The Raspberry Pi 3 has been released, and we've been able to get our hands on the mini-computer for a time now. Besides a built-in wifi and bluetooth-module, not much is new about about the Pi, though it does have a new processor. We took Sysbench to measure the speed of the cpu to see if it really is faster than earlier models.
The Raspberry Pi 3 is indeed more powerful than its predecessors. The third generation mini-computer has a Broadcom BCM2837-cpu, as opposed to the BCM 2836-soc in the 2 Model B+. That means the new soc has a clockspeed of 1,2 GHz, as opposed to 900 MHz in its predecessor.
RAM stays the same, at 1 GB.
We ran Sysbench on 3 different devices: The Raspberry Pi 3 against a Raspberry Pi 2 Model B+, and we threw in an original Raspberry Pi 1 for good measure.
Benchmark with Sysbench
You can see the Pi 3 is about 40% faster than its predecessor. These are the results for the Raspberry Pi 3:
