Aug 2 (Reuters) - Alphabet Inc"s (GOOGL.O) Google will use processors designed in-house for its Pixel phones launching later this fall, in a shift away from Qualcomm Inc"s (QCOM.O) technology that has powered the search giant"s Android devices for more than 15 years. The processor, called Tensor, will power the Pixel 6 and Pixel 6 Pro phones, Google said in a blog post, with the company set to disclose more details closer to the release. (https://bit.ly/37fXJtO) Shares of Qualcomm, the world"s largest maker of wireless chips for smartphones, were down marginally in afternoon trading. Google said the next Pixel phone, 5a, would still have a Qualcomm processor. "We will continue to work closely with Google on existing and future products based on Snapdragon platforms," a Qualcomm spokesperson said in a statement. Last year, Apple Inc (AAPL.O) started using its own central processor designed for Macs, in a step away from chipmaker Intel Corp (INTC.O). (https://reut.rs/3lt7ZHr)
