Qualcomm Snapdragon 810 processor runs cooler than the Snapdragon 801

Qualcomm Snapdragon 810 processor runs cooler than the Snapdragon 801
Besides offering faster performance while using less energy, a test conducted on the Qualcomm Snapdragon 810 shows that the 64-bit processor actually runs cooler than the Snapdragon 801. Keep in mind that most handsets throttle performance so as to keep the temperature of its skin under 45 degrees Celsius (113 degrees fahrenheit). Room temperature is roughly 25 degrees Celsius (77 degrees fahrenheit). That gives us a targeted range for a chip of 25 degrees to 45 degrees Celsius.

A Snapdragon 801, the chip used on some of 2014's flagship devices like the HTC One (M8) and the Samsung Galaxy S5, runs hotter than the new 64-bit Snapdragon 810. The skin temperature of a Snapdragon 801 powering a commercial handset running racing game Asphalt 8 ran up against the high end of that range twenty minutes into game play. On the other hand, a Snapdragon 810 playing the same game for the same amount of time on a non-commercial handset showed a skin temp 5 degrees lower.

The difference is even more pronounced when measuring the temperature of both processors while capturing video on the respective handsets. A cooler running Snapdragon 810 means a better performing smartphone with a longer battery life. The chip will be used in most Android flagships this year including the HTC One (M9) and the LG G4. Despite talk about the chip overheating, other tests have shown it to be a cooler running component. That has been seconded by LG as the manufacturer calls it one of the coolest processors it has tested.

Thanks for the tip!

This is great news. Hopefully this will be the same once M9 and Z4 are released.

No body cares about a 1% difference in performance that only benchmarks can pick up on.

I am sure that's the modified design as they promised to get Samsung back.

Ha, the real life true phone scores are in and as posted they crap, the lg g fleck 2 scores are going up on YouTube, from real unblocking retail ver, aututu only scores 54251 and geakbenth is 1 core is 1222 and muti core is 3965http://youtu.be/W9IJ6wyjdSM, so as per all my post this is just a dev crap setup and not real test, good look with your crap 810 you going to need it

Prototype G Flex 2 has prototype processor. It wasn't finished. Production ready 810 scores 52000 (with 4K display) or 61500 (with QHD) in Antutu.

Sorry to interrupt but isn't this obvious. At equal workload, a more efficient processor will be obviously cooler.

But SD 810 can go much higher in performance right. So when both perform at their bests, temperatures at that point will be more sensible. Capping a 2015 processor to a 2014 one's performance isn't the wisest thing to do.

It's like what Nvidia did with X1. Technically, the X1 ranges between a TDP of 5-10W( Tablet/car) while Apple A8x has a TDP of 4.5W. However, when X1 deliver similar performance as A8x, it consumes less power. Now will you say that X1 will heat less. No as at it's peak load, it still heats up more than A8x though it provides more performance.

If you limit X1 to the power of SD 810, it will be even more efficient. But that doesn't make it a processor that won't heat up or suitable for phones as that can still reach 10 W at high loads.

It's exactly like saying that if you underclock and undervolt snapdragon 810 to 801 level, it will be more efficient.

Don't be sorry. IMO the end justifies the means. Qualcomm probably has relatively little interest in catering to mobile gaming peasants compared to Apple at the smartphone level. Even when underclocked, the SD810 has the superior connectivity, range of features and it's devices deliver the best battery life. 3 day battery life + powerful camera features >>> crappy Bioshock port for example

The worrying thing is that their competition is not apple, but Samsung. Samsung is using the exact same processor cores, just at a higher clock and superior tech. Their GPU also seems superior( though I'll wait for proper benchmarks) and they usually use better DAC( wolfson), better ISP, codec( Exynos 5433 can record 6K video) and now they finally have a competing modem.

Great point and example

Also what device did they use for this test?
Did they use the MDP phone?
The MDP phone is huge
It looks thicker than the guy's thumb

I'm waiting for reviews of actual consumer phones before making any other judgements

5433 has better DAC but 6k? I didnt see any 6k option in recording menu.

P.S. as per my experience 5433 is more battery hungry than sd805

"Apple A8x has a TDP of 4.5W. "

Yeah. It's stupid to argue over products that haven't been released yet, let alone make comparisons. In another month or two well have all information we need about both chips.

That's wbcause the modem was not setup right for usa networks when it comes to battery

This is the only sensible post in the entire thread. I for one also have a feeling the adreno 430 we've seen thusfar in benchmarks is not representative of the truth. The 430 is supposed to be the real advantage of this chip, instead according to Anandtech it's the weak component. That was a prototype phone so I'm not putting too much weight on it, lets wait and see.

Even if the Enyxos has an advantage over the SD810, so long as the 810 is better than 805 it will be a beastly chip with great connectivity and a huge developer stack behind it. Samsung is banking on the Enyxos more as a strategic move to get more developer support for their architecture. That's the smartest thing Samsung can do at this point, even if their chip isn't necessarily better than the 810. By the looks of it, it will be close.

If you go to the original source in one of the pics it says that Qualcomm put the chip inside a gaming PC case.. lol..

i want to say that exynos 5433 is great and ofcourse its much better than SD805 but the main problem of samsung chips is that i will never ever trust them anymore, samsung said that exynos 5433 is 64bit and it didnt activate it, samsung said that exynos S4 will have all cores run together and they lied in contrast every ability in SD is activated in phones because if acompany didnt activate this ability another competing company will.

Samsung never said 5433 is 64-bit. It advertised it as 32-bit and didn't upgrade.

samsung reanounced it as exynos 7 octa 64bit so its normal for everyone to expect samsung to produce it as 64bit they should warn ppl before they buy it( although many ppl knew that samsung is not going to activate 64bit in exynos to make it in equillibrium with crapdragon).

Yes u agree with your point. As sd810 will be processing a heavier load with QHD going to be the norm for flagships of 2k15 I think the heating issues will Commerce when subject to such loads.

I see qualcomm put money on the table to recover from the reputation damage. Maybe the temperature isn't a problem on the SD810 any more, but something else is.

According to anandtech A57@20nm uses 7,4 watts when running at 1.9 Ghz and 6.5 when running at 1.8Ghz. 
source: images.anandtech.com/doci/8718/A57-power-curve.png

If the SD810 has 4 A57's running at 2 Ghz that would mean the CPU alone uses around 8.3 watts, that is too much for a smartphone. I dont see a phone battery powering a 5watt lcd screen, 8 watt CPU and a GPU that uses even more than the CPU. Maybe for a laptop the SD810 would be good, but for a smartphone you can't expect a 3xxx mah battery to keep it alive for a day.

Ofcource this is only about the max clockspeed, but would you like your phone to lose 2-3% battery per minute while playing a game?

I agree with you but...

GPU is less energy demanding than CPU. I don't think that Adreno 430 wil exceed 4,5 W TDP.

In a high-end game, both CPU and GPU run at the max. CPU is mostly there for the physics.

You're wrong. CPU is nowhere near its limit during gaming. You can check this by yourself easily.

It depends on the game. If the game has heavy physics elements, the CPU will be on it's limits solving the equations and getting speeds and positions and solving collisions.

However, in a more graphic kind of game involving more vectoe and polygons, a GPU will strain more

It is completely dependant on the game.

In a "high end game" with physics calculations and some AI going on, that CPU is working just as hard as the GPU. If your playing farmville, not so much.
