Llama.cpp Arm NEON kernel achieves up to 6.5x faster prompt processing
November 13, 2026
A new Arm NEON kernel for llama.cpp's tiled K-quant matmul uses SDOT instructions to optimize low-bit quantized models. Tests on Neoverse N1 show IQ3_M prompt processing jumping from 11.5 to 74.5 tokens per second.
