AMD's Mike Clark, known as the 'Father of Zen,' discussed the upcoming Zen 5 architecture in an interview. Zen 5 will cover both 4nm and 3nm process nodes, with the 4nm chips launching soon. The 3nm variants are expected to follow closely. AMD's compact Zen 'c' cores, designed for background tasks, have been successful in laptops but are not yet planned for desktop chips. However, Clark hinted at their future integration into desktop processors. Zen 5 introduces full AVX-512 acceleration for Ryzen CPUs, a feature Intel has struggled with. Clark explained how AMD achieved this without compromising clock speeds. The conversation also touched on thread placement techniques for workload scheduling and the design optimizations that allow Zen 5 to run AVX-512 instructions efficiently. Clark emphasized the importance of balance in design and power management to ensure optimal performance across different core types. Overall, AMD's Zen 5 architecture promises advancements in performance and efficiency across its CPU product stack, from desktop to data center processors.
