According to ABI Research vice president of engineering, James Mielke: “Samsung started from scratch with this phone; almost every component is new. Its application processor is the most powerful on the market at present. It is the first to use the Samsung Exynos 4210 dual-core application processor (a competitor to NVIDIA’s dual-core Tegra 2). The name Exynos combines Greek words for ‘smart’ and ‘green,’ indicating Samsung’s energy efficiency goals for the design.”
Major changes include: Exynos dual-core apps processor. 118.8 mm2 die size with amperage specs roughly similar to the Tegra 2; New single-packaged multi-band multi-mode PA from RFMD; New CMOS-based antenna switch; New lower-power XMM6260 cellular chipset from Infineon.
Mielke summed up: “Samsung took many risks by combining all these new technologies into one phone. But ABI Research believes those risks will pay off; the Galaxy S II sets a new benchmark for almost every category on which a smartphone is measured.”
