Samsung announces the Exynos 5430, its first 20nm SoC

The Exynos 5430 processor has four ARM Cortex A15 cores clocked at 1.8GHz and four Cortex A7 cores clocked at 1.3GHz. But the real news is that it's Samsung's first SoC built on the new 20nm process.

Samsung's latest SoC (system-on-a-chip) was revealed yesterday when the South Korean technology giant announced its Galaxy Alpha smartphone. But how powerful exactly is the new Exynos 5430 SoC? Thankfully, Samsung has provided details of its new processor.

For starters, the Exynos 5 Octa (5430) processor has four ARM Cortex A15 cores clocked at 1.8GHz and four Cortex A7 cores clocked at 1.3GHz. But the real news is that the 5430 is Samsung's first SoC built on the new 20nm process which consumes lesser power without affecting performance.

According to Samsung, its 20nm HKMG performs 30 percent better than the 20nm technology because of its gate-last approach. Specifically, the chip's gate is now located at the last part of the transistor, minimizing the effects of high temperatures.  

Samsung's 20nm HKMG also uses ultra-low k dielectrics to lower power dissipation. Simply put, Samsung's 20nm HMP (Heterogeneous Multi-Processing) is a giant leap from the previous 28nm HKMG.

What's more, the new Exynos 5430 uses ARM's big.LITTLE processing technology, allowing eight cores to run at the same time. Other promising features of 5430  are support for LTE Advance Category 6 and sharper digital images, all thanks to Samsung's ISOCELL CMOS Image Sensor.

We'll learn more about the chip in our upcoming product reviews. Samsung's soon-to-be-announced flagship devices, namely, the Galaxy Note 4 and the Galaxy S6, will most likely utilize the chip.
