The Linpack test also measures how rapidly a machine can handle floating point calculations. The Whetstone benchmark measures another aspect of processor performance, this time how it handles floating point calculations. The Dhrystone benchmark measures the general performance of the CPU - focusing on how it handles calculations using integers. The Chip benchmark results were taken from this bit-tech review. That being said we ran some performance benchmarks to see how the Pi Zero W measures up against both its more expensive bigger brother, the Pi 3 Model B, and a competitor, the $9 Chip computer. The overall performance of the board should be pretty much unchanged from the original Pi Zero, as the Pi Zero W has identical specs to the earlier board. My measurements put the energy consumption lower than that of the original Pi Zero, but that could just be down to the use of different equipment to measure the power draw. Here you can see the draw for the Pi computers when idle and when downloading a file with around 100% CPU load. That said these figures are not meant to be absolute measures, since network speed can be affected by so many local factors, but an indication of relative performance.Īnother key metric for those building a battery-powered device around the Pi is power consumption. This iPerf benchmark measures the speed of data transfer between two computers, in this case between an Ethernet-wired Ubuntu laptop and a Wi-Fi-connected Pi 3, Pi Zero W and Ethernet-linked Pi 1.
#LINPACK BENCHMARK CNET BLUETOOTH#
On paper, you might expect little difference between the Pi 3 and the Pi Zero W, as they both support 802.11b/g/n Wi-Fi and Bluetooth 4.0 and use the same Broadcom wireless chip, however that wasn't the case in practice. SEE: Raspberry Pi in 2017: New boards, new OSes and moreįirst, let's take a look at how the built-in Wi-Fi performs compared to the Pi 3 and the Ethernet performance of a Pi 1. We set out to measure how the board performs, starting with the new features like network performance and how Wi-Fi support affects power consumption. You can read our guide to everything you need to know about the Pi Zero W.
#LINPACK BENCHMARK CNET PLUS#
By adding Wi-Fi and Bluetooth connectivity to the Pi Zero, a fun and incredibly cheap board has become far more useful out of the box, albeit at a slightly higher price of £9.60 ($10 plus tax).
