microcontroller chips/boards capabilities online database?

Does there exist any online searchable database of microcontroller chips/SOCs/dev boards that allow you to search by their capabilities/specifications?

I'm looking not only for Arduino brand, but also myriads of other manufacturers like Atmel/Microchip, Raspberry Pi, STM, SparkFun, Espressif, or even small productions like Teensy or whatever.

Something like these webpages, but for all manufacturers and in database-searchable form instead of table form:
https://www.arduino.cc/en/Products/Compare

Ideally something like NewEgg's computer components "power search" would be ideal!

cheers,
