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.

Not happy, would prefer 1x A72 & 2x A53.Yes its cheaper, but 8x 1.6GHz is just useless in most use cases.

The problem is not the use of 8 A53 cores. The clock speed, gpu and single channel RAM are the aspects that make this a shitty soc for the midrange. elilmoe - Wednesday, February 17, 2016 - link
Andrei, I know you already got your hands on a GS7 sample (don't deny). Probably even both Snapdragon and Exynos variants. Any chance for an early overview at least?phoenix_rizzen - Wednesday, February 17, 2016 - link
If, and that's a very big IF, he has a device, the number of NDAs and press embargoes that came along with it wouldn't let anyone say anything about it until after the official unveiling by Samsung.Andrei Frumusanu - Wednesday, February 17, 2016 - link
Sorry to disappoint but no I don't have any device yet. Although I'm looking to try to get both variants if possible...lilmoe - Friday, February 19, 2016 - link
Thanks for replying. Would also be nice if you can get your hands on an LG G5 and put all three for an in-depth comparison. Would be interesting to see how different kernel implementations/governers affect efficiency of the same chip (SD820, which doesn't support big.LITTLE), and how both Samsung and LG's SD820s compare to the Exynos (and big.LITTLE).I believe it's an opportunity since it's the first time a Snapdragon and an Exynos are built on the same process.

This SoC from samsung is comparable to Qualcomm Snapdragon 650 in terms of gaming performance thanks to great software optimization done by samsung in its phones. Also thermal performance is better hence the SoC runs cooler when stressed for longer periods. It might be lacking some capabilities but OEMs never utilize all of them in mid-range devices.
