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 | Portable Device Dependent | No outputs |

Pros & cons summary
| Recency | 12 April 2021 | 21 March 2023 |
| Maximum RAM amount | 8 GB | 80 GB |
| Chip lithography | 8 nm | 4 nm |
| Power consumption (TDP) | 80 Watt | 350 Watt |
RTX A4000 Max-Q has 337.5% lower power consumption.
H100 CNX, on the other hand, has an age advantage of 1 year, a 900% higher maximum VRAM amount, and a 100% more advanced lithography process.
We couldn't decide between RTX A4000 Max-Q and H100 CNX. We've got no test results to judge.
Be aware that RTX A4000 Max-Q is a mobile workstation graphics card while H100 CNX is a workstation one.
