Nice update, and still at the $35 price point. Too bad it's still ARMv6. It would be nice to have ARMv7 which is where all of the high performance stuff is.

Edit. I take that back, it will be ARMv7 arch. Other articles state that the new Broadcom SOC will be using A7s. That makes it huge for this price point.

Earlier quoted context omitted.

It doesn't look like BCM is intending to release any more datasheets/programming information either, which is not surprising. There will probably never be any detailed information released, officially or otherwise, on any BCM SoCs, even after they're long EOL'd. As far as openness is concerned the RPi is basically a smartphone/tablet SoC devboard, with most of the hardware proprietary - while its Chinese competitors…

Or this: http://www.hardkernel.com/main/products/prdt_info.php?g_code... Quad core, 1 GB. Released just 2 months ago. Same price as the Pi.

It's not just the hardware peripherals, tutorials, books and community count for a lot also.

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.…

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.

Except that Broadcom released "full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack under a 3-clause BSD license" [1], enough to enable a blob-free graphics driver. Code has already been committed to Mesa [2].

That is a lot more than you can say about the PowerVR core in the Beaglebone advocated by another response to this post.

If only uploading the proprietary GPU firmware wasn't necessary to just launch the CPU, even at the cost of 3D acceleration and stuff like that, I'd be happy with it. It may even have reflashable closed blob inside - I know RMS wouldn't be happy with that, but I would. RasPi 1, however, required the user to provide a non-free blob on SD card, which is what I'm extremely unhappy with.

What does this really matter? A closed blob is a closed blob, it's not like the cpu itself isn't a closed blob. Now on the other hand, if the closed blob entails that functionality you expected can be taken away from you without your control, that's a different matter. Sure, I don't put it far beyond Broadcom, but that's a different matter.

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...?

Agreed. Among all the SBC forums, the Pi's is the friendliest community I've come across. You're almost guaranteed to get a reply and it's usually a useful one.

Anyone know where this can be purchased now?

Could not find it at the standard resellers yet… maybe on Monday (Feb 2) morning?

Will Mathematica still ship with it and will the 6x performance increase make it be actually usable? What's the per-core increase?
