I’ve sounded this warning before but now it’s all backed up by Science.
In a post that looks like it’s a pick-up from a forum somewhere, comprehensive testing is done on both Rockchip 3188- and A31s-based Retina-class tablets [Google English].
The results are rather devastating, finally proving that neither the 3188 nor A31s platforms are capable of delivering an experience anywhere near that of a Retina-class iPad. The secret sauce of the iPad isn’t its CPU or GPU — it’s memory bandwidth of a kind no other tablet offers. “Crazy” memory bandwidth that’s two to three times that of all Chinese Retina-class tablets (actually probably four to five times). This makes even the upcoming Voyo A18 questionable until it’s been analyzed in detail.
In addition, the testing brings up something I meant to post about earlier. When Rockchip delivered its SDK 2.0 to improve Retina-class tablets, they actually downgraded the resolution from Retina-class to 1600 x 1200! This wasn’t discovered until later. In China, there are many ways to skin a cat and make a fraudulent dollar.
