Intel has been making significant changes to its mobile CPUs, facing competition from AMD, Qualcomm, and Apple. Meteor Lake and Lunar Lake feature unique chiplet designs and updated P-Cores aiming for maximum per-thread performance. Lion Cove in Lunar Lake has improved performance and energy efficiency compared to Redwood Cove in Meteor Lake. The changes in architecture have led to improved L3 latency and DRAM access with a focus on improving CPU performance. Intel’s Lion Cove architecture features separate schedulers, increased execution ports, and expanded structures like the reorder buffer and floating point register file. Several improvements have been made to handle memory accesses and improve overall performance.
