PRODUCT DESCRIPTION
NVIDIA NVLink Bridge 2-Slot for RTX A6000 / RTX A5000 (supplied by Leadtek) - Local Warranty
Link Two RTX A6000 or Two RTX A5000 Cards
The NVIDIA NVLink Bridge 2-Slot connects two identical NVIDIA Ampere professional GPUs — two RTX A6000 or two RTX A5000 cards — with a direct high-speed GPU-to-GPU link. For Singapore design, simulation and AI teams already running Ampere workstations, it is the way to get more out of a two-card setup.
Up to 112 GB/s Between GPUs
NVIDIA rates NVLink on the RTX A6000 at 112.5 GB/s bidirectional bandwidth with a single bridge, far more than the cards can exchange over the PCIe bus. In NVLink-aware applications, a pair of RTX A6000 cards can work with a combined 96 GB of GDDR6 memory (48 GB with two RTX A5000s), allowing larger renders, simulations and models than one card can hold.
2-Slot Spacing — Match It to Your Motherboard
This bridge is for GPUs installed in PCIe slots two slots apart (adjacent dual-slot cards with no gap between them). If your two cards sit with one empty slot between them, you need the NVIDIA NVLink Bridge 3-Slot instead. The A-series bridges are low profile, enabling NVLink in a wider range of chassis.
Not for RTX PRO Blackwell or RTX Ada Cards
NVLink is not supported on NVIDIA RTX PRO Blackwell or RTX Ada Generation workstation cards, so this bridge will not work with them. It also cannot link two different GPU models — both cards must be identical.

Specifications are taken from NVIDIA's NVLink bridge page and the RTX A6000 and RTX A5000 datasheets. Fields NVIDIA does not publish are shown as such rather than estimated.
Compatibility & Applications
| Supported Pairs | 2x RTX A6000 or 2x RTX A5000 — both cards must be the same model |
| Also Listed by NVIDIA | NVIDIA's compatibility table lists the same Ampere NVLink bridge type for RTX A5500 and RTX A4500 pairs — ask us to confirm before ordering for those cards |
| Not Supported | RTX PRO Blackwell cards, RTX Ada Generation cards, Quadro RTX (Turing) cards (which use their own Quadro RTX NVLink bridges), GeForce cards, and mixed GPU pairs |
| Slot Spacing | Cards installed two slots apart (adjacent dual-slot cards) |
| Software | Scaling performance and memory with NVLink requires application-specific support; NVLink is also supported in NVIDIA RTX Virtual Workstation (vWS) software |
| Typical Uses | Large-scene GPU rendering, CAE/CFD simulation, scientific visualisation and AI workloads that can use NVLink memory pooling or peer-to-peer transfer |

Frequently Asked Questions — NVIDIA NVLink Bridge 2-Slot
Which cards does this bridge work with?
Two identical NVIDIA RTX A6000 cards or two identical RTX A5000 cards. It does not link two different models.
Does it work with RTX PRO Blackwell or RTX 6000 Ada?
No. NVLink is not supported on RTX PRO Blackwell or RTX Ada Generation workstation cards.
2-slot or 3-slot — which do I need?
It depends on your motherboard's slot spacing. If the two GPUs sit in adjacent dual-slot positions, use this 2-slot bridge. If there is one empty slot between them, use the 3-slot bridge. We can check your motherboard layout for you.
How much bandwidth does NVLink add?
NVIDIA rates it at 112.5 GB/s bidirectional for the RTX A6000 (up to 112 GB/s on NVIDIA's bridge page) with a single bridge.
Will my software automatically see one big GPU?
No. Performance and memory scaling over NVLink requires application-specific support — check that your renderer, solver or framework supports NVLink before buying.
Does it come with local warranty in Singapore?
Yes. This NVLink bridge sold by SourceIT comes with local Singapore warranty and a GST invoice.
