These instances offer up to 15% improved price-performance and 2.5 times more memory bandwidth than prior Intel-based compute-optimized generations. Gains include up to 20% better overall performance versus C7i, with specific speedups of 60% for NGINX, 40% for AI recommendation models, and 35% for Memcached workloads.

C8i-flex instances provide flexible sizing for applications with partial compute utilization, while C8i targets high-CPU workload scenarios with large instance sizes and bare metal configurations. Availability in Europe broadens access for compute-focused cloud users.
