FP16 and Int8 are about how many bits are being used for floating point and integer numbers. FP16 is 16bit floating point. The more bits the better the precision, but the more ram it takes. Normally programmers use 32 or 64bit floats so 16bit floats have significantly reduced precision, but take up half the space of fp32 which is the smallest floating point format for most CPUs. similarly 8 bit integers have only 256 total possibilities and go from -128 to 127.
