[Android] The 810 is Back to Settle Things Out, We Don’t Buy It Yet

Can't say I'm surprised at this. But this is also entirely the OEMs' faults. They're all jumping on the Snapdragon train despite the face the locomotive is going over the cliff. People should remember there also Exynos and MediaTek SoCs out there. And given the recent performance (or lack there of) of the 810 at half throttle, this alternative SoCs are probably looking pretty appealing right about now.

 

Isn't the 820 supposed to be coming to flagships soon? 810 is like so last year.

 

Is that what Qualcomm's blueprint is?

Each successive SoC: twice the power and 4 times the overheating.

 

Actually the smaller the fab, the less power it consumes while having better performance. The part of the problem is the chassis and insufficient cooling.

 

That's why I like HTC and their metal chassis. If HTC could insulate their battery, then they could possible bond their SoC to the chassis with thermal paste, making the back chassis one large heatsink.

 

Give me a break. Even HTC had to "fix" Qualcomm and their mess by changing the higher cores to 1.6GHz... Not really a fix.

But Qualcomm has always run hot... This time they panicked in the face of Exynos and grabbed an off the shelf ARM design and fabbed it...

I welcome someone to unseat Qualcomm but it won't be a company that doesn't have access to the old ATi Imageon tech... End of story. I wish Qualcomm would bury the 8xx series like nVidia did after 880M disaster (funny how that works... Look at all 8-prefixed products from everyone... All a mess...) And release the 910 with an Adreno that can take on M1... Because we all know nVidia makes great chips... But can't get them in devices... And when they do,like the G2x, it ruins that brand for life. Never again LG. I'll go back to a green screen Nokia and snake before you get my money again after you abandoned us and made us all go buy the Sensation!!!!!!!

 

All the tegra chips sucked something awful...save the K1 in the Shield tablet. Does that mean I will never but another Nvidia gpu or phone with an Nvidia tegra chip.

Not necessarily.

 

The Tegra 4 was a decent chip, imo. Good performance overall with decent enough battery and cooling. Great CPU + GPU as well even though Nvidia always really oversell their GPUs in that they big them up a lot and they're often still bested by the Mali chips.

 

The Tegra K1 was a real step in the right direction for Nvidia. They still have a long way to go to improve the Tegra line, but I'm holding out hope.

I can't stand Qualcomm SoC's anymore. They're getting to be overpriced for subpar performance.

 

Tegra still fails for thermals and battery life. That is where Exynos and Snapdragon crush Tegra. My fiance's Tegra Note 7 averages like 3 hours of screen on time when gaming or less. With video playable only it hits maybe 4 hours.

 

Battery life always. Even my step cousin's Nvidia shield with it's Kepler Tegra still sucked down power quicker than a recovering alcoholic on a booze cruise.

But thermals...?

Need you be reminded of just how the Snapdragon 810 "performs" under load at stock clocks?

Like I said, I'm holding out hope for the Tegra. Its got a long way to go, but it's definitely heading in an improving direction. We will have to see how the Tegra X1 performs with it's Maxwell cores as opposed to Kepler cores.

 

Right but think of some of the devices where they stuck the 810. The M9 I don't think was properly cooled. And the Nexus 6 doesn't have the same thermal issues as the M9. Tegra 4 and the Shield run pretty toasty. And the K1 chip has active cooling. Sure Nvidia is going in the right direction, but I'm sure they don't make a profit on ARM based SoCs considering how much they pour into it. And that doesn't seem like a viable business plan.

 

The shield tablet's not actively cooled. At least I don't think it is. You may be thinking of the original Nvidia shield. This is the one my step cousin has and let me fool around with.

Any and all competitors to Qualcomm are welcome in my mind. I honestly think the X1 could be a real competitor because one thing that every manufacturer has failed at is graphics... Tegra has smashed every comparable offering in that department since the 2... NVidia needs to work on power consumption and heat... Maxwell may be the answer to that...

