Linux: The power beneath
Re: What makes nexus 10 cpu better than a quad core?
It should. My point is that I have been doing this stuff for a very long time and I am not just spouting uninformed drivel as seems common when topics like these appear. My three, main, three-year-old linux machines each has 12 x 3.1Ghz cores/ 24 threads and 48GB of ECC RAM. But it they also support hundreds of users and many thousands of processes at any given time. And you would probably be amazed at how idle each is, even during peak loads.

If what your saying is true, then the android engineers don't know what they are doing
They mostly are. It is far easier to add more cores but much harder to make them ever faster and more efficient. And there are many, many articles our there to support the fact- When not performing massively parallel tasks (such as video encoding/transcoding or huge math models) there is a rapid diminishing return on the real-world performance from number of cores in a typical single-user machine. Throw 4 cores in a phone/tablet, do you think anyone will notice over 2 or 3? OK, now try 8? Any difference? 16? 32? 64? At the moment, the most effective spot is 2 or 3 cores. 4 is a little help. Beyond that, the overall returns are barely noticeable in these devices with typical use.
and hardware manufactures are wasting our money selling us cores that aren't used.
Most consumers have no idea what a "core" is, they just know if one model has 4 of them, then 8 of them has to be twice as good.
