The secret of Snapdragon 810 keeping cool? 50 shades of thermal throttling on the G Flex 2
Samsung might have been wise to go with its own 14nm Exynos for the Galaxy S6 not only for business reasons - using its own superior SoC - but also because of reports that the first batches of Qualcomm's Snapdragon 810 could not keep their cool the way the TSMC foundry was producing them.

Qualcomm went on a PR offensive after the reports, which is extremely rare for the company, touting the Snapdragon 810 virtues with LG, Sony, Motorola and others all lining up behind the chip maker, saying that they will all use the powerful silicon in their upcoming flagships. Reports poured in that the overheating issues are overcome, and mass production is now slated for mid-March, in time to go into all those HTC, LG, Sony and other high-end models tipped with the chipset. There were even reports the other day that Snapdragon 810 runs a tad cooler than Snapdragon 801 in last year's flagships.

The thing is that all those benchmarks and temperature measurements we saw recently are done on Qualcomm's reference Snapdragon 810 platform, which is a thick pieces of a slab, not on a thin retail flagship where heat matters. Well, there is only one of those on the market with Qualcomm's first Snapdragon 810 batch inside - the LG G Flex 2 - and someone decided to run the cross-platform Geekbench on the handset to see what will happen. Here's what happened from the first to the ninth run of the test:

1. 1215 / 3683, 2. 1112 / 3249, 3. 895 / 2931, 4. 672 / 2414, 5. 692 / 2465, 6. 675 / 2421, 7. 663 / 2356, 8. 617 / 2263, 9. 558 / 2065

As you can see, thermal throttling of the processor speed kicked in as soon as the second pass, while at the last try the single core result went down in half, and the multicore mark diminished more than 30% in order to prevent overheating, which wouldn't bode well for gaming and other strenuous processing activities on the thin curved handset, if all units are like that. 

Other than this incident, the G Flex 2 proved pretty capable, at least in the comparison with the Snapdragon 805 in the Note Edge you see below, beating it by a tad in most scores. When it comes to Samsung's new 14nm Exynos 7 Octa that will be in the Galaxy S6, well, things are getting dicey for Qualcomm's finest.

WHY DID YOU COMPARE APPLES WITH ORANGES? IS BIG DIFFERENCE BETWEEN THIS 2 PHONE'S !!! BIGEST IS THE DISPLAY FROM SAMSUNG.
PUT ON SAMSUNG NOTE 4 THE DISPLAY FROM LG AND THEN YOU WILL SEE THE SCORE!

that's offscreen test so resolution doesn't matter

Interesting. When the S6 launches, let's see how the new Exynos fares in the same testing scenario.

Wow, that garbage cpu started throttling after 2nd run and after 3rd ran it was already over.

Barely beats a QHD note in some benchmarks. A true testimony to 810's awesome engineering :D.

That is why I always to people, let's wait & watch. Note with qhd screen is going better here. The 810 is a rushed up Soc. Samsung decision was crucial as they dropped it entirely this year. It's better for community support too.

Thats... sad.

The light becomes brighter on the reasons why Sammy said no-go with this chip for the first time in 5 generations of Galaxy S.

Even the old Exynos 5433 can beat this...

Maybe it's better for manufacturers to stick to Snapdragon 805 at the moment?

Samsung we offer them 5433 in 64 bit mode (7410) when they get all there 810 returned

I'm praying that this only happens on the G Flex 2

Where are those Qualcomm fanboys who said we're butthurt trolling people? Deal with it. Snapdragon 810 just sucks no matter how Qualcomm try to cover it.

Looks like I'll have to wait for Taipan. Nah, screw it. Intel will probably have a working Cherry Trail SoC or Nvidia with a X1-level smartphone SoC with a Maxwell GPU (on Samsung's 14nm or TSMC's 16nm process) ready before 2016. Dang it, Qualcomm!

WTF are u people getting excited about? I admit that the benchmark results are not the greatest, but that doesn't mean anything. Let's all just calm down and wait for the M9 vs GS6 results.

Lol FOOL! If you're still in denial, you'll be in denial when the M9 comes out

As the m9 will only have a 1080p screen if Samsung get even a close better score or the same or a small down score on it the htc will be doa, but sorry to say but the Samsung cpu will kill it doa with a better score, ha the 32bit samsung cpu note 4 kills hit doa and how old is that thing, if I was htc I be phone up Samsung and asking for the 7410 (64bit ver 20nm) asap

I'm definitely not getting a Snapdragon for my next phone, that is sure. Maybe Intel or Nvidia or even Samsung, but not Qualcomm.

So you guys prefer that everyone using Android to use the same S6 with exynos instead of having some competition!? I believe that this someone who did the test with the g flex 2 has been paid big bucks by shamesung to post the results of an unoptimized and prototype g flex 2 running an alpha S810!

With numerous rumors regarding delays and issues. Reference device provided by qualcomm to anandtech also showed mediocre performance compared outside of graphics bench

I have a flex 2 in front of me, i work at sprint and we just got a demo. I ran the test a bunch it did drop after a the first test and did keep getting worse. I also don't know how to prove that i have one in front of me right now. I could upload a pic but im not sure how.
