Orange Pi Zero Plus2 H5: First impressions

29-10-2020 - 14 minutes, 22 seconds -

Neat little SBC I picked up recently on eBay. Was looking into the Raspberry Pi Zero W but ran across the Orange Pi Zero online while doing some research. It's almost twice the price, but your extra money goes a long way. A quad core 64 bit CPU, 8GB on-board EMMC, full size HDMI port, and several other features. You can see the specs here and comparing raspberries and oranges.

What really caught my eye was the mic input and audio output. I've been using home assistant on my pi 4 and was looking to offload the Almond open source AI virtual assistant along with Ada for voice control to another board to free up processing. What I like most about Almond is your info never leaves your network, unlike Google Assistant and Alexa, as it's built with privacy in mind.

So far all I've done is added a small spare heatsink to the CPU, installed Armbian from TF and moved the installation to the EMMC, and ran the sbc-bench benchmark test. See results below. More to come

========================================================================== 
== Memory bandwidth tests == == == == 
Note 1: 1MB = 1000000 bytes == == 
Note 2: Results for 'copy' tests show how many bytes can be == == 
copied per second (adding together read and writen == == 
bytes would have provided twice higher numbers) == == 
Note 3: 2-pass copy means that we are using a small temporary buffer == == 
to first fetch data into it, and only then write it to the == == 
destination (source -> L1 cache, L1 cache -> destination) == == 
Note 4: If sample standard deviation exceeds 0.1%, it is shown in == == 
brackets ==

========================================================================== 
== Memory latency test == == == == 
Average time is measured for random memory accesses in the buffers == == 
of different sizes. The larger is the buffer, the more significant == == 
are relative contributions of TLB, L1/L2 cache misses and SDRAM == == 
accesses. For extremely large buffer sizes we are expecting to see == == 
page table walk with several requests to SDRAM for almost every == == 
memory access (though 64MiB is not nearly large enough to experience == == 
this effect to its fullest). == == == == 
Note 1: All the numbers are representing extra time, which needs to == == 
be added to L1 cache latency. The cycle timings for L1 cache == == 
latency can be usually found in the processor documentation. == == 
Note 2: Dual random read means that we are simultaneously performing 
== == two independent memory accesses at a time. In the case if == == 
the memory subsystem can't handle multiple outstanding == == 
requests, dual random read has the same timings as two == == 
single reads performed one after another. ==
