Raspberry Pi 3 Rolls Out With Faster CPU, On-Board Wi-Fi, and Bluetooth
An anonymous reader writes: The original Raspberry Pi went on sale four years ago, and more than 8,000,000 units have shipped since then. Raspberry Pi computers are used in schools and universities, in factories and other industrial applications, in home automation and hobby projects, and much more. Today the Raspberry Pi 3 was announced, featuring a 64-bit quad-core ARMv8 CPU clocked at 1.2GHz, making it roughly 10x the speed of the original Pi 1. Many people will be pleased to hear that the Raspberry Pi 3 also features on-board Wi-Fi and Bluetooth, greatly improving the device's connectivity. The new device goes on sale today at the usual price of US $35. (Here's the official announcement itself.)
But still the same ethernet that goes over the USB bus?
And? A 100Mbps ethernet interface is fine over the 480 Mbps USB2 bus. You're not going to be running an enterprise NAS on this thing now, are you?
The original USB ethernet had problems with the poly-fuses blowing out under load. That's not a problem now with later Pis.
BCM43438 wireless âoecomboâ chip.
Kill yourself. As a veteran Linux sysadmin seeing BCM in the lsmod or lspci for ANY machine is enough to make me dive out a window and head for the hills. Broadcom wireless --christ even broadcom wired -- is a whole other level of shit-tier performance in Linux. enjoy your frozen interfaces and unsupported modes.
To the Pi team: Why god why couldnt you have chosen something like an Intel or atheros?
Good people go to bed earlier.
Glad to hear that the RasPi Zero wasn't the only product on development from Rasp Foundation.
I had a lot of fun with tinkering with the Raspberry Pi 2 so far and that new Raspberry Pi 3 seem to be a step in the good direction.
More power and, finally, integrated Wifi and bluetooth. Something that seem more important and cheaper than many other hardware.
Still, there still a lot to be desired, both hardware and software. Analog IO, more power (USB 3.0?), better Python development tool and IDE (yeah, idle or idlex need a serious overhaul), and other stuff. Raspbian (or other Linux/ARM distribution) are a mess and I'm starting to put my hope on Win10 IoT.

These two sentences alone make me chose any of the innumerable competitor products, rather than R-Pi.
It's funny how people go on about "competitor products" but never bother naming them.
Probably because whenever they do, it turns out that they're either not comparable on price or on specs.
Actually there are many Chinese ARM-based development boards and "mini PCs" with much, much better specs. The problem is that they tend to use SoCs designed by some mainland Chinese semiconductor company which refuse, or at least ignore requests, to release even the GPL'ed kernel sources for the chip. Compared to these companies, Broadcom is almost saintly.
But still the same ethernet that goes over the USB bus?
You complain about this like it's a show stopping defect. For the few people who care about this, then there's alternatives to rasp PI. But for the vast majority of people, empirically, this is not a problem. Given the Raspi only has a gigbyte of memory or half that, where the heck are you going to put your data after 10 seconds at a gigabit?
Next you will complain your toaster having only 10Mb/set wifi is a major lifestyle issue.
Some drink at the fountain of knowledge. Others just gargle.
Why not run a NAS on it? The Pi3 is more than fast enough. Not sure why you'd bring Enterprise into it.
No excuse for it not to ship with USB3 at least.
Damn straight!
1. 100mbps is shite. It's an absolute pile of crap in 2016. Unless you live alone and think divx is kewl, 100mbps is pathetic for even the most basic of consumer expectations.
2. USB2 is shite, especially when its the primary bus for proper storage media.
As you say, there's no reason why the Pi3 cannot do NAS duties, but #1 and #2 render it bloody useless in today's minimum requirements.
The Linux based SoCs that cost < $5 (which you find in just about everything) already have 1gbps and USB3. There's no excuse for the new Pi to stick to last decade's tech when the cost is negligible. And to rub salt into the wounds, the drivers and code are proven and have been in the mainline kernel for ARM devices for fucking ages.
Bring the Pi into real world specs, and it'll take off. The board is barely used, it's a failure; and the singular reason is the same that all educational products fall into: it's fucking crippled!
If those that believe using a Pi for electronic needs is "da biz," then you're bloody crap at electronics. Learning FGPA tech is far more beneficial when it comes to education and real world usage. Turn the Pi into something usable, and it'll take off. Don't take my word for it, ask the man from Del Monte!
No, where did you read that the ESP8266 only has 1 GPIO? That's totally incorrect, it has 11 GPIO and you can have 2 more if you get one of the modules where two of the pins going to the flash - chip are cut or you cut them yourself for a total of 13 GPIO - pins. There is also one analog input pin. Also, you can run a web-interface on them, if you want to.
I have several ESP8266's myself and they are fabulous little devices and perfect for uses like this because they are so small, they use very little power and the built-in WiFi means you don't need any dongles or anything like that to make network-connected sensors and controllers. I have a small 2.8" colour LCD with touchscreen connected to an ESP with temperature/humidity - sensor, a PIR motion - sensor and a few more sensors in my use, and it works great.
rsync rather than scp to avoid CPU load due to compression/encryption
Unless you're using a customized ssh server and client with a "null" cipher, rsync will run over an encrypted ssh connection. If you want to see raw network throughput, you should use netcat:
