Over the weekend rumours broke suggesting Nvidia was about to dump a second slice of processing silicon onto its upcoming Ampere GeForce graphics cards to aid with ray tracing performance. This, it was suggested, was the reason behind the strange, dual-sided cooler design, and this was how Nvidia was going to change the world of real-time ray tracing in its upcoming GPU generation.

That all seemed, quite honestly, about as likely as the company co-authoring a paper with AMD about “Why you should stop playing videogames and just go play outside”. The idea of a traversal co-processor sitting on the same board as the GPU appealed to some as an elegant way of improving ray tracing performance while also making it easy to bin lower spec chips.
