Analysis
The inf1.6xlarge is a machine learning asic instances instance in the inf1 series with 24 vCPUs and 48 GiB of memory on Intel Xeon Platinum 8275CL (Cascade Lake), which makes it compute-heavy at 2 GiB of memory per vCPU.
It carries 4 GPUs, so most of the price is the accelerator rather than the CPUs. Storage is EBS only. Network: 25 Gigabit.
At $1.18/hour on demand in US East (N. Virginia), about $861 a month, the inf1.6xlarge is one of the cheaper ways to buy machine learning asic instances capacity: only 12% of the 13 current machine learning asic instances types cost less per vCPU-hour than its $0.0492.
Running it in N. Virginia instead of São Paulo saves $562 a month per instance: $1.18/hour against $1.95/hour, a 65% spread.
It is size 3 of 4 in the inf1 series. Stepping up to the inf1.24xlarge gives 96 vCPUs and 192 GiB for $2,585 more a month. Dropping to the inf1.2xlarge saves $597 a month. Unit price is not flat across the series ($0.0452 to $0.0570 per vCPU-hour), so the size changes the rate you pay.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.7440/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.5670/hour, 52% below on demand.
