Can the Cray XK6 work in real time raytracer?

I heard about the new Cray supercomputer - the XK6 - today, but I'm a little confused about where the bottlenecks are. Is it in interconnec? Can the XK6, configured, for example, with 500,000 16-core processors, get real-time graphics accuracy compatible with Toy Story 3? By "real time" I mean 60 frames per second, or about 16.7 milliseconds per frame.

No. Pure computation is surprisingly not enough for rendering a frame of a movie from Toy Story 3 or a similar modern animated (or VFX) movie. These scenes can refer to many hundreds of GB of texture, and even if you know exactly which subset of this texture will be needed for the frame, it can be tens of GB that still need to be read from disk and / or transferred over the network. GPUs or massive parallel distributed computing do not speed it up. In addition, rendering is only the last step ... preparing a geometric input for a frame (imitation of liquids, tissue and hair, tessellation of geometry, reading and interpreting large scenes from a disk) can be significant.
