Analysis
The r6i.24xlarge is a memory optimized instance in the r6i series with 96 vCPUs and 768 GiB of memory on Intel Xeon 8375C (Ice Lake) (up to 3.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r6a.24xlarge on AMD EPYC 7R13 costs $5.44/hour, 10.0% less ($442 a month). The other variants are the r6id.24xlarge at $7.26, the r6in.24xlarge at $8.37 and the r6idn.24xlarge at $9.38.
At $6.05/hour on demand in US East (N. Virginia), about $4,415 a month, the r6i.24xlarge is one of the cheaper ways to buy memory optimized capacity: only 16% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0630.
Running it in N. Virginia instead of São Paulo saves $2,628 a month per instance: $6.05/hour against $9.65/hour, a 60% spread.
The newer r7i.24xlarge on Intel Xeon Scalable (Sapphire Rapids) is 5.0% dearer at $6.35/hour.
It is size 8 of 9 in the r6i series. Stepping up to the r6i.32xlarge gives 128 vCPUs and 1024 GiB for $1,472 more a month. Dropping to the r6i.16xlarge saves $1,472 a month.
Looking beyond its own line, 3 of 35 current types with 96 vCPUs and similar memory are cheaper. The cheapest of those is the r5a.24xlarge on AMD EPYC 7571 at $5.42/hour.
