The Snapdragon processors downclock as a safety measure, not just downclock on its own. When it reaches a certain temperature (I think it is 50 or 55 Celsius), it downclock as not to cause damage to it. I know that devices that run at 1.5 GHz, go to 810 MHz. Other stock speeds, I don't know...

thats the problem that exist on snapdragon more than others, the performance is not very consistence. Mediatek claim that they might not have the best benchmark score but they manage to keep the performance steady. If theres anything Qualcomm should do, this should be the first issue they look into.

Is there any UI overhaul on the horizon?

I'd really want a facelift, the UI although praised for being close to Vanilla is getting kinda boring to look at. Or it's the wallpaper that makes it look like so.
Anyway, MartenR is that from Questionable Content?

pretty useless even if they can clock it up to 3GHz when there is constant down clock whenever it gets hot. Problems with snapdragon for a while. Thats why mediatek look promising because they manage to solve that at least according to them anyway. I think someone told me nVidia charge too much for their tegra so its never really popular among the OEM, I guess thats why we barely see much of Tegra 4. And they never seems to be as good as nVidia has claim either.
Actually, what makes Tegra 4 rare is coz of it's high power consumption While NVIDIA did something smart by having that companion core, but in most cases that core is only running while the phone is in standby... while idle the SoC will switch to the 4 A15 Cores... and while These cores can scale good from low to high depending on the task, A15 by it self even in the lowest state consume too much for a mobile SoC.. even if only one core is enabled...
ARM know this and that's why they started with the idea of LITTLE.big they designed A15 to be high-performance ( that's why it has Out-Of-Order arch. ), and this kind of performance comes with high power demand even in it's lowest state... basically A15 can't scale well in the low side of power it's not efficient at these low power, so ARM designed A7 to fill that gap in the low side...
This is the exact reason why you didn't saw any A15 quad only SoC in the wild, Dual A15, Quad LITTLE.big or Octa LITTLE.big...
And just remember Samsung first pathetic take in the OctaCore in the S4 ( i9500 ), the switching between both A15 side and A7 wasn't perfect, and early firmwares was horrible in battery life as the driver sometimes will not switch back to A7 making the chip A15 quad and eating the battery life in no time, not to mention the overheating which was another dark side of that faulty driver which Samsung shipped in retail product !!

OT
Don't you think LG's use of girls for promoting their products is a little excessive. Numerous times I've seen people talking about the girls rather than their products in comment section.
I just feel bad when I see this kind of advertisment is actually very successful.

Thought nVidia said the companion core is use to handle stuffs like music and video playback, any demanding task will use the main processor. I mean Sony did the same with Vita design, all the music and video playback are done by the media engine 2.

Yes, There's no problem with that, but the problem is with normal usage, when we use apps, SoC will scale the clock speed depending on demand... but even with very low demand from regular apps that does not require a full of A15 power the A15 won't be able to scale it... it's like running a Core i3 @1GHz and compare it to Atom @2GHz and both for just doing simple things that the Atom @2GHz is just more than enough... Core i3 @1GHz will still consume a lot of power compared to Atom @2GHz... that's why Intel didn't make Core i3 for mobile even when running at 500MHz.. they needed a different Architecture for such usage...
The companion core isn't enough for things which sits between Music/Video and other high performance things it's weaker than these needs so the SoC will switch to the A15 by that time...
If A15 was good at scaling then NVIDIA won't need a companion core at all, they can just run one of these A15 cores at lower clock like 500MHz and it will be enough... but A15 @500MHz is not as efficient as A7 @500MHz..
If NV wants something to fix it, they need a better companion core or cores actually as newdays even some simple tasks like browsing the net are multi threaded and imagine how good Android is in multi-tasking then you will know you need more than just one companion core for it...
The reason for NV to not go for multi core A7 and put just one core is because their GPU needs too much die space, and adding 4 A7 cores will make the chip very large and not economic also ( more expensive for an already expensive chip )...
it's like how AMD Fusion APU's ( even the newest one Kaveri ) isn't available yet in 8 cores because the iGPU is too big to add more general purpose cores...
basically Tegra's GPU is not small die friendly and it's not designed from ground to be a mobile GPU core, compared to Mali, Adreno or PowerVR...
To have an idea, This is Tegra K1 die shot
http://media.bestofmicro.com/J/6/416706/original/tegra-die.jpg
Here's Tegra 4 die shot
http://cdn.androidpolice.com/[....]nexusae0_Tegra-4i_die_shot.png
And here's Apple A6 ( note that these are modified ARM dual cores )
http://cdn.cultofmac.com/wp-c[....]s/2013/04/apple_a6_dieshot.jpg
And Here's Apple A7 ( Again, modified dual ARM cores, but note that additional GPU Core )
http://cdn1.appleinsider.com/13.09.27-A7_Transistor.jpg
And finaly, this is Exinos5 Octa core ( Note, while there's no mark of the GPU area, but just compare the ARM cores to other areas, GPU should be in the right or top-left side of the SoC )
http://kizumi.files.wordpress.com/2013/05/hc0rbtc.jpg
compare all these.. the CPU side to GPU side.. and see how much GPU performance you get compared to the die area...
