Raspberry Pi Foundation unveils new Pi that’s six times faster, will support Windows 10

Three years to the month after launch­ing the first Rasp­ber­ry Pi micro­com­put­er, the Rasp­ber­ry Pi Foun­da­tion has unveiled a new Pi that uses a more mod­ern proces­sor and has twice as much mem­o­ry onboard. The Rasp­ber­ry Pi 2, as it’s being called, will sell for $35, just like its pre­de­ces­sors (the first gen­er­a­tion Mod­el A and Mod­el B), but it is unques­tion­ably a bet­ter val­ue, due to its improved specs.

We at NPI were among those who bought a Rasp­ber­ry Pi when it first went on sale. Though the soft­ware has improved by leaps and bounds since the ear­ly days, we’ve always wished the hard­ware was bet­ter.

At last our wish has been ful­filled — and soon­er than we thought.

After boost­ing the mem­o­ry on the Mod­el B from 256 MB to 512 MB in mid-2012, the Foun­da­tion main­tained that no fur­ther upgrades to hard­ware were planned, at least not in the short term. From the Rasp­ber­ry Pi FAQ, cir­ca Decem­ber 2013:

When will the next model of the Raspberry Pi be released?

As of the end of 2013, there are no imme­di­ate plans for the next mod­el; pos­si­bly a new mod­el will be released in 2–3 years, but this is not a firm time frame. A new mod­el would inher­ent­ly undo much of the com­mu­ni­ty work that has been done to date on the Rasp­ber­ry Pi, which would be counter-pro­duc­tive to our edu­ca­tion­al aims. We con­cen­trate our engi­neer­ing effort on mak­ing the soft­ware that runs on the Rasp­ber­ry Pi faster and bet­ter all the time – which is why you should always be run­ning the most recent firmware. Minor hard­ware revi­sions, such as bring­ing out i2s on the Mod­el B rev. 2 board, will occur on an as need­ed basis and have no set time­frame or sched­ule.

Here we are just a year or so lat­er, and we’ve got the Mod­el 2. How did the Foun­da­tion man­age to pro­duce a new Pi while main­tain­ing the back­wards com­pat­i­bil­i­ty they’ve insist­ed was so impor­tant to them? Turns out Broad­com, the mak­ers of the sys­tem on a chip the Pi uses, were will­ing to lend a hand:

Nonethe­less, there comes a point when there’s no sub­sti­tute for more mem­o­ry and CPU per­for­mance. Our chal­lenge was to fig­ure out how to get this with­out throw­ing away our invest­ment in the plat­form or spoil­ing all those projects and tuto­ri­als which rely on the pre­cise details of the Rasp­ber­ry Pi hard­ware. For­tu­nate­ly for us, Broad­com were will­ing to step up with a new SoC, BCM2836. This retains all the fea­tures of BCM2835, but replaces the sin­gle 700MHz ARM11 with a 900MHz quad-core ARM Cor­tex-A7 com­plex: every­thing else remains the same, so there is no painful tran­si­tion or reduc­tion in sta­bil­i­ty.

Because the new Pi’s proces­sor has four cores that are each 200MHz faster than the orig­i­nal Pi’s proces­sor, the increase in speed is six­fold. There’s twice as much mem­o­ry too, as pre­vi­ous­ly men­tioned. The new P‑I unfor­tu­nate­ly does­n’t come with sup­port for USB 3.0/3.1 or giga­bit Eth­er­net, but a future Pi well might.

The new Pi will sup­port Ubun­tu as well as Microsoft­’s Win­dows 10 oper­at­ing sys­tem, which will delight any­one who has tried to get Win­dows to work on the Pi. The Foun­da­tion has always advised against this in the past. From the old FAQ:

Will it run WINE (or Win­dows, or oth­er x86 soft­ware)?

