5.5" Huawei Glory 3X unveiled as the company's first octa-core phone

The octa-core processor is MediaTek MT6592, and, while it indeed has eight 1.7 GHz cores that can work simultaneously, they are all Cortex-A7 ones, so performance is about on par with Snapdragon 600, as far as benchmarks are concerned.
Huawei placed a generous 3000 mAh battery in the Glory 3X, which is actually right in the phablet area, and the device is a dual SIM handset, for the going rate of about 1700 yuan, which translates to USD 280. Not a bad pricing for the ability to brag you have a "true" octa-core phone to anyone who is liekly to care.
