Form factor & compatibility
Information on A40 PCIe and Quadro P520 Max-Q compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
| Interface | PCIe 4.0 x16 | PCIe 3.0 x16 |
| Length | 267 mm | no data |
| Width | 2-slot | no data |
| Supplementary power connectors | 8-pin EPS | None |
VRAM capacity and type
Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.
| Memory type | GDDR6 | GDDR5 |
| Maximum RAM amount | 48 GB | 4 GB |
| Memory bus width | 384 Bit | 64 Bit |
| Memory clock speed | 14.5 GB/s | 5.5 GB/s |
| Memory bandwidth | 695.8 GB/s | 44 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 | 3x DisplayPort | Portable Device Dependent |
