<i>the problem is that all of them are kinda crap, and most importantly don&#x27;t have a well established ecosystem</i><p>I&#x27;d say performance was the more important factor, as most of the early non-Intel x86 were physically compatible (drop-in replacements) - and many were actually faster than Intel&#x27;s CPUs, but Intel (and to some extent AMD) quickly caught up and passed them. The P6 (Pentium Pro&#x2F;II&#x2F;III) is when Intel really started pulling away from the rest.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_former_IA-32_compatible_processor_manufacturers" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_former_IA-32_compatibl...</a><p>Note: MediaTek is Taiwanese and also fabless. Their phone SoCs are nowhere near as performant as Qualcomm&#x27;s or Samsung&#x27;s, and largely viewed as the low-cost &quot;value&quot; option.
