Connectivity and outputs
Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.
| Display Connectors | No outputs | 3x DisplayPort |

Pros & cons summary
| Recency | 11 January 2021 | 5 October 2020 |
| Chip lithography | 10 nm | 8 nm |
| Power consumption (TDP) | 10 Watt | 300 Watt |
UHD Graphics has an age advantage of 3 months, and 2900% lower power consumption.
A40 PCIe, on the other hand, has a 25% more advanced lithography process.
We couldn't decide between UHD Graphics and A40 PCIe. We've got no test results to judge.
Be aware that UHD Graphics is a desktop card while A40 PCIe is a workstation one.
