Made a little video with a speed comparison between the (old) #DM42 running the #C47 firmware and the new #R47 hardware #calculator from #SwissMicros. 👉 https://youtu.be/BZqVe10dhRc?si=PJIPC-fijwFeF_UL – The R47 (which is, in fact, a DM42n hardware under the hood) is pretty much exactly three times faster – at least in this little, single use case of #primefactorization. #math
