Check the video. It clearly shows how performance drops significantly the moment you run out of vram. It doesn’t meant the performance will be perfect in 1440p, it means Intel is using that as a competition ground, something the 8GB cards fail at and maybe Intel’s GPU isn’t great but the 12GB will probably make a difference (and Intel is maybe being quiet at 1080p because they are likely to perform worse).
