Yes! I am waiting desperately for a Raspberry Pi with an updated CPU!

Try a Beaglebone Black. Or move up to something like a Boundary Devices unit (Quad-core A9 @ 1Ghz)
- Derbasti 13y ago
  Yes, I own a Beaglebone Black. But the operating system and the ecosystem surrounding it is oh so aweful compared to simply-Debian it-just-works Wheezy for the Raspberry Pi. That probably doesn't matter too much if you are building some embedded thing, but I am mostly using my Pi as a web server, and I like that is so easy to set up and configure.
  - joezydeco 13y ago
    Yeah, I agree, Angstrom is awful. I got Debian Wheezy booting off of the Black in under an hour or so. Sorry to hear you had difficulty getting it to work on yours.

    It's very easy to install ubuntu on a BBB. I have 13.04 and 13.10, both running from the eMMC and uSD cards. http://elinux.org/BeagleBoardUbuntu http://elinux.org/BeagleBoardUbuntu I own 1 rpi and 2 BBBs and all work just fine. I have the rpi 24/24h connected to a relay board and other things but tend to prefer the BBB due to the better CPU and easier to keep up to date with regular distros.

      OK, I'll try that.

    Arch linux "JustWorks(tm)" on BBB. Relatively easy to get a server going on it, and lxde running as a GUI isn't too shabby (noticeably better than a GUI on the PI). Only trouble with BBB is the lack of hardware accelerated graphics support (BBB has a graphics chip, but it's not working in any of the current kernels)

Check out the new and old cubieboard. Cheap, dual core, SATA.

  I have a Cubieboard, very happy with it. A new Cubieboard2 is on order. The 4 core A20 is pin for pin with the A10. Not to be off topic, I have three Pi-B's doing local file storage, media center and on a robot platform. The ecosystem around the Pi is one of the best. A quick search will find someone doing something like your idea.

    This thing will decode 4k video? http://www.romaco.ca/blog/2013/07/05/the-cubieboard2-the-most-under-hyped-credit-card-computer-you-should-definitely-buy/ http://www.romaco.ca/blog/2013/07/05/the-cubieboard2-the-mos...

What about the CPU are you waiting for? Higher performance? 64 bit vs 32 bit? And what is the application that is made possible by that you can't do now?
- Derbasti 13y ago
  More cores, mostly. I tried using the Raspberry Pi with server software such as Owncloud or calendarserver. It just barely works, but it is still very slow. Like, response times upwards of four seconds. Recent smartphone processors have since about doubled their clock speed and quadrupled the processor count. Even half that would bring response times below a second, which would be much appreciated.
  - justincormack 13y ago
    Its not really that slow; try different software. Low power means you need to be slightly efficient.

      Well, for today's software, it kind of is slow. Its IPC performance is about 1 DMIPS/Mhz vs ~3.5 for the latest high-end ARM chips, which also have 3x the clock speed of RPi, and come in quad-core variety. Do the math. That's a 10x-40x delta. Of course such a board wouldn't cost $30 anymore, but they could still improve performance by at least 3x with another low-end, but more modern, CPU, even as single core, but even more as dual-core or quad-core. Even a single core Cortex A7 at 1.2 Ghz would be about 3x faster than Raspberry Pi (90 percent faster IPC * 70 percent faster clock speed). Personally, I think they should wait until they can make a dual-core 1.5 Ghz Cortex A53 with 1 GB of RAM for $25, which may be possible by 2015, and maybe a quad-core 1.5 Ghz Cortex A53 one with 2 GB of RAM (and perhaps a few extra stuff), for under $50 (I would make it for $40-$45 so the total cost with shipping and whatnot still remains under $50 for most people, instead of going over that price point). A single core Cortex A53 at 1.5 Ghz (its stock clock speed) would be ~5x faster, and also 64-bit. By the way, Cortex A7 and Cortex A53 are both the true successors of the ARM11 CPU RPi is using, and they serve the same markets. The $25-$50 market, is still probably their best market, since a lot more companies compete at the $100-$200 level.

Me too, meanwhile I ordered a Beaglebone Black to test out, which has a bit better specs for heavy-CPU jobs. http://beagleboard.org/Products/BeagleBone http://beagleboard.org/Products/BeagleBone Black