 

Yep, the Xperia Z5 is rumoured to come with an S820 in September, but Sony is rarely first and has been unwilling to innovate as of late, so maybe the November time frame for the Xiamoi Mi 5 is more in line with realism.

I think the hate for Qualcomm will subside since the S820 is once again packing custom cores. One thing is clear though: Qualcomm will have to do more than get desperate if they want to remain the go-to SoC supplier for high-end ARM devices.

EDIT: We're talking announcements in Q4, not actual availability this year. For that reason, another source claims that the S820 will miss the Mi 5 and only find its way to the Plus model.

 

Nvidia needs to do what Qualcomm does, work with OEMs of phones as well as Google to get some sort of synergy, TBH otherwise they will never get the smoothness of iOS. Exynos is good but they are only really found in Samsung flagships. KNOX is a pain to deal with.

:\ Z5 eh. I don't understand the hate for Qualcomm. I can't see Samsung being the go to SoC supplier for Exynos. Not to talk about those 2/3 tier ARM SoC makers.

 

Couldn't have said it better. My thoughts exactly. And exactly why I never bought Samsung after they put KNOX on the S3 without telling anyone. T-Mobile doesn't care about tripped flags but Samsung also breaks ROM compatibility across SKUs needlessly which means that the T-Mobile models always get the shaft in ROMs

 

I will have to find where I read it, but I remember an article that stated the Nexus 6's SoC was dialed back for "compatibility reasons". I read that as cooling issues. And if the M9 isn't properly cooled with an aluminum backing, then that's a seriously design flaw.

Ehhhh...working with OEMs...I think that's why Qualcomm's chips are starting to falter. Too many cooks.

I think that's also why the Apple chips work so well with iOS. It's all under one roof, so it doesn't have to worry about all the little nuances that comes with multiple OEMs.

 

My Nexus 6 has a Snapdragon 805 based on the Krait 4xx series... It has no heat issues unless it's rapid charging. My Motorola turbo charger actually has three charging states... When it's at the highest, when the battery is closest to dying, battery temp reads as 115F... Which means CPU is close by... But that's nowhere near the 155F that the 810 was hitting in the M9 which is basically a big heatsink... Before HTC cut the core on the A57s... My 805 can stand up against the 810 quite well actually... With a fresh clean install it pulls 49-50K in AnTuTu. It gets wrecked by the S6 though. In everything except graphics. Mali can't stand up to Imageon/Adreno

The thing that should be most embarrassing to SoC makers... Qualcomm has barely tweaked the base ATi code with each release... They haven't gone all out with what they can do because they have no reason to. Apple's chip is superior in the graphics... But Qualcomm owns the android market. Nobody comes close. They've been rebranding since the adreno 3xx... Which honestly wasn't much of a boost over the 2xx... In terms of tech advancement...

NVidia is the sole exception... Their Tegra line has decimated the graphics... But been garbage for everything else... If they can make some sort of dynamic recompiler like emulators use... And make 64 bit CUDA code out of Android apps... With a Maxwell 128-256 core (depending on heat constraints and price) chip, they could really bring a wrecking ball into the mobile world. Obviously dynamic recompilers are not perfect and there would be incompatible apps but that's what legacy ARM is for. Maybe I'm talking out of my backside but if Google has transitioned from Dalvik 32-bit to ART 64-bit via Tegra K1... It really doesn't seem that far fetched to convert ART 64-bit to CUDA 64-bit in theory.

I think it goes back to what Tsuname said. The M9 wasn't engineered to cool the 810 properly. But I think the 810 was running warm to begin with. I also don't think the problem with the Galaxy line graphics lies with the Exynos or Mali chips. Two words: Touch Wiz

No, you're not talking out of your backside. Google transitioned from dalvik to ART for a reason. There's only so much optimization that can be done with dalvik due to the bottlenecking inherently caused by JIT. ART with its AOT will be able to take greater advantage of the jump to 64 bit. But coding to CUDA will require Nvidia to work with Google to properly implement it. And apparently that's just not happening right now.

Hope and pray, hope and pray...
