Samsung Galaxy S5 (octa-core) - user opinions and reviews

Little insight in big-LITTLE architecture implemented by ARM and Samsung in its exynos CPUs, and against fuss prevalent, SAMSUNG EXYNOS in S5 being inferior graphic performance.
Definitions:
Cluster-migration: In given stress level all four A15(most high performance ARM CPUs ever made- apple uses A7 in IP5s) are running or Quad core A7 CPUs(most power efficient ARM Cpu)
Core-migration: Any combination of 4xA7 or 4xA15, though only 4 cores at a time.(1xA7-3xA15,2xA7-2xA15,etc)
Heterogeneous multiprocessing: All 8 cores can be online at once, A7x4 + A15x4 = 8 cores
bigLITTLE architecture by incorporating the best high performance CPU ARM A15 with a power efficient A7 ARM CPU is future. The migration between the A7 CPU cluster and A15 CPU cluster is managed by a hardware chip called CCI (cache coherent interconnect) its a sort of Memory management unit which transfers the cache(running apps) between the cores. Currently EXYNOS is the only released version of this architecture as S4 i9100 and later S5. This architecture is being implemented by both Qualcomm and MediaTek in future chips.
The only issue is the abscence of LTE radio chip,but with capability of 42mbps Downlink speed at 3G its not an issue in this part of world! Samsung has included in this design a wolfson DAC and dedicated Efficient GPU which supplements the ARm A15 CPU performance and is OpenGL 3.0 compatible!
In contrast Qualcomm implementation is different. It's a Quadcore A7 architecture overclocked to 2.2ghz. The clock speed is dynamic and not fixed. Each core can run at variable speeds, hence in a given time frame not all 4 cores are at 2.2Ghz, this would kill the battery and generate excessive heat! But with comparatively weak CPU is a Powerful GPU Adreno 330.
Hence the two architectures are very different Exynos with A15 is new and Qualcomm with faithful A7 is older! Since the telecoms here are reluctant to adopt LTE in near future, and if so, the subscription rates will be very high. Releasing a phone with new gen CPU and Wolfson DAC, Open GL 3.0 compatible GPU is practical. Rather than redundant LTE version, as redundant as Apple's 64bit CPU in Iphone 5s!

Exynos 5422 is 2.1 Ghz Quad-Core A15 + 1.5 Ghz. Quad-Core A7 with HMP

Like nokia Samsung's days are now numbered in India, trying to fool people with inferior processor

kingpin, 31 Mar 2014Yeh exynos can wipe the floor with snapdragon only while it's connected to a charger... exynos... moreit doesnt even top.. samsung mostly rigs benchmarks for exynos to hide its cheap performance.. its also like plastic...

Ex y no us is the real name cuz it's by far inferior to snapdragon.
For the kids who think diferent then you can just buy the phone,cry for the money and laugh when other buy this crap.

Benchmarks are for geeks. In the real time usage it doesn't make difference

Samsung should launch snapdragon version in india.... it's better than exynos verson. It's not that exynos is bad. Coz great phones like s2 and note 2 used exynos. It's only that snapdragon uses the battery wisely. Performance wise both are almost the same.
Now to the real shit is samsung knows that some consumers in some countries believe that more cores mean more power... so they they sell crap for a price.

Anonymous, 31 Mar 2014Xperia Z2 and HTC one M8 comes with snapdragon 801 nothing special about S5 chipset. Mr. anonymous your petty attempts to steal the shine from this handset its not working because everyone knows there's a snapdragon 801 version of the galaxy s5.

Exynos is superior in every benchmark Exynos 5420 wiped the floor with S800 and this one will also wipe the floor with S801 for sure.
And for those who are making lies you should be ashamed of yourselves, Exynos always is better since S1/Note1.
Exynos 5420> Snapdragon S800:

Samsung is gonna be Shit in this year.... 2 gb ram is not enough for an octa core version.Even note 3 octa core versions lags in playing San Andreas and all games that too V can't able to keep the phone in our hands the phone gets Damn heat

Exynos is still inferior to snapdragon. Why can't samsung accept the truth and just ship all their S5 units with the 801?

Samsung y do u release this dumb exynos chipset of yours in India when nobody wants it.. Y cant u give the snapdragon variant dats international version here.. Y do u want to make people to buy again an lte enabled phone when they get 4g shortly.. Cheap buisness tactics fooling people...
