How dare Nvidia use Samsungs bench mark patent... :P

Samsung cheats in benchmarks and now they sue Nvidia? A new low.

AnonD-136279, 12 Nov 2014Can you imagine how far the tech world would have advanced ... moreAdvancement would be a lot slower. There would be no such thing as industry pressure to get product out the door. There would be no competition to try and outdo one another and create the best and cheapest products.
That's one of the reasons why collaborations by multiple universities hardly ever lead to new breakthroughs, but national competitions in which there is a reward at stake is when breakthrough innovations are created.

darkgamer, 12 Nov 2014Note 4 uses cortex a57 not a15. Also it can run all 8 cores... moreWho cares? Multicore is just gimmick.
The single core performance is the most important thing about CPU. And Nvidia and Apple CPUs are much better in single core performance.

They are skewed in the power of 3, but would be accurate weren't it for the 8 simultaneous cores in Note 4 (where I only accounted the 4 of A57).

I'm not disputing the methodology given by ARM (which is per core per MHz). Infact, that is what I'm advocating. When you use per MHz, you are taking frequency out of the equation.
Example:
Core A reports 2 DMIPS/Mhz
Core B reports 4 DMIPS/Mhz
Since both are reporting per Mhz, we can conclude that core A is higher performance than core B. If, however, results are reported without normalizing to some base frequency (as below), you wouldn't be able to conclude which core is better, without knowing the operating freqency.
Core A reports 4 DMIPS. (operating @2MHz)
Core B reports 4 DMIPS. (operating @1MHz)
Now Core A and Core B seems to be at par, but, for the same result, Core B is operating at lower freq (thus lower power). Thus core B is better.
Therefore for clarity, it is better to report iso-frequency results.

uf, 12 Nov 2014For comparing performance of different CPU core designs, it... moreActually no.
First of all these are a majorant (for Shield) and minorant (for Note 4). They aren't meant to be an exact representation of performance, just an exercise to show if the claims could be -- in any way, shape or form -- possible.
The methodology you dispute is the one given by ARM, which is stated exactly like this (per core per MHz).
The point that Note 4 can run the 8 cores simultaneously is indeed something which I didn't account for, hence it basically nullifies the OP (like already stated in the reply before this one)

However I did not account for the 8 cores running simultaneously, which would indeed turn things completely around! (as in no longer being in the realm of a possibility that a nVidia Shield could be faster)

Can you imagine how far the tech world would have advanced if all these companies actually worked together instead of trying to take each other out in silly "mine is bigger then yours" games?!

Shield actually runs at 2.2GHz (not 2.4GHz like I've accounted before) so the end result is more like 35 than 38.

uf, 12 Nov 2014It's actually pretty simple to understand which of the two ... moreCortex A15 may perform up to 4.01 DMIPS/MHz per core (depending on actual implementation) while the Cortex A57 starts at 4.1 DMIPS/MHz per core.
Given the Note 4 has a clock disadvantage (1.9GHz vs 2.4GHz) doing the math we get at least 31.16 * 10^6 DMIPS for Note 4 and up to 38.5 * 10^6 DMIPS for nVidia Shield.
As such I don't believe things are as linear as you try to put.
