[QUOTE=ButtsexV3;34251388]source?[/QUOTE] Don't want to look back into the past 20 pages, it has been mentioned plenty of times already.
[QUOTE=B!N4RY;34251474]Don't want to look back into the past 20 pages, it has been mentioned plenty of times already.[/QUOTE] it's been mentioned (and it it keeps getting less powerful) but it's never been cited.
This thing looks awesome, if this thing can run Diablo 2 then I am definitely getting it.
[QUOTE=Exuberance;34251610]This thing looks awesome, if this thing can run Diablo 2 then I am definitely getting it.[/QUOTE]hi there. READ THE FUCKING THREAD it doesn't support x86 architecture applications
[QUOTE=TehWhale;34251671]hi there. READ THE FUCKING THREAD it doesn't support x86 architecture applications[/QUOTE] hi there I assumed there was some sort of x86 emulator, also all I did was read the first 3 pages and ctrl f the rest with the term "diablo," I wasn't about to go through every page, no need to be an ass about it also nice 13000 posts, congratulations
[QUOTE=TehWhale;34251671]hi there. READ THE FUCKING THREAD it doesn't support x86 architecture applications[/QUOTE] This is why this thread belongs back in HW/SW section, and an OP that at least knows jackshit
[QUOTE=B!N4RY;34251770]This is why this thread belongs back in HW/SW section, and an OP that at least knows jackshit[/QUOTE]Yep. Would be nice.
-snip how the hell did I get in the wrong thread-

also I don't know about you guys but I'm gonna get a model A as well and see if I can't get RISC OS on there
[QUOTE=ButtsexV3;34251507]it's been mentioned (and it it keeps getting less powerful) but it's never been cited.[/QUOTE] The CPU in this thing is a ARM1176JZF-S running at 700Mhz, [url]http://www.shenit.com/blog/2010/10/22/comparison-of-chipset-of-android-tablet/[/url] references a SoC design using it as a core (Telechips TCC8902), it claims that when running at 720Mhz it gets around 3.5 MFLOPS on the Linpack test (More results for various phones here: [url]http://www.greenecomputing.com/apps/linpack/linpack-by-device/[/url]) This page ([url]http://www.spaennare.se/computer.html[/url]) shows a couple of different results for the 486 DX processor (running at 50Mhz and 100Mhz), showing that, while it's dependent on the compiler used, it still scores pretty well compared to the ARM chip used here. And for random bits of info, [url=http://www.xyster.net/blog/?p=40]the iPhone 4 is about as fast as a 166Mhz Pentium II[/url] Of course, all this varies based on manufacturing, architecture, workload, etc. Newer ARM designs are getting 10x the performance at a lower clockrate, etc. Part of the reason for the cheapness of the Raspberry PI is that the CPU used is older (It's also used in a bunch of Chinese tablets and cheap Android phones), it's not bad, it's just not designed to be a powerhouse (so no running Windows 8 on it, for multiple reasons) Edit: Comparing different architectures with different benchmarks is plainly wrong, but quite often people don't run the same benchmarks and versions across different CPUs. I've got an old 486 laptop here though, so I'll personally be benchmarking the difference when I get mine.
[QUOTE=ButtsexV3;34253555]also I don't know about you guys but I'm gonna get a model A as well and see if I can't get RISC OS on there[/QUOTE] Initially they're only fabricating the Model B, due to the high demand for that model among most hobby users. They'll start with the Model A when they're taken care of the worst of the Model B demand.

YES! Now i got a legit reason again to play with lego's again :dance:
I'd like to make a really neat small touchscreen-mediacenter for a car. Audio output goes to the AUX of the stereos and it uses its own media-player to play music from a usb-stick / harddrive or such. Only question is: is the cigarette-lighter-plug powerful enough to run it?

You guys think it could run DosBox at a reasonable framerate? Ok, the RISC OS Wiki says ARM has trouble emulating x86 quickly but what do you think?
No.
Has anyone made a Lego schematic based on the specs and measurements of the RPi yet?

[editline]17th January 2012[/editline] [QUOTE=Nikita;34250497]I'm thinking it can be used as a basis for some super-fancy 700 MHz lab equipment. Does anyone know, 700 MHz for ARM-6 is a rough equivalent of how many MHz for x86?[/QUOTE] No way to compare, both ARCHs have different performances under different conditions. (Task you're performing, optimization, etc.)
When I get home today I'm going to make a FAQ video because the repeating of questions is driving me insane.
Hey I just thought, since this thing obviously uses passive cooling, if any cooling at all, you could probably overclock the shit out of it if you threw it in mineral oil or used some effective active cooling. I dunno how possible that will be, who knows what kind of access the bios gives you on it, but if it is possible, keeping the temperature down shouldn't be difficult.

I dunno how possible that will be, who knows what kind of access the bios gives you on it, but if it is possible, keeping the temperature down shouldn't be difficult.[/QUOTE] From my experience with these boards, the system will just crash if you overclock something over the 'base clock', I might be wrong tho.
I've never researched overclocking ARM CPUs, so I've got no idea how one would go about it (You don't have the classical BIOS, hardware varies from board to board, etc.) Also, I wonder how much effort it's going to take to get other Linux distros on this thing, as the firmware/drivers for the GPU/DSP are closed source. They'd come with the system, but you'd either have to copy them off and adapt them to a new distro, or you might be able to just replace the distro that comes with it (It's apparently also the bootloader, so it's low level stuff)

About the DSP I'm not really sure.
What could I, as a not-extremely-techy person, do with this?
well, it would fit in a sandwich.
