Upon receipt of the tablet, I install CPU-Z, and then, surprise, the processor is not clocked at 1.5 GHz to 1.1 Ghz but (The seller told me not to know.) Fortunately there actually has 4 cores. Be careful though, 4 cores does not necessarily mean more powerful than 2 cores. Number of dual-core processors are better than one ...
Different benchmark software confirms that he is not there a hardware detection problem. In addition, the obscure name of the processor makes me doubt it is based on the Cotex A9, but the A5.
The performance is dismal, light years of a Nexus 7 (2012), kindle fire or Ipad Mini, contrary to what is touted by the seller.
Note also hangs random wifi, there is some lag here and there.
I invite all buyers to install CPU-Z and check what they have received.
Finally the vendor has refunded us fully carefree and my wife ended up with a Nexus 7 (2013), more expensive, but at least we are not disappointed!
