It occurred to me that AMD's recent demo of Zen running an opensource application against Broadwell may reveal more than AMD wanted. The demo showed Zen beating Broadwell by 1-2% while Broadwell was hobbled down to the same 3GHz and turbo mode turned off. Naturally the Faithful went wild with excitement but I thought about it, why would AMD chose a single opensource application to use to compare with Broadwell? Then it became clear.
#1 Without publishing the system configuration or compiler options, no one can verify their results. Had they used a standard benchmark,anyone could see if they get the same results. I suspect they wouldn't See #2
#2 It would not be at all unusual for Zen to still have bugs at this stage of debug that need compiler switches to turn off features or capabilities. Only with a custom benchmark can AMD accomplish this without telling the world what does or still does not yet work on Zen.
