Raspberry Pi Upgrades Compute Module With 10 Times the CPU Performance (arstechnica.com)
An anonymous reader quotes a report from Ars Technica: The Raspberry Pi Compute Module is getting a big upgrade, with the same processor used in the recently released Raspberry Pi 3. The Compute Module, which is intended for industrial applications, was first released in April 2014 with the same CPU as the first-generation Raspberry Pi. The upgrade announced today has 1GB of RAM and a Broadcom BCM2837 processor that can run at up to 1.2GHz. "This means it provides twice the RAM and roughly ten times the CPU performance of the original Compute Module," the Raspberry Pi Foundation announcement said. This is the second major version of the Compute Module, but it's being called the "Compute Module 3" to match the last flagship Pi's version number. The new Compute Module has more flexible storage options than the original. "One issue with the [Compute Module 1] was the fixed 4GB of eMMC flash storage," the announcement said. But some users wanted to add their own flash storage. "To solve this, two versions of the [Compute Module 3] are being released: one with 4GB eMMC on-board and a 'Lite' model which requires the user to add their own SD card socket or eMMC flash." The core module is tiny so that it can fit into other hardware, but for development purposes there is a separate I/O board with GPIO, USB and MicroUSB, CSI and DSI ports for camera and display boards, HDMI, and MicroSD. The Compute Module 3 and the lite version cost $30 and $25, respectively.
I don't understand the rational behind a 4GB flash card? My rpi has a 64GB USB drive. Maybe speed perhaps (?), but even with going through USB it has enough throughout for almost any application in its class.
Sill only usb bus for storage, networking, etc?
Raspberry Pi one can easily emulate Nintendo. I have Emulation Station/RetroPie running on a Raspberry Pi 3 and it runs NES, SNES, SEGA all fine. Even works for some N64 games pretty well.
The article shows a picture of it being used in the back of an NEC monitor.
Are there any other examples of industrial controls or places that these live?
The pie 3b about an hour and a half or 15 minutes the second time to stick the pie in a case w/heatsink plug into hdmi and peripherals write the retropie image to an sd card boot the thing up and configure it.... (it's mostly configured just out of the package not including getting roms copied to it) it does all of the nintendos up to n64 very well along with the older stuff atari, mame, celecovision, etc... (if you have a lot of roms you may also want to look into sselp/scraper on git hub)
if you have trouble with sound from the hdmi... https://www.raspberrypi.org/do...
It also runs good with raspbian, it would easily make a good little general purpose computer for checking email, facebook, streaming video or music. OSMC works good on the pie 3b and is a snap to configure also.
I can't wait for the next version.... I hope it has more ram.
But can you run a Beowulf cluster on it?

Red Hat Linux and CentOS require at least 200MB of disk space. The smaller Pi option has 20 times that. It can hold 20 separate installations of Linux. Often, that's enough. When it's not, use an SD card.
Looking at it another way, for some projects I choose between an Arduino and a Pi. If it's too big for the Arduino, I use a Pi. Some projects are borderline, things that *could* be done with an Arduino, but it would be a stretch. The Arduino 32K-256K of storage. So the Pi has several thousand times as much.
Depends on how accurate you want it to be. If it's very close to accurate, it'll take several more generations.

These are still better specs than your average, slow as molasses cable box.
ARM was British, now Japanese.
Any other SoC provider is free to offer a comparable cheap option. Let me know when that happens, OK?

I'm waiting for the "soldering gurus" who were screaming why the original RPi was not sold cheaper in component kit form to get the Lite model and solder their eMMCs on those empry BGA pads.
I remember all the boasting about them reflowing huge multilayer PCBs in their kitchen oven.

So how long does it really take to get a raspberry PI up to emulating a nintendo and is it as nice to work with?
It took me about 6 hours.
That was:
- about 5 minutes to download retropie
- about 2 minutes to write the image to an SD card
- about 5 minutes to do first boot and get the pi on my wifi
- about 1 hour to download the full tosec ROM packs for NES, snes, sms, gbc, gba, atari (2600+7800), and tg16
- about 4 hours to convince Windows to ungzip the individually gzip'ed ROM files using 7zip on the command line and delete the archives, while sorting out only ROMs with a "[!]" marker in the file name (aka "known good and latest version") and deleting the rest
- about 30 minutes to copy the ROMs over wifi to the retropie system in their respective emulator ROM dirs
If you already have your ROMs stored locally in uncompressed format, that should cut the entire process down to under an hour.
Of course officially you should only be downloading ROMs of games you already own on cartridge if you want the whole thing to be legal. But I'm not your mom :P

Hell, I've had a Raspberry Pi one emulate a frickin' IBM System/370 mainframe.
And it probably runs faster than the original did!

