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.

Pros & cons summary


Recency 16 November 2023 16 April 2024
Maximum RAM amount 48 GB 8 GB
Chip lithography 5 nm 8 nm
Power consumption (TDP) 275 Watt 50 Watt

L20 has a 500% higher maximum VRAM amount, and a 60% more advanced lithography process.

RTX A1000, on the other hand, has an age advantage of 5 months, and 450% lower power consumption.

We couldn't decide between L20 and RTX A1000. We've got no test results to judge.
