Raspberry Pi 3 Model B+ Benchmarks Show Significantly Improved Performance (phoronix.com)

Posted by BeauHD on from the new-and-improved dept.

fstack writes: Pi Day was marked this year by the launch of the Raspberry Pi 3 Model B+ as the next evolution to this $35 ARM single-board computer. Phoronix has now put out Raspberry Pi 3 B+ benchmarks showing that the Ethernet performance is indeed much faster now but still doesn't stack up to other high performance boards, the SoC temperature is noticeably lower than the very warm Raspberry Pi 3, and the overall performance is a nice upgrade while retaining the same price point as its predecessors. Follow up tests looking at the Wi-Fi performance also show the new 802.11ac dual-band wireless to be much faster as well.

      One of the advantages of the Pi is that you have a HUGE ecosystem around it. If you have a question, the odds are that somebody else has had the same one. The distros are updated fairly often, and you can get custom distros to do one specific thing (like retro emulation or media center, for example).

      The problem with any non-Pi single-board computer is the lack of support.

      The C-2 looks cool, but Ubuntu 16.04 (almost two years old) is the latest Linux supported. Want android? Android 5.1 (over three years old). The Ubuntu is one of the LTS versions, but we are due for a new LTS next month. Will that be ported? Who knows?

      The two other Odroid boards (XU4, more powerful, C1+, less powerful) look even worse! Ubuntu 15.04 (almost three years old, and NOT an LTS version). Android 4.4 (over four years old).

I'm hoping that the new version will have enough resources to run OnShape.

The cool thing is that the current version of the Pi-3 is powerful enough to run TensorFlow, so our robots (which use Pi-3's) can actually do camera based machine learning (we do the training on regular PC's, though it can be done rather slowly on the Pi-3).

      I don't think you understand what OnShape is. It is web based CAD created by some of the original developers of SolidWorks. It runs almost entirely in the cloud. It can be run on phones, iPad's or old crappy computers. And it is arguably better than SolidWorks. Some universities are literally considering dropping SolidWorks for OnShape because it is so easy to support. All it needs is a browser that can run WebGL. I've been running it with old Core 2 Duo's with crap low end video cards, and it runs perfectly well. There are no typical CAD workstation requirements because most of the computation is being done off site. So, if the new raspberry Pi 3b+ is capable of running WebGL, then then it most definitely COULD be a CAD workstation.

      OnShape as well as many other Web-based CADs (did you try the TinkerCad?) use client-side rendering (projecting a 3D object into 2D screen surface). That is, the client's (here the PI or whatever your students are using locally) CPU/GPU is processing a 3D instructions of WebGl and plotting it to the 2D screen - a lot of floating point math involved.

      WebGl (see: https://en.wikipedia.org/wiki/...) is client-side rendering functionality.

      RPi has a 'decent' GPU (measured by cost and power) but it is limited, esp with respect to the memory size and number of FLOPs and likely memory bandwidth. Usually, CAD models are complicated enough to demand more resources. All in all you are going to make the students suffer through a sluggish process.

      >> It runs almost entirely in the cloud.

      If it did it would not need WebGl. The cloud would render the 3D into a 'picture' surface and serve it back to client. I do not think this is how it works. All in all it would make the UI rather sluggish as the round-trip latency would be remarkable.
