CPU - Intel® Xeon®¶

AMD Zen CPUs

On AMD Zen 4 / Zen 5 CPUs, AMD Zen optimizations are auto-enabled when the zentorch package is installed. All models supported by vLLM on CPU are supported on AMD Zen as well; model compatibility does not change. This page reflects the current CPU reference validation matrix on Intel systems. See AMD Zen optimizations for details.
