Samsung has unveiled only two Exynos 5 chipsets so far – the 5250 Dual in the Nexus 10 and the 5410 Octa in some variants of the Galaxy S4 – but there seems to be a third one in development, the Exynos 5210. To spice things up, there’s a rumor going around that this will be the chipset used in the Galaxy S4 mini.
Linux dev tools were committed to Free-electrons.com for a smdk5210 development kit. The model number also appears in an AOSP port on GitHub where “Exynos 5210” is mentioned by name.
The Samsung Exynos naming scheme marks the generation with the first digit and the number of cores with the second.
So the Exynos 5210 is in the same generation as the two Cortex-A15 based chipsets and is a dual-core model. Note that the Exynos 5 Octa is marked 5410, but uses ARM’s big.LITTLE architecture and has four Cortex-A15s and four Cortex-A7s with only one group of four works at the same time.
It’s unclear if the 5210 will be a big.LITTLE with four physical CPU cores that work as a dual-core processor (switching between a fast dual-core and an energy efficient one) or just pack to A15s like the 5250. The GPU is also unknown, for this generation Samsung has used both Mali and PowerVR, so it’s anyone’s guess.
Naturally, the rumor mill linked the Exynos 5210 and the Samsung Galaxy S4 mini. So far we know that it will have a 4.3” qHD Super AMOLED screen and run Android 4.2.2 on a dual-core 1.6GHz processor – the same clockspeed as the Cortex-A15s in the I9500 Galaxy S4, the A7s run at 1.2GHz.
Keep in mind that there will be an LTE version of the Galaxy S4 mini, which might switch to Snapdragon, like the I9505 Galaxy S4.
