I agree that power consumption is an issue, however it's always an issue no matter what the application may be. Lower power is always better than higher, and it is seen today as a much more important consideration than it was just 10 years ago. As for vehicles, what I wanted say, is that the computing power needs are growing very quickly and it has already become a constraint especially on EVs. Unless something drastically changes with the technology, we're not going to have true self-navigation capabilities on a device as low powered as a cell phone is, however given the high investments going into "AI", we can expect advances that bring down the power needs to more practical levels. As for what kinds of computing devices are used inside emebbed applications, it all depends on the application. In many cases an ASIC will do, in others an FPGA is needed such as with space exploration devices, in other cases a GP CPU or GPU is required - it depends entirely on the needs. The EPYCs in our case are designed for fault tolerant longevity and other abilities such as support for NVDIMM memory. You can google up what Siemens uses the processor for, and also Advantech, these are two design wins mentioned by AMD.
What started the whole discussion is definitions, for example "edge" is not always well defined, it generally means a kind of application involving communications or data processing (it's a fuzzy thing), but "edge" can include the use of an embedded application, for example computing near a cell tower is an edge device that uses embedded computing.
