With the objective of making it more like a general PC, the Raspberry Pi 2 has been released equipped with a 900MHz quad-core ARM Cortex-A78 processor and 1GB of RAM. It’s a considerable upgrade from the ARMv1 processor and 128MB of RAM that came installed in the first Raspberry Pi.
RSP 2 was built to run NEON-enabled multicore codecs more than 20 times faster than the original board. According to the Raspberry Pi Foundation, in single-threaded code it runs twice as fast; four times as fast as RSP 1 in Sunspider, and six times faster in multi-threaded code.
Further, its ARM v7 CPU has allowed RSP 2 to operate in a Windows environment. The foundation states that they have been working with Microsoft since last year, and now Windows 10 is available for RSP users. The ARM v7 core also makes RSP 2 compatible with Ubuntu; and a Snappy Ubuntu Core image is available.
Since the release of the first Raspberry Pi in 2012, 4.5 million Raspberry Pis have been sold. The first Raspberry Pi had a single-core ARMv1 processor with 128MB of RAM. It’s by virtue of replacing the Broadcom BCM2835 system on chip single core processor with a BCM2836 quad core processor that the RSP 2 processing power has been significantly increased.
With all its upgrades and increases, nonetheless, the Raspberry Pi 2 sells for the same low price of $35.
