The example they give is a frame rate boost on GTA V - a game released 16 years ago.

It's not the author's fault that GTA VI hasn't come out yet.

Yeah, but at 176 FPS, at first glance it seems competitive with the abilities of some fairly recent dGPUs from nvidia/AMD, though obviously we don't have benchmark-level details here.

I think this is an article allowing quiet optimism rather than all-out celebration.
