I don't know where to start with this post,you do know that Samsung has and always is 1 whole generation ahead of everyone else right?You do know that Samsung sticks to true arm designs right?
You probably don't know where to start because you apparently don't know enough about the topic.
Samsung does stick with default ARM designs, which means they're
behind nVidia, Qualcomm, Marvell, and Apple. Why? Because the other four have licenses to modify the designs in order to improve on them for the intended purposes.
now who copied Samsung with there purebred exynos 5 that blows the living crap out of everything right now and is nothing more than a purebred arm design right from the makers of arm arch.
Exynos 5 is fast because it's Cortex-A15. But because it's A15, it's also going to be less power efficient than Krait and Swift-based SoCs. Fast isn't everything.
nvidea,qualcomm,TI all use bastard designs and don't stick to pure reference designs like Samsung does,dont you think its odd that the note 2 that is using a exynos 4 arm 9 soc that is almost 3 years old now is keeping up with apples a6 today?
1) TI does the same as Samsung; they also don't have an architectural license, so they're not allowed to customize the designs.
2) Exynos 4 is slower than both the Krait-based Snapdragon S4s and the Apple A6 per core. The only way A9-based SoCs can barely keep up is by higher clocks, higher power consumption, and twice as many cores.

just so you know the galaxy s4 is the first cell phone on this planet to use arms next gen arm 15 cores,they did not copy that from apple,they are using arms pure reference cores and using there OWN fabs to build them and guess what?its 40-60% faster clock for clock then anything out there,or do you somehow think apple can make a better cpu then the people that invented the arm cpus?
Sure Apple can. In fact, ARM was founded as a joint venture by Acorn, Apple, and VLSI Technology. Together, they designed and released the ARM6 family.
snapdragon and apple use hybrid designs and don't use the full potential of arms arch,the a6 is a mix of arm 9 and arm 15 but is no where near the performance of a pure bred arm 15 core.
It's not called "arm 9" or "arm 15"; you must be referring to "Cortex-A9" and "Cortex-A15". Commonly known as "A9" or "A15". Implementations of the ARMv7 architecture.
Samsung and arm teamed up to build the big little arm 15 design,I don't know where you think a fab can just make a chip work and perform in its power envelop without designing the fab and soc to work together from the get go.
go watch Samsung ces on youtube with the ceo of arm talking together on stage how they worked together on big little with Samsung
Samsung didn't do anything special for big.little, they just licensed and built the designs ARM gave them.
arm 15 has been tapped out for well over a year and Samsung had a chip built back in late 2011,now if its so easy like you say it is why don't anyone else use arm 15 big little cores yet?why is snapgragon and a6 not using a full arm 15 design when the blueprints are there for them?
Wrong. An A15 was taped-out in 2011 with TSMC, not Samsung. And taping out doesn't mean it's ready to ship; it only means they built the design. Usually the first several of tapeouts are manufactured for the engineering teams to debug. Many first tapeouts of chips don't even work.
Finally, Snapdragon S4 and Apple A6s don't use a stock A15 because the A15 takes too much power.
A15 typically takes 2x-4x more power than Krait and Swift. (

As the article also says, even if you downclock A15 to lower the power consumption, it's still questionable whether it'd be possible to dissipate the heat in a phone form factor. Now you know why the Galaxy S4 is so huge.
ohh wait,you cant just throw **** on the wall and hope somehow you build a cpu from that.No other fab,not even intel has a skill and fab to be able to build big little and if they did you could of bet your imac they would already of had the soc out.
All wrong. Intel's fab tech far surpasses Samsung's. Heck, Intel's fab tech far surpasses everybody else's. Everybody knows that, even fresh EE college grads. In fact, that's the reason Atom's even able to try to break into the smartphone market at all. Intel doesn't build other people's SoC designs though; why give competitors access to your advantage? All those rumors of Intel fabbing for Apple are just stock analyst fantasy.
As for the "skill to build big.little?" Are you kidding? There's no special skill necessary. Manufacturing-wise, it's no different than any other SoC; it's just cores on a chip.
The fundamental idea behind big.little was thought up decades ago. In the mainframe era. It's not a new idea at all. Besides, it's not even a fresh idea in the mobile space, nVidia's Tegra 3's companion core is an example of that.
