Analysis
The x8i.64xlarge is a memory optimized instance in the x8i series with 256 vCPUs and 4096 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 $19,426 a month per instance: $28.01/hour against $54.62/hour, a 95% spread. It is not offered in Canada Central and London, so plan around that if you need a presence there.
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 $28.01/hour in US East (N. Virginia), or $20,447 for a 730-hour month.
It is size 11 of 12 in the x8i series. Stepping up to the x8i.96xlarge gives 384 vCPUs and 6144 GiB for $15,136 more a month. Dropping to the x8i.48xlarge saves $5,112 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.
Windows Server roughly adds 42% to the bill at $39.79/hour, because the licence is charged per vCPU.
