Why does the RealSense SDK require a 4th gen+ Intel Processor?

[Granger_L_]

I'm genuinely curious. It appears that it is not just due to a performance difference, as certain functionalities simply don't work properly if a processor below 4 gen is used.

Can someone provide some technical details as to what 4th gen+ Intel processors have or are capable of that the RealSense SDK cannot get from a 3rd gen processor?

Thanks!

From what I've read it seems that to achieve real time performance some parts of the SDK use special CPU instructions only available from that generation.

So, if your CPU does not have those instructions, those features of the SDK will simply not work instead of working slower for example.
