There's lots of workstation niches that are gated by VRAM size, like very complex rendering, scientific workloads, image/video processing... It's not mega fast, but basically this can do things at a reasonable speed that you'd normally need a $20K+ computer to even try. Like, if something takes hours on an A6000 Ada or an A100, just waiting overnight on one of these is not a big deal. Cashing or failing to launch on a 4090 or 7900 XTX is.

That aside, the IGP is massively faster than any other integrated graphics you'll find. It's reasonably power efficient.
