Samsung may announce the Galaxy S7 as soon as January 2016, but the company cold start producing some of the smartphone’s parts even sooner. A new report claims mass production on the new M1 chip is set to kick off by December at the latest.

Citing anonymous industry sources, Business Korea also claims the processor, known internally as the Exynos 8890, will be company’s first to feature a custom-designed core. That should mean an even smoother and more stable experience in the Galaxy S7, assuming Samsung can optimize the new hardware for Google’s Android operating system.

Samsung is also allegedly working on optimizing Qualcomm’s upcoming Snapdragon 820. The company is expected to offer the Galaxy S7 with its own chip in Korea and Europe, while the U.S. and China will get a Snapdragon-powered version. A third variant running an Exynos 7 series processor may also launch in India.

We still don’t know much about the Galaxy S7, though rumors are already pouring in. According to one report the device will only be available with a curved-edge display, and will come in 5.2 and 5.7-inch size options. The device may also feature a USB-C charging port and a tougher magnesium alloy design.

Sounds like a pretty sweet smartphone, though we won’t know for sure until Samsung actually unveils the Galaxy S7.
