Latest commit enables simultaneous SME and NEON kernel execution, dramatically boosting performance on Apple's latest M-series chips.
The open-source project llama.cpp, maintained by the ggml-org team, has released a significant performance update with commit b8269. The core technical advancement is the implementation of concurrent execution for SME (Scalable Matrix Extension) and NEON kernels. These are specialized instruction sets on ARM-based processors, with SME being a newer extension for advanced matrix operations crucial for AI workloads. Previously, these might have run sequentially; now they can operate in parallel, better utilizing the CPU's capabilities.
This optimization is specifically highlighted for macOS and iOS on Apple Silicon (arm64), meaning it directly benefits users of Macs with M1, M2, and M3 chips, as well as modern iPhones and iPads. The commit is part of a broader release that includes updated builds for multiple platforms, including Windows with CUDA 12.4/13.1, Linux with ROCm 7.2 and Vulkan support, and openEuler. For Apple users, the change translates to faster token generation and more efficient local AI model inference when running compatible models through the llama.cpp framework, effectively getting more performance out of the same hardware.
