Using a GPU as a numerical processing resource via Thunderbolt or ExpressCard

A CUBE attached to a laptop via Thunderbolt or ExpressCard. The CUBE contains a GPU card. I assume the laptop could use the GPU as a numerical processing resource for OpenCL. Could a user who needs more graphic horsepower use the GPU for that purpose?

The Cube allows any PCIe peripheral to plug into a laptop via PCIe Express Card slots or Thunderbolt slots including GPUs for video or GP GPU rendering. While there are no hardware restrictions on this connection, the laptop BIOS may limit the types of hardware supported over the PCIe or Thunderbolt link. In addition, some peripheral drivers may not support the operating system of some laptops or embedded products with ExpressCard or Thunderbolt ports. For example, a laptop or embedded host system that runs Windows 8 RT may not support a high end peripheral with only a Windows 8 driver.
