Orange Pi 4B Review: Raspberry Pi Competitor Has Built-in A.I.

There’s a lot of buzz around deep learning and machine intelligence these days, and almost every processor manufacturer claims it has the answer for accelerating the computationally-heavy workloads of building your own artificial intelligence. Intel is working on neuromorphic computing, inspired by the human brain, with its recently-scaled Loihi research processor; Nvidia, meanwhile, has products like the Jetson Nano which leverage its graphics processing technology as a general-purpose accelerator; Google has its in-house Tensor Processing Units (TPUs), launched for the enthusiast market in March last year and due a refresh early this year.

Debian 7 Through Debian Testing Benchmarks With/Without Mitigations

As part of our many Linux benchmarks in ending out the 2010s we ran tests looking at CentOS 6 through CentOS 8, seven years of Ubuntu Linux performance, and various other Linux distribution benchmarks and testing other important pieces of open-source software over time. One of the additional comparisons now wrapped up is looking at the performance of Debian GNU/Linux going back from the old 7 series through the current 10 stable series and also Debian Testing. Tests where relevant were done out-of-the-box with the default security mitigations and again with mitigations disabled.
