Guys keep in mind the controller doesn't actually show the hashrate of the devices. It uses a similar algorythm pools use to compute your hashrate based on the number and difficulty of shares the device submitted. The more lucky a device has been in the actual interval the more hashrate it will show.

To know their actual performance compared to GPUs we should run one of each on the same network, on the same pool, and draw a graph of how many diffiulty 1 shares they submitted a minute. When I finally get my units I'll do that, and also make a few other graphs like their temperature in ltc mode without a fan, performance at different clockrates etc.
