Up until now, a shroud of poser has surrounded Apple’s custom engineered A4 system-on-chip; you know it’s clocked at 1GHz, likely tied to Apple’s before acquisition of P.A. Semi and made by Samsung. Outward of which, the usually other knowledge we’ve gained has come not from the mouth of Cupertino, but from a extracting wizards over during iFixit . A A4 contains at slightest 3 layers of electronics layered on top of each alternative, yet it’s finished only similarto a iPhone processor: microprocessor in asingle pac kage as well as two mentalrecall modules in the alternative package. You also learned which a iPad RAM is essentially inside of the A4 processor package, and we’re awaiting to sense even more from those folks in a entrance days. All that pronounced, there’s still most debate on either Apple’s own silicon can stand up to Qualcomm’s heralded 1GHz Snapdragon, a chip powering Google’s Nexus Asingle between alternative things. AnandTech pitted their iPad opposite the iPhone 3GS (600MHz ARM Cortex A8) and a aforesaid Sequence Asingle (1GHz Snapdragon QSD8250), regulating a series of website loads as the primary benchmark. Altogether, a A4 valid to be around 10 to 30 percent faster, though it’s impossible to say what effect a operating system has upon things. Have the gander at that source couple for some-more — you get a feeling the competitions have only begun.
