Analysis
The g5.8xlarge is a gpu instance instance in the g5 series with 32 vCPUs and 128 GiB of memory on AMD EPYC 7R32 (up to 2.8 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Within the same generation and size, the g5g.8xlarge on AWS Graviton2 costs $1.37/hour, 44% less ($785 a month), though switching means rebuilding software for arm64.
Running it in N. Virginia instead of São Paulo saves $1,251 a month per instance: $2.45/hour against $4.16/hour, a 70% spread. It is not offered in Singapore, so plan around that if you need a presence there.
The newer g6.8xlarge on AMD EPYC 7R13 is 18% cheaper at $2.01/hour, which makes the g5.8xlarge hard to justify for new deployments.
It carries 1 GPU with 24 GB of GPU memory, so most of the price is the accelerator rather than the CPUs. It has local instance storage (1 x 900 GB NVMe SSD), which is fast but lost when the instance stops. Network: 25 Gigabit.
It is size 4 of 8 in the g5 series. Stepping up to the g5.12xlarge gives 48 vCPUs and 192 GiB for $2,354 more a month. Dropping to the g5.4xlarge saves $602 a month. Unit price is not flat across the series ($0.0640 to $0.2515 per vCPU-hour), so the size changes the rate you pay.
