I own one, Arc isn't the best, but it's still able to compete with lower end Nvidia and AMD GPUs. They ended up having to mark them down pretty drastically though.
I actually owned an Intel Zenphone about 8 years ago. Aside from being absolutely massive, it was decent.
I think Intel got arrogant. Even today, with all the benchmarks showing Intel isn't any faster than AMD, Intel is still more expensive for PC builds.
Check Microcenter, at least in the US, the cheapest AMD bundle is 299 vs 399 for Intel.
They're lagging behind in every metric.
