Pros & cons summary
| Recency | 14 May 2020 | 12 April 2021 |
| Maximum RAM amount | 48 GB | 16 GB |
| Chip lithography | 7 nm | 8 nm |
| Power consumption (TDP) | 400 Watt | 250 Watt |
GRID A100A has a 200% higher maximum VRAM amount, and a 14.3% more advanced lithography process.
A16 PCIe, on the other hand, has an age advantage of 10 months, and 60% lower power consumption.
We couldn't decide between GRID A100A and A16 PCIe. We've got no test results to judge.
Be aware that GRID A100A is a workstation graphics card while A16 PCIe is a desktop one.
