GPUs have a very high memory bandwidth, and can be used to perform memory-intensive operations (think decompression, for example). You can load compressed data up to the GPU, decompress it there, and run very complicated mathematical functions. This can be very beneficial when you run a JOIN operation. See a comparison here, with SQream DB (a GPU accelerated data warehouse) vs. some unnamed data warehousing solutions - https://sqream.com/why-im-not-afraid-of-sql-joins/ https://sqream.com/why-im-not-afraid-of-sql-joins/
