Apple typically takes the iPhone's A-series chips and updates them for iPads with more GPU cores and a faster performing, higher-clocked CPU. These chips typically have an “X” in their name, but with new iPad Pros and a fifth-generation iPad mini due in Spring 2017 the company has not yet officially announced an “X” variant of the iPhone 7's A10 Fusion chip.
Today, a source on Chinese social network Weibo posted alleged synthetic GeekBench 4 benchmark scores that could indicate at least one-fifth faster CPU performance in both single-core and dual-core computing for the purported A10X Fusion chip.
