2. What MediaTek, Qualcomm and Samsung have in common is that they all manufacture arm processors, but they don't have the actual architecture design ability. The difference is that Samsung has its own fab, which has the ability to manufacture memory and flash memory. Among them, Qualcomm also has baseband chip manufacturing and R&D capabilities. And the most crucial difference is that in terms of communication standards, Qualcomm belongs to the status of standard-setters, holds a large number of communication patents, and belongs to upstream enterprises. For example, the patent of cdma2000 belongs to Qualcomm, and all terminal devices supporting cdma2000 need to be handed over to Qualcomm to collect patent fees. Samsung and MediaTek, especially MediaTek, belong to downstream enterprises;
3. Intel, Samsung and TSMC all have fabs, all of which are producing cpu and other products on a large scale. Needless to say, only Intel has the ability to develop cpu, and TSMC is the only complete foundry among the three. Samsung produces its own Orion cpu, and also works for Apple and Qualcomm. Intel only serves itself, not OEM.
