Snaprdragon S4 thermal efficiency shown off using... butter

Snaprdragon S4 thermal efficiency shown off using... butter
Smartphone owners have probably noticed that their handsets get pretty warm at times, especially when their processors are pushed to their limits. The guys at Qualcomm, however, want to convince you that the Snapdragon S4 chipsets are different. How do they do that? With butter, of course!

Here is the proof: in the video below you will see a Snapdragon S4 smartphone alongside two handsets of similar rank. All of them get wrapped in transparent plastic, and a slab of butter is placed on top. To no surprise, the competitors easily turn the butter into liquid while the Snapdragon S4 manages to keep things relatively cool. That is thanks to the chip's 28-nanometer architecture, which makes the silicon substantially more power efficient than the competition while keeping its performance up to par. 

Now feel free to check out the video itself – the fun part begins around the 0:50 mark. Of course, do not hesitate to tell us what you think about Qualcomm's test by dropping a comment.

The one on the left was a Galaxy SII (international) and the one in the middle was a Droid Razr Maxx (possibly just a Razr).

If 2 competitors here are quadcore, and each of them is reachingits limit, the result is incorrect. Let's wait fo the announcement of OMAP 5 and EXYNOS 5 dual core to see the true competition

no, lets not wait for them to come out. The thing is that qualcomm has already managed to bring a15 chips to market whereas samsung and others haven't. Exynos 5xxx will be superior when it comes out though.

I love it when someone says "lets wait for this and lets wait for that" S4 is allready here and it is kicking ass, so you wait for your dream chips that will come in 6 months or so, I'm happy with krait. And who knows what will Qualcomm have in their corner in 6 months, than when competitors make their a-15 duals I will say let's wait to see what will Qualcomm have in 6 months, right now S4 is the best there is and it is likely it will stay like that for some time.

We have to wait because there is no 28/32nm dualcore smartphone in the market now for comparison, understand?

the SGS3 uses a 32nm quad core processor that is very heat and battery sensitive. Notice how they didnt use that phone.

Yep. Temperature and battery of S3 is much much better than S2.

No we don't. The competition is whatever's on the market right now. If someone has the choice right now between an S4 powered device and a device that isn't, the two can and should be compared. And until more A15 powered phones arrive there is no more valid comparison.

Using butter was a neat idea but there are a number of other factors that are also at play here like the design of how each phone's internals are put together and build quality in what the phones are made of. It's a clear mark against the plastic construction of the SGS2 whereas the Razr and One S spread the lower amount of heat generated more evenly. And apart from not knowing what apps were being run on the phones, the competitors were likely running Gingerbread instead of ICS.

Competition A looks like the SGS2 while Competitor B is the RAZR, it's just my guess based on the shapes of the phone though. . .

I believe this, my galaxy nexus gets so hot at the camera it hurts to touch sensitive areas. I was watching netflix and I set the phone down on my bare legs (shorts hiked up, hate that) and I thought I dropped a cigarette on my lap.

and all three phones are running the same task? what if other two are running some heavy task and the one with s4 is just on standby? (although i know that s4 is more efficient but still...)

snaprdragon? new kind of snapdragon ith "r" in the middle?

Its the snappier version of snapdragon. BaDumTsh!

I wonder how Tegra 3 devices would perform in such a test. My father's HTC One X could easily boil an egg after 15 minutes of mild to decent usage.

it would have been nice to see what program they were all running. One program does not heat up as much as another. Great. its the coolest chip. Its still no where near the most powerful. Get a case, and you wont notice as much anyways. :)

Well he did say at peak performance. So any program that gets the processor at peak performance should do the job. I hope the phones were set to GTA III. lol remixfa are you getting a Samsung Galaxy S III? I know you are still rocking an original Samsung Galaxy S. Did you hear the nice & tasty rumor of the phone I want the Samsung Galaxy Note II? I was salivating when I heard a 5.5" Super AMOLED HD screen with a WOPPING 360ppi. Also the sick dual-core Exynos A15 with 1.5GB of RAM. I really think it will be 2GB though because all US Galaxy S III will come with 2GB of RAM. It's June & I already have the money READY for the Samsung Galaxy Note II.

yea, i dont think im going to wait for the Note. Its still just too big for me I think. I put the first Note in my pocket and it was very noticeable to me. I love the specs though. I guessed the note would rock the A15 since it has a higher resolution and comes out in the fall. Had a talk with the wifey about the SGS3 last night. If we can swing it, she's going to let me get an unlocked international version next month depending on if this area has been refarmed for 1900mhz 4g yet. She loves me. :) :) If not, I may break down and get the S4 version on Tmo depending on how its synth benchmarks go. There really isnt anything else out that catches my eye ATM.

I hear you on the Note, but you do get used to it. You are coming from a small Galaxy S at 4". I have my Samsung Galaxy Nexus & going to the Note was a difference but not as big of a difference. It was big on my pocket but it wasn't uncomfortable. I just can't wait to get that phone. I have been talking about it for quite a long time.

i dunno.. maybe. I've always had the big n bulky phones.. windows phones, large texting phones.. that Storm with a case on it was massive and heavy.. My SGS1 is so thin and light and unobtrusive. When I work out I leave it in my pockets as im jogging and its not a big deal. A super sized phone would definitely be noticed more. It would have to have some fantastic feature to get me to go back to that big like Star Wars style holographic imaging. the SGS3 is just past my limit probably, but not so far that I cant get past it. Maybe after I get used to the size of that, the Note 3 wont be so big to me.. lol. If they announced all those specs and features in something thats like 4.5 inches I'd probably buy that in a heart beat.

Yup, my Galaxy S2 can cook an egg when playing high end games like NOVA...

Why did Qualcomm compare their NEW 28nm process chipset with competitors' OLD 45nm process chipsets? That's pretty fair, isn't it?

21. remixfa

Posts: 14605; Member since: Dec 19, 2008

because if they compared it to the SGS3 with new 32nm exynos and new battery saving tech, they wouldnt have had such a dramatic comparison.

my guess is that the SGSIII was not available.. at that time..

Now slap some bacon on top of Competitor B, and we've got a party!

I can't believe they use butter! Great way to test it how hot the CPU gets though
