Intel and AMD in the same PC! Yes, the DG1 graphics card was designed to run on an AMD Ryzen PC

Leaked from Twitter 9550pro found a post by Misaka_9993 on the Chiphell forums about the user taking an Intel DG1 dGPU, made by manufacturer GUNNIR, and using it on a system based solely on AMD’s Ryzen platform. The test results are surprising because DG1 discrete graphics cards are incompatible with AMD-based motherboards, or so we thought.

Intel’s first desktop graphics card can now run on an AMD Ryzen PC, but not officially yet!

Misaka_9993 initially sought to buy the Inte DG2 Arc Alchemist graphics card, but the affordability and high cost of Intel GPU is still relatively high in the world. The user decided to purchase the GUNNIR DG1 GPU, offering 80 EUs on board, the first Intel Xe-based GPU released in the second half of 2021. GUNNIR designed the card around the Xe-LP architecture, and the card is the first custom design seen at the launch of Intel’s new architecture. The VideoCardz website mentions that “it should be Iris Xe or Iris Xe Index V2”.

Intel DG1 series dGPUs are not compatible with AMD motherboards by the company. That didn’t stop forum member Chiphell from taking an AMD Ryzen 7 5700G integrated Vega GPU and an ASUS ROG STRIX X570-I motherboard and combining the three to make the DG1 dGPU job.

Misaka_9993 used UEFI and disabled CSM to boot system from AMD Ryzen 7 5700G Integrated Vega 8 GPU. From there, the system can output the graphics signal via the HDMI connection of the GUNNIR DG1 dGPU. This action allowed the user to view two separate GPU-Z windows working together. The AMD Cezanne Vega 8 GPU is shown on the left, while the Intel DG1 dGPU is on the right in the example below.

The Intel discrete graphics card performs much worse than the AMD Vega graphics card as shown below in the AIDA64 benchmark screenshot on Chiphell. This configuration is less typical but proves that the Intel DG1 dGPU can run on an AMD-based motherboard, even with little work. The output given by the Intel dGPU is not ideal for gaming and is only by far decent for media.

Readers should remember that the Ryzen 7 5700G supports PCIe Gen3 x16 while the Intel DG1 supports PCIe Gen4 x8. This test causes the AMD card to minimize bandwidth to 8 lanes instead of 16 lanes.

Even though the cost is much higher, the Alchemist DG2-128-based Arc A380 GPU is the next-gen version of the Intel DG1 board used in the test. Additionally, the card is much harder to find than the Intel DG1, which was the company’s original starting point for creating a discrete graphics card for its systems.
