Cubix Corporation announced today its new GPU-Xpander Mobile product for Apple iMac and MacBook products which feature Intel's high-performance I/O connectivity Thunderbolt technology. The new Xpander Mobile, which is based largely on Cubix's existing GPU-Xpander PCIe slot expansion technology, will initially feature one PCIe x16 slot (x4 electrical) and one PCIe x8 slot (x4 electrical), plus a 175W power supply. The Xpander Mobile is designed, like all other Cubix Xpander models, with an open architecture allowing users to add or remove OS X-compatible PCIe I/O controllers at will.