Wine Is Not an Emu­la­tor. Some peo­ple have put Win­dows 3.1 on the Rasp­ber­ry Pi inside an x86 CPU emu­la­tor in order to use spe­cif­ic appli­ca­tions, but try­ing to use a ver­sion of Win­dows even as recent as Win­dows 98 can take hours to boot into, and take sev­er­al more hours to update your cur­sor every time you try to move it. We don’t rec­om­mend it!

Will it run the Win­dows 8 ARM edi­tion?

No. Even if Microsoft decid­ed to devote all its resources to get­ting Win­dows 8 on the Pi it would not work. The Rasp­ber­ry Pi lacks the min­i­mum mem­o­ry and CPU require­ments, it runs on an ver­sion of the ARM proces­sor that is not sup­port­ed by Win­dows 8, it lacks the appro­pri­ate axis sen­sors… the list goes on and on. The Pi will not run Win­dows 8.

But the Pi 2 will be able to run Win­dows 10. From Microsoft:

We’re excit­ed to announce that we are expand­ing our Win­dows Devel­op­er Pro­gram for IoT by deliv­er­ing a ver­sion of Win­dows 10 that sup­ports Rasp­ber­ry Pi 2. This release of Win­dows 10 will be free for the Mak­er com­mu­ni­ty through the Win­dows Devel­op­er Pro­gram for IoT.

Win­dows 10 is the first step to an era of more per­son­al com­put­ing. This vision framed our work on Win­dows 10, where we are mov­ing Win­dows to a world that is more mobile, nat­ur­al and ground­ed in trust.

With the Win­dows for IoT devel­op­er pro­gram we’re bring­ing our lead­ing devel­op­ment tools, ser­vices and ecosys­tem to the Rasp­ber­ry Pi com­mu­ni­ty!

We see the Mak­er com­mu­ni­ty as an amaz­ing source of inno­va­tion for smart, con­nect­ed devices that rep­re­sent the very foun­da­tion for the next wave of com­put­ing, and we’re excit­ed to be a part of this com­mu­ni­ty.

We are excit­ed about our part­ner­ship with the Rasp­ber­ry Pi Foun­da­tion and deliv­er­ing a ver­sion of Win­dows 10 that sup­ports Rasp­ber­ry Pi 2, and we will be shar­ing more details about our Win­dows 10 plans for IoT in the com­ing months.

Win­dows 10 will also be a free upgrade, at least in the first year of avail­abil­i­ty, for peo­ple run­ning Win­dows 8 and 8.1 now. In mak­ing Win­dows 10 upgrades free (as in free beer), Microsoft is fol­low­ing in the foot­steps of Apple, which decid­ed to stop charg­ing for OS X upgrades in 2013 when it released Mav­er­icks.

Nei­ther OS X or Win­dows is free as in free speech, how­ev­er. Both oper­at­ing sys­tems con­sist of code that’s pro­pri­etary, or closed source. The var­i­ous oper­at­ing sys­tems that the Pi has run since its incep­tion (includ­ing Rasp­bian) are open source, mean­ing that any­one can see how they work and mod­i­fy them to their heart’s con­tent.

Owing to its nature, free soft­ware can­not be pirat­ed like Win­dows or OS X. Any­one who wants a copy of a libre OS like Ubun­tu or Debian can freely and quick­ly get one. Copy­ing free soft­ware is not only legal­ly allowed, it’s encour­aged.

Con­trary to what you might think, free soft­ware can actu­al­ly be sold (and some­times is), but its pur­chasers then have the option of redis­trib­ut­ing it gratis, if they wish. If they did­n’t have this free­dom, then the soft­ware would not real­ly be free.

We at NPI are firm philo­soph­i­cal believ­ers in free soft­ware, and we’re proud that our online pres­ence is pow­ered exclu­sive­ly by a free soft­ware stack. While it’s nice that Microsoft is sup­port­ing the Rasp­ber­ry Pi (just as it sup­ports Dru­pal and Word­Press), we’ll con­tin­ue to prin­ci­pal­ly pow­er our Pis with free soft­ware.

Con­grat­u­la­tions to the Foun­da­tion on the launch of the new mod­el. We’re anx­ious to put it to the test and see what it can do.
