Analysis
The x8i.xlarge is a memory optimized instance in the x8i series with 4 vCPUs and 64 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it very memory-heavy at 16 GiB of memory per vCPU.
Running it in N. Virginia instead of São Paulo saves $304 a month per instance: $0.4377/hour against $0.8535/hour, a 95% spread. It is not offered in Canada Central and London, so plan around that if you need a presence there.
Within the same generation and size, the x8g.xlarge on AWS Graviton4 costs $0.3908/hour, 11% less ($34.21 a month), though switching means rebuilding software for arm64. The other variants are the x8aedz.xlarge at $1.15.
Per vCPU it is one of the dearer memory optimized types: 84% of the 385 current types in the family cost less than its $0.1094 per vCPU-hour. The premium mostly pays for the extra memory per vCPU. On demand it is $0.4377/hour in US East (N. Virginia), or $319 for a 730-hour month.
It is size 2 of 12 in the x8i series. Stepping up to the x8i.2xlarge gives 8 vCPUs and 128 GiB for $319 more a month. Dropping to the x8i.large saves $160 a month. Unit price is not flat across the series ($0.1094 to $0.1269 per vCPU-hour), so the size changes the rate you pay.
