The CPU is Back: Rethinking the CPU-GPU Split for LLM Inference
Red Hat, Thursday, August 6th, 2026
Red Hat argues the CPU-GPU split for LLM inference deserves rethinking as workloads change.
Red Hat argues that GPUs have dominated the large language model conversation for the past three years, but the picture is changing.
In traditional chatbot applications, CPUs contribute a fraction of the compute per request while GPUs do the heavy lifting.
Newer inference patterns shift that balance, giving CPUs a larger practical role. Red Hat makes the case for rethinking the CPU-GPU split rather than assuming GPU-only scaling.
