Samsung Exynos 4 Quad Core Chip Previewed; Launch Likely at MWC

February 24, 2012, By Sanjeev Ramachandran

Samsung has at last previewed some real stuff from their stables for the gamers. The much anticipated quad core chip dubbed as Exynos 4 is what we are talking about, and it is expected to power high-end smartphones and tablets from Sammy’s labs in the upcoming future.

Previewed at the recently concluded International solid-state Circuit Conference, the chip is expected to get an official launch at the imminent Mobile World Congress at Barcelona in Spain.

To talk about the specs of this new chip, there is enough stuff to drool about. It has four ARM cortex A9 cores with a maximum frequency of 1.5 GHz, a dual channel controller with support for LP-DDR2, DDR2 and DDR3 memory.

It also packs an ARM Mali GPU and a 64 bit NEON media engine. The performance is improved with a shift to the flawless 32 nm process than the earlier 45 nm chips like Exynos 4210 which is powering the Samsung Galaxy S II.

Moreover, the chips pack the legacy of using high-k materials and metal gates (HKMG), which help it leverage performance and at the same time keep battery consumption lower than its predecessors. However, it does not carry a low power companion processor to preserve battery life like its rivals like Tegra 3 from NVIDIA.

The Exynos 4 has shown 35 to 50 percent more performance than Exynos 4210. The 32 nm HKMG has helped Sammy to deliver a 40 percent better transistor performance.

We learned that Sammy packs more than one part  in the series. Among them, Exynos 4212: 32 nm, 1.2-1.5 GHz dual-core ARM Cortex-A9 CPU, ARM Mali-400 GPU, Exynos 4412: 32 nm, 1.5-1.8 GHz quad-core ARM Cortex-A9 CPU, ARM Mali-400 GPU, Exynos 5250: 32 nm, 2.0 GHz dual-core ARM Cortex-A15 CPU, ARM Mali-T604 GPU, Exynos 5450: 32/28 nm, 2.0 GHz quad-core ARM Cortex-A15 CPU, ARM Mali-T658 GPU are all supposed to add to the party with the quad core chips in Sammy’s stable soon.
