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.

Chip lithography 65 nm 4 nm
Power consumption (TDP) 20 Watt 300 Watt

ION has 1400% lower power consumption.

L40G, on the other hand, has an age advantage of 14 years, and a 1525% more advanced lithography process.

We couldn't decide between ION and L40G. We've got no test results to judge.

Be aware that ION is a notebook card while L40G is a workstation one.
