What's the same: - Same form factor as the model B+ (your enclosures and daughter boards should still fit). - Same full size HDMI port - Same 10/100 Ethernet port - Same CSI camera port and DSI display ports - Same micro USB power supply connection What has changed: - A new turbocharged Broadcom BCM2836 900MHz quad-core system-on-chip with performance at least 6x that of the B+. - 1GB of RAM Source: http://raspberry.piaustralia.com.au/products/raspberry-pi-2-model-b http://raspberry.piaustralia.com.au/products/raspberry-pi-2-...

Under the "Same" column, it looks like you need to add "Same price - $35". I stocked up on B+s over Christmas - oh well... The "at least 6x" performance claim should be "at least 3x" by the way, and even that is an estimate, not a guarantee. The 3x is on a single thread comparison, the 6x is on a somewhat synthetic multicore benchmark test.

  Can you return them? If its less than 30 day...?

    In the EU, the consumer rights directive allows you to return most goods bought online up to 14 days after delivery.

  The Cortex-A7 is also faster per-core, per-clock than the old ARM11 processor, and the clock is higher. So with 4x the amount of cores, some multiplier for the per-core, per-clock stats, and 1.28x the clock, 6x makes some (marketing) sense.
  - arbuge 12y ago
    You might get 6x on some multicore benchmarks but for most applications in real life it's safe to say you're unlikely to see that.

    I bought on on Dec-31. Three weeks later, the bundle that I bought dropped in price. Amazon price-matched it and then less than two weeks later...

What's the same: Broadcom is still the non-datasheet-releasing, our-chips-implementing-standard-phy-spec functionality are subject to manhattan-project secrecy, assholes.
- jacquesm 12y ago
  Why are they required to release those datasheets?
  - seba_dos1 12y ago
    They're not required, but (thankfully) we're not required to use hardware from vendors that don't do that.
    - crdoconnor 12y ago
      There might come a point where essentially nothing on the market is open anyway, however. Meaning we are required.
  - greyfade 12y ago
    They're not, but it's been common practice in their industry for decades, and it's generally seen as beneficial to OEMs and users to have access to datasheets before purchase. This is why it's also commonplace for most chip manufacturers to offer free samples, even of chips upwards of $20 list price. Most of them even publish enough information to develop hardware and software to interact with these chips even without one on hand. That Broadcom doesn't do this is very atypical.
    - jacquesm 12y ago
      Ok. I find it rather rude to call a company 'assholes' for doing something that is 100% within their rights. They're releasing a chip that powers a relatively cheap fairly powerful computer, have supported the effort in as many ways as they could without giving up their competitive edge (when you're in a leadship position it is sometimes quite risky to open up too far), nobody forces anybody to buy the product and lastly you can of course always fire up the disassembler and do it the hard way.

What about power consumption? I know it is the same power supply (5V, 1A), but this doesn't mean it uses the same amount of power...
- Tepix 12y ago
  The official power supply has 2A.

Will Mathematica still ship with it and will the 6x performance increase make it be actually usable? What's the per-core increase?
- fulafel 12y ago
  Real-world max for single-thread speedup is probably the 3x quoted for the cache-busting SunSpider benchmark, with around 1.5x being more common. In terms of issue width, the new core is only a modest improvement as the Cortex-A7 is largely single-issue.
- benn_88 12y ago
  It will continue to be available, but I'm not sure what the performance increase is. There'll be a blog post on walkingrandomly.com coming in a few days - a guy who benchmarked it when it first came out. See http://www.walkingrandomly.com/?p=5220 http://www.walkingrandomly.com/?p=5220

  "... Best of all, the Pi 2 keeps the same shape, connectors and mounting holes as the Raspberry Pi B+ ..." Phil, does this means the case (model A+) used in the 'Touch Pi' will be modified to fit the Pi2 at some stage? cf: https://learn.adafruit.com/touch-pi-portable-raspberry-pi https://learn.adafruit.com/touch-pi-portable-raspberry-pi & https://learn.adafruit.com/3d-printed-raspberry-pi-b-plus-enclosure https://learn.adafruit.com/3d-printed-raspberry-pi-b-plus-en...
