NVIDIA RTX 6000 Ada
NVIDIA GeForce RTX 4070 Ti
NVIDIA GeForce RTX 3090

 NVIDIA RTX A5000
NVIDIA Quadro RTX 6000
NVIDIA GeForce RTX 4070
NVIDIA GeForce RTX 3070
NVIDIA GeForce RTX 2080 Ti
Storage space3 3 GB
Video output 1 x DisplayPort 1.4
USB connectivity 1 x 10 Gbps USB-C 3.1 Gen 2 or USB-C 3.2 Gen 2

The USB port must be directly connected to the chipset. Alternatively, required USB connectivity can be achieved with a compatible PCIe expansion card.
Operating system Windows 10 (64-bit)
Windows 11

1 Note that the GPU requirements may vary based on use case and required graphical quality.

2 AMD graphics cards are currently not supported.

3 Storage space required to install Varjo Base.

Note about laptop graphics cards

Laptop graphics cards with identical names can perform differently depending on factors such as the thermal design of the laptop and amount of memory on the card.

Some key terms to keep in mind when comparing graphics cards:

  • Total Graphics Power (TGP): The maximum power consumption of a graphics card, which gives an indication of its maximum performance.
  • GPU memory: Graphics cards come in many variants with different amounts of memory on the card, which also affects performance.

See below for hardware requirements when using XR-4 with a laptop computer.

Component Recommended
Processor (CPU) 13th Gen Intel Core i9-13900HX or better

XR-4 requires a chipset that supports high throughput USB connectivity with multiple IN transactions. List of compatible Intel and AMD chipsets
Chipset XR-4 requires a chipset that supports high-throughput USB connectivity with multiple IN transactions.

Intel chipsets with USB multiple INs support:
600 series, 700 series

See list of all compatible Intel and AMD chipsets.
Memory (RAM) 32 GB
Graphics card (GPU)1, 2 NVIDIA RTX 5000 Ada (150W TGP or more)
NVIDIA RTX 4090 (150W TGP or more)
Storage space3 3 GB
Video output 1 x USB-C to DisplayPort adapter or 1 x Mini DisplayPort to DisplayPort adapter

Note that the adapter must support 8k video and DisplayPort 1.4 with Display Stream Compression (DSC).

The adapter must be connected to a port that is routed directly to the dedicated NVIDIA GPU. If using a USB-C to DisplayPort adapter, the port must also include support for Alternate Mode.

See the list of verified USB-C to DisplayPort adapters for more information.
USB connectivity 1 x 10 Gbps USB-C 3.1 Gen 2 or USB-C 3.2 Gen 2

The USB port must be directly connected to the chipset.
Operating system Windows 10 (64-bit)
Windows 11

1 Note that the GPU requirements may vary based on use case and required graphical quality, and while mobile and desktop GPUs may have identical product names, performance is significantly lower when using mobile GPUs.

2 AMD graphics cards are currently not supported.

3 Storage space required to install Varjo Base.
