## Summary

George Cozma of Chips and Cheese joins Bryan Cantrill, Robert Mustacchi, and the Oxide team to discuss AMD's 5th Gen EPYC processor, codename Turin, and Oxide's development of their next-generation Turin-based platform, Cosmo. The conversation covers Turin's high clock speeds, AVX-512 improvements, and SKU stack, while detailing Oxide's hardware design decisions, including power delivery, PCB backdrilling, and the use of p4 programmable networking. The team also shares firmware bring-up challenges, such as resolving reset loops caused by power stage firmware, and explains their use of eSpy boot for system recovery and management.
