Exynos 7420 - A Closer Look at Samsung's New SoC

2015-03-10
this episode of Android Weekly is brought to you by domain.com so you remember all the ruckus that was made about the Snapdragon 810 overheating well it turns out to be a lot of hot air and some believes that that hot air was a false rumor created by Samsung itself to help generate buzz regarding its own system-on-a-chip the beast that is the Exynos 7420 so let's look at that puppy a little closer as expected this samsung galaxy s6 is another industry-leading flagship smartphone especially when it comes to hardware packing in some of the latest and greatest pieces of mobile tech this time though Samsung is opted to exclusively use its in-house Exynos 7420 system on a chip rather than a Qualcomm processor as it is done in previous years so let's devil into the specifics one of the Exynos 7420 s big talking points has been the move down to a 14 nanometer FinFET manufacturing process which puts samsung ahead of Qualcomm's 20 nanometer Snapdragon 810 because when it comes to manufacturing size smaller numbers are better as shorter transistor distances consume less energy and boost processing speeds however smaller closely packed transistors can lead to current leakage between parts of a chip an issue that FinFET manufacturing addresses by enclosing the conducting channel in a thin silicon fin for the same processor design lower power consumption means heat room for increasing clock speeds or additional power savings which will help explain some of the capabilities of Samsung's chip as we dive deeper the bulk of Exynos 7420 s processing components are rather familiar though it's built from arms reference cortex a 57 and a 53 CPU cores at a quick glance the design is very familiar to the Galaxy Note Exynos 54:33 chip thanks to the smaller manufacturing process Samsung has been able to up its clock speeds to 200 megahertz on the GPU side and 72 mega Hertz on the GPU side working out to a very rough 10 percent increase over the Exynos 54:33 and while this will inevitably lead to some performance gains the biggest changes have been made to the system on a chips memory and GPU specifications but the GPU is where Samsung has implemented the largest performance gains over the Exynos 5 series as well as the clock speed increase Samsung has scaled up the number of GPU cores from 6 in the note 4 to 8 in the s6 and this extra graphics grunt will come in handy when gaming on the galaxy s6 is qHD display comparing our own galaxy s6 benchmark tests against the galaxy note 4 we see a rather substantial increase when it comes to 3d graphics performance at 2560 x 1440 now benchmarks don't indicate real-world performance but it certainly confirms the areas in which Samsung has managed to make significant improvements with performance up and consumption down Samsung's push for a 14 nanometer has clearly paid off and it's clear why the company chose to drop Qualcomm Snapdragon Series this generation although CPU performance is only marginally better than some existing flagships additional GPU performance and battery savings are precious improvements for samsung's qHD galaxy s6 so in yesterday's show I made the effort to find a new domain name that was interesting and new one that I haven't talked about before so I just grabbed the first one I saw ishka having no idea what it meant but it turns out it means a genteel girl or woman especially one who attracts a Jewish man I don't need any Jewish men thank you I'm good but I do need a good domain name extension he knows there could be a lady out there who wants to be the Android ishka just not me because it's not just about ComNet org anymore you now have the opportunity to name your site or build your brand in ways never before possible choose from a growing list of more than 200 domain name extensions like ninja NYC expert org club in this case dot ishka all available now at domain.com and the guys who domain.com want to hook our viewers up with a great offer save 15% off domain names and web hosting when you use our coupon code Android at domain.com check out don't forget 15% off when you use our coupon code Android when you think domain names think domain.com alright thanks for watching all you Android sheesh cos love to connect with you right here on Google+ or Twitter as usual and you don't wanna forget about these guys these guys work so hard to deliver the best content on the web your source for all things
