Apple is making a bid to attract gaming fans to the more powerful graphics and processing power embedded in its new iPhone 7 and Apple Watch Series 2 products. The iPhone 7, which became available on Friday, features the new A10 Fusion chip — the most powerful ever in a smartphone, according to the company. The CPU fuses two high-performance cores that run twice as fast as the iPhone 6 with much more efficient use of battery power. The phone’s improved graphics performance makes it suitable for more intensive gaming.
