I am buying a laptop and I got confused regarding the GPU. What is the difference between GeForce 810M and 820M mobile GPU? Why isn't the 810M even listed on nvidia website? I looked at this link on your website and there was no 810M ( http://www.geforce.com/hardware/notebook-gpus?keys=&field_gpu_series_value=800 ) while on your driver's page it is clearly listed: http://www.geforce.com/drivers

Why is 820M so much better then 810M when they have exactly the same specifications?! ( http://gpuboss.com/gpus/GeForce-820M-vs-GeForce-810M )
Please clafiry this, thank you
