Raspberry Pi 1 Model B

The Raspberry Pi is a credit card-sized computer with an ARM processor that can run Linux. This item is the Raspberry Pi Model B, revision 2.0, which has 512 MB of RAM, an Ethernet port, HDMI output, RCA composite video output, audio output, two USB ports, and 0.1?-spaced pins that provide access to general purpose inputs and outputs (GPIO). The Raspberry Pi requires an SD card with an operating system on it (not included). The Raspberry Pi is very popular, with lots of example projects and information available online.

Memory:
512MB RAM

Connections:
2 USB ports
Ethernet port
3.5mm jack for audio out
HDMI
Composite Video

Processor:
SoC is a Broadcom BCM2835
This contains an ARM1176JZFS (ARM11 using an ARMv6-architecture core) with floating point, running at 700Mhz, and a Videocore 4 GPU.

GPU:
The first version of the GPU used came out in 2009.
Capable of BluRay quality playback, using H.264 at 40MBits/s.
Has a fast 3D core accessed using the supplied OpenGL ES2.0 and OpenVG libraries.
Provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode.
Capable of 1Gpixel/s, 1.5Gtexel/s or 24 GFLOPs of general purpose compute and features a bunch of texture filtering and DMA infrastructure.
That is, graphics capabilities are roughly equivalent to Xbox 1 level of performance.
Overall real world performance is something like a 300MHz Pentium 2, only with much, much swankier graphics.
