The RTX prefix is only used to denote cards which house Nvidia GPUs with dedicated ray tracing hardware, but AMD's RDNA 2 GPUs and RDNA 3 GPUs also support real-time ray tracing acceleration.
Intel's Alchemist graphics cards support ray tracing, even, though as more budget offerings you can't expect super-high frame rates while it's enabled. Otherwise Intel's ray tracing acceleration is pretty good.
