UnverifiedQuantization precision directly affects memory usage and image quality: 4-bit is small in size and suitable for devices with limited memory, 8-bit has higher precision, and FP16 is close to original precision but has the highest hardware requirements.77% similarUnverified4-bit quantization (such as bitsandbytes NF4 or GPTQ) weights are usually stored in blocks, with each block carrying a scaling factor and zero point, and these metadata are often stored in FP16 or FP32; embedding layers, output layers, and normalization layers may remain at higher precision, so the actual weight file is typically 5%-15% larger than the theoretical P×b/8 value.77% similarUnverifiedFP8相比BF16可提供约2倍的内存带宽节省和更高的矩阵计算吞吐74% similarUnverifiedFP8 is a format that stores weights and/or activations in 8-bit floating point numbers, with VRAM and memory usage approximately twice that of 4-bit quantization.72% similarUnverifiedThe memory and computing power available on edge devices are often measured in MB and milliwatts, differing from data center GPU clusters by several orders of magnitude.71% similar
