Modern database engines are bandwidth bound. Moving data to and from GPUs is expensive and slow by database engine standards so any performance gain due to higher memory bandwidth is usually lost in the data transfer overhead and much lower effective I/O bandwidth.
Every database co-processor, not just GPUs, have had the same issue.
