Intel: IPEX and AMX
Intel has aggressively 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 claims a 400% performance uplift for LLM inference through advanced auto-tuning and INT4 quantization support.
Convergence
The next frontier is combining algorithmic sparsity with hardware-level quantization. This ecosystem promises a future where AI is ubiquitous, private, and capable of running on the infrastructure the world already owns, rather than the infrastructure it is waiting in line to buy.
