Pixel Experience CAF
CAF stands for the Code Aurora Forum. It’s the place where Qualcomm releases source code for their phone processors. It’s directly supported by Qualcomm and it’s generally a more optimized branch for Snapdragon phones.
Now, there are two mainlines for Qualcomm chipsets. We have CAF, and we have AOSP.
CAF is what Qualcomm provides to all hardware vendors, as references and documentation on the chipset. Because of this, almost all non-Nexus devices are running HALs, kernels, etc from the CAF line.
AOSP is direct from Google. Google will take a fork from the CAF like, and add or retract features that they deem necessary, and then produce that for Nexus phones.
So, what this means is CAF ROMs will likely perform marginally better, but they are lacking features added by Google’s AOSP line.
