qcom needs to get their 820 out stat on Samsung 14nm process.

SoC performance is a mild improvement over Snapdragon 805, and a significant improvement in GPU over Snapdragon 801. However, it’s definitely alarming at how small the differences are when Snapdragon 810 is placed in a phone, and it seems that the thermal output of the Snapdragon 810 is high enough that sustained tests end up placing it somewhere around the range of the Snapdragon 805 in CPU-bound tests. In GPU performance, the improvements over the Snapdragon 805’s Adreno 420 are generally somewhat minimal, which really justifies HTC’s decision to go with a 1080p display for the M9.

In our first few browser tests, we can see that the One M9 posts dramatically lower performance than the Snapdragon 810 MDP/T, which seems rather strange. However, using CPUBurn to try and load just a single thread reveals that without HTC’s CPU cheats, it’s basically impossible to get the A57 cluster beyond 1.5 to 1.6 GHz

The first result that we’ll look at is web browsing on WiFi. To say the least, the M9 posts a result that is a concerning regression from the M8 in this area. Although the One M9 does use the BCM4356 WiFi chipset, it’s highly unlikely that this is the reason why battery life regresses around 18% when the battery is now 9% bigger. Doing some quick calculations would mean that the M9 consumed about an average of 1.22 watts throughout the test. The M8 consumed about an average of .91 watts throughout the same test. This represents a 33% increase in power consumption that has to be accounted for

20nm isn't a shocking improvement, and IIRC, A57 regresses (just like A53) in performance/watt compared to A15, so you small improvements when thermally limited:

Some more hot data/measuraments:
tomsguide.fr
The firmware update decreased the temperature for 11,3C while reducing single thread performance by almost 22%.

Handheld metal device at 57C, are they crazy? That's borderline dangerous for hand burning and nice battery explosions?
