Hi, we'll shortly be able to test how a CORTEX-M7 single core architecture holds up against 700D performance demands in the UHSDR firmware (STM32F7@216 MHz and STM32H7@400Mhz). And for sake of completeness, we can test it with a STM32F4 @ 168 Mhz but I don't have high hopes here...
For the 800 Mhz for the A4-5000, I think this is current frequency when running the cpuinfo command, not necessarily the frequency when the processor is doing 700D (unless the command was called at the right time). A4-5000 ha 1.5Ghz max clock.
