Form factor & compatibility
Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop graphics cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).
| Interface | PCIe 4.0 x16 | PCIe 4.0 x8 |
| Length | 267 mm | 168 mm |
| Width | 2-slot | 1-slot |
| Supplementary power connectors | 1x 16-pin | 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 | GDDR6 |
| Maximum RAM amount | 48 GB | 16 GB |
| Memory bus width | 384 Bit | 128 Bit |
| Memory clock speed | 2250 MHz | 1563 MHz |
| Memory bandwidth | 864.0 GB/s | 200.1 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 | 4x DisplayPort 1.4a | No outputs |

Pros & cons summary
| Recency | 13 October 2022 | 10 November 2021 |
| Maximum RAM amount | 48 GB | 16 GB |
| Chip lithography | 4 nm | 8 nm |
| Power consumption (TDP) | 300 Watt | 60 Watt |
L40 has an age advantage of 11 months, a 200% higher maximum VRAM amount, and a 100% more advanced lithography process.
A2 PCIe, on the other hand, has 400% lower power consumption.
We couldn't decide between L40 and A2 PCIe. We've got no test results to judge.
