GPUs use high-bandwidth RAM, such as GDDR6 or HBM2. These specialized RAM GDDR6 and HBM2 are designed for the extremely parallel nature of GPUs, and can provide 200GBps to 1000GBps throughput. In comparison: a typical DDR4 channel can provide 20GBps. A dual channel desktop will typically have under 50GBps bandwidth to DDR4 main memory.
