The Graviton 4 is now in general release. While waiting for funding and approval to spin up a 4-core virtual machine, I thought I'd test the Pentium J5040 in the soft router that Fido just installed for the dog house.
I suggested an N100, but since there was 8GB of DDR4 left over from a laptop upgrade the older unit was procured. The dog developer has been acting uncharacteristically frugal due to the current world economy,
The results wereas well asThe Fourier Transform seems a bit slow--possibly due to the 2400 MT/s RAM repurposed from the laptop. On the other hand the balance between the four efficiency cores was pretty even. After running the Pi Race 7 times, each of the animals had won at least once.
