In this episode of Talking Tech, we’re joined by Stephen Robinson, Intel Fellow and Chief CPU Architect, who breaks down the front and back-end changes that bring additional versatility to Lunar Lake’s Efficient-cores, codenamed Skymont. Compared to the previous Crestmont generation, Skymont E-cores are deeper, wider, equipped with more L2 cache, and integrated with a fabric that provides access to a new memory side cache. The result is a highly performant low power island capable of running a wider range of workloads with excellent efficiency.
