Qualcomm throttles its Snapdragon 810 processor just to stay cool?

We recently wrote about how the Snapdragon 810 doesn’t overheat, but what if it really does?

As it turns out, Qualcomm’s top of the line processor might just be throttling it’s performance just to stay frosty, which might be very well the reason why Samsung decided to drop it it’s home-brewed Exynos chips. Qualcomm is indeed trying to shed it’s overheating perceptions but Samsung has probably made the right choice.

However, as explored by GeekTech, it doesn’t look to be all it seems as benchmarking test seem to say that we aren’t getting the whole picture. Granted that they did release that their devices would have a skin temperature limit of 45°C and that it is indeed cooler than their last device, but their reference device looks like it might be misleading the scores as it’s much thicker and probably has better cooling than your average smartphone. AnandTech didn’t find any issues with the SD 810 either, so it’s a little puzzling, because their tests did show a good 33% boost over the SD 805 and GFXBench results tell us that there was only about 10% performance increase as opposed to the 30% claimed by Qualcomm.

David from AndroidPolice also ranted about a device that he can’t mention (likely to be a LG G Flex 2) with benchmark scores that deteriorate greatly after each iteration of testing. This indicates that the processor is capping it’s full potential as it starts to heat up. It’s akin to putting a leash on a horse in the middle of a race and that really doesn’t bode well for Qualcomm.

Thanks to Fish for the heads up!

I'm just gonna say it like it is. qcom got lazy and too big for their shoes until now it's that simple. They're riding on their SD80x/ARMv7 gen SoC success w/ their head so high in the clouds right now in the upper midrange and even flagship space upstarts like MediaTek and Huawei's Kirin are bringing some serious heat they won't be able to ignore come 2016. The only saving factor here is that both MT and Kirin are mostly shunned by devs and even savvier users for lax of open source OR less dev interactive than qcom but that's still a matter of time. All they've been doing has been about jacking up both Krait and Adreno for higher res screens that's it not for OS or apps.

Every single OEM that's dependent on qcom with plans to go full aarch64/ARMv8 this year were caught flat footed since end of last year. Regardless of the 32 bit vs. 64 bit arguments, the shift is happening YESTERDAY or rather that day when Apple outed their A7/Cyclone cores. I'm no Apple fan and they've only begun to mandate 64 bit apps this month this year but that goes to show the importance of timing the groundwork. If it's taking Apple this long over a limited array of their strictly walled garden iDevices, imagine the looming headache for Android's 64 bit debut and its consequent spread out over the vast expanse of multiple sys reqs? I'm thinking it's gonna be at least 2 years out AFTER the 1st 64 bit build and that's me being cautiously optimistic.

As for Samsung's decision at dropping SD810 there's 2 actual possibilities. 1. As a top qcom customer probably running into over tens of millions USD spent at this point (if not more) and if I were Samsung naturally I'd be very pissed off if they handed me samples that fails the prelim tests as that's highly likely the gist behind this story so 2. if Samsung already have an ongoing own SoC program w/ spent R&D millions on top of own fab process advancement, there's the luxury right there to put a foot down and say "You know what? No thanks buddy we'll build newer Exynos into the mix from now on so we got this". No brainer.

This is a good thing actually for qcom to reassess their ongoing 2K/4K res insanity train and start to seriously tackle for proper 64 bit design wins above all in the batt life efficiency department. Only thing they need to worry about is whether or not Samsung decide to go all out against them and sell Exynos out to OEMs that's when the real pain is gonna come. And if Samsung doesn't there's always MediaTek and the injured gorilla Intel.

Admin, i found this but you need to translate it http://www.frandroid.com/marques/lg/265902_pre-te…
its shows the Snapdragon 810 isnt much improvement compare with Snapdragon 805

Gotta feel for LG a bit though. I'm thinking that they don't have much options for this 2015 rel window. Their Odin/Nuclun project isn't scaling up well the way Exynos can.. This and guess what G Flex 2 is gonna be locked tighter than a 3rd rate Chinese brand won't be helping either.
