ARM: We have edge on smartphone rival Intel has been trying to crack the smartphone market for years with limited success, but is poised to introduce new, more efficient processors that analysts have recently said could take a significant chunk of ARM's business. The concerns have hit Cambridge-based ARM's share price in the last month and are partly based on technical measurements that claimed a marked improvement in the performance of Intel's hardware. It is understood, however, that ARM plans to reassure investors at its quarterly results this month that its own tests show its competing technology remains a step ahead. A lot of this data comes from companies that are heavily influenced by Intel, a source said. ARM's benchmarking shows that despite [Intel's] nanometre technology, ARM designs still have better performance and are more efficient. Intel are still a little bit behind. ARM also faces concerns that the market for high-end smartphones such as the iPhone and Samsung Galaxy S4, where it makes the biggest royalties for its designs, is slowing down. "ARM would obviously prefer it if the premium end of the market kept growing as fast as it has been but there is good growth at the lower end and they are strong there too," the source said.
