When you've enabled the internal WiFi -one of the boards USPs- it definitely needs 2.5A, preferably 3A (A as in Ampere). Over all it seems to have less variance in processing times than the Pi B+ or the Pi 2, where processing varies wildly between 6 and 12 hours.Įdit: It seems that the Pi3 is somewhat more power-hungry than its older brothers. Since the Pi 3 has managed a 5.33 and two others very close to that. The sole Enigma WU that managed to slip through was finished in a little over 9 hours, comparable to my augmented Pi 2, the one with the extra Hardware Floating Point and Integer libraries.Ģnd Enigma Wu went in 5.36 hours, a Raspberry record with me (previously stood at 6 hours). I've set Asteroids to 'No New Tasks', so in a day or three I can compare the Enigma scores as compared to my Pi 2s. As the Pi 3 downloaded four Asteroids WUs, taking 85+ hours (!) each, I can't go into further detail yet. Basically you have a 64-bit CPU on a 32-bit system with 1GB RAM, like in the olden Athlon64 days (even with comparable MHz.)īOINC-wise the Whetstone and Dhrystone MIPS are roughly the same as with the Pi 2, just slightly higher because of the 1200 MHz of the Pi 3 vs 900 MHz of the Pi 2 (1000 MHz when OC-ed). The lesser advantages are the 64-bit ARMv8 architecture and instruction set, that unfortunately aren't being used in the present Raspbian builds, partly because the Pi 3 is presently limited to 1GB of RAM because of the used Video Core IV GPU (why don't they give each CPU core its own GPU?). The main advantages of the Pi 3 are the build-in WiFi and Bluetooth and the higher Clock- and RAM speed. Through Synaptic I installed some extra 'integer' related files and behold:Ĥ89 floating point MIPS (Whetstone) per CPUġ944 integer MIPS (Dhrystone) per CPU a nous les petites françaises!. Now to unlock the secrets of integer performance Still not quite the values of our amphibious friends yet, but quite an improvement. Through Synaptic I installed some extra armhf related files and see:Ĥ89 floating point MIPS (Whetstone) per CPU and As my work as DHL courier took a forever greater part of my working days, I was unable to change this until one free evening. It seemed that those froggies must have had installed Debian Jessie -but in 2013?- in order to get the NEON capabilities of the RasPi2.but installing Jessie got me no further than 293 MIPS floating point MIPS (Whetstone) per CPU and 1163 integer MIPS (Dhrystone) per CPU -and a more up-to-date BOINC client (7.4.23).Īfter a while my Raspi2 hickupped and refused to work. Even when OC-ing to 1000 MHz I got stuck at 292 MIPS floating point MIPS (Whetstone) per CPU and 1143 integer MIPS (Dhrystone) per CPU: worse than the RasPi 1 at that speed! So I searched for an answer. Much to my chagrin I could not obtain these values myself. Quite suspicious: the posting dates from July 2013, long before the RasPi 2 hit the market. These MIPS values I had taken from a L'Alliance Francophone forum.
