neighborhood of 1.6GHz, such as what's found in Samsung's flagship Galaxy S4 handset. By bumping the clockspeed to 3GHz, ARM is sending a clear message to rivals Intel and AMD that it doesn't plan on conceding the mobile market, at least not without a fight.

In order to hit 3GHz, TSMC and GlobalFoundries will use a 20nm manufacturing process, down from the current 28nm standard. By going with the smaller process, the upcoming chips are expected to be more efficient than today's silicon, which will ultimately benefit battery life.
While this is going on, Intel will make a bid for mobile devices with its Bay Trail chips. Some benchmarks have shown Bay Trail to be around 30 percent faster than ARM's fastest chip.
