UnverifiedIn FP16 format each parameter occupies 2 bytes, while in INT4 format it occupies only 0.5 bytes, theoretically achieving a 4x compression ratio.67% similarUnverifiedINT4 has only 16 discrete values available, while INT8 has 256 discrete values.63% similarUnverifiedFP16使用16位存储数值（1位符号位、5位指数位、10位尾数位），可表示约65000个离散值63% similarUnverifiedTaking the Q4_0 format as an example, every 32 FP32 weights are packed into one quantization block containing one scale factor and 32 4-bit integers, averaging approximately 4.5 bits per parameter, reducing memory usage to approximately 1/8 of the original.63% similarUnverifiedThe NVIDIA A100's theoretical FP16 peak compute is approximately 312 TFLOPS, but GPU utilization in naive LLM inference scenarios is often below 30%.62% similar
