MediaTek launches world’s first true octa-core mobile chip, first devices due end of year

Qualcomm's nightmare has finally come true. Earlier today, MediaTek officially introduced the world's first true octa-core mobile processor, MT6592, and the first devices to feature it are expected to arrive as soon as end of year. This 28nm chip packs eight low-power Cortex-A7 cores, and courtesy of the Heterogeneous Multi-Processing use model on top of ARM's big.LITTLE architecture, all eight cores can operate simultaneously -- at up to between 1.7GHz and 2GHz, depending on the bin.

MediaTek pointed that Chrome can already make use of all eight cores, and likewise with some map apps, video players plus multi-window function. According to the company's figures, the MT6592 manages to beat what appears to be the quad-core Snapdragon 800 in benchmarks, power consumption (as low as 40 percent) and temperature.

Samsung’s Exynos 5 Octa CPUs will be able to use all eight cores at once in Q4

Samsung's Exynos 5 Octa CPUs will be able to use all eight cores at once in Q4

We'll have to change our terminology for Samsung's Exynos 5 Octa mobile chips now. We've been calling them "not-quite" eight core CPUs since they can't actually use all eight at once, but the company's new Heterogeneous Multi-Processing solution is going to change that. Once it's available in Q4 it will let devices access both sides of the big.LITTLE ARM configuration simultaneously, which it claims will increase both performance and efficiency. While software threads with high priority use the "big" A15 core, lower priority tasks can run on the "small" A7 without needing to switch back and forth. Samsung isn't the only one running this setup however, as MediaTek announced an implementation for its MT8135 back in July. There are more details included in the press release (after the break) but we're not seeing any confirmation if this will ever be enabled on existing / announced devices like some flavors of the Galaxy S 4 or the Meizu MX3. Either way, the folks at Qualcomm might want to put together another video.
