Well that's embarrassing.
Why would a phone need a GPU comparable to that of a device that's supposed to work connected to a desktop monitor?

#12A sentence «and should double iPhone 4S performance across a range of content» is a really authoritative benchmark I suppose...

#13Wow, that makes this thing a lot more interesting to me, if true. So many designs these days pair monster CPUs with underpowered GPUs it's almost embarrassing (especially as Apple continues to show that powerful GPUs are important for a good user experience). The 256 MB of RAM will be very constraining for any app trying to use all that power, though.
Personally I think the fairly low amount of memory is good and works well with their motive - to promote computer science education. If it had more, you could easily chuck massive frameworks and whatnot at it, but as there's not as much RAM then hopefully people learning with it will have to work a little closer to the bare metal. I'm sure things to make Raspberry Pi work 'easier' will arrive - and that's not necessarily a bad thing - but at least they'll be more constrained.

Embarrassing? Remember that they're working without power constraints; it's a rather different problem.

My Archos 101 has 256MB RAM and runs Android suprisingly well. It only does 720p video playback though; full specs http://www.archos.com/products/ta/archos_101it/specs.html?co.... I'm not going to lie, it does tend to lag a bit; wonder how easy upgrading the RAM will be on the RPi.
Re: Raspberry Pi's GPU double the performance of iPhone 4S
#16Does the iPhone 4S actually use a Tegra 2? Everything I've read indicated it used a PowerVR GPU, just like every other iPhone, not a Tegra 2. The article seems fundamentally misguided and incorrect if this is the case.

#17shame the BCM2835 won't be open sourced anytime soon...
Looks like Mali will be the first ARM graphics core to get a free driver http://www.fosdem.org/2012/schedule/event/mali

I think the author is saying that the Broadcom GPU outperforms both the Tegra 2 (used in Android devices & netbooks) and the iPhone4S's GPU.

#19I don't care about the GPU, but I'm glad to see XBMC running on the thing.
Next up, I want to see some Ubuntu Pi edition, and perhaps even some ChromeOS fork.
My hope is to be able to attach that to the back of a monitor/TV and get a usable browsing and movie watching machine.

#20Little confused here. Has the Pi project changed from "low-cost education computer for the masses" into "iOS-killing mobile game platform"?
