velu Posted July 8, 2014 Posted July 8, 2014 Everyone in Germany who buys a Galaxy S5 in July gets a Galaxy Tab 3 7.0 for free very good deal.. hope similar deal comes to india..
velu Posted July 8, 2014 Posted July 8, 2014 finally i found the reason why A7 processor with 1.4GHZ performs as good as SC800 or Exynos 5422.. reason is very very simple.. A7 processor can execute 6 instructions in a single clock cycle ( IPCs ).. Snapdragon can execute only 3 instructions in a single clock cycle and exynos 2 or 3 ( some sites gave 3 IPCs and some other gave 2 IPCs ) having more cores is good but overrated in a real time scenario .. A7 has got 2 cores , SC 4 and exynos has got 8

velu Posted July 8, 2014 Posted July 8, 2014 Yes but still less efficient than current gen sd...it's not all perfect Iphone 5 lasts longer than 5s kya perfect hain .. if its not perfect then phone wont boot up :giggle: wat about exynos :giggle: i did lots of googling .. SD 808 and 810 will have 6 and 8 cores ,just like exynos and uses 20nm to exynos's 28nm.. i really really dont think we need more than 8 cores .. would be funny if samsung eleases one with 10 cores just for record :cantstop:

velu Posted July 8, 2014 Posted July 8, 2014 If they are real it will be good but exynos is two quad core chips in one It's not really octa and I am talking about sd and u jump to exynos :giggle: A7 has big efficiency problem just ask any iPhone 5s user ...even on my ipad with 10000 mah I think it only lasts as long as nexus 7 ... i think A7 consumes 30% more power than A6.. but iPhone 5 and iPhone 5S got almost same battery .. arnd 1500 mah.. with bigger phones they can give 2400 mah in iPhone 6 easily .. also A8 uses 20nm instead of 28 nm of A7 n A6
Old guy Posted July 8, 2014 Posted July 8, 2014 i think A7 consumes 30% more power than A6.. but iPhone 5 and iPhone 5S got almost same battery .. arnd 1500 mah.. with bigger phones they can give 2400 mah in iPhone 6 easily .. also A8 uses 20nm instead of 28 nm of A7 n A6 almost same battery is wrong in real world on recent trip my sister's iphone 5 with almsot similar usage lasted for 2-3 hours longer compared to 5s of cousin .. also iphone 6 will be thin they do not care about battery but looks
velu Posted July 8, 2014 Posted July 8, 2014 almost same battery is wrong in real world on recent trip my sister's iphone 5 with almsot similar usage lasted for 2-3 hours longer compared to 5s of cousin .. also iphone 6 will be thin they do not care about battery but looks i meant capacity .. iPhone 5 has 1450 mah and iPhone 5S has got 1550 mah .. :two_thumbs_up: so with hungry A7 it will drain the battery earlier .. anyway size of iPhone 5 and 5S is same .. cant fit a huge battery
moniker Posted July 8, 2014 Posted July 8, 2014 http://www.ebay.in/itm/like/brand-new-original-sealed-sony-xperia-sp-smartphone-white-color-/321410962773?pt=in_mobile_phones Xperia SP under 15k now :(( I have this mobile, it's the best mid range. It's on par with Nexus 4 and S3. average camera though. Still it's 20k in shops I guess. Newer sony mobiles have accidental warranty, i think this one doesn't. also it has 4.3. 4.4 is under investigation :(( That seller is only offering seller warranty. That's why price is less. I'd say never order from ebay unless you are offered manufacturer's warranty. For around 15k LG L90 is a good alternative to moto g. It has the same chipset but has a better camera and comes with expandable memory.

What about branch prediction? Once you get the answers to these questions you will have a better idea rather than just looking at it simply by instructions per clock.
Holysmoke Posted July 9, 2014 Posted July 9, 2014 iOS is like germany and android is like brazil.. iOS is more optimized. Android is more open. A better analogy would be a dictatorship vs a democracy.

What about branch prediction? Once you get the answers to these questions you will have a better idea rather than just looking at it simply by instructions per clock. and you need programs capable of exploiting that parallelism
Holysmoke Posted July 9, 2014 Posted July 9, 2014 and you need programs capable of exploiting that parallelism That's not an issue. As far as I know, the compiler does it...

Still its not clear for me how A7 performs as good as other SoCs clocked double of its freq and had hot twice the number of cores Also its surprising that apple was using Samsung hummingbird chips even for iPhone 3gs Sent from my Nexus 4 using Tapatalk
