Today Samsung announced a new mid-range SoC called the Exynos 7870. The new SKU sports 8x Cortex A53s running at up to 1.6GHz. The GPU should be an ARM Mali T830 although we have no information on core-count or frequencies used. The part extends Samsung's ModAP lineup of SoCs with integrated modems as we see an integrated UE Category 6 modem integrated, delivering up to 300Mbps with FDD-TDD joint carrier aggregation.

More interestingly, is that the new SoC is manufactured on a 14nm FinFET process which promises to reduce power consumption by over 30% over similar SoCs such as the Exynos 7580. Only a few days ago we were discussing our surprise with the introduction of Qualcomm's Snapdragon 625 which is also manufactured in a 14nm LPP process, a great sign for the manufacturing process given that these mid-range parts are very price-sensitive. Samsung discloses that the Exynos 7870 will be in mass production in the first quarter of 2016 so we're essentially very close to device availability in the following months.

Another low end chip masquerading as a mid range solution. Single channel memory again, ARMs weakest 8 series GPU and a relatively low clockspeed.. MehBurntMyBacon - Wednesday, February 17, 2016 - link
@LiverpoolFC5903: "Another low end chip masquerading as a mid range solution. Single channel memory again, ARMs weakest 8 series GPU and a relatively low clockspeed.. Meh"You mad bro?
Is it because the new so called midrange isn't up to the performance that you expected with a two node + finfet process improvement?
I'll bet it's because the new so called midrange isn't up to the performance that you expected with a two node + finfet process improvement.

The perf is less than what others offer on 28nm.Might have lower power unless their modem is power hungry. Mediatek Helio P10 goes up to 2GHz and has better GPU today on 28nm with rather good battery life.vs others going FinFet they offer a lot less perf. P20 at 2.3GHz and claimed 50% faster GPU than in the P10 while SD625 at 2GHz(maybe more) and a GPU perf that is likely to be plenty higher than here.
Samsung is wasting resources designing chips like this, they would be better off with dual A72+ some A53 on any process to boost the user experience on their midrange phones.

You nailed it. Considering the fact that the Helio X10 is clocked at 2.2ghz on a 28nm process, you would think Samsung would at least be in the same ballpark as the 7580 on an advanced 14nm finfet process.I bet the A53 can be clocked as 2.5 on a 14nm process, with little loss in efficiency.
A 2.2 -2.5ghz Cortex A53 based Octa with dual channel memory and a competent GPU would have been more like it for the upper midrange. I mean the likes of galaxy A7 and A8...
As it stands, even the Mt6752 is probably faster than this. We are talking about a 2 year old SOC that has been used in 200 USD phones.
I simply don't see any value in this chipset for midrange phones. Apart from lower manufacturing costs due to increased vertical integration, I don't see Samsung getting a lot of traction with this chipset.

To be fair the X10 is rather power hungry but the P10 on 28 HPC+ is a different matter and should have significantly better battery than even the MT6752.psychobriggsy - Wednesday, February 17, 2016 - link
I have a 7580 in my phone (S5 Neo). It's fine, the only app that struggles sometimes is Facebook, and let's be honest, Android Facebook would struggle on an octo-core A72 at 3GHz. Battery life is pretty good, and will only get better with this.Also, two mid-range 14nm designs indicates that Samsung's 14nm process is maturing.

I love that an 8-core processor running at 1.6GHz with an integrated GPU and modem etc etc is considered low-end :-)Remember when the first 1GHz CPU came out? Remember when CPUs ran at 1Mhz? I know it's different, but still... I love it!

2020: These low-end 16 core chips masquerading as the new so called midrange SUCK!thope - Wednesday, February 17, 2016 - link
Good to see sammy trying to be a chip oem. Since apple is sucking up tsmc chips. Samsung needs these smaller wins. I think I read somewhere that samsung is going to fab qualcomm chips. Hopefully this happens. missing android cpu parity with iOS.frenchy_2001 - Wednesday, February 17, 2016 - link
If the table is correct, they are.Samsung has a 14nm FF process. TSMC has a 16nm FF process, so the Snapdragon 625 is probably manufactured at Samsung...
