64 cores

And yes, fewer more powerful cores favor most tasks including gaming, while slower but more cores favor video rendering and a few other tasks.

Exactly, particularly for 3D rendering that is true, as you can split up a frame into a grid and render each square in the grid separately. That ability to take a task and break it down into a number of smaller tasks, is what enables parallelization, which is where multiple cores come into play. That also explains why GPUs tend to have a lot more cores than general purpose CPUs.

For normal video playback, that is not true however, so having multiple cores for simple video playback is pretty useless.

At least on smartphones, there aren't a lot of tasks that can be split up in that way, which as you say, is why this thread doesn't make much sense.
