Impossible is possible: Intel DG1 graphics card launched on PC with AMD processor
Chiphell forum enthusiast Misaka_9993 was able to run an Intel DG1 graphics card on a system with an ASUS ROG STRIX X570-I motherboard and an AMD Ryzen 7 5700G processor.
The idea was to use the integrated Vega 8 video chip to boot the system, so a processor with integrated graphics was needed. The system was then able to output video to the display through the HDMI port of the discrete Intel DG1 graphics card.
This configuration may be required if you need to use a hardware video decoder in AV1 format. The Intel card does this. At the same time, the AMD Ryzen 7 5700G processor only supports PCIe 3.0, while the card supports PCIe 4.0. So Intel DG1 will work with limitations.
Note that officially Intel DG1 can only work in computers with the latest versions of “blue” processors.
The Baikal processor was compared with the Intel Core i5-10210U – a task was found where the Russian chip is faster
The specialist scalped the AMD Ryzen 7 5800X3D processor,improved its characteristics and found out how it is similar to Intel chips
