Qualcomm Snapdragon 810 shown to run comparatively cool

Bad thermal reputation may be unjust, but does the 810 SoC overdo thermal throttling?

Re: Qualcomm Snapdragon 810 shown to run comparatively cool

Are they just skin temperatures though? If so, and unless the test devices are identical, it doesn't tell us much about SoC temperature. ~40 seems far too low to be realistic for SoC temp under gaming load though. It doesn't take much for the Krait S4 in my Nexus 4 to exceed 60C under load.

Of course I don't know how true the 'overheating' rumour is, but showing a graph with skin temps on dissimilar devices doesn't prove it either way.

Re: Qualcomm Snapdragon 810 shown to run comparatively cool

Firstly, comparing two different devices, each presumably with different cooling characteristics, is not a fair test.
Secondly, running the same workload is not a fair representation of maximum power draw. Presumably the 810 is capable of much higher performance. What's needed is a comparison of maximum power usage by running a proper stress test program on each device. You can hardly compare device A at 100% vs device B at 50% and claim that because device A is 10% hotter, device B doesn't have overheating issues..

We seem to be dangerously close to a Qualcomm monopoly for current-gen flagship devices, so it would probably be a good thing to have some more diversity for the ARMv8 SoCs anyway TBH.

Mediatek are actually starting to do well. Their MT6595 was a strong performer last year and this year their MT6752 and MT6732 are pretty strong in the mid and low range segments. I'm looking forward to seeing how their MT6795 in the highend segment performs. The only problem is that globally, not many phone manufacturers are using the Mediatek SoCs which is probably because they don't share their kernel source code and thus support for it is pretty crap. Not to mention they are also breaking the GPL agreements by not doing so.

I don't understand why they make good chips and not provide the source code for them. If they did that then I'm sure they'd be more takers for their chips.

I was speaking more about the Western flagship market. Everything seems to use a Snapdragon 800/805 at the moment.

Interestingly a few more non-Samsung devices seem to be using Exynos processors now, e.g. the Meizu MX4 which has just been reviewed by Anandtech.

Charlie has an interesting take on this.

Edit to add: TLDR: He says the overheating rumours were all a Samsung FUD campaign to try and slow their loss of market share. I hope he has really good evidence, or the lawyers will be all over him!
