I have no problem with anyone being disappointed in Intel's efforts at Mobile, I am just puzzled that you seem so certain that Logan will be this home run, when Nvidia strike me as being very prone to exaggeration, or at best, obfuscation.
But as to Logan's potency, its 192 GPU cores is half of the number that go into a discrete GeForce 630, is it not?
Now I don't know if the clockspeeds of the GPU cores in Logan will be the same as they were in the discrete GF630, or lower, but how does 16 Gen 8 EU's likely stack up against half a GF630?
