I wish they would release one with DMA based gigabit Ethernet. That always seems to be the bottleneck for me.

It would have been much sense with the newer CPU. My old Pi hiccups at very high IO over ethernet, specially when I am processing the incoming streams.

Same here; I've found the CPU to generally be the limiting factor, with IO (network or disk) only sometimes coming into play. The somewhat faster CPU could definitely help in this regard, but doesn't the network jack go through a USB 2.0 bus? If that's the case, that's probably the limiting factor.

Earlier quoted context omitted.

Broadcom is still Broadcom.

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…

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.

Awesome!! I just wish they would release one with onboard Wifi instead of ethernet. I have no statistics to back this up, but I'm pretty sure that USB Wifi adapters would be the most common accessory.

I use the onboard ethernet pretty constantly, mainly because I find the wireless to be finicky and hard to troubleshoot when you're running a headless setup. I can always plug in an ethernet cable, though...

ARMv6 still? I don't see how that's necessary to save on the BOM. I hope legacy code was not the deciding factor here.

That was pretty much my feel as well. So much for "now the CPU's fast"... yeah nope.

I thought the issue was mostly about lack of support?

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.

While a bit more expensive, I purchased a Hummingboard [1] instead of a Pi, and the performance was great! I had a NodeJS/Postgresql app running on it for kicks. I was surprised at how quick it was. [1] http://www.solid-run.com/products/hummingboard/linux-sbc-spe...

the entry level model is 70 bucks. Its a bit more than a bit more expensive.

Why are they required to release those datasheets?
