But that just begs the question: does Broadcom have any parts on the shelf such that, if they tweaked them and sold them to the RPi project at cost, they'd fulfill those requirements? Broadcom and the RPi project can do some things in conjunction that Nvidia, for example, cannot.
However I’m not much into the hardware design, I only write some embedded software for those things. Might be reasons why it’s still too expensive: if the chip requires too many layers in the PCB, too many external components (like RAM), too much electrical power so it needs better PSU and some cooling, and so on.
