MediaTek tries to pretend that the Exynos 5420 doesn’t exist as it launches world’s first true octa-core processor

mediatek-MT6592-graphicIn a brazen attempt to look better than its competition, MediaTek has unveiled the MT6592, a processor which it is claiming is the world’s first true octa-core mobile platform. Ignoring all the fluff in the release information like “premium gaming performance” and “perfect balance of performance and power consumption” the MT6592 does look like a rather special processor, all I object to is MediaTek’s insistence that the Samsung Exynos 5420 doesn’t exist!

The eight-core MT6592 is built using 28nm HPM manufacturing process which has allowed MediaTek to ramp up the clock to 2 GHz per core. The MT6592 features what MediaTek are calling a “world-class multimedia subsystem with a quad-core graphics engine,” which is actually just an ARM Mali-450 MP GPU clocked at 700 MHz. However, MediaTek says it can handle 4Kx2K H.264 video playback and includes support for new video codecs such as H.265 and VP9. Interestingly the SOC also features MediaTek’s ClearMotion technology that automaticaly does frame-rate conversion for 24 or 30 fps video to 60fps video for smoother playback.

The MT6592 delivers longer battery life, low-latency response times and the best possible mobile multimedia experience. Being the first to market with this advanced eight-core SOC is testament to the industry-leading position of MediaTek.

MediaTek are making a big thing of the fact that this processor has eight-cores and that the MT6592 can harness the full capabilities of all eight cores in any combination. Something which the Exynos 5420 can do as well, but MediaTek seems to have overlooked that.

For the cores MediaTek has opted to use eight Cortex-A7 cores arranged in a big.LITTLE configuration. Which doesn’t make much sense as big.LITTLE is meant to be for a true Heterogeneous Multi-Processing design where some of the cores are faster (i.e. Cortex-A15 cores) than others. It seems that MediaTek has arranged the eight cores in a kind of little.LITTLE arrangement. In this arrangement MediaTek is using its own scheduling algorithm that also monitors temperature and power consumption to ensure optimum performance at all times.

The company says we should expect devices running Android 4.2 Jelly Bean by the end of 2013 and Android 4.4 Kit-Kat based devices are expected in early 2014.

What do you think? Is the MT6592 a brilliant new design? Why does the company ignore the Exynos 5420?
