The only reason Nvidia weren't caught cheating is you can't find Tegra 4 in any devices worth mentioning.

So, nVidia is the only honest OEM/device maker who is not cheating. :hmm:

Yeah, I guess that's pretty much true.The only reason Nvidia weren't caught cheating is you can't find Tegra 4 in any devices worth mentioning.
from a commenter said:"With the exception of Apple and Motorola, literally every single OEM weve worked with ships (or has shipped) at least one device that runs this silly CPU optimization."

Technically, they should have included NVIDIA too according too their own chart as one of the non-cheaters... but then again, they barely make a blip on the map right now.
LinkAnand's reply to the commenter said:I didn't because I didn't go back and test the older Tegra 3 devices, but as you point out there's not a ton of Tegra 4 stuff out right now.
I would have thought the same, but in many sub-tests of GB3 the MT vs ST speedup reaches 4, though not in all (but other factors would obviously prevent perfect speedup).I don't think Tegra 4 will run all CPUs at 1.9GHz under any circumstances for any duration of time whatsoever, even in Shield. So if that's what you're looking for you won't see it. nVidia has always defined different max clock speeds depending on how many CPU cores are active.
Crazy to see that cheating is the norm. I would like to see Apple tested too.
We started piecing this data together back in July, and even had conversations with both silicon vendors and OEMs about getting it to stop. With the exception of Apple and Motorola, literally every single OEM weve worked with ships (or has shipped) at least one device that runs this silly CPU optimization.

Link.Apple doesn't do any of the frequency gaming stuff, no.
LinkWe have some internal tools to poke around at frequency, A7 appears to behave honestly. I explored this issue with engineers at a couple of different companies who were also interested in finding out the answer. Finally, much of what I used to characterize the A6/A7 aren't publicly available, so there's no gaming there.
