Samsung has been teasing with “Exynos Infinity” before Mobile World Congress 2014, and many expect the Korean company to announce their 64-bit mobile processor (Exynos 6 ?). But it’s likely another Exynos SoC will (also) be announced, as a quick search shows recent patch submissions for Exynos 5260, which happens to be an hexa-core processor using two ARM Cortex A15 cores @ 1.7 GHz, and four ARM Cortex A7 cores @ 1.3 Ghz in big.LITTLE configuration supporting HMP (Heterogenous Multi Processing) / GTS (Global Task Scheduling). The official name might be something like Exynos 5 Hexa (5260).
It would probably be possible to go through the patches to find out more, but there’s an easier solution, and some blogs have already posted details about a leak showing Exynos 5260 used in the upcoming Galaxy Note3 Neo, where we learn the GPU is an ARM Mali-T624. The mobile phone itself boasts a 5.5″ display @ 1280×720, 2GB RAM< 16Gb Flash, an 8MP rear camera and 2.1 MP front camera, and a 3,100 mAh battery. Reports indicate Android 4.3 is currently running on the device, but that it should be eventually be upgraded to 4.4.
The phone gets 29,3282 points in Antutu 4.x, just below Samsung Galaxy Note 3 powered by the more powerful Exynos 5 Octa 5420 or Snapdradong 800.
