The new 2GB LPDDR3 DRAM can transfer data at up to 1600 megabits per second (Mbps) per pin, which is approximately 50 percent faster than a LPDDR2 DRAM.
Samsung started mass production of the industry's most advanced mobile DRAM (dynamic random access memory) chip, only 10 months after it began producing the industry's first 30nm-class based 2GB LPDDR2 memory in October, 2011.
As for the 200, you'll get quad ARM Cortex-A5 CPUs at up to 1.4GHz per core, an Adreno 203 GPU, HD video playback, GPS, LPDDR2 RAM, multi-SIM support and the ability to handle up to 8 megapixel camera sensors.
