The original BCM2837 was a terrible chip because the cooling is of old style so the PCB can't transport enough heat away and the package was plastic insulating from an eventual heat-sink. The Pi 3+ and 4 changed that. BCM2836 is the real deal, peak SoC for non GPU + SD card duty: https://wikimovel.com/index.php/Broadcom_BCM2836 https://wikimovel.com/index.php/Broadcom_BCM2836 https://en.wikipedia.org/wiki/ARM_Cortex-A7 https://en.wikipedia.org/wiki/ARM_Cortex-A7
