Analysis
The r5.xlarge is a memory optimized instance in the r5 series with 4 vCPUs and 32 GiB of memory on Intel Xeon Platinum 8175 (up to 3.1 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r5a.xlarge on AMD EPYC 7571 costs $0.2260/hour, 10% less ($18.98 a month). The other variants are the r5ad.xlarge at $0.2620, the r5d.xlarge at $0.2880 and the r5n.xlarge at $0.2980.
At $0.2520/hour on demand in US East (N. Virginia), about $184 a month, the r5.xlarge 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 $110 a month per instance: $0.2520/hour against $0.4020/hour, a 60% spread.
It is 5.3% cheaper than the older r4.xlarge on Intel Xeon E5-2686 v4 (Broadwell), so staying on the previous generation costs more as well as being slower.
Looking beyond its own line, 6 of 45 current types with 4 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.xlarge on AWS Graviton2 at $0.2016/hour.
It is size 2 of 8 in the r5 series. Stepping up to the r5.2xlarge gives 8 vCPUs and 64 GiB for $184 more a month. Dropping to the r5.large saves $91.98 a month.