TI does
Samsung does
There are a Whole slew of them

The chips the Broadcom originally based the RaspberryPi from were designed in Cambridge, England.
There's a torrent for a 128GB sd image that has damn near every game ever made for NES, SNES and a bunch of other old consoles on it. I downloaded it and after writing it to a card I booted and was playing games a few minutes later. It's so easy it's almost stupid. Rpi3 is great until you get to N64 and dreamcast stuff. That's asking a little too much although some of the N64 games seem playable. Earlier than N64 and it's no problem at all. Haven't tried overclocking it yet.
perhaps you are confusing one of the more modern variants with the 370. the 370 backplane could not come close to even to the I/O throughput of a Pi. but that is hardly surprising given it is over 40 years old.
They can be overclocked. The Raspberry Pi 3 has a newer ARMv8 SoC which runs a bit hotter than the previous SoCs they have used.
I'm going through this process at the moment; I have a Pi3 in the official Pi case running Lakka (an OpenELEC distro with RetroArch on top of it, designed exclusively for emulating a fair number of classic systems).
Like other people, I've found the Pi3 is perfect for emulating 8-bit, 16-bit, and some 32-bit consoles, but struggles a bit with some - Atari Jaguar and Sega Saturn seem to be way too slow to use, while N64 is just a bit too slow. PS1 emulation works pretty well, but gets choppy in some places.
I want to overclock my Pi3, so I have bought and fitted some heatsinks (one to the SoC and one to the USB hub/Ethernet controller chip). I have drilled ventilation holes in the underside of the case to allow cool air to get in to the RAM chip, which sits on the underside of the board. I have drilled ventilation holes in the lid of the case, along with holes to allow me to fit a 30mm 5v cooling fan. Then I fitted such a fan, and found it to be the loudest, whiniest, most irritating sound in the world. So I threw it away and have ordered a 40mm 5v fan from a company who specialize in making silent PCs instead.
He's Jesus, for Christ's sake.
Oh, forgot to mention - Lakka includes plug-and-play drivers for various game console controllers. I use my PlayStation 3 DualShock controller with it; absolutely zero setup required. You need to connect it up wired at least once, but then you can configure it to use the controller wirelessly (Pi3 has built in WiFi and Bluetooth, but older Pi units would need to have USB dongles to replicate the same functionality).
Lakka can also use ROMs and BIN/CUE files that have been shared from a NAS, but it does require a teeny little bit of command line usage to do.

Sort of comparable. Single-core Cortex-A8 is roughly what you had with the original RPi. Quad core Cortex-A9 is nicer but I bet you still get shitty firmware for it - that seems to be not just the norm but rather the ubiquitous default. When I said "SoC providers are free to offer a comparable cheap option", I also meant opening the software so that it could be used for something else than running Android. RPi people have so far been pressing hard for the graphics to work in things that aren't Android, for example.

I'm up to a 1.5 ratio on it now. Not going much past 2 to 1 so you better get after it.
And Retropie still doesn't use higan - mostly forks of Snes9x, which is not accurate at all.
The future is now if you're buying a commodity PC, not a low-powered ARM CPU.
I would suggest reconsidering the BeagleBone. Although not well advertised, it also contains two dedicated 200MHz cores that have full access to the main memory, and IO space as well as having their own cache. Unless you absolutely need 4 full cores of a Pi2/Pi3, I think you will find the BBB to be an excellent choice. It is also 100% open. I have a copy of the PCB designs tucked away and if it ever becomes necessary, I can have justa bout any PCB shop make them for me.
Also get a look at that last list, there are a bunch of options all over the spectrum of price, CPU performance and IO options, so there is likely to be something for everyone.
I would also like to note that the RPi foundation has caused me personal grief once already by EOLing the original Pi B and B+. We used to use hundreds of those things, but when they stopped making them, we had to switch to the Pi2 / Pi3. For most things that isn't a big deal, but these were part of a CE compliant device, and when we switched to the Pi3 we had to redo the compliance which cost $220K. We use about 5,000 per year, so it effectively added $40 to every unit we sell if we amortize it over a single year. Pretty shitty deal. All of our new designs are dual use, so we can continue using the Pi3s, but when they get EOLed, we are going BBB, or whatever they come out with for the next rev. In short, the RPi is a neat toy, but that is all it will ever be. There are plenty of other options that are in it for the long haul.

I haven't tried Retropie, I use Lakka (which runs on OpenELEC and runs Retroarch as the UI) and the Pi3 boots to UI in under 10 seconds from cold.
