GPUs have phenomenal memory bandwidth (multiple terabytes per second in a multi-GPU server) in addition to the computational parallelism they are known for. MapD caches the most recently touched data in the VRAM across multiple GPUs, meaning it can execute scan queries over billions of records in milliseconds.
