The MediaTek Helio X25 was supposed to be exclusive to Meizu, but results spotted in GFXBench show it's used by the LeTV LeEco Le 2 too (it may seem like a meme-y name, but the LeEco brand is actually pretty big in China).
The phone is a 5.5" phablet with a 1080p screen, according to the benchmark. It has 3GB of RAM and 32GB storage and runs Android 6.0 Marshmallow.
The chipset, in case you are not familiar, has a 10-core ('deca-core') CPU design - a big Cortex-A72 (2x) cluster, medium A53 cluster (4x) and a small A53 cluster (4x) each at different clock speeds (the A72s top out at 2GHz). A Mali-T880 GPU handles the graphics - same GPU as the Exynos 8890, but with a third of the cores.
The LeTV Le 2 boasts a 16MP camera with 4K video capture, plus an 8MP/1080p selfie camera. The phone should bring 4G LTE and dual-SIM connectivity, plus a USB Type-C port.
LeEco has scheduled an event for April 20, so it could be about a month before the phone is made official.
Thanks for the tip, Teja!
