| Maximum RAM amount | 12 GB | 80 GB |
| Memory bus width | 384 Bit | 5120 Bit |
| Memory clock speed | 6008 MHz | 2 GB/s |
| Memory bandwidth | 288.4 GB/s | 1,280 GB/s |
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 | No outputs |
