Finally the rumored Samsung Galaxy Alpha is available for sale. The Galaxy Alpha is the first Samsung metal phone which features a 4.7inch 720p super AMOLED display, 12 megapixel camera, 2K video recording and 2GB RAM. Nowadays smartphones come with a 3000mAh to 2500mAh battery but this phone has only 1860mAh battery. Yes it’s a pretty small battery compared to the midrange specs it has, but Samsung claims it doesn’t need a bigger battery because it’s powered by their latest SoC called Exynos 5430.
The Exynos 5430 is the first Samsung 20nm SoC and Samsung claims it’s 25% more power efficient than its predecessor
Samsung Exynos 5430 is a big.LITTLE octa core processor which is manufactured under 20nm technology which means it has four big Cortex A15 cores clocked at 1.8GHz and four small Cortex A7 cores clocked at 1.3GHz. The Exynos 5430 is the first Samsung 20nm SoC and Samsung claims it’s 25% more power efficient than its predecessor Exynos 5420 which was manufactured under 28nm. Anandtech mentioned the use of the 20nm process a “significant leap forward” compared to the previous generation.
Exynos 5430 has a Mali-T628 MP6 (six GPU cores) which is the same GPU Exynos 5420 (at 533MHz) had but now it’s clocked at 600MHz. This SoC has a dedicated H.265 hardware decoder and a dedicated Cortex A5 core to handle audio and voice recognition tasks. Samsung Galaxy Alpha smartphone is still new so neither battery benchmarks nor battery reviews are out there yet. When they are available we can determine exactly how this new processor works with less power.
