While not exactly "consumer hardware" - there do exist companies that make and sell neural network hardware; think of it as "embedded research and development" level kind of stuff (in many cases they sell development kits and the like - even to hobbyists who have the cash). For instance: http://www.cognimem.com/index.php http://www.cognimem.com/index.php http://www.general-vision.com/hardware/ http://www.general-vision.com/hardware/ ...and while not inexpensive, and not quite the same as "neural network hardware", Nvidia does sell several deep learning platforms (beyond their GPU offerings): http://www.nvidia.com/object/deep-learning-system.html http://www.nvidia.com/object/deep-learning-system.html http://www.nvidia.com/object/embedded-systems-dev-kits-modules.html http://www.nvidia.com/object/embedded-systems-dev-kits-modul... http://www.nvidia.com/object/drive-px.html http://www.nvidia.com/object/drive-px.html
