After studying the output of the Ryzen 5800X3D Fido's tail stopped wagging and the dog developer admitted there was a downward trend over the entire runtime. As an alternative to shoddily constructed on-premise computing resources, I decided to run the same tests on the free 4 core ARM instance in the Oracle cloud.The greatest average Flops rate for the Ryzen 5800X3D occurred with an array size of 767. As averages can be deceiving, I decided to plot the time evolution of Flops over the first 100 seconds of execution to see how the two runs compare.It looks pretty close, but not quite as consistent as the Pi 4B, Celeron or Phenom graphs. I think additional tests need to be made once Summer arrives. I wonder how consistent a laptop would look.
After determining things run fast for an array size of 2048 I obtained
The graph looks much different than the Ryzen 5800X3D. Rather than a boost which fades over time, the sustained Mflops for the Altra are steady at around 8930 Mflops but with random drops in performance about every thirty seconds.
I wonder whether those drops are related to services within the virtual machine that run every thirty seconds or whether some housekeeping functions periodically run outside the virtual machine.
