# Raspberry Pi 3 Floating-point Benchmarks

By Joseph D. Gaeddert on March 31, 2016

There's been a lot of hype about the Raspberry Pi 3's performance, but how does it fare with signal processing for software-define radios? Here are some benchmarks for multi-threaded performance with liquid-dsp.

The Raspberry Pi 3. Same price, better floating (point) performance.

The Raspberry Pi Foundation released the third version of their popular development board at the end of February this month, and like a good engineer I decided to put it through the SDR wringer . Unlike my previous I did not include the Beagle Bone . Here are what the three incarnations of the Pi look like side-by-side:

Evolution of the Pi: one, two, three.

Notice a trend? That's right; the silkscreened raspberry is getting smaller. Probably to make room for more horsepower and onboard WiFi (see the tiny antenna on the top right corner of the card). While the 3 offers a CPU speed improvement of 1200 MHz over the 900 MHz of the 2, the real performance bump comes from an improved ARM architecture; from the quad-core ARM Cortex-A7 on the 2 to the quad-core ARM Cortex-A53 on the 3.
