Claudiu.Lucian, 29 May 2017Custom cores ? What are you talking about? Kryo 260/280 and Mangoose M2 are nothing more than ... moreDo you have a reliable source that M2 is A73 based? As far I am aware, it is not a Built on Cortex licensed product, hence it is not based on ARM cores. If they're using ARM designs without doing the BoC license, it is just a lawsuit waiting to happen. You know how much Samsung loves to be embargoed.

Claudiu.Lucian, 29 May 2017Haha, actually, I don't like Chinese phone companies. I say facts, just look at last year's Hu... moreIn my opinion A72 is a little better than A73. But less efficient...
I know geekbench says the opposite, but that's not the only benchmark that says opposite than reality.
Decoding performances seems to be better on A72 for exemple...
A72 pipeline is 3 instructions wide (3 instructions per clock frequencie), A73 is only 2. It leads to less heating and less consumption...
Silicone area is smaller too, si A73 is cheaper than A72
Arm does a very good job, A73 is really close to A72 despite smaller pipeline
With A75, Arm takes the A73 improvements and restore 3 instructions per clock...A75 is OK due to 10nm
I think Kryo 280 is a kind of A73...
But Kryo 260 isn't a A72...
I think it's a kind of A73 too, 2 instructions wide too... But maybe with shorter pipeline.
Huawei acheive a good Kirin 950...it is often faster than s820 and sustains performances far better.
The great thing with this new A75/A55 cores isn't the cores themselves, it's their management : DynamIQ...
API like Vulkan will need soc that were able to sustain GPU and CPU charge at the same time...
We will see the limits of crappy bench like Antutu which tests CPU and GPU separately...thermal enveloppe will be very important so that 2+6 would behave better than 4+4
Apple has a great advantage with their Giant cores, the best Arm cores since A7...but they should developpe core management. Now they were able use 2 or 2, not even 2+2

Tsuki, 29 May 2017What do you even do with phones! Even with charge n play all my phones have original batteries. Indeed he is wrong. The point of replaceable batteries is to get instant 100% charge (huge for frequent fliers like me and generally for people that commute and don't want to mess with mobile chargers)

ziana zain, 29 May 2017in your dreams,huawey fanboysHaha, actually, I don't like Chinese phone companies. I say facts, just look at last year's Huawei Mate 9, doesn't it have A73 cores and it was released in November?

Kryo 260/280 and Mangoose M2 are nothing more than A73 cores(Kryo 260 is A72) with small changes just to name it different (same performance per clock, similar power consumption). The whole market is already based on stock ARM cores. (not talking of Apple , which is a market itself)

Qualcomm was unable to use properly nor 64bits, nor octacore...410, 615, 810, 808 were bad too!
Mt6752 was nearly 40% faster than 615 in real use...615 can't even be as fast as quad core 6732!
But that's Qualcomm, they sell even when they're bad.
They improve a lot, 625 behaves quite good now, nearly as well as 820...(I talk about real use, not benchmarks)
Helio P20 too
https://youtu.be/VvyCQmNInzk
Even P10 with old 28nm process behaves well
https://youtu.be/HNXHm6f4Tmc
OK iPhone 7 is faster, but not that much, remember too, that's only midrange that costs 200 bucks...from unknow Companies.
Real difference is only on loading games
Octacore is a good way to do cheap but efficient soc.
Don't forget too, that Apple use a kind of cluster migration on A10...that's the worst big.LITTLE implementation
That's why, A10 is sometime slower than A9
With newest DynamIQ cores management, I think de will get very good 2big+6LITTLE

Sam Boga, 29 May 2017So is this still 14 nm?YOu can use which ever size you want, there are A53 cores at 28nm as well as 14nm

Anonymous, 29 May 2017And Android has more battery life with 8 Core lelBecause android phones are in general fatter and bigger so they have more space for a bigger battery, and those 8 cores are tiny so they save energy but take a much longer time to load so the only thing they do in conclusion is to waste your time while you get the same work done in a longer time at same battery endurance
Lel
And now take your low end SD615 8core phone and go crying in the corner

PRNS, 29 May 2017that bar so confuse me, 1.24x same as 24% but seem like 240% Exactly. ARM using deceptive graphics (not having the bars start at point zero) must be called out for it.

With this improvements, custom cores will need significant improvement to compete with ARM standards. Or else, next gen SoC is a matter of configuring big and LITTLE cores within and between clusters (over 3000 possible configurations if I'm not mistaken?).

Qwerty2017, 29 May 2017Nope, it's almost ZERO percent ANY phone manufacturers will use a SoC with Cortex A75 for thei... moreI think A55 won't be in tandem with A73.
Because A73 isn't compatible with new DynamIQ...but only old big.LITTLE. the main avantage between A55 and A53 is DynamIQ...it will be bad to kill it with incompatible A73!
So that, in my opinion instead of building 4big A73+ 4LITTLE A55, 2big A75+6 LITTLE A55 with DynamIQ will be faster and cheaper
Classic big.LITTLE will be dead...you will find more and more "assymetric" clusters.
Mediatek already start to make their own for a year with Corepilot...
Corepilot was a more flexible core arrangement with a coherent cache.
Corepilot will die too, due to DynamIQ

Five Star, 29 May 2017First phone with this new tech will be the Kirin 970 which will be included in the Huawei Mate 10Nope 970 has been confirm using New Generation A73.. The diff between 970 Vs 960
1) New Gen A73
2) New Gen Heimdal GPU
3) 10nm FinFET

Qwerty2017, 29 May 2017Nope, it's almost ZERO percent ANY phone manufacturers will use a SoC with Cortex A75 for thei... moreThe whole point of DynamIQ is to allow more flexible designs hence ARM is pushing for chip designers to include one (or two) A75 core even on budget chips. The die area is roughly the same as going all A55 so production costs should be similar but performance will be improved significantly. It might increase the royalty costs a bit but they will definitely use this to separate entry level from budget. DynamIQ is not compatible with older cores and this is the direction ARM designs are going. I can't see a Qualcomm 630 successor not doing a 7 x A55 + 1 x A75. The payoff will make it happen.
In fact I will predict that DynamIQ will make re-hashing their old designs and trickling them down obsolete. The only thing preventing that might be R&D costs but they have to bite the bullet sooner or later. If not next year, then the year after.
Of course if chip designers continue to stick with big.LITTLE then they can continue to pump out old designs to their heart's content but it seems a futile gesture considering how much flexibility they gain from shifting their design paradigm and ultimately it'll improve their performance, their efficiency and their costs.

Loki, 29 May 2017Mediatek should use 10 nm tmsc and make eight core like hisilicon kirinArm explains what DynamIQ is...the successor of Big.LITTLE
They says that 1A75+7A55 is a good solution on term of performances, sustain power and silicone area (=Price)
They put an additional cache to linked clusters...
Oh wait, Mediatek put 2A73+4A53+4A35 on X30 in 10nm with Corepilot 4.0 and Coherent Cache technologie
(Already use corepilot 3.0 with 2A72+4A53+4A53 on X20 serie...quite good CPU performances if you test it for real!)
Mediatek already use something that is close to DynamIQ and you want that they came back to an old 4+4 big.LITTLE?
Problem of X serie is more probably Qualcomm's CDMA/lte patents fee
