The GPU may help in compressing and decompressing data, encrypting and decrypting as well as sorting it (block-wise) ahead of heavy operations. Compressing and decompressing are examples of reducing I/O, and shifting it over to compute instead - and the GPU is ideal for that. Most decent columnar databases are compute bound. I/O is less of a bottleneck compared to OLTP style databases.
