AMD announces Radeon Pro VII featuring 16GB HBM2 memory and Infinity Fabric Link


The new Radeon Pro features 16 GB of HBM2 memory, which is the same capacity as NVIDIA Quadro RTX 5000, although the bandwidth is much higher (1 TB/s). Unlike the Radeon RX (Radeon VII) model, the Pro variant does not have an HDMI display output. Instead, AMD opted for six mini-DisplayPort connectors which are 8K capable.

AMD Radeon Pro VII is a PCIe Gen 4.0 graphics card, which is not surprising considering all Navi-based Pro models are compatible with the new interface. However, this is an advantage over the Turing-based Quadro RTX series, which are only PCIe Gen 3 capable. It is also worth mentioning that Radeon VII (from RX series) is only PCIe Gen 3.0.

The card has a typical board power of 250W, which is slightly less than RTX 5000 (260W). It requires a single 8-pin and a single 6-pin power connector. This configuration is another difference compared to the RX model, as the card was spec’ed at 295W TBP with dual 8-pin.

AMD is also bringing back a new multi-GPU bridge for the Radeon Pro VII. The bridge is called ‘Infinity Fabric Link’ and it has a bandwidth up to 168 GB/s. AMD is comparing its Infinity Fabric Link with NVIDIA NVLINK which can offer a maximum bidirectional bandwidth of 100 GB/s (for RTX 5000 it is 50 GB/s).

AMD confirmed that Radeon Pro VII features Vega 20 GPU with 3840 Stream Processors. The maximum double-precision compute performance is twice as high as Radeon VII (RX Series). The card will retail at 1,899 USD.
