MediaTek is certainly proving that it can go toe to toe with the big boys of the mobile processing world, as it was the first company to announce a true octo-core chip, and now the company has unveiled its first attempt at a big.LITTLE processor.
The newly announced MT8135 chip is an asymmetrical quad-core processor, in that, just like Samsung's Exynos 5 Octa, it features a combination of high and low performance CPU cores, two Cortex A15s and two Cortex A7s. But unlike the current version of the Exynos 5 Octa, all four cores can be used at once thanks to big.LITTLE MP (heterogeneous multi-processing) mode, meaning that this is a real quad-core chip.
But that's not all, MediaTek is also ramping up the performance of its new chip with some next generation graphics from PowerVR. The MT8135 will feature a PowerVR G6200 GPU, which is a generation up from the PowerVR SGX544MP3 chip found in the Exynos 5 Octa Galaxy S4.
Performance wise, the Series6 GPUs are supposedly capable of exceeding 100 gigaflops, which is almost twice that of the 544MP3, and can apparently deliver “up to four times more ALU (arithmetic logic unit) horsepower” that the older series5 XT chips.
MediaTek has also included some benchmarks for the big.LITTLE MT8135, but as these are coming straight from the developing company I'd take them with a pinch of salt. The Antutu benchmark of 23557 puts the chip just behind the Snapdragon 600 processor found in current high end chips, but this score is probably helped on by the newer GPU.
In terms of CPU performance, it won't be quite as fast as the high end quad-core processors, like the Tegra 4 or Snapdragon 600, but it should provide some significant energy savings thanks to the lower power cores. But the new GPU core could give this chip some serious grunt when it comes to gaming performance. MediaTek is aiming the chip at the “the middle to high-end tier of the tablet OEM market”, which sounds about right in terms of performance.
If you'd like a look at some of the other benchmark results, MediaTek has also released the following promotional video. Even if these benchmarks are slightly exaggerated, the MT8135 certainly looks like a promising chip for future mid-range devices.
