The test has been performed on an iMac Core 2 Duo 2.4 GHz. While it takes 160 seconds for the hardware to encode a video file into HD video 720p for the Apple TV, the Turbo 264HD reduces it to 62 seconds, while the previous model of Elgato H264 key would help completing the work in 106 seconds.
For encoding a video into 1080p, Core 2 Duo alone performed the job in 399 seconds whereas when associated to the turbo H264HD it took only 92 second. So the performance level and the gain are rather huge, and PowerPC-based Mac users will for sure be disappointed to hear that this device is only compat
