Anonymous, 19 Feb 2017Tegra x1 in pixel c or nvidia shield tv has 1 teraflop and ... moreNvidia Tegra X1 is producing 512 GFLOPS in single precision.
Nvidia Titan X is producing 11000 GFLOPS (11 TFLOPS) in single precision.
But non of them are smartphone/phablet GPU. X1 is for tablets.

regs, 19 Feb 2017Quite poor Q&A. Last answer is completely and entirely ... moreTegra x1 in pixel c or nvidia shield tv has 1 teraflop and its graphical performance is as of adreno 530 in snapdragon 820. You comparision shows nothing.

regs, 19 Feb 2017Quite poor Q&A. Last answer is completely and entirely ... moreVery well said, rn3 user myself.. Sd650 is a thing of beauty, nobody talks about gflops in the mobile realm though, SOCs are much more than just floating point operations when it comes user experience. I wonder why antutu has so much popularity while the better androidbench from the cpubench people never gets a mention..

Anonymous, 19 Feb 2017Comparing cpus by single core speed is stupid. Benchmarks ... moreiOS isn't optimized for less cores. iOS doesn't have that full multitasking like Android. You do can have two apps running side by side. But minimized app gets suspended (paused), yet in Android it keeps working unless there is a low available RAM, then it gets cached or completely killed. On the one hand full multitasking is good, especially for desktops and for apps that has to do something while you work in other app and puts in into standby mode. Like when you download something, track something. On the other hand there are lot of unprofessional developers that makes own resident running services, which doing nothing that you need, yet consumes a lot of energy or even preventing device to go into sleep mode. Wakelocks is quite a major problem for Android.

Layman explanation for A10 chip will be like this, when a chip is made, according to the size and the way it's made mostly determines the performance (single thread, multi thread) the A10 chip is the biggest of them all probably twice the size (sure apple user can afford more of them costly raw materials used to manufacture the chip).. And it has fewer cores targeted towards single core performance boost. End of the day, processor performance has gone well beyond what easily an average human can recognize from using same app on both platform. While apple a10 fusion is the chip to beat, other chips does quiet well for half it's size..

Quite poor Q&A. Last answer is completely and entirely misleading.
Kirin 655 has Mali-T830MP2 running at 900 MHz and capable to produce 41 GFLOPS.
Helio X10 has PowerVR G6200 running at 700 MHz and capable to produce 90 GFLOPS.
Helio X20 has Mali-T880MP4 running at 780 MHz and capable to produce 105 GFLOPS.
Snapdragon 430 has Adreno 505 (48-core@450 MHz) that is capable to produce 48 GFLOPS.
Snapdragon 625 has Adreno 506 (96-core@650 MHz) that is capable to produce 130 GFLOPS.
Snapdragon 650 has Adreno 510 (128-core@600 MHz) that is capable to produce 180 GFLOPS.
Answer is completely misleading saying Kirin 655 and SD 650 can do all the same when SD 650 is over 4 times as powerful as Kirin 655 GPU.
Of course you can't compare different architecture directly PowerVR to Adreno to Mali. There are more important things than just operations per second. But that's +/- some percents.
Still Kirin 655 and SD 430 are not just not capable for gaming, but also unable to produce smooth UI at high resolutions.
And SD 650 is the most powerful of all them without doubt. Yes, it made with 28-nm process, so consumes nearly 2,5 times more energy than Adreno 506, but it also more powerful.
Still, if you want intensive gaming you better go with something with over 250 GFLOPS. Modern top range device are capable to produce over 350 GFLOPS. 3D usually being optimized for top range devices.

Apple is an expert in proper computers and software. Its surely a piece of cake for them to design a powerful mobile processor and os. They also brought about good cameras and high fps to mobiles. Who knows they may have had ibm help them too. Those companies are not a joke. On the other hand samsung has played well and brought massive innovation with bringing in oled high res screens and lately great cameras and good processors too. Samsung is the new leader in the mobile world where nokia, sony and apple had their time in bringing something special.

Comparing cpus by single core speed is stupid. Benchmarks themselves are stupid. Ios is optimized for less cores, android is optimized for more. Benchmarks for android should use all cores. If they use 2 or 4, then they are clearly not capable of actual benchmarking. Who even thought of the single core comparision? Probably apple fans themselves when they didnt want their devices to look inferior to android ones. The new apple chip couldn't come close to sd820, helio x20/25 or kirin 960 if there was a real benchmark without any kind of bias towards any side. More cores means more tasks can be done at the same time and also by spreading the workload across them the task can be done much faster.

"That said, there’s no doubt that the A10 is a beast of a chipset with beastly single-core performance. Part of the reason is that it only has two high-power cores with each of those much larger footprint than the Snapdragon and Kirin CPU cores. There’s also more to performance than just the architecture – stuff like L2 and L3 cache size and memory speed, which isn’t normally officially announced by manufacturers so we don’t have the full picture."
GSMArena nailed it. Note this down, spec sheet fanboys.

When did Lenovo will upload their full list of smartphone devices that will get nougat update?
