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 1 September 2020 22 March 2022
Maximum RAM amount 10 GB 80 GB
Chip lithography 8 nm 4 nm
Power consumption (TDP) 320 Watt 350 Watt

RTX 3080 has 9.4% lower power consumption.

H100 PCIe, on the other hand, has an age advantage of 1 year, a 700% higher maximum VRAM amount, and a 100% more advanced lithography process.

We couldn't decide between GeForce RTX 3080 and H100 PCIe. We've got no test results to judge.

Be aware that GeForce RTX 3080 is a desktop card while H100 PCIe is a workstation one.
