Connectivity and outputs
This section shows the types and number of video connectors on each GPU. The data applies specifically to desktop reference models (for example, NVIDIA’s Founders Edition). OEM partners often modify both the number and types of ports. On notebook GPUs, video‐output options are determined by the laptop’s design rather than the graphics chip itself.
| Display Connectors | No outputs | Portable Device Dependent |

Pros & cons summary
| Recency | 22 June 2020 | 1 April 2015 |
| Maximum RAM amount | 40 GB | 8 GB |
| Chip lithography | 7 nm | 14 nm |
| Power consumption (TDP) | 250 Watt | 6 Watt |
A100 PCIe has an age advantage of 5 years, a 400% higher maximum VRAM amount, and a 100% more advanced lithography process.
HD Graphics 400, on the other hand, has 4067% lower power consumption.
We couldn't decide between A100 PCIe and HD Graphics 400. We've got no test results to judge.
Be aware that A100 PCIe is a workstation graphics card while HD Graphics 400 is a notebook one.
