Samsung has announced new Dual core and Quad core CPU that will replace the current generation dual-core Exynos processors. These new CPUs would pave the way for the future smartphones in 2012 & beyond.
The Exynos Core
New Exynos chip can come in dual-core and quad-core configurations which can switch frequencies from 200 MHz to 2.0 GHz. The new Exynos CPU are fabricated with 32nm technology, which makes them way more efficient than previous generation 45nm process. What this means is that you’ll have more performance for the same clock frequency, that too at a lower power consumption.
Upcoming Exynos parts include:
- 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
Exynos 4412 would be used in Galaxy SIII (full specs).
New Exynos supports for LPDDR2 or DDR3. Samsung has moved to new Low Power DDR3 memory.
Exynos comes with a new 4-core GPU also called 4 pixel processors and 1 geometry engine with 128 KB L2 cache. With standard 3D OpenGL ES 2.0 it can generate up to 57 MPolygons/s. Good enough to play HD resolution games on smartphones, tablets.
The latest addition to the Exynos family that we have not talked much about is the quad-core Exynos 5450. This upcoming part will feature the latest ARM Mali-T658 GPU
Exynos Performance Improvements
New 2012 Exynos CPU can deliver up to 26% more performance than 2011 45nm processor with battery life improvements of upto 50%: 45% power save shown in a Samsung demo for CPU tasks, and 48% for 3D calculations.
Anyway, it looks like we’ll all enjoy quad-core performance with more battery life in a few months. Samsung claims that new Exynos are designed to deliver performance with stress on optimizing power consumption. This means future devices like Galaxy SIII would be a performance oriented, yet, very battery friendly.
Cortex-A15 is a huge improvement over Cortex-A9. We might not see TI’s OMAP5 in devices until early 2013, but Samsung has said that their Exynos 5250 will go into mass production next quarter. That would be perfect timing for it to appear this summer in Samsung’s flagship devices.
