Analysis
The g4ad.16xlarge is a gpu instance instance in the g4ad series with 64 vCPUs and 256 GiB of memory on AMD EPYC 7R32 (up to 2.8 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Running it in N. Virginia instead of Tokyo saves $885 a month per instance: $3.47/hour against $4.68/hour, a 35% spread. It is not offered in São Paulo, Mumbai, Singapore and Sydney, so plan around that if you need a presence there.
It carries 4 GPUs with 32 GB of GPU memory, so most of the price is the accelerator rather than the CPUs. It has local instance storage (2400 GB NVMe SSD), which is fast but lost when the instance stops. Network: 25 Gigabit.
At $3.47/hour on demand in US East (N. Virginia), about $2,532 a month, the g4ad.16xlarge is one of the cheaper ways to buy gpu instance capacity: only 7% of the 78 current gpu instance types cost less per vCPU-hour than its $0.0542.
It is the cheapest of the 2 processor variants AWS sells at this size and generation. The g4dn.16xlarge on Intel Xeon Family costs 25% more, and no others also sit above it.
It is the largest of the 5 g4ad sizes. Dropping to the g4ad.8xlarge saves $1,266 a month. Unit price is not flat across the series ($0.0542 to $0.0946 per vCPU-hour), so the size changes the rate you pay.
