Intel: IPEX and AMX
Intel has integrated AI acceleration instructions (AVX-512, DL Boost, AMX) into its silicon. The Intel Extension for PyTorch (IPEX) allows standard models to leverage Advanced Matrix Extensions (AMX)—essentially small matrix multiplication accelerators built directly into the CPU core.
AMD: ZenDNN
AMD's ZenDNN is a deep neural network library optimized for EPYC and Ryzen processors. ZenDNN 5.0 reports significant inference gains for selected LLM workloads through auto-tuning and INT4 quantization support.
Convergence
A key direction is combining algorithmic sparsity with hardware-level quantization. This trend can improve privacy and lower deployment costs by running more workloads on existing infrastructure.
