CherryPal: A 2-Watt Computer the Size of a Paperback

Cherry Pal: Green Computer
Many people only use their computers to check email, browse the web, do word processing, spreadsheets, etc. For them, many of today's PCs are overkill, but it's not clear what a good alternative would be, especially if they want low energy consumption. Enter stage left: The CherryPal, a tiny PC based on a Freescale CPU and the Linux (Debian) operating system. It's about the size of a paperback book and uses 80% fewer components than a regular PC. To make the trade-off acceptable, the CherryPal will use "cloud computing", meaning that many applications will run on an online server (same basic concept as web-based email). Read on for more technical specifications.
CherryPal Technical Specs
- Freescale's MPC5121e mobileGT processor, 800 MIPS (400 MHz) of processing power
- 256MB of DDR2 DRAM
- 4GB NAND Flash-based solid state drive
- WiFi 802.11b/g Wi-Fi
- Two USB 2.0 ports
- One 10/100 Ethernet with RJ-45 jack
- One VGA DB-15 display out jack
- Headphone level stereo audio out 3.5mm jack
- 9vDC 2.5mm 10 watt AC-DC adapter power supply
- 10.5 ounces
- 1.3" high, 5.8" x 4.2" wide
Don't let the relatively slow clockspeed of the CPU fool you. It has a different design from the current Intel and AMD processors so you can't compare it directly:
The MPC5121e processor is built around an efficient triple-core architecture consisting of a Power Architecture core, a 3-D-graphics processor core and a CD-quality audio processor core. The powerful 3D-graphics processor is engineered to provide a graphics pipeline capable of gaming-class 3-D rendering while keeping the DRAM bandwidth requirements to a bare minimum. The triple-core MPC5121e architecture is designed to allow the costly distributed DRAM memory systems within a PC to be merged into a single shared DRAM memory system.
They even claim it boots in 20 seconds.
The CherryPal is scheduled to come out on August 4th, 2008. No word on pricing yet except that the company says it will be "dramatically cheaper" than something like Asus' $400 EEE.

Might be perfect for my mother. Thanks !
Seems a good idea , a lot of people use the computer for basic needs- being in touch with each other , emailing and basic computing needs,this might turn out to be an ideal solution and of course a reasonably priced out .
2W? Wow. I'd buy it if I were looking for a new PC.
Don't let devices like this fool you. From the specs this thing can draw up to 10 watts once you add USB peripherals. Once you add a monitor, speakers, an internet router / cable modem and such you'll find yourself well over 100 watts. If you want to save power, and not have a severely gimped computer that requires an internet connection the EEPC or even a Dell laptop is a better choice. My 2 GHZ Dell laptop which contains everything I need to get more work done and more uses under 50 watts of power. It has the added bonus of letting me go outside with it too.
Perfect for so many people who aren't doing lots of video editing especially anyone who lives in those parts of the world with dry/dusty conditions that kill all pcs that have a fan fairly rapidly.
Ma, I've found you the perfect pc!
It's a pc not a PC. It doesn't have an Intel compatible CPU. It won't run any Microsoft software -- no Word, no Explorer no Excel, no PowerPoiint, probably not any Apple software either.
The UNIX guys have taken a couple of runs at this before with the Network Computer (Sun, Oracle, etc) and the SunRay. These were wonderful little machines but the lack of compatibility with the IBM (Microsoft/Intel) PC doomed them.
Maybe now with PDG (pretty darned good) desktop UNIX like Ubuntu, and RDG (really darned good) office productivity applications like OpenOffice not to mention EDG (exceptionally darned good) browsers like FireFox this new little beast has a chance.
Still. Don't rush out and get if for you mom unless you really know what you're doing.
I see a monitor port. I wonder if it will have an optional portable monitor for using it as a laptop...

The SunRay is still available from Sun. I had one on my desk. It was extremely cool not to mention cold (4 watts). It expects a server somewhere and a good connection.
google Sun SunRay or go here:

This is awesome. I've long thought small, less powerful computers would be great, but they just haven't been widespread. The Mac Mini was one example, but they're still pretty powerful and aren't necessarily cheap. I hope to see more of these on the market (but of course people could just stick with their old hardware, too).
Well, to respond on some of the power consumption things;
The MPC5121e CPU core is what takes up 2W. The chip is basically specified at a little under that, and has power management and with some clever software a drop down to just over 1W (turning off the display unit while the monitor is in standby etc.) should be possible.
USB devices cannot draw more than 500mA per port at 5V. A keyboard and mouse will rarely draw more than 50mA.
The RAM and NAND/NOR flash on the device will soak up a few more watts. Wireless and bluetooth is specified as power draws of similar to that you'd draw from USB - 500mA, at 3V or so.
And that's it. The system will probably still come in FAR below 10W (I'd estimate 5W for most people) with all it's units blazing at top speed and full performance, although most likely there is some tuning of the available software to make sure it does not get anywhere near that high. There is absolutely no way you can say that your Dell PC at 50W can "beat it". Adding a monitor doesn't make your point any more valid.
For clarity, just so you know, we design low-power boards like this at the company I work at. We have a very similar product which draws an average of 7W with an external graphics adapter (a Radeon), keyboard, mouse, USB flash drive inserted, as reported by my Kill-A-Watt, and plans for future products based around the same MPC5121e and MPC5123 processor lines.
You want a green pc, look no further then here, they are coming out with a green PC, if not the greenest PC in the world....besides the few watts the device takes, the rest runs off of solar power. Check it out here http://www.agreenpc.com
The device you use only sucks up about 5-6 watts of power, you should check it out.
Thank you for talking about the CherryPal C100. I am linking to this page from my blog, CherryPal for Everyone, at cherrypal dot blogspot dot com. I am excited about how the CherryPal can bridge barriers to people who have not had access to computers or the internet because of money, fear, education or other challenges. I will be commenting on my experience of using it on my blog as soon as I get my own CherryPal C100! You can use CODE CPP206 to get your own CherryPal for $10 less than purchase price when they are shipping (soon!) The best update I’ve gotten on availability is that the delay is due to a last minute decision to upgrade the solid state storage to a faster, higher quality version than planned. The hardware is working perfectly but the software requires some tweaks to fully optimize the OS to the new hardware. I think its worth the wait as there is nothing else available at the price point of $239 (using code CPP206). Come visit http://cherrypal.blogspot.com for updates. I am an anticipated fan with interests in cloud computing, green washing, sustainability and cheap, reliable connectivity.
