Samsung Unveils Exynos 5 Octa 5422 and Exynos 5 Hexa 5260 SoCs

As expected, Samsung announced the Exynos 5 Hexa 5260 hexa-core processor and, the not-quite-expected Exynos 5 Octa 5422 octa-core processor at Mobile World Congress, both of which feature ARM’s big.LITTLE processing technology, and ARM Mali-T628 GPU. Still no news about their 64-bit processor.

Exynos 5260 will feature two ARM Cortex A15 cores up to 1.7GHz, and four Cortex A7 cores up to 1.3GHz, with full support for HMP/GTS. Contrary to initial reports the new processor is not based on Mali-T624 (as shown in Antutu), but according to Samsung Exynos 5 Hexa page, it will instead use Mali-T628 just like in Exynos 5420 and 5422. This processor could end up with the best price/power consumption/peak performance combo, as few application are able to use more than 2 cores. The SoC also features an embedded Display Port (eDP) interface, and with a memory bandwidth up to 12.8GB/s, supports supports WQXGA (2560×1600) resolution. Exynos 5 Hexa’s video codec supports 1080p 60fps encoding and decoding of H.264, MPEG4, VP8, and more.

Exynos 5422 appears to be a update to Exynos 5420 octacore SoC, with four Cortex A15 core clocked at up to 2.1GHz, and four Cortex A7 cores clocked at up to 1.5GHz. The GPU is still Mali-T628, and the processor also supports HMP. One key difference with Exynos 5260 is that it supports 4K hardware video decoding, albeit outputted to a display up to WQXGA (2560 x 1600) resolution. It’s quite likely Exynos 5422 will be the processor running in the Exynos version of the Galaxy S5. Exynos 5422 page on Samsung website has with very few details at this time.
