MediaTek today announced the worlds first true octa-core processor in which all eight cores can work simultaneously. The MT8135 is based on ARMs big.LITTLE architecture and has four Cortex A7 cores and four Cortex A15 cores. Just like Samsungs Exynos 5 Octa SoC, the A7 cores are utilized for most low-intensity tasks while the A15 cores kick in for the heavy lifting. However, unlike Samsungs implementation where only one set of four cores (A7 or A15) can be active at any given point of time, MediaTek has implemented what it calls heterogeneous processing where applications will have access to run all eight cores simultaneously, claiming the MT8135 to be the worlds first true octa-core processor.
The MT8135 features a MediaTek-developed four-in-one connectivity combination that includes Wi-Fi, Bluetooth 4.0, GPS and FM and it also supports Wi-Fi certified Miracast. It also has PowerVR series 6 GPU from Imagination Technology. MediaTek is also rumored to be working on another chipset, the MT6592, that has eight A7 cores clocked at 2GHz each. Details of the chipset were leaked earlier this month but MediaTek is yet to officially announce it.
The benefits of ARMs big.LITTLE architecture are yet to be seen. Samsung, which had first implemented it in its Exynos 5 Octa chipset didnt perform well, and has now announced a new version that claims to have better power and processing performance.Google+
