No what I mean is some of these hardware features are not easily applicable to certain GPUs ...
Implementing direct render target reads from the pixel shader on discrete GPUs from AMD/Nvidia has no simple solution whereas mobile GPUs have had that feature for sometime now!
And similarily mobile GPUs struggle to get programmable vertex attribute fetching and bindless textures/resources ...
