There are rumors that Samsung is going to be building a new SoC for its high-end smartphone and tablet devices based on a new ARM chipset design. Named the "big.LITTLE", it will feature eight cores, four of which run at 1.8GHz geared for performance with the other four running only at 1.2 GHz for power efficiency. Based on ARM's Cortex-A15 core architecture, the design is taking queues from NVIDIA's Tegra 3 chipset with its '"4-PLUS-1 Quad-Core with a 5th Battery Saver Core" design. The basic idea of the design is it allows for variable switching between performance and power saving cores. The Samsung variant is rumored to follow the same design and be built upon a 28nm manufacturing process. With rumors looming of the new Samsung Galaxy S4 coming next year, it's very likely we'll hear more about Samsung and this supposed chipset.
