Galaxy S II makes an appearance in Qualcomm’s S4, Thermal Butter Benchmark

Posted on Jun 18 2012 - 3:37pm by Brian

We’ve previously written about Qualcomm’s S4 chipset and how its appearance in the U.S. versions of the Galaxy S III is not a downgrade from the Exynos Quad. Well here we have yet 1 more reason to laud the S4 as it shows its vastly improved efficiency over the previous generation of dual-core processors

As you can see, Qulacomm is quite proud of their 28nm chipetset which will be featured in the new Galaxy S III. About 20 seconds in, you can see the tops of the 3 phones in this test:

If you look closely at competitor B, you can make out the outline of the Galaxy S II’s rectangualar camera assembly with side-by-side lens and LED flash. The 3.5mm jack is in the right position as well. Check this image for comparison:

The good ‘ol Exynos 4210 shows off its butter melting prowess as it cooks its way through a stick with its 1.2GHz, 45nm dual cores. Based on the video, it looks like the Exynos, whose semiconductor technology is 60% larger, melts butter about 5x as fast as the S4. If I got my calculations correct, it appears that or every 1nm increase in semiconductor size, the ability to melt butter increases by 29%. Now I’m no electrical engineer, but if these numbers hold constant for the Exynos quad (32nm quad-core) then it should melt butter at 29% x 4nm x double the cores, or… 232% faster than the Qualcomm Snapdragon S4.

Let’s ignore my calculations for a bit and look back at the test results and what it means in real world scenarios. When I run my Galaxy S II at full load playing a game such as Destroy Gunners, the phone actually becomes so warm that it is uncomfortable to hold. If the S4 chip can run the same game but 5 times cooler, that is an amazing feat. Now back to my calculations which state that the Exynos Quad may run twice as hot under full load. That’s still relatively not that hot–as its only half as hot as the Galaxy S II’s Exynos dual-core under full load. Certainly will be warm, but shouldn’t get your jimmies all rustled.

Any of you guys manage to get your hands on both a S4 and Exynos Quad device? Which one runs hotter; we’d love to hear your conclusions below!
