For integrated graphics, that can happen.
Practically all discrete GPUs are connected through PCI-e, and serving memory requests through that would slow things to a crawl. PCI-e 4.0 with 16 lanes has 32 GB/s of bandwidth. A Geforce 1050 has more memory bandwidth than that (84 GB/s), and that GPU is not high end.
