As reported earlier, the Raspberry Pi is a small computer intended to run Linux and is made to be portable and able to be powered by USB. The small board is based on the Broadcom BCM2835 chipset, which includes an ARM 11 CPU and a dual core VideoCore IV graphics card co processor. The Raspberry Pi further includes connections for HDMI, component output, and USB ports. The higher tier $35 model will further feature an Ethernet jack and twice the RAM (512 MB).
The Raspberry Pi will soon be available for sale and if the company behind the device- The Raspberry Pi Foundation- is to be believed, the GPU in the little Linux computer will pack quite a punch for its size (and cost). In a recent Digital Foundry interview with Raspberry Pi Executive Director Eben Upton reported on by Eurogamer, Upton made several claims about the Raspberry Pi’s graphics capabilities. He explained that the Broadcom BCM2835’s VideoCore IV GPU is a tile mode architecture that has been configured with an emphasis on shader performance. Upton said “it does very well on compute-intensive benchmarks, and should double iPhone 4S performance across a range of content."
The comparison to the iPhone 4S relates to his further claims that the Raspberry Pi GPU is the best on the market and can best both the iPhone 4S’s PowerVR (Imagination Technologies) based graphics and even the mighty Tegra 2 in fill rate performance. Rather large claims for sure; however, we do have some independent indication that his claims may not be wholly inflated. The coders behind XBMC, open source media center software that allows users to play a variety of media formats, have demonstrated their XBMC software running on the Raspberry Pi. They showed the Raspberry Pi playing a 1080p blu ray movie at a smooth frame rate thanks to the Broadcom GPU being capable of 1080p 30 FPS H.264 hardware accelerated decoding. You can see the Raspberry Pi in action in the video below.
The little Raspberry Pi is starting to look quite promising for HTPC (and even light gaming) use, especially for the price! At $25 and $35 respectively, the Raspberry Pi should see quite the following in the modding, enthusiast, and education community.

The UK based charity behind the Raspberry Pi Linux computer, the Raspberry Pi Foundation, announced in a blog post that the two ARM 11 powered Linux computers have entered the manufacturing stage and are that much closer to going on sale. The two models, Raspberry Pi A and B, will be $35 and $25 respectively. The difference between the tow models is that the cheaper model A board has half the RAM at 128 MB and lacks an Ethernet port. Both models have an HDMI and analog RCA video output along with a USB port to attach a mouse and keyboard.
The charity elaborated that while they tried to find a manufacturing partner in the UK, they ran into cost and logistical issues. Specifically, tax and import laws in the UK requires any electronic components to be subject to import tax, making importing components into the UK and manufacturing it from within an expensive proposition. The Raspberry Pi Foundation was able to find a manufacturing plant that could produce computers for them at or above break even prices; however, they would not be able to produce enough units to meet demand- only a few hundred instead of the estimated 10,000 units the charity wanted. Further, because the manufacturing plants could only produce a few hundred units a month the release date would be months away instead of the 3 to 4 week turnaround offered by Chinese and Taiwanese manufacturing plants.
In the end, the charity chose to produce the Raspberry Pi computers outside of the UK in order to keep costs down and meet the release and quantity expectations. They will then use the savings to invest in further research and development and expanding the organization.
Are you guys going to purchase the Raspberry Pi computer when it comes out?

I must say, that unlike cake: pie is the foundation of everlasting relationships – like circumference and diameter! That, and cake always seems to end up in lies (yes, that horse is still twitchin’). While my personal favorite flavor is blueberry I might just become fond of Raspberry Pi in the near future. We originally reported on the organization dedicated to providing computing technology to the masses a few months ago when they showed off their prototype computer-in-a-usb-stick. More progress on the logistics as well as a firm specification on the PCB have occurred since then and it aligns nearly perfectly with original predictions.
That… doesn’t really look edible…

The original prediction was a $25 device 700 MHz device backed by 128MB of RAM and an OpenGL ES 2.0 1080p-capable GPU. While that is still true, a second model will be released for $35 with double the RAM and an extra USB port for peripheral connectivity due to the addition of the SMSC LAN9512 two-device USB hub. The alpha board is slightly larger than the final design due to the ports required for debugging purposes and contains an extra couple layers on the PCB that will not be present in the final version. It is still expected to ship within the next 9 months (12 from original post) with the target narrowed slightly to likely sometime in 2011.
