Raspberry Pi 3 already!

and just two months after I bought a Pi 2 from Microsoft Store. Here are some highlights, possibly inaccurately remembered. Better - Arm A53: significantly faster than the A7(?) in the Pi 2. 64-bit - built in bluetooth and WiFi. These apparently go through SDIO, bypassing the USB bottleneck. - faster clocking for the GPU (I think) Worse: - takes more power to run. You might need a new power supply Same: - no price increase! - same case and peripherals as Pi 2 (but LEDs move) - all USB is 2.0 (no USB 3.x) - too much goes through a single internal USB 2.0 bus (ethernet, 4 usb ports) - although the processor is 64-bit, the software is still 32-bit. I hope that this will change. - 1G of RAM

I have seen a FLIR image that suggests that these are going to run a lot hotter than the Pi2. I am definitely interested, but I'd like to see something definitive about heat, power and performance testing before leaping into the fray. I am less worried about the 32-bit software, because I am not likely to run Raspian on one - I usually end up with a Debian, except for my media player, which is running XMBC. sincerely, William Witteman ww@witteman.ca 418-571-2432 william.witteman.ca On 2 March 2016 at 16:13, D.

What about the GPU? Is it supporting OpenGL? On 16-03-02 04:13 PM, D. Hugh Redelmeier wrote:

It already is. RPF release beta drivers last month with big "this is unstable" warnings. I've been running them for a while, and haven't noticed anything amiss. Now, I haven't been exactly torture-testing it, but the speedup is useful. I do like the idea of BLE on board. Handy. cheers, Stewart

A friend of mine in .nl says he got physical delivery of an RPi3 already earlier today. Not just hype it seems; too many product announcements have no apparent link to present-day reality.

And in a lot of applications built-in wifi will cover your networking needs, freeing up USB bandwidth entirely for other uses and saving a cable's worth of clutter. (And when each cable is another chance to haul the poor wee computer straight off your desk that has to count for something!)

As long as it's still happy running fanless I'm happy too.

It's early in the day everywhere for 64-bit ARM. It's a release architecture in Debian Jessie, though, so the software exists. Although the original Raspberry Pi had a bit of a weak processor and required a custom respin for that chip (Seneca at York's Fedora, or Raspbian) RPi2 supports real armhf[0] and one expects similar work will see 64-bit Jessie running on the RPi3. And with any luck all this will be integrated into the vanilla distro for the next release. [0] https://www.collabora.com/about-us/blog/2015/02/03/debian-jessie-on-raspberr...

I haven't had my Pi 2B or Pi Zero for that long and I found out about the 3B that came out on the 29th. Its tempting to get one but I already have three flavours of Pi. I don't really need a fourth. -- Cheers!

I meant to add that the suggestion is a 2.5A supply instead of a 2A one that was suggested for the 2B. -- Cheers!

Though if you actually want one, you have to pay the Newark tax. Seeing as canadarobotix.com hasn't crashed yet*, they don't have any in stock. cheers, Stewart *: it did the day the Raspberry Pi 2 became available, and as they run their POS terminal from the website, it was a fraught afternoon in the store. Us nerds don't do anxiety well.

Friend placed a order for himself and me directly from the UK. Works out to about $66CDN shipped. On Thu, Mar 3, 2016 at 9:11 AM, Stewart C. Russell <scruss@gmail.com> wrote:

About 50% faster as far as I can tell.

Or at least use a different bottleneck and won't get the the way of USB.
- faster clocking for the GPU (I think)
Yes 400MHz rather than 250MHz. Hence it can now do 1080p60 rather than 1080p30. I think they said 3D performance is up about 20%, while video decoding is up by 40% or so.
Worse:
- takes more power to run. You might need a new power supply
It does use a bit more, just like the Pi2 used a bit more than the Pi. The Pi 3 apparently needs 2.5A 5V supply.
Same:
- no price increase!

Well nothing prevents you from building and installing 64bit software. Of course with only 1GB ram still, there might not be any point, although using the 64bit isntruction set in 32bit mode would gain some nice new features (which is what the Cortex-A32 is made for, which is an A35 with the 64bit support removed, saving 10% power)

They did change it from 450 to 900MHz ram though. -- Len ~orensen

The 3 is about 50% faster than the 2B which makes it about 10 times faster than a 1B. -- Cheers!
