Mid-range Samsung Exynos 7872 chipset is being prepped?
From China today comes word that Samsung is working on a new mid-range chipset named the Samsung Exynos 7872. The SoC carries a hexa-core CPU with two energy sipping Cortex-A53 cores and two power guzzling high performance Cortex-A73 cores. The Exynos 7872 will be built using Samsung’s 14nm LPP (Low Power Plus) fabrication technology. This reduces the size of the die allowing for a more power efficient chip that doesn't get too hot (we're looking at you, Snapdragon 810).
 
The Mali-T830 MP2 GPU will be on board, and an integrated modem will be part of the chipset which should improve connectivity and reduce power usage. Overall, the new chipset improves CPU performance by 70 % compared to the previous line of Exynos chips built using the 28nm process. The new SoC will be 30% more energy efficient.

The Exynos 7872 could be released this coming October. We could see them inside the Samsung Galaxy A or Samsung Galaxy C series that would be released around the same time, later this year.

Wonder how this will compare to the SD mids?

Disappointingly (hopefully the rumor is wrong)

CPU wise they are pretty similar. The 660 is 4xA73+4xA53, the 7872 is supposedly 2xA73+4xA53

However in terms of GPU, the Exynos 7880's Mali-T830 MP3 is already weaker than the 28nm 652's Adreno 510. This rumor is Mali-T830 MP2 like the Exynos 7870 from last year

Exynos 7880 was just released at the beginning of the year. Confusingly, this 7872 would have a better CPU as the 7880 is all A53s

Also the 660's X12 LTE modem is Cat 12 down and Cat 13 up (on par with the 821 and 8890). This 7872 probably has the 7880's LTE Cat 7 modem

Yeah, such a lame GPU for the CPU cores, even if it's a budget SoC. Let's hope Samsung change the final specs for it, I remember the 7880 originally announced on the 28nm process, but when it finally launched this year it was on 14nm.

I'm not sure if the 7872 is supposed to be compared to the 660. I think Samsung will use this in the next A5 and they could use the Exynos 7420 in the A7 or higher. I only say that because it's being labelled as midrange, whereas the SD 660 is upper midrange. A you say though, the GPU doesn't sound good. They should start making their own.

They dont need to make their own GPUs
They just need to stop cheaping out on GPU and modem in their non flagship SoCs

Using a newer Mali-G51 MP4 would probably give them competitive GPU perf to the 660

Cost wise this is basically a Snapdragon 625/626/630 competitor. Maybe even cheaper.

"The SoC carries a hexa-core CPU with two energy sipping Cortex-A53 cores and two power guzzling high performance Cortex-A73 cores."

Err... what about cores 4 and 5?

Sorry.. i mean what about cores 5 and 6? I thought it is a hexacore soc.

"hexa-core CPU with two energy sipping Cortex-A53 cores and two power guzzling high performance Cortex-A73 cores" you are short 2 cores.

Per another site:
The new chip said to be called the Exynos 7872 is built using the 14nm FinFET process and belongs to the Exynos 7 Octa series. The processor will have six-cores: four cortex-A53 cores for power efficiency and two cortex-A73 cores for performance

So this is basically going to be competing against the new Snapdragon 660. It will be interesting to see what devices this goes on.

Correct the cores count mistake, Alan... It's been a already pointed out by the above comments.

Why does Samsung number this hexa-core SoC 7872, meanwhile octa-core SoCs like the ones in the 2017 A series is numbered 7870.

A weaker SoC getting a higher numbering...

7870 doesn't have any A-73 cores, the 7872 probably performs about the same in multithreaded tasks but will do better in single threaded tasks.

With two A73s this is more powerful than the 7870, and the number is lower than the 7880 which had an extra GPU core so I think it's all fair.

There really was no need to bring up the S810 in this article. There was literally no link, seemed unnecessary.
On another note, they should've put an extra GPU core or two in there.

Hopefully it has a good GPU.
