Arc is realistically a bigger threat to AMD than it is to Nvidia. The second half of the 2020's will be AMD and Intel competing over second place for desktop dGPUs.

For mobile, Arc iGPUs, while obviously not matching dedicated GPUs, can realistically offer good enough performance to some people who want to do light gaming, then stepping up to a low end dGPU just to make sure Minecraft, Fortnight, etc. can at least run may not be worth the extra cost.

Either way, I think Intel's heavy focus on putting Arc in all of their Core Ultra CPUs and heavily focusing on iGPU can be a potentially bigger disruptor than their desktop dGPUs, at least in the nearterm.
