It is manufactured by its arch Android rival,
They won't allow it

It does provides more evidence to suggest that this whole current gen of '64-bit' Snapdragon's are a rushed, half backed reaction to Apple's going 64-bit.
I think we'll really start to see Qualcomm fight back once the 'Taipan' core is ready, and once it is in production my bet is you'll see that the current 'Cortex' based chipsets get retired very quickly (at least in the high end Soc's)
By all accounts however 'Taipan' is still some way off. Qualcomm should hope that not too much damage is done to their reputation in the mean time.

Qualcomm botched the design of the chip generally, and the memory controller specifically. Consequently, it overheats (just like the 610 and 615) so they've had to reduce the clock rate. The memory controller isn't fixed though, so you'll see massively lower performance numbers for the 810 in multi-threaded tasks than either Mediatek or Samsung's A57 chips ... both due to the memory controller issue and lower clocks due to overheating.
Considering the G3's performance, I don't think LG's definition of something having "no issues" matches the rest of the world's.
Anonymous, 30 Jan 2015LG, it's your chance to dethrone the Galaxy S!! How so? The Exynos will be superior.

They "resolved" the heating issue by implementing heavy throttling.
Will wait 6 months for 14nm SoC's.
Fix is probably lowering the CPU and GPU clocks and thus the performance. I'd rather take 14nm Exynos.
What I would REALLY like to eagerly know is how they fixed it. There's a very simple way to fix overheating issues: Thermal throttling. So they could basically just have dumbed down the processor power to say, Snapdragon 805 level. that's what I'm concerned about. they sell you a device with Snapdragon 810 but in reality it may be just as fast as a 805. Or even worse, maybe it IS as fast as it was supposed to be but that would only last for a few seconds until critical temperature is reached, where the performance drops.

My most recent experience with an Exynos chipset was having briefly owned a Galaxy Alpha, Which could at times get plenty warm itself (granted this was using the previous gen A15/A7 combination) I parted with it mainly due to the inadequate sized battery and resulting poor battery life
I have not read much reporting on the performance of the Exynos version of the Note 4, but will have a look at the article you have linked to, Thank you.

TDP limits and power consumption concerns with stock ARM designs are a big part of why Qualcomm designed their own architectures in the first place (Scorpion/Krait)
The new generation chipsets (808/810) are a knee jerk reaction to Apple's taking things to the 64-bit level ahead of estimated time frames.
As such the Qualcomm have not had time to develop the 64-bit successor to Krait (Taipan I believe it’s called) and is looking to stock ARM A53/A57 cores to plug the gap, it's no wonder they are a little out of their comfort zone and these new chipsets are showing teething problems as a result.
Good of LG to finally admit there is an issue, we’ll just have to see if it has been rectified.
One last thing though, if the rumours are true that Samsung have ditched the 810 if favour of their own Exynos chipset for the upcoming S6, we’ll have to see how they get around these heating issues as the new Exynos is also using an A53/A57 set up (though one would think a move to the new 14nm ‘FinFet’ process may help in this regard)
