Analysis
The x8i.16xlarge is a memory optimized instance in the x8i series with 64 vCPUs and 1024 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 $4,857 a month per instance: $7.00/hour against $13.66/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.16xlarge on AWS Graviton4 costs $6.25/hour, 11% less ($547 a month), though switching means rebuilding software for arm64.
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 $7.00/hour in US East (N. Virginia), or $5,112 for a 730-hour month.
It is size 7 of 12 in the x8i series. Stepping up to the x8i.24xlarge gives 96 vCPUs and 1536 GiB for $2,556 more a month. Dropping to the x8i.12xlarge saves $1,278 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.
