Second, the demise of Intel graphics / Arc can be extraordinarily dangerous for Linux, as a result of Intel’s strategy to GPU drivers is the very best for compatibility, wheras Nvidia is actively hostile to drivers on Linux.

Third, Intel is the one firm advertising and marketing consumer-grade graphics virtualization (SR-IOV), and the lack of that will make Nvidia’s enterprise chips the one recreation on the town, which means the common shopper will get much less efficiency, much less flexibility, and fewer safety on their computer systems.
