“At its silicon core, the fourth-generation iPad is hardly an incremental upgrade, according to chip analysts,” Brooke Crothers reports for CNET.
“The new iPad’s A6X chip packs a brand-new graphics engine that boasts a serious step up in horsepower from the third-generation iPad’s A5X,” Crothers reports. “‘Nothing’s incremental about this.
