At Samsung's Mobile World Congress press event, they didn't reveal the technical details of any of their new processors in development, but this morning they did. Samsung officially outed their Exynos 5422 Octa-Core CPU and their Exynos 5260 Hexa-Core CPU. The Exynos 5422 is primarily slated to show up in version of the Galaxy S5 designed for areas where there are little to know LTE markets. Using four ARM Cortex-A15 cores clocked at 2.1 GHz alongside four ARM Cortex-A7 cores clocked at 1.5 GHz, the 5422 will deliver 34% higher performance than their previous offerings.
The Exynos 5260 Hexa-Core processor is already showing up in their upcoming Galaxy Note 3 Neo. This 6-core design will use two ARM Cortex-A15 cores clocked at 1.7 GHz matched up four ARM Cortex-A7 cores running at 1.3 GHz. The A15s are responsible for performance, and the A7s are only for when you’re not doing any CPU-intensive tasks on the device. This is another example of ARM’s big.LITTLE designs, although this is the first time we have seen a 2+4 combination.
Samsung teased their Exynos Infinity chipset, yet have not given any other peeps regarding it during MWC. Perhaps they are waiting for a different time/place to share the details. Most of the industry speculation believes it will be their new 64-bit chip designed to "compete" with Apple. We'll let you know when we find out more.
