First, you pretended that you didn't hear of any high-performance ARM design, despite many being announced in many places.

Then you ignored the specs given to you for one of those designs.

Now you ignore any announcement made about "memory capacity": native support for DDR4-2400MHz, "about the same memory bandwidth as a Sandy Bridge Xeon E5", a maximum of 64 GB of memory for SoC...

Stop pretending this is low-end territory, it is not:
