[Bill Davis] "A LOT of the new speed is clearly due to X being optimized for the new R9 GPU in the new Retina MacBook Pro, but I honestly didn't expect THIS much of a boost. It bodes well for what all computer manufacturers can accomplish when they truly optimize tasks like intensive video editing processes to the latest advances in hardware as those appear."

I think it's important to note that as designed, the primary factor in this test is actually H.264 compression, not the rendering pipeline. I'd bet Apple is using Intel Quick Sync [link] to accelerate H.264 compression, and I'd bet Adobe is not.

Quick Sync is a hardware feature of recent Intel Core consumer-class processors, but not on of Xeon workstation/server processors. Look at the original data:

Note in the test data how a MBP running FCPX shames a nMP running FCPX by a factor of almost 6x! On the nMP, where Quick Sync is not a variable and the test is a slightly purer pipeline comparison, Pr actually outperforms FCPX by about 20%!

I'm not saying that knowing the speed of H.264 compression isn't important or that Apple's use of Quick Sync is not relevant; it is. But I do think this test as currently designed does not support your hypothesis that the results are driven by the new GPU.

I would, however, agree with your conclusion (assuming you're talking about software developers moreso than computer manufacturers, as there is only one company in our industry where that Venn diagram would overlap).
